To increase the accuracy of detecting a road surface, for example, even when the peak of the power of reflected light is low.SOLUTION: A sensor controller 2 is set in a vehicle C of which current position can be acquired, and controls a lidar 1 having a light source 11 for irradiating a predetermined region with light and a light receiving element 17 for receiving reflected light of the irradiated light. The sensor controller has an adjusting unit 22 for acquiring map information 21a and adjusting the light reception level of a light receiving signal of the light receiving element 17. Further, the adjusting unit 22 defines a region where the light reception level for the light receiving signal is adjusted on the basis of the map information 21a.SELECTED DRAWING: Figure 3 【課題】反射光のピークパワーが低くなる状況でも道路面等の検出精度を高める。【解決手段】センサ制御装置２は、現在位置を取得可能な車両Ｃに設置され、所定の領域へ光を照射する光源１１及び照射した光の反射光を受光する受光素子１７を有するライダ１を制御するセンサ制御装置２であって、地図情報２１ａを取得し、受光素子１７の受光信号の受光レベルを調整する調整部２２を備えている。そして、調整部２２は、地図情報２１ａに基づいて、受光信号に対する受光レベルを調整する領域を定めている。【選択図】図３
