Calibration system of machine controller and hybrid electric vehicle

Abstract

The embodiment of the invention provides a calibration system of a machine controller and a hybrid electric vehicle. The calibration system comprises a motor controller, a communication unit and a calibration unit, wherein the motor controller is provided with a data port and a controller area network (CAN) interface; the motor controller acquires motor operating parameters through the data port, the motor operating parameters are processed according to a CAN protocol, and the data which are processed according to the CAN protocol are transferred to the CAN interface; the communication unit is connected with the CAN interface, receives the data which are processed according to the CAN protocol and converts the data into the compact camera port (CCP) data; and the calibration unit is provided with a CCP interface and acquires the CCP data through the CCP interface. The embodiment of the invention utilizes a CAN bus which is stable currently as a communication mode, so that the calibration system has strong antijamming capability and is applicable to the electromagnetic environment of the vehicle. The embodiment of the invention further discloses a CCP calibration protocol, so that the calibration system is universalized and has strong portability.
