Abstract

The invention provides a control method, device and equipment for flashing a program, and relates to the technical field of vehicles. The control method for flashing a program includes: detecting that the first controller on the first bus is in a state of waiting for flashing a program When the vehicle is powered on at high voltage by the second controller on the second bus; when the vehicle is in the state of high voltage power on, control the first controller which is in the state of the program to be flashed; When the above-mentioned first controller is in the state where the flashing program ends, the vehicle is controlled to be powered off at high voltage. In the embodiment of the present invention, when the first controller is in the state to be flashed, the second controller on the second bus controls the high-voltage power-on of the vehicle to charge the battery, so as to avoid flashing when the battery power is insufficient during the flashing process. fail.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a control method, device and equipment for flashing a program. Background technique [0002] With the intelligent development of automobiles, the application degree of electronic modules and software technology in the whole vehicle is also higher and higher. All the controllers of the whole vehicle can reach more than 80, but except for the intelligent driving controller and entertainment controller, other It is derived from the traditional car, but the traditional flashing method has a slow flashing speed, and the controllers are not allowed to communicate with each other during flashing, that is, all functions cannot be started, and the flashing time is long, and the vehicle battery cannot support it. All the controllers of the whole vehicle are remotely upgraded at the same time. At the same time, each user may not always have on-site battery charging equipment. [0003] Th...
