  • Process for determining a safety margin for a traveling motor vehicle
    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.
