  • Patent number: 8965655
    Abstract: A method and device for operating a brake-slip regulating arrangement of a vehicle brake system in various operating modes, in accordance with driving conditions, including: activating, in an on-road operating mode, the arrangement on at least one rear axle and one front axle, even in the off-road operating mode, the arrangement continues to operate on at least one rear axle of the vehicle until the brake slip on at least one wheel of a front axle is less than or equal to a specified brake-slip limit; if the specified brake-slip limit is exceeded by the brake slip on the at least one wheel of the front axle, putting the arrangement out of operation on the rear axle and is not put into operation again until the brake slip on the at least one wheel of the front axle is again less than or equal to the specified brake-slip limit.

  • Patent number: 8955923
    Abstract: A brake system for a motor vehicle, in particular for a utility vehicle, with a device for reducing the yawing moment on the front axle of the vehicle, characterized in that a device for measuring the slip and/or a device for measuring the load on the rear axle or on two running wheels of the rear axle of the vehicle arranged on sides opposite one another is present and a regulating or control device for influencing the brake pressure on the front wheels is present which limits the brake pressure on the front wheels depending on the measured slip and/or depending on the measured load on the rear axle or on the running wheels of the rear axle, the regulating or control device multiplying the difference of the brake pressures on the front wheels by a value which is smaller than 1.

  • Publication number: 20150046057
    Abstract: A method and device for the electronic control of the brake force distribution according to a differential slip or differential speed between at least one wheel of the front axle and at least one wheel of the rear axle of a vehicle, in which, when a differential slip threshold value or a differential speed threshold value is exceeded by the differential slip or the differential speed, the brake pressure at the rear axle is limited, characterized in that the differential slip threshold value or the differential speed threshold value is determined according to the braking request.

  • Patent number: 8918262
    Abstract: A pressure control device of a vehicle, including a pressure controller of a fluid pressure brake system for brake slip-dependent control, including a relay valve having a supply port supplied by a supply pressure, a venting port connected to a pressure sink, a control port and at least two working ports, in which a working port is assigned to at least one brake cylinder and the other working port is assigned to at least one brake cylinder of another wheel, in which each working port of the relay valve is connected to a 2/2-way valve controlled by a control unit and assigned to a respective vehicle side and establishes a connection between the relevant working port and the assigned brake cylinder or blocks the connection, depending on control unit actuation, and in which the control port of the relay valve is connectable to a brake control pressure formed in accordance with the braking input, to a supply pressure of a pressure reservoir or to a pressure sink by a valve system formed by one 3/2-way or two 2/2-

  • Patent number: 8870299
    Abstract: A service brake device of a vehicle, including at least one ABS pressure control valve which is controlled for slip-regulated braking by an electronic control unit, has at least one inlet valve and one outlet valve and is arranged upstream of a pressure medium actuated brake cylinder, a pressure medium line which supplies the ABS pressure control valve with pressure medium and into which a pressure controlled by a valve device arranged upstream of the ABS pressure control valve is feedable, wherein the valve device feeds a pressure derived from a reservoir pressure of a pressure medium reservoir into the pressure medium line as a function of an activation by the electronic control unit.

  • Publication number: 20130238209
    Abstract: A pressure-medium-activated brake device of a vehicle without brake pressure control but with brake slip control (ABS) for driver-independent control of the brake slip during a braking process, and traction control (TCS) for driver-independent control of the drive slip during an acceleration process.
