A transmission control device which receives steering inputs and speed inputs,
and produces an input for a steer transmission and an input for a drive transmission
in order to control the direction and speed of a vehicle. The transmission control
device, coupled to a steering assembly, coordinates the steering inputs with the
speed inputs. The steering assembly which includes an elongated force transmitter
operatively coupled to a steering device. The force transmitter, which is operatively
coupled to a plurality of front wheels, has a fore-aft path of movement for pivoting
the front wheels clockwise or counterclockwise. The present invention enhances
the user's control and maneuverability of vehicles.
