A power seat system includes: a motor that changes a position of a power seat by performing a rotational operation; a Hall sensor that senses a change in Hall voltage according to the rotation of the motor and outputs a pulse signal; and a motor reverse rotation detection unit that monitors outputs from the motor and the Hall sensor, and detects an occurrence of a reverse pulse according to a motor reverse rotation when a motor current overshooting section and a change in pulse signal value are simultaneously detected in accordance with stop of the motor.

An apparatus for controlling a rear-seat leg support for a vehicle seat includes: a rear-seat leg support disposed at a lower side of a vehicle seat and that performs an upward-downward rotational operation and a forward-rearward slide operation; a passenger seat that performs a forward-rearward slide operation and a forward-rearward reclining operation; a drive unit that operates each of the rear-seat leg support and the passenger seat; a sensor unit connected to the drive unit and that detects a rotation angle and a slide position of the rear-seat leg support or a slide position and a reclining angle of the passenger seat; an input unit that receives an inputted operation instruction to operate the rear-seat leg support or the passenger seat; and a control unit that adjusts the slide position of the rear-seat leg support.

The present disclosure relates to a vehicle seat moving apparatus configured to control movement of a vehicle seat along a first transfer rail and a second transfer rail formed on the bottom of a vehicle so as to be spaced apart from each other in parallel and a control method thereof.

An improved system and method for controlling a moveable object associated with a mobile platform are provided. The provided system and method generates an application specific protected volume between the moveable object and a feature of the mobile platform to be protected. The provided system and method use magnetic sensing techniques to sense the moveable object when it infringes upon the protected volume, and provide control of the moveable object responsive to sensed infringement.

Vehicular control method to avoid collisions in which a smartphone is coupled to the vehicle while in a vehicular compartment. Data is generated from vehicle-resident sensors about operation of the vehicle and transferred from the vehicle to the smartphone while the smartphone is coupled to the vehicle. A communications network with another vehicle is established using the smartphone and the data transferred from the vehicle to the smartphone and data from sensors on the smartphone is transmitted via the smartphone and established communications network to other vehicle, the data including data about location and movement of the vehicle. Then, while the smartphone is coupled to the vehicle, a vehicular operational function is controlled based in part on data transmitted using the smartphone and established communications network to cause movement of the vehicle to change in order to avoid a collision with the other vehicle.

An electronic control system for vehicle seatbacks is provided. The electronic control system can detect an obstruction or a motor stall by comparing the energy consumed by a seatback motor with an obstruction threshold and a stall threshold, the threshold being selected based upon the position of the seatback. The electronic control system can additionally control the synchronous folding of two or more adjacent powered seatbacks. The electronic control system causes the motor for the lagging seatback to receive a maximum driving voltage and causes the motor for the leading seatback to receive a partial driving voltage. Once the seatbacks are in alignment, a normal driving voltage is provided to both motors.

Methods and systems for detection of removable vehicle seats may be used to indicate presence or absence of a child in the vehicle. In some examples, an alarm system includes a radio frequency (RF) transceiver and a removable seat magnetic coupling. Various actions are triggered when the parent (e.g., guardian) goes beyond a predefined range while the removable seat is within the vehicle, such as sounding an alarm on a mobile electronic device.

An actuator (110, 210) for a vehicle seat (1) includes a housing (11), a motor (12) which is fixed to the housing and includes a motor shaft (12a), a transmission (13) connected to the motor shaft, an actuator output drive (14) which is connected to the transmission, and a control unit (21). The actuator output drive includes an output element moveable towards an end position from a starting position by rotating the motor shaft in a first direction and in a reversed directionin the direction of the starting position from the end position. A carriage (15) is driven, upon movement of the output element. A position sensor detects a position of the carriage. An actuator (210) for a vehicle seat is provided, in which a position sensor (28) detects an effect of gravity on the actuator. A vehicle seat (1) with one such actuator (110, 210) is provided.

A vehicle seat adapted for use in a vehicle includes a seat rail device arranged to extend between the vehicle seat and a vehicle to mount the vehicle seat to the vehicle. The seat rail device includes a lower rail coupled to the floor of the vehicle in a fixed position, an upper rail coupled to the vehicle seat and configured to be adjustable along a longitudinal axis relative to the lower rail, and a sensor device configured to detect a least one longitudinal position of the upper rail relative to the lower rail.
