技术领域Technical field

本发明涉及轨道车辆控制技术领域，特别是涉及一种供能控制方法、装置及混合动力车辆。The present invention relates to the technical field of rail vehicle control, and in particular to an energy supply control method, device and hybrid vehicle.

背景技术Background technique

作为轨道交通领域的主要车型之一，混合动力车辆用来供能的主电源通常包括内燃动力包和储能电源，对应的，实际应用中车辆的供能模式通常包括纯内燃模式、纯储能电源模式以及混合动力模式，其中，储能电源包含的能量较低，通常仅在短距离调车、出入库以及进出站台时使用，或者在混合动力模式下内燃动力包的最大输出功率仍达不到要求时进行能量补足；内燃动力包作为纯内燃模式的唯一动力以及混合动力模式中的主电源，通常作为对整车功率需求的主要响应模块。As one of the main models in the field of rail transit, the main power supply used by hybrid vehicles usually includes internal combustion power packs and energy storage power supplies. Correspondingly, the energy supply modes of vehicles in actual applications usually include pure internal combustion mode and pure energy storage. Power mode and hybrid power mode, in which the energy storage power supply contains low energy and is usually only used for short-distance shunting, entering and exiting the warehouse, and entering and exiting the platform, or the maximum output power of the internal combustion power pack in hybrid mode still does not reach Energy is supplemented when required; the internal combustion power pack serves as the only power in pure internal combustion mode and the main power supply in hybrid mode, and is usually the main response module to the vehicle's power demand.

当前的混合动力车辆在启动时，通常工作在混合动力模式下，或者是纯内燃模式下，但无论处于哪种模式，均主要依靠内燃动力包的输出转速的提升，实现整车牵引功率的提升而达到启动功率要求，达到目标运行速度。但是内燃动力包的响应很慢，即受限于内燃动力包中的柴油机化学能转化为电能的工作原理，整车需要逐步地发送转速需求，以将内燃动力包从最低怠速逐步地、缓慢地加速至整车所需转速，以避免憋停，但这也导致内燃动力包的响应时长通常较久，且对应的启动加速度也较小；此外，对于包括车辆高速平稳性测试在内的车辆试验而言，较小的启动加速度也对应着更长的试验线路才可达到目标运转速度。可见，现有技术中的启动方式对于载客运行的地铁、动车组等存在快速启动需求的车辆来说，响应时间过长，无法满足其较大的启动加速度的需求，且对于试验线路有限的主机厂或试验单位，无法正常进行试验。 When current hybrid vehicles are started, they usually work in hybrid mode or pure internal combustion mode, but no matter which mode they are in, they mainly rely on the increase in the output speed of the internal combustion power package to increase the traction power of the entire vehicle. And reach the starting power requirement and reach the target operating speed. However, the response of the internal combustion power package is very slow, that is, limited by the working principle of converting the chemical energy of the diesel engine into electrical energy in the internal combustion power package, the vehicle needs to gradually send speed requirements to gradually and slowly increase the internal combustion power package from the lowest idle speed. Accelerate to the required speed of the vehicle to avoid stalling, but this also results in the response time of the internal combustion power package being usually longer, and the corresponding starting acceleration is also smaller; in addition, for vehicle tests including vehicle high-speed stability testing Generally speaking, a smaller starting acceleration also corresponds to a longer test line to reach the target operating speed. It can be seen that the response time of the starting method in the existing technology is too long for passenger-carrying subways, EMUs and other vehicles that need to start quickly, and cannot meet their large starting acceleration requirements, and for limited test lines, the response time is too long. The OEM or test unit cannot conduct tests normally.

因此，如何寻找一种有效地方式实现混合动力车辆的按需求启动是当前亟待解决的问题。Therefore, how to find an effective way to realize on-demand starting of hybrid vehicles is an urgent problem that needs to be solved.

请参照图1，图1为本发明提供的一种供能控制方法的流程图。Please refer to Figure 1, which is a flow chart of an energy supply control method provided by the present invention.

本实施例中，混合动力车辆，相较于受电弓或第三轨受流作为主电源 的列车，可以在电气化及非电气化线路通行，相较于纯内燃的车辆，更加绿色、环保及节能，但是混合动力车辆目前的能量控制方式均较为粗放，只能发挥基本功能，具体的，混合动力车辆无论是工作在混合动力模式下，还是纯内燃模式下，本质上均是依靠内燃动力包的输出转速的提升，实现整车牵引功率的提升。但是内燃动力包的响应很慢，其加速过程为从最低怠速逐步地、缓慢地加速至整车所需转速，导致内燃动力包的响应时长通常较久，且对应的启动加速度也较小；此外，对于包括车辆高速平稳性测试在内的车辆试验而言，较小的启动加速度也对应着更长的试验线路，因此，现有技术中的启动方式对于存在快速启动需求的车辆来说，响应时间过长，无法满足其较大的启动加速度的需求，且对于试验线路有限的主机厂或试验单位，无法正常进行试验。为解决上述技术问题，本申请提供了一种供能控制方法，应用于混合动力车辆，可以实现以较大的启动加速度实现车辆的快速启动。In this embodiment, the hybrid vehicle uses the pantograph or the third rail as the main power source. The trains can travel on electrified and non-electrified lines. Compared with pure internal combustion vehicles, they are more green, environmentally friendly and energy-saving. However, the current energy control methods of hybrid vehicles are relatively extensive and can only perform basic functions. Specifically, hybrid vehicles Whether a powered vehicle operates in hybrid mode or pure internal combustion mode, it essentially relies on the increase in output speed of the internal combustion power package to achieve an increase in vehicle traction power. However, the response of the internal combustion power package is very slow, and its acceleration process is to gradually and slowly accelerate from the lowest idle speed to the required speed of the vehicle. As a result, the response time of the internal combustion power package is usually longer, and the corresponding starting acceleration is also smaller; in addition, , for vehicle tests including vehicle high-speed stability testing, smaller starting acceleration also corresponds to longer test lines. Therefore, the starting method in the existing technology is responsive to vehicles with rapid starting requirements. The time is too long to meet the demand for large starting acceleration, and for OEMs or test units with limited test lines, the test cannot be carried out normally. In order to solve the above technical problems, this application provides an energy supply control method, which is applied to hybrid vehicles and can achieve rapid starting of the vehicle with a large starting acceleration.

