Abstract

The invention discloses a vehicle controller flashing system and method and related equipment, and the system comprises: an ECU information processing module which is used for analyzing configuration information of a target ECU according to a configuration file of the target ECU, wherein the configuration information comprises the address and the size of the target ECU data storage area; the flash file processing module that is used for analyzing the to-be-flashed file according to the address and the size of the ECU data storage area and generating a binary bin file of the target ECU; the instruction identification module that is used for analyzing a flashing instruction set of the target ECU according to the communication protocol of the target ECU and the flashing instruction configuration file; the message generation module that is used for packaging configuration information of a target ECU, a bin file of the target ECU and the flashing instruction set into message data, wherein the message data is used for flashing the target ECU. The system supports flashing of controllers of various communication protocols, flashing of controllers of various different types and various CAN hardware devices, and is high in applicability and high in controller flashing efficiency.

Description

technical field [0001] The present application relates to the technical field of vehicles, in particular to a vehicle controller flashing system, method and related equipment. Background technique [0002] The electronic control unit (ECU, Electronic Control Unit) is also called the driving computer. The ECU can control the intake air volume, fuel injection volume and ignition time of the engine, so as to indirectly determine the engine operating efficiency, power and torque. [0003] By reflashing the ECU, you can change the parameters that the ECU controls the engine to indirectly determine the engine operating efficiency, power and torque, so as to improve the power performance of the vehicle and reduce the fuel consumption of the vehicle. [0004] However, in the prior art, the controller flashing system used when flashing the ECU is developed based on specific controllers, Controller Area Network (CAN, Controller Area Network) equipment, and communication protocols. Wh...
