METHOD AND DEVICE FOR DETECTING A LOOSENED WHEEL BOLT ON A WHEEL

A method for detecting a loosened bolted wheel joint on a wheel of a vehicle. The angular velocity of a hub of the wheel is evaluated. A periodic wheel modulation of the angular velocity is ascertained. An oscillation of the wheel generated due to the loosened bolted wheel joint is detected, using a...

Beschreibung
Zusammenfassung:	A method for detecting a loosened bolted wheel joint on a wheel of a vehicle. The angular velocity of a hub of the wheel is evaluated. A periodic wheel modulation of the angular velocity is ascertained. An oscillation of the wheel generated due to the loosened bolted wheel joint is detected, using a step-change in a phase angle of the modulation by an expected angular increment, which is a function of the number of bolts.
