实施例一

图1为本发明实施例一提供了一种车辆起动机控制方法的流程图，本实施例可适用于保护车辆起动机的情况，该方法可以由车辆起动机控制装置来执行，该车辆起动机控制装置可以采用硬件和/或软件的形式实现，该车辆起动机控制装置可配置于计算机中。如图1所示，该方法包括：

S110、获取当前车辆的属性信息和起动间隔，根据属性信息和起动间隔生成起动信号。

其中，起动机可以将储存在蓄电池内的电能变成机械能，具体是由直流电动机产生动力，经传动机构带动发动机曲轴转动，从而实现发动机的起动。起动系统包括以下部件：蓄电池、点火开关(起动开关)、起动机总成、起动继电器等。控制器在进行起动机控制时会先获取当前车辆的属性信息和起动间隔，属性信息包括整车状态信息和发动机转速信息。整车状态信息包括档位信息、制动踏板位置信息以及点火开关位置信息，发动机转速是指发动机曲轴每分钟的回转数。起动间隔是指本次起动距离上次起动之间的时间间隔。当属性信息和起动间隔满足起动条件时即可生成起动信号，起动信号是控制起动机开始运行的信号。

在一个具体的实现中，本方法可以应用于起动机运转保护控制系统，包括起动保护控制器，保护控制器包括速度采集模块、控制输出模块和电压采集模块等，整个电路还包括蓄电池、点火开关、曲轴速度传感器、起动保护控制模块、保险丝、起动继电器、电压采集点、缓啮合继电器、电磁开关吸引线圈、电磁开关保持线圈、电机和保险丝等零部件。

具体的，司机按下钥匙门，点火开关闭合，控制模块进行判断，满足起动条件后，接通继电器，电磁开关吸引线圈和保持线圈同时作用，电磁力拉动起动机内部拨叉使驱动齿与发动机齿圈啮合，起动机进行换啮合过程，当啮合一定深度后，电磁开关触点接通，把吸引线圈短接，电动机直接与蓄电池相连，提供较大的转矩，带动发动机转动。本实施例的技术方案是在现有起动系统的基础上，增加了电压采集信号，考虑和驱动齿轮与发动机齿轮啮合不顺畅的情况，当电压大于某一固定值时，则判断啮合成功，否则判断顶齿，从而避免发生电磁开关烧损的情况。

S120、根据起动信号控制车辆起动机起动，并获取起动相关信息，其中，起动相关信息包括单次起动时长、发动机转速和继电器电压。

具体的，根据起动信号可以控制车辆起动机起动并获取起动相关信息，起动相关信息包括单次起动时长、发动机转速和继电器电压，继电器电压包括电磁开关吸合前电压和电磁开关吸合后电压。

S130、当起动相关信息满足复位条件时生成复位信号，根据复位信号控制起动机断开。

其中，复位条件包括单次起动时长大于第一预设阈值，第一指定时间内发动机转速低于第一转速阈值或者高于第二转速阈值以及电压差值小于等于预设差值阈值。

图2为本发明实施例一提供了一种车辆起动机控制方法的流程图，步骤S130主要包括如下的步骤S131至步骤S138：

S131、判断单次起动时长是否大于第一预设阈值，若是，执行S132，否则，执行S133。

S132、直接生成复位信号，根据复位信号控制起动机断开。

具体的，当单次起动时长超过第一预设阈值时，控制器会直接生成复位信号，进而控制起动机断开。第一预设阈值是控制器根据环境温度传感器采集的温度，使软件在10-30S内自行调整，示例性的，第一预设阈值可以是30s，即起动机单次起动时长超过20s时，停止工作。

S133、判断第一指定时间内发动机转速是否低于第一转速阈值或者高于第二转速阈值，若是，执行S134，否则，执行S135-S136。

具体的，第一指定时间是控制器根据环境温度传感器采集的温度，使软件在1-5s内自行调整。第一转速阈值和第二转速阈值是用户根据发动机性能进行设置的，其中，第二转速阈值高于第一转速阈值。第二转速阈值是指怠速转速，需要说明的是，第二转速阈值设定应在高于发动机最低起动转速情况下，尽可能的低，避免发动机返拖起动机。示例性的，第一指定时间可以是5s，第一转速阈值可以是50r/min，第二转速阈值可以是400r/min。当发动机转速接近怠速转速400r/min时，停止工作。当起动机工作5s内，且发动机转速低于50r/min时，停止工作。

