  • Patent number: 7610983
    Abstract: A method for damage limitation in the event of an offset frontal collision between two motor vehicles, with a first signal which signals an imminent collision triggering the steerable front wheels (9, 10) to turn inward in opposite directions, is to minimize the impact-induced yaw moment. To this end, the steerable wheels are moved back to the initial position again after the collision or if the collision has not taken place at all. To this end, two actuators (17?, 17?) with an external power source are provided in the case of a vehicle which is equipped for this purpose, with each actuator being associated with a steerable wheel (9, 10).
    Type: Grant

  • Patent number: 5357798
    Abstract: A process for determining a safety margin with respect to adhesion between tires and roadway of a travelling motor vehicle comprises, detecting longitudinal and transverse acceleration values (ax, ay), a rotational wheel acceleration value (Phi), and a dynamic steering angle value, and producing signals indicative thereof. A longitudinal adhesion value (Six) is determined as a function of the longitudinal acceleration (ax) and the rotational wheel acceleration (Phi), while a transverse adhesion value (Siy) is determined as a function of the transverse acceleration (ay) and the dynamic steering angle. Maximum attainable longitudinal and transverse acceleration values (axLIM, ayLIM) are next determined by multiplying the longitudinal and transverse acceleration values (Six, Siy) by vehicle specific coefficients (Kx, Ky) and a limit curve (aLIM), e.g., an ellipse, is established.
