  • Patent number: 11493934
    Abstract: An autonomous vehicle, system and method of operating an autonomous vehicle. The system includes a communication module and a processor. The communication module sends a first set of Global Positioning Satellite (GPS) data over a first communication channel and a second set of GPS data over a second communication channel. The second set of GPS data is an authenticated data set. The processor operates the autonomous vehicle using the first set of GPS data, and compares the first set of GPS data to the second set of GPS data to verify the integrity of the first set of GPS data. A first value for a vehicle parameter based on the first set of GPS data is compared to a second value for the vehicle parameter based on data from a vehicle-based sensor. The first set of GPS data is rational when the difference is less than a selected threshold.

  • Patent number: 10402664
    Abstract: A processing apparatus includes a distance image acquirer, a moving-object detector, a background recognizer. The distance image acquirer acquires a distance image containing distance information of each pixel. The moving-object detector detects a moving object from the distance image. The background recognizer generates a background model in which a stationary object recognized as background of the moving object is modeled, from the distance image acquired by the distance image acquirer. The moving-object detector changes a method for detecting the moving object, based on a relative positional relation between the moving object and the background model.
