  • Patent number: 9650054
    Abstract: A method and apparatus are provided for determining the location of a vehicle. According to one aspect the method and apparatus the movements of motor rotors in a vehicle are monitored and used to determine speed, travel distance and/or travel path of a vehicle may be determined.

  • Patent number: 8965691
    Abstract: A system for an autonomous vehicle is disclosed that combines information from single-channel encoders serving as wheel speed sensors on multiple wheels of the vehicle. A pattern of the outputs from the single-channel encoders is characterized while the vehicle is traveling in a first direction. A shift in the characterized pattern is associated with a change in direction of the autonomous vehicle. Such detection of changes in direction can be used to determine the position of the vehicle at low speeds or while starting and/or stopping where the vehicle can potentially rock back and forth.

  • Patent number: 8751148
    Abstract: A navigation system uses a dead reckoning method to estimate an object's present position relative to one or more prior positions. In some embodiments, the dead reckoning method determines a change in position from the object's heading and speed during an elapsed time interval. In embodiments suitable for use with wheeled objects, the dead reckoning method determines the change in position by measuring the heading and the amount of wheel rotation. Some or all of the components of the navigation system may be disposed within a wheel, such as a wheel of a shopping cart.

  • Patent number: 8615351
    Abstract: A driving assistance apparatus mounted to a vehicle is disclosed. The apparatus determines whether an amount of change in tire wheel speed of each tire wheel of the vehicle exceeds a threshold. The apparatus specifies a tire wheel crossing order, which is an order in which the tire wheels of the vehicle cross over a level difference between a road and a parking lot when the vehicle crosses over the level difference. The apparatus determines whether or not the vehicle has crossed over the level difference between the road and the parking lot, based on whether a threshold-exceeding order is identical to the specified tire wheel crossing order. The threshold-exceeding order is an order in which the amounts of change in the tire wheel speed of the respective tire wheels exceed the threshold.
