Abstract

A vehicle preferential treatment system includes a controller mounted in a hybrid vehicle, and a server performing wireless communications with the controller. The controller estimates an SOC of an electric storage (not shown) and transmits the SOC to the server. When the SOC of the electric storage exceeds a reference level, the server gives a preferential treatment to the hybrid vehicle. Then, information on the preferential treatment is transmitted from the server to the controller, and is displayed on a display unit of the controller.
