Abstract
A braking system for an automotive vehicle, having a first brake system and a second brake system. The first brake system includes a master cylinder responsive to an operation of an operator-controller brake operating member, for generating a fluid pressure which corresponds to an operation value of the brake operating member, and a first brake actuated by the fluid pressure generated by the master cylinder. The first brake is adapted to produce a braking effect which is smaller than a desired or optimum braking effect corresponding to the operation value of the brake operating member. The second brake system has a second brake and is controlled by a controller such that the second brake produces a braking effect which is equal to a difference between an actual braking effect applied to the vehicle, and the desired braking effect.
