| A drive arrangement in a vehicle having front and rear ground engaging means and steering means, has a differential transmission, a differential lock, a planetary final drive on each side of the vehicle and a motor acting onto one member of the planetary final drives. The motor is controlled depending on the steering angle such, that it provides for a difference in the drive speed on the left and the right side. | ||||||
| 132 | MULTI-MODE STEERING CONTROL FOR A VEHICLE | US16102517 | 2018-08-13 | US20180346020A1 | 2018-12-06 | Thomas D. Bebernes; Thomas A. Nichols; David V. Rotole; Walter C. Wright |
| A steering system and method is described for a vehicle having steerable front and rear wheels, and a steering input device for receiving manual steering input. Front and rear hydraulic steering devices may be coupled, respectively, to the front and rear wheels. Front and rear valve assemblies may be configured, respectively, to steer the front and rear wheels. In a manual steering mode, the front valve assembly may be disabled with respect to the front steering device, and the front hydraulic steering device may steer the front wheels based upon the manual steering input. In a rear steering assist mode, a rear steering command may be determined based upon the manual steering input, and the rear wheels steered based upon the rear steering command. In an automated steering mode, the front and rear wheels may be automatically steered based upon a target path of travel for the vehicle. | ||||||

| Systems for controlling the speed and direction of vehicles such as tractors, including vehicles that have low to zero turning radius capability. Systems include steering and speed coordination systems that control the direction and speed of rotation of vehicle drive units. | ||||||

| A vehicle steering system includes a steer detection apparatus configured to detect a steered position of a steer wheel assembly relative to a steer axle. The steered position corresponds to a direction of turn of a vehicle. A brake actuator is configured to actuate a braking system of the vehicle, and the braking system is configured to brake a first drive wheel assembly independently from a second drive wheel assembly mounted to a drive axle. The first drive wheel assembly is located on a side of the vehicle corresponding to the direction of turn. The system further includes a linkage assembly operatively coupling the steer detection apparatus to the brake actuator. In response to the steered position detected by the steer detection apparatus, the brake actuator actuates the braking system to brake the first drive wheel assembly. | ||||||

| A steering system and method are described for a vehicle having steerable wheels. A steering device may be coupled to one or more of the wheels. A parked state of the vehicle and a present orientation of the hydraulic steering device may be determined. The present orientation of the steering device may be compared with a neutral orientation of the steering device. Based upon a determined parked state of the vehicle and the comparing of the present and neutral orientations of the steering device, the steering device may be moved from the present orientation toward the neutral orientation. | ||||||

| Vehicle control systems that can be used, for example, to configure a vehicle (e.g., a lawn tractor or riding lawn mower) to make low- to substantially zero-radius turns. Some of the present vehicle control systems utilize at least one steered wheel position sensor to generate a signal that indicates the actual position of the steerable structure (e.g., wheel) to which the sensor is coupled, rather than a projected or anticipated position of that steerable structure. Vehicles that include such control systems. | ||||||

| Vehicle drive control systems, such as those, for example, configured to permit a vehicle to direct power to at least one drivable element (such as, for example, via a drive shaft, a supplemental drive, or a battery) to assist the vehicle in making a low-radius turn. | ||||||
| 138 | Power plant | US15117369 | 2015-06-10 | US09671016B2 | 2017-06-06 | Shigeru Nakayama |
| When a second member of a power plant is in a first position with respect to a first member, a first communication port communicates with a fluid pressure supply source and second and third communication ports communicate with first and second pressure chambers of a fluid pressure motor. The second and third communication ports are shut off from a fourth communication port connected to a reservoir. Different positions of the second member result different communication and shut off relationships among the first to fourth ports. The first to fourth communication ports are provided in a plurality of communication port groups each formed by the first to fourth communication ports. | ||||||

| An agricultural working machine has a first axle and a second axle, multiple ground-engaging means disposed at the first and second axles that are at least partially drivable by a drive engine or are steerable using steering-knuckle steering, a steering-angle sensor disposed at a steerable ground-engaging means for detecting a set steering angle (δth) and a steering brake for the selective braking of one or more drivable, ground-engaging means for steering support. A control unit controls and regulates the at least one steering brake based on a steering angle (δth, δtat) or a slip angle (α) of at least one of the steerable ground-engaging means. | ||||||
| 140 | ZERO TURN MOWER STEERING SYSTEM | US14689254 | 2015-04-17 | US20160302356A1 | 2016-10-20 | Robert D. Haun |
| A zero turn mower steering system including left and right motion control levers independently pivotable between forward, neutral and reverse positions to rotate left and right rear drive wheels respectively at forward, neutral and reverse speeds. Left and right position sensors on the left and right motion control levers provide electronic signals to an electronic controller that provides a left front wheel steering angle signal and a right front wheel steering angle signal. Each steering angle signal is based on a distance the electronic controller calculates from each of the left and right rear drive wheels to an instantaneous center point of a turn. | ||||||
