  • Algorithm for determining travel direction for automobiles
    Patent number: 6577948
    Abstract: A method of determining the direction of travel of a vehicle independent of the transmission gear position. A plurality of yaw rate values are utilized, which are summed or integrated over a period of time to generate a plurality of yaw rate sum values. The sign of each yaw rate sum value is compared. This comparison of the signs of each yaw rate sum value results in a confidence value that is used to determine the direction of travel. Preferably, the actual gear position, a calculated gear ratio, and the vehicle's velocity are used to build confidence in the resulting confidence value given above.
