Description

  The present invention relates to a communication system mounted on a vehicle, for example.

  There is known a function of an automobile that enables locking or unlocking of a vehicle door without using a mechanical key, and further enabling starting of the vehicle. This function is also called “Smart Entry & Start System”. For example, mutual communication is performed between the in-vehicle device and the portable device. The in-vehicle device transmits a request signal. The request signal may be transmitted in an LF (Low Frequency) band. The portable device that has received the request signal transmits a response signal in response to the request signal. The portable device functions based on the response signal. The response signal may be transmitted in an RF (Radio Frequency) band.

  In addition, a function of locking or unlocking a door of a vehicle by operating a portable device is known. This function is also called “wireless door lock” or “keyless entry”.

  When the automobile functions so as to lock or unlock the door of the vehicle, communication using radio waves is performed between the in-vehicle device and the portable device. In the wireless power feeding technology, radio wave communication is performed between the power receiving side and the power transmitting side.

  Although communication using radio waves is increasing, consideration is given to ensuring that radio waves do not affect the human body within the appropriate range of use. However, some people who wear medical devices such as pacemakers (hereinafter referred to as “pacemakers”) need to be reassured because some people are concerned about the effects of radio waves. At present, attention is given to pacemaker wearers by the Owner ’s Manual (OM). Furthermore, consideration is given to giving a sense of security by performing an operation for stopping communication using radio waves and an operation for functioning without using communication using radio waves.

  There is known a technique that enables switching between valid and invalid functions such as locking or unlocking a door of a vehicle without providing a dedicated cancel switch (see, for example, Patent Document 1).

  Also, there is known a wireless power feeding technology capable of charging electric power by stopping at a predetermined charging spot for an electric vehicle (EV) using an electric motor as a power source.
