Abstract:
1. A vehicle-behavior detecting apparatus comprising: a steering-angle detecting device detecting a steering angle of front wheels; a vehicle-speed detecting device; a yaw-rate detecting device detecting a yaw rate of the vehicle; a longitudinal-acceleration detecting device detecting a longitudinal acceleration; a first-yaw-moment calculating unit calculating a first yaw moment, based on a linear bicycle model, from a vehicle speed detected by the vehicle-speed detecting device, the steering angle detected by the steering-angle detecting device, and the yaw rate detected by the yaw-rate detecting device; a second-yaw-moment calculating unit calculating, based on the linear bicycle model, a second yaw moment, in which a longitudinal load shift is taken into consideration, from the vehicle speed, the steering angle, the yaw rate, and the longitudinal acceleration; and a variation-value calculating unit calculating a variation value in the yaw moment due to the longitudinal load shift, by subtracting the second yaw moment from the first yaw moment.
