Anti-nose down torque control system and method for vehicle

摘要

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.

1. An anti-nose down torque control method for a vehicle, comprising:
braking, by a controller, the vehicle being driven by a motor; applying, by the controller, 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; and decreasing, by the controller, a braking deceleration and reducing a nose down phenomenon by the anti-nose down torque, wherein the applying of the anti-nose down torque to the motor includes;
applying, by the controller, the anti-nose down torque a the moter;calculating, by the controller, a maximum value of the anti-nose down torque from a braking deceleration-torque map;determining, by the controller, the anti-nose down torque using a motor rotating speed-torque map that indicates the calculated maximum value of the anti-nose down torque and a torque zero point versus a motor rotating speed; andapplying, by the controller, the determined anti-nose down torque to the motor.
