汽车快速启动方法、装置、设备及存储介质Automobile quick start method, device, device and storage medium

本申请要求在2021年3月26日提交中国专利局、申请号为202110327441.2的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。This application claims the priority of the Chinese Patent Application No. 202110327441.2 filed with the China Patent Office on March 26, 2021, the entire contents of which are incorporated herein by reference.

技术领域technical field

本申请实施例涉及汽车控制技术，例如涉及一种汽车快速启动方法、装置、设备及存储介质。The embodiments of the present application relate to automobile control technologies, for example, to a method, device, device, and storage medium for a quick start of an automobile.

背景技术Background technique

汽车发动机的相位指的是发动机的曲轴当前所处的角度。在汽车发动机启动过程中发动机的曲轴和凸轮轴信号的同步识别是发动机控制中决定发动机的启动性能的关键因素。The phasing of a car engine refers to the angle at which the engine's crankshaft is currently positioned. The synchronous recognition of the crankshaft and camshaft signals of the engine during the starting process of the automobile engine is a key factor in the engine control that determines the starting performance of the engine.

汽车电子控制器根据接收到的曲轴信号和凸轮轴信号确定发动机的相位，在同步识别后才能按照定义的缸序依次进行喷油和点火等正时控制。常见的做法为在发动机启动时通过对发动机上一次停机相位存储记忆值的读取，完成正时同步，进行预喷油。The automobile electronic controller determines the phase of the engine according to the received crankshaft signal and camshaft signal, and only after synchronous identification can the timing control such as fuel injection and ignition be performed sequentially according to the defined cylinder sequence. A common practice is to complete the timing synchronization and perform pre-injection by reading the memory value stored in the last stop phase of the engine when the engine is started.

针对上述方式之后需要根据曲轴信号与凸轮轴信号校验停机相位存储记忆值的准确性以此判断是否执行点火，若记忆相位判定错误，则造成尾气碳氢排放的上升以及燃油的浪费。而为了准确的识别发动机同步信息，就需要发动机在启动机的拖动下，形成一个完整周期360°的曲轴信号，造成启动时间的浪费。In view of the above method, it is necessary to verify the accuracy of the memory value stored in the stop phase according to the crankshaft signal and the camshaft signal to determine whether to execute ignition. In order to accurately identify the engine synchronization information, the engine needs to be driven by the starter to form a crankshaft signal with a complete cycle of 360°, resulting in a waste of start-up time.

下面结合附图和实施例对本申请作详细说明。可The present application will be described in detail below with reference to the accompanying drawings and embodiments. Can

实施例一Example 1

图1为本申请实施例一提供的汽车快速启动方法的流程图，本实施例可适用于V型双ECU(Electronic Control Unit，电子控制单元)控制的汽车的发动机的快速启动的情况，该方法可以由汽车快速启动装置来执行，包括如下步骤：Fig. 1 is the flow chart of the automobile quick start method provided by the first embodiment of the application, the present embodiment can be applied to the situation of the quick start of the engine of the automobile controlled by V-type dual ECU (Electronic Control Unit, electronic control unit), the method It can be carried out by the car's quick start device, including the following steps:

步骤110、获取汽车的发动机的当前停机相位，停机相位包括汽车的第一电子控制单元存储的第一停机相位和第二电子控制单元内存储的第二停机相位。Step 110: Acquire the current shutdown phase of the engine of the automobile, where the shutdown phase includes the first shutdown phase stored in the first electronic control unit of the automobile and the second shutdown phase stored in the second electronic control unit.

汽车在启动的过程中，发动机由静止状态过渡到工作状态，进而在变速箱的作用下将动力输送至汽车的车轮，从而实现汽车的启动。而要使发动机由静止状态过渡到工作状态，必须用外力转动发动机的曲轴，使气缸内吸入(或形成)可燃混合气并燃烧膨胀，工作循环才能自动进行。曲轴在外力作用下开始转动到发动机开始自动地怠速运转的全过程，称为发动机的启动。In the process of starting the car, the engine transitions from the static state to the working state, and then transmits the power to the wheels of the car under the action of the gearbox, thereby realizing the starting of the car. In order to make the engine transition from a static state to a working state, the crankshaft of the engine must be rotated by an external force, so that the combustible mixture is inhaled (or formed) in the cylinder and combusted and expanded, and the working cycle can be carried out automatically. The whole process from the crankshaft starting to rotate under the action of external force to the engine starting to idle automatically is called the starting of the engine.

在汽车发动机启动的过程中，首先需要完成发动机的信号同步，即发动机的曲轴和凸轮轴信号的同步识别。汽车电子控制器根据接收到的曲轴信号和凸轮轴信号确定发动机的相位，在同步识别后按照定义的缸序依次进行喷油和点火等正时控制。In the process of starting the car engine, it is first necessary to complete the signal synchronization of the engine, that is, the synchronization identification of the crankshaft and camshaft signals of the engine. The automotive electronic controller determines the phase of the engine according to the received crankshaft signal and camshaft signal, and performs timing control such as fuel injection and ignition in turn according to the defined cylinder sequence after synchronization identification.

