Abstract
An abnormality detection device includes a sensor configured to detect an external environment of a vehicle and an electronic control unit configured to: detect a traveling state of the vehicle; acquire a control command value for the vehicle in automatic driving control, the vehicle being caused to travel automatically in the automatic driving control; determine, based on a difference between the traveling state and the control command value, whether the traveling state is abnormal; determine, based on a detection result from the sensor, whether the external environment is suitable for execution of the automatic driving control; and determine that an abnormality has occurred in an automatic driving system when it is determined that the traveling state is abnormal and it is determined that the external environment is suitable for the execution of the automatic driving control, the automatic driving system performing the automatic driving control.
