Patent ID: 7284803

Claim:
A vehicle brake control apparatus incorporated in a vehicle brake apparatus applied for vehicles having a motor for driving at least front wheels as a power source, the vehicle brake apparatus including: master fluid pressure generating means for generating a master fluid pressure corresponding to the operation of a brake operating member by a driver; pressuring means for generating a fluid pressure higher than the master fluid pressure; pressure adjusting means for adjusting the magnitude of pressuring the master fluid pressure using the fluid pressure by the pressuring means; and regenerative brake power controlling means for controlling the regenerative brake power generated by the motor, the vehicle brake control apparatus comprising: regenerative and cooperative brake controlling means for adjusting compensation brake power corresponding to the operation of the brake operating member so that characteristics of total brake power relative to the operation of the brake operating member are matched with target characteristics set in advance, the total brake power being the sum of the master fluid pressure brake power, which is fluid pressure brake power based on the master fluid pressure generated by the master fluid pressure generating means, and the compensation brake power composed of the regenerative brake power by the regenerative brake power controlling means and/or pressuring fluid pressure brake power, which is the fluid pressure brake power based on the pressuring magnitude by the pressure adjusting means; and front/rear brake power proportion controlling means for controlling front/rear brake power proportioning which prohibits an increase in brake power applied to rear wheels when the rear wheels are liable to be locked ahead of the front wheels during the operation of the brake operating member by the driver, wherein the vehicle brake control apparatus further comprises additional brake power generating means for increasing brake power applied to the front wheels by increasing at least the regenerative brake power applied to the front wheels which is controlled so as to adjust the compensation brake power by the regenerative and cooperative brake controlling means when the operation of the brake operating member demands the braking power larger than that at the start of the front/rear brake power proportion controlling during the controlling the front/rear brake power proportion.
