Steering system for an agricultural vehicle

A steering system for an agricultural vehicle has at least one steering cylinder for changing a steering angle of the agricultural vehicle, a hydraulic main steering valve for pressurizing the at least one steering cylinder, a steering transducer for actuating the main steering valve, a steering boost for controlling an adjustment characteristic between the steering transducer and the at least one steering cylinder and a sensor system for detecting an external signal of the agricultural vehicle. The steering boost controls the adjustment characteristic on the basis of the detected external signal.

Hydraulic interrupter safety system and method
09733643 · 2017-08-15 ·

A system and method for interrupting a Global Navigation Satellite System (GNSS)-based automatic steering mode of a hydraulic steering system on a vehicle. When a steering wheel is manually turned by an operator, pressurized hydraulic fluid from a steering directional control valve activates an interrupter having an interrupter valve. The interrupter valve blocks pressurized fluid flow to the automatic steering system, thus overriding automatic steering and giving the operator full manual steering control via the steering wheel. The hydraulic interrupt system is mechanical with no electronic elements.

DRIVING SUPPORT DEVICE, DRIVING SUPPORT SYSTEM, AND DRIVING SUPPORT METHOD

In a driving support device, an image output unit outputs an image including a vehicle object representing a vehicle and a peripheral situation of the vehicle, to a display unit. An operation signal input unit receives a gesture operation by a user that involves moving of the vehicle object in the image displayed on the display unit. A command output unit outputs a command according to the gesture operation, to an automatic driving control unit that controls automatic driving.

ROAD CONSTRUCTION MATERIALS SPREADING VEHICLE

When spreading aggregate material onto a layer of bitumen/wet bitumen, when forming a road surface, the aggregate is commonly spread from a truck in reverse, potentially causing accidents and injuries. Safety is improved by providing a spreading vehicle that can be driven in the direction in which it is spreading the aggregate material. This is achieved by providing a second driving cab and driver controls at a location that would normally be considered the rearward end of the vehicle. The second driver cab is above a conveyor system conveying aggregate material from a hopper of the vehicle to a spreader box. The second driver cab allows the vehicle to be driven in the direction it is spreading material, by a driver who is facing the direction of travel, and who can see if the vehicle is about to hit anything or run into a worker in the surrounding area.
