Description

Description
VEHICLE-MANAGEMENT SYSTEM
Technical Field
[1] The present invention relates to a vehicle management system, and more particularly to a vehicle management system for allowing post-management of various accidents occurring in a vehicle to be effectively conducted. Background Art
[2] In general, various devices are provided in a vehicle for the purpose of a driver's convenience and safety. In particular, a collision sensor, a proximity sensor, a camera, etc. are provided at the front side and/or rear side of a vehicle, so that a collision from the front or rear side during movement of the vehicle, or while the vehicle is parked or stopped, can be sensed through the collision sensor, and an approaching vehicle can be sensed and alarmed through the proximity sensor, whereby driver's safety from a collision or a rear end collision can be secured. In addition, burglary of the vehicle can be prevented in advance.
[3] Providing a camera on the rear side of the vehicle allows a driver to monitor a rear approaching vehicle or to conveniently back out while viewing the external area of the rear side through the camera.
[4] Recently, navigation systems have been provided so that a driver can drive a vehicle while recognizing a road state by receiving information regarding the traffic states for roads desired to be traveled from a GPS satellite.
[5] In addition, a front sensor using supersonic waves is mounted on a front bumper of a vehicle so as to detect the surface condition of a road on which the vehicle is traveling. The suspension (air spring) of the vehicle can be controlled on the basis of the detected result, thereby controlling impact applied to the body of the vehicle or the height of the vehicle. In this manner, it is possible to improve the driving quality of the vehicle and to prevent, in advance, an accident caused by a dangerous road.
[6] Like this, vehicles (automobiles) have occupied a position as daily necessities in modern society, and various convenient facilities for vehicles have been developed. However, vehicle -related accidents or events still frequently occur in proportion to the increase of the number of vehicles. For example, a non-forecastable traffic accident, such as a collision or a rear end collision, occurs during movement of a vehicle. Even in a dark underground parking lot, a collision accident or a case of burglary occurs after vehicles are parked.
[7] In a traffic accident during movement of a vehicle, the liability for the accident is examined on the basis of a statement of a driver or a witness. However, in many cases, subjective views may be introduced to such a statement, so that an amicable result cannot be made.
[8] When a case of burglary occurs in an unfrequented dark parking lot, it is difficult to secure evidence. When kidnapping using a vehicle or theft of a vehicle occurs, a lot of time may be required to find the related vehicle, or it may be difficult to judge the correct situation until the vehicle is found after the vehicle is stolen.
[9] Therefore, what is needed is to conduct various researches for minimizing losses concerning a traffic accident or a case of burglary or the like that occurs during movement of a vehicle or while a vehicle is parked, and for allowing the correct situation or evidence of such an accident or the like to be found, beyond the research for improving the convenience of vehicles. Disclosure of Invention Technical Problem
[10] Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the prior art, and the present invention is to provide a vehicle management system for allowing post-management for various accidents occurring in a vehicle to be effectively conducted. Technical Solution
[11] In order to accomplish the above-mentioned objects, there is provided a vehicle management system including: a speed sensing unit for detecting a traveling speed of the vehicle; a plurality of cameras for photographing the external sights of front side, rear side and opposite lateral side of the vehicle, respectively; a plurality of camera driving units; an image processing unit for processing images photographed by the cameras; an image outputting terminal for outputting the images processed by the image processing unit to a separate external display device; a plurality of storage units for backing up the images processed by the image processing unit; a key input unit for inputting commands for controlling the movement of the cameras; a key-inputted command display unit for displaying the commands inputted through the key-input unit; a camera condition outputting unit for presenting the conditions of the cameras; and a control unit for storing the images photographed by the cameras according to the traveling speed of the vehicle detected by the speed sensing unit to the storage units.
[12] In addition, the vehicle management system may further include a wireless transceiver device capable of conducting remote control in real time for informing the position of the vehicle, transmitting the image and voice of the driver of the vehicle, releasing door locking, and switching on or switching off the engine of the vehicle.
