It should be noted that the present method is applied to a vehicle including a plurality of assemblies and an overall controller.
FIG. 1 is a flow chart of a vehicle assembly fault handling method according to one embodiment of the present application, as shown in FIG. 1, comprising the steps of:
step S101, for each preset signal category, detecting the communication state of the preset signal category to obtain a detection result.
In step S101, the detection result includes a communication state corresponding to each preset signal category, where the communication state is a communication state between a plurality of assemblies of the vehicle and the overall controller, and the communication state includes normal and abnormal states.
Specifically, the preset signal category is a category corresponding to communication signals between the plurality of assemblies and the master controller, so that the communication state is a communication state between the plurality of assemblies of the vehicle and the master controller.
It should be noted that, the signal corresponding to the preset signal category is sent by the vehicle assembly, and is used for reporting the signal of the failure index of the assembly to the overall controller, and when the assembly fails, the signal of the corresponding category is sent to the overall controller. It can be appreciated that when communication anomalies occur in signals corresponding to multiple preset signal categories, the overall controller cannot determine whether the assembly corresponding to the abnormal communication signal fails.
In an alternative embodiment of the present application, the preset signal categories include: the first signal is a signal corresponding to a thermal management function, the second signal is a signal affecting a high-voltage power-on and power-off function, and the third signal is a signal affecting a driving function. It should be noted that the preset signal category in this embodiment is specific to the motor assembly.
Specifically, in this embodiment, the fault corresponding to the thermal management function signal in the first signal includes: the temperature of the motor is too high or too low, and the temperature sensor of the battery is abnormal; the faults corresponding to the signals affecting the high-voltage power-on and power-off functions in the second signals comprise: the voltage detection of the inverter is abnormal, the voltage is over-voltage and under-voltage of 12V (volt), the voltage is over-voltage and under-voltage, and the three phases are over-current; the faults corresponding to the signals affecting the driving function in the third signal include: abnormal torque monitoring, power supply failure in the control panel, rotation failure, IGBT (insulated gate bipolar transistor) failure, and power supply chip failure of the control panel.
In an alternative embodiment of the present application, the preset signal class further includes: the system comprises a first signal, a second signal, a third signal, a fourth signal and a fifth signal, wherein the first signal is a first-level fault corresponding signal of the battery assembly, the second signal is a second-level fault signal of the battery assembly, the third signal is a third-level fault signal of the battery assembly, the fourth signal is a fourth-level fault signal of the battery assembly, and the fifth signal is a fifth-level fault signal of the battery assembly.
Specifically, in this embodiment, the battery assembly primary failure includes: the total voltage is seriously overhigh, the temperature is seriously overhigh, any contactor is adhered, and the relay fails; the battery assembly secondary failure includes: pre-charge verification fails, and SOC (state of charge) is protected from being too low; the three-stage fault of the battery assembly comprises: the monomer voltage is too high or too low; the battery assembly four-stage fault includes: the main part and the main part are adhered simultaneously; the five-stage fault of the battery assembly comprises: thermal runaway, battery crash damage.
Step S102, determining the fault level of the vehicle in response to the detection result indicating that the communication state with the preset signal category is abnormal.
Specifically, if the detection result indicates that the preset signal category with abnormal communication state exists, the detection result indicates that at least one assembly and the overall controller have abnormal communication state, and normal communication cannot be performed between the assembly and the overall controller. At this time, the failure level of the vehicle is determined according to the type of the preset information in which the abnormality occurs.
Step S103, determining fault handling measures according to the fault level.
Specifically, in the vehicle, the same fault handling measures are preset for different fault classes, and after the fault class is determined in step S102, the fault handling measures can be further determined according to the fault class.
Step S104, controlling the vehicle according to the fault handling measures.
Specifically, after determining that the fault handling measures are obtained in step S103, the vehicle is controlled according to the fault handling measures.
Optionally, in some embodiments of the present application, the fault handling means comprises one or more of: storing fault codes, limiting driving power, clearing driving torque, prompting fault information, limiting vehicle speed and prohibiting automatic driving functions.
It will be appreciated that the fault handling measures are different for different fault classes.
For the motor assembly, if the fault level of the vehicle is the fault level corresponding to the first signal, the fault handling measures are to store the fault code, limit the driving power and prompt fault information. If the fault level of the vehicle is the fault level corresponding to the second signal, the fault handling measures are to store the fault code, clear the driving torque, prompt the fault information and prohibit the automatic driving function. If the fault level of the vehicle is the fault level corresponding to the third signal, the fault processing measures are that the fault code is stored, the driving torque is cleared, the vehicle speed is limited to 0, the fault information is prompted, and the automatic driving function is forbidden.
