Abstract

The invention provides an electronic control unit (ECU) calibration method based on a CCP or XCP protocol. The method is characterized by comprising the following steps: calling a diagnostic engineering tool to unlock a target ECU; activating and maintaining CAN communication between a host based on the CCP or the XCP and a target unit by sending a diagnosis message; analyzing a calibration parameter file to obtain information of calibration parameter of the ECU; and acquiring and / or setting the value of the calibration parameter of the target ECU based on the acquired information of the calibration parameter. The invention also relates to an ECU calibration system, and an electronic device and a computer readable medium capable of implementing the calibration method according to the invention. According to the method and the system provided by the invention, under the condition that the safety is ensured, operation is still convenient, and an implementation scheme for integrating decryption, CCP analysis, searching and setting of the target equipment is realized with extremely high integration degree.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to the communication and control of electronic control devices of automobiles. Background technique [0002] With the development of technology, electronic control units (Electronic Control Unit, ECU) are widely used in current automobiles for the control of various components of the vehicle. In order to solve the communication between a large number of electronic control devices in the car and reduce the increasing signal lines, the vehicle adopts the Controller Area Network (CAN) bus to realize the communication and control of the vehicle electronic control system. [0003] To this end, the Automation and Measurement System Standards Association (ASAM) proposed a CAN-based ECU calibration protocol, namely the CCP protocol (CAN Calibration Protocol). [0004] In the current technology, there are many solutions for calibrating the ECU of the vehicle by using the CCP protocol. [0005]...
