具体实施方式Detailed ways

这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

相关技术中，一般根据用户的意愿使用电池的能量，车辆根据电池管理***发出的电池功率map以及电机控制器发送的故障信息，优先保证车辆电池不出现故障，控制电池的输出功率。即现有的车辆在控制时，根据用户驾驶行为控制电机转速从而控制电池输出能量，在急加速/急减速工况下电池的瞬间输出功率会较大，且通常能量回馈利用率较小，导致实际上电池的电量被浪费。In the related technology, the battery energy is generally used according to the user's wishes. The vehicle prioritizes ensuring that the vehicle battery does not fail and controls the battery output power according to the battery power map sent by the battery management system and the fault information sent by the motor controller. That is, when the existing vehicle is controlled, the motor speed is controlled according to the user's driving behavior to control the battery output energy. Under the condition of rapid acceleration/deceleration, the instantaneous output power of the battery will be large, and the energy feedback utilization rate is usually low, resulting in the actual waste of battery power.

相关技术中，车辆车载导航和高清地图可以用于对地图上已知的路径进行全路段评估。电动汽车可以根据电池的当前温度和电池当前的SOC值从电池的功率map中查询得到当前电池能够提供的最大的放电和被充电的功率。基于车载导航回传的高清地图，本公开提供的解决上述问题的构思为：对车辆将行驶的路径的路况进行分割，根据用户在不同路况下的驾驶习惯以及不同的驾驶模式，控制车辆的行驶速度，从而根据车辆的行驶速度计算出车辆的电机的输出功率和电池输出功率。In the related art, the vehicle's onboard navigation and high-definition maps can be used to evaluate the entire road section of a known path on the map. Electric vehicles can query the maximum discharge and charging power that the current battery can provide from the battery power map based on the current temperature of the battery and the current SOC value of the battery. Based on the high-definition map transmitted back by the on-board navigation, the concept of solving the above problem provided by the present disclosure is: segment the road conditions of the path that the vehicle will travel, control the vehicle's driving speed according to the user's driving habits under different road conditions and different driving modes, and thus calculate the output power of the vehicle's motor and the battery output power according to the vehicle's driving speed.

本公开是基于对大数据的可行性分析，采集的用户数据和高清地图均能回传到车载服务器里对相关的大数据进行拟合和推算，从而在满足用户对车辆控制需求的同时，优化电池电量的使用。The present disclosure is based on the feasibility analysis of big data. The collected user data and high-definition maps can be transmitted back to the vehicle server to fit and calculate the relevant big data, thereby optimizing the use of battery power while meeting the user's needs for vehicle control.

下面结合附图对本公开的实施例进行具体说明。The embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

请参阅图1，图1是根据一示例性实施例示出的一种增加车辆续航里程的方法的流程图，如图1所示，增加车辆续航里程的方法包括：Please refer to FIG. 1 , which is a flow chart of a method for increasing the cruising range of a vehicle according to an exemplary embodiment. As shown in FIG. 1 , the method for increasing the cruising range of a vehicle includes:

S101、获取车辆当前的驾驶模式以及前方路段的路况信息。S101, obtaining the current driving mode of the vehicle and the road condition information of the road ahead.

