Abstract
A control method and system for reducing tip-in shock includes fixing a wheel with a wheel brake of a vehicle when an engine of the vehicle starts. A motor position sensor value is detected when a motor connected to the wheel through a plurality of gears is operated forward by a forward torque and a motor position sensor value when the motor is operated backward by a backward torque, by applying the forward torque and the backward torque to the motor with the wheel being fixed. An entire backlash generated between the plurality of gears is calculated on the basis of the motor position sensor values. A driving current for driving the motor is applied to the motor in accordance with the calculated entire backlash.
