The following describes in detail the control method, device, terminal, medium and other technical schemes of the hybrid electric vehicle provided by the application with reference to specific embodiments.
Fig. 1 shows a step flowchart of a control method of a hybrid vehicle in an embodiment of the present application, and as shown in fig. 1, the control method of a hybrid vehicle may mainly include the following steps S100 to S400.
And S100, comparing the oil tank liquid level information with a preset threshold value.
And step 200, if the oil tank liquid level information is lower than the preset threshold value and the engine cannot be started normally, generating fault information for temporary storage, and sending a low oil prompt.
And step S300, monitoring the next starting condition of the engine when the oil tank liquid level information rises.
And step S400, processing the fault information according to the starting condition of the engine.
According to the control method of the hybrid electric vehicle, the oil tank liquid level information is compared with the preset threshold, if the oil tank liquid level information is lower than the preset threshold and the engine cannot be started normally, namely the fact that the oil quantity of the vehicle is lower at the moment is indicated, the engine is failed to start due to the fact that the oil quantity is insufficient, and the engine is not failed, so that fault information generated by the failure of starting the engine is temporarily stored, and a low oil quantity prompt is sent to a user to remind the user of refueling the vehicle; when the vehicle is refueled, the oil tank liquid level information rises, the influence of insufficient oil quantity is eliminated, whether the engine has a fault or not is determined according to the starting condition of the next engine, and whether the fault information temporarily stored before is required to be reported or not is determined.
Therefore, according to the control method for the hybrid electric vehicle, when the engine fails to start, fault information is temporarily stored, after the vehicle is refueled, whether the fault information is reported is determined according to the starting condition of the engine, and therefore the condition that the system fault is wrongly reported when the oil quantity of the vehicle is insufficient is improved in a mode of adjusting the fault information reporting strategy.
The following describes in detail each method step in the control method of the hybrid vehicle.
And S100, comparing the oil tank liquid level information with a preset threshold value.
Specifically, a liquid level sensor arranged on the oil tank module detects an oil tank to obtain oil tank liquid level information, then the oil tank module sends the oil tank liquid level information to the whole vehicle control system, and the whole vehicle control system compares the oil tank liquid level information with a preset threshold, wherein the preset threshold is a standard for measuring whether the residual oil amount of the oil tank is too small.
In other possible embodiments, the vehicle control system may compare the tank level information with a preset threshold value only when the engine cannot be started normally, so as to determine whether there is a possibility that the engine cannot be started normally due to too little oil.
It can be appreciated that the action of comparing the oil tank level information with the preset threshold value by the vehicle control system is not affected by the monitoring of the starting condition of the engine, so that the action of comparing the oil tank level information with the preset threshold value can occur before, after or simultaneously when the engine cannot be started normally, and is not particularly limited herein.
And step 200, if the oil tank liquid level information is lower than the preset threshold value and the engine cannot be started normally, generating fault information for temporary storage, and sending a low oil prompt.
Specifically, after the vehicle control system compares the oil tank liquid level information with the preset threshold, determining that the oil tank liquid level information is lower than the preset threshold, indicating that the residual oil amount of the oil tank is smaller at the moment, if the engine cannot be started normally at the moment, judging that the reason for the incapability of starting normally is probably due to the fact that the residual oil amount of the oil tank is smaller, temporarily storing fault information generated due to the incapability of starting normally in a memory instead of directly displaying the fault information, so that misleading users are avoided, and outputting a low oil amount prompt to remind the users to refuel the vehicle in time.
And step S300, monitoring the next starting condition of the engine when the oil tank liquid level information rises.
Specifically, when the vehicle control system judges that the liquid level of the oil tank rises according to the liquid level information of the oil tank fed back by the oil tank module, the fact that the user refuels the vehicle at the moment is indicated, the influence of too little oil quantity on the starting of the engine is eliminated, and the starting condition of the engine at the next time is monitored.
And step S400, processing the fault information according to the starting condition of the engine.
Specifically, after the user refuels the vehicle, the influence of the too small oil quantity on the engine start is eliminated, whether the engine has a fault is judged according to whether the engine can be started normally or not when the engine is started next time, and then a corresponding processing mode is adopted for the fault information stored in the memory.
Further, as shown in fig. 2, in a possible embodiment, the processing of the fault information according to the start condition of the engine in the step S400 includes the following step S401 and step S402.
Step S401, if the engine is started normally, determining that the running condition of the engine is no system fault.
Specifically, after the liquid level of the oil tank rises, if the engine can be started normally at the next start, it is indicated that the failure of the engine to start normally before is caused by too little oil in the oil tank, and the engine itself has no fault, so that the running condition of the engine is determined as no system fault.
