ASSIST APPARATUS FOR ASSISTING USER TO GET OUT OF VEHICLE

When an attention-required object (an approaching object) is present within a peripheral area of a vehicle in a case where a user's door opening request operation has been detected, a control ECU of an assist apparatus performs a door opening operation restriction process to hold/keep a sliding door at a fully closed position without performing a door opening operation process for the sliding door. When the user's door opening request operation is detected after this door opening operation restriction process has been performed a predetermined number of times, the control ECU performs the door opening operation process to move the sliding door to the fully opened position even when the attention-required object is present.
