Automobile ECU recovery system and recovery method

Abstract

The invention provides an automobile ECU recovery system and a recovery method. The system comprises a power supply module, a PC host, a communication protocol module, an OBD plug and an automobile ECU. The PC host is in communication connection with the communication protocol module through a PC port module, the communication protocol module is in communication connection with the automobile ECU through the OBD plug, and the power supply module is electrically connected with the communication protocol module and used for supplying power for the communication protocol module. According to the automobile ECU recovery system and the recovery method, due to the fact that ECU control parameters are written in an ECU memorizer in a file format, automobile configuration is flexible, and customization is convenient. The ECU recovery system is light and simple, and can well meet requirements of engine plants, vehicle finishing plants, 4S stores and the like. Meanwhile, through recovery of the ECU, automobile power can be improved, and oil consumption can be reduced, so that acceleration, starting, power connection and the like of an automobile are remarkably improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile ECU flashing system and flashing method. Background technique [0002] The car computer (ECU) controls the working state of the car engine to make the engine work at its best. Usually, ECU parameter calibration and diagnostic testing are required before the car goes off the assembly line to ensure the normal performance of the engine, especially the parameter configuration of the electronic control system, so that the engine is in the best state. [0003] However, the control data in the car ECU is set according to the engine-related components, so the same engine, but with different components combined with the engine, the ECU control parameters are different. [0004] However, in existing cars, the performance of the ECU is not fully utilized when the car leaves the factory. How to improve the power and reduce fuel consumption by flashing the ECU is an urgent...