具体地，车辆当前的驾驶模式包括自动驾驶模式和手动驾驶模式，其中，自动驾驶模式通过车载电脑***实现无人驾驶的智能汽车，自动驾驶汽车依靠人工智能、视觉计算、雷达、监控装置和全球定位***协同合作，让电脑可以在没有任何人类主动的操作下，自动安全地操作机动车辆。手动驾驶模式让驾驶员可以在1-4档内以手动方式自主选择合适的档位操纵车辆行驶，满足驾驶员的驾驶需求。路况信息是基于车载导航和高清地图获取的。用户在车辆上电后，在车载导航内输入目的地，车辆在高清地图上获取行驶路径，并根据行驶路径获得前方路段的路况信息。路况信息可以包括行驶道路的平整度、道路的坡度、道路转弯角度、前方是否有红绿灯以及前方道路是否堵塞。Specifically, the current driving mode of the vehicle includes an automatic driving mode and a manual driving mode. The automatic driving mode realizes an unmanned intelligent car through an on-board computer system. The automatic driving car relies on artificial intelligence, visual computing, radar, monitoring devices and global positioning systems to work together, so that the computer can automatically and safely operate the motor vehicle without any human active operation. The manual driving mode allows the driver to manually select the appropriate gear from 1 to 4 to operate the vehicle to meet the driver's driving needs. The road condition information is obtained based on the on-board navigation and high-definition map. After the vehicle is powered on, the user enters the destination in the on-board navigation, and the vehicle obtains the driving path on the high-definition map, and obtains the road condition information of the road ahead according to the driving path. The road condition information may include the flatness of the driving road, the slope of the road, the turning angle of the road, whether there is a traffic light ahead, and whether the road ahead is blocked.

S102、基于驾驶模式、路况信息以及用户的历史驾驶数据，获得车辆通过前方路段的车速范围，以及获得历史状态下车辆在路况信息对应路段下的故障信息。S102, based on the driving mode, road condition information and the user's historical driving data, obtain the speed range of the vehicle passing through the road section ahead, and obtain the fault information of the vehicle in the road section corresponding to the road condition information under the historical state.

具体地，用户的历史驾驶数据可以包括用户在通过当前路况信息所对应路段的车速，以及车辆在通过当前路况信息所对应路段时车辆发生的故障，以及当前路况信息是否为长上坡或长下坡的特殊路况，在该特殊路况下，车辆可能会发生故障。车速范围用于限制车辆在该路况信息对应的路段行驶的车速。车速范围可以用于确定车辆从起步到匀速驾驶的电机扭矩范围，根据扭矩范围可以计算电池充电和放电的功率。Specifically, the user's historical driving data may include the speed of the user when passing through the road section corresponding to the current road condition information, the vehicle failure when passing through the road section corresponding to the current road condition information, and whether the current road condition information is a special road condition of a long uphill or long downhill, under which the vehicle may fail. The speed range is used to limit the speed of the vehicle traveling on the road section corresponding to the road condition information. The speed range can be used to determine the motor torque range of the vehicle from starting to constant speed driving, and the battery charging and discharging power can be calculated based on the torque range.

另外，车辆行驶过程中，同时记录车辆在当前路况信息所对应路段的平均车速，按周期更新车辆内存储的车速范围，如每周更新一次或每月更新一次。In addition, during the driving process of the vehicle, the average speed of the vehicle on the road section corresponding to the current road condition information is recorded at the same time, and the speed range stored in the vehicle is updated periodically, such as once a week or once a month.

故障信息包括车辆在当前路况信息所对应路段下车辆报出的故障，例如，车辆在长上坡路况下，操作不当时电池可能会发生过温故障或过流故障；长下坡路况下操作不当时电池可能会发出过温或者回馈过流故障；在车辆电池满电的情况下，可能会出现禁止电流回充电池的故障，导致电流浪费。The fault information includes the faults reported by the vehicle on the road section corresponding to the current road condition information. For example, if the vehicle is operated improperly on a long uphill road, the battery may suffer from overtemperature or overcurrent faults; if the vehicle is operated improperly on a long downhill road, the battery may suffer from overtemperature or feedback overcurrent faults; when the vehicle battery is fully charged, a fault may occur that prohibits current from recharging the battery, resulting in current waste.

S103、根据车速范围，获得电机需求输出功率。S103: Obtain required output power of the motor according to the vehicle speed range.

具体地，电机需求输出功率是车速范围中的不同车速下，车辆行驶对应的所需输出的功率。在获取车速范围后，可以通过车速范围和电机需求输出功率，计算出车辆从起步到匀速驾驶的电机输出扭矩的范围，根据扭矩的范围可以计算得到电池放电和被充电的功率。Specifically, the motor required output power is the power required to be output when the vehicle is traveling at different speeds in the vehicle speed range. After obtaining the vehicle speed range, the motor output torque range from starting to constant speed driving can be calculated based on the vehicle speed range and the motor required output power. The battery discharge and charging power can be calculated based on the torque range.

