Abstract

The invention relates to an automobile controller software flashing method and system, which comprises a computer, a flashing tool, at least two controller flashing devices and a power supply, wherein the computer is connected with the flashing tool, and software for controlling the flashing tool and a controller software flashing package are stored in the computer; a DB9 serial port of a wire harness assembly of each controller flashing device is connected with a flashing tool, a controller connector of the wire harness assembly of each controller flashing device is connected with each controller to be flashed in a one-to-one correspondence manner, and each controller flashing device is provided with a switch. The power supply is used for supplying power to the controller to be flashed; and the software control flashing tool used for controlling the flashing tool flashes the controller software flashing package stored in the computer to the controller to be flashed. Writing of different types of controllers is supported, and quick response can be achieved by turning on or turning off the switch; flashing of a plurality of controllers of the same type is supported at the same time, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of flashing controller software, in particular to a method and system for flashing software of an automobile controller. Background technique [0002] With the rapid development of the new four modernizations of automobiles, especially the development of intelligent networking, the number of controllers on a car is also increasing. For example, the transmitter needs to have an EMS controller, and the gearbox needs to be controlled by a TCU. Controllers, various switches and door compartment controls of body modules require a body controller BCM; different controllers have different hardware and functions, and the control software they carry also has their own advantages and disadvantages. [0003] In the vehicle research and development stage, the hardware development of a controller is relatively simple, and the relatively mature and platform-based hardware is basically selected. However, in order to realiz...
