Abstract:
A driving force control unit for a vehicle, said unit operative to:allow 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 selected to a running range; and switch the magnitude of the driving force, while the accelerator pedal is in a released state at a vehicle speed no more than the certain vehicle speed, between a greater condition and a smaller condition in accordance with depression of a brake pedal so that the driving force is made lower for a depression of the brake pedal than for a release of the brake pedal, wherein: at a predetermined or lower vehicle speed, a driving force value in said greater condition is changed according to the vehicle speed; the change of the driving force value in said greater condition is such that that the driving force value becomes smaller as the vehicle speed changes from a speed corresponding to the maximum driving force value to said predetermined vehicle speed; and further switching of said driving force, before stopping the vehicle, from said greater condition to said smaller condition is permitted only in the vicinity of said predetermined vehicle speed.
