Abstract
A method of controlling a sensor cleaning system includes identifying whether a vehicle is in a driving assistance mode, identifying whether a sensor is contaminated, cleaning the sensor by applying power using a logic set in a cleaning device according to a driving condition of the vehicle in response to the sensor being identified as contaminated, and reidentifying whether the sensor is contaminated.
Claims18
A method of controlling a sensor cleaning system of a vehicle, the method comprising:
- determining, by a driving mode determining unit, that the vehicle is in a driving assistance mode;
- determining, by a sensor, a contamination state of a front portion of the sensor;
- controlling, by a control unit, a cleaning process for the sensor by applying power to a cleaning device according to a logic set according to a driving condition of the vehicle in response to the front portion of the sensor being determined as contaminated, wherein the cleaning device is inclined at a predetermined angle on an upper part of the sensor to spray fluid to the front portion of the sensor;
- and
- re-determining, by the sensor, the contamination state of the front portion of the sensor.
A sensor cleaning system of a vehicle, the sensor cleaning system comprising:
- a driving mode determining unit configured to determine whether the vehicle is in a driving assistance mode;
- a sensor configured to determine whether a front portion of the sensor is contaminated;
- a cleaning device inclined at a predetermined angle on an upper part of the sensor to spray fluid to the front portion of the sensor;
- and
- a control unit configured to control a cleaning process for the sensor by applying power to the cleaning device according to a logic set according to a driving condition of the vehicle in response to the front portion of the sensor being determined as contaminated,
- wherein the sensor is further configured to re-determine whether the front portion of the sensor is contaminated after the cleaning process.
