Title:
SENSING STEERING AXIS INCLINATION AND CAMBER WITH AN ACCELEROMETER
Document Type and Number:
WIPO Patent Application WO2004090468
Kind Code:
A3
Abstract:
Methods and devices for measuring and calculating wheel alignment angles. Light weight and mechanically robust accelerometers in measurement heads are attached to a vehicle's wheels during an alignment procedure. The output of the accelerometers may be compensated for effects of temperature or thermal hysteresis by memory lookup or a temperature based feedback control loop.
