    摘要： A system for determining the height of the center of gravity of a vehicle includes an arrangement configured to determine a difference between wheel contact forces, an arrangement configured to determine a transverse acceleration, an arrangement configured to determine comparison values which compares the change in the difference between wheel contact forces with the change in the transverse acceleration, and an arrangement configured to evaluate a roll model which determines the height of the center of gravity from the comparison values. Furthermore, a corresponding method is for determining the height of the center of gravity of a vehicle.

    摘要： A method and a system for operating a brake system of a motor vehicle having traction control are described. The brake system contains sensors which are assigned to the individual vehicle wheels and with which a quantity representing at least the driving and/or braking forces acting between the road surface and the vehicle wheel is detected for the respective vehicle wheel. For operation of the brake system having traction control, pressure quantities which describe the brake pressure established for the respective vehicle wheel are analyzed. The pressure quantities are determined as a function of the quantities detected by the sensors.

    摘要： A vehicle traction control system having capabilities for braking intervention and coefficient of friction detection is provided, a slipping wheel being braked by braking intervention if a slip threshold is exceeded. In order to improve the lateral stability of the vehicle when cornering on road surfaces having a low coefficient of friction, the slip threshold for the drive wheel on the outside of the curve is reduced independently of that of the drive wheel on the inside of the curve and is set to a lower value than that for the wheel on the inside of the curve.

    摘要： The present invention relates to a method and device for driving a brake system pump motor, which has the advantage of simultaneously allowing prioritized, individual braking strategies, using the present invention as a subsystem for intelligently driving the pump motor. The invention provides the additional advantage of reducing pump motor current requirements, allowing the use of a reduced size of pump motor. The invention provides for a predetermined period of full-on voltage at the initiation of a braking request, subsequent periods of variable pump motor voltage on-time, depending on pulse width modulation of a drive motor signal based on a comparison between the motor voltage and a threshold voltage, and subsequent periods of full-on voltage for a predetermined period based on a comparison between the motor voltage and a safety threshold voltage. The invention also provides for minimum on-time per clock cycle for safe braking operations.

    摘要： A method and an apparatus for an anti-spin regulation (ASR) for a vehicle are described. The method is characterized in that a slipping driven wheel (20, 30) is braked by braking means (220, 230). A further driven wheel (20, 30) is monitored by monitoring means, (25, 35). The further driven wheel (20, 30) is braked by braking means (220, 230) in case a slipping trend is determined by determination means (90) for said further driven wheel (20, 30). The apparatus is in particular eligible for use with the inventive method and is characterized in that braking means (220, 230) are implemented for braking a slipping driven wheel (20, 30). Monitoring means (25, 35) are implemented for monitoring a further driven wheel (20, 30). Braking means (220, 230) are implemented for braking the further driven wheel (20, 30) in case a slipping trend is determined by further implemented determination means (90) for said further driven wheel (20, 30).