The hybrid vehicle includes a rectifier module, an internal combustion power pack and an energy storage module. The input end of the rectifier module is connected to the output end of the internal combustion power pack, and the output end of the rectifier module is connected to the energy storage module. The output end is connected to the load. The energy supply control method includes:

S11：在确定存在快速启动需求时，基于混合动力车辆的当前运行速度确定混合动力车辆的第一功率需求；S11: When it is determined that a quick start requirement exists, determine the first power requirement of the hybrid vehicle based on the current operating speed of the hybrid vehicle;

具体的，该混合动力车辆包括但不限于各种混合动力列车、地铁以及动车组等；且该供能控制方法具体可应用与该混合动力车辆中的TCMS(Train Control and Management System，列车管理控制***)。Specifically, the hybrid vehicle includes but is not limited to various hybrid trains, subways, EMUs, etc.; and the energy supply control method can be specifically applied to the TCMS (Train Control and Management System) in the hybrid vehicle. system).

需要说明的是，请参照图2，图2为本申请提供的一种混合动力车辆的结构示意图，可以理解的是，图2中受限于图片展示篇幅，重点阐述储能模块、内燃动力包及整流模块之间的连接方式，但具体的，储能模块、内燃动力包及整流模块均与TCMS通讯连接，以实现本申请中的控制逻辑，在此不作特别的说明；储能模块即为混合动力车辆中的储能电源，整流模块的输出正端与储能模块的输出正端连接，整流模块的输出负端与储能模块的输出负端连接，图2中，K01和K02为与储能模块对应的主接触器，K03 和K04为与整流模块对应的主接触器；这里的负载包括但不限于牵引变流器及空调等各种用电负载，此处不作特别的限定。It should be noted that please refer to Figure 2, which is a schematic structural diagram of a hybrid vehicle provided by the present application. It can be understood that due to the limitation of the picture display space, Figure 2 focuses on the energy storage module and internal combustion power package. and the connection method between the rectifier modules, but specifically, the energy storage module, internal combustion power pack and rectifier module are all connected to the TCMS communication to realize the control logic in this application, and there will be no special explanation here; the energy storage module is In the energy storage power supply in hybrid vehicles, the positive output terminal of the rectifier module is connected to the positive output terminal of the energy storage module, and the negative output terminal of the rectifier module is connected to the negative output terminal of the energy storage module. In Figure 2, K01 and K02 are Main contactor corresponding to the energy storage module, K03 and K04 are the main contactors corresponding to the rectifier module; the loads here include but are not limited to various electrical loads such as traction converters and air conditioners, and are not specifically limited here.

更具体的，在S11步骤之前，还可以包括：混合动力车辆激活后，储能模块、内燃动力包等混合动力车辆上的各部件开始自检，当然，也可以确定当前的网络通讯是否正常以确保指令及信息的可靠传递，并将所有的检测结果发送给TCMS，在确定检测全部通过之后(具体的，可进一步在HMI屏上显示可正常启动字样，以便于司机掌握情况以进行下一步动作)，司机启动内燃动力包，同时，TCMS控制图2中的K01和K02、K03和K04均闭合，以使整流模块、储能模块均可投入使用，为后续的控制逻辑做准备(具体的，司机可以按压引擎启动按钮启动内燃动力包，此时内燃动力包的输出转速为最低怠速，此外，可以控制整流模块的输出电压，以达到与储能模块的输出电压相近的电压值，实现控制储能模块处于不充电且不放电状态)。More specifically, before step S11, it can also include: after the hybrid vehicle is activated, various components on the hybrid vehicle such as the energy storage module and the internal combustion power pack start self-checking. Of course, it can also be determined whether the current network communication is normal. Ensure the reliable transmission of instructions and information, and send all test results to TCMS. After confirming that all tests have passed (specifically, the words "can be started normally" can be further displayed on the HMI screen, so that the driver can grasp the situation and take the next step. ), the driver starts the internal combustion power package. At the same time, K01 and K02, K03 and K04 in the TCMS control diagram 2 are all closed, so that the rectifier module and energy storage module can be put into use to prepare for the subsequent control logic (specifically, The driver can press the engine start button to start the internal combustion power pack. At this time, the output speed of the internal combustion power pack is the minimum idle speed. In addition, the output voltage of the rectifier module can be controlled to reach a voltage value close to the output voltage of the energy storage module to achieve controlled storage. The module is in a non-charging and non-discharging state).

