  • Patent number: 11159041
    Abstract: 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.

  • Patent number: 10442317
    Abstract: 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.

  • Patent number: 9490416
    Abstract: 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.
