  The BT communication unit 24 has a BT antenna, and transmits a signal (information) using a 2.4 GHz band radio wave to the in-vehicle device 1 via the BT antenna and uses a 2.4 GHz band radio wave. A signal transmitted from the in-vehicle device 1 is received via the BT antenna. The signal transmitted from the BT communication unit 24 is not as wide as the signal transmitted from the UHF transmission unit 23. The BT communication unit 24 is connected to the control unit 21 and transmits information output from the control unit 21 from the BT antenna, and outputs information received by the BT antenna to the control unit 21. Specifically, the BT communication unit 24 acquires the collected data by receiving the collected data transmitted from the BT communication unit 19 of the in-vehicle device 1. Therefore, the BT communication unit 24 includes the driving state information acquisition unit, the lighting / light-off state information acquisition unit, the instantaneous fuel consumption information acquisition unit, the instantaneous fuel consumption information acquisition unit, the position information acquisition unit, the travel distance information acquisition unit, and It functions as fuel consumption information acquisition means.

  The memory | storage part 25 is comprised by the memory which can rewrite the content electrically, and memorize | stores various information. The storage unit 25 stores the collected data received from the BT communication unit 24 by the control unit 21. Therefore, the storage unit 25 functions as a storage unit of claims.

  Further, in the control unit 21, when the collected data is transmitted from the in-vehicle device 1 by the transfer process, the order in which the collected data is stored in the storage unit 25 is stored so that the control unit 21 can determine later. In addition, in the control part 21, when collection data are transmitted from the vehicle-mounted apparatus 1 sequentially, these collection data will be stored in the memory | storage part 25 sequentially, and several collection data are stored in the memory | storage part 25. FIG. Will be stored.

  The push switches 26 and 27 are switches for mainly using the remote keyless entry function. When the push switch 26 is operated by one push, the vehicle door is locked. When the push switch 27 is operated by one push, the vehicle door is unlocked.

  For example, a touch switch or a mechanical switch integrated with the display 30 is used as the operation input unit 28, and operation instructions for various functions are given to the control unit 21 by a switch operation. Details of operation instructions for various functions performed by the operation input unit 28 will be described later.

  Further, the control unit 21 performs information display processing for causing the display 30 to display a display based on the collected data stored in the storage unit 25. Therefore, the control unit 21 and the display device 30 function as display means in the claims. The information display process will be described in detail later.

  Next, an outline of the smart entry function for unlocking the vehicle door according to the result of code verification using wireless communication between the in-vehicle device 1 and the portable device 2 will be described. In addition, about the process in each part of the vehicle-mounted apparatus 1 and the portable device 2 in a smart entry function, what is necessary is just to be performed like the technique disclosed by patent document 2 and patent document 3, for example.

  Each part of the in-vehicle device 1 operates under the control of the control unit 11, and under the control, the LF transmission unit 12 periodically transmits a so-called request signal for requesting transmission of a response signal. Each unit of the portable device 2 operates under the control of the control unit 21. When the portable device 2 enters the wireless communication area in which the request signal from the LF transmission unit 12 can be received, the request signal is transferred to the LF. The receiving unit 22 receives it.

  Note that wireless communication using radio waves in the LF band is performed between the LF transmitter 12 and the LF receiver 22. In order to limit the communication area between the in-vehicle device 1 and the portable device 2 to the periphery of the vehicle C, radio waves in the LF band are used for transmission / reception of request signals. Specifically, by transmitting signals from the door antenna 15a, the indoor antenna 15b, the back door outside antenna 15c, and the like, the communication area can be limited to the vicinity of the vehicle door, the vehicle interior, and the vicinity of the trunk. Thereby, possibility that the portable device 2 will receive the request signal from the vehicle-mounted apparatus 1 of another vehicle can be made low, for example.

  When the LF receiver 22 receives a request signal from the in-vehicle device 1, the UHF transmitter 23 transmits a response signal including a code unique to the vehicle C corresponding to the portable device 2. Then, in the in-vehicle device 1, the UHF receiving unit 13 receives the response signal transmitted from the portable device 2.

  Note that wireless communication using a radio wave in the UHF band is performed between the UHF receiver 13 and the UHF transmitter 23. The reason for using UHF band radio waves for the transmission / reception of the response signal is that the communication distance can be obtained even if the output level of the signal transmitted from the portable device 2 is weak, and the response signal is more reliably transmitted to the in-vehicle device 1 side. This is because it can be done.

  When the UHF receiving unit 13 receives the response signal transmitted from the portable device 2, the control unit 11 of the in-vehicle device 1 matches the code included in the response signal with the code stored in the control unit 11. The vehicle door is unlocked if it matches.

  In addition, after unlocking the vehicle door, known control in this type of vehicle system is executed. For example, when it is detected that a person has touched the door knob with a signal from a touch sensor (not shown) provided on the door knob outside the driver's door in the unlocked state, the control unit 11 goes to the door control system. An unlock signal is output, and as a result, a door lock motor (not shown) is driven and all vehicle doors are unlocked. In addition to this, various controls are performed such that the engine is allowed to start, but these controls themselves are matters that are not directly related to the main part of the present invention. Description is omitted.

  Subsequently, an information display process in the portable device 2 will be described. In the information display process, triggered by receiving a predetermined operation input from the user, the collected data stored in the storage unit 25 is read, and a display screen including a table and a graph is created based on the read collected data.

  For example, as an example of the information display process, the travel distance in the travel section and the average fuel consumption in the travel section are shown based on the trip meter value information and the fuel consumption information stored in the storage unit 25. A display screen as shown in FIG. 3 including a table is created and displayed on the display 30. In addition, what is necessary is just to set it as the structure which the control part 21 calculates | requires about the average fuel consumption by dividing the travel distance which the information of the value of a trip meter shows by the fuel consumption which fuel consumption information shows. Therefore, the control unit 21 also functions as an average fuel consumption calculating unit.
