The invention relates to the technical field of automobiles, and discloses an automobile brake boosting system and an automobile brake boosting method based on the automobile brake boosting system. The automobile brake boosting system comprises a vacuum booster, a turbocharger, a vacuumizing device and a brake pedal; an air chamber diaphragm partition plate is arranged in the vacuum booster so asto limit the interior of the vacuum booster into a positive pressure cavity and a negative pressure cavity, a vacuum valve communicated with the positive pressure cavity and the negative pressure cavity is arranged on the air chamber diaphragm partition plate, and an air valve communicated with the positive pressure cavity and a brake boosting push rod used for outputting power are arranged on thevacuum booster. The air outlet end of the turbocharger is connected with the air valve through an air guide pipe, the vacuumizing device is connected with the negative pressure cavity, and the brakeboosting push rod is connected with the brake pedal. The automobile brake boosting system has the beneficial effects that high-pressure air is provided for the vacuum booster through the turbocharger,the reaction time of the vacuum booster in the braking process is shortened, the pedal feeling is improved, and the braking distance is shortened.

    本发明涉及汽车技术领域,公开一种汽车制动助力系统及基于该汽车制动助力系统的汽车制动助力方法,该汽车制动助力系统包括:真空助力器、涡轮增压器、抽真空装置及制动踏板;真空助力器内设有气室膜片隔板,以将真空助力器内限定成正压腔及负压腔,气室膜片隔板上设置有连通正压腔与负压腔的真空阀,真空助力器上设有与正压腔连通的空气阀及用于输出动力的制动助力推杆;涡轮增压器的出气端通过一导气管与空气阀相连,抽真空装置与负压腔相连,制动助力推杆与所述制动踏板相连。本发明的有益效果为:通过涡轮增压器给真空助力器提供高压空气,缩短制动过程中真空助力器的反应时间,提高踏板感和缩短制动距离。