[13] Here, the vehicle management system may preferably include one or more of: a GPS
(Global Positioning System) transceiver unit for transmitting/receiving GPS signals indicative of the position of the vehicle; a user camera unit for photographing the user within the vehicle; a display device for displaying image signals outputted from the image outputting terminal; one or more power sources for supplying power to the vehicle management system; and a plurality of movement detection sensors for detecting movements within a predetermined in a state in which the engine of the vehicle is switched off, the movement detection sensors being provided on the front side, rear side, and opposite lateral sides of the vehicle.
[14] The power sources are preferably formed by one or more of a vehicle battery and a rechargeable battery charged during movement of the vehicle.
[15] The storage units are preferably formed by a digital video recorder (DVR), a memory card, and a black box.
[16] Each of the cameras is preferably implemented by a CCD (Charge Coupled Device) with more than one million pixels and illumination allowing night photographing, wherein the CCD is embedded in a rear view mirror case, which is preferably formed from a transparent material in the photographing direction.
[17] The control unit preferably controls the number of stored frames for photographed image data according to the traveling speed of the vehicle, and controls the photographing of an object approaching the vehicle within a predetermined range and the storage of photographed images when the vehicle is parked.
Advantageous Effects
[18] According to the present invention, the following effects can be obtained:
[19] i) Information indicative of various contents of an accident occurring during movement or parking of a vehicle can be obtained and stored, so that the accident can be effectively managed; [20] ii) It is possible to prevent the cause of an accident from becoming indistinct or getting complicated; and [21] iii) Information obtained by the inventive vehicle management system makes it possible to quickly analyze the cause of an accident, and can be used instead of a statement of a witness.

[31] The inventive vehicle management system 200 may further include one or more of: a
GPS (Global Positioning System) transceiver unit 20 for transmitting/receiving GPS signals indicative of the position of the vehicle; a user camera unit 50 for photographing the user within the vehicle; a display device for displaying image signals outputted from the image outputting terminal 70; first and second power sources for supplying power to the vehicle management system 200; and movement detection sensors 160 for detecting a movement within a predetermined in a state in which the vehicle is parked (switched off), the movement detection sensors being provided on the front side, rear side, and opposite lateral sides of the vehicle.
[32] If a movement is detected by any of the movement detection sensors 160, the control unit 170 renders a camera 30 directionally corresponding to the movement to photograph the object, the movement of which is detected, and stores photographed images in the first to third image storage units 80, 90 and 100.
[33] The first power source 140a may be formed by the vehicle battery, and the second power source 140b may be formed by a rechargeable battery. While the vehicle is being driven, the power required by the vehicle management system is supplied from the first power source 140a, and when the vehicle is switched off, the power of the second power source 140b charged during movement of the vehicle is used as the power of the vehicle management system.
[34] The first storage unit 80 may be formed by a digital video recorder (DVR), the second storage unit 90 may be formed by a memory card, and the third storage unit 100 may be formed by a backup-enabled black box.
[35] Here, a data storage device generally used for various digital electronic appliances, such as a PC, a PDA (Personal Digital Assistant), a digital camera, an MP3 player, etc., may be employed as the memory card. Preferably, a flash memory may be employed so that stored contents are not erased, even if the power source is turned off. In addition, a multi-card reader may be provided so that one or more of a smart card media, a CF (Compact Flash) memory, a memory stick, and a SD (Secure Digital) memory card can be employed. More preferably, a high-capacity memory card is provided, so that contents photographed over 1 to 7 days can be basically stored.
[36] A data-recorded PCB (Printed Circuit Board) can be used as the black box. The PCB is preferably covered by a molding or an insulation material for protecting the PCB from impact, moisture and heat, which can be applied through various field tests by those skilled in the art.
[37] FIG. 2 is a block diagram for describing cameras in the inventive vehicle management system in detail.
[38] The cameras 30 in the inventive vehicle management system 200 include first to n camera driving units (40a to 4On) for driving first to n cameras (30a to 30n) for photographing the front side, rear side, and opposite lateral sides of the vehicle, respectively.
[39] The first to n camera driving units (40a to 4On) control the movements of the first n cameras up and down and leftward and rightward under the control of the key input unit 120.
[40] At this time, the above-mentioned control can be made while viewing the image display device 110.
[41] In addition, each of the first to n camera driving units is preferably formed by a motor.
[42] FIG. 3 is a front view of the inventive vehicle management system.
