To generate electricity using kinetic energy of a vehicle to thereby cause an on-vehicle communication and information processor to communicate with a vehicle control data center.

Wind power generators 31, piezoelectric ceramic suspensions 32 and wheels generate electricity using vehicle travel energy. A portable information terminal 20 is connected to a data center 50 via an on-vehicle mobile wireless device 8 using the generated electric power. The terminal 20 is used to send/receive various data such as navigation data, music data, etc., to/from the data center 50 via the wireless device 8. Data on operating states of respective elements of the vehicle is collected by a wireless gate keeper 1 and sent via the wireless device 8 to the data center 50, which then delivers the data to an auto manufacture 52, etc.
