  • Patent number: 10637380
    Abstract: Provided is a safety power window controlling method including an operation in which a ripple current detector detects a ripple current by removing high-frequency noise from an output current signal of a four-pole stator motor; an operation in which an amplifier receives a ripple current as a first input signal, receives a reference voltage as a second input signal, and outputs an amplified current signal obtained by amplifying the first input signal to a level of the reference voltage; and detecting the amplified current signal output by the amplifier as a valid signal by using at least two preset reference values.

  • Patent number: 10601220
    Abstract: A window control device for a vehicle, and a method therefor, include a driving motor configured to drive a window glass, a first sensor configured to generate one pulse signal corresponding to a rotation of the driving motor, a second sensor configured to sense a voltage signal provided to the driving motor, and a controller configured to perform a safety function based on the one pulse signal generated by the first sensor and the voltage signal sensed by the second sensor. Although a fault occurs in one of two hall sensors, the window control device may normally perform the safety function.
