  • Patent number: 12032098
    Abstract: An accuracy of detection of a road surface or the like is improved even in a state where a peak power of reflected light is low. A sensor control device is configured to be mounted in a vehicle capable of acquiring a current location and configured to control a LiDAR-having a light source which emits light to a predetermined region and a light receiving element which receives reflected light of the emitted light, and the sensor control device includes an adjustment unit which acquires map information and adjusts a light receiving level of a light receiving signal of the light receiving element. The adjustment unit determines, based on the map information, a region for which the light receiving level with respect to the light receiving signal is to be adjusted.
