摘 要：CCP is a calibration protocol based on CAN bus.It has many general-purpose features,such as high communication speed and excellent compatibility.This article introduces its basic principle,communication mode,and work mode for ECU calibration,and discusses a design method of Automobile ECU Calibration based on this protocol.The practical application results show that this calibration system can be implemented effectively on ECU of automobile system for on-line calibration,and provide custom-made function aimed at different demand of users.Therefore,it will be applied well in the automotive electronic control system.
