  • Publication number: 20190202465
    Abstract: If a controller determines the calculation of a measured vehicle body velocity is possible, the controller calculates the measured vehicle body velocity as an estimated vehicle body velocity to conduct update processing for a K table and an AB table. If the controller determines the calculation of the measured vehicle body velocity is impossible, the controller extracts a conversion coefficient from the K table based on a detected running state while extracting a sensitivity coefficient and an offset coefficient from the AB table based on the temperature by a temperature sensor. The vehicle mounted apparatus calculates an axle pulse-based vehicle body velocity from the extracted conversion coefficient while calculating an acceleration-based vehicle body velocity from the extracted sensitivity coefficient and offset coefficient.

  • Patent number: 10237652
    Abstract: A volume control device controls reproduced sound levels at the listening position set to the seat in the vehicle compartment, and gives the phase difference to an externally inputted sound signal, and supplies the sound signals to two speakers. Here, the phase difference is calculated, at a frequency lower than a predetermined frequency, for sound signals reproduced by the speakers in front of and behind the listening position. Also, the phase difference is calculated to make a reproduced sound level at the listening position smaller than the reproduced sound level when the sound signal is reproduced by either one of the pair of speakers. Preferably, the listening position includes two evaluation points, and the reproduced sound level at the listening position is a sum of the reproduced sound levels at the two evaluation points. Thus, the reproduced sound may become small at an arbitrary listening position in the acoustic space.
