Abstract
A driving force control unit for a vehicle, which allows transmission of driving force from a driving motor to driving wheels irrespective of releasing an accelerator pedal at a certain or lower vehicle speed when a transmission is set in a driving range, and which switches the magnitude of the driving force while the accelerator pedal is released at vehicle speed no more than the certain vehicle speed between a greater condition and a smaller condition in accordance with depression of the brake pedal so that the driving force is made lower at a depression of the brake pedal than at a release of the brake pedal. In the driving force control unit, the driving force value in said greater condition upon switching from said smaller condition to said greater condition, at a release of the brake pedal during the time the vehicle stops, is increased or decreased according to an inclination angle of the vehicle at the time of stopping. Meanwhile, the increasing rate of said driving force upon switching from said smaller condition to said greater condition, at a release of the brake pedal during the time the vehicle stops, is increased or decreased based on a vehicle inclination angle when …