而在部分V型发动机的汽车上通过设置有两个ECU(Electronic Control Unit，电子控制单元)分别控制左右两侧的发动机缸的喷油和点火等的正时控制。在工作过程中两个电子控制单元分别对应设置有完整的检测传感器，所述检测传感器设置为检测发动机的工作状态，其中每个电子控制单元对应设置的检测传感器包括至少一套曲轴位置传感器和凸轮轴位置传感器(一套曲轴位置传感器和凸轮轴位置传感器由一个曲轴位置传感器和一个凸轮轴位置传感器组成)，曲轴位置传感器和凸轮轴位置传感器分别对曲轴和凸轮轴的运动进行监控，并且由两个电子控制单元协同工作，以保证对发动机的可靠的正时控制。In some V-engine vehicles, two ECUs (Electronic Control Unit, electronic control unit) are provided to control the timing control of fuel injection and ignition of the engine cylinders on the left and right sides respectively. During the working process, the two electronic control units are respectively provided with complete detection sensors, and the detection sensors are set to detect the working state of the engine. The detection sensors corresponding to each electronic control unit include at least one set of crankshaft position sensors and cams. Shaft position sensor (a set of crankshaft position sensor and camshaft position sensor consists of a crankshaft position sensor and a camshaft position sensor), the crankshaft position sensor and the camshaft position sensor monitor the movement of the crankshaft and the camshaft respectively, and are composed of two The two electronic control units work together to ensure reliable timing control of the engine.

在具体实现过程中，对于该类具备双电子控制单元进行控制的发动机，在前一次工作结束时将两个电子控制单元检测到的曲轴信号和凸轮轴信号进行处理获得发动机在停机时的停机相位，即通过发动机内设置的曲轴位置传感器获取曲轴的曲轴信息(转动信息、位置信息)，进而判断曲轴所处的位置，获得曲轴在停止状态下的停机相位，即本申请实施例中所述的当前停机相位。而对于两个电子控制单元，其内分别存储有对应的曲轴位置传感器检测到的曲轴信号确定的发动机停机相位(当前停机相位)。In the specific implementation process, for this type of engine controlled by dual electronic control units, the crankshaft signal and camshaft signal detected by the two electronic control units are processed at the end of the previous work to obtain the stop phase of the engine when the engine is stopped. , that is, the crankshaft information (rotation information, position information) of the crankshaft is obtained through the crankshaft position sensor provided in the engine, and then the position of the crankshaft is judged, and the stop phase of the crankshaft in the stopped state is obtained, that is, the embodiment described in the present application. The current shutdown phase. For the two electronic control units, the engine stop phase (current stop phase) determined by the crankshaft signal detected by the corresponding crankshaft position sensor is stored therein respectively.

在本申请实施例中，在汽车的电子控制单元上线时，预先读取前次发动机停机时两个电子控制单元中存储的当前停机相位，即本申请实施例中所述的第一电子控制单元存储的第一停机相位和第二电子控制单元内存储的第二停机相位。汽车的电子控制单元上线可以是多种情况，例如：在汽车***钥匙后启动；又或者是汽车在***钥匙旋动钥匙启动汽车时读取；又或者是在按动汽车上的一键启动按钮后触发读取第一电子控制单元存储的第一停机相位和第二电子控制单元内存储的第二停机相位；又或者是其他的启动条件触发对第一电子控制单元存储的第一停机相位和第二电子控制单元内存储的第二停机相位的读取，在此不做限定。In the embodiment of the present application, when the electronic control unit of the automobile is online, the current shutdown phase stored in the two electronic control units when the engine was stopped last time is read in advance, that is, the first electronic control unit described in the embodiment of the present application. A first shutdown phase stored and a second shutdown phase stored in the second electronic control unit. The electronic control unit of the car can be online in various situations, for example: the car starts after inserting the key; or the car reads when the key is inserted and the key is turned to start the car; or the one-button start button on the car is pressed Then trigger to read the first shutdown phase stored in the first electronic control unit and the second shutdown phase stored in the second electronic control unit; or other start conditions trigger the first shutdown phase and The reading of the second stop phase stored in the second electronic control unit is not limited here.

步骤120、判断第一停机相位和第二停机相位的差值是否在预设的阈值范围内；Step 120, judging whether the difference between the first shutdown phase and the second shutdown phase is within a preset threshold range;

若差值在预设的阈值范围内，则执行步骤130；If the difference is within the preset threshold range, perform step 130;

若差值在预设的阈值范围外，则执行步骤140。If the difference is outside the preset threshold range, step 140 is executed.

