Apparatus for determining an estimated quantity of a state of motion of a vehicle |
摘要 |
<p>A vehicle state estimating apparatus includes a slip-angle determining unit (40) which determines a slip angle of a wheel of a vehicle. A friction-coefficient determining unit (42) determines a friction coefficient between a tire of the wheel and a road. A tire characteristics unit (44) generates a lateral force of the wheel from the slip angle and the friction coefficient based on predetermined tire characteristics. A vehicle-state estimating unit (46) determines an estimated quantity of a state of motion of the vehicle based on the lateral force output by the tire characteristics unit. A vehicle-state observing unit (48) detects an observed quantity for the estimated quantity determined by the vehicle-state estimating unit. A friction-coefficient correcting unit (50) corrects the friction coefficient determined by the friction-coefficient determining unit, based on a difference between the observed quantity and the estimated quantity, so that the lateral force from the tire characteristics unit is corrected by the corrected friction coefficient. <IMAGE></p> |
