Automobile controller program flashing method, device and system and terminal

Abstract

The invention discloses an automobile controller program flashing method, device and system and a terminal. The system comprises a terminal and a hardware flashing tool, wherein the terminal is used for acquiring a communication protocol corresponding to the hardware flashing tool, communicating with the hardware flashing tool according to the communication protocol, receiving the basic information of the automobile controller group, which is sent by the hardware flashing tool, from the automobile controller group, and acquiring a program file corresponding to the controller in the automobile controller group; the hardware flashing tool is used for receiving the basic information of the automobile controller group, sending the basic information to the terminal, receiving the program file returned by the terminal according to the basic information, and flashing the program file to the corresponding controller in the automobile controller group. The system, disclosed by the embodiment, brings convenience for a user to flash or update the automobile controller program, shortens the time spent in flashing all the controllers of the automobile, improves the program flashing efficiency, and further improves the whole automobile production efficiency.

Description

technical field [0001] The present invention relates to the technical field of automobiles, in particular to a method, device, system and terminal for program flashing of an automobile controller. Background technique [0002] Based on the factors of environment, energy and technological development, new energy vehicles are the current and future trend of automobile development, among which pure electric vehicles are the mainstream products. [0003] In order to adapt to the needs of the times and customers, there are more and more controllers (that is, ECU (Electronic Control Unit) electronic control units) on new energy vehicles. In the process of producing or using vehicles, it is usually necessary to Flash the program or update the program. Each ECU has different functions, and its built-in applications are also different, so it is necessary to flash different applications for each ECU. [0004] The process of the CAN bus controller flashing control method based on UDS...

AI Technical Summary

Problems solved by technology

[0005] However, due to the large number of controllers in the car, and the different flashing tools and flashing methods developed by suppliers are only applicable to their respective controllers, for example, the hardware flashing tool supported by the controller is A, if the hardware flashing When tool A is not available, the user cannot complete the program flashing or updating of the controller through other hardware flashing tools, which causes great troubles for the OEMs and easily causes confusion of the flashing tools. Inconvenient to use and low work efficiency
