Abstract
A position estimation method for estimating a position of a mobile terminal includes: an acquisition step of acquiring distance values and radio wave intensity values between communication devices provided in a vehicle and the mobile terminal by communicating the communication devices with the mobile terminal; a communication availability determination step of determining that a corresponding communication device is communicable when the distance value is not more than a first value and the intensity value is not less than a second value; an area determination step of, based on a result of the communication availability determination step and communication maps mapping communicable ranges of the communication devices, determining an area where the mobile terminal exists by superimposing the communication maps; and an estimation step of estimating the position of the mobile terminal based on a result of the area determination step.