S104、根据电机需求输出功率以及故障信息，确定车辆的电池输出功率。S104: Determine the battery output power of the vehicle according to the motor required output power and the fault information.

具体地，车辆的VCU(Vehicle Control Unit，整车控制器)可以根据电池的输出功率以及车辆的故障信息，在避免车辆发生故障的情况下，确定车辆电池实际的输出功率。Specifically, the vehicle's VCU (Vehicle Control Unit) can determine the actual output power of the vehicle battery based on the battery output power and the vehicle's fault information while avoiding vehicle failure.

结合分析历史故障与实时故障，可以进一步优化电池输出功率，以避免车辆的故障报出机制影响车辆的行驶。By combining the analysis of historical faults with real-time faults, the battery output power can be further optimized to avoid the vehicle's fault reporting mechanism affecting the vehicle's driving.

本公开实施例根据车辆当前的驾驶模式、前方路段的路况信息以及用户的历史驾驶数据，获得车辆通过前方路段的车速范围，从而根据车速范围确定出车辆的电机需求输出功率，并根据电机需求输出功率以及历史状态下车辆在所述路况信息对应路段下的故障信息，确定电池输出功率。相比于现有技术中根据用户的意愿控制车辆行驶，基于用户控制的电机转速控制电池输出能量，电池的瞬间输出功率会较大，通常能量回馈利用率较小。本公开考虑了车辆当前的驾驶模式、前方路段的路况信息以及用户的历史驾驶数据，确定出合理的电池输出功率，可以有效控制车辆行驶中的车速范围，保证车辆行驶速度不会波动过大，并可以根据合理的电池输出功率，优化电池的回馈功率，以便于动力电池回收能量，增加了车辆的续航里程。The disclosed embodiment obtains the speed range of the vehicle passing through the road section ahead according to the current driving mode of the vehicle, the road condition information of the road section ahead, and the user's historical driving data, thereby determining the required output power of the motor of the vehicle according to the speed range, and determining the battery output power according to the required output power of the motor and the fault information of the vehicle in the road section corresponding to the road condition information under the historical state. Compared with the prior art that controls the driving of the vehicle according to the user's wishes and controls the battery output energy based on the motor speed controlled by the user, the instantaneous output power of the battery will be larger, and the energy feedback utilization rate is usually smaller. The present disclosure takes into account the current driving mode of the vehicle, the road condition information of the road section ahead, and the user's historical driving data, and determines a reasonable battery output power, which can effectively control the speed range of the vehicle during driving, ensure that the vehicle's driving speed does not fluctuate too much, and can optimize the battery feedback power according to the reasonable battery output power, so as to facilitate the power battery to recover energy and increase the vehicle's cruising range.

进一步的，针对电池输出功率的优化，还可以在一定程度上增加电池的使用寿命，保证了电池的使用时长。Furthermore, the optimization of battery output power can also increase the battery life to a certain extent, ensuring the battery usage time.

另外，本公开在硬件设置和电路结构中并没有其他改动，而是基于控制逻辑的改变实现了上述目标，并没有其他成本的增加，车辆在成本相同的情况下满足用户对提升车辆续航里程的需求。In addition, the present invention does not have any other changes in the hardware settings and circuit structure, but achieves the above-mentioned goals based on changes in control logic without any increase in other costs. The vehicle meets the user's demand for improving the vehicle's cruising range at the same cost.

在一些实施例中，基于驾驶模式、路况信息以及用户的历史驾驶数据，获得车辆通过前方路段的车速范围的步骤，包括：In some embodiments, the step of obtaining a speed range of the vehicle passing through the road ahead based on the driving mode, road condition information, and historical driving data of the user includes:

在驾驶模式为自动驾驶模式的情况下，根据路况信息以及用户的历史驾驶数据，确定历史状态下车辆在路况信息对应的路段行驶的多个历史车速。When the driving mode is the automatic driving mode, multiple historical vehicle speeds of the vehicle traveling on the road section corresponding to the road condition information under the historical state are determined according to the road condition information and the user's historical driving data.

