Vehicle travel control system

A vehicle travel control system installed on a vehicle and comprising:

• a recognition sensor configured to recognize a situation around the vehicle;
• a sensor cleaning device configured to clean the recognition sensor;
• 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;
• and
• a map database,
• wherein:
• a recognized road shape is a road shape that is in a recognition area around the vehicle and recognized by the recognition sensor;
• a registered road shape is another road shape that is in the recognition area and registered in the map database;
• a cleaning permission condition is that degree of coincidence between the recognized road shape and the registered road shape is equal to or higher than a threshold;
• and
• the control device is further configured to:
• permit execution of the sensor cleaning processing when the cleaning permission condition is satisfied;
• and
• prohibit the execution of the sensor cleaning processing when the cleaning permission condition is not satisfied.
