Description

  The present invention relates to a kind of driving safety distance display method, and in particular, a driving safety distance display method for performing a preventive advance display and warning of a deviation situation on a roadway. It relates to a method for warning and ensuring driving safety.

  The most important thing for the deployment on the vehicle is safety. In recent years, the technology of image recognition and wireless detection has matured day by day, and many technologies have already been applied for vehicle safety. In response to market demands, functions such as examination of the distance between cars and warnings of roadway deviations have been developed and developed.

  There are two types of warning systems for current roadway deviations, one of which is a photo sensor installed near the front wheels below the vehicle to detect color changes near the wheels and display color on the display unit. When the color changes from black to white or yellow, it is determined that the road is shifted. Such a method is low in cost, but is liable to malfunction.

  The other type is to mount an imaging lens in front of the vehicle, usually at a high position inside the windshield glass, and take a picture of the scenery in front of the vehicle. The roadway line in the video is extracted, and the deviation amount of the roadway line is determined. When the deviation of the roadway line is set, the roadway deviation is determined. Such a method is expensive, but has a low probability of malfunction.

  There are also two types of inter-vehicle distance warning systems with the preceding vehicle, one of which uses a high-frequency millimeter wave radar (30 GHz to 300 GHz) or a laser radar to determine the inter-vehicle distance with the preceding vehicle. . Although the weather resistance and the expression of distance are both excellent, the cost is high and it is not possible to recognize whether the vehicle is on the same roadway or on the roadside fence, so that malfunction is likely to occur.

  The other is a method using video recognition, which usually captures an object in front with a fixed-angle imaging lens and extracts a direct vehicle object, which converts the elevation angle of the video with respect to the imaging lens into a distance and its cost. Although it is low and can use the same imaging lens as the roadway deviation warning system, the weather resistance is inferior. For example, factors such as dark night, heavy fog, and heavy rain can all affect the judgment of the vehicle ahead.

  The above-mentioned front inter-vehicle distance safety warning system using radar waves is usually attached to a high-priced vehicle, and a part of the warning system further works in conjunction with an actuator system to assist braking by activating a braking device when necessary. The forward vehicle safety warning system is expensive and has many parts involved, so it cannot be installed on a typical priced vehicle, and it is even more difficult for the vehicle owner to install it after purchasing the vehicle.

  Among high-level safety warning systems currently on the market, high-level products drive the vehicle braking and actuate system after determining the distance to the vehicle ahead, and adjust the vehicle speed based on the distance determination ahead. Thus, the front inter-vehicle distance is appropriately maintained. For low-level products, the front-to-front distance is displayed on the screen after the front-to-front distance is determined, and such distance data is not intuitive to the driver, which is very helpful to the driver. Must not. Another type of low-level product can generate an image or sound warning if the front-to-front distance is too short, but the driver cannot get a sufficient message before the warning to maintain a safe inter-vehicle distance.

  Traditional roadway deviation warning devices do not warn when no roadway is detected, i.e., when the vehicle does not shift on the roadway. Similarly, the front inter-vehicle distance safety warning device cannot detect when the front vehicle is detected, that is, if the inter-vehicle distance is not too short, and when such a situation is encountered, installation of such a safety device In addition to not being able to enhance the safety of the driver, on the other hand, it is easy for the driver to misunderstand that it is safe and to distract attention.

  In order to solve the above-mentioned drawbacks of using the vehicle safety system and the warning device, the traders have continuously submitted various related technologies. Among them, for example, Patent Document 1 is typical (as shown in FIG. 1). The portable electronic device 11 of Patent Document 1 includes an imaging lens 12, a speaker 13, an arithmetic unit 14, a display unit 15, and a vibration unit 16. The speaker 13 is provided on the portable electronic device 11. The imaging lens 12 is provided on the portable electronic device 11 and captures a real-time road surface image 121. The display unit 15 is provided on the portable electronic device 11 and is used to display the real-time road surface image 121 described above. The arithmetic unit 14 is provided in the portable electronic device 11 and includes image analysis software 141. The image analysis software 141 indicates whether or not the vehicle is positioned in the roadway by the road surface mark in the real-time road surface image 121. If the vehicle is not located in the roadway, the speaker 13 generates a warning signal 131 to inform the driver that the vehicle has already protruded from the roadway. If the portable electronic device 11 is set to the silent mode, the vibration unit 16 vibrates to inform the driver that the vehicle has already protruded from the roadway. Further, the driver can use the API system to activate the imaging lens 12 to capture real-time road surface information, or directly activate the imaging function originally provided in the portable electronic device 11 to activate the real-time road surface image 121. And the captured image can be sent and displayed on the display unit 15 using real-time transmission technology.

  The steps of the operation method of Patent Document 1 are as shown in FIG. 2, the portable electronic device 11 is activated to enter the driving safety mode, and the real-time road surface image 121 is actually used using the imaging lens 12 in Step 21. To win. Subsequently, in step 22, the real-time road surface image 121 is sent to the arithmetic unit 14 and displayed on the display unit 15. Subsequently, in step 23, the arithmetic unit 14 is used to analyze the real-time road surface image 121 using the image analysis software 141. In step 24, based on the road surface lane line position in the real-time road surface image 121, it is determined whether or not the vehicle protrudes from the roadway. For example, it is determined whether there are only one or two stripes similar to the color of the roadway line in the real-time road surface image 121. If yes, the arithmetic unit 14 at this time It is determined that the vehicle has already protruded from the roadway, and if there are stripes similar to the two roadway colors in the real-time road surface image 121, the arithmetic unit 14 determines that the vehicle is in a safe driving state. If it is outside the roadway, in step 25, the portable electronic device 11 emits a sound to inform the driver that the roadway has already been exceeded. If not, the step 21 is repeated.

  Patent Document 1 solves the drawbacks of a traditional vehicle safety system, but the real-time road surface image 121 photographed by the imaging lens 12 is a kind of real scene image, and is serious with a clear line indication on the viewing angle. It does not give an impression, and it is impossible for the driver to detect the danger of driving from the image before the vibration or voice warning.