根据多个历史车速，确定车辆通过前方路段的车速范围。Based on multiple historical vehicle speeds, determine the speed range of the vehicle passing the road section ahead.

具体地，车辆在自动驾驶模式下，车辆可以通过自动驾驶***来操控车辆，不同路况信息由车辆本身来确定其行驶状态和车速范围。用户在历史驾驶过程中通过当前路况信息所对应路段的历史车速有多个，车速范围可以取一段时间内的多个历史车速得到车速范围，还可以取一段时间内的历史车速的平均值，并根据预设的误差作为车速范围。例如在一周时间内，车辆通过高速公路的上坡路段的车速分别为60km/h、62km/h、65km/h以及59km/h，则当前车辆通过高速公路的上坡路段的车速范围为59-65km/h，或者计算一周内车辆通过高速公路的上坡路段的车速平均值为61.5km/h，取误差为2.5km/h，在车速范围为59-64km/h。Specifically, when the vehicle is in the automatic driving mode, the vehicle can be controlled by the automatic driving system, and the vehicle itself determines its driving state and speed range based on different road condition information. During the historical driving process, the user has multiple historical vehicle speeds corresponding to the road section of the current road condition information. The speed range can be obtained by taking multiple historical vehicle speeds within a period of time, and the average value of the historical vehicle speed within a period of time can also be taken, and the speed range is based on the preset error. For example, within a week, the speeds of the vehicle passing through the uphill section of the highway are 60km/h, 62km/h, 65km/h and 59km/h respectively, then the current speed range of the vehicle passing through the uphill section of the highway is 59-65km/h, or the average speed of the vehicle passing through the uphill section of the highway within a week is calculated to be 61.5km/h, and the error is 2.5km/h, and the speed range is 59-64km/h.

在驾驶模式为手动驾驶模式的情况下，获取车辆的油门踏板信号、制动踏板信号以及车辆的整车运行模式。When the driving mode is the manual driving mode, the accelerator pedal signal, the brake pedal signal and the whole vehicle operation mode of the vehicle are obtained.

根据油门踏板信号、制动踏板信号以及用户的历史驾驶数据，确定用户的驾驶意图，驾驶意图包括紧急加速意图以及紧急制动意图。The user's driving intention is determined according to the accelerator pedal signal, the brake pedal signal and the user's historical driving data. The driving intention includes emergency acceleration intention and emergency braking intention.

根据路况信息、整车运行模式以及驾驶意图，确定车辆通过前方路段的车速范围。Determine the speed range of the vehicle through the road section ahead based on road condition information, vehicle operation mode and driving intention.

具体地，手动驾驶模式下车辆由用户操作，将用户的驾驶习惯融合在车辆控制***中。用户的历史驾驶数据可以是在车辆在历史行驶过程中，用户踩下车辆的油门踏板和/或车辆的制动踏板所产生的油门踏板信号和制动踏板信号，在用户控制车辆行驶时，根据油门踏板信号和制动踏板信号可以得到用户的驾驶意图。驾驶意图包括加速意图、减速意图、紧急加速意图和紧急制动意图，在用户的驾驶意图为加速意图和减速意图的情况下，可以让车辆在限制的车速范围内加速或减速，而在用户的驾驶意图为紧急加速意图和紧急制动意图的情况下，可以限制车辆的速度变化过快的情况，即限制车辆加速和减速时的加速度大小，避免浪费电池的输出能量。Specifically, in manual driving mode, the vehicle is operated by the user, and the user's driving habits are integrated into the vehicle control system. The user's historical driving data can be the accelerator pedal signal and brake pedal signal generated by the user stepping on the vehicle's accelerator pedal and/or the vehicle's brake pedal during the historical driving process of the vehicle. When the user controls the vehicle to drive, the user's driving intention can be obtained based on the accelerator pedal signal and the brake pedal signal. Driving intention includes acceleration intention, deceleration intention, emergency acceleration intention and emergency braking intention. When the user's driving intention is acceleration intention and deceleration intention, the vehicle can be accelerated or decelerated within the restricted speed range. When the user's driving intention is emergency acceleration intention and emergency braking intention, the vehicle's speed change can be limited to be too fast, that is, the acceleration size of the vehicle when accelerating and decelerating is limited to avoid wasting the battery's output energy.