确定存在快速启动需求的具体方式包括但不限于为：司机根据实际情况，在HMI屏上选择启动模式(该启动模式具体可包括动力模式和常规模式)时，选择表征实现快速启动的动力模式，即确定存在快速启动需求。于是，确定混合动力车辆当前的第一功率需求(具体的，可以在TCMS中设置列车功率需求模块，用于计算混合动力车辆在不同时刻的功率需求)。可以理解的是，动力模式意味着更高的启动加速度，可满足地铁、动车组或其他载客车辆的快速启动的需求。Specific ways to determine the need for quick start include but are not limited to: when the driver selects the start mode on the HMI screen (the start mode may specifically include power mode and regular mode) according to the actual situation, select the power mode that represents a quick start, That is, it is determined that there is a need for quick start. Therefore, the current first power demand of the hybrid vehicle is determined (specifically, a train power demand module can be set in TCMS to calculate the power demand of the hybrid vehicle at different times). It is understandable that the power mode means higher starting acceleration, which can meet the needs of quick starting of subways, EMUs or other passenger vehicles.

S12：控制内燃动力包的输出转速为最低怠速；S12: Control the output speed of the internal combustion power package to the lowest idle speed;

具体的，可以在TCMS中设置功率分配模块，用于根据列车功率需求模块计算的混合动力车辆在不同时刻的功率需求，向内燃动力包及整流模块发送对应控制指令。内燃动力包中包括CPU(Central Processing Unit，中央控制器)及柴油机，柴油机的转速即为所述内燃动力包的输出转速，更具体的，内燃动力包的怠速包括多档，假定为1至8档，则此处的最低怠速为1档；于是，TCMS中的所述功率分配模块向所述内燃动力包发送第一控制指令(具体为将该控制指令发送给所述CPU，由CPU进一步控制柴油机的转速)，以使得内燃动力包的输出转速保持在所述最低怠速即可。 Specifically, a power distribution module can be set up in TCMS to send corresponding control instructions to the internal combustion power pack and rectifier module according to the power requirements of the hybrid vehicle at different times calculated by the train power demand module. The internal combustion power package includes a CPU (Central Processing Unit, central controller) and a diesel engine. The rotation speed of the diesel engine is the output speed of the internal combustion power package. More specifically, the idle speed of the internal combustion power package includes multiple gears, which are assumed to be 1 to 8. gear, then the lowest idle speed here is gear 1; therefore, the power distribution module in TCMS sends a first control instruction to the internal combustion power package (specifically, the control instruction is sent to the CPU, which is further controlled by the CPU. The speed of the diesel engine), so that the output speed of the internal combustion power package is maintained at the minimum idle speed.

S13：控制整流模块的输出电压，以控制储能模块的输出功率为第一功率需求与内燃动力包保持最低怠速时对应的输出功率的差值。S13: Control the output voltage of the rectifier module to control the output power of the energy storage module to be the difference between the first power demand and the output power corresponding to when the internal combustion power pack maintains the lowest idle speed.

具体的，S12步骤和S13步骤可以同步进行；TCMS中的所述功率分配模块向所述内燃动力包发送第二控制指令，以控制所述整流模块的输出电压，进而控制储能模块的输出功率。更具体的，请参照图2，由于内燃动力包输出的为三相电，因此该整流模块内部可以包括AC-DC转换器(Alternating Current-Direct current，交流-直流转换器)以及DC-DC转换器(Direct current-Direct current，直流-直流转换器)，进而S13步骤本质上为控制整流模块的输出电压在预设合理调节范围内低于储能模块的输出电压，以使得储能模块处于放电状态，即实现功率输出，通过调控整流模块的输出电压，可以调控储能模块的输出功率，以实现控制储能模块的输出功率为第一功率需求与内燃动力包保持最低怠速时对应的输出功率的差值。Specifically, steps S12 and S13 can be performed simultaneously; the power distribution module in the TCMS sends a second control instruction to the internal combustion power package to control the output voltage of the rectifier module and thereby control the output power of the energy storage module. . More specifically, please refer to Figure 2. Since the internal combustion power pack outputs three-phase electricity, the rectifier module can include an AC-DC converter (Alternating Current-Direct current, AC-DC converter) and a DC-DC conversion. (Direct current-Direct current, DC-DC converter), and then step S13 is essentially to control the output voltage of the rectifier module to be lower than the output voltage of the energy storage module within a preset reasonable adjustment range, so that the energy storage module is in discharge state, that is, to achieve power output. By adjusting the output voltage of the rectifier module, the output power of the energy storage module can be adjusted to control the output power of the energy storage module to the output power corresponding to the first power demand and the internal combustion power pack maintaining the lowest idle speed. difference.

需要说明的是，在上述实施例中所述的动力模式下，由于随着时间推移，混合动力车辆的当前运行速度一直处于变化之中，因此对应的第一功率需求本质上也一直在实时变化，因此，S11步骤中确定所述第一功率需求的步骤可以实时进行，或者以较短的周期进行。It should be noted that in the power mode described in the above embodiment, since the current operating speed of the hybrid vehicle is always changing as time goes by, the corresponding first power demand is essentially always changing in real time. , therefore, the step of determining the first power requirement in step S11 can be performed in real time or in a shorter period.

至此，按照上述实施例的步骤可知，该动力模式下，内燃动力包的输出转速始终处于最低怠速，因此所述第一功率需求的变化主要依靠储能模块的输出功率进行调节补足，基于储能模块具有快速放电、释放大电流的特性，可快速放电实现自身的输出功率的调整，以为混合动力车辆提供足够的牵引电流，此时储能模块为主要输出源，保证了对第一功率需求的变化的及时响应。At this point, according to the steps of the above embodiment, it can be seen that in this power mode, the output speed of the internal combustion power package is always at the lowest idle speed. Therefore, the change in the first power demand mainly relies on the output power of the energy storage module to adjust and supplement. Based on the energy storage The module has the characteristics of rapid discharge and large current release. It can quickly discharge to adjust its own output power to provide sufficient traction current for hybrid vehicles. At this time, the energy storage module is the main output source, ensuring that the first power demand is met. Timely response to changes.

