Fig. 1 is a flowchart of a brake pedal failure processing method according to one embodiment of the present application, which is applied to a vehicle, as shown in fig. 1, and includes the steps of:
step S101, fault detection is carried out on the brake pedal, and a fault detection result is obtained.
Specifically, a vehicle comprises a brake pedal, and the method provided by the application firstly needs to detect faults of the brake pedal to determine whether the brake pedal has faults.
In the present application, the failure detection of the brake pedal is directed to a mechanical switch failure of the brake pedal. The tail end of the brake pedal connecting rod is provided with two mechanical switches, namely a main brake switch and an auxiliary brake switch, one is a normally closed switch, and the other is a normally open switch. Normally, the two are mechanically linked, and the states of the two are kept opposite and mutually exclusive. When a driver presses the brake pedal, the brake pedal can simultaneously touch the two switches, and the states of the two switches can be changed, namely the normally closed switch is switched to be opened, and the normally open switch is switched to be closed. The vehicle main controller verifies whether the input of the brake pedal opening is authentic by checking the difference between the two. When the two are not mutually exclusive, the brake system is indicated to have faults, the opening degree of the brake pedal is also unreliable, and at the moment, the vehicle main controller cannot accurately infer the driving intention of a driver, so that traffic accidents are easy to cause.
And step S102, responding to the fault detection result to indicate that the brake pedal is in fault, and recording the fault duration of the fault.
Specifically, if a brake pedal failure is detected, recording of the duration of the current failure state of the brake pedal is started. Each time a brake pedal fails, the time at which the failure occurred is recorded.
Step S103, in response to the fault duration being greater than the first preset duration, updating the preset statistic value to obtain the current statistic value.
The preset statistical value is used for representing the occurrence times of faults in one driving cycle, and the vehicle is in one driving cycle from starting to flameout.
In particular, a fault is considered to be truly occurring rather than a false positive or an impending fault when the duration of the fault is greater than a first predetermined duration. And after determining that the fault is actually generated, adding one to the preset statistical value to obtain the current statistical value. The current statistic is used to indicate the number of times the vehicle has failed the brake pedal at the current time.
It should be noted that the first preset duration may be set according to actual requirements, and the first preset duration is 1 second as an example.
It should be noted that, the preset statistic value is used for recording the occurrence times of faults of the brake pedal in one driving cycle, the default value can be set to 0, and the preset statistic value is updated once each time the brake pedal has faults, the current statistic value is obtained after the preset statistic value is updated for the first time, and the subsequent updating is performed based on the data of the current statistic value.
Step S104, comparing the current statistical value with a preset threshold value to obtain a comparison result.
Specifically, each time a fault occurs in the brake pedal, the numerical value of the current statistical value is updated, and after each update of the current statistical value, the current statistical value is compared with a preset threshold value to obtain a comparison result.
Step S105, controlling the vehicle by using the preset fault handling measure in response to the comparison result indicating that the current statistical value is greater than the preset threshold.
Specifically, if the comparison result indicates that the current statistical value is greater than the preset threshold value, the number of times of occurrence of the fault of the brake pedal is greater than the preset threshold value in the current driving cycle of the vehicle. When the occurrence times of the faults of the vehicle brake pedal are larger than a preset threshold value, determining that the faults are truly generated and have higher occurrence frequency, and not misinformation of the faults caused by the fact that the vehicle is in a special working condition, and further controlling the vehicle by using preset fault processing measures.
In the embodiment of the application, the fault detection is carried out on the brake pedal to obtain a fault detection result; responding to the fault detection result to indicate that the brake pedal is in fault, and recording the fault duration of the fault; in response to the duration of the fault being greater than a first preset duration, updating a preset statistic to obtain a current statistic, wherein the preset statistic is used for representing the occurrence times of the fault in one driving cycle, and the vehicle is turned off from start to stop to one driving cycle; comparing the current statistical value with a preset threshold value to obtain a comparison result; and responding to the comparison result to indicate that the current statistical value is larger than a preset threshold value, and controlling the vehicle by using a preset fault handling measure. The application carries out double judgment on the duration time of the fault and the occurrence frequency of the fault, so that the result of the fault detection of the brake pedal is more accurate, and the technical problem of higher false alarm rate of the existing fault detection method can be solved.
The problem of erroneous failure is likely to occur when the brake pedal is at a specific position due to manufacturing process errors, mechanical assembly reasons, driving habits, and the like. According to the application, through double judgment of the duration time and the occurrence times of the faults, the possibility of false alarm of the faults can be effectively reduced, and the fault detection result is more accurate.
