A spoiler device includes a movable spoiler for a vehicle, the movable spoiler being movable between a retracted position and a deployed position, a link mechanism supporting the movable spoiler, a torsion bar connected to the link mechanism, and an actuation portion rotating the torsion bar.

Spoiler device

A pinch detection apparatus for an opening-and-closing member actuated by a motor, the pinch detection apparatus includes a reference data storage portion calculating load data on the basis of a rotation speed of the motor and an environmental temperature, the reference data storage portion storing the load data and the environmental temperature as reference load data and reference temperature data, respectively, a drive load calculation portion calculating drive load data, and a pinch determination portion configured to determine an occurrence of pinch on the basis of a comparison result obtained by comparing a difference between the reference load data and the drive load data with a threshold, the pinch determination portion configured to correct a relative relation between the difference between the reference load data and the drive load data, and the threshold on the basis of a relative relation between a reference temperature and a drive temperature.

A motor control device includes an acceleration portion for increasing a target number of rotations of a motor every predetermined calculation cycle until the target number of rotations of the motor reaches an upper limit number of rotations, which is set on the basis of a reached position of a driven object from a reference position, the driven object is driven by the motor so that a position of the driven object is changed, a deceleration portion for decreasing the target number of rotations of the motor every calculation cycle after the target number of rotations reaches the upper limit number of rotations, and a main control portion for controlling a drive of the motor on the basis of the target number of rotations.

Motor control device and seat control device for vehicle

A vehicle sunroof apparatus includes: a pair of first and second opening and closing drive units arranged in a widthwise direction, the pair of first and second opening and closing drive units each including: a rail extending in a fore-and-aft direction of a vehicle; a movable body provided so as to be movable on the rail; and a coupling mechanism configured to couple the movable body to a movable panel provided in a roof opening portion, and arranged at widthwise both end portions of the roof opening portion so as to be capable of opening and closing the movable panel; and a control device configured to control operations of the opening and closing drive units.
