Abstract

The invention relates to an ECU application program updating method, device and system, a storage medium and electronic equipment, belongs to the field of vehicles, and can realize stable and reliable updating of an ECU application program. The ECU application program updating method comprises the following steps: acquiring an ECU application program updating data packet from a vehicle-mounted information box; the ECU application program updating data packet is analyzed; a flash memory erasing program is called from the vehicle-mounted information box, a first flash memory area of the ECU is erased, and the first flash memory area is a storage area used for burning the ECU application program updating data packet on the first flash memory area; and burning the ECU application program updating data packet obtained by analysis to the erased first flash memory area.

Description

technical field [0001] The present disclosure relates to the field of vehicles, and in particular, to a method, apparatus, system, storage medium and electronic device for updating an ECU application program. Background technique [0002] At present, the process of remotely updating the application program of the on-board electronic control unit (ECU) is mainly as follows: the on-board telematics box (T-box), also known as the on-board terminal, downloads a new version of the ECU from the cloud application, and then distribute the new version of the ECU application to the corresponding ECU, and then the ECU performs the update task. The disadvantage of this remote update process is that the update is prone to errors or failures. SUMMARY OF THE INVENTION [0003] The purpose of the present disclosure is to provide an ECU application program updating method, device, system, storage medium and electronic device, which can realize stable and reliable updating of the ECU appli...
