Abstract

The invention provides an automobile ECU (Electronic Control Unit) flash device. The automobile ECU flash device comprises a power supply module, a PC (Personal Computer) interface module, an ARM9 module electrically connected with the PC interface module, an M3 module electrically connected with the ARM9 module, a communication protocol module electrically connected with the M3 module, and a flash interface module electrically connected with the communication protocol module, wherein the PC interface module, the ARM9 module, the M3 module, the communication protocol module and the flash interface module are in electrical connection with the power supply module. According to the automobile ECU flash device provided by the invention, based on use of the PC interface module, the ARM9 module and the M3 module, an ECU firmware can be changed, so that an automobile can be suitable for the emission regulations of different countries by updating the ECU firmware, and BUG repair and reduction of emission output can be realized by upgrading the ECU firmware, simultaneously, with the communication protocol module integrated with multiple communication protocols, the automobile ECU flash device can be used for different automobiles, and the application range is wide..

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile ECU flashing device. Background technique [0002] The automotive engine control unit (ECU) indirectly controls fuel injection, ignition and vehicle emissions. The software that runs on the ECU is called "firmware" because it is harder to change than normal software. ECU can be used in many different cars by changing its firmware. In fact, a type of car can adapt to different countries' emissions regulations by updating its firmware. After the car leaves the factory, upgrading the firmware can also fix bugs and reduce emissions output. [0003] In recent years, ECU reprogramming technology has developed rapidly, and it will maintain this momentum in the future. [0004] In the automotive service industry, by reprogramming the ECU, system operating parameters can be changed and calibrated, bugs can be repaired and emissions can be reduced. However, various r...
