A sensor system mounted on a vehicle includes: a first sensor configured to acquire information on a first area outside the vehicle; a second sensor configured to acquire information on a second area that partially overlaps with the first area outside the vehicle; and a controller configured to change an information acquisition rate of the first sensor and an information acquisition rate of the second sensor, in which when the information acquisition rate of one of the first sensor and the second sensor falls below a predetermined value, the controller increases the information acquisition rate of the other sensor to be higher than the predetermined value.
