  • Patent number: 11731649
    Abstract: A high precision position estimation method through a road shape classification-based map matching implemented by a high precision position estimation system of an autonomous vehicle includes classifying a road into a straight lane, a curved lane, and a clothoid curve lane by the lane matching between a sensor lane segment and a map lane segment, generating a movement amount value calculated by applying a geometric feature-based map matching or an optimization-based map matching to the classified lane as a covariance matrix, and calculating the latitude, longitude, and traveling direction of a vehicle to be estimated by combining the covariance matrix with sensor measurement values of a vehicle speed and a yaw rate by an extended Kalman filter.

  • Patent number: 10621942
    Abstract: A display power circuit is provided. The display power circuit includes a power supply circuit that receives an input voltage and generates an output voltage to power a display. A power switching device couples the output voltage from the power supply circuit to provide a display voltage for the display. A monitor circuit generates a shut down signal based on a change of the output voltage relative to the input voltage exceeding a predetermined threshold indicating a short circuit condition of the display voltage. A control circuit disables the power switching device based on the shut down signal if the short circuit of the display voltage is detected.
