Abstract: Disclosed is an electrohydraulic brake system for use in vehicles which can be braked by means of generator operation of an electric drive motor. The brake system comprises, inter alia, a brake booster and an electronic control unit which is provided for distributing the braking effect between a generative component or recuperation braking component and a friction braking component. In order to optimize the take-up of pressure medium, in particular during recuperation braking, the brake booster (6, 11, 15) is configured to be electrically actuated by the electronic control unit (10). The boosting force generated by the brake booster (6, 11, 15) is exerted as a function of variables relevant to the brake system.

Abstract: A method for detecting a malfunction of a brake system may include measuring a deceleration/acceleration upon braking and determining whether the brake system has the malfunction by comparing the measured deceleration/acceleration and a required deceleration/acceleration. If it is determined that the brake system has the malfunction, the method further includes determining whether a braking interval is an interval where braking is performed only through regenerative braking. If so, the method determines that a regenerative brake system has the malfunction. If not, the method further includes determining whether a left friction brake system or a right friction brake system has the malfunction by measuring a yaw rate value and determining whether a front wheel friction brake system or a rear-wheel friction brake system has the malfunction by using a variation amount of a measurement value of the deceleration/acceleration.

Abstract: When a brake ECU is started up rapidly by a brake pedal operation, the brake ECU executes a depression force fluid pressure mode. When the control pressure detected by a control pressure sensor becomes smaller than a switching determination threshold value, the brake ECU determines that an operation of returning a brake pedal is being performed, and switches the braking mode from the depression force fluid pressure mode to a normal control mode. Accordingly, even when the operation of a stroke simulator has been started, no uncomfortable feeling is given to a driver. Further, even when the operation of returning the brake pedal is not being performed, the braking mode is switched from the depression force fluid pressure mode to a simulator non-operation control fluid pressure mode when a vehicle starts to travel. Consequently, desired braking force can be rapidly generated.

Abstract translation: 当通过制动踏板操作快速起动制动ECU时，制动ECU执行抑制力流体压力模式。 当由控制压力传感器检测到的控制压力变得小于切换判定阈值时，制动ECU判断为正在执行返回制动踏板的动作，并且将制动模式从抑制力流体压力模式切换到正常 控制模式。 因此，即使在开始了行程模拟器的动作的情况下，也不会给驾驶员带来不舒服的感觉。 此外，即使当没有执行返回制动踏板的操作时，当车辆开始行驶时，制动模式从踏力流体压力模式切换到模拟器非操作控制流体压力模式。 因此，可以快速产生期望的制动力。