可以理解的是，本申请中所述的混合动力车辆当然也可以依靠对应的控制逻辑实现纯内燃模式、纯储能模式以及现有技术中的混合动力模式，依靠现有技术中的方式进行对应控制即可，本申请解决的重点在于为包括内燃动力包以及储能电源的地铁、动车组等，提供快速启动的电路结构及对应控制方式。It can be understood that the hybrid vehicle described in this application can of course also rely on the corresponding control logic to implement pure internal combustion mode, pure energy storage mode, and the hybrid mode in the prior art, and rely on the methods in the prior art to respond. The focus of this application is to provide a quick start circuit structure and corresponding control method for subways, EMUs, etc. that include internal combustion power packs and energy storage power sources.

综上，本申请提供了一种供能控制方法，在确定存在快速启动需求时， 确定混合动力车辆的第一功率需求；随后，基于储能模块具有快速放电特性，仅控制内燃动力包的输出转速为最低怠速，以实现最低怠速对应的功率输出，剩余部分均由储能模块提供，即通过控制整流模块的输出电压，以控制储能模块的输出功率为第一功率需求与内燃动力包保持最低怠速时对应的输出功率的差值。相较于现有技术，可以更快速地达到第一功率需求，真正依靠内燃动力包配合储能模块，实现了混合动力车辆的快速启动；且对应的启动加速度也更高，对于车辆试验而言，更高的启动加速度对应于更短的试验线路，保证了试验的正常进行。In summary, this application provides an energy supply control method. When it is determined that there is a need for quick start, Determine the first power requirement of the hybrid vehicle; then, based on the rapid discharge characteristics of the energy storage module, only the output speed of the internal combustion power package is controlled to the minimum idle speed to achieve the power output corresponding to the minimum idle speed, and the remaining part is provided by the energy storage module , that is, by controlling the output voltage of the rectifier module, the output power of the energy storage module is controlled to be the difference between the first power demand and the corresponding output power when the internal combustion power pack maintains the lowest idle speed. Compared with the existing technology, the first power demand can be reached more quickly. It truly relies on the internal combustion power package and the energy storage module to realize the quick start of the hybrid vehicle; and the corresponding starting acceleration is also higher, which is suitable for vehicle testing. , a higher starting acceleration corresponds to a shorter test line, ensuring the normal conduct of the test.

在上述实施例的基础上：Based on the above embodiments:

作为一种优选的实施例，基于混合动力车辆的当前运行速度确定混合动力车辆的第一功率需求之前，还包括：As a preferred embodiment, before determining the first power demand of the hybrid vehicle based on the current operating speed of the hybrid vehicle, the method further includes:

获取混合动力车辆当前行驶线路的限速信息、辅助功能模块的功率信息及与混合动力车辆中司控器当前牵引极位对应的极位标识信息；Obtain the speed limit information of the hybrid vehicle's current driving route, the power information of the auxiliary function module, and the pole identification information corresponding to the current traction pole position of the driver's controller in the hybrid vehicle;

基于混合动力车辆的当前运行速度确定混合动力车辆的第一功率需求，包括：Determine the hybrid vehicle's first power requirement based on the hybrid vehicle's current operating speed, including:

基于混合动力车辆的当前运行速度、限速信息、功率信息以及极位标识信息，确定混合动力车辆的第一功率需求。Based on the current operating speed, speed limit information, power information and extreme position identification information of the hybrid vehicle, the first power demand of the hybrid vehicle is determined.

本实施例中，给出了确定第一功率需求的步骤，具体见上述所述，此处不再赘述。还需要说明的是，所述限速信息本质上与混合动力车辆当前行驶线路的限速情况(即线路条件)有关，比如有的线路限速为80km/h，有的线路限速为90km/h，因此确定第一功率需求时需要考虑到该情况；所述辅助功能模块的功率信息表征了包括如空调等在内的用电设备的所需功率情况。In this embodiment, the steps for determining the first power requirement are given. The details are as described above and will not be described again here. It should also be noted that the speed limit information is essentially related to the speed limit of the route where the hybrid vehicle is currently traveling (i.e., route conditions). For example, some routes have a speed limit of 80km/h, and some routes have a speed limit of 90km/h. h, therefore this situation needs to be taken into consideration when determining the first power demand; the power information of the auxiliary function module represents the required power situation of electrical equipment including air conditioners, etc.

可以理解的是，第一功率需求还可以基于其他条件信息确定，在此不作特别的限定，根据实际需求设定即可。It can be understood that the first power requirement can also be determined based on other condition information, which is not particularly limited here and can be set according to actual requirements.

作为一种优选的实施例，还包括：As a preferred embodiment, it also includes:

在确定存在常规启动需求时，基于混合动力车辆的当前运行速度确定混合动力车辆的第二功率需求； determining a second power requirement of the hybrid vehicle based on a current operating speed of the hybrid vehicle when it is determined that a conventional starting requirement exists;

判断第二功率需求是否不低于内燃动力包的最大发出功率；Determine whether the second power demand is not less than the maximum output power of the internal combustion power package;

若否，基于预设转速-功率对应关系，分第一预设次数地向内燃动力包发送第一调速指令，直至内燃动力包的输出功率达到第二功率需求。If not, based on the preset rotation speed-power correspondence relationship, the first speed adjustment command is sent to the internal combustion power package a first preset number of times until the output power of the internal combustion power package reaches the second power requirement.