整车运行模式一般包括经济模式(ECO模式)、运动模式(SPORT模式)以及针对冰雪天气的防滑模式，根据车辆前方的路况信息和整车运行模式以及用户的驾驶意图，可以确定车辆通过前方路段的车速范围。并根据车辆速度对应的电机扭矩，计算电池所使用的电流。根据电池电压来计算电池的输出功率。一般情况下，在整车运行模式为经济模式时，车辆保证电池的续航能力会更多限制电池的能量输出，因此经济模式下的车速范围对应的车速值会较小。车辆基于用户选择的运动模式，控制车辆电机的大扭矩输出，此时电池的放电功率大充电功率较小，因此运动模式下的车速范围对应的车速值较大。防滑模式是在车辆出现打滑或甩尾的情况下，通过车轮制动器作用或控制发动机扭矩，让车辆保持最佳的稳定性，此时可以不考虑电池的回馈功率，保证车辆的安全行驶。The vehicle operation mode generally includes economic mode (ECO mode), sports mode (SPORT mode) and anti-skid mode for ice and snow weather. According to the road condition information in front of the vehicle, the vehicle operation mode and the user's driving intention, the speed range of the vehicle passing through the road ahead can be determined. And the current used by the battery is calculated according to the motor torque corresponding to the vehicle speed. The output power of the battery is calculated according to the battery voltage. Generally, when the vehicle operation mode is economic mode, the vehicle will limit the energy output of the battery more to ensure the battery's endurance, so the speed range corresponding to the speed in economic mode will be smaller. Based on the sports mode selected by the user, the vehicle controls the high torque output of the vehicle motor. At this time, the battery has a large discharge power and a small charging power. Therefore, the speed range in sports mode corresponds to a large speed value. Anti-skid mode is to keep the vehicle in the best stability by applying wheel brakes or controlling engine torque when the vehicle slips or drifts. At this time, the feedback power of the battery can be ignored to ensure the safe driving of the vehicle.

在一些实施例中，根据电机需求输出功率以及故障信息，确定车辆的电池输出功率的步骤之前，方法还包括：In some embodiments, before the step of determining the battery output power of the vehicle according to the motor required output power and the fault information, the method further includes:

根据驾驶意图以及车速范围，从预设的多个电池功率map中获取目标电池功率map；According to the driving intention and the vehicle speed range, a target battery power map is obtained from a plurality of preset battery power maps;

根据电机需求输出功率以及故障信息，确定车辆的电池输出功率的步骤，包括：The steps of determining the battery output power of the vehicle according to the motor required output power and the fault information include:

根据电机需求输出功率、故障信息以及目标电池功率map，获得电池输出功率。The battery output power is obtained according to the motor required output power, fault information and target battery power map.

具体地，在车辆确定驾驶意图和车速范围后，可以根据预设的多个电池功率map选择对应的目标电池功率map，并可以得到电池输出功率。Specifically, after the vehicle determines the driving intention and the vehicle speed range, a corresponding target battery power map can be selected according to a plurality of preset battery power maps, and the battery output power can be obtained.

