Description

Driving recorder and distance warning method with vehicle distance warning and map display function

This creation department is about a driving recorder, especially for driving recorders and distance warning methods with vehicle distance warning and map display functions.

The industrial and commercial development, heavy traffic, and the intersection of traffic and water are the portrayal of modern society, and this has greatly increased the probability of accidents in various vehicles. Although the vehicle is fast and convenient, the weight of the vehicle is huge and the moving speed is fast. Therefore, the object with large inertia and impulse can not switch its path immediately when driving. Generally speaking, the average human reaction force is 0.75 seconds. The standard, the reaction distance at various speeds is estimated, the reaction distance of about 13 meters is required at a speed of 60 kilometers per hour, and the reaction distance is as high as 21 meters at a speed of 100 kilometers per hour, so that it is easy to contact him with a slight accident when driving. Cars collide, and modern people are busy, often multi-tasking, or more prone to accidents when they are mentally exhausted. In the event of an accident, they are able to effectively clarify the responsibility and rely on the identification of professional personnel.

The difficulty of anecdotal identification is no more than evidence, limited information, from a variety of fragmentary site conditions, such as vehicle tracks, impact angles, collision levels and other information, it is difficult to restore the scene of the accident, in addition to the need for high standards of light and judgment In addition to force, it still takes a lot of time, so if it can be completely retained Information such as driving behavior, especially information for a period of time before the accident time, can effectively speed up the identification of accidents and improve accuracy.

The invention provides a driving recorder with a vehicle distance warning and a map display function, so as to improve the reference of the conventional driving information record, the reference is too single, the accuracy is limited, and the reference value is low.

The invention provides a driving recorder with a vehicle distance warning and a map display function, which is suitable for a vehicle, comprising a display unit, a satellite positioning unit, an image capturing unit, a map database, and a distance sensing unit. And an arithmetic processing unit. The satellite positioning unit obtains one position information of the vehicle, the image capturing unit obtains at least one continuous image when the vehicle travels, the map database stores at least one electronic map, and the arithmetic processing unit determines the vehicle and the other device during the driving of the vehicle. Whether the distance between the vehicles is less than a safe distance to display a reminder message and an electronic map through the display unit, and obtain a continuous image of the vehicle traveling to the destination through the image capturing unit.

The invention provides a vehicle distance warning method, which is applicable to a vehicle, comprising: storing at least one map data in a map database, and obtaining a position information of a vehicle by a satellite positioning unit, and then transmitting an image capturing unit Obtaining at least one continuous image of the carrier as it travels, and sensing the distance between the carrier and the other carrier by a distance sensing unit. Then, an arithmetic processing unit determines whether the distance between the vehicle and the other vehicle is less than a safe distance. If the distance is less than the safety distance, a warning signal is sent through the warning unit, if the distance between the two is Above the safe distance, a reminder message and map data are displayed through a display unit.

In an embodiment of the present invention, the driving recorder having the vehicle distance warning and map display function further includes an alerting unit to provide a warning signal.

In an embodiment of the present invention, the distance sensing unit is configured to calculate at least one continuous image when the carrier is obtained by the image capturing unit to calculate an interaction with another vehicle by using an image recognition algorithm. distance.

FIG. 1B is a flow chart corresponding to the step of the vehicle distance warning method of FIG. 1A. 2 is a schematic view of a display unit of the driving recorder of the present invention. In FIG. 1 , a driving recorder with a vehicle distance warning and a map display function is applicable to a vehicle. The driving navigation recorder includes a display unit 110, a satellite positioning unit 120, an image capturing unit 130, and a map database. 140, a distance sensing unit 150 and an arithmetic processing unit 160. The map database 140 stores at least one electronic map 141, (step S110) satellite positioning The unit 120 obtains the position information 121 of the carrier (step S120), and the image capturing unit 130 obtains at least one continuous image 131 when the carrier travels (step S130), and the distance sensing unit 150 senses the carrier and another carrier. The distance between (step S140).

The arithmetic processing unit 160 determines whether the distance between the vehicle and the other vehicle is less than a safe distance between the vehicles (step S150), and if so, the one set by the driving recorder with the vehicle distance warning and the map display function. The alert unit 170 issues a warning signal 162 (step S160). If not, a reminder message 161 and an electronic map 141 are displayed on the display unit 110, and the continuous image of the vehicle 200 traveling to the destination is obtained by the image capturing unit 130 (step S170). If there is no problem that the distance from the other carrier is too short, the display unit 110 displays the continuous image and the electronic map 141 acquired by the image capturing unit 130 (as shown in FIG. 2).

In this embodiment, the distance sensing unit is configured to calculate a distance from another carrier by using an image recognition algorithm according to at least one continuous image of the vehicle traveled by the image capturing unit.

In this embodiment, the driving recorder further sets a time recorder to record continuous images of the respective position information of the carrier and the time points of the passing.

Please refer to FIG. 3 and FIG. 4 at the same time. FIG. 3 is a schematic diagram of the warning of the distance warning of the line shop recorder in an embodiment of the present invention. 4 is a warning reminder of a vehicle with a temporary insertion distance too short in the front lane of the workshop according to an embodiment of the present invention; intention. In FIG. 3, when the vehicle 200 is traveling on the road, the display unit 110 of the driving navigation recorder of the vehicle distance warning function displays at least one continuous image when the vehicle 200 captured by the image capturing unit 130 travels. 131. The continuous image 131 includes a carrier image 201A of another carrier 200A. If the distance between the vehicle and the other vehicle is temporarily less than a safe distance in the front road, a reminder message 161 is displayed on the display unit 110 to remind the vehicle to display the warning and map display function. The vehicle of the driving recorder is aware of the driving situation of the vehicle ahead and avoids collision.

While the present invention has been described above in the foregoing embodiments, it is not intended to limit the invention, and the equivalents of the modifications and retouchings are still in the present invention without departing from the spirit and scope of the invention.
