That is, when the mobile communication terminal 3 is placed on the installation base, it is possible to perform communication between the mobile communication terminal 3 and the NFC communication device 12 by the NFC communication method from the vehicle interior side.

As is well known, the window glass of the triangular window 101 can transmit radio waves. In other words, the portable communication terminal 3 and the NFC communication device 12 communicate with each other by the NFC communication method from the outside of the passenger compartment by bringing the portable communication terminal 3 close to the NFC antenna 15 provided in the triangular window 101. It is possible.

The lock sensor 21 is, for example, a touch sensor provided near the door handle of the vehicle door on the driver's seat side, detects contact of the user's body part with the lock sensor 21, and outputs a detection signal to the authentication ECU 11. To do. In addition, a user here means the passenger | crew of the own vehicle containing a driver | operator.

The unlock sensor 22 is, for example, a touch sensor provided on a door handle of a vehicle door on the driver's seat side, detects contact of the user's body part with the unlock sensor 22, and sends a detection signal to the authentication ECU 11. Output.

The engine switch 23 is provided, for example, on the driver seat side of the console panel in the passenger compartment, detects an operation (for example, a push operation) on the engine switch 23 by the driver, and outputs a detection signal to the authentication ECU 11.

The body ECU 24 is connected to the authentication ECU 11 via a common bus communication path 27. When the body ECU 24 is set to the unlocking standby state described later by the authentication ECU 11, when the unlock signal is received from the authentication ECU 11, the body ECU 24 operates a door opening / closing mechanism (not shown) to automatically unlock the vehicle door.

The power supply switching device 26 is a device that switches between supply and stop of power to the NFC communication device 12. The power supply switching device 26 supplies power to the NFC communication device 12 when receiving a wake-up signal described later from the authentication ECU 11, and supplies power to the NFC communication device 12 when receiving a sleep signal described later from the authentication ECU 11. Stop supplying. Hereinafter, a state in which power is supplied to the NFC communication device 12 is referred to as a wake-up state, and a state in which power is not supplied is referred to as a sleep state.

The authentication ECU 11 is an electronic control device including a microcomputer having a CPU 111, a ROM 112, a RAM 113, and the like. An ID code of a registration key is recorded in the ROM 112 of the authentication ECU 11. The authentication ECU 11 executes processing for performing various controls based on communication with the mobile communication terminal 3 in accordance with a program recorded in the ROM 112. For example, the authentication ECU 11 sets the body ECU 24 in the lock standby state when receiving the detection signal from the lock sensor 21, or sets the body ECU 24 in the unlock standby state when receiving the detection signal from the unlock sensor 22. When the detection signal is received from the engine switch 23, a process of setting the engine ECU 25 to the start standby state is executed. Further, in parallel with these processes, the authentication ECU 11 executes a vehicle control process for locking and unlocking the vehicle door and starting the engine for the vehicle 1.

[2. processing]
Next, the vehicle control process which CPU111 of authentication ECU11 performs is demonstrated using the flowchart of FIG. The vehicle control process is repeatedly executed while power is supplied to the authentication ECU 11.

First, in S (step) 110, the authentication ECU 11 determines whether or not the engine is stopped. Specifically, the authentication ECU 11 determines that the engine is stopped when the drive signal is not output from the engine ECU 25. The authentication ECU 11 shifts the process to S165 when the engine is stopped, and shifts the process to S115 when the engine is not stopped.

In S115, the authentication ECU 11 determines whether communication using the BT communication method is being performed with the mobile communication terminal 3. Specifically, for example, when the authentication ID code received from the mobile communication terminal 3 by the BT communication device 16 matches the ID code of the registration key, the authentication ECU 11 establishes authentication for the mobile communication terminal 3. Therefore, it is determined that communication using the BT communication method is being performed with the mobile communication terminal 3. The authentication ECU 11 shifts the process to S165 when communication by the BT communication method is being executed, and shifts the process to S120 when communication by the BT communication method is not being executed.

