摘要

A communication system includes an in-vehicle device including an in-vehicle device communication unit that performs wireless communication using a short-range wireless communication method, and an in-vehicle device control unit that executes control for transmitting a request signal; a mobile terminal including a mobile terminal communication unit that performs wireless communication using a short-range wireless communication method; and a mobile device including a mobile device communication unit that performs wireless communication using a short-range wireless communication method, a mobile device control unit that executes control for transmitting a response signal to a request signal from the in-vehicle device, and a mobile device transmission unit that transmits a response signal to the in-vehicle device according to the control by the mobile device control unit. The in-vehicle device control unit executes control for transmitting the request signal when the short-range wireless communication network is formed with the mobile terminal and the mobile device.
