Abstract: An electronic control system for shifting the direction in an off road vehicle such as a lawn and garden tractor or a utility vehicle is disclosed. The control system consists of a control mechanism that activates a control circuit that in turn activates an actuator to shift the transmission. The control mechanism receives inputs from the operator and sends the appropriate output to the control circuit which thereby actuates the actuator. The control system further includes a sensor that senses neutral or not neutral. The sensor additionally supplies a neutral or not neutral input to the control mechanism. The combination of the input from the operator and the sensor indicates the direction of the vehicle.

Abstract: An arrangement which operates an automated transmission for use in the power train of a motor vehicle has an element which can transmit motion to a gear selecting and shifting member of the transmission. The element is reciprocable by a first actuator which can employ an electric and/or fluid-operated and/or mechanical drive and is responsive to signals from an electronic control unit. A second signal-responsive actuator can be utilized to index the gear selecting and shifting member, either directly or by way of the motion transmitting element, in order to actually shift into or from a selected gear and/or to cause the member and/or the element to bypass an obstacle which can arrest the member and/or the element in an intermediate position in order to shift into or from one or more gears in certain types of transmissions.