本实施例中，发明人进一步考虑到，司机根据实际情况，在HMI屏上选择启动模式时，还可能选择表征实现正常启动的常规模式，即确定存在常规启动需求，以期实现平缓加速启动。于是，基于混合动力车辆的当前运行速度确定混合动力车辆的第二功率需求(具体的，该第二功率需求可以为所述列车功率需求模块计算得到，更具体的，可以为基于混合动力车辆的当前运行速度、混合动力车辆当前行驶线路的限速信息、辅助功能模块的功率信息以及混合动力车辆中司控器当前牵引极位对应的极位标识信息，确定混合动力车辆的第二功率需求)，判断第二功率需求是否不低于内燃动力包的最大发出功率，其中，所述最大发出功率为内燃动力包的输出转速为额定转速时所能发出的最大功率；In this embodiment, the inventor further considers that the driver may also select the conventional mode representing normal start-up when selecting the start-up mode on the HMI screen according to the actual situation, that is, determine the existence of conventional start-up requirements in order to achieve smooth acceleration start-up. Therefore, the second power requirement of the hybrid vehicle is determined based on the current operating speed of the hybrid vehicle (specifically, the second power requirement can be calculated by the train power requirement module, and more specifically, the second power requirement of the hybrid vehicle can be determined based on the current operating speed of the hybrid vehicle, the speed limit information of the current driving route of the hybrid vehicle, the power information of the auxiliary function module, and the pole position identification information corresponding to the current traction pole position of the driver controller in the hybrid vehicle), and judge whether the second power requirement is not less than the maximum output power of the internal combustion power pack, wherein the maximum output power is the maximum power that can be output when the output speed of the internal combustion power pack is the rated speed;

若否，考虑到内燃动力包的加速过程不可以直接给到第二功率需求对应的目标转速，因此，基于预设转速-功率对应关系，分第一预设次数地向内燃动力包发送第一调速指令(具体的，可以为所述功率分配模块发送至所述内燃动力包中的CPU，再由CPU进一步控制柴油机的转速以实现内燃动力包的输出转速的调节，进而实现内燃动力包的输出功率的调节)，直至内燃动力包的输出功率达到第二功率需求，此时，由于第二功率需求低于内燃动力包的最大发出功率，因此，由内燃动力包本身进行供能即可。If not, considering that the acceleration process of the internal combustion power pack cannot directly give the target speed corresponding to the second power demand, therefore, based on the preset speed-power correspondence relationship, the first speed is sent to the internal combustion power pack a first preset number of times. The speed regulation command (specifically, the power distribution module can be sent to the CPU in the internal combustion power package, and then the CPU further controls the rotation speed of the diesel engine to adjust the output speed of the internal combustion power package, thereby realizing the output speed of the internal combustion power package. Adjustment of the output power) until the output power of the internal combustion power pack reaches the second power demand. At this time, since the second power demand is lower than the maximum output power of the internal combustion power pack, the internal combustion power pack itself can provide energy.

还需要说明的是，在此常规模式下，内燃动力包的输出转速始终处于变化中，考虑到内燃动力包转速响应滞后特性，设置第一预设次数进行控制指令发送的目的在于，避免直接将目标转速对应的功率需求指令发送后，内燃动力包当前的输出转速无法满足所述功率需求指令对应的功率需求而出现憋停，此外，第一预设次数根据实际需求设定即可。It should also be noted that in this normal mode, the output speed of the internal combustion power pack is always changing. Considering the hysteresis characteristic of the speed response of the internal combustion power pack, the purpose of setting the first preset number of times to send control instructions is to avoid directly After the power demand command corresponding to the target speed is sent, the current output speed of the internal combustion power package cannot meet the power demand corresponding to the power demand command and stalls. In addition, the first preset number can be set according to actual demand.

可见，通过上述方式可以为司机提供可供选择的更多的启动方式，便于实际应用。It can be seen that through the above method, the driver can be provided with more starting methods to choose from, which facilitates practical application.

作为一种优选的实施例，在判定第二功率需求高于内燃动力包的最大发出功率时，包括： As a preferred embodiment, when determining that the second power demand is higher than the maximum output power of the internal combustion power package, the following steps are included:

基于预设转速-功率对应关系，分第二预设次数地向内燃动力包发送第二调速指令，以使内燃动力包的输出功率达到最大发出功率；Based on the preset rotation speed-power correspondence relationship, send a second speed adjustment instruction to the internal combustion power pack a second preset number of times so that the output power of the internal combustion power pack reaches the maximum output power;

控制整流模块的输出电压，以控制储能模块的输出功率为第二功率需求与最大发出功率的差值。The output voltage of the rectifier module is controlled to control the output power of the energy storage module to be the difference between the second power demand and the maximum generated power.