S134、生成复位信号，根据复位信号控制起动机断开。

S135、确定第二指定时间内电磁开关吸合后电压和电磁开关吸合前电压的电压差值。

具体的，起动机包括电磁开关、缓啮合继电器、电磁开关、电机、拨叉、换向器以及驱动齿头等部分，在缓啮合继电器前端可以读取到电磁开关吸合前电压,继电器导通后，电磁开关的吸合线圈和保持线圈会有一个200A左右的电流，由于蓄电池内阻的存在，导致此时缓啮合继电器前端会产生变化的电磁开关吸合后电压，当发生驱动齿与飞轮齿圈顶齿时，电磁开关线圈一直得电，电压差值，当驱动齿与飞轮齿圈正常啮合时，起动机电机工作，电压差值一般在500ms内会增大1.6V以上，故通过在起动继电器前端监测电压，可以实现对电磁开关的保护。

S136、判断电压差值是否小于等于预设差值阈值，若是，执行S137，否则，执行S138。

S137、生成复位信号，根据复位信号控制起动机断开。

具体的，预设差值阈值可以根据历史数据中起动机与发动机大量配合的基础上进行确定，预设差值阈值可以为1.6V，当电压差值在500ms内未增大1.6V时，断开起动信号，起动机停止工作，避免电磁开关烧损。

具体实施方式：本实施方式可以根据整车状态和发动机转速信息判断是否满足起动机的起动条件，所述起动条件包括挡位在空挡、制动踏板在制动位、发动机转速为零，钥匙在ST位，当满足上述条件发送起动信号，当发送起动信号后，两次起动小于固定间隔时间，或在固定时间内，转速低于第一固定速度限值或发动机转速大于第二固定速度值，或单次起动时长大于固定值，或采集的电压U2在500ms内，上升小于1.6V，当以上条件任一一个满足时，发送复位信号，控制器会控制起动继电器断开。

S138、生成起动机正常运行信号，将正常运行信号发送至用户终端进行展示。

具体的，当起动机正常运行时，控制器也会生成起动机正常运行信号发送至用户终端进行展示。确保用户及时了解起动机的工作状态。

本发明实施例的技术方案，通过获取当前车辆的属性信息和起动间隔，然后根据属性信息和起动间隔生成起动信号控制车辆起动机起动，然后通过获取单次起动时长、发动机转速和继电器电压判断是否满足复位条件，当满足复位条件时生成复位信控制起动机断开，系统可靠性高，有效解决电磁开关烧损及电机烧损问题，提高了起动机的使用寿命。

S230、当属性信息满足起动条件时，生成起动信号，其中，属性信息包括整车状态信息和发动机转速信息。

具体的，预设时间间隔可以是15s，即连续两次起动间隔大于15S，才允许起动机工作，并且当属性信息满足起动条件时才会生成起动信号控制起动机工作，即档位在在空挡位，制动踏板在制动位，发动机转速等于0并且点火开关在ST位时，才允许起动机工作。需要说明的是，起动条件需要都满足，起动机才会开始工作，而复位条件只需满足任意一个，控制器就会断开起动信号使起动机停止工作，避免电磁开关烧损。

本发明实施例通过利用发动机转速信号、制动踏板位置信息、档位信息、点火开关信息、起动时长信息、二次起动间隔时长信息、起动信号、环境温度信息、起动机控制电压信息等资源进行综合判断，进而起动机的起动与关闭。

Further, the terms "including" and "having" and any variation thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or equipment comprising a series of steps or units need not be limited to those steps or units expressly listed, but may include other steps or units not clearly listed or inherent to those processes, methods, products or equipment.

Example 1

FIG 1 provides a flowchart of a vehicle starter control method provided in Example 1 of the present invention, the present embodiment may be applied to the case of protecting the vehicle starter, the method may be performed by the vehicle starter control device, the vehicle starter control device may be implemented in the form of hardware and / or software, the vehicle starter control device may be configured in a computer. As shown in Figure 1, the method comprises:

S110, obtain the attribute information and starting interval of the current vehicle, and generate a starting signal according to the attribute information and starting interval.

Among them, the starter can turn the electrical energy stored in the battery into mechanical energy, specifically generated by the DC motor, and drive the engine crankshaft to rotate through the transmission mechanism, so as to realize the starting of the engine. The starting system includes the following components: battery, ignition switch (starting switch), starter assembly, starting relay, etc. When the controller controls the starter, it will first obtain the attribute information and starting interval of the current vehicle, including the vehicle status information and engine speed information. The vehicle status information includes gear information, brake pedal position information and ignition switch position information, and engine speed refers to the number of revolutions per minute of the engine crankshaft. The starting interval refers to the time interval between this start and the last start. When the attribute information and starting interval meet the starting conditions, the starting signal can be generated, and the starting signal is the signal that controls the start of the starter operation.

