Abstract
A control system for cleaning and monitoring a sensor assembly disposed externally on a vehicle is provided and includes a contaminant detection/identification sub-system that measures a resonant frequency of the sensor assembly to detect contaminants disposed on an exposed surface of the sensor assembly. A cleaning sub-system is provided and includes cleaning modes that expel the contaminants from the exposed surface of the sensor assembly. A temperature monitoring device monitors a temperature of an actuator disposed in the sensor assembly and a fault detection device detects faults in the sensor assembly.
