Embodiments of the present invention provide an apparatus comprising an upper plate and a lower plate. A plurality of horizontal load cells and a plurality of vertical load cells positioned on the lower plate to measure the forces in an x-direction, a y-direction, and a z-direction. A plurality of holes provided on the upper plate. A plurality of pins are fixed on the horizontal load cells and inserted into each correspondence hole. A plurality of spherical balls placed between the horizontal load cells and the upper plate. The spherical balls are provided to determine the force in the z-direction and the movement of the upper plate in the x-direction and the z-direction. A plurality of first sensor and a plurality of second sensors are provided over the upper plate and around the upper plate over the wall, respectively.

A control method of a vehicle is configured to control an arrangement of seats in the vehicle based on a number of occupants, a number of pieces of baggage and a baggage size, where the vehicle includes: a vehicle seat including at least one of a first seat, a second seat or a rear seat; a communicator configured to receive boarding information including information about at least one of the number of occupants or the number of pieces of baggage from a user terminal; and a controller configured to change at least one of a position and a form of the vehicle seat based on the boarding information.

An acoustic system includes an interior member for a conveyance including at least one speaker; a state detection unit that detects a state of an occupant or the interior member; and a control unit that is connected to the speaker and the state detection unit, and controls the speaker. The control unit includes a state determination unit that determines the state of the occupant or the interior member based on information received from the state detection unit, and an acoustic control unit that controls, when sound is emitted from the speaker, at least one of a volume, a tempo, and a direction of the sound emitted from the speaker, based on the determined state of the occupant or the interior member.

A child detection device for a child safety seat for an automobile according to an example includes a plurality of sensors to be positioned on the child safety seat, wherein the plurality of sensors includes at least one capacitive sensor to generate analog capacitive signals. The child detection device includes a conversion circuit to convert the analog capacitive signals to digital capacitive values. The child detection devices includes a controller to identify movement of an object based on the digital capacitive values, and determine whether a child is positioned in the child safety seat based on the digital capacitive values and the identified movement.

A system for controlling the position of a vehicle seat is disclosed. The system includes in network communication, an input device, a detection system, at least one controller, and at least one controllable device. The detection system measures a current value of at least one of the recline, fore-aft, or swivel position of the seat. The input device communicates to the controllers a desired value for at least one of these seat positions. The controller compares the measured value to a limiting value and the desired value and calculates a movement factor value. The movement factor value determines the communication between the controller and the controllable device. If the movement factor value falls into a range where the seat can be moved to the desired value, the controller signals the at least one controllable device to control the adjustment of at least one of the recline position, the fore-aft position, or the swivel position to the desired value. However, if the movement factor value falls outside a range where the seat can be moved to the desired value, the controller signals the at least one controllable device to limit the adjustment of the at least one of the recline position, the fore-aft position, or the swivel of the position.

A control method of a vehicle is configured to control an arrangement of seats in the vehicle based on a number of occupants, a number of pieces of baggage and a baggage size, where the vehicle includes: a vehicle seat including at least one of a first seat, a second seat or a rear seat; a communicator configured to receive boarding information including information about at least one of the number of occupants or the number of pieces of baggage from a user terminal; and a controller configured to change at least one of a position and a form of the vehicle seat based on the boarding information.

Devices and methods for a vehicle are provided in this disclosure. A device for controlling an active seat of a vehicle may include a processor and a memory. The memory may be configured to store a transfer function. The processor may be configured to predict an acceleration of the active seat of the vehicle based on a first sensor data and the transfer function. The first sensor data may include information indicating an acceleration of a vibration source for the vehicle. The processor may be further configured to generate a control signal to control a movement of the active seat at a first instance of time based on the predicted acceleration. Furthermore, the processor may be configured to adjust the transfer function based on a second sensor data including information indicating a detected acceleration of the active seat at the first instance of time.

A vehicle seat air-conditioning device includes: a blower that is included in a seat; at least one of an inlet duct or an outlet duct, the inlet duct being a duct through which air is led to be drawn in from a surface of the seat by the blower, and the outlet duct being a duct through which the air led by the blower is discharged from a surface of the seat; and a controller that is electrically connected to the blower. The blower includes a current detection circuit that detects a current consumption of the blower. The controller determines whether an occupant is sitting on the seat, based on the current consumption detected by the current detection circuit.

In at least some implementations, the vehicle headrest assembly comprises a body with an exterior defined by an outer surface and an interior. The body includes a mount by which the body is mountable on a vehicle seat. The vehicle headrest assembly includes a power cable at least partially within the interior that is adapted to communicate with a power supply. A transmitter is carried by the body and electrically communicated with the power cable to provide a wireless power transmission. And a switch is in electrical communication with the transmitter to selectively permit transmission from the transmitter.
