  • Method for indicating a faulty strut and vehicle using same
    Patent number: 7418331
    Abstract: Operating a vehicle with a faulty strut can cause serious consequences. The present disclosure includes a method of detecting a fault within a strut during operation of a vehicle. Pressure within the strut is sensed, and a magnitude of asymmetry within a plurality of the sensed pressures is determined. A faulty strut (e.g. overcharged or collapsed) is indicated when the magnitude of asymmetry is outside of a predetermined range of asymmetry.
