摘要： A first ECU 30 detects a steering torque applied to a steering system, estimates a self-aligning torque generated in a front wheel on the basis of the steering torque, and estimates a side force for the front wheel on the basis of lateral acceleration and a yaw rate. The first ECU 30 estimates a grip factor ε for the front wheel on the basis of a change of the self-aligning torque to the side force. The first ECU 30 judges whether the grip factor is below a second OS (oversteer) start threshold value. A second ECU 40 controls the transfer ratio according to the vehicle state when the grip factor is less than the second OS start threshold value.

摘要： A grip factor estimating apparatus includes a steering torque detecting unit M1, and an assist torque detecting unit M2. When a self-aligning torque estimating unit M6 estimates self-aligning torque generated in front wheels on the basis of detection result of the detecting unit, the quantity of influence of longitudinal force on self-aligning torque is removed on the basis of longitudinal force acting on the front wheels and estimated by a longitudinal force estimating unit M15 and a front wheel slip angle estimated by a front wheel slip angle estimating unit M9y. A grip factor estimating unit M12 estimates the grip factor of the front wheels on the basis of change in self-aligning torque in accordance with the side force.

摘要： In vehicle roll sensing of the present invention, a self-aligning torque (SAT) estimator estimates a composite value of SATs generated on tire contact patch of right and left wheels. A slip angle computer detects a vehicle speed and a steering angle and computes a slip angle of the wheel from the measured vehicle speed and steering angle. An SAT model value computer estimates an SAT model value as a composite value of SATs of the right and left wheels when no load shifts between the right and left wheels on the basis of the slip angle. A load shift ratio estimator estimates a load shift state of the right and left wheels on the basis of the composite value of the SATs of the wheels and the SAT model value. A vehicle rollover estimator estimates a rollover of the vehicle on the basis of the estimated load-shift state.
