  • Publication number: 20150360666
    Abstract: An electromechanical brake booster is provided for a braking system of a vehicle, having a valve body and an input rod, the valve body, to which at a displacement motion in a brake application direction has been imparted, being displaceable up to a differential travel equal to a limit differential travel with reference to the input rod, and then a co-displacement motion in the brake application direction being impartable to the input rod if the co-displacement motion is acted against at most by a retention force below a predefined threshold value, and at least one buffer element being disposed on the input rod and/or on the valve body in such a way that if a retention force above the predefined threshold value acts against the co-displacement motion, the differential travel is increasable above the limit differential travel by way of a deformation of the at least one buffer element.

  • Patent number: 8315765
    Abstract: In a method for reducing the rollover risk in vehicles, at least one state variable which characterizes the transverse dynamics of the vehicle is ascertained and is used as the basis for an intervention into the steering system and the braking system which stabilizes the vehicle. A multivariable control is carried out in which two control loops are superimposed, the first control loop being based on control of the yaw rate and the second control loop being based on control of the transverse acceleration. The steering system as well as the braking system may be adjusted via the first and second control loops.

    Abstract: Described is a device for stabilizing a vehicle in critical driving situations, including a vehicle dynamics control system having a control unit, including a vehicle dynamics control algorithm, and at least one actuator and an additional vehicle stability system having an associated actuator. Vehicle dynamics control may be executed in a particularly simple and trouble-free manner when the vehicle dynamics control algorithm is retrofitted with a distribution function which derives an actuating request for an actuator of the vehicle dynamics control system as well as an actuating request for at least one actuator of the vehicle stability system from a controller output variable.

  • Publication number: 20060025896
    Abstract: A device is described for stabilizing a vehicle in critical driving situations, including a vehicle dynamics control system having a control unit, in which a vehicle dynamics controller is stored, at least one final control element, and a sensor system for measuring different driving condition variables, and including a rear-wheel steering system having a control unit and a final control element. The electronic stability program may be integrated into a control unit if the electronic stability program algorithm includes a distributor unit which, from a regulator output variable, generates both a setpoint requirement for the final control element of the vehicle dynamics control system and also a setpoint requirement for the final control element of the rear-wheel steering system.

  • Publication number: 20050256622
    Abstract: A method and a device for influencing the handling characteristics of a vehicle, by increasing the vehicle stability and hence increasing the driving comfort for the driver of the vehicle. This is done by activating at least two systems in the vehicle, which improve the handling characteristics and thus the vehicle stability. The activation of a system occurs in a specified sequence as a function of the activation and/or of the effect of the preceding systems on the handling characteristics achieved by the activation. The sequence provided for this purpose is the initial activation of a chassis system, followed by a steering system and finally by a brake system.

  • Patent number: 6749270
    Abstract: Device and method for controlling at least one operating-dynamics variable of a vehicle in closed loop. The device includes a braking system which contains a reservoir for accommodating a braking medium, and at least one brake circuit. The brake circuit includes first valve arrangements on the output side and a second valve arrangement on the incoming side. Wheel brake cylinders allocated to the brake circuit are connected to the first valve arrangements. The reservoir is connected to the second valve arrangement. The device includes a system with which the wheel brake cylinder exhibiting the greatest brake pressure is ascertained for the at least one brake circuit. If a driver-independent brake actuation exists, then the brake pressure of the wheel brake cylinder exhibiting the greatest brake pressure is adjusted by appropriate driving of the second valve arrangement.
