[0025] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.
[0026] It should be understood that when used in the present specification and the appended claims, the term "comprising" indicates the presence of described features, wholes, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components and / or combinations thereof.
[0027] In addition, in the description of the present application specification and the appended claims, the terms "first", "second", "third", etc. are only used to distinguish the descriptions and cannot be understood as indicating or implying relative importance.
[0028] At present, during the use of a vehicle, due to factors such as the vehicle's use environment and the owner's driving habits (for example, keeping the starter in working condition for a long time and frequently), the starter may be easily burned during the startup process, making the vehicle unable to drive normally.
[0029] In order to protect the starter, usually after the starter fails to start, a certain period of time is allowed to pass to allow the starter temperature to drop before starting the starter again, in order to optimize the owner's driving habits. However, this method is mainly affected by human factors and cannot effectively protect the starter to prevent the starter from burning during the starting process.
[0030] Based on this, in order to prevent the starter from ablation and reduce the failure rate of the starter, an embodiment of the present application provides a starter control method, wherein the starter control method can be applied to an on-board device of a vehicle.
[0031] Exemplarily, the above-mentioned vehicle-mounted equipment includes, but is not limited to, an electronic controller (Electronic Control Unit, ECU), a vehicle control unit (Vehicle Control Unit, VCU) and a transmission controller (Transmission Control Unit, TCU), which are not limited to this.
[0032] Specifically, the above-mentioned vehicle-mounted device can be specifically an ECU. Among them, ECU usually has fault self-diagnosis and protection functions. When a system in the vehicle fails, it can also automatically record the fault code in the internal memory (RAM) and adopt protection measures to read the alternative program from the above-mentioned inherent program to maintain the operation of the engine. Therefore, it can be considered that: in order to be able to perform fault self-diagnosis on the vehicle, ECU has the function of obtaining the parameters of each hardware device or software program in the vehicle when it is running. In this way, the vehicle can be self-diagnosed according to the acquired parameters.
[0033] See also Figure 1 , Figure 1 A flowchart of an engine control implementation provided by an embodiment of the present application is shown, and the method includes the following steps:
[0034] S101. Obtain the engine speed when the starter is started.
[0035] In one embodiment, the starter can convert the battery's electrical energy into mechanical energy, drive the starter flywheel to rotate, and drive the engine flywheel to run from low speed to high speed, thereby starting the vehicle. Therefore, when determining whether the starter is successfully started, it can be determined based on the engine speed. Based on this, the vehicle-mounted device can obtain the engine speed during the starter startup process.
[0036] The engine speed can be obtained by checking the engine speed meter on the vehicle dashboard. Usually, the number on the dashboard multiplied by 1000 is the engine speed. Alternatively, the engine speed can be obtained by using a crankshaft position sensor, which is not limited to this.
[0037] S102: If it is determined based on the rotation speed that the starter fails to start, obtain current vehicle parameters of the vehicle when the starter starts.
[0038] In one embodiment, determining whether the starter fails to start based on the rotation speed may be: if the rotation speed is less than a preset rotation speed, determining that the starter fails to start; if the rotation speed is greater than or equal to the preset rotation speed, determining that the starter succeeds to start.
[0039] The preset rotation speed can be set according to actual conditions and is not limited thereto.
[0040] It should be noted that the criterion for successful start of the starter is that the engine speed is greater than or equal to the preset speed. Therefore, if the starter fails to start normally due to its own fault, or the engine speed driven by the starter after normal start is not greater than or equal to the preset speed, the starter should be judged as a failure.
[0041] For example, when the ignition lock in the vehicle is turned to the start position, the relay and indicator light do not respond accordingly, and the starter does not work. In this case, the cause may be that the starter is faulty. For example, the ignition lock fuse is disconnected, the connector of the internal component circuit is in poor contact, or the starter relay is damaged, the battery is low, and other faults.
[0042] In another embodiment, when the starter can work normally but cannot drive the engine to rotate, or the engine speed cannot reach the expected speed, the cause may be improper engagement between the starter and the engine, burnt starter solenoid switch, over-tightening of the engine assembly or low engine temperature.
