Abstract:
A motor torque control method for a motor-driven vehicle is carried out when a vehicle reduces its speed to a low speed or is in a stopped state, gear backlash and torsion of a drivetrain are minimized, and thus impact on the drivetrain which may occur during starting or restarting of a vehicle is minimized. The motor control method includes determining whether vehicle speed is in a speed reducing state less than a set vehicle speed or in a stopped state; determining a required torque command, an anti-jerk torque, and an additional drivetrain arrangement torque for removing drivetrain backlash based on vehicle operation state information when the speed reducing state or the stopped state is determined; and determining a motor torque command by using the required torque command, the anti-jerk torque, and the drivetrain arrangement torque.