汽车的发动机的停机相位是以角度值(停机相位值，大小在0°-720°范围内)的形式进行存储，并且由于两个电子控制单元的停机相位为分别根据与其对应的曲轴位置传感器的曲轴信号确定的，因此在两个电子控制单元中存储的停机相位的值会存在一定的偏差，而当两个停机相位的值的偏差在一定范围内时对于汽车的发动机启动并不存在影响，并且在汽车的发动机启动之后还可以根据发动机上设置的曲轴位置传感器和凸轮轴位置传感器进行二次的同步校对，因此，在汽车的发动机的启动阶段允许两个电子控制单元内存储的停机相位的值存在一定范围的偏差。The stop phase of the engine of the car is stored in the form of an angle value (the stop phase value, the size is in the range of 0°-720°), and because the stop phases of the two electronic control units are respectively based on the corresponding crankshaft position sensors. The crankshaft signal is determined, so the value of the stop phase stored in the two electronic control units will have a certain deviation, and when the deviation of the value of the two stop phases is within a certain range, it will not affect the engine start of the car. And after the engine of the car is started, a secondary synchronous calibration can be performed according to the crankshaft position sensor and the camshaft position sensor set on the engine. Therefore, during the start-up phase of the car's engine, the two electronic control units are allowed to store the stop phase. There is a range of deviations in the value.

在本申请实施例中，通过简单的将两个电子控制单元内存储的停机相位的值进行相减，获得两个电子控制单元内存储的停机相位的差值，然后再将该差值与预设的阈值范围进行对比，即可快速的确定两个电子控制单元内存储的停机相位是否符合启动条件，也就是说确定两个电子控制单元内存储的停机相位是否可以有效，是否可以直接用于汽车的发动机的新一次启动的同步识别。In the embodiment of the present application, the difference between the shutdown phases stored in the two electronic control units is obtained by simply subtracting the values of the shutdown phases stored in the two electronic control units, and then the difference is added to the preset value. By comparing the set threshold ranges, you can quickly determine whether the shutdown phases stored in the two electronic control units meet the starting conditions, that is to say, determine whether the shutdown phases stored in the two electronic control units are valid and can be directly used for Synchronous recognition of a new start of the car's engine.

步骤130、以第一停机相位或第二停机相位作为发动机的目标相位完成目标曲轴信号的同步。Step 130 , using the first stop phase or the second stop phase as the target phase of the engine to complete the synchronization of the target crankshaft signal.

在具体实现中，当两个电子控制单元内存储的停机相位的差值在预设的阈值范围内时，表征此时两个电子控制单元内存储的停机相位可直接用于汽车的发动机的启动，从而快速的完成发动机的曲轴信号和凸轮轴信号的同步工作，跳过在启动时所需的同步识别工作，从而使发动机可直接进入到启动状态下，避免错误的喷油和点火所带来的时间和能源的浪费。In a specific implementation, when the difference between the stop phases stored in the two electronic control units is within a preset threshold range, it indicates that the stop phases stored in the two electronic control units at this time can be directly used for starting the engine of the car , so as to quickly complete the synchronization of the crankshaft signal and the camshaft signal of the engine, skip the synchronous identification work required at startup, so that the engine can directly enter the startup state, avoiding the wrong fuel injection and ignition. waste of time and energy.

步骤140、通过识别发动机的参考曲轴信号完成目标曲轴信号的同步。Step 140, complete the synchronization of the target crankshaft signal by identifying the reference crankshaft signal of the engine.

在具体实现中，当两个电子控制单元内存储的停机相位的差值在预设的阈值范围之外时，即代表两个电子控制单元内存储的停机相位并不符合汽车的发动机的启动条件，此时需要重新对汽车的发动机的曲轴信号和凸轮轴信号进行同步识别，以保证电子控制单元在合适的时间控制发动机的喷油和点火。In a specific implementation, when the difference between the stop phases stored in the two electronic control units is outside the preset threshold range, it means that the stop phases stored in the two electronic control units do not meet the starting conditions of the engine of the car , at this time, it is necessary to re-identify the crankshaft signal and the camshaft signal of the engine of the car to ensure that the electronic control unit controls the fuel injection and ignition of the engine at the appropriate time.

在本实施例中，获取汽车的发动机的两个电子控制单元内存储的当前停机相位，并对两个电子控制单元内存储的当前停机相位进行判断是否符合预设的条件，判断是否将两个电子控制单元内存储的当前停机相位直接用于汽车的发动机的启动，可实现发动机的快速启动，降低汽车的发动机启动同步识别所需要耗费的时间，以及避免在同步识别过程中错误喷油时所带来的资源浪费以及尾气碳氢排放的上升，保证发动机的燃油经济性和排放量控制。In this embodiment, the current shutdown phases stored in the two electronic control units of the engine of the automobile are obtained, and it is judged whether the current shutdown phases stored in the two electronic control units meet the preset conditions, and whether the two The current stop phase stored in the electronic control unit is directly used for the start of the engine of the car, which can realize the rapid start of the engine, reduce the time required for the synchronous identification of the engine of the automobile, and avoid the time spent in the synchronous identification process when the wrong fuel is injected. The resulting waste of resources and the increase in exhaust hydrocarbon emissions ensure the fuel economy and emission control of the engine.