[43] The front side of the inventive vehicle management system includes: a camera condition outputting unit 150 formed by light-emitting devices (e.g., LEDs) 150a to 150n indicating the operating conditions of the cameras, respectively; a key input unit 120 including a key for selecting vehicle's modes (automatic mode, traveling mode, parking mode, etc.) or a plurality of keys for searching data stored in the storage units 80, 90 and 100; a memory card installing/extracting unit 90a for installing or extracting the second storage unit 90; and an image outputting terminal 70 for outputting the images of the cameras 30 to the image display unit 110.
[44] FIGs. 4 and 5 are views showing the state of cameras on a rear view mirror in the inventive vehicle management system during traveling.
[45] The arrangement of the cameras on a rear view mirror in the inventive vehicle management system are formed by cameras provided within the rear view mirror case 180 for photographing the front side, rear side, and opposite lateral sides of the vehicle. FIG. 4 is a front view of the rear view mirror case 180, and FIG. 5 is a top plan view of FIG. 4. FIG. 6 is a side view of the rear view mirror case 180 in the folded state, and FIG. 7 is a top plan view of FIG. 6.
[46] For example, the camera 30a in FIGs. 4 and 5 photographs the external sight in the front side through a first lens 31a, the second camera 30b photographs the external sight in the rear side through a second lens 31b, and the third camera 30c photographs the external sight in the left side through a third lens 31c. As shown in the drawings, the cameras 30 are embedded in the rear view mirror case 180, which is preferably formed from a transparent material.
[47] If the rear view mirror case 180 is in the folded state as shown in FIGs. 6 and 7, the first camera 30a is arranged to photograph the external sight in the front side through the first camera driving unit 40a, the second camera 30b is arranged to photograph the external sight in the rear side through the second camera driving unit 40b, and the third camera 30c is arranged to photograph the external sight in the left side through the third camera driving unit 40c.
[48] In other words, if the rear mirror case 180 is folded when the vehicle is switched off at the time of parking, or folded by the key input unit 120, the positions of the cameras are automatically changed by the camera driving units 40.
[49] In addition, the user can conduct control for optimizing the position of each of the cameras through the key input unit 120 while viewing, through the image display device 110, the images which are currently captured by the cameras 30.
[50] In addition, the control unit 170 renders the capture images to be processed according to the traveling speed of the vehicle. For example, if the traveling speed of the vehicle sensed by the speed sensing unit 10 is high, the control unit 170 renders the image data to be stored in a high speed (by increasing the photographing speed of each of the camera per second), and if the traveling speed of the vehicle sensed by the speed sensing unit 10 is low, the control unit 170 renders the image data to be stored in a low speed (by decreasing the photographing speed of each of the camera per second).
[51] Here, the high speed range and the low speed range can be variously set through field tests or by a user's setting. For example, in high-speed traveling (for example, 60 km/ hour or more), 24 to 32 frames are photographed per second, and in low-speed traveling (for example, less than 60 km/hour), 1 to 24 frames are photographed per second.
[52] CCDs (solid state image sensors) with more than one million pixels and illumination allowing night photograph are preferably employed as the cameras.
[53] If the movement detection sensors 160 installed at various positions on the vehicle for detecting movements detect a movement in a parked state, the control unit 170 renders a camera 30 directionally corresponding to the detected movement to photograph an object approaching the vehicle within a predetermined range (for example, 2 to 4 m), and renders the photographed images to be stored in the first to third storage units 80, 90 and 100.
[54] When an accident of the vehicle is sensed, or the vehicle is stolen, the control unit transmits a GPS signal indicative of the current position of the vehicle through the GPS transceiver unit 20. Even if the vehicle is switched off, the control unit 170 receives power through the second power source 140b and periodically transmits the GPS signal indicative of the current position of the vehicle. In addition, if the driver camera unit 50 is a mobile communication terminal, the image and voice of the driver and the surrounding topography and scene can be easily recognized in real time.
[55] Like this, the second power source can supply power to the movement detection sensors 180, the cameras 30, the image processing unit 60, and the first to third storage units as described above, even if the vehicle is parked, so that the detection of movement, photographing, and the processing and storage of photographed images can be executed. Industrial Applicability
[56] Although preferred embodiments of the present invention have been described for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims. Therefore, the present invention is not limited to the embodiments described above.