多个电池功率map可以包括2秒功率map、10秒功率map、30秒功率map、60秒功率map、120秒功率map以及持续功率map，分别表示车辆在下一时刻即下一个2秒、10秒、30秒、60秒、120秒以及持续的大电流的时候电池能够提供的最大的放电和被充电的功率，其中，持续功率map是车辆可以长时间使用的功率限值，例如可以1C放电一个小时。一般情况下将电池厂给出的10秒以下的功率限值作为电芯的峰值功率，将30秒以上的功率限制作为常值功率。功率限值主要是对高低温下的电池的充放电和能量反馈***进行约束。Multiple battery power maps may include a 2-second power map, a 10-second power map, a 30-second power map, a 60-second power map, a 120-second power map, and a continuous power map, which respectively represent the maximum discharge and charging power that the battery can provide at the next moment, i.e., the next 2 seconds, 10 seconds, 30 seconds, 60 seconds, 120 seconds, and a continuous high current. Among them, the continuous power map is the power limit that the vehicle can use for a long time, for example, it can discharge at 1C for one hour. In general, the power limit of less than 10 seconds given by the battery factory is used as the peak power of the battery cell, and the power limit of more than 30 seconds is used as the constant power. The power limit mainly constrains the charging and discharging of the battery and the energy feedback system at high and low temperatures.

另外，为了尽量减少峰值功率的使用，可以在满足时间的条件下限制用户的大功率输出，从而延长续驶里程。例如，根据加速踏板信号确定用户存在加速意图，然而为了避免急加速时电池产生的脉冲功率，可以不采用10秒一下的功率map，直接采用电池的30秒功率map，在支撑完30秒后，切换至60秒功率map，直至切换至持续功率map后不再变化。In addition, in order to minimize the use of peak power, the user's high power output can be limited under the condition of meeting the time, thereby extending the driving range. For example, the user's intention to accelerate can be determined based on the accelerator pedal signal. However, in order to avoid the pulse power generated by the battery during sudden acceleration, the power map of less than 10 seconds can be used instead of the 30-second power map of the battery. After supporting for 30 seconds, the power map is switched to the 60-second power map, and the map will not change until it switches to the continuous power map.

在一些实施例中，在获取车辆的油门踏板信号和制动踏板信号的步骤之后，方法还包括：In some embodiments, after the step of acquiring the accelerator pedal signal and the brake pedal signal of the vehicle, the method further includes:

根据油门踏板信号，获取车辆的油门踏板的第一变化率。According to the accelerator pedal signal, a first change rate of the accelerator pedal of the vehicle is acquired.

根据第一变化率，确定用户是否存在紧急加速意图。Based on the first change rate, it is determined whether the user has an emergency acceleration intention.

在确定用户存在紧急加速意图的情况下，控制车辆加速的加速度在第一预设范围内。When it is determined that the user has an emergency acceleration intention, the acceleration of the vehicle is controlled to be within a first preset range.

具体地，根据油门踏板信号可以采集到油门踏板信号在变化前的第一开度和变化后的第二开度，根据第一开度和第二开度之间的差值以及采集第一开度和第二开度的时间差值可以计算得到油门踏板的第一变化率，在第一变化率超过第一预设变化率的情况下，确定用户存在紧急加速意图，在第一变化率未超过第一预设变化率的情况下，确定用户存在加速意图。Specifically, based on the accelerator pedal signal, a first opening before the change and a second opening after the change of the accelerator pedal signal can be collected. Based on the difference between the first opening and the second opening and the time difference between collecting the first opening and the second opening, a first change rate of the accelerator pedal can be calculated. When the first change rate exceeds a first preset change rate, it is determined that the user has an emergency acceleration intention. When the first change rate does not exceed the first preset change rate, it is determined that the user has an acceleration intention.

