Abstract: PURPOSE:To facilitate a job for transfer operation by making a selector valve so as to be changed over to the manual steering side from the automatic steering side by means of longitudinal differential pressure in a four-way valve at time of operating a steering gear, in a steering system capable of selecting the manual steering and the automatic steering on the basis of operation of a transfer operator. CONSTITUTION:A control valve 18 consisting of a four-way valve is installed in space between both lower side and upper side steering shafts 13a, 13b, while the supply and exhaust ports 18b, 18c are connected to ports 30g1, 30g4 of a 8-port two position hydraulic driving selector valve 30 and a exhaust port 18d to a port 30g3, respectively. Ports 30g6, 30g8 of the selector valve 30 are connected to symmetrical oil chambers 22a, 22b of a power cylinder 22, and a port 30g7 is connected to a reservoir 23. In order to select a valve position of the selector valve 30, two cylinder chambers 30c, 30d are installed, while both symmetrical oil chambers 30d2, 30d1 being partitioned off by a piston 30d3 of a cylinder chamber 30d are connected to a hydraulic pump 21 and the reservoir 23 via a 4-port three-position solenoid driving control valve 26, and this control valve 26 is controlled by an automatic steering control part 24.

Abstract: PURPOSE:To prevent a total control system from instantaneously falling into a control stop by providing a condition giving means for giving a condition that a feedback gain in feedback compensation calculation, related to a physical quantity in which a fault is detected, is set substantially to 0. CONSTITUTION:In order to calculate a steering angle of front and rear wheels so as to obtain a relation of no interference in which steering of the front and rear wheels being based on each physical quantity is prevented from mutually generating the other physical quantity, each physical quantity is generated independently even for stopping a control. Also when improper action of a physical quantity detecting means is detected by a fault detecting means, the above calculation is continued by giving a condition that a feedback gain of the physical quantity, in which this fault is detected, is substantially set to 0.

Abstract: PURPOSE:To perform a deflection control as desired by providing a correction arithmetic means for performing arithmetic operation in a manner wherein the first and second physical quantities, generated in a vehicle, are in no interference with each other. CONSTITUTION:An input steering amount by a steering handle is detected by a handle steering amount detecting means. A speed of a vehicle is detected by a car speed detecting means, and the first physical quantity, related to rotation about a vertical axis generated in the vehicle, is detected by a first physical quantity detecting means. While the second physical quantity, related to the displacement in a lateral direction generated in the vehicle, is detected by a second physical quantity detecting means. Next a handle steering amount, car speed, first and second physical quantities detected by a correction arithmetic means are input and the detected first and second physical quantities are input and, when each steering amount of front and rear wheels is calculated so as to eliminate each displacement between the detected first and second physical quantities and the first and second target physical quantities determined by the detected handle steering amount and car speed, this calculation is performed so that the first and second physical quantities, generated in the vehicle, are not in interference with each other.

Abstract: PURPOSE:To improve steering responsiveness and eliminate a kickback by providing a control valve controlling the feed or discharge of the working oil to a power cylinder in response to the relative displacement between the first valve member and the second valve member and providing a load mechanism mechanically connected to a steering handle. CONSTITUTION:When a steering handle 11 is rotated, a valve sleeve 17a (first valve member) is displaced to generate relative displacement between it and a valve sleeve 17b (second valve member), a control valve 17 controls the feed or discharge of the working oil to a power cylinder 15, the cylinder 15 displaces a rack bar 12 in the opposite direction to the rotation of the handle 11, and the right and left front wheels FW2 and FW1 are steered in the rotation direction of the handle 11. When the relative displacement between the sleeves 17a and 17b is eliminated, the valve 17 stops the feed or discharge control of the working oil, steering of the right and left front wheels is stopped, and the right and left front wheels are steered in response to the rotation quantity of the handle 11. A load mechanism 23 excites the handle 11 to the neutral position, thus a reaction force against the rotation is applied to the handle 11.

Abstract: PURPOSE:To improve short turning ability during low speed running and running stability during high speed running by a method wherein when a car speed is low, rear wheels are steered in a high steering angle arc, and meanwhile, with the increase in a car speed, control is effected so that the rear wheels are further strongly energize to bring them into a neutral state. CONSTITUTION:With a handle 14 steered, left and right front wheels FW1 and FW2 are steered in the same direction as a steering direction trough a rack bar 11. A plurality of cables 73 and 74 are selectively pulled, and left and right rear wheels RW1 and RW2 are steered in the same phase as or a reverse phase to those of the front wheels FW1 and FW2 through a relay rod 31. In this case, when a rear wheel steering cancel switch 56 is in an OFF-state, based on a detecting signal from a car speed sensor 57, a plurality of throttle openings of an electromagnetic flow dividing valve 54 are controlled by an electric control circuit 55. With the increase in a car speed, the feed of working oil to a power cylinder is decreased, and displacement in the direction of the axis of a relay rod 31 is suppressed.
