ABSTRACT:
The method for reducing motor shock of a parallel hybrid electric vehicle equipped with a continuously variable transmission calculates an upper limit of acceleration and an upper limit of jerk of the vehicle based on vehicle speed; calculates a maximum motor torque and a maximum motor torque change rate based on the calculated upper limit of the acceleration and upper limit of the jerk; and generates a motor torque command such that a motor torque is less than the calculated maximum motor torque and a motor torque change rate is less than the calculated maximum motor torque change rate.
