Patent ID: 8639438

Claim:
A method for assisting a driver in the driving of a vehicle during a braking test of said vehicle on a test track to evaluate performance characteristics of one or more tires on said vehicle, wherein the test track comprises an acceleration portion and a test portion, and wherein the test portion is divided into a plurality of adjacent strips (Z 1 , . . . , Zn) mainly extending lengthwise in the track, the width (Iz) of each strip being greater than or equal to the width of the tires of the vehicle, such that each strip is worn by tires of the vehicle during each braking of the vehicle on said strip, such that the wear of each strip affects the assessment of tire performance characteristics, said assistance method comprising: selecting at least one strip out of the plurality of strips of the track, according to the known or determined wear of that strip; determining a theoretical trajectory of the vehicle, such that, by following said theoretical trajectory, the vehicle can be braked on the selected strip indicating the theoretical trajectory to be followed to the driver of the vehicle; and braking the vehicle and measuring performance characteristics of the tires on said vehicle.
