Abstract
The disclosure provides a cleaning device and a method for an external sensor. The external sensor is disposed on a moving body and configured to detect an outside of the moving body. The cleaning device includes: a cleaning part that sprays cleaning fluid on a detection surface of the external sensor for cleaning; and a sensor performance calculation part that calculates a performance detection value of the external sensor. The cleaning part sprays the cleaning fluid based on the calculated performance detection value. The cleaning part sprays the cleaning fluid based on a calculated change amount of the performance detection value with respect to time or a travel distance of the moving body.
