Abstract
Abstract An electronic brake pedal adjustment apparatus has an apparatus for setting braking characteristics by which the driver can enter the relationship between the desired brake fluid pressure with respect to a given brake pedal effort, a detector for detecting an actual brake pedal pressure; and a computer for calculating a desired brake fluid pressure based on the set braking characteristics for the detected brake pedal effort. A brake fluid pressure control device is also provided so as to make the actual brake fluid pressure commensurate with the calculated brake fluid pressure. The relationship between the desired brake fluid pressure and the given brake pedal effort is shown on a display.
