  • Sideslip angle estimation apparatus and method and automotive vehicle incorporating the same
    Patent number: 7844383
    Abstract: In order to enhance the accuracy of estimation of a vehicle's sideslip angle, a sideslip angle estimation apparatus calculates an angle between the direction of centrifugal force acting on the vehicle body during cornering and the lateral direction of the vehicle body based on accelerations exerted on the vehicle body and acting in two different directions. A sideslip angle between the longitudinal direction of the vehicle body and the direction of travel of the vehicle is calculated based on the estimated angle.

  • Sideslip angle estimation apparatus and method and automotive vehicle incorporating the same
    Publication number: 20070173997
    Abstract: In order to enhance the accuracy of estimation of sideslip angle ?, a sideslip angle estimation apparatus calculates a first sideslip angle ?2 between the direction of centrifugal force acting on the vehicle body during cornering and the lateral direction of the vehicle body based on accelerations exerted on the vehicle body and acting in two different directions. A sideslip angle between the longitudinal direction of the vehicle body and the direction of travel of the vehicle is calculated based on the calculated first sideslip angle ?2.
