SYSTEM AND METHOD FOR MEASURING KINEMATIC PARAMETERS OF A TYRE DURING THE RUNNING OF A VEHICLE |
摘要 |
System and method for measuring the velocity of a point on the surface of the wheel (1) of a vehicle, comprising a source (10; 10A) mounted on the vehicle and capable of sending a signal at a first frequency (f1) to a portion of the moving surface of the wheel (1), a receiver (10; 10B) mounted on the said vehicle in a position such that it can receive at least a fraction of the signal reflected from the said surface portion of the wheel, and at least one processing unit (15), for calculating, from the frequency difference (f2-f1) between the transmitted and the received signals, a quantity representative of the velocity of the portion of wheel with respect to the velocity of the vehicle. The source (10; 10A) and the receiver (10; 10B) are made in the form of ultrasonic transducers, which send the signal to a transverse groove portion of the tread pattern (4) which extends radially, and receive the reflected signal from this portion.
