摘要： PROBLEM TO BE SOLVED: To suppress a vibration level when the vibration occurs in a steering wheel when the hysteresis is given to the steering reaction force characteristic when the steering wheel is additionally turned and when the steering wheel is returned.
SOLUTION: If the additionally turning/returning direction of a steering wheel is changed when a steering reaction force command value Tp* is on a second characteristic line (for example, B, D), an inclination of the steering reaction force command value Tp* is increased from K2 to K1. If a steering angle θh reaches an angle corresponding to the intersection of the first characteristic line with the second characteristic line, when the steering reaction force command value Tp* is on the first characteristic line (for example, A2), the inclination of the steering reaction force command value Tp* is decreased from K1 to K2. If the steering reaction force command value Tp* is in a set range in a vicinity of 0 when the steering reaction force command value Tp* is on the first characteristic line, the inclination on the first characteristic line is set to be K3 which is smaller than K1.

摘要： PROBLEM TO BE SOLVED: To evaluate highly accurately riding feeling felt by an occupant in consideration of a human sensual characteristic.
SOLUTION: A riding feeling evaluation value H is determined by a following expression based on the magnitude V of floor vibration and the magnitude S of a vehicle compartment sound: H=a(S)×V+C (C is a slice). In this case, a weighing factor a of the vibration V is changed so as to approach asymptotically toward zero, and to have a smaller absolute value, as the magnitude S of the vehicle compartment sound is enhanced. Hereby, riding feeling felt by a human is evaluated by taking a sensitivity change of a vibration felt by the human by a sound.
