Abstract
Sensor cleaning system for cleaning sensors, in particular vehicle sensors, and associated method, characterized by a liquid reservoir for holding a cleaning liquid, and including a control unit for activating a switch unit and including at least one nozzle for spraying at least one sensor, the switch unit being provided between the liquid reservoir and the at least one nozzle, a liquid line being provided between the liquid reservoir and the switch unit and at least one nozzle line being provided between the switch unit and the at least one nozzle.
Claims12
Sensor cleaning system for cleaning sensors, comprising a liquid reservoir for holding a cleaning liquid, comprising a control unit for activating a switch unit and comprising at least one nozzle for spraying at least one sensor, the switch unit being provided between the liquid reservoir and the at least one nozzle,
- a liquid line being provided between the liquid reservoir and the switch unit and at least one nozzle line being provided between the switch unit and the at least one nozzle, characterized in that a gas reservoir fluidically connected to the liquid reservoir is provided for holding a cleaning gas,
- in that a gas line is provided between the gas reservoir and the switch unit,
- in that the cleaning liquid and the cleaning gas are pressurized during operation such that the cleaning liquid and/or the cleaning gas can be delivered toward the particular nozzle, and
- in that the switch unit is designed such that the at least one sensor can be cleaned via the at least one nozzle line by means of the cleaning liquid leaving the at least one nozzle and/or by means of the cleaning gas leaving the at least one nozzle.
Method for cleaning sensors by spraying a sensor, characterized by the following method steps:
- a. providing pressurized cleaning liquid in a liquid reservoir;
- b. providing compressed cleaning gas in a gas reservoir;
- and at least one of the following:
- c1. alternately spraying the sensor with the cleaning liquid and the cleaning gas;
- and
- c2. pulsatingly spraying the sensors with the cleaning liquid and/or the cleaning gas.
