VIBRATION CONTROL APPARATUS OF VEHICLE WITH MOTOR |
摘要 |
A vehicle vibration control apparatus includes a motor for supplying driving torque; left and right drive wheels at the s ends of a drive shaft rotated by driving torque produced by a motor; ABS for controlling braking force applied with the drive wheels; and a control unit for controlling the rotational speed of the motor to follow rotational speed of the drive wheels when the ABS is operated. Thereby, vibration generated between the motor 10 and the drive wheel 22 and 24 can be minimized. |

1. A vibration control apparatus of a vehicle having a motor comprising:
a motor for supplying driving torque; a left drive wheel and a right drive wheel installed at opposite ends of a drive shaft rotated by driving torque produced by the motor; ABS for controlling braking force applied with the drive wheels; and a control unit configured for controlling rotational speed of the motor to follow rotational speed of drive wheels when the ABS is operated and not to control motor speed to follow the drive wheel speed when a rotational acceleration of the motor is less than a predetermined value; the control unit being further configured to calculate an inertial torque of the motor by using the rotational acceleration of the motor and to generate a torque command of the motor in a direction opposite that of the inertial torque. |
