Patent ID: 6998974

Claim:
A method for monitoring wheels of a motor vehicle having an antilock brake system for fault states, such that upon occurrence of a fault state, the position of the wheel at which the fault state occurred is indicated, comprising: assigning a wheel unit to each wheel to be monitored, the wheel unit monitoring tire inflation pressures in the wheels for fault states comprising high and low tire pressures, said wheel units transmitting only fault state signals to a central evaluation unit that a fault state has occurred in at least one wheel, evaluating signals supplied by antilock brake system sensors for determining the position of any wheel at which a fault state has occurred by means of output signals from the antilock brake system sensors corresponding to known wheel locations signaling wheel rotational speeds, wherein an under-inflated tire of reduced effective radius has a faster rotational speed comparatively, and an over-inflated tire of increased effective radius has a slower rotational speed comparatively.
