Abstract
Abstract An apparatus is provided for ergonomically controlling a vehicle. A vertical control stick provides acceleration, brake, and turn functions in the vehicle. The apparatus may include a pivotal attachment or a slidable attachment at the lower end of the stick to a fixed surface in the vehicle. The stick is restricted to movement along the line of direction of the vehicle, both forward and rearward, of a neutral stick position. A braking means is interconnected with the stick such that movement of the stick forward from the neutral stick position causes vehicle braking. Similarly, an acceleration means is interconnected with the stick such that movement of the stick rearward from the neutral stick position causes vehicle acceleration. A steering collar on the stick is included such that the collar may be manually rotated about the longitudinal axis of the stick in both clockwise and counterclockwise directions from a neutral collar position. Clockwise rotation of the collar away from the neutral collar position causes the vehicle to turn to the right, and counterclockwise rotation of the collar away from the neutral collar position causes the vehicle to turn to the left. A console is mounted on an upper end of the stick. The console has a control panel with a plurality of controls for thumb actuation so that a single hand can provide manual control of the stick, the collar, and the control panel. The controls may include turn signal controls, horn actuation controls, low-high headlight beam controls, windshield wiper controls, windshield washer controls, speed range controls, gear range selection controls, and the like. Status indicators are further included on the console to provide vehicle status information.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
212 words
An ergonomic apparatus for controlling a vehicle comprising an approximately vertical control stick providing acceleration, brake and tum functions in the vehicle and including means for attachment of the lower end of the stick to a fixed surface in the vehicle such that the stick is restricted to movement along the line of direction of the vehicle both forward and rearward of a neutral stick position, means for steering the vehicle providing a rotatable collar on the stick such that the collar may be manually rotated about a longitudinal axis of the stick in both clockwise and counterclockwise senses from a neutral collar position, a braking means and an acceleration means interconnected with the stick such that said movement forward of the neutral stick position causes vehicle braking, the braking force being proportional to the magnitude of stick movement, said movement rearward of the neutral stick position causes vehicle acceleration, the accelerating force being proportional to the magnitude of stick movement, said collar rotation clockwise of the neutral collar position causes vehicle turning to the right side, said collar rotation counterclockwise of the neutral collar position causes vehicle turning to the left side, the degree of the right and left side turning being proportional to the magnitude of rotation of the collar.
Claim 2
Dependent Claim
212 words
An ergonomic apparatus for controlling a vehicle comprising an approximately vertical control stick providing acceleration, brake and tum functions in the vehicle and including means for attachment of the lower end of the stick to a fixed surface in the vehicle such that the stick is restricted to movement along the line of direction of the vehicle both forward and rearward of a neutral stick position, means for steering the vehicle providing a rotatable collar on the stick such that the collar may be manually rotated about a longitudinal axis of the stick in both clockwise and counterclockwise senses from a neutral collar position, a braking means and an acceleration means interconnected with the stick such that said movement forward of the neutral stick position causes vehicle braking, the braking force being proportional to the magnitude of stick movement, said movement rearward of the neutral stick position causes vehicle acceleration, the accelerating force being proportional to the magnitude of stick movement, said collar rotation clockwise of the neutral collar position causes vehicle turning to the right side, said collar rotation counterclockwise of the neutral collar position causes vehicle turning to the left side, the degree of the right and left side turning being proportional to the magnitude of rotation of the collar.
