Abstract
A brake force control apparatus having a hydraulic brake unit for generating a hydraulic brake force and a regenerative brake unit for generating a regenerative brake force is provided which can prevent a driver from having an unnatural feeling due to a discontinuous change in the hydraulic brake force. A brake controller controls the hydraulic brake unit so that at least a predetermined fluid pressure is always supplied to a wheel cylinder while a brake operation is performed.
Claims8
A brake force control apparatus comprising:
- a hydraulic brake unit for generating a hydraulic brake force;
- a regenerative brake unit for generating a regenerative brake force;
- and
- a brake controller for controlling said hydraulic brake unit so that at least a predetermined positive fluid pressure is always supplied to a wheel cylinder while a brake operation is performed.

A brake force control apparatus, comprising:
- first braking means for generating a frictional braking force on a wheel of a vehicle by pressing a brake pad against a disk rotor of the vehicle wheel;
- second braking means for generating a regenerative braking force on the wheel;
- and
- a brake controller for controlling the first braking means and the second braking means so that not only a regenerative braking force but also a predetermined frictional braking force is always exerted on the wheel during a brake operation of a vehicle operator in a condition that a required braking force is less than a maximum regenerative braking force of the second braking means.
