Detailed Description
So that the manner in which the above recited objects, features and advantages of the present invention can be understood in detail, a more particular description of the invention, briefly summarized above, may be had by reference to the embodiments thereof which are illustrated in the appended drawings. It should be noted that the embodiments of the present invention and features of the embodiments may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.
The Vehicle controller may also be referred to as a Vehicle Control Unit (VCU), and is electrically connected to a BMS (Battery Management System) main Control board, a T-Box (Terminal Box), and an actuator, respectively.
As shown in fig. 1, a method for processing fault information of a vehicle controller according to an embodiment of the present invention includes:
step S102, responding to the operation signal of the vehicle controller, determining the operation mode corresponding to the operation signal, and detecting whether the operation fault in the operation mode is generated.
The operation mode of the vehicle controller may be divided according to the operation mode of the vehicle, and the operation mode of the vehicle may be divided according to the charge-discharge state of the vehicle, for example, when the vehicle is in a driving state or a parking state, the vehicle may be regarded as being in a discharge state.
In addition, the fault information may be stored in the form of a fault code, and after entering any operation mode, the fault detection is started, and if a fault is detected for the first time, the fault code may be recorded as the stored fault information matching the operation fault, and the fault identification position is set to 1.
Step S104, if it is detected that no operation fault is generated and fault information matched with the operation fault is stored, when the operation mode is ended, determining that the fault information is subjected to an aging period so as to increase the statistics of the aging period.
If the fault code is recorded, but the corresponding operation fault is not detected in the operation period, the fault identification position is set to be 0, and the fault information is considered to enter an aging state, if the operation fault is detected to be not generated for the first time, the statistical value is recorded as 1, and if the operation fault is detected to be not generated for multiple times, the statistical value is recorded as multiple times.
And step S106, deleting the fault information under the condition that the statistical value is greater than or equal to the preset threshold value.
And if the number of the operation faults which are not generated is continuously detected for multiple times and reaches a preset threshold value, clearing the confirmed fault code and deleting the fault information.
The fault information processing method provided by this embodiment determines the operation mode in which the vehicle controller is located when the vehicle controller operates, and only detects an operation fault that may occur in the operation mode, and at the end of the operation mode, may regard an operation cycle in the operation mode as completed, and if a stored operation fault is not detected in the operation cycle, it indicates that the operation fault is not reproduced in the operation cycle, and the operation cycle may also be regarded as an aging cycle of the operation fault.
If the operation fault still does not exist in the next operation period of the operation mode, accumulating the unrepeated times, namely the statistics of the aging period until the accumulated statistics is detected to be larger than or equal to the preset threshold value, indicating that the use value of the fault information of the operation fault is very small, and deleting the fault information.
The operation period in which the operation fault possibly occurs is recorded as the aging period, the period corresponding to the operation mode in which the operation fault possibly occurs is eliminated, the probability that the fault information is prematurely cleared can be reduced by combining a preset threshold value which is reasonably set, and the fault information can be more conveniently called when needed, so that the probability that the fault information is applied to vehicle maintenance is improved, and the stored fault information plays a role in assisting maintenance to the maximum extent.
In some embodiments, the determining the operation mode corresponding to the operation signal in response to the operation signal of the vehicle controller described in the above step S102 may be implemented by: detecting whether the operation signal is a power-on signal or a charging signal in response to the operation signal; if the operation signal is a power-on signal, determining that the corresponding operation mode is a driving mode; and if the operation signal is the charging signal, determining that the corresponding operation mode is the charging mode.
According to the working principle of the electric vehicle, the operation mode of the vehicle controller is divided into a driving mode and a charging mode, and the vehicle cannot be in the driving mode and the charging mode at the same time, so that the corresponding operation fault is detected in the mode, specifically, the vehicle controller is distinguished to be in the driving mode or the vehicle mode by detecting whether the operation signal is an electrifying signal or a charging signal, the detection mode is simple, and the reliability of the detection result is high.
In one implementation, a driving execution module is connected to the vehicle controller, and the driving mode is matched with an operation failure of the vehicle controller and an operation failure of the driving execution module.
The driving execution module comprises a battery management module BMS, a motor controller, an engine management module, a gearbox control module and the like.
