  • Publication number: 20030217897
    Abstract: The present invention relates to a friction brake (1, 31, 41, 51), in particular a disc brake, for a motor vehicle with a friction element (3, 33, 43, 53), e.g. a brake disc, coupled to the rotation of a vehicle wheel, forming a friction pairing of the friction brake (1, 31, 41, 51) with at least one associated brake lining (4, 5, 34, 35, 46-49), and with at least one clamping device (6, 26) for pressing at least one brake lining (5, 34, 35, 46-48) to the friction element (3, 33, 43, 53).

  • Patent number: 6618662
    Abstract: A method and a device for anti-slip control, in particular, for traction control, in a motor vehicle, in which, in a first operating mode, a braking force is applied individually to each driving wheel with a tendency to spin to reduces its slip, and in which, in a second operating mode, an output quantity of the driving motor is additionally reduced if two driving wheels on the same axle show a tendency to spin, thereby avoiding, in an especially reliable manner, unwanted switching from the first to the second operating mode. A switch from the first to the second operating mode takes place no earlier than the end of a first waiting time that is selected in proportion to the difference between the braking forces applied to the two driving wheels with a tendency to spin and occurs after the tendency to spin of the second driving wheel is detected.

  • Patent number: 6611747
    Abstract: An exemplary method is described for influencing the moment delivered by a vehicle drive of a vehicle. In this method a change in load which occurs during cornering of the vehicle is detected, upon detection a minimum value of an intervention quantity which influences the torque delivered is determined and the vehicle drive is acted upon by the minimum value of the intervention quantity for a selectable period of time. To achieve an improvement in the change in load performance of a vehicle in cornering and an improvement in the driving performance of the vehicle in coasting operation, the minimum value determined for the intervention quantity and/or the period of time is corrected as a function of the coefficient of friction of the road surface on which the vehicle is traveling and/or as a function of a deceleration of the vehicle.

  • Patent number: 6595601
    Abstract: A method for the open-loop or closed-loop control of the braking action at at least one wheel of a vehicle. In this method, a transverse-dynamics quantity is ascertained which describes the transverse dynamics of the vehicle. As a function of a vehicle-dynamics quantity which describes the vehicle dynamics, or a wheel-dynamics quantity which describes the wheel dynamics of at least one wheel, it is determined whether a driver-independent braking intervention is necessary. In the event that a driver-independent braking intervention is necessary, a pulse-shaped signal is determined for triggering the actuators assigned to at least one wheel. The first pulse of the pulse-shaped signal is influenced in its time duration as a function of the transverse-dynamics quantity.

  • Patent number: 6594558
    Abstract: In a method for checking tires of vehicles during driving, signals which provide information about an adhesion between the tire and the roadway in the vertical direction with respect to the roadway are detected by sensors provided at the tire. The signals are evaluated in an evaluation unit with respect to their amplitude, such that the amplitude characteristic for the detected signals can indicate a disturbance occurring at the tire. An occurrence of a disturbance is indicated on a display unit and is stored for diagnostic purposes.

  • Patent number: 6564138
    Abstract: A method and a device, respectively, for providing traction control of a motor vehicle in which the slip of the driven wheel of the motor vehicle on the inside of the curve is only regulated when its slip exceeds a predefined slip threshold. The predefined slip threshold is weighted with a weighting factor as a function in dependence on the occurring transverse acceleration, and in this connection, the weighting factor is given by an equation as being inversely proportional to the radius of curve of the road.

  • Patent number: 6487489
    Abstract: The invention is directed to a method and an arrangement for controlling the speed of a vehicle. The actual speed of the vehicle is determined and a desired speed and/or limit speed is pregiven. Furthermore, an engine drag torque controller and/or a drive slip controller are provided. The deviation between desired and/or limit and actual speed is supplied to at least one of these controllers. In the active speed control operation, at least one of these controllers influences an output quantity of the drive unit in dependence upon the speed deviation. In the active road speed limit operation, the drive slip controller influences an output quantity of the drive unit in dependence upon the speed deviation.

  • Patent number: 6456924
    Abstract: A method and a device for controlling slippage of a vehicle wheel are proposed. A traction controller, which intervenes in a drive torque of a drive unit of the vehicle in response to incipient slippage at at least one driven wheel, is provided. Moreover, it is ascertained whether the vehicle is located in an exit area of a curve. If this is the case, the traction controller is influenced so that improved traction of the vehicle results as compared to cornering designed for stability. Furthermore, at least one quantity determining the intervention is modified in response to cornering or straight-ahead driving.
