A steering bar for a lever-controlled vehicle provides for single hand operation of the lever-controlled vehicle. For example, the steering bar couples to the control levers for a zero-turn mower, providing safer, easier operation of the mower and making the mower handicap accessible. The steering bar can easily be installed on any dual steering zero turn mower. Steering is easier because turning it controlled by rotating the steering bar either right or left, with control of forward and reverse movements by pushing or pulling the bar. Speed, turning direction, or motion forward or reverse are all controlled by a single bar with a single hand. The steering bar is coupled with a selectively extensible control shaft to accommodate for the differing displacement length between the control levers during turning movements. The steering bar is coupled with the control levers with a ball and socket joint.

An apparatus for controlling a behavior of an autonomous vehicle includes: a joystick that inputs an adjustment value corresponding to an amount of manipulation by a user, and a controller to control the behavior of the autonomous vehicle based on the adjustment value corresponding to the amount of manipulation being input from the joystick.

A self-propelled roadway crack routing machine has an operator's station located on a front portion of the machine's chassis and including a forward-facing operator's seat. A driven crack routing cutter drum for routing cracks in a roadway surface is mounted on the front portion of the chassis in a location that can be monitored by a forward-facing operator while controlling machine steering and propulsion. The machine includes a steered rear wheel and unsteered front wheels. Machine steering and propulsion and implement operation may all be effected hydraulically.

A control system is disclosed for use in a zero turn vehicle, including an electric controller in communication with a pair of independent drive units. A joystick is pivotable between a plurality of pivot positions, each pivot position corresponding to a particular rotational speed and direction of each driven wheel. A plurality of driving modes stored in the controller each map a different set of speeds and directions for each driven wheel onto the plurality of pivot positions. The joystick may also rotate about a vertical axis to provide zero turn capability. In at least one driving mode, when the rotational speed of one driven wheel is zero, the rotational speed of the other driven wheels is zero, and when the rotational speed of one driven wheel is non-zero, the rotational speed of the other driven wheel is non-zero.

An integrated driving control device configured to integrally control acceleration, deceleration, shifting and steering of a vehicle, may include a knob unit, a rotating unit engaged to the knob unit and configured to control steering of a vehicle in a response to rotation of the knob unit, and a sliding unit engaged to the rotating unit and configured to control acceleration and deceleration of the vehicle in a response to sliding movement of the knob unit.

A vehicle (12) operable in manual and autonomous modes has a manual steering control unit (10) movable between a stowed position and an operative position. Movement of the steering control unit (10) as it transitions between stowed and operative positions comprises at least a component in a lateral direction of the vehicle so that when not in use, it is located laterally outside the free interior volume of the vehicle cabin (14) in the stowed position. The manual steering control unit (10) can be received within a recess (18) in a side wall region (16) of the vehicle cabin or in a central console in the stowed position.
