A communication system in vehicle according to an aspect includes a transmission unit and a receiving unit. The transmission unit includes a modulation unit that generates a PWM signal having a predetermined duty ratio, an output unit that outputs the PWM signal, a feedback unit that feedbacks the PWM signal, and a transmission controller that controls the modulation unit using the feedbacked signal. The receiving unit includes a reception controller that determined whether to drive a load based on the PWM signal and a switching unit that is turned on or turned off based on the determination of the reception controller.

Communication system in vehicle and communication method using the same

An apparatus for controlling a headrest for a vehicle seat includes: a headrest disposed at an upper side of a vehicle seat and that moves to an upper end or a lower end; a slider that moves the seat forward or rearward; a recliner that rotates the seat forward or rearward; a drive unit that operates the headrest, the slider and the recliner; a sensor unit connected to the drive unit and that detects a position of the headrest, a position of the slider and a rotation angle of the recliner; an input unit that receives an inputted operation instruction to operate the slider and the recliner from a user; and a control unit that controls the drive unit based on the inputted operation instruction and operates the headrest upward or downward in accordance with the detected position and the detected rotation angle.

Apparatus and method for controlling headrest of vehicle seat

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 invention prevents the virtual limit setting information from being initialized by expanding the position of the virtual limit to a wider range than the conventional one when the hard stop situation occurs in the before/after section of the virtual limit. For the purpose, the present invention provides a virtual limit correction device of power seat for vehicle comprising a switch for seat operation; and a seat operation control unit for correcting the virtual limit position by moving the end position of the track by using the track end position and the compensation position as compensation regions if a hard stop situation occurs in the front/rear direction based on the initially set virtual limit point during the movement of the power seat according to the switch operation.

Virtual limit correction device of power seat for vehicle, and correction method therefor

A piezoelectric drive circuit includes a first circuit which applies a voltage to the piezoelectric element and includes a plurality of transistors. A second circuit removes the residual current of the piezoelectric element and includes a plurality of transistors, and among the transistors included in the first circuit and the second circuit, transistors operated by an input signal are simultaneously turned ON/OFF by receiving the same input signal. Thus, when using a piezoelectric element as the air valve, it is possible to reduce leakage of air.
