The process for evaluation the acceleration of a vehicle wheel uses an accelerometer with three sensing axes. These are not aligned with the axes of measurement, but rather allow calculation of the required values by combination of components. The procedur...

An air spring leveller leakage detector compares measured heights (h1, h2) and pressures (p1, p2) at times (t1, t2) corresponding to start of sleep mode or threshold (hsu) crossing or set time separation (Dt) to detect leaks by pressure and height criteria...

Improvements for a vehicle stabilizer bar assembly having a pair of stabilizer bar members (40a,40b) that are selectively uncoupled via a clutch assembly (60) to provide a vehicle with improved traction. A first improvement concerns a reserve powering appa...

The invention relates to an on-vehicle breakdown-warning report system (11) in which an occurrence of break-down is detected and judged based on a signal in an electronic control system installed on a control apparatus for an engine ignition system, a char...
