Analysis and Research on High Voltage Interlock Fault of a Hybrid Vehicle
Aiming at the problem of high voltage interlock fault of a hybrid vehicle,the control principle is analyzed.It is found that the fault is caused by the fact that the motor controller of the gearbox can not be controlled directly in on-board diagnostics(OBD)mode,so that the motor controller of the gearbox can not communicate with the engine and the engine can not start.Based on the analysis of the fault causes,the hidden trouble in design is found out,and the system design is improved to solve the problem of high voltage interlock.This experience can be used for reference to improve the reliability of high voltage interlock function in the development of new vehicle.
