A steering angle estimation section calculates a front-wheel-side estimative steering angle and a rear-wheel-side estimative steering angle through use of wheel speeds of respective wheels, and averages these steering angles to thereby obtain an accurate estimative steering angle. It also calculates an estimative steering angle difference between the steering angles. An axial force estimation section calculates a base axial force through use of the estimative steering angle and a vehicle speed, and calculates a correction axial force which applies an axial force difference (hysteresis) to the base axial force in accordance with a turning or returning operation by a driver. The axial force estimation section adds the base axial force and the correction axial force together to thereby calculate an accurate estimative axial force. An assist computation section compares a target steering torque, which changes with the vehicle speed, and the accurate estimative axial force, and subtracts the target steering torque from the estimative axial force, to thereby calculate an assist torque.

This assist device for pulling out of a parking spot comprises: an assist control means for performing assist control to change the steering angle of a vehicle to a target steering angle; and a pulling out possibility determination means for determining whether or not the vehicle can pull out on the basis of the detection result of a forward obstacle detected by forward detection means. If it is determined that the vehicle can pull out, the assist control means performs assist control to change the steering angle of the vehicle from the target steering angle to a neutral angle or a neutral vicinity angle.

The invention relates to a limiting mechanism of a steering device of a four-wheel vehicle, which comprises a steering wheel, a steering column, a middle rod and a traversing mechanism, the two ends of the middle rod are respectively connected with the steering column and the traversing mechanism by universal joints, the traversing mechanism is provided with a body which can contain a rack and a screw rod, the two ends of the rack are respectively connected with steering pull rods which are respectively connected on pin shafts of front wheels of the vehicle, then the front wheels of the vehicle can change the steering angle with the help of the rotation of the steering wheel, and the forward direction of the vehicle can be further changed; the key points are as follows: a segment differential part is arranged in the body of the traversing mechanism, the segment differential part can arrange a shaft sleeve, the shaft sleeve can just limit the formation stroke of the steering pull rods and form the limitation of the steering angle of the front wheels, when the maximum angle of the steering of the front wheels needs to be changed by using the structure, and the change of the steering angle of the front wheels can be achieved as long as the thickness of the shaft sleeve is changed, thereby simplifying the engineering of changing the steering angle of the front wheels.

A damper control device includes a rate sensor that detects a pitching angular velocity of a vehicle body, a vehicle speed sensor, a steering angle sensor and a calculation unit that detect a roll angle and a yaw angular velocity of the vehicle body, a pressure sensor that detects a pressure of a contraction-side chamber in a front-wheel side damper, a pressure sensor that detects a pressure of a contraction-side chamber in a rear-wheel side damper, and a correction unit that corrects the pitching angular velocity. The pressures are controlled on the basis of the corrected pitching angular velocity and the pressures. The vehicle speed sensor, the steering angle sensor and the calculation unit detect the roll angle and the yaw angular velocity on the basis of a traveling speed and a steering angle.

The directions of optical axes of headlights of a vehicle are adjusted based on a steering angle by switching filters of different response speed characteristics. The filters are provided with hystereses along boundaries neighboring to each other. The filters are switched depending upon the steering angle and a steering angular velocity to vary the response of swivel control. Therefore, the start of swiveling is not quickened, the filter is not frequently switched, quick motion is suppressed and, hence, smooth motion is realized making it possible to execute a swivel control without causing discomfort.
