Abstract

A vehicle traction device having at least one energy storage component; at least one traction component; at least one acceleration sensor including a pressure sensor, a motion sensor, a gyroscopic sensor, an accelerometer, and/or a piezoelectric sensor; and at least one deceleration sensor including a pressure sensor, a motion sensor, a gyroscopic sensor, an accelerometer, and/or a piezoelectric sensor. The at least one acceleration/deceleration sensor is responsive to an operator input, and when the operator input is applied to the at least one acceleration/deceleration sensor, the energy traction device is signaled to transfer energy from the at least one energy storage component to the forward propulsion of the vehicle, or vice versa, using the at least one traction component. The vehicle traction device may be incorporated into, for example, a wheel, a motor, and/or a transmission.
