1. An electronic drive control system for a vehicle having a right side actuator engaged to a first control arm of an associated right side variable drive unit, a left side actuator engaged to a second control arm of an associated left side variable drive unit, an accelerator, and a steering mechanism, the control system comprising:

  • a right speed sensor in electrical communication with the right side drive unit;

    a left speed sensor in electrical communication with the left side drive unit;

    an accelerator signal device in electrical communication with the accelerator;

    a steering signal device in electrical communication with the steering mechanism;

    a controller in electrical communication with the right speed sensor, the left speed sensor, the accelerator signal device, the steering signal device, and the right and left side actuators;

    wherein the controller;

    receives a signal from the right speed sensor, the left speed sensor, the accelerator signal device, and the steering signal device;

    determines at least one operational output of the right side drive unit and the left side drive unit based on the received signals;

    calculates adjustments to at least one of the right side actuator and the left side actuator; and

    adjusts the at least one of the right side actuator to move the first control arm of the right side drive unit and the left side actuator to move the second control arm of the left side drive unit to effectuate the at least one operational output of the right side drive unit and the left side drive unit.
