A method for adjusting the position of a steered wheel of a vehicle includes detecting a steering position value of a steering control device of a vehicle such that the steering position value corresponds to an angular position of the steering control device; calculating a traction speed breakpoint at or above which steering desensitization may occur; and defining a maximum commencement steer angle at or below which steering desensitization may commence. The method also includes determining if the angular position of the steering control device or an angular position of the steered wheel is equal to or less than the maximum commencement steer angle; detecting a traction speed of one of a traction motor or a traction wheel of the vehicle; determining if the traction speed is equal to or above the traction speed breakpoint; and calculating, by the processor, a steering desensitization value when the angular position of one of the steering control device or the steered wheel is equal to or less than the maximum commencement steer angle and the traction speed is equal to or above the traction speed breakpoint.

The bulge extends towards the one or more gripping sections when the at least one operating element is in a rest position and the at least one operating element is pivotable about the cylindrical body axis by exerting a force against the bulge.

A method for adjusting the position of a steered wheel of a vehicle includes detecting a steering position value of a steering control device of a vehicle such that the steering position value corresponds to an angular position of the steering control device; calculating a traction speed breakpoint at or above which steering desensitization may occur; and defining a maximum commencement steer angle at or below which steering desensitization may commence. The method also includes determining if the angular position of the steering control device or an angular position of the steered wheel is equal to or less than the maximum commencement steer angle; detecting a traction speed of one of a traction motor or a traction wheel of the vehicle; determining if the traction speed is equal to or above the traction speed breakpoint; and calculating, by the processor, a steering desensitization value when the angular position of one of the steering control device or the steered wheel is equal to or less than the maximum commencement steer angle and the traction speed is equal to or above the traction speed breakpoint.

A modification system is provided for modifying the steering ratio for a vehicle having a tiltable telescopic boom arm (6). The vehicle has steered wheels (11), a steering wheel, and a steering transmission device serving to transmit steering movement between the steering wheel and the steered wheels (11) with a steering ratio R=Alpha/Beta. Beta is the steering angle of the wheels, and Alpha is the turning angle of the steering wheel. The system includes a sensor configured to determine a parameter relating to the telescopic arm. A control module controls the steering ratio that is configured to modify the steering ratio R as a function of the parameter relating to the telescopic arm. A wheeled vehicle is provided, fitted with such a steering ratio modification system.

The invention relates to a modification system for modifying the steering ratio for a vehicle having steered wheels (11), a steering wheel (10), and a steering transmission device (20) serving to transmit steering movement between the steering wheel (10) and the steered wheels (11) with a steering ratio R=Alpha/Beta, where Alpha is the turning angle of the steering wheel, and Beta is the steering angle of the wheels; said system comprising a device for determining the angular speed of the steering wheel. Said system comprises a module (102) for controlling the steering ratio R configured to calculate the steering ratio as a function of the angular speed of the steering wheel (10). The invention also relates to a wheeled vehicle fitted with such a steering ratio modification system.

A materials handling vehicle comprises an obstacle scanning tool and steering mechanism, materials handling hardware, vehicle drive mechanism, and user interface that facilitate movement of the materials handling vehicle and materials handled along a travel path. The tool establishes a scan field, a filter field, and a performance field, and is configured to indicate the presence of obstacles in the filter field and the performance field. The tool executes logic to establish the performance field in response to an input performance level, scan for obstacles in the filter field and the performance field, execute obstacle avoidance for obstacles detected in the filter field, and execute a performance level reduction inquiry for obstacles detected in the performance field wherein outcomes of the inquiry comprise reduction of the performance level when a performance level reduction is available and execution of obstacle avoidance when a performance level reduction is not available.

A terminal tractor includes four independently steerable wheels, each with their own dedicated drive motor and each with their own dedicated steering device. The terminal tractor includes a controller operable to provide input commands to the drive motors and to the steering devices to operate the terminal tractor. The terminal tractor also includes a fifth wheel coupling which includes a lifting mechanism capable of raising and lowering the fifth wheel coupling a in single vertical direction.

An electrical method for centering telehandler rear wheels preferably includes an electronic control module (ECM), a rear steering cylinder, a pair of rear centering valves, a front steering cylinder, a steer mode valve, at least one steering position sensor, a steering control unit and a mode selection switch. The front and rear steering cylinders are connected to the steer mode valve. The steering control unit directs hydraulic fluid from a hydraulic pump to flow into the front and rear steering cylinders to turn the wheels. A 2W steering mode requires that the rear wheels be straight before going from a 4W steering mode into the 2W steering mode. The ECM monitors a position of the rear wheels through the at least one steering position sensor. If the wheels are not straight, the ECM will open a centering valve to straighten the rear wheels, before going into the 2W steering mode.
