Abstract

Provided is a device for improving riding comfort of an in-wheel motor driving electric vehicle. The device for improving riding comfort of an in-wheel motor driving electric vehicle according to an embodiment of the present invention includes a suspension device which reduces the vertical movement of the body of an electric vehicle that has an in-wheel motor for each wheel, wherein the driving force or the breaking force of the wheels, which is generated by the friction between the surface of the ground and the wheels which rotate by the torque of the in-wheel motors, is applied to the vehicle body as the component force that disturbs the vertical movement of the vehicle body at the angle between a virtual link of the suspension device and the surface of the ground, thereby altering the weight on springs of the suspension device, such that the springs expand or retract.
