The present invention relates to a zero turning radius vehicle having at least one steerable front wheel and a multistage steering input system separately capable of steering the at least one front wheel and selectively driving the drive wheels. A front wheel steering system comprises at least one oblongated sprocket meshingly connected to a steering shaft. An engagement cam system provides the ability to selectively, independently couple the steering wheel to pump arms driving a first and second drive wheel. A steering cam shaft comprises at least one steering cam that acts on at least one bearing. Once the engagement cam system rotates the at least one bearing into place to receive the at least one steering cam, rotation of the steering cam independently alters the speed of one drive wheel in relation to the other drive wheel in response to steering input provided by the operator.

A motor control unit includes a detected steering torque correction unit that corrects the detected steering torque that is detected by a torque sensor and then subjected to a limitation process by a steering torque limiter. When the absolute value of the detected steering torque is equal to or smaller than a predetermined value, the detected steering torque correction unit corrects the detected steering torque to 0. When the absolute value of the detected steering torque is larger than the predetermined value, the detected steering torque correction unit outputs the detected steering torque without correction. A PI control unit calculates the addition angle based on the deviation of the control torque obtained through correction by the detected steering torque correction unit from the command steering torque.

A steering system for craft turns a motor from a fixed position to a secondary position. As a result, the craft turns right or left as desired by a user of the craft. A control unit instructs the steering system to turn the craft to a desired orientation. A steering motor is activated that turns a cam attached to a shaft. The shaft is attached to the motor. The cam also includes an indent and sensors to indicate when the motor is in the fixed position or a secondary position that corresponds to a maximum angle for turning the motor. The steering system returns the motor back to the fixed position when the user indicates the steering system is to stop turning, or when the secondary position is reached. The steering system returns the motor back to the fixed position without knowledge of the user. Thus, the motor stays in one of three positions unless instructed by the control unit to turn.
