The invention relates to a brake system having an electric motor-driven master cylinder and a low-pressure accumulator. The brake system includes a motor-driven master cylinder for generating brake actuation pressures at first and second master cylinder outputs to hydraulically actuate pairs of wheel brakes. The secondary brake module is configured to selectively provide pressurized hydraulic fluid at the first and second power transfer unit outputs for actuating the first and second pairs of wheel brakes. A low pressure accumulator is hydraulically disposed between the first and second pairs of wheel brakes. The low pressure accumulator is in indirect fluid communication with the reservoir via the first and second master cylinder outputs and the master cylinder. The low pressure accumulator at least partially provides slip control to the wheel brakes in coordination with the secondary brake module when the brake system is in a normal non-fail braking mode.
本发明涉及具有电动机驱动的主缸和低压蓄能器的制动系统。制动系统包括电动机驱动的主缸,用于在第一和第二主缸输出端处产生制动致动压力,以液压致动成对的车轮制动器。副制动模块配置成在第一和第二动力传输单元输出端处选择性地提供加压的液压流体,用于致动第一和第二对车轮制动器。低压蓄能器液压地置于第一和第二对车轮制动器之间。低压蓄能器经由第一和第二主缸输出端以及主缸与储存器间接流体连通。当制动系统处于正常的非故障制动模式时,低压蓄能器与副制动模块协调地至少部分地向车轮制动器提供打滑控制。
