<p>A system for automatic cleaning of exterior surfaces of light lenses and other exterior signalling or viewing surfaces of a motor vehicle (10) comprises at least one cleaning nozzle (12A) having a fluid inlet connectable to a source (14) of pressurised cleaning fluid and a fluid outlet for directing a pressurised cleaning fluid toward an exterior surface (12) to be cleaned, an automatically operating cleaning control device (21) for repetitive on-off control of supply of pressurised cleaning fluid to the cleaning nozzle (12A), and a vehicle movement sensor device (20) connected to the cleaning control device (21) and responsive to movement of the vehicle to enable the cleaning control device (21) only in response to the vehicle movement sensor device (20) sensing travel of the motor vehicle. The vehicle movement sensor device (20) may include a vehicle vibration sensor (20A) and means (20B) for detecting vehicle vibrations indicative of travel of the motor vehicle.</p> |
