Embodiment Construction

[0018] Below, refer to Figure 1 to Figure 7 , an embodiment in which the remote control system of the present invention is embodied as an electronic key system for a vehicle will be described. The electronic key system performs locking or unlocking of vehicle doors and allows starting of an engine through wireless communication between a portable device carried by a user and a vehicle. That is, when the portable device carried by the user of the vehicle exists in the outside communication area set around the vehicle or in the in-vehicle communication area inside the vehicle, the portable device will be transferred through wireless communication between the vehicle and the portable device. The identification information of the device is transmitted to the vehicle, and the vehicle performs user authentication processing using the identification information of the portable device.

Abstract

A portable device (12) that remotely controls a remote control subject (11) by receiving a response request signal (Srq) transmitted through wireless communication from a control unit (13) of the remote control subject (11) and returning a response signal (Srp) for the response request signal (Srq) to the control unit (13). The portable device is configured to set a response sensitivity (Vh) based on response sensitivity information (Srec) suitable for the remote control subject (11) transmitted through wireless communication from the control unit (13) separately from the response request signal (Srq).

Description

technical field [0001] The invention relates to portable devices and remote control systems. Background technique [0002] Conventionally, an electronic key system for a vehicle is known as described in Japanese Patent Application Laid-Open No. 2007-258877. The electronic key system automatically unlocks the car door when the user approaches the car door with a portable device, and allows the engine to start when the user enters the car. In the electronic key system, when the portable device enters the communication area set around the door or inside the vehicle, various signals are exchanged between the vehicle-mounted device and the portable device through wireless communication. The in-vehicle device electronically authenticates the portable device by verifying the ID code stored in the built-in memory and the ID code in the portable device by utilizing the transmission and reception of such various signals. Then, if the portable device is a legitimate device, the vehic...
