1. A door opening and closing assisting apparatus that assists an opening and closing operation of a swing door pivotally supported by a hinge mechanism provided on a vehicle, the door opening and closing assisting apparatus comprising:
an acceleration sensor provided on the swing door to detect an opening and closing acceleration of the swing door and a vehicle height acceleration of the swing door which is an acceleration in a vehicle height direction;
a door actuator that performs driving for assisting the opening and closing operation of the swing door; and
an ECU (electronic control unit) configured to function as:
an information obtainer that obtains information on the opening and closing acceleration and the vehicle height acceleration of the swing door;
a determiner that determines magnitudes of the opening and closing acceleration and the vehicle height acceleration of the swing door;
a target assisting power computer that computes a target assisting power for assisting the opening and closing operation of the swing door; and
a controller that performs driving control for the door actuator based on the target assisting power, wherein
the controller starts the driving control for the door actuator at a timing at which the information obtainer obtains the opening and closing acceleration and the vehicle height acceleration of the swing door and at a timing at which the determiner determines the opening and closing acceleration of the swing door is above a predetermined opening and closing acceleration threshold and the vehicle height acceleration of the swing door is below a predetermined vehicle height acceleration threshold.
