Using the air pressure brake booster and that kind of booster which have addition hydraulic boost, method in order braking boost to do

摘要

The air pressure - hydraulic hybrid type air pressure brake booster is improved. The addition hydraulic boost which is offered by the hydraulic circuit (19 and 20), the saturation point in while operating of the air pressure circuit (Psat) exceeding, it is offered. You can insert in consideration the instability which it occurs with the hysteresis of the air pressure part of the booster (50). (A) shortage of operation of the air pressure circuit which uses the hydraulic circuit is compensated you can do selection for the sake of. With a certain example, as for this revision, through the microprocessor which assigns the revision processing signal it is offered. If this signal is used, deviation of pressure inside the air pressure system neutralizes.
