A power supply device includes a moving unit that moves a power supply fitting body in an insertion-extraction direction, an up-down direction, and a lateral direction that is orthogonal to the insertion-extraction direction and the up-down direction, and a controller that controls the movement of the power supply fitting body by the moving unit. A position detection device moves in linkage with the movement of the power supply fitting body by the moving unit. A power reception fitting body includes first structures extending along the lateral direction and second structures related to a central position of the power reception fitting body in the lateral direction. The first structure and the second structure are formed protruding to one side of the up-down direction with respect to a ceiling surface. The distances between the second structures and the first structures in the insertion-extraction direction are set in advance.

Vehicle charging system

A power transmission unit includes: a power transmission coil; a communication coupler that is formed in an annular shape about an axis X and arranged to surround the power transmission coil; and a shielding member that is formed in an annular shape about the axis X, and arranged between the power transmission coil and the communication coupler in an intersecting direction. The shielding member is arranged at a position along the intersecting direction to surround the power transmission coil, and shields magnetic force generated by the power transmission coil.

An integrated antenna module to be applied to an in-vehicle system includes an antenna element group that is mounted on a vehicle and is formed of a plurality of antenna elements, and the antenna element group constitutes a plurality of antennas capable of transmitting or receiving a plurality of electromagnetic waves by combining the plurality of antenna elements.

Integrated antenna module and in-vehicle system

A shield member and a power transmission unit each include a shielding wall formed annularly about an axis so as to surround a power transmission coil at a position extending along an intersecting direction. The shielding wall shields a magnetic force generated by the power transmission coil. The shielding wall is formed such that a distance between wall faces facing each other in the intersecting direction is wider at a longer distance from a first side toward a second side in an axial direction.

A communication control system includes a first communication control device that includes a switching unit, a first gateway unit, a first power supply unit, and a first housing. The switching unit is provided in a vehicle, has a plurality of ports, and distributes a signal thereto. The first gateway unit has the CPU that is coupled to any one of the ports to convert a communication protocol of a signal. The first power supply unit supplies electric power to the switching unit and the first gateway unit. The first housing accommodates the switching unit, the first gateway unit, and the first power supply unit. The CPU can execute security processing for monitoring the switching unit.

Vehicle communication control system

A non-contact power transmission device includes a resonance coil and a resonance capacitor, and includes impedance variable circuits the impedance of which can be changed. In the non-contact power transmission device, a power transmission side controller changes impedance of one of the impedance variable circuits, a power reception side controller changes impedance of the other one of the impedance variable circuits, and output impedance on a power supply side with respect to a power transmission coil unit and input impedance on a load side with respect to the power transmission coil unit are matched.
