Patent attributes
A vehicle travel control system installed on a vehicle includes: a recognition sensor configured to recognize a situation around the vehicle; a sensor cleaning device configured to clean the recognition sensor; and a control device configured to execute vehicle travel control based on result of recognition by the recognition sensor, and to actuate the sensor cleaning device to execute sensor cleaning processing that cleans the recognition sensor. The control device permits execution of the sensor cleaning processing in a situation where decrease in recognition performance has a small influence on the vehicle travel control. For example, when a surrounding vehicle recognized by a first recognition sensor is also recognized by a second recognition sensor, the control device permits execution of the sensor cleaning processing that cleans the first recognition sensor.
