Abstract
A vehicle system includes a portable terminal and an in-vehicle device. The portable terminal is configured to perform short-range wireless communication. The in-vehicle device is configured to locate the portable terminal based on a reception strength. The portable terminal includes a transmission unit configured to change a channel among channels. A reception strength selection unit of the in-vehicle device is configured to select a particular number of reception strengths for consecutive ones of the channels. A terminal locator unit of the in-vehicle device is configured to prioritize a largest reception strength to locate the portable terminal based on the reception strength. An upper limit of the particular number is set to be higher as an interval for transmitting information from the antenna to the in-vehicle device is shorter, and a lower limit of the particular number is set based on a multipath reduction effect.
