The invention relates to a method for controlling a hydraulic brake system (10) during a regenerative braking process utilizing a generator braking torque generated by an electric machine (50). In themethod, the hydraulic fluid is displaced in the direction of the wheel brakes (28) by means of a brake cylinder (16), and at least a volume fraction of the hydraulic fluid is conducted into an accumulator (42). The method comprises the step of conveying at least a volume fraction of the hydraulic fluid from the accumulator (42) in the direction of the wheel brake (28) by means of the pump (38) ifthe braking torque demand is above the braking torque limit of the electric machine (50) in order to achieve an increase in the hydraulic braking torque generated by the wheel brake (28). The invention also discloses the hydraulic brake system, a computer program product, a control unit 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,该再生制动过程利用电动机器(50)产生的发电机制动力矩。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,并且使至少一定体积分数的液压流体传导到蓄积器(42)中。该方法包括以下步骤:如果制动力矩需求高于电动机器(50)的制动力矩极限,通过泵(38)将至少一定体积分数的液压流体从蓄积器(42)朝车轮制动器(28)的方向输送,以实现车轮制动器(28)产生的液压制动力矩的增大。本发明还公开了一种液压制动系统、计算机程序产品、控制单元和机动车辆。
