Wireless upgrade of body controller and burning system using the body controller

Abstract

The invention discloses a wireless upgraded automobile body controller. The wireless upgraded automobile body controller comprises a BCM automobile body controller, wherein the BCM automobile body controller is provided with a wireless communication module, a local area network control module and an MCU. The invention further discloses a programming system adopting the wireless upgraded automobile body controller. The programming system adopting the wireless upgraded automobile body controller comprises the wireless upgraded automobile body controller and program storing equipment used for storing the programs to be upgraded, wherein the program storing equipment is connected with the wireless upgraded automobile body controller through wireless signals or networks, and the wireless upgraded automobile body controller is connected with a control system of automotive electronics through a communication line. The invention further discloses a programming method of the programming system. The wireless upgraded automobile body controller and the programming system adopting the wireless upgraded automobile body controller have the advantages that a wireless short-distance download function and a wireless remote download function of a program can be achieved, long-distance business trips for programming a small number of automotive electronic control system programs are avoided, product cost is reduced, a client can use products conveniently, and a large amount of labor is not needed any more for disassembling and assembling of an outer shell.

Description

technical field [0001] The present invention relates to the field of automotive electronics, in particular to a wireless upgrade vehicle body controller, a programming system using the wireless upgrade vehicle body controller, and a programming method using the wireless upgrade vehicle body controller programming system. Background technique [0002] At present, the main implementation methods of software upgrade of automotive electronic control system are as follows: [0003] Method 1: First download the software to be upgraded to the program burner through the PC, then connect the program burner to the burner tool, then put the PCB board of the automotive electronic control system into the burner tool and align it with the download interface. Finally power on the programming software. [0004] Method 2: Connect the PC, MCU program download data cable and the PCB board of the automotive electronic control system in series, and directly download the program to the MCU by op...

AI Technical Summary

Problems solved by technology

[0007] ①. There are many devices involved, and the installation and connection are complicated, so it is not suitable for software upgrade and programming of small batch products during development and maintenance;

[0008] ②. The shell of the automotive electronic control system needs to be disassembled. During the disassembly process, there are risks of damaging the shell and improper assembly, and it is labor-intensive. If the automotive electronic control system installed on the vehicle needs software upgrades, the disassembly work will be more difficult;

[0009] ③. When the automotive electronic control system on the vehicle is difficult to disassemble or the programming personnel are not on-site in an emergency, various problems such as traffic problems and personal safety problems will be caused;

[0010] ④. It may be necessary for car companies to arrange long-distance business trips for technicians due to a small amount of product software upgrades, which will bring a great economic burden to the company
