The invention discloses a balancing gyroscope mechanism energy consumption control device of a two-wheel electric automobile. The balancing gyroscope mechanism energy consumption control device comprises a balancing gyroscope assembly, a bottom spherical balance weight, a balancing gyroscope rotating speed control circuit, a signal detector and a controller. The balancing gyroscope assembly comprises a balancing gyroscope and a balancing gyroscope fixing frame, wherein the balancing gyroscope is mounted on the balancing gyroscope fixing frame and can rotate, and the balancing gyroscope fixing frame is mounted on the bottom spherical balance weight. The controller controls the balancing gyroscope assembly to execute balancing gyroscope rotation action through the balancing gyroscope rotating speed control circuit. The signal detector is electrically connected with the controller, the controller outputs a rotating speed control parameter to the balancing gyroscope rotating speed control circuit according to a basic control parameter after data processing, and the balancing gyroscope rotating speed control circuit regulates the rotating speed of the balancing gyroscope timely according to the rotating speed control parameter. The rotating speed of the balancing gyroscope mechanism can be automatically regulated at different vehicle speeds, so that a proper balancing point is achieved, energy loss is lowered, and the endurance mileage is increased.
