A method for controlling a hydraulic brake system 10 during a regenerative braking process where a displacement of a hydraulic fluid in the direction of a wheel brake 28 is performed by means of a brake cylinder 16 and at least one volume fraction of the hydraulic fluid is conducted via a pressure dissipation valve 34, which is situated in an open position, into an accumulator. In the method, furthermore, the pressure dissipation valve 34 is adjusted in the direction of a closed state, in order to realize an increase of a hydraulic braking torque effected by the wheel brake 28, if an overall braking torque which is made up of the hydraulic braking torque and a generator braking torque effected by an electric machine 50 is lower than a braking torque demand, and if the generator braking torque lies below a braking torque limit of the electric machine 50. The invention further relates to a hydraulic brake system (10) for a motor vehicle, a computer program product, a control unit (48), and a motor vehicle.
本发明涉及一种用于在再生制动过程期间控制液压制动系统(10)的方法。在该方法中,通过制动缸(16)来使液压流体朝车轮制动器(28)的方向移位,并且使液压流体中的至少一个体积分数的液压流体经由位于打开位置的压力消散阀(34)传导到蓄积器中。此外,在该方法中,如果由车轮制动器(28)产生的液压制动力矩和电机(50)产生的发电机制动力矩构成的总制动力矩小于制动力矩需求,并且如果该发电机制动力矩低于电机(50)的制动力矩极限,则将该压力消散阀(34)朝关闭状态的方向调整,以实现该液压制动力矩的增大。本发明还包括一种用于机动车辆的液压制动系统(10)、一种计算机程序产品、一种控制单元(48)、以及一种机动车辆。
