Vacuum booster brake system with redundancy

The invention relates to a hydraulic brake system, comprising a vacuum brake booster (2), an ESC system having a hydraulic pump (9) for generating a brake force in a wheel-specific manner in a plurality of wheel brakes (10a-d), an ESC control device (20, 30) for actuating the hydraulic pump (9), 40), and a hydraulic pressure sensor (16) for determining a hydraulic pressure in the hydraulic brake system (1). For an electrified vehicle, an electric vacuum pump (3) is provided for supplying the vacuum brake booster (2), the ESC control device (20, 40) being designed to logically and electrically control the electric vacuum pump (3). 本发明涉及一种液压制动系统，该液压制动系统具有：真空制动助力器(2)、具有用于在多个车轮制动器(10a-d)中以车轮专有的方式生成制动力的液压泵(9)的ESC系统、用于操控该液压泵(9)的ESC控制装置(20，40)、以及用于确定该液压制动系统(1)中的液压压力的液压压力传感器(16)。对于电气化车辆，提供有电动真空泵(3)来对该真空制动助力器(2)进行供应，其中，该ESC控制装置(20，40)被设计成以逻辑方式和电气方式操控该电动真空泵(3)。