实施例二Embodiment 2

图2为本申请实施例二提供的一种汽车快速启动方法的流程图。本实施例是在实施例一的基础上进行的细化，详细描述了当前停机相位的获取等相关特征的方法。参考图2，该方法包括：FIG. 2 is a flowchart of a method for quickly starting a vehicle according to Embodiment 2 of the present application. This embodiment is a refinement on the basis of Embodiment 1, and describes in detail the method for acquiring the current shutdown phase and other related features. Referring to Figure 2, the method includes:

步骤201、基于汽车的发动机的停机信号和初始曲轴信号获取当前停机相位，初始曲轴信号为发动机停止运动前检测到的曲轴信号。Step 201 , obtaining the current stop phase based on the stop signal of the engine of the vehicle and the initial crankshaft signal, where the initial crankshaft signal is the crankshaft signal detected before the engine stops moving.

在本申请实施例中，在发动机的前次使用停机时，响应汽车的发动机的停机信号获取曲轴位置传感器检测到的曲轴信号(初始曲轴信号)，然后根据曲轴信号确定发动机停机时曲轴的停止位置，获取对应的停机相位作为当前停机相位。In the embodiment of the present application, when the engine is stopped for the previous use, the crankshaft signal (initial crankshaft signal) detected by the crankshaft position sensor is obtained in response to the stop signal of the engine of the automobile, and then the stop position of the crankshaft when the engine is stopped is determined according to the crankshaft signal. , and obtain the corresponding shutdown phase as the current shutdown phase.

其中，曲轴位置传感器的作用就是确定曲轴的位置，也就是曲轴的转角以及发动机转速。它通常要配合凸轮轴位置传感器一起来工作——确定基本点火时刻。通过曲轴位置传感器和凸轮轴位置传感器的信号来计算获得曲轴运动位置，通过曲轴位置传感器，可以知道哪缸活塞处于上止点，通过凸轮轴位置传感器，可以知道哪缸活塞是在压缩冲程中。Among them, the function of the crankshaft position sensor is to determine the position of the crankshaft, that is, the angle of rotation of the crankshaft and the speed of the engine. It usually works with the camshaft position sensor - to determine the basic ignition timing. The crankshaft position is calculated by the signals of the crankshaft position sensor and the camshaft position sensor. Through the crankshaft position sensor, it can be known which cylinder piston is at the top dead center, and through the camshaft position sensor, which cylinder piston is in the compression stroke.

此外，在发动机中，对应凸轮轴还设置有凸轮轴位置传感器，凸轮轴位置传感器是一种传感装置，也叫同步信号传感器，它是一个气缸判别定位装置，向电子控制单元输入凸轮轴位置信号，是点火控制的主控信号。凸轮轴位置传感器设置为采集凸轮轴动角度信号，并输入电子控制单元，以便确定点火时刻和喷油时刻，凸轮轴位置传感器又称为气缸识别传感器。凸轮轴位置传感器的功用是采集配气凸轮轴的位置信号，并输入电子控制单元，以便电子控制单元识别气缸压缩上止点，从而进行顺序喷油控制、点火时刻控制和爆燃控制。此外，凸轮轴位置信号还用于发动机启动时识别出第一次点火时刻。因为凸轮轴位置传感器能够识别哪一个气缸活塞即将到达上止点，所以称为气缸识别传感器。In addition, in the engine, the corresponding camshaft is also provided with a camshaft position sensor. The camshaft position sensor is a sensing device, also called a synchronization signal sensor, which is a cylinder discriminating and positioning device that inputs the camshaft position to the electronic control unit. Signal is the main control signal of ignition control. The camshaft position sensor is set to collect the camshaft moving angle signal and input it to the electronic control unit to determine the ignition time and fuel injection time. The camshaft position sensor is also called the cylinder identification sensor. The function of the camshaft position sensor is to collect the position signal of the valve camshaft and input it to the electronic control unit, so that the electronic control unit can identify the top dead center of cylinder compression, so as to perform sequential fuel injection control, ignition timing control and detonation control. In addition, the camshaft position signal is used to identify the moment of the first ignition when the engine is started. Because the camshaft position sensor can identify which cylinder piston is about to reach top dead center, it is called a cylinder identification sensor.

在具体实现中，可通过曲轴位置传感器获知汽车的发动机在停止时的曲轴信号，从而根据曲轴信号判断发动机的曲轴的停机位置，获得对应的停机相位。即本申请实施例中所述的当前停机相位。In a specific implementation, the crankshaft signal when the engine of the vehicle is stopped can be obtained through the crankshaft position sensor, so as to determine the stop position of the crankshaft of the engine according to the crankshaft signal, and obtain the corresponding stop phase. That is, the current shutdown phase described in the embodiments of the present application.

