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.
Claims35
A method one of for detecting cornering of a vehicle and for ascertaining the transverse acceleration of the vehicle, characterized in that a signal indicating one of cornering of the vehicle, a measure of the curve radius, and the transverse acceleration of the vehicle is detected for at least each side of the vehicle, using a reference speed;
- a reference speed 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.
A device for one of detecting cornering of a vehicle and ascertaining the transverse acceleration of the vehicle, characterized in that the device has a curve calculator one of for detecting a signal indicating vehicle cornering, for ascertaining a measure of the curve radius, and for determining the transverse acceleration of the vehicle, as a function of a reference speed of at least each side of the vehicle;
- and in that the device has at least two reference-speed calculators for determining a reference speed 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.
A method for detecting cornering of a vehicle, comprising the steps of:
- detecting a signal indicating one of cornering of the vehicle, a measure of a curve radius and a transverse acceleration of the vehicle for at least each side of the vehicle using a reference speed;
- and
- determining the reference speed of each side of the vehicle as a function of a deceleration of at least one wheel on the side of the vehicle.
A method for ascertaining a transverse acceleration of a vehicle, comprising the steps of:
- detecting a signal indicating one of cornering of the vehicle, a measure of a curve radius and the transverse acceleration of the vehicle for at least each side of the vehicle using a reference speed;
- and
- determining the reference speed of each side of the vehicle as a function of a deceleration of at least one wheel on the side of the vehicle.
A device configured to detect cornering of a vehicle, comprising:
- a curve calculator configured to detect a signal indicative of one of vehicle cornering, a measure of a curve radius and a transverse acceleration of the vehicle as a function of a reference speed of at least each side of the vehicle;
- and
- at least two reference-speed calculators configured to determine the reference speed of at least one side of the vehicle as a function of a deceleration of at least one wheel on the side of the vehicle.