确定用户存在加速意图时，第一变化率未超过第一预设变化率，即车速增加较为稳定，也就是正常驾驶状态。在确定用户存在紧急加速意图的情况下，第一变化率超过第一预设变化率，则控制车辆加速的加速度在第一预设范围内。控制车辆加速的加速度时，可以根据车辆第一开度对应的电机扭矩以及第二开度电机对应的电机扭矩，控制电机扭矩的变化率在预设的扭矩变化范围内。其中控制电机扭矩的变化率的方式可以是减小油门踏板第二开度对应的电机扭矩的值，或者可以是增加电机扭矩变化的时长。为了满足用户的加速需求一般采用增加电机扭矩变化的时长来满足用户的急加速意图，可以减少电池的输出能量，增加车辆续航里程。When it is determined that the user has an intention to accelerate, the first change rate does not exceed the first preset change rate, that is, the vehicle speed increase is relatively stable, that is, a normal driving state. When it is determined that the user has an intention to accelerate urgently, the first change rate exceeds the first preset change rate, then the acceleration of the vehicle is controlled to be within the first preset range. When controlling the acceleration of the vehicle, the rate of change of the motor torque can be controlled within a preset torque variation range according to the motor torque corresponding to the first opening of the vehicle and the motor torque corresponding to the second opening of the motor. The method of controlling the rate of change of the motor torque can be to reduce the value of the motor torque corresponding to the second opening of the accelerator pedal, or to increase the duration of the motor torque change. In order to meet the user's acceleration needs, it is generally adopted to increase the duration of the motor torque change to meet the user's emergency acceleration intention, which can reduce the output energy of the battery and increase the vehicle's cruising range.

根据制动踏板信号，获取车辆制动踏板的第二变化率。A second change rate of the vehicle brake pedal is acquired according to the brake pedal signal.

根据第二变化率，确定用户是否存在紧急制动意图。Based on the second change rate, it is determined whether the user has an emergency braking intention.

在确定用户存在紧急制动意图的情况下，控制车辆减速的加速度在第二预设范围内。When it is determined that the user has an emergency braking intention, the acceleration of the vehicle deceleration is controlled to be within a second preset range.

具体地，根据制动踏板信号可以采集到制动踏板信号在变化前的第三开度和变化后的第四开度，根据第三开度和第四开度之间的差值以及采集第三开度和第四开度的时间差值可以计算得到油门踏板的第二变化率，在第二变化率超过第二预设变化率的情况下，确定用户存在紧急制动意图，在第二变化率未超过第二预设变化率的情况下，确定用户存在减速意图。Specifically, based on the brake pedal signal, the third opening of the brake pedal signal before the change and the fourth opening after the change can be collected. Based on the difference between the third opening and the fourth opening and the time difference for collecting the third opening and the fourth opening, the second change rate of the accelerator pedal can be calculated. When the second change rate exceeds the second preset change rate, it is determined that the user has the intention of emergency braking. When the second change rate does not exceed the second preset change rate, it is determined that the user has the intention of deceleration.

确定用户存在减速意图时，第二变化率未超过第二预设变化率，即车速减速较为稳定。在确定用户存在紧急制动意图的情况下，第二变化率超过第二预设变化率，则控制车辆加速的加速度在第二预设范围内。控制车辆减速的加速度时，可以根据车辆第三开度对应的电机扭矩以及第四开度电机对应的电机扭矩，增加电机扭矩变化的时长以控制电机扭矩的变化率在预设的扭矩变化范围内。可以减少电池的输出能量，增加车辆续航里程。When it is determined that the user intends to decelerate, the second change rate does not exceed the second preset change rate, that is, the vehicle speed deceleration is relatively stable. When it is determined that the user intends to perform emergency braking, the second change rate exceeds the second preset change rate, and the acceleration of the vehicle is controlled to be within the second preset range. When controlling the acceleration of the vehicle deceleration, the duration of the motor torque change can be increased according to the motor torque corresponding to the third opening of the vehicle and the motor torque corresponding to the fourth opening motor to control the change rate of the motor torque within the preset torque change range. The output energy of the battery can be reduced to increase the vehicle's cruising range.