In a specific implementation, the present method can be applied to the starter operation protection control system, including the starting protection controller, the protection controller includes a speed acquisition module, a control output module and a voltage acquisition module, etc., the whole circuit also includes a battery, ignition switch, crankshaft speed sensor, starting protection control module, fuse, starting relay, voltage collection point, slow meshing relay, electromagnetic switch suction coil, electromagnetic switch holding coil, motor and fuse and other parts.

Specifically, the driver presses the key door, ignition opens and closes, the control module makes a judgment, after meeting the starting conditions, the relay is turned on, the electromagnetic switch attracts the coil and holds the coil at the same time, the electromagnetic force pulls the starter internal fork to make the drive tooth meshing with the engine ring gear, the starter carries out the meshing process, when the meshing is at a certain depth, the electromagnetic switch contact is turned on, the suction coil is short-connected, the motor is directly connected to the battery, providing greater torque and driving the engine to rotate. The technical solution of the present embodiment is to increase the voltage acquisition signal on the basis of the existing starting system, consider and drive the gear and the engine gear meshing is not smooth, when the voltage is greater than a fixed value, the meshing is judged to be successful, otherwise judge the top tooth, thereby avoiding the occurrence of electromagnetic switch burning.

S120, control the starting of the vehicle starter according to the starting signal, and obtain the relevant information of the start, including the duration of a single start, engine speed and relay voltage.

Specifically, according to the starting signal, the vehicle starter can be controlled and the start-related information can be obtained, and the start-related information includes the single starting time, engine speed and relay voltage, and the relay voltage includes the voltage before the electromagnetic switch is closed and the voltage after the electromagnetic switch is closed.

S130, when the starting information meets the reset conditions, the reset signal is generated, and the starter is controlled to open according to the reset signal.

Among them, the reset conditions include a single start time greater than the first preset threshold, the engine speed below the first speed threshold or above the second speed threshold within the first specified time, and the voltage difference less than or equal to the preset difference threshold.

FIG 2 provides a flowchart of a vehicle starter control method provided in Example 1 of the present invention, step S130 mainly includes the following steps S131 to steps S138:

S131, determine whether the single start time is greater than the first preset threshold, if so, execute S132, otherwise, execute S133.

S132, directly generate a reset signal, and control the starter to disconnect according to the reset signal.

Specifically, when a single start time exceeds the first preset threshold, the controller directly generates a reset signal to control the starter to disconnect. The first preset threshold is the controller according to the temperature collected by the ambient temperature sensor, so that the software adjusts itself within 10-30S, for example, the first preset threshold can be 30s, that is, when the starter starts for more than 20s, it stops working.

S133, determine whether the engine speed is lower than the first speed threshold or higher than the second speed threshold within the first specified time, if so, execute S134, otherwise, execute S135-S136.

Specifically, the first specified time is the temperature collected by the controller according to the ambient temperature sensor, so that the software adjusts itself within 1-5s. The first speed threshold and the second speed threshold are set by the user according to the engine performance, where the second speed threshold is higher than the first speed threshold. The second speed threshold refers to the idle speed, it should be noted that the second speed threshold setting should be as low as possible when it is higher than the minimum starting speed of the engine to avoid the engine from dragging the starter. For example, the first specified time can be 5s, the first speed threshold can be 50r/min, and the second speed threshold can be 400r/min. When the engine speed is close to the idle speed of 400r/min, it stops working. When the starter works within 5s and the engine speed is lower than 50r/min, it stops working.

S134, generate a reset signal, and control the starter to disconnect according to the reset signal.

S135, determine the voltage difference between the voltage after the solenoid switch is closed and the voltage before the electromagnetic switch is closed in the second specified time.

Specifically, the starter includes electromagnetic switch, slow meshing relay, electromagnetic switch, motor, fork, commutator and drive tooth head and other parts, in the front end of the slow meshing relay can read the voltage before the electromagnetic switch is closed, after the relay is turned on, the electromagnetic switch suction coil and holding coil will have a current of about 200A, due to the existence of the internal resistance of the battery, resulting in the slow meshing relay front end will produce a change in the voltage after the electromagnetic switch is closed, when the drive tooth and flywheel ring gear top tooth occurs, The solenoid switch coil has been electrified, the voltage difference, when the driving tooth and the flywheel ring gear normal meshing, the starter motor work, the voltage difference will generally increase by more than 1.6V within 500ms, so by monitoring the voltage at the front end of the starting relay, the protection of the electromagnetic switch can be realized.

S136, determine whether the voltage difference is less than or equal to the preset difference threshold, if so, execute S137, otherwise, execute S138.

S137, generate a reset signal, and control the starter to open according to the reset signal.

