VEHICLE BODY VIBRATION DAMPING CONTROL DEVICE

摘要

In the present invention, a requested drive control torque Tw is computed from an accelerator pedal opening (APO) and a brake pedal force (BPF) at a computation unit (51), and front and rear direction disturbances ?Ff and ?Fr are calculated based upon variation in wheel velocity Vw at a calculation unit (52). An estimation unit (53) estimates vehicle body vibration (pitching vibration ?p and vertical bounce vibration xb) accompanying variation in Tw and vehicle body vibration (?p and xb) accompanying ?Ff and ?Fr. A computation unit (54) obtains a vibration damping-use drive torque correction amount for suppressing each of the estimated vehicle body vibration (?p and xb) accompanying the variation in the Tw and the vehicle body vibration (?p and xb) accompanying the ?Ff and ?Fr, and a calculation unit (56), on the basis of the torque correction amount and a suppression priority degree which has been set at a setting unit (55) which prioritizes suppression of the pitching vibration, obtains a vibration damping-use drive torque correction amount commanded value dTw* for suppressing the vehicle body vibration (?p and xb) while satisfying the priority degree so as to correct the driving control force of the vehicle by only dTw*.
