Method and device for determining a force exercised by the ground on a wheel
First Claim
1. A method for determining a longitudinal force (Fx) exerted on a wheel of a motor vehicle by a ground surface supporting the wheel, the vehicle comprising connection means which connect the wheel to a body of the vehicle, the method comprising:
- measuring an actual force (FAX) at a level of at least one measurement point in the connection means,calculating a force (FDx, Fx) resulting from a transmission via the connection means from the at least one measurement point to the wheel, of a body-associated force (FADX, FAX), which depends at least on the actual force,calculating the longitudinal force (Fx) exerted on the wheel by the ground surface as a function at least of the force (FDx;
Fx) resulting from the transmission of the body-associated force.

Abstract
A device and method are provided for determining a longitudinal force (Fx) exerted on a wheel of a motor vehicle by a ground surface supporting the wheel, the vehicle including connections means which connect the wheel to a body of the vehicle. An actual force (FAX) is measured at the level of at least one measurement point in the connection means. A force (FDx, Fx) is calculated which results from a transmission via the connection means from the at least one measurement point to the wheel, of a body-associated force (FADX, FAX), which depends at least on the actual force. The longitudinal force (Fx) exerted on the wheel by the ground surface is calculated as a function at least of the force (FDx; Fx) resulting from the transmission of the body-associated force.
