Abstract: A driving control system 1 includes a camera unit 11 and a transceiver 18 which are mounted to a vehicle 5. The driving control system 1 also includes a transceiver 74, an information recognition_ECU 72 which recognizes road traffic information based on first road traffic detection information received by the transceiver 74 through the transceiver 18, and a traveling_ECU 73 which computes control information for the vehicle 5 based on the road traffic information, which are provided to a traffic control apparatus 70 disposed in each predetermined traffic control area. The driving control system 1 also includes an E/G_ECU 23, a PS_ECU 24, and a BK_ECU 25 which are mounted to the vehicle 5 and execute driving control based on the control information received by the transceiver 18 through the transceiver 74.

Abstract: A travelling control system includes a plurality of vehicles each including a controller, a server including a generator configured to generate a travelling control information for the plurality of vehicles, a predictor configured to predict a merging interference between a first vehicle travelling from a merging road toward a main road and a second vehicle travelling on the main road, a sender which is provided in the first vehicle to send an interference suppressing request, and a receiver which is provided in the second vehicle to receive the interference suppressing request. The controller of the second vehicle travelling on the main road is configured to execute interference suppressing control of suppressing an approach of the second vehicle to the first vehicle travelling from the merging road to the main road, in a case that the receiver receives the interference suppressing request from the first vehicle.

Abstract: A feed element and a parasitic element are formed on the ends of a board. The feed element is formed on the surface of the board, and the parasitic element is formed on the back of the board. A circuit region of the board is mounted with a radio communication circuit. The feed element is connected with a signal line, and the parasitic element is connected with a GND line. A slit is provided between the feed element and the circuit region, and a slit is provided between the parasitic element and the circuit element.

Abstract: A communication apparatus includes a transmitter for transmitting an outgoing radio signal, a receiver for receiving an incoming radio signal, and a controller for controlling a direct current carrier leakage, and the transmitter includes a first multiplier for multiplying a first carrier-wave signal by an In-phase signal, a second multiplier for multiplying a signal having the similar frequency as and a phase shifted by 90 degree with respect to the first carrier-wave signal by a Quadrature-phase signal, and a transmitting amplifier for amplifying a composite signal multiplied by the In-phase signal and the Quadrature-phase signal, respectively, and outputting the composite signal for forming the outgoing radio signal.
