  • Navigation method using a small volume of data
    Patent number: 6418375
    Abstract: The invention provides a method of routing using an offboard navigation system for motor vehicles, in which road points, at which there is a road junction, and also the road distance between adjacent road points on a calculated route are stored in a memory element in the vehicle. Preferably, only those road points which are also turnoff points are stored. The distance from the next turnoff point at which a turnoff maneuver is to be effected is determined by comparing the distance covered since the last turnoff point with a stored value for the road distance between the adjacent turnoff points. If a minimum value for the distance from the next turnoff point has not been reached, a driving instruction is output. The method requires only a small volume of data and an odometer for position finding.

  • Method for identifying a stationary state of a vehicle
    Patent number: 6411868
    Abstract: A method for distinguishing between a movement state and a rest state of a motor vehicle, in which the output signal of a sensor arranged in the vehicle is evaluated. The invention provides for the noise of the sensor signal to be evaluated in order to distinguish between the movement state and the rest state of the vehicle.