And step S402, when the running condition of the engine is that no system fault exists, clearing the temporarily stored fault information.
Specifically, if the vehicle control system determines that the running condition of the engine is no system fault, it indicates that the fault information stored in the memory previously belongs to false alarm, so that the fault information is cleared.
Further, as shown in fig. 3, in a possible embodiment, the processing of the fault information according to the start condition of the engine in the step S400 includes the following steps S403 and S404.
Step S403, if the engine cannot be started normally, determining that the running condition of the engine is that there is a system fault.
Specifically, after the liquid level of the oil tank rises, if the engine still cannot be started normally at the next start, the engine still cannot be started normally even if the influence on the engine caused by the too small oil amount of the oil tank is eliminated, namely, the engine has a fault, so that the running condition of the engine is determined to have a system fault.
And step S404, when the running condition of the engine is that the system fault exists, displaying the fault information based on a dashboard.
Specifically, when the vehicle control system determines that the running condition of the engine is that a system fault exists, fault information stored in the memory is displayed through the instrument panel so as to remind a user of timely maintaining the vehicle.
It can be appreciated that in another possible embodiment, when the vehicle control system determines that the running condition of the engine is that there is a system fault, besides displaying the fault information through the dashboard, the help seeking information can be automatically sent to the destination terminal provided in the maintenance center according to the fault information, so that the maintenance center can acquire the fault condition of the current vehicle as soon as possible, and help is provided for a user using the current vehicle.
So, above-mentioned embodiment provides after the oil tank liquid level information risees, confirms according to whether the engine can normally start to clear away or show the trouble information of keeping in to the blind display trouble information produces misleading condition emergence to the user when the engine can't normally start among the prior art, has improved the practicality of this application technical scheme.
Further, on the basis of the above embodiment, the fault information is temporary fault information, and the fault information is displayed based on the dashboard in the step S404, which includes the following steps S4041 and S4042.
Step S4041, converting the temporary fault information into permanent fault information, wherein the clearing authority of the permanent fault information is higher than that of the temporary fault information.
Step S4042, displaying the permanent fault information based on the dashboard.
Specifically, when the engine cannot be started normally, the vehicle control system generates and stores the fault information in the memory as temporary fault information, and the temporary fault information can be automatically cleared when the vehicle control system determines that the engine has no system fault. When the engine has system faults, the whole vehicle control system converts the temporary fault information into permanent fault information and displays the permanent fault information on an instrument panel. The permanent fault information cannot be automatically cleared through the whole vehicle control system or actively cleared by a user, and a preset instruction can be triggered to clear only after maintenance personnel maintain the vehicle. It can be understood that the clearing authority of the permanent fault information is higher than that of the temporary fault information, and the clearing difficulty of the permanent fault information is higher and the clearing route is less compared with that of the temporary fault information.
Therefore, the embodiment limits that the vehicle control system stores temporary fault information in the memory, and converts the temporary fault information into permanent fault information when the system fault exists in the engine, and the fault information is prevented from being mistakenly cleared by setting the clearing authority, so that a user cannot know or forget that the fault exists in the vehicle in time.
Further, in a possible embodiment, when the tank level information rises in the above step S300, the control method further includes the following steps S301 and S302 before monitoring the next start-up condition of the engine.
Step S301, if the tank level information is lower than the preset threshold and the engine cannot be started normally, setting the control state of the engine as a start prohibition flag.
And step S302, closing the starting authority of the engine according to the starting prohibition zone bit so as to prohibit the engine from being started again.
Specifically, when the oil amount of the oil tank is small and the engine cannot be started normally, in order to avoid mechanical damage caused by frequent start failure of the engine, the whole vehicle control system sends a start prohibition flag bit to the engine to close the start permission of the engine, and at the moment, the engine cannot be started again.
Further, on the basis of the above embodiment, when the tank level information rises in the above step S300, the control method further includes the following steps S303 and S304 before monitoring the next start-up condition of the engine.
And step S303, resetting the start prohibition flag bit to a normal start flag bit when the oil tank liquid level information rises.
Step S304, starting the starting authority of the engine according to the normal starting zone bit, and monitoring the starting condition of the engine next time.
Specifically, when the liquid level in the oil tank rises, the user is stated that the vehicle is refueled at the moment, the influence on the engine caused by the fact that the oil amount is too small before is eliminated, then the whole vehicle control system sends a normal start flag bit to the engine to start the starting authority of the engine, at the moment, the engine is in a state capable of being started, and the starting condition of the next engine is monitored to judge whether the engine has a system fault or not.