示例性的，步骤201可以包括：Exemplarily, step 201 may include:

步骤2011、基于汽车的发动机的停机信号和初始曲轴信号，确定发动机的正转结束位置的正转相位值和反转结束位置的反转相位值。Step 2011: Determine the forward rotation phase value at the forward rotation end position and the reverse rotation phase value at the reverse rotation end position of the engine based on the stop signal of the engine of the vehicle and the initial crankshaft signal.

在汽车的发动机停机时，由于飞轮的惯性作用，发动机并不会立刻停止转动，并且在发动机内部的阻力作用下围绕正转结束位置做钟摆运动，直至最终停止。而在汽车的发动机的曲轴位置传感器中，其检测原理为检测经过曲轴位置传感器的齿的数量判断曲轴的转角和发动机速度，采集结果为呈现一定规律的波形图，通过计算在单个周期内曲轴信号的波动的上升沿或下降沿数量确定经过曲轴位置传感器位置的齿的数量，进而确定曲轴所处的位置。而在检测过程中由于检测结果为波形图，并不能够直接检测到曲轴是处于正转状态还是反转状态。因此需要在曲轴信号的波形图中确定发生反转的位置，进而确定发动机的正转结束位置和反转结束位置。When the engine of the car is stopped, due to the inertia of the flywheel, the engine will not stop rotating immediately, and under the action of the internal resistance of the engine, it will make a pendulum movement around the end of the forward rotation until it finally stops. In the crankshaft position sensor of the engine of the car, the detection principle is to detect the number of teeth passing through the crankshaft position sensor to determine the rotation angle of the crankshaft and the engine speed. The number of rising or falling edges of the fluctuation determines the number of teeth that pass the position of the crankshaft position sensor, which in turn determines the position of the crankshaft. In the detection process, since the detection result is a waveform diagram, it cannot be directly detected whether the crankshaft is in a forward rotation state or a reverse rotation state. Therefore, it is necessary to determine the position where the reverse rotation occurs in the waveform diagram of the crankshaft signal, and then determine the forward rotation end position and the reverse rotation end position of the engine.

在一个可选的实施例中，步骤2011可以包括：In an optional embodiment, step 2011 may include:

步骤20111、基于汽车的发动机的停机信号发出时间，确定初始曲轴信号中低电平由第一宽度变为第二宽度的位置作为发动机的正转结束位置，其中第一宽度不等于第二宽度。Step 20111: Determine the position where the low level in the initial crankshaft signal changes from the first width to the second width as the forward rotation end position of the engine, where the first width is not equal to the second width.

步骤20112、获取正转结束位置对应的初始曲轴信号，确定发动机的曲轴相位值作为正转相位值。Step 20112: Obtain the initial crankshaft signal corresponding to the forward rotation end position, and determine the crankshaft phase value of the engine as the forward rotation phase value.

步骤20113、确定正转相位值后初始曲轴信号中低电平由第二宽度变为第一宽度的位置作为发动机的反转结束位置。Step 20113: After determining the forward rotation phase value, the position where the low level in the initial crankshaft signal changes from the second width to the first width is used as the reverse rotation end position of the engine.

步骤20114、获取反转结束位置对应的初始曲轴信号，确定发动机的曲轴相位值作为反转相位值。Step 20114: Obtain the initial crankshaft signal corresponding to the reverse rotation end position, and determine the crankshaft phase value of the engine as the reverse rotation phase value.

步骤2012、利用正转相位值减去反转相位值获得发动机的当前停机相位。Step 2012 , using the forward rotation phase value to subtract the reverse rotation phase value to obtain the current stop phase of the engine.

对于汽车的发动机的曲轴的正转结束位置和反转结束位置的确定，由于发动机的曲轴在运动过程中的速度由正转减速至0，然后再反向加速然后再减速至0，接着曲轴再正转返回，以此重复摆动，最终停止。For the determination of the forward rotation end position and reverse rotation end position of the crankshaft of the automobile engine, since the speed of the crankshaft of the engine during the movement is decelerated from forward rotation to 0, and then accelerated in the reverse direction and then decelerated to 0, then the crankshaft re- Forward and return, repeat the swing, and finally stop.

并且在本申请实施例中采用三个霍尔传感器组成的曲轴位置传感器对曲轴位置信息进行获取，该曲轴位置传感器输出的曲轴信号在曲轴正转时低电平的跨度被处理为第一宽度，在曲轴反转时低电平的跨度被处理为第二宽度，而高电平的跨度则与曲轴转动的速度成反比关系，即曲轴的转速越大高电平的跨度越小，曲轴的转速越小高电平的跨度越大。And in the embodiment of the present application, a crankshaft position sensor composed of three Hall sensors is used to acquire the crankshaft position information, and the low-level span of the crankshaft signal output by the crankshaft position sensor is processed as the first width when the crankshaft rotates forwardly, When the crankshaft is reversed, the low-level span is processed as the second width, and the high-level span is inversely proportional to the speed of crankshaft rotation, that is, the greater the crankshaft rotational speed, the smaller the high-level span, and the higher the crankshaft rotational speed. The smaller the span of the high level is.

