Classification: CPC B  E | IPC B  E

Claim 6:
7. A power door device comprising:
a motor actuator configured to open/close a door of a host vehicle;
an information acquisition unit configured to acquire information about each of vertical acceleration, namely acceleration of the host vehicle in a vertical direction, a motor load for the motor actuator, and a degree of door opening, namely a degree of opening of the door;
a setting unit configured to use information about how the degree of door opening corresponds to a door opening/closing speed to extract the door opening/closing speed corresponding to the current degree of door opening and set the extracted door opening/closing speed as a target door opening/closing speed;
a control unit configured to control driving of the motor actuator so that the target door opening/closing speed set by the setting unit is obtained at the current degree of door opening; and
a diagnostic unit configured to make a first determination as to whether or not the motor load exceeds a predetermined load threshold and a second determination as to whether or not the vertical acceleration exceeds a predetermined acceleration threshold, and diagnose, based on results of the first and second determinations, whether or not an overload condition has occurred at the door, wherein
when the motor load exceeds the load threshold as a result of the first determination, the diagnostic unit diagnoses an abnormality where the overload condition has occurred at the door, and
when the vertical acceleration exceeds the acceleration threshold as a result of the second determination, the diagnosis of the abnormality is deferred.
