Abstract: The left and right rear wheels 16B are controlled independently, and the traveling direction of the vehicle 10 is changed (turned) with the speed difference thereof. In other words, conventionally, it was necessary to provide a steering wheel, and the passenger was required to constantly operate such steering wheel. Nevertheless, since merely a designation of the turning direction by previously moving the operation stick 92 to the left or right will enable an automatic turn at an optimum curvature, the passenger is freed from complicated steering operations. Moreover, since the left and right independent control is implemented with PLL control, a highly precise and highly responsive turn is realized.

Abstract translation: 左右后轮16B被独立地控制，并且车辆10的行驶方向以其速度差而变化（转动）。 换句话说，通常需要提供方向盘，并且乘客需要不断地操作这种方向盘。 然而，由于仅通过将操作杆92向左或向右移动来指定转向方向将能够以最佳曲率进行自动转弯，所以乘客不需要复杂的转向操作。 此外，由于利用PLL控制实现左右独立控制，因此实现了高度精确和高响应的转弯。

Abstract: The vehicle rack and pinion steering system has an elongated rack bar. Tie rod connectors are provided on the ends of the bar. A rack gear teeth section is provided on the rack bar in a position parallel to and spaced from the rack axis. A cylindrical bearing surface is on the opposite side of the rack axis from the rack gear teeth section. The bearing surface has a fixed radius and is concentric with the rack axis. The rack section width is at least twice the fixed radius. Secondary bearing contact surfaces join the bearing surface, extend toward the rack gear teeth section and diverge from each other. Contact between the bearing and surface shifts the point of convergence of forces on the rack toward the pitch point.

Abstract: A steering angle sensor arrangement for determining the steering angle of a steering wheel arrangement has an incremental code track and a sensing device. The code track is assigned to either of a rotatable portion of the steering wheel or a fixed portion. The sensing device for sensing the code track can be assigned to the other assembly. The sensing device generates an incremental signal from which the steering angle can be determined. At the incremental track has at least one reference mark, which modifies the incremental signal for determining the absolute position of the steering wheel.

Abstract: A method and apparatus for controlling the steering of a trailing section of a multi-sectioned vehicle is described. The trailing section follows the path of the first section. Data is acquired by a controller from sensors on the various sections. The controller then processes this data, generating a configuration needed for the controller-steered wheels to follow a path approximately equivalent to the path taken by the first steered section. Power is then applied by some means to steer these controller-steered wheels, forcing them into the desired configuration. The complexity of the control system can be varied with different algorithms providing alternative steering patterns as desired. This system can be extended with more trailing sections without necessitating more than minor changes to the control algorithms.

Abstract: A vehicle comprises a steering operation device, a pair of running-driving wheels, which differentially drive when the steering operation device is manipulated, a pair of steerable running wheels interlocking with the steering operation device, and a steering mechanism interposed between the steering operation device and the pair of running-driving wheels. The steering mechanism includes a pair of drive gears interlocking with the steering operation device and a pair of follower gears interlocking with the respective steerable running wheels. The drive gears mesh with the respective follower gears so as to control lateral turning of the respective steerable running wheels. A gear radius of the drive gear may be greater than that of the follower gear meshing with it. A gear ratio between the mutually meshing drive and follower gears may be variable. The lateral turning centers of both the steerable running wheels may coincide with each other, and further coincide with a lateral turning center of the vehicle body caused by differential rotation of the running-driving wheels.

Abstract: A controller controls right and left wheel drive motors based on a tire angle detected by a tire angle sensor such that the angular velocities of a pair of drive wheels about the center of a turn of the vehicle are equal to each other. The controller determines a steering speed of a steered wheel at the time a steering wheel is turned, from the tire angle detected by the tire angle sensor. Based on the steering speed, the controller controls a hydraulic pressure control motor, enabling a hydraulic pump to supply working fluid at a rate corresponding to the steering speed through a priority valve to a steering cylinder. With this arrangement, the vehicle is allowed to make a smooth turn.
