[0081] Based on the above-mentioned first embodiment, before the step S30, the vehicle-mounted computer software upgrading method of this embodiment also includes:

[0082] Step S21: Obtain the preset number of flashing times corresponding to the product identification information.

[0083] It should be noted that the preset number of times of flashing is a preset number of times used to indicate that repeated flashing is required.

[0084] Correspondingly, step S30 in this embodiment specifically includes:

[0085]Step S30': Based on the preset flashing times, repeatedly upgrade the software of the vehicle-mounted computer to be upgraded according to the bus protocol, the startup and loading process, and the program format.

[0086] It should be noted that during the development process, the number of repeated flashing times can be set through the preset number of flashing times, and then based on the preset number of refreshing times, the software of the vehicle-mounted com...

Abstract

The invention belongs to the technical field of vehicle software, and discloses a vehicle-mounted computer software upgrading method, a device and equipment and a storage medium. The method comprisesthe steps of obtaining product identification information of a to-be-upgraded vehicle-mounted computer; determining a corresponding bus protocol, a starting loading process and a program format according to the product identification information; and upgrading the software of the to-be-upgraded vehicle-mounted computer according to the bus protocol, the startup loading process and the program format. The corresponding bus protocol, the starting loading process and the program format can be obtained only through the product identification information corresponding to the vehicle-mounted computer aiming at different vehicle-mounted computers, and then the software of the vehicle-mounted computer can be upgraded according to the bus protocol, the starting loading process and the program format, so that unnecessary repeated work in software upgrading is reduced, the software upgrading efficiency is improved, and convenience is provided for software upgrading of the vehicle-mounted computer.

Description

technical field [0001] The invention relates to the technical field of vehicle software, in particular to a method, device, equipment and storage medium for upgrading software of a vehicle computer. Background technique [0002] Nowadays, with the continuous development of electronic technology, there are more and more on-board computers (Electronic Control Unit, ECU) with embedded systems on the vehicle, and even a vehicle contains dozens of different ECUs at the same time, and when the ECU software When there is a loophole or needs to be optimized, it is necessary to upgrade the ECU software through the boot loader (Bootloader). Since the Bootloader process, communication protocol, and program format of each ECU are not completely consistent, it is necessary to develop different upgrade equipment to upgrade each ECU, and there are many repetitive tasks. [0003] The above content is only used to assist in understanding the technical solution of the present invention, and ...