[0043] Based on this, it can be considered that there are multiple reasons for the starter failure. It should be noted that no matter what the reason is that the starter fails to start, the engine speed will eventually be less than the preset speed. And, when the starter can be successfully started, it can be considered that the engine speed will be greater than or equal to the preset speed.
[0044] In one embodiment, under normal circumstances, after the vehicle owner turns on the ignition, the starter electromagnetic switch is turned on, and the current of the battery drives the starter to operate. Therefore, when the starter is working, the working current is very large, and it will quickly heat up, which is easy to cause ablation. At the least, the relevant circuits inside the starter will be burned, and at the worst, a fire will be caused, endangering the safety of the vehicle and the owner.
[0045] Based on this, in order to avoid ablation, the on-board equipment can determine whether temperature overload will occur when the starter is started again according to the current vehicle parameters of the vehicle when the starter is started, so as to avoid ablation.
[0046] Among them, the current vehicle parameters include but are not limited to: starter operating temperature, ambient temperature, oil temperature, battery voltage, starter power, starter operating voltage, speed, start time, number of starts and start interval duration, etc., and there is no limitation on this.
[0047] It should be noted that in order to avoid ablation of the starter, most of the above current vehicle parameters are related to the starter. Among them, the ambient temperature and the rotation speed will affect the starter, or be affected by the starter. Therefore, the current vehicle parameters include not only the relevant parameters when the starter itself is started, but also the relevant parameters that affect the starter or are affected by the starter, which will not be described in detail.
[0048] As described above, the ECU has the function of obtaining the parameters of each hardware device or software program in the vehicle when it is running. Therefore, the vehicle-mounted device obtains the current vehicle parameters according to the ECU.
[0049] S103, predicting the temperature overload result when the starter is restarted according to the current vehicle parameters.
[0050] In one embodiment, predicting the temperature overload result according to the current vehicle parameters may be: inputting the current vehicle parameters into a pre-trained temperature model to obtain the temperature overload result.
[0051] The data for training the temperature model may be derived from the data accumulated from multiple starting tests on the vehicle or the starter. In order to make the prediction accuracy of the trained temperature model higher, the data for training the temperature model may be derived from the data accumulated from multiple starting tests on the vehicle, so that the acquired data is closer to the actual situation.
[0052] Specifically, the temperature model can predict the predicted temperature when the starter is started again based on the current vehicle parameters. Then, when the predicted temperature is greater than or equal to the preset temperature corresponding to the starter burn problem, the temperature overload result is determined to be temperature overload, and when the predicted temperature is lower than the corresponding preset temperature, the temperature overload result is determined to be temperature not overloaded.
[0053] S104. Control the starter according to the temperature overload result.
[0054] In one embodiment, when the temperature overload result is a temperature overload, it can be considered that the starter will be ablated if it is started again, so the starter is stopped. Therefore, in order to ensure vehicle safety, the vehicle-mounted device can control the vehicle to stop starting the starter.
[0055] In another embodiment, after controlling the vehicle to stop starting the starter, in order to determine the cause of the starter failure, the vehicle-mounted device can also determine abnormal start parameters with abnormalities from the current vehicle parameters according to the preset normal start parameters. Afterwards, the abnormal start parameters are matched with the preset failure causes, the target failure causes corresponding to the abnormal start parameters are determined, and the abnormal start parameters and the target failure causes are displayed.
[0056] Among them, each normal start parameter when the starter can start normally, or the parameter range of each normal start parameter can be pre-set in the vehicle-mounted device. At the same time, the failure reason corresponding to each abnormal start parameter can also be pre-set. Afterwards, the normal start parameter is compared with the corresponding current vehicle parameter. If any current vehicle parameter is inconsistent with the normal start parameter, or is not within the parameter range of the normal start parameter, the current vehicle parameter can be considered to be an abnormal start parameter. Then, the target failure reason is determined according to the abnormal start parameter.
[0057] For example, for the battery voltage, if the current battery voltage is lower than the preset voltage, the current battery voltage can be considered as an abnormal startup parameter. At this time, the corresponding target failure reason can be insufficient battery power.