Optionally, performing fault detection on the brake pedal, where obtaining a fault detection result includes: acquiring a power-on state of a vehicle, wherein the power-on state comprises power-on and power-off; and responding to the power-on state to power on, and performing fault detection on the brake pedal to obtain a fault detection result.
Specifically, when the brake pedal is detected by failure, it is first required to determine that the vehicle is in a powered-on state, because if the vehicle is in a powered-off state, the driver has no driving requirement, and at this time, it is meaningless to detect the failure of the brake pedal. When the vehicle is in a power-on state, the brake pedal can be subjected to fault detection, and a fault detection result is obtained.
Optionally, the brake pedal failure processing method further includes: and recording a fault code corresponding to the fault in response to the fault duration being greater than the first preset duration.
Specifically, when the duration of the fault is greater than the first preset duration, it indicates that the duration of the fault is longer and cannot be ignored, so that the fault code corresponding to the fault is recorded. When the vehicle is maintained, the vehicle can be maintained in a targeted mode according to the recorded fault code.
Optionally, the preset fault handling measures include: outputting fault prompt signals, controlling the torque of the driving motor to be cleared, and controlling the engine and the generator to be closed.
Specifically, the preset fault handling measures in the control of the vehicle by utilizing the preset fault handling measures comprise the steps of outputting a fault prompting signal, controlling the torque zero clearing of the driving motor and controlling the closing of the engine and the generator. The fault prompting information is output and comprises a system fault lamp which is turned on, the fault information is pushed to a remote terminal which is bound with the vehicle, and a control instrument panel sends out fault prompt.
Optionally, the brake pedal failure processing method further includes: in response to the failure duration being less than or equal to a first preset duration, performing the steps of: and performing fault detection on the brake pedal to obtain a fault detection result.
Specifically, when the recorded duration of the fault is less than or equal to the first preset duration, the duration of the fault is short, and the fault is possibly misreported, so that the fault is ignored, and the fault detection is performed on the brake pedal again, so that a fault detection result is obtained.
It can be understood that the fault duration is compared with the first preset duration, and then the next step is determined according to the comparison result, so that the false alarm fault with extremely short duration can be effectively filtered.
Optionally, the brake pedal failure processing method further includes: and responding to the comparison result to indicate that the current statistical value is smaller than or equal to a preset threshold value, and recording a fault code corresponding to the fault.
Specifically, when the comparison result shows that the current statistical value is smaller than or equal to the preset threshold value, namely the occurrence times of faults are small, and false alarm possibility exists, the fault code corresponding to the current fault is recorded, and additional control on the vehicle is not needed.
Optionally, the brake pedal failure processing method further includes: and controlling the vehicle with the preset fault handling means in response to the fault duration being greater than a second preset duration, wherein the second preset duration is greater than the first preset duration.
Specifically, when the duration of the fault is greater than the second preset duration, the duration of the fault is indicated to be too long, and intervention of preset fault handling measures is required to ensure safety of the vehicle and the driver.
For example, if the first preset duration is 1 second, the second preset duration may be set to 10 seconds.
It should be noted that the second preset duration may be set according to actual requirements.
In some embodiments of the present application, a brake pedal failure handling method includes: firstly, judging whether the vehicle is in a power-on state, and continuously judging whether the vehicle is in the power-on state when the vehicle is not in the power-on state. When the vehicle is in a power-on state, fault detection is carried out on the brake pedal, whether a fault detection result meets the condition A is judged, if the fault detection result does not meet the condition A, the fault detection is continuously carried out on the brake pedal, and whether the fault detection result meets the condition A is judged. And if the condition A is met, executing the measure A. And judging whether the condition B is satisfied, and executing the condition A if the condition B is not satisfied. And if the condition B is met, executing the measure B.
It should be noted that, the condition a is that the duration of the fault is greater than 1 second, and the condition B is that the number of faults exceeds the preset 20 times in one driving cycle. The measure A is to store the fault code corresponding to the fault, the measure B is to light the system fault lamp, push the fault prompt information, control the instrument to send out the fault prompt, control the torque of the front and rear driving motor to clear and control the engine and the generator to stop.
From the description of the above embodiments, it will be clear to a person skilled in the art that the method according to the above embodiments may be implemented by means of software plus a necessary general hardware platform, but of course also by means of hardware, but in many cases the former is a preferred embodiment. Based on such understanding, the technical solution of the present application may be embodied essentially or in a part contributing to the prior art in the form of a software product stored in a storage medium (e.g. ROM/RAM, magnetic disk, optical disk) comprising instructions for causing a terminal device (which may be a mobile phone, a computer, a server, or a network device, etc.) to perform the method according to the embodiments of the present application.
