| 20080204264 | OCCUPANT DETECTING APPARATUS - An occupant detecting apparatus includes a detecting portion detecting whether an occupant is seated on a seat, and a judging portion judging whether the occupant occupies the seat on the basis of information detected by the detecting portion. The judging portion judges that the seat is unoccupied by the occupant when a state where a detection that the occupant is not seated on the seat by the detecting portion continues for a judgment time after the detecting portion detects that the seat is occupied by the occupant. | 08-28-2008 |
| 20090069985 | Headrest Apparatus for Vehicle - A headrest apparatus for a vehicle includes a headrest rear portion supported at a seatback, a headrest front portion movable between a fully closed position and a fully open position, a driving device for moving the headrest front portion, a capacitance sensor detecting a change in capacitance in association with an approach of the head of an occupant, and a controlling device for controlling the headrest front portion to move to the fully open position in response to information that a vehicle is approaching from the rear, the controlling device controlling the driving device to stop a movement of the headrest front portion when the head of the occupant is detected on the basis of a detection signal from the capacitance sensor, the controlling device including a first filter having a first cutoff frequency and a second filter having a second cutoff frequency lower than the first cutoff frequency. | 03-12-2009 |
| 20090243353 | SEAT APPARATUS - A seat apparatus includes a seat adapted to be arranged on a floor of a vehicle, a motor driving the seat to move, and a control unit supplying electric power to the motor by controlling a duty ratio with duty cycle control. The control unit determines an initial start-up time in which the duty ratio is defined as a first duty ratio over a period between the time the motor is started up after being powered by the control unit and the time before the seat driven by the motor starts moving. The control unit reduces the duty ratio when the initial start-up time elapses and sets the duty ratio to a second duty ratio smaller than the first duty ratio when the seat starts moving. | 10-01-2009 |
| 20090284062 | SEAT DRIVING APPARATUS - A seat driving apparatus includes: a gear transmission mechanism, preventing a backlash by means of the wedge member applied with a biasing force of a biasing member and transmitting a torque; an actuator, operating a seatback of a seat; and a control unit, controlling driving of the actuator. The control unit includes a seat operation mode in which the actuator is driven to operate the seatback at a predetermined speed and a creep mode in which the actuator is driven at a slower speed than a speed in the seat operation mode. The actuator is driven in the creep mode until a load for releasing the holding of the gear transmission mechanism is applied to the wedge member and subsequently the actuator is driven in the seat operation mode when the seatback is operated in an opposite direction from the previous operational direction thereof. | 11-19-2009 |
| 20100001871 | COMMUNICATION ANOMALY DETECTING DEVICE, AND PASSENGER DETECTING DEVICE - An information request portion receives an information request signal transmitted to an information response portion at its own receiving port. The information request portion comprises at least either a power supply system anomaly determination portion or a ground anomaly determination portion. The power supply system anomaly determination portion determines a short-circuit between a signal line and a power supply system in a case where the information request signal received at the receiving port is always fixed to a H (high) level. The ground anomaly determination portion determines a short-circuit between a signal line and a ground in a case where the information request signal received at the receiving port is always fixed to a L (Low) level. Consequently, the anomaly region of the signal line connects the information request portion and the information response portion so that bidirectional digital communications are possible or the cause of the anomaly is specified. | 01-07-2010 |
| 20100066137 | POWER SEAT SYSTEM FOR VEHICLE - A power seat system for a vehicle, includes an operational switch configured to be operated by an occupant for changing positions and attitudes of a vehicle seat whose positions and attitudes are electrically adjusted, a sensor portion positioned in the vicinity of the operational switch and detecting a hand of the occupant approaching the operational switch without contacting the hand of the occupant, and a control portion changing the positions and attitudes of the vehicle seat by actuating an actuator on the basis of an output from the operational switch, the control portion configured to display an operational display indicating adjusting portions and directions of the vehicle seat, which is adjustable by means of the operational switch on the basis of the output from the sensor portion, at an display device provided in a vehicle. | 03-18-2010 |
| 20100243351 | DRIVE UNIT FOR MOVABLE MEMBER - A drive unit for a movable member includes the movable member adjusting aerodynamic characteristics of a vehicle while the movable member is changing a position thereof, an electric motor operating the movable member, a preventing device preventing the movable member from operating beyond a specified operating range by making contact with the movable member, and a controlling device supplying an electric power to the electric motor for a reference time and operating the movable member from a first end to a second end of the specified operating range, the controlling device correcting the reference time on the basis of an external factor that affects an operating speed of the movable member. | 09-30-2010 |
| 20110218713 | VEHICLE CONTROL APPARATUS AND CONTROL METHOD THEREOF - A vehicle control apparatus includes a drive unit that drives a mechanism provided in a vehicle, an operating portion that is operated by an occupant and instructs the drive unit to drive, a collision predicting portion that predicts a collision, and a control portion that controls the drive unit. The control portion controls the drive unit to place the mechanism in a predetermined state when the collision is predicted by the collision predicting portion, and controls the drive unit to vary a driving speed of the drive unit when the operating portion is operated while the drive unit is being controlled. The invention also relates to a control method of this vehicle control apparatus. | 09-08-2011 |
