Abstract

PROBLEM TO BE SOLVED: To prevent the occurrence of a theft regarding a parked vehicle by applying the constitution that sideview mirrors are formed to contain a camera for monitoring a view behind the vehicle in a status displaced to a service position, as well as for monitoring the cabin of the vehicle at a stowed position, and a means for detecting the physical change of the vehicle. SOLUTION: A camera 12 and a physical change detection means are built into sideview mirrors 11, and these sideview mirrors 11, when at service positions during the travel of a vehicle, turn into a rear view monitor mode and display the images of the rear views 21L and 21R of the vehicle on a monitor, thereby enabling a driver to confirm a condition behind the vehicle via the slight change of his/her line of sight. Also, the sideview mirrors 11 when at stowed positions during the parking of the vehicle, are turned into a vehicle inside monitor mode, and the physical change detection means detects the vibrations of the vehicle. At the same time, the camera 12 photographs cabin internal views 22L and 22R and displays the images thereof on the monitor. According to this construction, the occurrence of a theft regarding a parked vehicle can be prevented.

[0003]

However, in the above-mentioned vehicle anti-theft device, the camera is used only when parked, and in the vehicle rear view device, the camera is used only when running. Further, in the above-mentioned vehicle anti-theft device, the perpetrator can be specified at a later date by photographing and recording the perpetrator, but the vehicle is often already damaged.

An object of the present invention is to solve such a problem, and the camera can be commonly used for rearward monitoring while a vehicle such as an automobile is running and for preventing vehicle theft during parking. Another object of the present invention is to provide a vehicle antitheft device that can prevent damage to the vehicle by making the perpetrator aware that the vehicle is being monitored.

[0005]

According to a first aspect of the present invention, there is provided a door mirror, which is mounted on left and right doors of a vehicle such as an automobile, and which is rotatably displaced between a use position and a storage position. It is characterized in that it has a built-in camera for monitoring the rear of the vehicle when it is displaced to the use position and for monitoring the inside of the vehicle at the storage position, and means for detecting a physical change of the vehicle.

The invention according to claim 2 further comprises means for illuminating a photographing range of the camera by inputting an output signal of the physical change detecting means of the vehicle, and a monitor for displaying an image picked up by the camera. It is characterized by having.

The invention according to claim 3 is further provided with position information detecting means for the door mirror, and means for inputting an output signal of the detecting means to switch between a rear monitoring mode and a vehicle interior monitoring mode. And

According to the first aspect of the present invention, the camera can be used for rearward monitoring while traveling and for vehicle theft prevention during parking.

According to the second aspect of the present invention, when the physical change of the vehicle is detected, it is illuminated, and the inside of the vehicle is photographed by the camera to be displayed on the monitor. it can.

According to the third aspect of the invention, by automatically switching between the rearward monitoring mode and the vehicle interior monitoring mode based on the position information of the door mirror, it is possible to save the time and labor for switching the modes and to perform the reliable mode switching.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a vehicle antitheft device according to the present invention will be described with reference to the drawings. FIG. 1 shows a door mirror having built-in cameras mounted on the left and right doors of an automobile, 11 is a door mirror, 12 is a camera, and 13 is a lighting device. FIG. 2 shows the photographing range of the camera 12 at the use position and the storage position of the door mirror 11, and the rear side 21L and 21R of the automobile is the photographing range at the use position. In addition, at the storage position, the interiors 22L and 22R of the automobile are the photographing range.

FIG. 3 is a block diagram of the vehicle antitheft device, in which 12 is a camera, 13 is an illuminating device, 31 is a physical change detecting means of the automobile, and 32 is position information detecting means of the door mirror 11. Reference numeral 33 is a mode switching means for automatically switching to a rear monitoring mode when the result detected by the position information detecting means 32 of the door mirror is a use position, and to a vehicle interior monitoring mode when it is a storage position. Reference numeral 34 is a monitor, and 35 is a video recording device such as a video or image memory.

In the above structure, when the vehicle is traveling and the door mirror 11 is in the use position, the rear monitoring mode is set and the images of the rear 21L and 21R of the vehicle are displayed on the monitor 34 so that the driver can move the line of sight. You can check the back of the car with a little bit. When the vehicle is parked and the door mirror 11 is in the retracted position, the vehicle interior monitoring mode is set, and when the physical change detecting means 31 of the vehicle detects the physical change, for example, the vibration of the vehicle, the camera 12 turns on. 22L inside the car
And 22R are photographed and the images are displayed on the monitor 34. As a result, the threat of being monitored by the criminal can be given, and the theft can be abandoned. In addition, since theft often occurs at night, the lighting device 13
By illuminating the shooting direction of the camera 12 by
A clearer image can be obtained, and the intimidating effect is given to the criminal. Furthermore, by recording the image at this time in the image recording device 35, the situation at the time of theft can be confirmed later.

The storage operation of the door mirror 11 is performed manually or in conjunction with the operation of the key or the door lock. The position information detecting means 32 of the door mirror detects that the door mirror 11 is in the storage position, and the mode is output based on the output signal. Since the switching means 33 automatically switches to the automobile internal monitoring mode, the labor of mode switching can be saved and the mode can be reliably switched.

[0015]

According to the first aspect of the present invention,
The camera can be used for rearward monitoring while the vehicle such as an automobile is running, and can be used for preventing vehicle theft when parked, thus improving the efficiency of use of the camera.

According to the second aspect of the invention, when the physical change of the vehicle is detected, the illumination is performed, and the inside of the vehicle is photographed by the camera and displayed on the monitor, thereby exerting a threatening effect. Therefore, damage to the vehicle can be prevented.

According to the third aspect of the present invention, by automatically switching between the rearward monitoring mode and the vehicle interior monitoring mode based on the position information of the door mirror, it is possible to save the time and labor for mode switching. It is reliable and convenient.
