Abstract: An opening and closing body drive mechanism that drives an opening and closing body between an open position and a closed position; a drive unit to drive the opening and closing body; a detecting unit to detect movement of the opening and closing body; and a control unit to control driving of the opening and closing body. The control unit carries out a feedback control to control driving of the opening and closing body such that the movement of the opening and closing body, detected with the detecting unit, matches a predetermined target value when no abnormality occurs in the detecting unit or in wiring connecting the detecting unit and the control unit.

Abstract: A device for opening and closing opening/closing body comprising: an opening/closing body to open/close with respect to an opening of a base body; a closing mechanism; a control portion to control the closing mechanism; and a position detection portion, wherein the closing mechanism includes an engaging portion provided in either one of the base body and the opening/closing body; an engaged portion provided in the other of the base body and the opening/closing body; a closing mechanism drive portion to shift the engaging portion between being an opened state and a closed state; and an interaction detection portion to detect interaction between the engaging portion and the engaged portion; and the control portion carries out zero position setting to set position information to the zero position when the engaging portion shifts to the closed state or to the opened state.

Abstract: An opening/closing body opening/closing device includes: an opening/closing body; a closing mechanism; an opening/driving body driving section; a control section; and a position detection section. The closing mechanism includes an engaging portion, an engaged portion, a closing mechanism-side driving section, and an interaction detection section. The control section causes the closing mechanism-side driving section to perform closing driving and, after the closing driving, sets the engaging part to an open state so as to allow the closing mechanism to lock the opening/closing body through engagement between the engaging portion and the engaged portion when a positional difference between a current position and an engageable position of the opening/closing body is outside a predetermined range.

Abstract: A mobile body moving device comprising: a mobile body; a drive unit that moves the mobile body; a sensor that detects movement of the mobile body; and a control unit that controls driving of the drive unit, wherein in a high-speed region where the mobile body moves at a speed faster than a predetermined speed, the control unit controls driving of the drive unit so that a mobile body actual speed based on a mobile body information from the sensor is adjusted to a speed of the target movement speed rule by comparing the mobile body actual speed and the target movement speed rule, and in a low-speed region where the mobile body moves at a speed less than or equal to the predetermined speed, the control unit drives the drive unit by comparing a predetermined low-speed movement speed rule and the target movement speed rule.

Abstract: An opening and closing body drive device includes: an opening and closing body; a latch mechanism; an opening and closing body drive section; a control section; and a movement sensor, wherein the control section includes a middle reference count value and a pushing count value, and the control section compares the current count value acquired by the movement sensor when the opening and closing body becomes the predetermined state with the latch mechanism and the middle reference count value with each other and corrects the current count value, and the control section assumes that the opening and closing body has arrived the fully-closed position when the opening and closing body has moved by an amount corresponding to the pushing count value from a count value corresponding to the middle reference count value and stops driving of the opening and closing body drive section.

Abstract: An opening/closing body drive mechanism 1 comprises an opening/closing body 2 to move between an open position and a closed position; a drive unit 3 to drive the opening/closing body 2; a detecting unit 4 to detect the movement state of the opening/closing body 2; and a control unit 5 to control driving for the opening/closing body 2 based on an output of the detecting unit 4, wherein the control unit 5 carries out a feedback control to control the driving such that a physical value being detected with the detecting unit 4 is brought to be a target value; and in a case that the information from the detecting unit 4 differs from predetermined information according to the feedback control and a control value given to the drive unit 3 exceeds a predetermined threshold value, determines that information from the detecting unit 4 is abnormal.

Abstract: An opening and closing body control device includes: an opening and closing body; a drive section which includes a motor; a detection section; a control section; and an amplifier which compares a counter electromotive force of the motor with a ground and amplifies the counter electromotive force to power that enables the control section to operate. In the opening and closing body control device, the control section is capable of shifting back and forth between an operation state and a low power consumption state, and when the counter electromotive force is generated by the motor in the low power consumption state, the control section shifts from the low power consumption state to the operation state by amplified power generated through amplification of the counter electromotive force by the amplifier and controls the opening and closing movement of the opening and closing body.