在具体实现中，当汽车的发动机收到停机信号后停机，曲轴在惯性的作用下继续正转，此时获取的初始曲轴信号中的低电平为与正转对应的第一宽度，当其速度为0时并反生反转时，其处于正转结束位置，其即将发生反转，此时所获取到的初始曲轴信号的低电平的跨度将由正转的第一宽度变为反转的第二宽度。同理，当曲轴反转至反转结束位置时，其速度将变为0，随后发生正转，低电平的跨度将由第二宽度变为第一宽度。In the specific implementation, when the engine of the car stops after receiving the stop signal, the crankshaft continues to rotate forward under the action of inertia, and the low level in the initial crankshaft signal obtained at this time is the first width corresponding to the forward rotation. When the speed is 0 and the reverse is reversed, it is at the end of the forward rotation, and it is about to reverse. At this time, the span of the low level of the obtained initial crankshaft signal will change from the first width of the forward rotation to the reverse rotation. the second width. Similarly, when the crankshaft is reversed to the end position of the reverse rotation, its speed will become 0, and then forward rotation will occur, and the span of the low level will change from the second width to the first width.

在一个示例中，曲轴位置传感器输出的曲轴正转时的低电平的跨度为50us，曲轴反转时的低电平的跨度为100us。在汽车的发动机收到停机信号后停机时，获取到的初始曲轴信号的低电平的跨度为50us，正转结束后发生反转时低电平的跨度将由50us变为100us。In one example, the span of the low level output by the crankshaft position sensor when the crankshaft is rotating forward is 50us, and the span of the low level when the crankshaft is rotating reversely is 100us. When the engine of the car stops after receiving the stop signal, the low level span of the obtained initial crankshaft signal is 50us, and the low level span will change from 50us to 100us when reverse rotation occurs after the forward rotation.

由此可判断正转结束位置和反转结束位置，最终确定发动机的停机位置，进而确定发动机的停机相位。Thereby, the end position of forward rotation and the end position of reverse rotation can be judged, and finally the stop position of the engine can be determined, and then the stop phase of the engine can be determined.

在本申请实施例中，在前述步骤中基于发动机的曲轴信号确定了发动机的曲轴的正转结束位置和反转结束位置，以及对应的正转相位值和反转相位值，因此可以通过正转相位值减去反转相位值的方式获取得到曲轴最终的停机位置的相位值。In the embodiment of the present application, the forward rotation end position and the reverse rotation end position of the crankshaft of the engine are determined based on the crankshaft signal of the engine in the preceding steps, as well as the corresponding forward rotation phase value and reverse rotation phase value. The phase value of the final stop position of the crankshaft is obtained by subtracting the reverse phase value from the phase value.

示例性的，由于发动机的曲轴在停机时极容易发生钟摆运动，沿某一位置往复运动多次，并最终停止，由此可统计多次发生转动方向改变的位置以及对应的正转相位值和反转相位值，将多次的正转相位值和反转相位值分别累加，然后再以累加之后的正转相位值减去累加之后的反转相位值获得最终的停机位置的停机相位。Exemplarily, since the crankshaft of the engine is prone to pendulum motion when it is stopped, it reciprocates along a certain position for many times, and finally stops, so that the positions where the rotation direction changes many times and the corresponding positive rotation phase values and values can be counted. Reverse the phase value, accumulate the forward phase value and reverse phase value for multiple times, and then subtract the accumulated reverse phase value from the accumulated forward rotation phase value to obtain the final stop phase of the stop position.

步骤202、将当前停机相位写入汽车的电子控制单元进行掉电保存。Step 202 , write the current shutdown phase into the electronic control unit of the vehicle for power-down storage.

在前述步骤中汽车的两个电子控制单元分别基于曲轴位置传感器和凸轮轴位置传感器采集的数据确定对应的发动机在前次使用中停机的位置的当前停机相位。在获取对应的当前停机相位后，可通过掉电保存的方式将其存储到汽车的两个电子控制单元的存储空间内进行保存，以在下一次汽车启动上电时能够被读取用于新一次的汽车的发动机启动。In the preceding steps, the two electronic control units of the automobile determine the current stop phase of the position where the corresponding engine was stopped in the previous use based on the data collected by the crankshaft position sensor and the camshaft position sensor, respectively. After the corresponding current shutdown phase is obtained, it can be stored in the storage space of the two electronic control units of the car by means of power-off saving, so that it can be read for a new time when the car is powered on next time. car's engine starts.

步骤203、获取汽车的发动机的当前停机相位，停机相位包括汽车的第一电子控制单元存储的第一停机相位和第二电子控制单元内存储的第二停机相位。Step 203: Obtain the current shutdown phase of the engine of the automobile, where the shutdown phase includes the first shutdown phase stored in the first electronic control unit of the automobile and the second shutdown phase stored in the second electronic control unit.

