Method of diagnosing fault in motor vehicle clutch involves producing clutch actuator position signal for comparison to estimated signal

摘要

The method for diagnosing a fault in a motor vehicle clutch involves producing a clutch actuator position signal using the value of the adjustment applied to the clutch input (10). The value is applied to a modelling circuit input (20) to produce an output signal (21) for the position reached by the actuator. The measured and estimated values are compared (3) to produce a calculated output value.
