Abstract

Vehicle communication systems, in-vehicle devices, and portable devices. A vehicle communication system includes a vehicle-mounted device and a portable device. In the vehicular communication system, the transmitting unit sequentially transmits first to third radio signals whose strengths are weakened, the measuring unit measures the strengths of the respective radio signals, and the determining unit determines the difference between any two radio signals among the radio signals measured by the measuring unit. Whether the intensity difference between them is greater than the threshold. If the intensity difference is greater than a threshold, control of the vehicle-mounted target is permitted.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims the benefit of priority from Japanese Patent Application No. 2016-187461 filed on September 26, 2016, the entire contents of which are hereby incorporated by reference. technical field [0003] One or more embodiments of the present invention relate to a vehicular communication system in which communication based on radio signals transmitted or received between an in-vehicle device mounted on a vehicle and a portable device carried by a user of the vehicle Allows or prohibits operations on objects mounted on the vehicle. Background technique [0004] There is a vehicle communication system in which communication with an object mounted on the vehicle is permitted or prohibited based on radio signals transmitted or received between an in-vehicle device mounted on the vehicle and a portable device carried by a user of the vehicle. operation (such as locking or unlocking of the door...
