Hereinafter, the best mode for carrying out the present invention will be described with reference to the accompanying drawings.
(First embodiment)
FIG. 1 is a block diagram showing a system configuration of a parking assistance system according to the first embodiment of the present invention. The parking assistance system 1 according to the present embodiment is configured around a parking assistance ECU (Electronic Control Unit) 2. The parking assistance ECU 2 performs parking assistance (IPA) control for automatically guiding the vehicle to a parking target position in a facility (garage or the like) registered in advance (FIG. 2).

  The parking assist ECU 2, a steering ECU 6, a brake ECU 7, an engine ECU 8, and an authentication ECU 10, which will be described later, are microcomputers including a CPU, a ROM, a RAM, an interface circuit, and the like connected to each other via a bus. The ROM stores a control program for executing the CPU. The ECUs 6, 7, 8, and 10 are connected to each other via a network such as a vehicle LAN (Local Area Network) 9 and can transmit and receive bidirectional data.

  A steering angle sensor 3 that detects the steering angle of the steering wheel and a vehicle speed sensor 4 that detects the speed of the vehicle are connected to the parking assist ECU 2 via a bus. As the vehicle speed sensor 3, for example, a magnetic or optical encoder provided on a rotating shaft of a wheel is used. The vehicle speed sensor 3 generates a pulse signal at a cycle corresponding to the rotational speed of the wheel.

  A monitor camera 5 disposed at the rear of the vehicle is connected to the parking assist ECU 2. Here, the monitor camera 5 is disposed at the rear of the vehicle, but can be attached at any position as long as the rear of the vehicle can be photographed.

  The monitor camera 5 is a CCD or CMOS camera that captures a landscape in a predetermined angle region at the rear and side of the vehicle. The monitor camera 5 transmits the captured image to the parking assist ECU 2. The parking assistance ECU 2 performs parking assistance control based on the captured image transmitted from the monitor camera 5.

  The parking assist ECU 2 performs vehicle braking control based on an automatic steering means 6 such as an operation ECU that performs steering control of the vehicle based on a control signal from the parking assist ECU 2 and a control signal from the parking assist ECU 2. An automatic braking means 7 such as a brake ECU is connected via a vehicle LAN 9. Furthermore, an automatic driving means 8 such as an engine ECU for controlling the driving of the vehicle based on a control signal from the parking assistance ECU 2 is connected to the parking assistance ECU 2 via a vehicle LAN 9.

  For example, the steering ECU 6 controls the steering device 6a based on a control signal from the parking assist ECU 2 and performs steering control when the vehicle is parked. For example, the brake ECU 7 controls the brake device 7a based on a control signal from the parking assist ECU 2 and performs braking control when the vehicle is parked. For example, the engine ECU 8 controls the engine 8a based on a control signal from the parking assist ECU 2 and performs drive control when the vehicle is parked.

  The parking assistance switch 13 is provided in the vehicle interior and outputs an ON signal to the parking assistance ECU 2 by a user's switch operation. For example, the parking assistance ECU 2 starts parking assistance control based on an ON signal from the parking assistance switch 13. The parking assistance ECU 2 may start the parking assistance control when it receives the ON signal from the parking switch 13 and determines that the shift lever is in the back position.

  The parking assist ECU 2 controls the steering ECU 6, the brake ECU 7, and the engine ECU 8 so as to guide the vehicle to the parking target position based on the set parking target position and the captured image around the vehicle captured by the monitor camera 5. A control signal is transmitted. The parking target position is input and set by the driver via an input device such as a touch panel, for example.

  An authentication ECU 10 that performs authentication such as biometric authentication for the driver of the vehicle is connected to the parking assistance ECU 2 via the vehicle LAN 9. For example, the authentication ECU 10 is connected to a camera 11 that is attached to a rearview mirror, a windshield, or the like in the passenger compartment and photographs the driver's face. The camera 11 can be attached to any position as long as the driver's face can be photographed. The authentication ECU 10 performs biometric authentication by comparing image information relating to the driver's face registered in advance with an image of the driver's face taken by the camera 11.

  For example, the authentication ECU 10 determines that the authentication result is normal when the image information of the driver's face registered in advance matches the image of the driver's face taken by the camera 11. On the other hand, if the image information of the driver's face registered in advance and the image of the driver's face taken by the camera 11 do not match, the authentication ECU 10 determines that the authentication result is abnormal.

  The authentication ECU 10 transmits these authentication results to the parking assistance ECU 2 via the vehicle LAN 9. The parking assist ECU 2 holds the authentication result received from the authentication ECU 10.

  The authentication ECU 10 performs biometric authentication based on the driver's face image. However, the authentication ECU 10 may perform biometric authentication based on the driver's fingerprint or vein pattern. Applicable.

  Further, when a smart key is used as a vehicle key, for example, the driver may be authenticated by the smart key. Here, the smart key is a key having a function of automatically verifying an ID code and performing authentication by two-way communication between the key itself and the vehicle.

  The parking support ECU 2 is connected to a transmission / reception device 12 that transmits / receives data to / from a communication device 24 described later via a communication network 14. The communication network 14 includes, for example, a general telephone network, a mobile telephone network, the Internet, and the mobile telephone network includes a communication base station, an information center that functions as a server, and the like. Shall.

  The facility 20 registered in advance is provided with a door 21 such as an electric shutter that prevents a third person (for example, other than the registered person) from entering the facility 20. For example, the door 21 is normally in a closed state, and is opened when a registered vehicle enters.

