    摘要： A vehicle communication system includes an in-vehicle router. The in-vehicle router includes a Wi-Fi module, a GPS, a vehicle speed acquirer, and an in-vehicle CPU. The Wi-Fi module is a module mounted on a vehicle and provided connectable to an access point of a wireless LAN. The GPS acquires vehicle position information indicating the position of the vehicle. The vehicle speed acquirer acquires vehicle speed information indicating the speed of the vehicle. The in-vehicle CPU determines the access point to be connected to the Wi-Fi module based on the vehicle position information and the vehicle speed information.

    摘要： A power transmission communication unit includes a power transmission coil, a communication antenna, an outer case, and a mold member. The power transmission coil is a coil capable of transmitting electric power without contact with a power transmission coil on a secondary side. The communication antenna is an antenna capable of performing transmission and reception of signals with a communication antenna on the secondary side. The power transmission coil and the communication antenna are assembled to the outer case. The mold member covers the power transmission coil and the communication antenna with an insulating material in a state in which the power transmission coil and the communication antenna are assembled to the outer case. The outer case includes a groove section which is formed in a concave shape and positions the communication antenna accommodated thereinside.

    摘要： A detection device includes a switch unit, the switch unit performs switching to a gain reduction state in which a gain of a loop antenna is reduced or a gain non-reduction state in which the gain of the loop antenna is not reduced in correspondence with a state of a detection target. When a wavelength of an electric wave is set as λ, the switch unit includes switch terminals for reducing the gain of the loop antenna within a range K1 on the loop antenna from a first circuit terminal to a position that is spaced away from the first circuit terminal by λ/8. In addition, the switch unit includes switch terminals for reducing the gain of the loop antenna within a range on the loop antenna from a second circuit terminal to a position that is spaced away from the second circuit terminal by λ/8.

    摘要： A vehicle communication apparatus includes a first communication device that makes an emergency call from a vehicle to the outside of the vehicle at the time of an emergency, a second communication device that makes communication differing from the emergency call, an internal power source, and a power source controller that can be connected to the internal power source and an external power source mounted on the vehicle and controls power supply to the first communication device and the second communication device. The power source controller supplies electric power of the internal power source to the first communication device and prohibits power supply to the second communication device from the internal power source when power supply from the external power source cannot be received.

    摘要： In an in-vehicle router, a narrow-range communication module (10A) is a device capable of wireless communication. A wide-range communication module is a device capable of wireless communication in the wider range than the narrow-range communication module. An Ethernet module is connected to an in-vehicle LAN in a vehicle so that communication is possible. A CPU controls the narrow-range communication module and the wide-range communication module and communicates with the in-vehicle LAN through the Ethernet module. The narrow-range communication module, the wide-range communication module, the Ethernet module, and the CPU are assembled to a housing, and the housing is provided to the vehicle.

    摘要： A vehicle detection system includes an RFID reader, a detection device, and an ECU. The RFID reader transmits a transmission signal including at least a signal that supplies power. The detection device includes a second antenna unit that mutually transmits and receives a signal to and from the RFID reader, an RFID detection circuit that is activated using the signal that supplies power included in the transmission signal received by the second antenna unit as driving power and that outputs a detection signal to the second antenna unit, and a switch circuit that switches an electrical connection portion between the second antenna unit and the RFID detection circuit to a contact state or to a non-contact state according to a state inside the vehicle. The ECU determines the state inside the vehicle on the basis of the detection signal received by the RFID reader.