In S120, the authentication ECU 11 determines whether any one of the lock sensor 21, the unlock sensor 22, and the engine switch 23 has detected a user instruction for the host vehicle. Specifically, the authentication ECU 11 determines that the user's instruction for the host vehicle has been detected when a detection signal is output from any one of the lock sensor 21, the unlock sensor 22, and the engine switch 23. The authentication ECU 11 shifts the process to S165 when the user's instruction for the host vehicle is not detected, and shifts the process to S125 when the user's instruction for the host vehicle is detected.

In S125, the authentication ECU 11 puts the NFC communication device 12 into a wake-up state. Specifically, the authentication ECU 11 outputs a wake-up signal to the power supply switching device 26 to cause the power supply switching device 26 to supply power to the authentication ECU 11 and activate the NFC communication device 12.

Subsequently, in S130, the authentication ECU 11 determines whether authentication for the mobile communication terminal 3 is established. Specifically, the authentication ECU 11 determines that the authentication is established when the authentication ID code included in the data output from the NFC communication device 12 matches the ID code of the registration key. The authentication ECU 11 shifts the process to S140 when the authentication is established, and shifts the process to S135 when the authentication is not established.

In S135, the authentication ECU 11 determines whether or not a predetermined time has elapsed. If the predetermined period has elapsed, the authentication ECU 11 shifts the process to S165, and if the predetermined period has not elapsed, shifts the process to S130. .

Authenticating ECU 11 determines whether or not the user's instruction for the host vehicle detected in S120 is an engine start in S140, which proceeds to the case where authentication has been established (S130; YES). Specifically, when the detection signal is output from the engine switch 23, the authentication ECU 11 determines that the user's instruction for the host vehicle is an engine start. The authentication ECU 11 shifts the process to S150 when the instruction is not an engine start, and shifts the process to S145 when the instruction is an engine start.

In S145, the authentication ECU 11 performs output for engine start control. Specifically, the authentication ECU 11 outputs a start signal to the engine ECU 25 set in the start standby state, and causes the engine ECU 25 to perform engine start control.

In S150, where the operation instruction is not an engine start (S140; NO), the authentication ECU 11 determines whether or not the user's instruction for the host vehicle detected in S120 is a locking instruction. Specifically, the authentication ECU 11 determines that the instruction is a locking instruction when a detection signal is detected from the lock sensor 21. The authentication ECU 11 shifts the process to S160 when the instruction is not a locking instruction, and shifts the process to S155 when the instruction is a locking instruction.

In S155, the authentication ECU 11 performs output for locking control. Specifically, the authentication ECU 11 outputs a locking signal to the body ECU 24 and causes the body ECU 24 to execute locking control.

In S160, the process proceeds to a case where the instruction is not a locking instruction (S150; NO), the authentication ECU 11 performs an output for unlocking control. Specifically, the authentication ECU 11 outputs an unlock signal to the body ECU 24 and causes the body ECU 24 to execute unlock control.

In S165, the authentication ECU 11 puts the NFC communication device 12 into a sleep state. Specifically, the authentication ECU 11 causes the power supply switching device 26 to stop supplying power to the authentication ECU 11 by outputting a sleep signal to the power supply switching device 26. After outputting the sleep signal, the authentication ECU 11 moves the process to S110. When the engine is stopped (S110; NO), when BT communication is being executed (S115; YES), when the user's instruction for the own vehicle is not detected (S120; NO), the user's instruction for the own vehicle When the authentication of the mobile communication terminal 3 is not established even after a predetermined period of time has elapsed after the detection of the vehicle (S135; YES), an output corresponding to the user's instruction for the host vehicle is performed (S145, S155, After S160), the process proceeds to this step, and the NFC communication device 12 is set in the sleep state.

Accordingly, for example, if the user holds the mobile communication terminal 3 over the NFC antenna 15 from the outside of the vehicle through the door glass of the triangular window 101 and operates the lock sensor 21 or the unlock sensor 22, that is, a part of the human body such as a hand is moved. If the mobile communication terminal 3 is authenticated, the vehicle door is locked or unlocked.

In addition, if the user installs the mobile communication terminal 3 on the installation base in the vehicle interior and operates the engine switch 23, the engine is started when the authentication for the mobile communication terminal 3 is established.
