Smooth engine start control strategy for P2 HEV

摘要

For P2 configuration HEV, a smooth engine start process is very important under low SOC condition. This paper first established a simulation model in MATLAB/Simulink, and developed two control strategies for smooth start situation, one only considered the coordinative torque control among engine, motor and the main clutch, while the other involved the clutch control in DCT. By means of simulation, two strategies were compared. As the results showed, it is effective to decrease the vibration during the engine start process by slipping the clutch in DCT.
