The on-vehicle device includes a reception part for receiving the driving request signal from the portable device, and a control unit for performing control to execute a predetermined operation to the vehicle according to the driving request signal.

Description

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

  A motor vehicle function is known that allows the door of a vehicle to be locked or unlocked without the use of a mechanical key, as well as to start the vehicle.

  For example, mutual communication is performed between the vehicle-side unit and the portable device. The vehicle side unit transmits a request signal. The portable device that has received the request signal transmits a response signal in response to the request signal. The vehicle side unit functions based on the response signal.

  Further, there is known a vehicular refueling port cover opening device that can easily open a refueling port according to the will of the occupant (see, for example, Patent Document 1).

  For example, when the vehicle is put into a gas station or the like and fueled, the owner of the vehicle is determined based on the identification information transmitted from the smart key. When a touch sensor provided in the fuel filler is turned on by a passenger such as an occupant or a gas station clerk, the filler opening / closing actuator is driven to automatically open the filler cover. When the refueling is finished and the occupant or the gas station clerk leaves the refueling port, the distance sensor detects this, and the refueling port opening / closing actuator is driven to automatically close the refueling port cover.

  In addition to using the rotational force of the engine directly as power, there is known a hybrid vehicle that is used to turn a generator.

  An electric vehicle (EV) using an electric motor as a power source is also known.

  There is also known a hybrid vehicle in which a plug is inserted into a socket attached to the vehicle and can be directly charged from an external power source. This type of hybrid vehicle is called a PHV (Plug-in Hybrid Vehicle) or PHEV (Plug-in Hybrid Electric Vehicle).

JP 2009-67277 A

  A charging lid is mounted on the EV or PHV. By connecting a charging cable to the charging lid, it can be directly charged from an external power source.

  Since EV and PHV have a short cruising distance compared to automobiles running on gasoline, it is assumed that EV and PHV will be charged more frequently. Therefore, in EV and PHV, it is desirable that the charging lid can be locked or unlocked in synchronization with the control of locking or unlocking the door by radio waves from the portable device.

  However, like the fuel lid, the charging lid does not have a lock control mechanism. The charging lid is opened by operating a lever for opening the lid of the charging lid. A lever for opening the charging lid is provided in the passenger compartment.

  Consider a control for locking or unlocking the lid of the charging lid in synchronization with the control for locking or unlocking the door by radio waves from the portable device. For example, in the vicinity of the charging lid, a switch for turning on a function for detecting a signal for requesting locking or unlocking of the charging lid from the portable device is provided in the in-vehicle device. When the switch is pressed, radio waves are transmitted from a transmitter mounted near the door.

  However, the communication area of the transmitter is formed around the transmitter. For this reason, when the position of the charging lid deviates from the communication area, the transmitter and the portable device located in the vicinity of the charging lid may not be able to communicate with each other. For example, the position where the charging lid is mounted is not specified. For this reason, depending on the position where the charging lid is mounted, it is assumed that the transmitter and the portable device located near the charging lid cannot communicate with each other.

  Even if you try to devise the antenna so that it can communicate with each other between the transmitter and the portable device located near the charging lid, the antenna may not be placed due to the influence of the metal part of the outer plate of the vehicle .

  By increasing the output of radio waves from the transmitter, the range of radio waves can be expanded. However, since the upper limit of the radio wave output value is stipulated by the laws of each country, the radio wave output cannot be designed freely.

  The present invention has been made in view of the above points, and has an object of causing a vehicle-mounted device to execute a predetermined operation by a portable device even when communication with the vehicle-mounted device is not possible. To do.
