Improvement of Vehicle Vibration while Driving Using Motor Integral CTBA

抄録

With driving parts including a motor equipped inside each wheel, in-wheel motor system drives wheels directly. If the motor is combined with CTBA, the drive system and the suspension system are modularized in a simple structure, expanding inside space and improving cost competitiveness. Moreover, as a controller of driving power and braking force of the motor, it also enhances ride quality and handling by controlling the pitch and yaw of the vehicle. However, in-wheel system directly related to the sash is disadvantageous to vibration isolation of the motor/reduction gear. The purpose of this research is to identify the causes of 1st. order vibration in vehicles with motor integral CTBA and suggest countermeasures to this problem.