[0058] The display of abnormal startup parameters and target failure reasons may include: displaying the abnormal startup parameters and target failure reasons on a display screen of an onboard device or an onboard terminal, so that the owner can handle the problem according to the target failure reasons. For example, when the target failure reason is insufficient power, the owner may be reminded to charge. In another embodiment, the onboard device may only display the failure reason.
[0059] In one embodiment, the temperature overload result may also be that the temperature is not overloaded. In this case, when the temperature overload result is that the temperature is not overloaded, it can be considered that the starter will not be burned if it is restarted. Therefore, the vehicle-mounted device can usually control the starter to restart.
[0060] However, the starter ablation phenomenon may be caused by frequent starting of the starter. Therefore, when determining that the temperature overload result is not overloaded, it is also necessary to obtain the total number of times the starter is started and the total duration, and then control the starter according to the total number and total duration.
[0061] Specifically, if the total number of times is less than or equal to the preset number of times, and the total duration is less than or equal to the first preset duration, the vehicle-mounted device can start the starter again; if the total number of times is greater than the preset number of times, and / or the total duration is greater than the first preset duration, the vehicle-mounted device stops starting the starter.
[0062] The preset number of times and the first preset duration can be set according to actual conditions. For example, the preset number of times can be 5 times, and the first preset duration can be 5 minutes.
[0063] In one embodiment, the total number of times is the number of times the starter is started, and the total duration is the interval between the start time when the starter is started for the first time and the current time. It should be noted that if the starter fails to be successfully started within the first preset time, or fails to be successfully started for multiple times in a row, it can be considered that the starter or the engine may have other undetected faults. Therefore, the starter can be stopped to avoid the loss of the circuit in the starter caused by multiple starts of the starter.
[0064] It should be added that when the starter needs to be started again, the starter should be started after a second preset time interval, so as to avoid frequent starting of the starter in a short period of time, which may increase the starter temperature and cause starter ablation.
[0065] Among them, the second preset duration can be set according to the actual situation, and there is no limitation on this. In another embodiment, the second preset duration can also be set according to the current actual situation. Specifically, the current vehicle parameters obtained by the vehicle-mounted device usually include the starter operating temperature. Based on this, the target interval duration corresponding to the current operating temperature can be determined according to the current operating temperature of the starter, and the correlation between the preset temperature and the preset interval duration. Afterwards, the vehicle-mounted device can determine the target interval duration as the above-mentioned second preset duration. Based on this, the vehicle-mounted device can flexibly adjust the interval duration when the starter is restarted according to the actual situation of the current operating temperature of the starter, thereby preventing starter ablation and reducing the starter failure rate.
[0066] It should be added that when the second preset time interval is required to start the starter, the successful start of the starter can be characterized as the engine speed being greater than the preset speed. Therefore, in order to make the starter start successfully as much as possible, the vehicle-mounted device can also preheat the engine within the second preset time interval to increase the engine oil temperature and water temperature to a suitable temperature, thereby improving the engine performance and extending the service life.
[0067] Reference Figure 2 , Figure 2 This is a flow chart for implementing a starter control method provided by another embodiment of the present application. When it is detected that the ignition lock in the vehicle is turned to the start position, it can be considered that the vehicle has a start demand. At this time, the starter is started, and the on-board device can obtain the engine speed when the starter is started, and when the speed is greater than or equal to the preset speed, it is determined that the starter is started successfully. At the same time, when the speed is less than the preset speed, it is determined that the starter fails to start. Then, the on-board device can obtain the current vehicle parameters of the vehicle when the starter is started, and input them into the temperature model to predict the temperature overload result when the starter is started next time. Finally, when it is determined that the temperature overload result is that the temperature is not overloaded, the starter is started again, that is, the above steps S101-S104 are repeated. If the temperature overload result is determined to be temperature overload, the starter is stopped directly, and the current vehicle parameters obtained are compared with the preset normal start parameters, the abnormal start parameters and the cause of the target failure are determined, and displayed.
