  • Patent number: 10514469
    Abstract: An attitude angle may be calculated with high precision. In a traveling state calculating device, receiving parts may output data for calculation using positioning signals received by antennas, respectively. A phase difference calculating part may calculate a single phase difference for every base line based on the data for calculation outputted by the receivers. An attitude angle calculating part may calculate an attitude angle using the data for calculation and the single phase difference. A calculating condition determining part may determine a contribution of the data for calculation to the calculation of the attitude angle, corresponding to the component of the attitude angle, based on a spatial relationship between the base line and the positioning satellite.

  • Publication number: 20170282786
    Abstract: A blade receives light emitted from a light source and repeats a predetermined periodic motion to scan the front of a vehicle with reflected light of the emitted light. A position detector generates a position detection signal S4 indicating a timing at which a predetermined reference point of the blade passes a predetermined position. Based on the position detection signal S4, a period calculator calculates a period Tp of the periodic motion of the blade. A light intensity calculator receives light-distribution-pattern information S3 to be formed in front of the vehicle and calculates light intensity to be generated by the light source at each time based on the position detection signal S4 and the period Tp. A driver turns on a semiconductor light source so as to obtain the light intensity calculated by the light intensity calculator at each time.
