Body controller, burning system and burning method using the same

Abstract

The invention discloses a vehicle body controller. The vehicle body controller comprises a BCM vehicle body controller, wherein the BCM vehicle body controller is provided with a TD-LTE module, a local area network control module and an MCU. The invention further discloses a burning system utilizing the vehicle body controller. The system comprises the vehicle body controller and a program storage device which is used for storing program need to be updated, wherein the program storage device is connected with the vehicle body controller through a wireless signal or a network, and the vehicle body controller is connected with a vehicle electronic control system through a communication line. The invention further discloses a burning method utilizing the system. According to the technical scheme, an NFC module in wireless communication and the TD-LTE module in the wireless communication are transplanted into the BCM vehicle body controller, and the problems that an existing electronic control system is troublesome to dismantle and easily damaged in a program updating process and a few products go wrong or are recalled due to the program burning updating are ingeniously solved.

Description

technical field [0001] The invention relates to the field of automotive electronics, in particular to a body controller, a burning system using the body controller, and a burning method using the body controller. 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 operating the PC. [0005] Method 3: Connect the CAN diagnostic instrument to the CAN line interface, and perfo...

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
