Abstract: A vehicle drive and control system includes an input shaft driven by a prime mover and extending into a housing to drive a generator. An electric motor powered by the generator drives an output axle, which may be a single axle extending out one side of the housing, or a through shaft extending through the electric motor and out both sides of the housing. The input shaft may be parallel to the axle. A power controller is configured to back-drive the generator when certain predetermined conditions are met. A motor controller may control an output of the motor based on input received via an operator control device, and the motor controller is configured to operate the motor as a generator under certain operating conditions. The transaxle includes a common housing in which the power generator, the motor, and controllers for the generator and electric motor are disposed.

Abstract: A zero turn radius vehicle with a single steered wheel is described. The vehicle may include a pair of power transfer mechanisms driving a pair of wheels, an operator control mechanism for controlling the steering, speed and direction of the vehicle and a controller in communication with the operator control mechanism. A steerable wheel is located adjacent the front of the vehicle frame, on a first side of the vehicle frame and an electric actuator is connected to the controller for steering the front steerable wheel. A second, non-steerable front caster wheel is located on a second side of the vehicle frame. The controller controls the pair of power transfer mechanisms and the electric actuator based on operator input to the operator control mechanism.

Abstract: An electronic drive control system for a vehicle having a right and left drive wheels and a pair of actuators engaged to respective control arms of the associated variable drive units. A pair of speed sensors are in electrical communication with the respective variable drive units and a controller. The controller receives signals from the speed sensors and determines at least one operational output of each variable drive unit based on the received signals, calculates adjustments to at least one of the actuators and adjusts at least one of the actuators to move the respective control arm of the drive unit to effectuate the desired operational output of the variable drive units.
