Abstract
The present invention is directed to a system for determining lift-off or wheel departure of one or more wheels associated with a vehicle from a road. The system includes a sensor that measures the wheel speed of at least one wheel, and a controller that calculates the resonance frequency of the at least one wheel, calculates variations in the resonance frequency, compares the variations with a threshold, and indicates lift-off of the wheel from the road if the variations exceed a threshold.
Claims14
A method of determining wheel departure from a road comprising:
- measuring the wheel speed of at least one wheel;
- calculating the resonance frequency of the at least one wheel;
- calculating variations in the resonance frequency;
- comparing the variations with a threshold;
- and
- indicating lift-off of the wheel from the road if the variations exceed a threshold.
