Abstract

The invention provides a flash program control method, device and equipment, and relates to the technical field of vehicles. The flash program control method comprises the steps: making a vehicle be powered on at a high voltage through a second controller on a second bus when a first controller on a first bus is detected to be in a state of a to-be-flashed program; when the vehicle is in a high-voltage power-on state, making the first controller in the state of a to-be-flashed program flash a program; and when the first controller is detected to be in the state that the flash program is finished, making the vehicle be powered off at the high voltage. According to the embodiment of the invention, when the first controller is in the state of the to-be-flashed program, the second controller on the second bus makes the vehicle be powered on at the high voltage to charge a storage battery so that flash failure caused by an insufficient electric quantity of the storage battery in a flash program process is avoided.

Description

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