Title:
VEHICLE DRIVING FORCE CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2008089120
Kind Code:
A
Abstract:

To provide a vehicle driving force control device for effectively suppressing the rotating vibration of a driving wheel during accelerating a vehicle by promoting an up-shift change of the gear ratio of a transmission when the driving wheel has or may have rotating vibration during accelerating the vehicle.

During accelerating the vehicle (Step 110), when detecting the rotating vibration of the driving wheel (Step 130) or determining that a travelling road is a cross road (Sep 160), the vehicle driving force control device gradually reduces target driving force Fp_t_future necessary for computing the shift stage of the transmission 16 (Steps 190, 200) until the rotating vibration of the driving wheel is over (Step 210) or cross road travel is finished (Step 220), to promote the up-shift change of the shift stage of the transmission.
