HYDRAULIC BRAKING ASSISTANCE DEVICE

摘要

In order to solve the efficiency problems of a braking assistance device, the invention comprises making the same in the form of a hydraulic control. In this case, a master cylinder (7-10) of a braking circuit (3-4) is provided with a pressure chamber upstream from the braking circuit. The pressure chamber is then subjected to an injection (28) of hydraulic liquid by a pump (34). The pump is controlled (39) based on the braking needs. The control includes mobile equipment (54) sensitive to said needs and controlling an injection valve (29-30).
