A vehicle communication system includes a switching hub incorporated in a vehicle and including a switch IC and an external CPU. The switch IC includes an internal CPU and performs a transfer process of transferring information to a communication device. The external CPU is provided outside the switch IC and connected to the switch IC, and has higher information processing capability than the internal CPU. The external CPU can perform a transfer order process of ordering to transfer information to the communication device and perform a security process of securing the security of the information to be transferred when the transfer order process is performed. The internal CPU monitors the operation of the external CPU and when the external CPU is abnormal, performs the transfer order process instead of the external CPU.

Vehicle communication 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.

Power transmission unit and power transmission coil

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.

Shield member and power transmission unit

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.
