FIG. 1A is a schematic diagram of a vehicle for explaining an example of a detection area of the moving object detection warning device according to the first embodiment, and FIG. 1B is a block diagram of the moving object detection warning device. It is an example. Note that, in each drawing according to the embodiment described below, the ratio between figures may be different from the actual ratio. Further, in FIG. 1B and FIG. 3 to be described later, main signals and information flows are indicated by arrows.

  As shown in FIG. 1A, the moving object detection warning device 1 is mounted on the vehicle 9 and warns at least toward the outside of the vehicle 9 when a moving object in the vehicle is detected after the driver leaves the vehicle 9. Is configured to do. In other words, the moving body detection warning device 1 suppresses dehydration and the like when an infant, an elderly person, a sick person, or the like who cannot open the door by himself and leave the vehicle 9 is left in the vehicle. This warns the people around the vehicle 9 that there are people.

  As shown in FIGS. 1A and 1B, the moving object detection warning device 1 detects a moving object as a first detection unit that detects a moving object in a detection area 95 in the vehicle where movement of the moving object is assumed. A driver detection unit 12 as a second detection unit for detecting that the driver has left the vehicle 9 by communication between the unit 10 and the portable device 8 carried by the driver, and at least toward the outside of the vehicle 9 The moving object detection unit 10 is controlled to start detection of the moving object after the warning unit 14 that issues a warning and the driver detecting unit 12 detects that the driver has left the vehicle 9, and the moving object is detected. In this case, a control unit 16 that controls the warning unit 14 so as to issue a warning toward the outside of the vehicle 9 is schematically configured.

(Configuration of the moving object detection unit 10)
The moving object detection unit 10 sets a detection area 95 as an area where a moving object such as a person or an animal can move in the vehicle, and detects whether or not a moving object exists in the detection area 95.

  As an example, the detection area 95 is an area surrounded by a dotted line in FIG. 1A, and is an area behind the passenger seat 91, the passenger seat 92, the rear passenger seat 93, and the rear seat 93. A luggage space 94 is included. The luggage space 94 is an area in which luggage or the like provided behind the rear seat 93 can be stored, such as a hatchback car. Further, the luggage space 94 can expand an area for storing luggage or the like by tilting the rear seat 93. Accordingly, since the infant or the like can enter the luggage space 94 from the rear seat 93 side, the luggage space 94 is included in the detection region 95.

  As an example, the moving body detection unit 10 is disposed in an interior light 96 disposed on the ceiling of the vehicle 9 as illustrated in FIG. The arrangement of the moving object detection unit 10 is not limited to the interior lamp 96, and may be any place where the moving object in the detection area 95 can be detected. Further, the number of moving object detection units 10 is not limited to one, and a plurality of moving object detection units 10 may be arranged in the detection region 95.

  The moving object detection unit 10 analyzes, for example, an object that detects a moving object based on reflection of electromagnetic waves or ultrasonic waves, an object that detects a moving object based on a temperature distribution in the detection area 95, or an image obtained by capturing the detection area 95 with a camera. For example, a device that detects a moving object can be used. As an example, the moving body detection unit 10 of the present embodiment is a moving body detection sensor using a microwave.

Motion detection unit 10 outputs, for example, the control unit 16 the result of detection of the moving object as moving object information S _1. This motion information S ₁ is, for example, information indicating the presence or absence of a moving object.

(Configuration of driver detection unit 12)
The driver detection unit 12 performs wireless communication with the portable device 8 carried by the driver, and determines whether the driver is away from the vehicle 9 based on the result of the wireless communication. The driver detection unit 12 based on the determination result to generate a driver information S _2, and outputs to the control unit 16.

  If the driver detection unit 12 communicates with the portable device 8 and determines that the portable device 8 is located outside the vehicle 9, the driver detection unit 12 determines that the driver has left the vehicle 9. For example, the driver can lock and unlock the door of the vehicle 9 and start the engine by carrying the portable device 8 registered in advance in the vehicle 9.

(Configuration of warning unit 14)
When the driver leaves the vehicle 9 and a moving object is detected in the vehicle, the warning unit 14 gives a warning toward the outside of the vehicle 9 and a warning toward the inside of the vehicle 9.

Warning unit 14 may, for example, based on the warning signal S ₃ output from the control unit 16, or flashes the headlights and direction indicator of the vehicle 9, toward and horn or pre-registered voice to the outside It is configured so that it can be output.

  Moreover, the warning part 14 displays the warning sentence and warning image as a warning on the display apparatus 97 mounted in the vehicle 9, for example. The display device 97 also functions as a display unit such as a navigation device. For example, the warning unit 14 may display a warning text and a warning image on a sub-display disposed in the vicinity of a head-up display, a speedometer, or the like.