  The door 21 is provided with an actuator 22 such as an electric motor that opens and closes the door 21. The actuator 22 is connected to a control device 23 that controls the opening and closing of the door 21 by controlling the driving of the actuator 22. The control device 23 is connected to a communication device 24 that transmits and receives data to and from the vehicle transmission / reception device 12.

  For example, the parking assist ECU 2 transmits an open signal for opening the door 21 to the control device 23 via the transmission / reception device 12 and the communication device 24. When receiving an open signal from the parking assist ECU 2, the control device 23 controls the actuator 22 to open the door 21. Thereby, the registered user can enter the facility 20.

  In addition, the parking assist ECU 2 transmits the authentication result received from the authentication ECU 10 to the control device 23 via the transmission / reception device 12, the communication device 24, and the communication network 14. When the control device 23 determines that the authentication result transmitted by the parking assist ECU 2 is normal, the control device 23 controls the actuator 22 to open the door 21. In this case, the registered driver's vehicle is determined to be a legitimate vehicle, enters the facility 20, and can be parked at the parking target position.

  On the other hand, when determining that the authentication result transmitted by the parking assist ECU 2 is abnormal, the control device 23 controls the actuator 22 to maintain the door 21 in the closed state. In this case, the driver's vehicle is determined not to be a legitimate vehicle, and cannot enter the facility 20.

  By the way, when parking support control is performed, a predetermined place in a facility (for example, a garage at home) 20 in which a door (for example, a shutter) 21 is closed may be set as a parking target position. In this case, conventionally, the driver needs to give a control instruction to the control device so that the shutter is opened, and thereafter, parking assistance control needs to be started by the parking assistance switch. For this reason, there is a risk of impairing the convenience of the driver.

  Therefore, in the parking assistance system 1 according to the present embodiment, the parking assistance ECU 2 starts parking assistance control based on the ON signal from the parking assistance switch 13. At this time, the parking assist ECU 2 transmits an authentication result by the authentication ECU 10 to the control device 23. The control device 23 opens the door 21 based on the authentication result transmitted from the parking assist ECU 2. Therefore, the driver does not separately instruct the control device 23 to open the door 21, and only operates the parking support switch 13 while opening the door 21 of the facility 20. The vehicle can be parked at the parking target position in 20.

  Next, the control processing flow of the parking assistance system 1 according to the first embodiment will be described. FIG. 3 is a flowchart illustrating an example of a control processing flow of the parking support system 1 according to the first embodiment. The control flow shown in FIG. 3 is repeatedly executed every predetermined minute time.

  When the driver gets on the vehicle (S100), the authentication ECU 10 compares the image of the driver's face registered in advance with the photographed image of the driver's face taken by the camera 11, and performs authentication ( S110).

  At this time, authentication ECU10 transmits an authentication result with respect to parking assistance ECU2, and parking assistance ECU2 hold | maintains the received authentication result (S120).

  When the parking assistance switch 13 is turned on by the driver, the parking assistance switch 13 outputs an on signal to the parking assistance ECU 2. When the parking assistance ECU 2 receives the ON signal from the parking assistance switch 13, the parking assistance ECU 2 starts parking assistance control (S130). At this time, parking assistance ECU2 transmits the authentication result received from authentication ECU10 with respect to the control apparatus 23 via the transmission / reception apparatus 12, the communication network 14, and the communication apparatus 24 (S140).

  Based on the authentication result received from the parking assist ECU 2, the control device 23 determines whether or not the driver's vehicle is a registered vehicle (normal) (S150).

  When the control device 23 determines that the driver's vehicle is a registered vehicle (normal) (Yes in S150), the control device 23 controls the actuator 22 to open the door 21 (S160). As a result, the vehicle enters the facility 20 and can park at the parking target position (S170).

  On the other hand, when the control device 23 determines that the driver's vehicle is not a registered vehicle (abnormal) (No in S150), the control device 23 controls the actuator 22 to maintain the door 21 in the closed state (S180). . Thereby, since it is possible to prevent an unregistered vehicle from entering the facility 20, the crime prevention property is improved.

  As described above, in the parking assistance system 1 according to the first embodiment, the parking assistance ECU 2 starts the parking assistance control based on the ON signal from the parking assistance switch 13. At this time, the parking assist ECU 2 transmits an authentication result by the authentication ECU 10 to the control device 23. The control device 23 opens the door 21 based on the authentication result transmitted from the parking assist ECU 2. Therefore, the driver parks the vehicle while opening the door 21 of the facility 20 only by operating the parking assist switch 13 without separately instructing the control device 23 to open the door 21. The support control can be started and the vehicle can be easily parked at the parking target position in the facility 20. In addition, since the door 21 is made into an open state based on the authentication result of a vehicle, crime prevention property is maintained reliably. That is, it is possible to improve the convenience for the driver while reliably maintaining crime prevention.

  Next, a modification of the parking support system 1 according to the first embodiment will be described.

  In the above embodiment, the parking assist ECU 2 sends a control signal to the control device 23 of the facility 20 so that the door 21 is opened based on the authentication result from the authentication ECU 10 at the start of the parking assist control. You may make it transmit.

Specifically, when receiving an ON signal from the parking assistance switch 13, the parking assistance ECU 2 determines whether or not the authentication result from the authentication ECU 10 is normal. When it is determined that the authentication result is normal, the parking assist ECU 2 transmits a control signal to the control device 23 via the transmission / reception device 12, the communication network 14, and the communication device 24. When receiving the control signal from the parking assist ECU 2, the control device 23 controls the actuator 22 to open the door 21.