Specifically, the preset difference threshold can be determined on the basis of a large number of cooperation between the starter and the engine in the historical data, the preset difference threshold can be 1.6V, when the voltage difference does not increase by 1.6V within 500ms, disconnect the starting signal, the starter stops working, and the electromagnetic switch burns out.

As shown in Figure 1, the method comprises:

S110, obtain the attribute information and starting interval of the current vehicle, and generate a starting signal according to the attribute information and starting interval.

Among them, the starter can turn the electrical energy stored in the battery into mechanical energy, specifically generated by the DC motor, and drive the engine crankshaft to rotate through the transmission mechanism, so as to realize the starting of the engine. The starting system includes the following components: battery, ignition switch (starting switch), starter assembly, starting relay, etc. When the controller controls the starter, it will first obtain the attribute information and starting interval of the current vehicle, including the vehicle status information and engine speed information. The vehicle status information includes gear information, brake pedal position information and ignition switch position information, and engine speed refers to the number of revolutions per minute of the engine crankshaft. The starting interval refers to the time interval between this start and the last start. When the attribute information and starting interval meet the starting conditions, the starting signal can be generated, and the starting signal is the signal that controls the start of the starter operation.

In a specific implementation, the present method can be applied to the starter operation protection control system, including the starting protection controller, the protection controller includes a speed acquisition module, a control output module and a voltage acquisition module, etc., the whole circuit also includes a battery, ignition switch, crankshaft speed sensor, starting protection control module, fuse, starting relay, voltage collection point, slow meshing relay, electromagnetic switch suction coil, electromagnetic switch holding coil, motor and fuse and other parts.

Specifically, the driver presses the key door, ignition opens and closes, the control module makes a judgment, after meeting the starting conditions, the relay is turned on, the electromagnetic switch attracts the coil and holds the coil at the same time, the electromagnetic force pulls the starter internal fork to make the drive tooth meshing with the engine ring gear, the starter carries out the meshing process, when the meshing is at a certain depth, the electromagnetic switch contact is turned on, the suction coil is short-connected, the motor is directly connected to the battery, providing greater torque and driving the engine to rotate. The technical solution of the present embodiment is to increase the voltage acquisition signal on the basis of the existing starting system, consider and drive the gear and the engine gear meshing is not smooth, when the voltage is greater than a fixed value, the meshing is judged to be successful, otherwise judge the top tooth, thereby avoiding the occurrence of electromagnetic switch burning.

S120, control the starting of the vehicle starter according to the starting signal, and obtain the relevant information of the start, including the duration of a single start, engine speed and relay voltage.

S131, determine whether the single start time is greater than the first preset threshold, if so, execute S132, otherwise, execute S133.

S132, directly generate a reset signal, and control the starter to disconnect according to the reset signal.

Specifically, when a single start time exceeds the first preset threshold, the controller directly generates a reset signal to control the starter to disconnect. The first preset threshold is the controller according to the temperature collected by the ambient temperature sensor, so that the software adjusts itself within 10-30S, for example, the first preset threshold can be 30s, that is, when the starter starts for more than 20s, it stops working.

S133, determine whether the engine speed is lower than the first speed threshold or higher than the second speed threshold within the first specified time, if so, execute S134, otherwise, execute S135-S136.

Specifically, the first specified time is the temperature collected by the controller according to the ambient temperature sensor, so that the software adjusts itself within 1-5s. The first speed threshold and the second speed threshold are set by the user according to the engine performance, where the second speed threshold is higher than the first speed threshold. The second speed threshold refers to the idle speed, it should be noted that the second speed threshold setting should be as low as possible when it is higher than the minimum starting speed of the engine to avoid the engine from dragging the starter. For example, the first specified time can be 5s, the first speed threshold can be 50r/min, and the second speed threshold can be 400r/min. When the engine speed is close to the idle speed of 400r/min, it stops working. When the starter works within 5s and the engine speed is lower than 50r/min, it stops working.

S136, determine whether the voltage difference is less than or equal to the preset difference threshold, if so, execute S137, otherwise, execute S138.

S137, generate a reset signal, and control the starter to open according to the reset signal.

Specifically, the preset difference threshold can be determined on the basis of a large number of cooperation between the starter and the engine in the historical data, the preset difference threshold can be 1.6V, when the voltage difference does not increase by 1.6V within 500ms, disconnect the starting signal, the starter stops working, and the electromagnetic switch burns out.

S138, generate the normal operation signal of the starter, and send the normal operation signal to the user terminal for display.

Specifically, when the starter is running normally, the controller will also generate a starter normal operation signal and send it to the user terminal for display. Ensure that the user is aware of the working status of the starter in a timely manner.
