20140188317 | ANTI-NOSE DOWN TORQUE CONTROL SYSTEM AND METHOD FOR VEHICLE - An anti-nose down torque control system and method for a vehicle is provided that prevents a nose down phenomenon where, during braking of a vehicle, front parts of the vehicle rotates forward. The method includes braking, by a controller, the vehicle being driven by a motor and applying the anti-nose down torque in a forward direction to the motor in response to a deceleration and a vehicle speed in a last braking stage. In addition, the controller is configured to decrease a braking deceleration and reduce a nose down phenomenon by the anti-nose down torque. | 07-03-2014 |