本实施例中，给出了在判定第二功率需求高于内燃动力包的最大发出功率时的处理步骤，具体见上述所述。需要说明的是，此种情况下，说明当前内燃动力包不足以提供当前整车的牵引功率，因此，基于预设转速-功率对应关系，分第二预设次数地向内燃动力包发送第二调速指令(具体的，可以为所述功率分配模块发送至所述内燃动力包中的CPU，再由CPU进一步控制柴油机的转速以实现内燃动力包的输出转速的调节，进而实现内燃动力包的输出功率的调节)，以使内燃动力包的输出功率达到最大发出功率；同时，控制整流模块的输出电压，以控制储能模块的输出功率为第二功率需求与最大发出功率的差值。In this embodiment, the processing steps are provided when it is determined that the second power demand is higher than the maximum output power of the internal combustion power package. The details are as described above. It should be noted that in this case, it means that the current internal combustion power package is not enough to provide the current traction power of the entire vehicle. Therefore, based on the preset speed-power correspondence relationship, the second power package is sent to the internal combustion power package a second preset number of times. The speed regulation command (specifically, the power distribution module can be sent to the CPU in the internal combustion power package, and then the CPU further controls the rotation speed of the diesel engine to adjust the output speed of the internal combustion power package, thereby realizing the output speed of the internal combustion power package. Adjustment of output power), so that the output power of the internal combustion power package reaches the maximum output power; at the same time, the output voltage of the rectifier module is controlled to control the output power of the energy storage module to be the difference between the second power demand and the maximum output power.

需要说明的是，更具体的，控制整流模块的输出电压在第三预设调节范围内低于储能模块的输出电压，以保证储能模块处于放电状态，即功率输出状态，且其输出功率为第二功率需求与最大发出功率的差值，从而，实现了储能模块配合内燃动力包实现整车牵引功率的提供。It should be noted that, more specifically, the output voltage of the rectifier module is controlled to be lower than the output voltage of the energy storage module within the third preset adjustment range to ensure that the energy storage module is in a discharge state, that is, a power output state, and its output power is the difference between the second power demand and the maximum output power, thereby realizing the energy storage module to cooperate with the internal combustion power package to provide the traction power of the entire vehicle.

还需要说明的是，第二预设次数根据实际需求设定即可。It should also be noted that the second preset number of times can be set according to actual needs.

作为一种优选的实施例，还包括：As a preferred embodiment, it also includes:

判断混合动力车辆的当前运行速度是否达到预设最低功耗判定门限条件；Determine whether the current operating speed of the hybrid vehicle reaches the preset minimum power consumption determination threshold condition;

若达到预设最低功耗判定门限条件，基于混合动力车辆的当前运行速度确定混合动力车辆的第四功率需求；If the preset minimum power consumption determination threshold condition is reached, determine the fourth power demand of the hybrid vehicle based on the current operating speed of the hybrid vehicle;

基于第四功率需求、内燃动力包的最佳输出功率与储能模块的剩余电量，判断混合动力车辆是否具备工作在预设最低油耗模式的资格，其中，最佳输出功率与内燃动力包的预设最佳油耗转速对应；Based on the fourth power requirement, the optimal output power of the internal combustion power package and the remaining power of the energy storage module, it is determined whether the hybrid vehicle is qualified to operate in the preset minimum fuel consumption mode. Among them, the optimal output power and the preset value of the internal combustion power package are Assume that the optimal fuel consumption speed corresponds to;

若判定具备资格，基于预设最低油耗控制策略，控制内燃动力包及储能模块的输出功率。If it is determined to be qualified, the output power of the internal combustion power pack and energy storage module will be controlled based on the preset minimum fuel consumption control strategy.

本实施例中，发明人进一步考虑到混合动力车辆的整车能耗还有很大 的优化空间，因此提供了一种预设最低油耗控制策略及对应控制逻辑，以使整车的能耗达到最低状态进行运行，降低运营成本。In this embodiment, the inventor further considered that the overall energy consumption of the hybrid vehicle is still very large. There is room for optimization, so a preset minimum fuel consumption control strategy and corresponding control logic are provided to enable the vehicle to operate at the lowest energy consumption and reduce operating costs.

预先设置了内燃动力包的预设最佳油耗转速，该预设最佳油耗转速对应的功率即为所述最佳输出功率。可以理解的是，所述预设最佳油耗转速包括在混合动力车辆的各个档位的怠速之内。基于储能模块的剩余电量可确定当前剩余电量对应的最大输出功率，于是，若达到预设最低功耗判定门限条件，基于混合动力车辆的当前运行速度确定混合动力车辆的第四功率需求(具体的，该步骤为基于混合动力车辆的当前运行速度、与混合动力车辆中司控器当前牵引极位对应的极位标识信息以及混合动力车辆当前行驶线路的限速信息(如最大允许速度)，确定混合动力车辆的第四功率需求)。A preset optimal fuel consumption speed of the internal combustion power package is preset, and the power corresponding to the preset optimal fuel consumption speed is the optimal output power. It can be understood that the preset optimal fuel consumption speed is included in the idle speed of each gear of the hybrid vehicle. The maximum output power corresponding to the current remaining power can be determined based on the remaining power of the energy storage module. Therefore, if the preset minimum power consumption determination threshold condition is reached, the fourth power requirement of the hybrid vehicle is determined based on the current operating speed of the hybrid vehicle (specifically , this step is based on the current operating speed of the hybrid vehicle, the pole identification information corresponding to the current traction pole position of the controller in the hybrid vehicle, and the speed limit information (such as the maximum allowable speed) of the current driving route of the hybrid vehicle, Determine the fourth power requirement of a hybrid vehicle).

进而，若判定所述内燃动力包的最佳输出功率与所述储能模块的剩余电量对应的最大输出功率能够满足第四功率需求，则判定其具备工作在预设最低油耗模式的资格。Furthermore, if it is determined that the optimal output power of the internal combustion power package and the maximum output power corresponding to the remaining power of the energy storage module can meet the fourth power requirement, it is determined that it is qualified to work in the preset minimum fuel consumption mode.

