Abstract

PURPOSE: To make a braking device which automatically applies brake when a forward vehicle approaches to the own vehicle, small by a method wherein the control valve mechanism of a brake booster is automatically operated directly by the output signal of an automatic sensing system.
CONSTITUTION: An automatic sensing and calculating means A, which senses the distance and relative speed between the forward vehicle and own vehicle and emits output signal 10, 12 or 14 in proportion to the magnitude of possibility of collision, is provided. In addition, the booster 16, which transmits a master brake pedal effort, being magnified, to a master cylinder 18 and at the same time provides the passage to feed back a part of the reaction from the master cylinder 18 to a brake pedal, is provided. Furthermore, an automatic braking means, which operates the differential pressure between before and after the working piston of the booster 16 by means of a system other than the system of the brake pedal in accordance with the output signal issued from the calculating means A, is provided. Stillmore, the control valve mechanism, which is actuated by both the brake pedal and the automatic braking means and controls the differential pressure between before and after the working piston, is provided.
