METHOD AND DEVICE FOR DETERMINING A FORCE EXERCISED BY THE GROUND ON A WHEEL

摘要

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.
