摘要： PURPOSE:To keep excellent steerability of a vehicle by suppressing the yaw rate of the vehicle when the tire condition approaches a critical level of road gripping. CONSTITUTION:A front wheel steering sensor 41, a vehicle speed sensor 42, a transverse acceleration sensor 43, and a yaw rate sensor 44 detect the front wheel steering angle, the vehicle speed, the transverse acceleration and the yaw rate respectively. A target yaw rate computing circuit 46 computes the target yaw rate based on the detected front wheel steering angle and the detected vehicle speed. A rear wheel steering control circuit 47, a wheel speed computing circuit 48, a rear wheel steering device (B) and a braking device (C) control the steering characteristics of the vehicle so that the actual yaw rate of the vehicle may follow the target yaw rate. The target yaw rate computing circuit 46 computes the side skid angle of the vehicle based on the detected vehicle speed, transverse acceleration and yaw rate, and when the side skid angle is large, the target yaw rate is reduced as the side skid angle becomes larger.

摘要： PROBLEM TO BE SOLVED: To provide an estimating device for the degree of tire grip capable of enhancing the presumptive accuracy of the degree of tire grip when a load shift occurs to a vehicle wheel.
SOLUTION: The presuming device for the degree of tire grip is equipped with a SAT estimator 16 to estimate the SAT of each front wheel, a slip angle computer 18 to presume the front wheel slip angle, a load change estimator 20 to estimate the load change of a steering wheel, a SAT model computer 22 to compute the SAT model value from the slip angle presumptive value and the load change, a braking/driving force estimator 24 to presume the braking/driving force generated on the braking/driving wheel to apply brakes or drive the vehicle, and a degree-of-grip estimator 26 to presume the degree of grip from the estimated SAT, the computed SAT model value, and the estimated braking/driving force. Because the degree of tire grip of the front wheel is estimated by estimating the load change of the steering wheel and computing the self-aligning torque model value using the load change to serve computing the self-aligning ratio, it is possible to enhance the estimation accuracy of the degree of grip in case that a load shift occurs to the vehicle wheel.

A SAT reference value calculation part 27 presumes the SAT reference value by revising the SAT model value upward, by determining that a ground length between a tire and a road surface increases and the SAT slope becomes large by the load increase and air pressure drop when the maximum value of the SAT ratio within a predetermined time exceeds the threshold.
