Embodiment Construction
[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. All other embodiments obtained on the premise of the embodiments of the present invention belong to the protection scope of the present invention.
[0041] In one embodiment, as figure 1 As shown, a method for updating a program of a motor controller is provided, which specifically includes the following steps:
[0042] S10: After the motor controller is powered on, check the integrity of the application program of the motor controller before running the application program.
[0043] After the motor controller is powered on and the hardware is initialized, before running the application program of the motor controller, it is necessary to check the integri...

The invention discloses a program updating method and device of motor controller, and a readable storage medium. Integrity verification is carried out on an application program of the motor controller after the motor controller is powered on and before the application program is operated, and if the application program of the motor controller does not pass the integrity verification, a software flashing mode is entered to update the application program. The integrity verification is performed on the application program before the application program runs, and if the integrity verification is not passed, the software flashing mode is entered to update the application program, so that the risk that the application program cannot run due to the incomplete program is reduced, and the risk that the program cannot be updated by using a diagnostic instrument after the application program runs is reduced, therefore, the motor controller does not need to be subjected to uncovering updating or forced brushing by using a special tool, the updating efficiency of the software of the motor controller is greatly improved, the time and the cost are saved, and the updating requirement of the software of the motor controller is quickly and efficiently met.
Description
technical field [0001] The invention relates to the technical field of vehicle control, in particular to a program updating method, device and readable storage medium for a motor controller. Background technique [0002] After the loading and debugging of the vehicle motor controller in the later stage of development and the mass production of the vehicle, it will be found that the function or performance of the motor controller needs to be improved in time, so the software (application program) of the motor controller must be updated to ensure that the motor controller Full-featured and reliable. The traditional software update of the motor controller is mainly updated by using a diagnostic instrument. If external interference occurs during the software update process of the diagnostic instrument and the program update is interrupted, the software update will fail, which will cause the software in the controller to be incomplete, resulting in The controller cannot work nor...
