The self-powered active suspension, where the actuator produces force using energy generated in the suspension to achieve zero power consumption, is introduced. The method to design the active controller based on the energy balance analysis is presented. The system has been applied to the suspension systems of the truck and the rubber tired vehicle for the automated guideway transit. The feasibility of the system is examined through the laboratory tests and the numerical simulations. The energy harvesting in the rotating tire using the stochastic resonance occurred in the multiple stable system is introduced. To monitor the condition between the tire and road surface, installing sensors in the tire is demanded. As supplying energy is not easy, energy harvesting in the rotating tire is useful. The phenomenon of the stochastic resonance is presented in the basic model and the method to apply it to the energy harvesting in the rotating body is explained. The power to be generated is examined through the running test of the vehicle.
