Problems solved by technology

When a large number of controllers 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 inconsistencies

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

The invention provides a controller flashing method, a controller and an upper computer. After each controller establishes communication with the upper computer, the upper computer sends an address acquisition instruction to each controller, and each controller returns an address declaration message containing a source address to the upper computer. Meanwhile, each controller respectively receivesthe address declaration messages sent by other controllers, compares whether the own source address conflicts with the source addresses of other controllers or not, and determines the controller to which the source address needs to be reallocated according to the sequence of sending the address declaration messages if the own source address conflicts with the source addresses of other controllers. The controller which needs to reallocate the source address reallocates a new source address which does not conflict with other controllers and reports the new source address to the upper computer.The upper computer flashes the controllers at the same time after determining that the source addresses of the controllers do not conflict with each other. Finally, the plurality of controllers are flashed at the same time, so that the flashing efficiency is improved, and the flashing consistency of the controllers is ensured.

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...