若判定所述内燃动力包的最佳输出功率与所述储能模块的剩余电量对应的最大输出功率不能够满足第四功率需求，则判定其不具备工作在预设最低油耗模式的资格；可以理解的是，此时控制内燃动力包及储能模块保持启动时对应的控制策略输出以实现供能即可，即若启动时按照上述实施例中所述的动力模式进行控制则保持该控制，或者若启动时按照所述常规模式进行控制则保持该控制，并继续保持对混合动力车辆的当前运行速度是否达到预设最低功耗判定门限条件的判断。If it is determined that the optimal output power of the internal combustion power package and the maximum output power corresponding to the remaining power of the energy storage module cannot meet the fourth power requirement, it is determined that it is not qualified to work in the preset minimum fuel consumption mode; yes It is understood that at this time, it is sufficient to control the internal combustion power package and the energy storage module to maintain the corresponding control strategy output at startup to achieve energy supply. That is, if the control is performed according to the power mode described in the above embodiment at startup, the control is maintained. Or if the control is performed according to the normal mode at startup, the control is maintained, and the judgment of whether the current operating speed of the hybrid vehicle reaches the preset minimum power consumption determination threshold condition is continued.

还需要说明的是，在判定混合动力车辆的当前运行速度未达到预设最低功耗判定门限条件时，同样可以保持控制内燃动力包及储能模块保持启动时对应的控制策略输出以实现供能即可，并继续保持对混合动力车辆的当前运行速度是否达到预设最低功耗判定门限条件的判断。It should also be noted that when it is determined that the current operating speed of the hybrid vehicle does not reach the preset minimum power consumption determination threshold condition, the corresponding control strategy output when the internal combustion power pack and energy storage module remain activated can also be maintained to achieve energy supply. That's it, and continue to judge whether the current operating speed of the hybrid vehicle reaches the preset minimum power consumption judgment threshold condition.

作为一种优选的实施例，判定混合动力车辆的当前运行速度达到预设最低功耗判定门限条件，包括：As a preferred embodiment, determining that the current operating speed of the hybrid vehicle reaches the preset minimum power consumption determination threshold condition includes:

在确定混合动力车辆处于匀速行驶阶段，和/或，混合动力车辆的当前运行速度与线路最大允许运行速度的差值小于预设速度阈值时，判定混合 动力车辆的当前运行速度达到预设最低功耗判定门限条件。When it is determined that the hybrid vehicle is in the constant speed driving stage, and/or the difference between the current operating speed of the hybrid vehicle and the maximum allowable operating speed of the line is less than the preset speed threshold, it is determined that the hybrid vehicle The current operating speed of the powered vehicle reaches the preset minimum power consumption determination threshold condition.

本实施例中，给出了判定混合动力车辆的当前运行速度达到预设最低功耗判定门限条件的实现逻辑，具体见上述所述，此处不再赘述。需要说明的是，所述预设速度阈值包括但不限于40km/h。In this embodiment, the implementation logic for determining that the current operating speed of the hybrid vehicle reaches the preset minimum power consumption determination threshold condition is provided. The details are as described above and will not be described again here. It should be noted that the preset speed threshold includes but is not limited to 40km/h.

作为一种优选的实施例，基于预设最低油耗控制策略，控制内燃动力包及储能模块的输出功率，包括：As a preferred embodiment, based on the preset minimum fuel consumption control strategy, controlling the output power of the internal combustion power package and energy storage module includes:

控制内燃动力包中的输出转速调整至预设最佳油耗转速，以使内燃动力包的输出功率为最佳输出功率；Control the output speed of the internal combustion power package to adjust to the preset optimal fuel consumption speed, so that the output power of the internal combustion power package is the optimal output power;

控制整流模块的输出电压，以控制整流模块的输出电压与储能模块的输出电压的差值处于预设电压容忍范围内；Control the output voltage of the rectifier module to control the difference between the output voltage of the rectifier module and the output voltage of the energy storage module to be within a preset voltage tolerance range;

基于混合动力车辆的当前运行速度确定混合动力车辆的第三功率需求；determining a tertiary power requirement of the hybrid vehicle based on a current operating speed of the hybrid vehicle;

判断最佳输出功率是否大于第三功率需求；Determine whether the optimal output power is greater than the third power requirement;

若是，控制整流模块的输出电压在第一预设调节范围内高于储能模块的输出电压，以使储能模块储能。If so, the output voltage of the rectifier module is controlled to be higher than the output voltage of the energy storage module within the first preset adjustment range, so that the energy storage module stores energy.

本实施例中，给出了基于预设最低油耗控制策略，控制内燃动力包及储能模块的输出功率的控制逻辑，具体见上述所述，此处不再赘述。需要说明的是，控制内燃动力包中的输出转速调整至所述预设最佳油耗转速的过程可以为：基于预设转速-功率对应关系，分第三预设次数地向内燃动力包发送第三调速指令，以使内燃动力包的输出转速达到预设最佳油耗转速，以免内燃动力包控制过程中出现憋停。In this embodiment, the control logic for controlling the output power of the internal combustion power package and the energy storage module based on the preset minimum fuel consumption control strategy is given. The details are as described above and will not be described again here. It should be noted that the process of controlling the output speed in the internal combustion power package to adjust to the preset optimum fuel consumption speed may be: based on the preset speed-power correspondence relationship, sending the third speed to the internal combustion power package a third preset number of times. Three speed adjustment instructions are used to make the output speed of the internal combustion power package reach the preset optimal fuel consumption speed to avoid stalling during the control process of the internal combustion power package.

