This study concerns the design of Electronic Control Units (ECUs) for the Body Control System (BCS) of Pure Electric Vehicle (PEV). The main research contents are divided into two parts: its CANopen application layer protocol and the model based design of fault detection for anti-pinch window. Firstly, the structure of the BCS and the function of each ECU were analyzed. Then according to the communication needs among the ECUs, the CANopen protocol for each ECU was designed. It contained the design of Network Management, Process Data Objects and Service Data Objects. A CANopen network simulation platform was designed by CANoe software and its components CANoe.CANopen. According to the analysis of anti-pinch window model system, the algorithm based on H-/H4 fault detection observer estimation is proposed. Apart from the previous methods, the pinch torque rate is considered as a fault under the pinched condition to generate a residual. A residual is zero in normal, but it will deviate from the constant when sensing the pinched condition. Co-simulation model of CANopen protocol and the anti-pinch model based on CANoe-MATLAB and the bench test are design to verify the designed ECUs. The test results show that the bus load rate is 3.49% and the results of detection time are respectively 0.18 and 0.185s, which show the CANopen protocol and the anti-pinch algorithm are proper to the BCS of PEV.