In the embodiment of the application, aiming at each preset signal category, detecting the communication state of the preset signal category to obtain a detection result, wherein the detection result comprises the communication state corresponding to each preset signal category, the communication state is the communication state between a plurality of assemblies of the vehicle and a master controller, and the communication state comprises normal and abnormal; responding to the detection result to indicate that the communication state with the preset signal category is abnormal, and determining the fault level of the vehicle; determining fault treatment measures according to the fault level; the vehicle is controlled according to the fault handling measures. According to the application, the communication states between the plurality of control assemblies and the master controller are detected, and then the vehicle fault grade is determined according to the detection result, so that the effect of determining the vehicle fault grade when the key assembly and the master controller have communication faults can be achieved, and the technical problem that the key assembly and the related controller have communication faults, and the key assembly cannot receive accurate signals, so that the problem occurs in the vehicle fault processing process can be solved.
It can be understood that in the embodiment provided by the application, when communication between any assembly and the overall control is abnormal, whether the assembly fails or not and what type of failure occurs cannot be judged, the assembly is directly considered to fail, and the type of the failure is determined according to the abnormal preset signal type.
Optionally, in step S102, in response to the detection result indicating that the communication state in which the preset signal class exists is abnormal, determining the failure level of the vehicle may include the steps of:
in step S1021, in response to the detection result indicating that the communication state in which the preset signal class exists is abnormal, the preset signal class in which the communication failure occurs is marked as the failure signal class.
Step S1022, determining the fault level corresponding to the fault signal category according to the fault signal category.
Specifically, in this embodiment, when it is detected that the communication state of the corresponding signal having the preset signal category is abnormal, the corresponding signal of the preset signal category in which the abnormality has occurred is marked as a fault signal category, and then a fault level corresponding to the fault signal category in the vehicle is determined according to the fault signal category.
It is understood that in the vehicle, for each of the preset signal categories, a corresponding failure level is set.
Optionally, in step S102, in response to the detection result indicating that the communication state in which the preset signal class exists is abnormal, determining the failure level of the vehicle may include the steps of:
in step S102a, in response to the detection result indicating that the communication state in which the preset signal class exists is abnormal, a plurality of preset signal classes in which communication failure occurs are marked as failure signal classes.
Step S102b, for each fault signal category, determining a preset level corresponding to the fault signal category, and obtaining a plurality of preset levels.
In step S102c, a maximum value of the plurality of preset levels is determined as the failure level.
Specifically, in this embodiment, if the detection result indicates that there are a plurality of preset signal categories in which a fault occurs, each preset signal category in which a communication fault occurs is marked as a fault signal category, and a plurality of fault signal categories may be obtained. And then, aiming at each fault signal category, determining a preset grade corresponding to the fault signal category, and further obtaining a plurality of preset grades. And then selecting the maximum value from the plurality of preset grades as the fault grade.
It should be noted that, the detection result indicates that the plurality of preset signal categories fail, which is specific to one vehicle assembly, that is, the plurality of preset signal categories corresponding to one vehicle assembly fail.
Optionally, in some embodiments of the present application, the preset levels are in one-to-one correspondence with the fault signal categories.
Optionally, the vehicle assembly fault handling method further includes: after the step of controlling the vehicle according to the fault handling measures, the following steps are performed:
step S1041, monitoring the communication state of the preset signal class with the communication fault, and obtaining a monitoring result.
In step S1042, in response to the monitoring result indicating that the communication state of the preset signal class is normal, the exit condition of the fault handling measure is determined according to the preset signal class.
In step S1043, in response to the vehicle meeting the exit condition, the vehicle exit fault handling means is controlled.
Specifically, when the vehicle is controlled according to the determined fault handling measures, it is also necessary to determine when the vehicle exits the corresponding fault handling measures. It will be appreciated that if the vehicle does not have a fault corresponding to the fault handling means, the vehicle needs to be controlled to exit the corresponding fault handling means.
If the preset signal type of the communication fault is the first signal, the communication state of the first signal is continuously monitored, when the state of the first signal is recovered from abnormal to normal, according to the fault processing measure exit condition corresponding to the first signal and synchronous with the fault, if the first signal indicates that the vehicle has no fault corresponding to the first signal, the exit condition is met, and the vehicle is controlled to exit the fault processing measure.
It should be noted that, for the motor assembly, the exit condition corresponding to the first signal is synchronous with the fault, and the exit conditions of the second signal and the third signal are that the vehicle is powered down and the fault disappears. For the battery assembly, the exit conditions corresponding to the first signal, the second signal and the third signal are synchronous with faults, and the exit conditions corresponding to the fourth signal and the fifth signal are that the vehicle is powered down and the faults disappear.
It will be appreciated that when the exit condition synchronized with a fault is interpreted as the failure disappearing, the corresponding failure handling measures exit synchronously. The exit condition of the vehicle power down and the failure disappearance is interpreted as that the corresponding failure handling measures can be exited when the vehicle power down and the failure vanish.
