Abstract
A method is shown for determining an operating temperature of a continuously variable hydraulic shock absorber and compensating a control signal therefore. A solenoid 62 provides continuous variability in the damping level a shock absorber produces. The solenoid includes a coil 70 which may be used to determine the temperature of the hydraulic fluid in the shock absorber. An electronic controller 68 uses the temperature to compensate a desired damping signal to account for temperature variations. This allows the shock absorber to provide consistent damping levels for the vehicle throughout a broad temperature range, thereby improving the noise, vibration and harshness characteristics of the vehicle.
