The invention relates to a brake system having a master cylinder driven by an electric motor and a wheel-side pressure sensor. A brake system includes a reservoir and a motor-driven master cylinder for actuating a plurality of wheel brakes. The secondary power transfer unit provides pressurized hydraulic fluid at the first PTU output and the second PTU output for actuating the wheel brakes in at least one of a normal non-fail braking mode and a standby braking mode. The secondary power transmission unit includes a PTU motor and at least two pump pistons. At least two brake pressure sensors are provided. Each brake pressure sensor is positioned directly adjacent a corresponding wheel brake for sensing hydraulic pressure at the corresponding wheel brake and responsively generating a brake pressure signal. An electronic control unit is provided for controlling at least one of the secondary power transmission unit and the master cylinder in response to at least one brake pressure signal. The secondary power transfer unit is directly fluidly connected to the reservoir.
本发明涉及具有电动机驱动的主缸和车轮侧压力传感器的制动系统。一种制动系统包括储存器和用于致动多个车轮制动器的电动机驱动的主缸。副动力传输单元在第一PTU输出端和第二PTU输出端提供加压液压流体,用于在正常的非故障制动模式和备用制动模式中的至少一种模式下致动车轮制动器。副动力传输单元包括PTU电动机和至少两个泵活塞。设置有至少两个制动压力传感器。每个制动压力传感器直接邻近对应的车轮制动器定位,用于感测对应的车轮制动器处的液压压力并响应性地产生制动压力信号。设置有电子控制单元,用于响应于至少一个制动压力信号来控制副动力传输单元和主缸中的至少一个。副动力传输单元直接流体连接到储存器。