在实际实现中，在汽车的发动机再次被启动时，电子控制单元上电读取前次发动机停机时两个电子控制单元中存储的当前停机相位，即本申请实施例中所述的第一电子控制单元存储的第一停机相位和第二电子控制单元内存储的第二停机相位。读取和触发过程可参考实施例一中步骤110中的相应记载，在此不再赘述。In actual implementation, when the engine of the car is started again, the electronic control unit is powered on to read the current shutdown phase stored in the two electronic control units when the engine was stopped last time, that is, the first electronic control unit described in the embodiments of the present application. A first shutdown phase stored in the control unit and a second shutdown phase stored in the second electronic control unit. For the process of reading and triggering, reference may be made to the corresponding records in step 110 in the first embodiment, which will not be repeated here.

步骤204、判断第一停机相位和第二停机相位的差值是否在预设的阈值范围内；Step 204, judging whether the difference between the first shutdown phase and the second shutdown phase is within a preset threshold range;

若差值在预设的阈值范围内，则执行步骤205；If the difference is within the preset threshold range, go to step 205;

若差值在预设的阈值范围外，则执行步骤206。If the difference is outside the preset threshold range, step 206 is executed.

步骤205、以第一停机相位或第二停机相位作为发动机的目标相位完成目标曲轴信号的同步。Step 205 , using the first stop phase or the second stop phase as the target phase of the engine to complete the synchronization of the target crankshaft signal.

步骤206、通过识别发动机的参考曲轴信号完成目标曲轴信号的同步。Step 206 , complete the synchronization of the target crankshaft signal by identifying the reference crankshaft signal of the engine.

在本申请实施例中，通过简单的将两个电子控制单元内存储的停机相位的值进行相减，获得两个电子控制单元内存储的停机相位的差值，然后再降该差值与预设的阈值范围进行对比，即可快速的确定两个电子控制单元内存储的停机相位是否符合启动条件，也就是说确定两个电子控制单元内存储的停机相位是否可以有效，是否可以直接用于汽车的发动机的新一次启动的同步识别。In the embodiment of the present application, the difference between the shutdown phases stored in the two electronic control units is obtained by simply subtracting the values of the shutdown phases stored in the two electronic control units, and then the difference is reduced to the preset value. By comparing the set threshold ranges, you can quickly determine whether the shutdown phases stored in the two electronic control units meet the starting conditions, that is to say, determine whether the shutdown phases stored in the two electronic control units are valid and can be directly used for Synchronous recognition of a new start of the car's engine.

当两个电子控制单元内存储的停机相位的差值在预设的阈值范围内时，表征此时两个电子控制单元内存储的停机相位可直接用于汽车的发动机的启动，从而快速的完成发动机的曲轴信号和凸轮轴信号的同步工作，跳过在启动时所需的同步识别工作，从而使发动机可直接进入到启动状态下，避免错误的喷油和点火所带来的时间和能源的浪费。When the difference between the stop phases stored in the two electronic control units is within the preset threshold range, it indicates that the stop phases stored in the two electronic control units can be directly used to start the engine of the car, so as to quickly complete the The synchronous work of the crankshaft signal and the camshaft signal of the engine skips the synchronous identification work required at the time of starting, so that the engine can directly enter the starting state, avoiding the time and energy consumption caused by wrong fuel injection and ignition. waste.

当两个电子控制单元内存储的停机相位的差值在预设的阈值范围之外时，即代表两个电子控制单元内存储的停机相位并不符合汽车的发动机的启动条件，此时需要重新对汽车的发动机的曲轴信号和凸轮轴信号进行同步识别，以保证电子控制单元在合适的时间控制发动机的喷油和点火。实现过程可参考实施例一中步骤120、步骤130和步骤140中的描述，在此不再过多赘述。When the difference between the stop phases stored in the two electronic control units is outside the preset threshold range, it means that the stop phases stored in the two electronic control units do not meet the starting conditions of the car's engine. Simultaneously identify the crankshaft signal and camshaft signal of the car's engine to ensure that the electronic control unit controls the fuel injection and ignition of the engine at the appropriate time. For the implementation process, reference may be made to the descriptions in step 120, step 130, and step 140 in Embodiment 1, which will not be repeated here.

在一个可选的实施例中，步骤206可以包括：In an optional embodiment, step 206 may include:

步骤2061、获取发动机的参考曲轴信号，参考曲轴信号为发动机启动时获取到的曲轴信号。Step 2061: Obtain a reference crankshaft signal of the engine, where the reference crankshaft signal is a crankshaft signal obtained when the engine is started.

在具体实现中，曲轴信号可通过发动机上设置的曲轴位置传感器获取，在启动发动机时获取曲轴位置传感器的信号作为所需的参考曲轴信号。In a specific implementation, the crankshaft signal can be obtained through a crankshaft position sensor provided on the engine, and the signal of the crankshaft position sensor is obtained as the required reference crankshaft signal when the engine is started.

