Embodiment Construction

[0048] When the controller is installed on the corresponding application product, the controller needs to be flashed according to the requirements of the application product, such as flashing the program and data corresponding to the application product, so that the controller can realize the specific function of the application product. Usually, the controllers of the same type of application products need to flash the same content. When it is necessary to flash the controllers of a large number of application products, the single-line flashing method is inefficient and prone to flashing inconsistencies.

[0049] In order to solve this problem, this application provides a method for flashing a controller, a controller, and a host computer. In this solution, each controller for flashing needs to use a different source address, so that the host computer can distinguish each controller according to the source address. It avoids the phenomenon that multiple controllers use the sam...

Abstract

This application provides a controller flashing method, a controller and a host computer. After each controller establishes communication with the host computer, the host computer sends an address acquisition command to each controller, and each controller returns an address statement containing the source address to the host computer. message. At the same time, each controller receives the address declaration message sent by other controllers, and compares whether its own source address conflicts with the source address of other controllers. The controller that assigns the source address. The controller that needs to re-allocate the source address re-assigns itself a new source address that does not conflict with other controllers, and reports it to the host computer. After the upper computer confirms that the source addresses of each controller do not conflict with each other, it flashes each controller at the same time. Finally, multiple controllers can be flashed at the same time, which improves the flashing efficiency and ensures the consistency of the controller flashing.

Description

technical field [0001] The invention belongs to the technical field of vehicle control, and in particular relates to a controller flashing method, a controller and an upper computer. Background technique [0002] Controller flashing refers to flashing the program, data, etc. of the controller to enable the controller to achieve specific functions. [0003] The current controller flashing adopts a one-to-one flashing method between the host computer flashing tool and the controller, that is, single-point flashing. Communication, data interaction. When there are a large number of controllers that need to be flashed, each controller needs to perform a flashing operation repeatedly, so the efficiency of the single-point flashing method is low, and different operators or different flashing environments are prone to flashing. Write inconsistent cases. Contents of the invention [0004] In view of this, the object of the present invention is to provide a controller flashing me...
