Abstract

A vehicle control apparatus is mounted on a vehicle including an emergency stop function to detect an abnormal state of a driver and automatically stop the vehicle. The vehicle control apparatus provides control at a time of stopping the vehicle and includes process execution sections and a process stop section. The process execution sections perform predetermined emergency processes in response to the emergency stop function stopping the vehicle; the emergency processes control instruments mounted on the vehicle and use a battery of the vehicle as a driving power source. The process stop section stepwise stops at least part of the emergency processes performed by the process execution sections based on a predetermined stop sequence.
