Automobile ABS ECU on-line calibration system and method based on CCP protocol

The invention provides an online calibration system for an automobile ABS ECU based on a CCP protocol. The system comprises an upper computer and a lower computer which are interconnected with each other. The upper computer comprises a data storage module, a data analysis module, a control parameter optimization module, a control parameter calibration module and an upper computer command processor CCP; the lower computer is the automobile ABS ECU and comprises an algorithm module and a data communication module. The invention also provides an online calibration method for the automobile ABS ECU based on the CCP protocol. In the method, the CCP protocol is introduced into design of the calibration system of the automobile ABS ECU, which realizes online optimization and modification of control parameters of an ABS; and the control parameters are monitored in a real-time manner by a real-time message processing mechanism of the CCP protocol, which overcomes the problems of hard parameter modification, long development period and poor operability in the existing development methods.