步骤2062、确定参考曲轴信号中的缺齿特征。Step 2062: Determine the missing tooth feature in the reference crankshaft signal.

在曲轴位置判断过程中，曲轴位置传感器是通过检测曲轴信号轮上的齿隙变化来产生信号的，并在曲轴上设置“缺齿”来表示曲轴对应缸活塞达到上止点时的位置。In the crankshaft position judgment process, the crankshaft position sensor generates a signal by detecting the change of the backlash on the crankshaft signal wheel, and sets “missing teeth” on the crankshaft to indicate the position of the crankshaft corresponding cylinder piston when it reaches the top dead center.

步骤2063、基于缺齿特征完成目标曲轴信号的同步。Step 2063, completing the synchronization of the target crankshaft signal based on the missing tooth feature.

开始启动时，曲轴和凸轮轴开始转动，电子控制单元(ECU，Electronic Control Unit)开始检测曲轴位置传感器通过检测曲轴信号轮上的齿隙变化来产生的曲轴信号，由于没有参考齿，电子控制单元无法计数，即不能确定检测到的齿是几号齿，也无法获知当前曲轴的角度。因此需要通过在曲轴上设置“缺齿”来表示曲轴对应缸活塞达到上止点时的位置，以此标定曲轴的参考位置。在本申请实施例中，在第一停机相位和第二停机相位的差值超出预设的阈值范围时通过获取参考曲轴信号中的缺齿特征确定曲轴位置，从而实现同步。When starting, the crankshaft and camshaft start to rotate, and the electronic control unit (ECU, Electronic Control Unit) starts to detect the crankshaft signal generated by the crankshaft position sensor by detecting the change of the backlash on the crankshaft signal wheel. Since there is no reference tooth, the electronic control unit It cannot be counted, that is, it cannot be determined what tooth number is detected, nor can the current crankshaft angle be known. Therefore, it is necessary to set the "missing tooth" on the crankshaft to indicate the position of the crankshaft when the cylinder and piston reach the top dead center, so as to calibrate the reference position of the crankshaft. In the embodiment of the present application, when the difference between the first stop phase and the second stop phase exceeds a preset threshold range, the crankshaft position is determined by acquiring the missing tooth feature in the reference crankshaft signal, thereby realizing synchronization.

在一个实施例中，步骤2063可以包括：In one embodiment, step 2063 may include:

步骤20631、获取发动机的凸轮轴信号；Step 20631, obtain the camshaft signal of the engine;

步骤20632、基于凸轮轴信号和缺齿特征完成目标曲轴信号的同步。Step 20632: Complete the synchronization of the target crankshaft signal based on the camshaft signal and the missing tooth feature.

通过检测曲轴信号轮上的齿隙变化来产生信号的，并通过“缺齿”来表示曲轴对应缸活塞达到上止点时的位置。由于发动机一个工作循环曲轴要转两圈，所以仅靠曲轴位置传感器就无法判断曲轴当下究竟处在哪个冲程，而在同一工作循环内，凸轮轴却只转一圈，这样曲轴所处的冲程就可由凸轮轴位置来确定了。而实现这一配合的前提是，曲轴位置传感器信号与凸轮轴位置传感器信号之间必须保持同步。示例性的，检测到缺齿信号时，电子控制单元开始计数，如果数完58个齿后再次检测到缺齿信号，那么该缺齿信号被确认，曲轴自同步成功。此时可以获得曲轴0°-360°间的角度，因为发动机一个喷油循环即喷完四个缸，凸轮轴转动一圈，曲轴转动两圈。The signal is generated by detecting the change of the backlash on the crankshaft signal wheel, and the "missing tooth" is used to indicate the position of the crankshaft when the corresponding cylinder piston reaches the top dead center. Since the crankshaft rotates twice in one working cycle of the engine, the crankshaft position sensor alone cannot determine which stroke the crankshaft is currently in. In the same working cycle, the camshaft only rotates once, so that the stroke of the crankshaft is Can be determined by the camshaft position. The prerequisite for this coordination is that the crankshaft position sensor signal and the camshaft position sensor signal must be synchronized. Exemplarily, when the missing tooth signal is detected, the electronic control unit starts counting. If the missing tooth signal is detected again after counting 58 teeth, the missing tooth signal is confirmed and the crankshaft self-synchronizes successfully. At this time, the angle between 0° and 360° of the crankshaft can be obtained, because the engine sprays four cylinders in one fuel injection cycle, the camshaft rotates once, and the crankshaft rotates twice.

在上述实施例的基础上，还可以结合第一停机相位和第二停机相位的判断发动机的曲轴所处的冲程。例如，通过判断第一停机相位和第二停机相位是否处于相同的冲程内，以及所处的冲程判断曲轴所处的冲程。On the basis of the above embodiment, the stroke of the crankshaft of the engine can also be determined in combination with the first stop phase and the second stop phase. For example, the stroke of the crankshaft is determined by judging whether the first stop phase and the second stop phase are in the same stroke, and the stroke they are in.
