A pneumatic pressure control method for a vehicle seat includes: repeatedly detecting an internal pressure of a bladder provided inside the vehicle seat at intervals; correcting the internal pressure of the bladder based on a differential pressure between a detection value and a target value; and lengthening a detection interval to detect the internal pressure depending on a time elapsing from starting of the vehicle.

A vehicle seat device includes: a plurality of air bags configured to be provided inside a seat; a flow path having a shared section to communicate with each of the air bags; a plurality of intake valves each of which is arranged at a flow path position at an upstream of each of the air bags when air is pumped into each of the air bags; a plurality of exhaust valves arranged at flow path positions communicating with the shared section; and a control device configured to control operations of the intake valves and the exhaust valves, in which the control device adjusts a discharge speed of internal air by selectively opening the exhaust valves when the internal air of each of the air bags is discharged.

An air pressure control device of a vehicle seat includes: a bulging shape forming unit configured to form a bulging shape on a seat surface by expanding air bags configured to be provided inside a seat; a bulging shape moving unit configured to move a position of the bulging shape formed on the seat surface by each corresponding air bag by sequentially expanding and contracting a plurality of air bags aligned in a direction along the seat surface in an arrangement direction of the air bags; and a pumping capacity adjusting unit configured to increase a pumping capacity of an air pump that pumps air into each air bag as a protrusion amount of the corresponding bulging shape increases when a formation position of the bulging shape is moved.

A vehicle opening and closing body control device includes an opening and closing drive device and a controller. When the opening and closing body is being closed, in a case where the position of the opening and closing body when a trapping of a foreign object is detected is outside a specified range between a fully closed position and a specified position, the controller controls the operation of the opening and closing drive device to reverse the opening and closing body to perform the opening operation by a predetermined opening-and-returning distance and then stop the opening and closing body. In a case where the position of trapping is in the specified range, the controller reverses the opening and closing body to perform the opening operation by the predetermined opening-and-returning distance or a greater distance and then stop the opening and closing body outside the specified range.

A vehicle-door opening/closing control device includes a controller, which controls the operation of a drive device. The controller is configured to supply drive power based on a voltage of an in-vehicle power supply to an electromagnetic clutch. The controller is also configured such that, when stopping an opening/closing body at an intermediate position, the controller supplies the drive power based on the voltage of the in-vehicle power supply to the electromagnetic clutch to put the clutch in the engaged state, and then stops the supply of drive power to the electromagnetic clutch so that the clutch is in the disengaged state after a predetermined holding time has elapsed since the controller has stopped the opening/closing body at the intermediate position. The predetermined holding time differs between a case where the trapping of the foreign object is detected and a case where the opening/closing manipulation is detected.

An electric grill shutter control device includes: a control portion that performs an energization of a motor that drives a movable member that configures the electric grill shutter; a detection portion that detects a rotational speed of the motor; a determination portion that determines whether locking of the movable member is occurred based on whether the energization is performed and the rotational speed; and an identification portion that obtains a rotation amount of the motor in a period around the locking from the rotational speed in a case where the locking occurs and identifying a cause of the locking according to the rotation amount and the energization.

An open/close actuating mechanism control device for a vehicle includes: an actuating mechanism () that is exposed to outside air and that opens or closes on the basis of whether a predetermined condition is satisfied; an open/close failure determining unit () that determines whether an open/close failure of the actuating mechanism (), in which the actuating mechanism () fails to open or close, has occurred; an outside air temperature detecting unit () that detects an outside air temperature; and a determination timing changing unit () that changes timing, at which the open/close failure determining unit () determines that the open/close failure of the actuating mechanism () has occurred, on the basis of the outside air temperature detected by the outside air temperature detecting unit ().