所述控制整流模块的输出电压与储能模块的输出电压的差值处于预设电压容忍范围内，这一步骤本质上为控制储能模块预先保持在不充电且不放电的状态，因此，需要控制整流模块的输出电压与储能模块的输出电压处于上述所述的相近状态，为后续执行逻辑做准备。The difference between the output voltage of the control rectifier module and the output voltage of the energy storage module is within the preset voltage tolerance range. This step is essentially to control the energy storage module to maintain a non-charging and non-discharging state in advance. Therefore, it is necessary to The output voltage of the rectifier module and the output voltage of the energy storage module are controlled to be in a similar state as described above to prepare for subsequent logic execution.

由于混合动力车辆的当前运行速度始终处于变化中，因此确定当前混合动力车辆的第三功率需求(更具体的，基于混合动力车辆的当前运行速度、与混合动力车辆中司控器当前牵引极位对应的极位标识信息以及混合动力车辆当前行驶线路的限速信息，确定混合动力车辆的第三功率需求)。 Since the current operating speed of the hybrid vehicle is always changing, the third power requirement of the current hybrid vehicle is determined (more specifically, based on the current operating speed of the hybrid vehicle, and the current traction extreme position of the driver controller in the hybrid vehicle The corresponding extreme position identification information and the speed limit information of the hybrid vehicle's current driving route determine the third power demand of the hybrid vehicle).

若所述最佳输出功率大于第三功率需求，说明内燃动力包即可实现对于整车牵引需求，且还有余量。因此，控制整流模块的输出电压在第一预设调节范围内高于储能模块的输出电压，此时储能模块处于充电状态而实现储能，保证了储能模块维持在高储能状态。可以理解的是，此时整流模块的输出电压与储能模块的输出电压的电压差值，本质上与所述内燃动力包的输出功率与所述第三功率需求之间的差值成正比；而所述第一预设调节范围的设置原因在于，整流模块的输出电压应在一定范围内高于储能模块的输出电压，否则反而影响储能模块的工作，第一预设调节范围包括但不限于60V，在此不作特别的限定，根据实际需求而定即可。If the optimal output power is greater than the third power requirement, it means that the internal combustion power package can meet the traction requirements of the entire vehicle, and there is still a margin. Therefore, the output voltage of the rectifier module is controlled to be higher than the output voltage of the energy storage module within the first preset adjustment range. At this time, the energy storage module is in a charging state and energy storage is realized, ensuring that the energy storage module is maintained in a high energy storage state. It can be understood that at this time, the voltage difference between the output voltage of the rectifier module and the output voltage of the energy storage module is essentially proportional to the difference between the output power of the internal combustion power package and the third power demand; The reason for setting the first preset adjustment range is that the output voltage of the rectifier module should be higher than the output voltage of the energy storage module within a certain range, otherwise it will affect the operation of the energy storage module. The first preset adjustment range includes but Not limited to 60V, no special restrictions are made here, it can be determined according to actual needs.

需要说明的是，在预设最低油耗控制策略下，内燃动力包的输出转速始终处于所述预设最佳油耗转速。It should be noted that under the preset minimum fuel consumption control strategy, the output speed of the internal combustion power package is always at the preset optimal fuel consumption speed.

作为一种优选的实施例，在判定最佳输出功率小于第三功率需求时，包括：As a preferred embodiment, when determining that the optimal output power is less than the third power requirement, it includes:

判断储能模块的剩余电量对应的最大输出功率与最佳输出功率之和是否大于第三功率需求；Determine whether the sum of the maximum output power and the optimal output power corresponding to the remaining power of the energy storage module is greater than the third power requirement;

若是，控制内燃动力包的输出功率保持在最佳输出功率；If so, control the output power of the internal combustion power package to maintain the optimal output power;

控制整流模块的输出电压在第二预设调节范围内低于储能模块的输出电压，以控制储能模块的输出功率为第三功率需求与最佳功率需求的差值。The output voltage of the rectifier module is controlled to be lower than the output voltage of the energy storage module within the second preset adjustment range, so that the output power of the energy storage module is controlled to be the difference between the third power demand and the optimal power demand.

本实施例中，可以理解的是，第三功率需求随着混合动力车辆的当前运行速度实时在变化，因此在判定最佳输出功率小于第三功率需求时，可进一步判断储能模块的剩余电量对应的最大输出功率与最佳输出功率之和是否大于第三功率需求；In this embodiment, it can be understood that the third power demand changes in real time with the current operating speed of the hybrid vehicle. Therefore, when it is determined that the optimal output power is less than the third power demand, the remaining power of the energy storage module can be further determined. Whether the sum of the corresponding maximum output power and optimal output power is greater than the third power requirement;

若否，则说明当前混合动力车辆已不具备工作在预设最低油耗模式的资格，于是，可以控制内燃动力包及储能模块保持启动时对应的控制策略输出以实现供能即可，即若启动时为按照上述实施例中所述的动力模式进行供能则保持该控制，或者若启动时为按照所述常规模式进行供能则保持该控制，并继续保持对混合动力车辆的当前运行速度是否达到预设最低功耗判定门限条件的判断。If not, it means that the current hybrid vehicle is no longer qualified to work in the preset minimum fuel consumption mode.