Here motion detection alarm device 1 is configured such when the stop signal S ₄ is inputted, it stops the warning. The stop signal S _4, for example, may be outputted by the operation of the switch device disposed in the vehicle, it may be output by operation of the touch panel which is arranged to overlap the display device 97, display device 97 It may be output by operating a touch pad that is a remote device capable of operating the pointer displayed on the screen.

Microcomputer. In this ROM, for example, a program for operating the control unit 16 and a set time 160 are stored. For example, the RAM is used as a storage area for temporarily storing calculation results and the like. Moreover, the control part 16 has a means to measure time inside.

  The control unit 16 performs moving object detection with the driver leaving the vehicle 9 as a trigger. This moving body detection cannot be stopped by the driver or the like.

  In addition, the control unit 16 sets the warning unit 14 to warn outside the vehicle 9 when a moving object is detected after a predetermined time has elapsed after the driver is detected to have left the vehicle 9. Control.

  This set time 160 is the above-mentioned predetermined time. When it is determined that the driver has left the vehicle 9, the control unit 16 starts measuring time, and starts moving object detection after the measured time exceeds the set time 160. The moving body detection operation by the moving body detection unit 10 may be started after the vehicle 9 is turned on or when it is determined that the driver has left the vehicle 9. In this case, even if a moving object is detected, the warning is in a standby state until the set time 160 is exceeded.

The control unit 16, when the stop signal S ₄ is inputted, stops the warning to control the alarm unit 14. Furthermore, the control unit 16 stops the warning even when the driver carrying the portable device 8 returns to the vehicle.

  Below, operation | movement of the moving body detection warning apparatus 1 of this Embodiment is demonstrated according to the flowchart of FIG.

The control unit 16 confirms whether or not a moving object exists based on the moving object information S ₁ acquired from the moving object detection unit 10. Control unit 16 determines that the moving object is present in the detection region 95 (S3: Yes), and outputs to the warning section 14 generates a warning signal _{S 3.} Warning unit 14 performs a warning toward the inside and outside of the vehicle 9 based on the warning signal S ₃ obtained (S4).

Here, in step 3, while it is determined that there is no moving object (S < _b > 3: No), the controller 16 gets into the vehicle 9 based on the driver information S < _b > ₂ acquired from the driver detection unit 12. Check whether or not. When it determines with the driver | operator having boarded the vehicle 9 (S5: Yes), the control part 16 complete | finishes a moving body detection (S6).

The control unit 16, when the driver is determined to not boarded the vehicle 9 (S5: No), it proceeds to step 3, to check whether the moving body information S ₁ elements are present.

(Effects of the first embodiment)
The moving body detection warning device 1 according to the present embodiment can start moving body detection in the vehicle at an appropriate timing. Specifically, the moving body detection warning device 1 starts the moving body detection after the driver carrying the portable device 8 is separated from the vehicle by the driver detection unit 12, and thus starts based on the opening / closing of the door. As compared with the above, it is possible to suppress an unpleasant feeling that a warning is given even though an infant or the like is in the vehicle together with the driver.

  Since the moving object detection warning device 1 gives a warning when the moving object detection starts or when a moving object exists after the driver leaves the vehicle and the set time 160 elapses, the driver is expected to return in a short time. It is suppressed that a warning is given even if it leaves.

  The moving object detection warning device 1 includes the luggage space 94 in the detection area 95 for detecting the moving object, so that it can detect even when an infant enters the luggage space 94 as compared to the case where the luggage space is not included. A situation in which the vehicle is left in the vehicle for a long time can be suppressed with high accuracy.

  Since the moving object detection warning device 1 can detect a moving object with high accuracy, it is possible to suppress a situation in which an infant or the like is left in the vehicle for a long time to cause dehydration.

Motion detection warning device 1, it is possible to stop the warning by the stop signal S ₄ that is output from a switch located on the vehicle on the basis of the performed the operation, as compared with the case where there is no such switch for stopping The warning can be stopped when a warning is issued even if a person who can understand and stop the warning is on board.

  Since the moving body detection warning device 1 can also detect a third person who has entered the vehicle without permission, it can warn the intrusion and suppress acts such as theft. When the moving object detection warning device 1 has high crime prevention properties, it is preferable that a switch device or the like for stopping the warning is not arranged.

  Since the moving body detection warning device 1 cannot stop the moving body detection, the situation where an infant or the like is left in the vehicle for a long time by stopping the moving body detection is suppressed.
