Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating embodiments of the invention, are given by way of illustration and explanation only, not limitation. In addition, the embodiments of the present invention and the features of the embodiments may be combined with each other without conflict.
Faults caused by failure of configuration data of the vehicle controller bring serious harm to the running of the vehicle, so that setting a reasonable safety mechanism for the configuration data of the vehicle controller becomes more and more important. Based on the above, the embodiment of the invention provides a storage method and device and a use method and device of configuration data of a vehicle to provide a storage safety mechanism and a use safety mechanism for the configuration data.
Fig. 1 shows a flow chart of a storage method of configuration data of a vehicle according to an embodiment of the present invention. As shown in fig. 1, an embodiment of the present invention provides a method for storing configuration data of a vehicle, where the vehicle may be any type of vehicle, such as an electric vehicle or a hybrid vehicle, and the embodiment of the present invention mainly takes the vehicle as an electric vehicle, and then the configuration data is configuration data of a vehicle control unit for the electric vehicle. The method may include: step S110, performing preset operation on configuration data to be stored; step S120, storing the configuration data to be stored and the data obtained after the preset operation into a storage area of the vehicle; and step S130, detecting the data stored in the storage area to determine the safety of the storage area.
The preset operation may be, for example, a complement operation or an inverse operation, and the detection method used in step S130 may be a cyclic redundancy check method, or may be any other suitable check method, for example, a parity check, and the like.
The embodiment of the present invention will be specifically described below by taking an example in which the preset operation is a complement operation and the detection method used in step S130 is a cyclic redundancy check method.
When developing the vehicle control unit, the configuration data may be set corresponding to functions that need to be implemented (e.g., an auto cruise function, a cruise control function, or the like). Since electric vehicles are generally required to implement a plurality of functions, each function may require one or more configuration data, and thus, a corresponding plurality of configuration data needs to be stored. The complement operation is performed for each configuration data that needs to be stored. After the complement operation, the complement data of each configuration data can be obtained.
Each configuration data and the complement data of each configuration data to be stored may be stored later, for example, may be stored in a fixed storage area of a vehicle control unit of the pure electric vehicle, where the fixed storage area is generally a read-only storage area.
After the storage is completed, the cyclic redundancy check method can be used for periodically detecting the data stored in the storage area to determine the safety of the storage area. Optionally, a cycle of performing detection on the data in the storage area should be smaller than a fault tolerance time interval of the storage area, the fault tolerance time interval may be obtained through detection at an initial stage of software development of the vehicle controller, and may be considered as a fixed value, and a set value of the cycle of performing detection on the data in the storage area should be smaller than the fixed value.
In performing detection, a cyclic redundancy check may be performed on a bit-by-bit basis, e.g., a cyclic redundancy check may be performed every predetermined bit (e.g., every eight bits) of data stored in a storage area. And acquiring the check code obtained after each cyclic redundancy check, judging whether the check code is the same as the corresponding preset check code, if so, determining that the storage area is safe, otherwise, determining that the storage area is abnormal. Under the condition that the storage area is determined to be abnormal, the vehicle control unit can control the storage area to reset, and continuously execute cyclic redundancy check after resetting, or the vehicle control unit can send out related prompt information of storage area faults, so that maintenance of workers is facilitated.
It is to be understood that the above-described implementation is illustrative only and is not limiting upon the embodiments of the present invention. The process of performing an inverse operation or detecting the data area using a parity method may be performed similarly to the above-described process.
The storage method of the configuration data of the vehicle provided by the embodiment of the invention provides a safe storage mechanism for the configuration data, and ensures the safety in the storage process of the configuration data.
Fig. 2 shows a flow diagram of a method for using configuration data of a vehicle according to an embodiment of the invention. As shown in fig. 2, an embodiment of the present invention further provides a method for using configuration data of a vehicle, where the configuration data may be configuration data stored according to a storage method of configuration data of a vehicle according to any embodiment of the present invention. Similarly, the vehicle may be any type of vehicle, such as an electric vehicle or a hybrid vehicle, and the embodiment of the present invention is mainly described by taking the vehicle as an electric vehicle, so that the configuration data is configuration data of a vehicle controller for the electric vehicle. The method of using the configuration data for the vehicle may include steps S210 to S230.
In step S210, in a case where the storage area of the vehicle is safe, the configuration data to be used and the data obtained by the preset operation corresponding to the configuration data to be used are read from the storage area.
Before the function application function of the electric vehicle calls the corresponding configuration data, the safety of the storage area needs to be determined first, and for example, whether the storage area is safe or not can be determined by the result fed back after the last cyclic redundancy check. If the memory area is abnormal, which indicates that the data stored in the memory area is not necessarily accurate, the data cannot be read from the memory area. In this case, after waiting for a preset time, it may be determined again whether the storage area is recovered to normal, if so, the data may be read from the stored data, otherwise, the vehicle controller may send out a prompt message related to a failure of the storage area, so as to facilitate maintenance by a worker.
In step S220, the read configuration data that needs to be used and the data obtained after the preset operation corresponding to the configuration data that needs to be used are verified by using the preset operation to obtain a verification result.
For example, if the predetermined operation is a complement operation, the read configuration data to be used may be subjected to an inverse operation, and it may be determined whether the data after the inverse operation is identical to the inverse data read from the memory. If the two are the same, the verification result indicates that the verification is passed. If the two are not the same, it indicates that an exception may occur during the data reading process, in which case the verification result indicates that the verification fails. The execution of the complement operation is similar to the execution of the complement operation.
Step S230, if the verification result indicates that the verification passes, using the read configuration data.
And only in the case that the verification result indicates that the verification is passed, the function application function of the electric vehicle configures the corresponding function by using the configured data.
Further, if the verification result indicates that the verification is not passed, the vehicle control unit may be started to perform a fault handling operation. For example, the vehicle control unit may be triggered to perform the reset operation, but the reset operation of the vehicle control unit cannot be taken as a safe state, and thus, the number of times the reset operation of the vehicle control unit is performed needs to be limited.
Specifically, when the failure processing operation needs to be performed, it may be determined whether the number of times that the vehicle control unit of the vehicle performs the reset operation reaches a preset number of times. Here, the calculation of the number of times the vehicle control unit performs the reset operation is for the configuration data that is currently read, regardless of the number of times the reset operation is performed before the configuration data is currently read. The preset number of times may be set to any suitable value according to actual needs, and the embodiment of the present invention is not particularly limited.
If the number of times that the vehicle control unit of the vehicle executes the reset operation does not reach the preset number of times, the vehicle can be triggered to execute the reset operation. After the execution of the reset operation of the vehicle is completed, steps S210 to S230 are executed again. If the verification result again indicates that the verification failed, the failure handling operation may be performed again.
If the number of times of the vehicle controller of the vehicle executing the reset operation reaches the preset number of times, it indicates that the normal operation of the vehicle controller cannot be recovered through the reset operation at present, and under the condition, the emergency shutdown path of the vehicle controller can be triggered, so that the vehicle controller enters a safe state, and the vehicle is prevented from being dangerous.
According to the method for using the configuration data of the vehicle, provided by the embodiment of the invention, on the premise of determining the storage safety of the configuration data, the configuration data and the corresponding data after the preset operation are read from the storage area, the read data are verified, and the configuration data are only applied under the condition that the verification is passed. That is, a safe-to-use mechanism is provided for configuration data that cooperates with a safe-to-store mechanism to ensure that the configuration data is safe and correct to meet the safety-level requirements of the vehicle.
