Abstract: A position estimation system determines the location of a mobile device relative to a vehicle by wirelessly communicating with the device. The system includes multiple communicators installed at different positions in the vehicle, and a communication controller that manages these communicators. The communication controller collects signal reception strength and a time-of-flight related value from the mobile device. This time-of-flight value indicates the travel time of radio waves between the communicators and the mobile device. A position estimation unit corrects this time-of-flight value using a correction function based on teaching data that includes device positions, signal strengths, and time-of-flight values. The corrected time-of-flight value is used to estimate the mobile device's position. The data volume of the correction function is smaller than that of the teaching data.

Abstract: A vehicle remote operation system includes: a communication device that performs wireless communication with a mobile device; a position determination portion that determines whether the mobile device exists in an activation area; a remote operation acceptance portion that accepts a remote operation as a user instruction operation to move the vehicle; a control execution portion that performs control corresponding to a content of the remote operation; and a notification processor that notifies a user that a position of the mobile device changes from an inside of the activation area to an outside of the activation area.
