Abstract: A vehicle 2 is provided with an authentication system 4 which enables operating a user's terminal 3 as a key to the vehicle 2. The authentication system 4 performs authentication by means of near-field communication between the terminal 3 and a wireless authentication device 22 and operates a device 20. A determination unit 33 confirms the use state of the terminal 3 at the time when near-field communication was performed, and determines whether or not the confirmed use state of the terminal 3 satisfies a condition for stopping or restricting the key function. If the determination unit 33 has determined that the confirmed use state of the terminal 3 satisfies the condition for stopping or restricting the key function, then a processing unit 36 performs processing for stopping or restricting the key function.

Abstract: A remote control system includes a first control device, a second control device, and a remote control device. The first control device performs an operation control on a first controlled device mounted on a moving body. The second control device performs an operation control on a second controlled device installed in a building. When one of the operation control on the first controlled device by the first control device and the operation control on the second controlled device by the second control device has been performed, the remote control device causes, by a remote control, an execution of an other of the operation control on the first controlled device by the first control device and the operation control on the second controlled device by the second control device.
