A charge management method includes generating and storing a charge schedule related to an electric energy for charging a vehicle within an amount of suppliable electric power for charging said vehicle located in a region, wherein said vehicle includes a rechargeable battery. The method further includes storing an identification number of said vehicle in said region by an EV controlling center. The method further includes determining a propriety of charging said vehicle at a current time and location based on said charge schedule in response to detection of a signal indicating a start of a charging process of said rechargeable battery from said vehicle having said identification number.

On-board unit and electric vehicle management system

An electric vehicle management system which controls a charging amount for an electric vehicle by way of peak shift, and an on-board unit used for the electric vehicle management system are provided. Thereby, the on-board unit mounted on the electric vehicle detects a current location, and an electric vehicle management center provided on a network manages a charging schedule created in advance. Propriety of a charging operation at a current time is checked via communications between them. Charging of the electric vehicle is managed based on the charging schedule by notifying a driver of the check result through a display of the on-board unit.

An on-board unit includes a first antenna and a second antenna, a traffic data service communicating section corresponding to a traffic data service; a billing service communicating section corresponding to a billing service, a switch which switches a connection relation between each of the first antenna and the second antenna and the traffic data service communicating section and the billing service communicating section, a control section which controls the switch. When the operation mode is switched from the traffic data service mode to the billing service mode, the on-board unit is set to a switching communication mode in which one of the first antenna and the second antenna is connected with the traffic data service communicating section and the other is connected with the billing service communicating section.

On-board unit, communication method, and recording medium

A communication system includes an on-board unit adapted to a vehicle-vehicle communication and roadside equipmentperforming a roadside-vehicle communication. In communications in service channels of the vehicle-vehicle communication, one reception-only service channel in which the on-board unit only performs a reception operation is provided for a plurality of the service channels and communications in the reception-only service channel is performed at the same frequency as that of the control channels of the roadside-vehicle communication. When the vehicle-vehicle communication is performed, the on-board unit performs switching to the roadside-vehicle communication in response to detection of reception in the reception-only service channel of a radio signal transmitted from the roadside equipmentin a control channel of the roadside-vehicle communication.

Vehicle communication system, on-board unit, recording medium and communication method

A traffic information processing system includes on-board unit configured to be installed in a vehicle, an on-board unit-equipped vehicle number-detecting unit configured to detect the number of vehicles equipped with on-board unit entering a sample area based on information received from the on-board unit, a total vehicle number-detecting unit configured to detect the number of all vehicles entering the sample area, a vehicle ratio operation unit configured to calculate a value related to a ratio based on the number of vehicles equipped with the on-board unit detected by the on-board unit-equipped vehicle number-detecting unit and the number of all vehicles detected by the total vehicle number-detecting unit, and a total vehicle number-estimating operation unit configured to calculate a total number of vehicles in the zone.
