Title:
SYSTEM AND METHOD FOR MEASURING THE GRIP PERFORMANCE OF A VEHICLE
Document Type and Number:
WIPO Patent Application WO/1995/027192
Kind Code:
A1
Abstract:
A system and a method are disclosed for measuring the grip performance of a vehicle (10) through relation to a lumped-sum parameter derived from force and displacement measurements taken from selected elements forming the suspension (30) of the vehicle. For at least one wheel (20, 24) of the vehicle, the magnitude and relative direction of the instantaneous load force vector acting on each support member (48a, b, 54a, b, etc.) thereof are measured. The load force vectors are resolved with respect to a relative plane into a first load force component, a second load force component, and a third load force component normal to said first and second components. The load force components are then related to a common reference plane to derive normalized load force components, which normalized components are then summed to derive normalized first, second and third load force components which correspond to the instantaneous grip force developed between the wheel of the vehicle and the ground surface.
