Sideslip angle estimation apparatus and method and automotive vehicle incorporating the same

摘要

In order to enhance the accuracy of estimation of sideslip angle beta, a sideslip angle estimation apparatus calculates a first sideslip angle beta₂ 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 beta₂.