The charging mode comprises an alternating current charging mode and a direct current charging mode, the vehicle controller is connected with an alternating current charging module and a direct current charging module, and the alternating current charging mode is matched with the operation fault of the vehicle controller and the operation fault of the alternating current charging module; the DC charging mode is matched with the operation fault of the vehicle controller and the operation fault of the DC charging module.
The alternating current charging module comprises a battery management module and an alternating current charging interface, and the direct current charging module comprises a battery management module, a direct current charging interface and the like.
In addition, as can be understood by those skilled in the art, part of the functional modules can be operated in a driving mode and a charging mode simultaneously, such as an on-board air conditioner, a window control module, and the like, so as to turn the fault into a conventional fault.
The conventional fault vehicle control unit has the fault related to the basic function, and the vehicle can be triggered when running or charging.
The driving type fault includes a partial operation fault of the vehicle controller and an operation fault of the driving execution module, and refers to a fault which may be generated only when the vehicle is driven and cannot be generated in a charging state.
The dc charging fault includes a partial operation fault of a vehicle controller and an operation fault of a dc charging module, and refers to a fault that may be generated only when a vehicle is dc charged and cannot be generated when the vehicle is driven or ac charged.
The ac charging type fault includes a partial operation fault of a vehicle controller and an operation fault of an ac charging module, and refers to a fault that may be generated only when the vehicle is ac charged and cannot be generated when the vehicle is driven or dc charged.
Specifically, the conventional fault takes the network activation to the network dormancy as the starting point and the end point of an operation cycle, the vehicle control unit starts to detect the fault when entering the working state, and takes the network cycle as the aging cycle of the conventional fault and counts an aging counter. The conventional fault does not consider that the vehicle running state is in a driving state, an alternating current charging state or a direct current charging state.
The driving fault is detected after the vehicle is powered on at high voltage, and the high-voltage power-on and power-off cycle is taken as the aging cycle of the driving fault and is counted in an aging counter. When the vehicle is in an AC charging state and a DC charging state, the faults of the vehicles are not detected, and the cycle does not include an aging counter.
The AC charging fault is detected by taking the AC charging wake-up to the AC charging end as the starting point and the ending point of an operation cycle, and the AC charging cycle is taken as an aging cycle of the AC charging fault and is counted in an aging counter. When the vehicle is in a running and direct current charging state, the alternating current charging fault is not detected, and the aging counter is not counted in the cycle.
And when the vehicle is awakened by the direct current charging, the fault is detected, and the direct current charging cycle is taken as an aging cycle of the direct current charging fault and is counted into an aging counter. When the vehicle is in a running and alternating current charging state, the direct current charging fault is not detected, and the aging counter is not counted in the cycle.
As shown in fig. 2, another method for processing fault information of a vehicle controller according to an embodiment of the present invention includes:
step S202, responding to the operation signal of the vehicle controller, determining the operation mode corresponding to the operation signal, and detecting whether the operation fault in the operation mode is generated.
Step S204, if the generation of the operation fault is detected, whether fault information matched with the operation fault is stored or not is inquired.
In step S206, if it is determined that the fault information has been stored, a clear operation is performed on the statistical value to recount the aging period.
In step S208, if it is determined that the failure information is not stored, the failure information is stored.
The method comprises the steps of determining whether an operation fault occurs for the first time or not by inquiring whether fault information generating the operation fault is stored or not, directly storing the fault information if the operation fault occurs for the first time, setting the identification position of the fault information to be 1, and directly resetting the energy quantity of the statistics to be recounted if the operation fault does not occur for the first time, wherein the probability of the operation fault is high, the fault identification position is set to be 1, so that the storage time of the fault information matched with the operation fault is prolonged, and the method is convenient for inquiring and is beneficial to calling maintenance reference.
Step S210, if it is detected that no operation fault is generated and fault information matching the operation fault is already stored, when the operation mode is ended, it is determined that the fault information has undergone an aging period, so as to increase the statistics of the aging period.
In step S212, if it is detected that the statistic is greater than or equal to the preset threshold, the fault information is deleted.
In the embodiment of the invention, when the vehicle is abnormal, the fault code is an important clue for troubleshooting, and more fault information is stored under the condition of permission of the memory of the electronic control unit so as to reduce the maintenance difficulty of the vehicle.
