BRAKING FORCE CONTROL METHOD FOR VEHICLE
First Claim
1. A braking force control method for a vehicle that is applied to a vehicle in which regenerative braking force and friction braking force are applied to front wheels that are steered wheels;
- calculates a target braking force of the front wheels; and
controls the regenerative braking force and friction braking force on the basis of said target braking force, wherein comprising steps of;
when at least one of the braking slip quantities of the front wheels exceeds a reference value in a situation where regenerative braking force is applied to the front wheels, with the instance being a reference time point, controlling the friction braking force of the front wheels so as to increase while controlling the regenerative braking force so as to be a provisional target regenerative braking force that is lower by a prescribed value than the regenerative braking force of the front wheels at said reference time point; and
initiating the control for decreasing the regenerative braking force of the front wheels and the control for increasing the friction braking force of the front wheels at the time point when a prescribed period of time has passed from said reference time point so that the regenerative braking force gradually decreases and the friction braking force gradually increases.

Abstract
A braking force control method that is applied to a vehicle in which regenerative braking force and friction braking force are applied to the front wheels. When the braking slip quantity of one of the front wheels that is supplied with regenerative braking force exceeds a reference value, with the instance being a reference time point, the friction braking force of the front wheels is controlled so as to increase while the regenerative braking force being controlled so as to be a provisional target regenerative braking force that is lower by a prescribed value than the regenerative braking force of the front wheels at the reference time point. When a decision is made that a prescribed period of time has passed since the reference time point, the regenerative braking force is gradually decreased and the friction braking force is gradually increased.
