The vehicle inspection apparatus is for inspecting behavior of at least one control object mounted on a vehicle whose behavior is controlled through behavior control performed by a control section included in a control system mounted on the vehicle in accordance with a behavior request inputted from an external device. The vehicle inspection apparatus includes a behavior judging section to judge whether or not the control object is abnormal on the basis of a detected behavior value of the control object and an estimated behavior value of the control object, whose dimensions have been matched with each other.
