Abstract:
A braking force controller for a vehicle with wheels, comprising:a generator which applies an electrical braking force to one of said wheels,hydraulic actuators which respectively apply braking force to all of said wheels,a fluid pressure control circuit which provides a first fluid pressure,a brake control circuit which provides a second pressure based on the first pressure to said actuators,an antilock brake control circuit which provides a third pressure which is lower than the second fluid pressure to an actuator corresponding to a slipping wheel, anda microprocessor programmed to:control said fluid pressure control circuit to decrease the first fluid pressure when said generator is applying the electrical braking force to said one of said wheels,control said generator to stop application of said electrical braking force to said one of said wheels and control said fluid pressure control circuit to increase the first fluid pressure, when said antilock brake control circuit is providing the third fluid pressure to said actuator corresponding to the slipping wheel,control said brake control circuit to increase the second fluid pressure more gradually than the increase of the first fluid pressure by said fluid pressure control circuit, when said motor generator has stopped application of said electrical braking force to said one of said wheels.
