Abstract
A method and device for detecting cornering of a vehicle, or for ascertaining the transverse acceleration (ay) of a vehicle, where a signal indicating cornering of the vehicle, a measure of the curve radius, or the transverse acceleration (ay) of the vehicle is detected, using a reference speed (vS, vSL, vSR) for at least each side of the vehicle; and where a reference speed (vS, vSL, vSR) of one side of the vehicle is determined as a function of the deceleration of at least one wheel on this side of the vehicle.
Claims11
A method for detecting cornering of a vehicle, or for ascertaining the transverse acceleration (ay) of a vehicle, characterized in that a signal indicating cornering of the vehicle, a measure of the curve radius, or the transverse acceleration (ay) of the vehicle is detected for at least each side of the vehicle, using a reference speed (vS, vSL, vSR);
- a reference speed (vS, vSL, vSR) of a side of the vehicle being determined as a function of the deceleration of at least one wheel on this side of the vehicle.
The method as recited in one of the preceding claims, characterized in that the speed of at least two vehicle wheels is ascertained, and the reference speed (vS, vSL, vSR) of each side of the vehicle is ascertained, the reference speed (vS, vSL, vSR) of a wheel being determined as a function of the deceleration of the fastest wheel on the side.
A device for detecting cornering of a vehicle, or for ascertaining the transverse acceleration (ay) of a vehicle, according to a method as recited in one of the preceding claims, characterized in that the device has a curve calculator (12) for detecting a signal indicating vehicle cornering, for ascertaining a measure of the curve radius, or for determining the transverse acceleration (ay) of the vehicle, as a function of a reference speed (vS, vSL, vSR) of at least each side of the vehicle;
- and in that the device has at least two reference-speed calculators (10, 11) for determining a reference speed (vS, vSLvSR) of at least one side of the vehicle, as a function of the deceleration of at least one wheel on this side of the vehicle.
