The invention relates to a brake system (34) of a motor vehicle (2) and a method for controlling the brake system. The brake system comprises a service brake system (38) having friction brakes (40a, 40b, 42a, 42b) which can be actuated by a pressure medium, a continuous brake system (44) which is designed as a hydrodynamic or electric retarder, at least one electric machine (24) which is drivingly connected to the wheels (6a, 6b) on the axle (4) and which can be operated at least as a generator, and a foot brake valve (48) which can be actuated by means of a brake pedal (46), the foot brake valve (48) has a brake value transmitter (50) and a brake pedal actuator (52) for generating a restoring force acting on the brake pedal (46), and wherein all the components of the brake system (23) can be controlled by means of an electronic control unit (36), a braking force request informed by means of a deflection signal of the brake pedal (46) is satisfied in a priority order of the electric machine (24), the decelerator (44) and the service brake system (38) which are in generator operation, and wherein the distribution of the braking force to the components of the brake system (23) is informed in a suitable manner to the driver of the motor vehicle (2). In order to inform the driver of information about the distribution of the braking force without the driver having to move the line of sight from the traffic space in front of the driver, it is provided that when at least one change in the distribution of the braking force to the components (24, 38, 44) of the braking system (23) occurs, the braking force is transmitted to the components (24, 38, 44) of the braking system (23). A haptically perceptible signal force (S1, S2, S3, S4) is briefly superimposed on a restoring force acting on the brake pedal (46) by means of the brake pedal actuator (52).
本发明涉及机动车(2)的制动设施(34)和用于控制该制动设施的方法,制动设施具有带能由压力介质操纵的摩擦制动器(40a、40b、42a、42b)的行车制动设施(38)、构造为液力或电动减速器的连续制动设施(44)、至少一个与车轴(4)上的车轮(6a、6b)处于传动连接的至少能作为发电机运行的电机(24)、以及能借助制动踏板(46)操纵的脚制动阀(48),其中,脚制动阀(48)具有制动值发送器(50)和用于产生作用于制动踏板(46)上的复位力的制动踏板促动器(52),并且其中,制动设施(23)的所提到的部件都能借助电子控制器(36)控制,其中,借助制动踏板(46)的偏转发信号告知的制动力请求按优先级地以处于发电机运行中的电机(24)、减速器(44)和行车制动设施(38)的顺序被满足,并且其中,制动力到制动设施(23)的部件的分配情况以适当方式被告知机动车(2)的驾驶员。为了向驾驶员告知有关制动力的分配的信息,而驾驶员为此不必将视线从其前方的交通空间移开,设置的是,在制动力到制动设施(23)的部件(24、38、44)上的分配发生至少一次变化时,借助制动踏板促动器(52)给作用于制动踏板(46)上的复位力短暂叠加了能触觉上感知到的信号力(S1、S2、S3、S4)。
