Zusammenfassung:To provide a self-diagnostic device capable of detecting performance deterioration of a radar device and attracting passenger's attention.SOLUTION: A self-diagnostic device 11 comprises: a display device 92 which displays a state of a vehicle 1; a radar device 43 which radiates a radio wave to the circumference of the vehicle 1 and detects a reflected radio wave reflected by a target; a detection state determination part 203 which determines, based upon a reflected wave from a road surface behind the vehicle 1, whether the detection state of the radar device 43 is normal when the vehicle 1 is to start, travels forward by a predetermined distance after starting, and stops; and a display control part 204 which lets the display device 92 display the detection state determined by the detection state determination part 203.SELECTED DRAWING: Figure 2 【課題】レーダ装置の性能劣化を検知し、乗員に注意を促すことができる自己診断装置を提供すること。【解決手段】自己診断装置11は、車両1の状態を表示する表示装置92と、車両1の周辺に電波を放射すると共に、電波が物標によって反射された反射波を検出するレーダ装置43と、車両1の発進前、車両1が発進してから所定距離以上前進したとき、及び車両1が停車したときに、車両1の後方の路面からの反射波に基づいて、レーダ装置43の検出状態が正常であるか否かを判定する検出状態判定部203と、検出状態判定部203によって判定された検出状態を表示装置92に表示させる表示制御部204と、を備える。【選択図】図2