另外，目前根据高清地图可以判断车辆前方路段的红绿灯是红灯或绿灯。例如，在车辆前方路段的转弯后存在红绿灯，在车辆为自动驾驶模式下，若判断该红绿灯为红灯，则控制车辆降速的加速度，并将制动方式设置为电制动，可以使电池回收的能量最大化；若为绿灯，按照原本的车速行驶，在转弯时车辆无需减速或刹车，从而避免了电池的脉冲功率的使用，使电池的电流稳定输出，避免电池的能量浪费。In addition, based on the HD map, it is currently possible to determine whether the traffic light in front of the vehicle is red or green. For example, if there is a traffic light after the turn in the road ahead of the vehicle, when the vehicle is in the automatic driving mode, if the traffic light is determined to be red, the acceleration of the vehicle's deceleration is controlled, and the braking mode is set to electric braking, which can maximize the energy recovered by the battery; if the light is green, the vehicle drives at the original speed, and the vehicle does not need to slow down or brake when turning, thereby avoiding the use of battery pulse power, making the battery current output stable, and avoiding battery energy waste.

在一些实施例中，在根据车速范围，获得电池输出功率之后，方法还包括：In some embodiments, after obtaining the battery output power according to the vehicle speed range, the method further includes:

获取车辆的当前位置与目标位置之间的实际距离。Get the actual distance between the vehicle's current position and the target position.

根据电池输出功率以及实际距离，获得车辆从当前位置行驶至目标位置期间电池的最高温度。According to the battery output power and the actual distance, the maximum temperature of the battery during the vehicle's driving from the current position to the target position is obtained.

在最高温度未超过温度阈值的情况下，在车辆行驶过程中禁止开启水冷***。If the maximum temperature does not exceed the temperature threshold, it is prohibited to turn on the water cooling system while the vehicle is driving.

具体地，车辆当前位置和目标位置是基于用户输入车载导航的数据获得，目标位置为用户的目的地，而实际距离是车辆从当前位置行驶至目标位置的总路程，而不是直线距离。温度阈值是不损坏电池寿命的情况下电池的最高温度，车辆的水冷***用于对电池降温，水冷***开启时启动水泵和空调，耗费了电池的功率。在获得电池输出功率后，可以根据车辆行驶过程中电池的输出电流以及电池的放电倍率进行模拟仿真计算，推算出电池在理论上可以升高的最高温度的值，在该最高温度值没有超过电池所限制的温度阈值的情况下，可以不开启水冷***，节省电池的能量。例如，电池的水冷***开启条件为温度达到35摄氏度，而满足车辆预计路线及车速行驶的电池功率map所对应的温度阈值为45摄氏度，计算车辆从当前位置至目标位置电池的最高温度为40摄氏度，则可以禁止开启水冷，而不是在35摄氏度时就开启水冷。Specifically, the current position and target position of the vehicle are obtained based on the data input by the user into the vehicle navigation. The target position is the user's destination, and the actual distance is the total distance traveled by the vehicle from the current position to the target position, rather than the straight-line distance. The temperature threshold is the highest temperature of the battery without damaging the battery life. The water cooling system of the vehicle is used to cool the battery. When the water cooling system is turned on, the water pump and air conditioner are started, which consumes the power of the battery. After obtaining the battery output power, the value of the maximum temperature that the battery can theoretically rise can be deduced based on the output current of the battery and the discharge rate of the battery during the vehicle's driving process. If the maximum temperature value does not exceed the temperature threshold limited by the battery, the water cooling system can be turned off to save battery energy. For example, the condition for turning on the battery's water cooling system is that the temperature reaches 35 degrees Celsius, and the temperature threshold corresponding to the battery power map that meets the vehicle's expected route and speed is 45 degrees Celsius. If the maximum temperature of the battery from the current position to the target position is calculated to be 40 degrees Celsius, water cooling can be prohibited instead of turning on water cooling at 35 degrees Celsius.

在本实施例中，通过将车辆从当前位置行驶至目标位置期间电池的最高温度不超过温度阈值设置为在车辆行驶过程中禁止开启水冷的条件，可以在保证电池使用寿命的前提下，节省电池能量，进一步延长了车辆的续航里程。In this embodiment, by setting the maximum temperature of the battery not exceeding the temperature threshold during the vehicle's driving from the current position to the target position as a condition for prohibiting water cooling from being turned on during the vehicle's driving, battery energy can be saved while ensuring the battery's service life, thereby further extending the vehicle's cruising range.