Therefore, the above embodiment adjusts the starting authority of the engine by setting the normal starting zone bit and prohibiting the starting zone bit, so that the mechanical damage caused by frequent starting failure of the engine under the condition of too little oil quantity is avoided, and the practicability of the technical scheme is improved.
Further, in a possible embodiment, when the tank level information rises in the above step S300, the next start condition of the engine is monitored, including the following steps S305 and S306.
Step S305, monitoring the tank level information.
And step S306, when the oil tank liquid level information rises to reach the preset threshold value, monitoring the starting condition of the engine next time.
In this embodiment, when the liquid level in the oil tank rises to a preset threshold, that is, when the oil amount in the oil tank reaches a certain value, the whole vehicle control system determines that the oil amount in the oil tank meets the engine starting condition at this time, so that the next starting condition of the engine is monitored, so as to determine whether the engine has a system fault according to whether the engine can be started normally.
Further, in a possible embodiment, the control method of the hybrid electric vehicle of the present application further includes the following step S501 and step S502.
In step S501, if the tank level information is lower than the preset threshold and the engine cannot be started normally, the hybrid electric vehicle is adjusted to a pure electric mode.
Step S502, controlling the hybrid electric vehicle to drive by means of electric energy according to the pure electric mode.
Specifically, when the tank level information is lower than a preset threshold, i.e. the amount of oil in the tank is small, and the engine cannot be started normally, the vehicle is controlled to be in a pure electric mode, i.e. the vehicle is driven by electric energy provided by a battery at the moment, and the engine is not controlled to provide power.
Further, in a possible embodiment, the control method of the hybrid electric vehicle of the present application further includes the following step S601 and step S602.
And step S601, after generating fault information for temporary storage, determining that the vehicle has a system fault when abnormal operation conditions of other vehicle modules different from the engine are detected.
And step S602, when the system fault exists in the vehicle, displaying the temporary storage fault information based on a dashboard.
Specifically, when the vehicle control system generates fault information according to the condition that the engine cannot be started normally and stores the fault information in the memory, if abnormal operation conditions of other vehicle modules different from the engine, such as a driving motor module, an air conditioning module or an oil tank module, are detected, the system fault of the vehicle is determined, and the fault information temporarily stored before is displayed on an instrument panel so as to remind a user to check and maintain the vehicle in time.
So, in this embodiment, when there is the abnormal operation condition in other vehicle modules that are different from the engine, the trouble information that keeps in before will show to can avoid the oil mass too little to lead to trouble information misinformation, can remind the user when there are other abnormal conditions in the vehicle again, improve the practicality of this application technical scheme.
Fig. 4 shows an application flowchart of an embodiment of the present application, encompassing steps S411 to S420 as follows.
In step S411, the tank oil level sensor monitors the amount of the tank oil and feeds the oil amount information back to the vehicle control system.
And step S412, when the liquid level in the oil tank is extremely low, a warning of low oil amount is sent to a user in the form of a text prompt on the combination meter.
And step S413, judging that the electromechanical coupling system normally operates and has no system fault if the engine does not receive a starting instruction when the liquid level in the oil tank is extremely low, namely the engine starting condition is not met.
Step S414, if the engine receives the starting instruction and can be started normally, the electromechanical coupling system is judged to operate normally, and no system fault exists.
In step S415, if the engine receives a start command and the start fails, the electromechanical coupling controller records the current engine start failure information and temporarily stores the information in the ROM memory, and sends a start prohibition flag bit to the engine to prohibit the engine from being restarted, and forces the vehicle to enter the EV mode (pure electric mode).
In step S416, the electromechanical coupling controller latches the state of the current extremely low level in the fuel tank, and measures whether the fuel tank is subsequently replenished with fuel using the state as a standard.
In step S417, the level in the tank is continuously monitored.
In step S418, if it is detected that the fuel tank is replenished with fuel, a normal start flag bit is sent to the engine to reset the previously prohibited start flag bit, allow the engine to start again, and monitor the next engine start condition.
In step S419, if the engine is started successfully, it is determined that the engine has failed to start due to the insufficient oil amount, the engine itself has no failure, the engine start failure information stored in the ROM memory is cleared, and the vehicle operation is resumed.
Step S420, if the engine fails to start, determining that the engine has a fault, prompting the system fault through an instrument, reminding a user of contacting maintenance, and storing the engine start failure information stored in a ROM as permanent fault information, wherein the permanent fault information can only be cleared according to a maintenance command triggered by a maintenance person.
