Description

Intelligent anti-collision warning system for people and vehicles going out

Technical Field

The invention relates to a safety warning system, in particular to an intelligent anti-collision warning system for people and vehicles to travel more intelligently by utilizing a mobile communication technology and a network P2P technology.

Background

With the development of automotive technology, according to standards established by the Society of Automotive Engineers (SAE), the automatic driving level of automobiles is currently going to be developed from the second level (L evel 2) to the third level (L3) and the fourth level (L4), but it is known that the self-driving vehicles identify the surrounding environment through sensors, and the solutions are not limited to using light (L irda), video camera, millimeter wave Radar (MMW Radar), and Ultrasonic wave (ultrastronic), but the development has not reached a very mature level so far.

For example, if a front engineering vehicle carrying waste soil flies and causes dust in a full day, the front part of the self-driving vehicle is easy to judge that the front part is an obstacle due to the dust.

In addition, even in severe weather such as rainstorm or snowstorm, it is difficult for the self-driving to detect accurate information such as lane lines and obstacles. At this time, people, Vehicles, roads, and cloud platforms can be effectively connected in series only by the Internet of Vehicles (IoV) technology, so as to "communicate" Vehicles with each other.

Besides the internet of vehicles, the application of High-precision maps (High-precision maps) of 10 mm grade is an important ring in automatic driving. The development of the three technologies enables the automobiles running on the road in the future to have intelligence from inside to outside, and can achieve effective traffic accident prevention and safety warning, so that the automobiles can safely or automatically arrive at the destination. It is known that there are approximately 13 million vehicles worldwide, with passenger vehicles accounting for perhaps about 10 million, none of these vehicles having the aforementioned capabilities of self-driving, sensing, and networking.

Therefore, in view of the above drawbacks, the present inventors propose an intelligent anti-collision warning system for people and vehicles traveling, aiming to provide that the existing vehicles can have partial car networking capability without adding new equipment, so as to make the traveling more intelligent and safer, and the specific architecture and implementation thereof will be described in detail below.

Disclosure of Invention

To solve the problems of the prior art, a primary objective of the present invention is to utilize a global positioning system in combination with a geographic data system to receive the geographic coordinate position of a mobile device after receiving satellite broadcast signals.

Another objective of the present invention is to utilize the architecture technology of the internet system and apply it to the mobile devices or the mobile terminals, so that a peer-to-peer (peer) private P2P network can be directly established between the mobile devices or the mobile terminals, which is a convergence of the mobile communication technology and the network P2P technology.

In view of the above, the present invention provides an intelligent anti-collision warning system for people and vehicles traveling, which includes a plurality of mobile devices, each of which is configured with an application downloaded by a corresponding user; and a positioning device which is linked with the application program and stores the position information of the plurality of mobile devices. Each mobile device at least comprises a processing unit and a prompting unit, wherein the processing unit is used for a user to set the detection range of the respective mobile device, the processing unit is connected with the positioning device to calculate whether the mobile device meets other mobile devices within a set time according to the plurality of pieces of position information, the detection range and the traveling speed of the mobile device, and if the other mobile devices enter a warning range within the set time, the prompting unit is triggered to send a warning signal.

According to an embodiment of the present invention, the warning signal may be an audio signal or a video signal. The system can be provided with a loudspeaker for outputting the sound signal to remind the user. Alternatively, the system may be configured with a display unit for outputting the image signal to remind the user. Or, when the warning signal is a composite signal of sound and image, the loudspeaker and the display unit can be provided at the same time.

In addition, the user can register a personal account and input personal data, share scene streets, or select other mobile device categories to receive through the application. In one embodiment, the category of mobile device may include, but is not limited to, for example, an electronic device carried by a user, an automobile, a locomotive, a bicycle, or other vehicle, etc.

In order to achieve the effect of real-time communication between vehicles, the system provided by the present invention can further utilize a Private communication network (P2P) to link each mobile device within the same detection range, so that authenticated users can continuously share the location information of each mobile device with each other by using the internet P2P technology, thereby achieving the purpose of real-time communication (IM) between groups.

Moreover, when the system disclosed by the invention is applied to a vehicle, so that the vehicle has the functions of internet of vehicles or self-driving, the warning signal can also be selectively accessed to a local driving computer for interpretation, thereby expanding the dynamic conditions of the vehicles, pedestrians and the like in the surrounding environment interpreted by the local driving computer.

In this regard, the present invention provides a safety assistance system for preventing collision during traveling by displaying a map of the area and information of all other mobile devices (including vehicles and pedestrians) within a specific range on a display unit Based on spatial coordinates shared by mobile devices within the specific range, corresponding to the geographic location of the GIS thereof, and calculated by a mobile positioning Service (L position Based Service, L BS), so as to generate an estimated warning that collision with other mobile devices may occur during local traveling.

Detailed Description

In the prior art, most vehicles do not have the capabilities of self-driving, sensing and vehicle networking so far, and thus effective traffic accident prevention and safety warning cannot be achieved. In view of the above disadvantages, the present invention provides an improved intelligent collision avoidance system for people and vehicles. In order to better understand the technical content of the present invention, please refer to fig. 1 of the present invention, which is a schematic diagram of an architecture according to a preferred embodiment of the present invention, as shown in fig. 1, the intelligent human-vehicle travel collision avoidance system disclosed in the present invention includes a plurality of mobile devices 100,100a,100b,100c,100d and a positioning device 200, wherein each of the mobile devices 100,100a,100b,100c,100d is configured with an application downloaded by a corresponding user.

According to the embodiment of the invention, the application program can be, for example, an APP written by using the architecture technology of the Internet system (Internet), and can be downloaded by the user and used by the user. For example, the application program can be installed in each downloaded electronic device of the user, such as: a user's cell phone, tablet computer, personal digital assistant, smart watch, and the like. Alternatively, the application program may be downloaded by the user and installed directly into the electronic chip, such as a GPS chip, of each mobile device 100,100a,100b,100c,100d to form part of the in-vehicle mobile device, or the wearable mobile device. Of course, the type of the application program downloaded and installed in the electronic chip of the mobile device is not limited to the GPS chip. In other embodiments of the present invention, the application program can also be downloaded and integrated into a System On Chip (SOC) of the mobile device, which can also be used to implement the object of the present invention. In this case, each of the mobile devices 100,100a,100b,100c,100d disclosed in the present invention may be classified into: the type of vehicle such as an automobile, a motorcycle, or a bicycle, etc., which is carried by a user. If the mobile device is a vehicle (vehicle), the application program can be downloaded and installed in the electronic equipment of the vehicle (vehicle); alternatively, the application program can be downloaded and installed in other electronic chips such as a GPS chip or a collision avoidance prompt provided in the vehicle (vehicle), and the application program can be used to implement the object of the present invention.

The pointing device 200 is linked to the application program to store the location information of each mobile device 100,100a,100b,100c,100 d. According to the embodiment of the present invention, the position Information of the mobile devices 100,100a,100b,100c,100d is presented by a Global Positioning System (GPS) and a Geographic Information System (GIS), i.e. a composite System using the GPS and the GIS is disclosed, wherein the Geographic Information System can flexibly select different levels of maps according to different users.

For example, the system disclosed herein can distinguish between general users and high-level users, and when the user belongs to a general user, the system can configure a general Google map or choose to use the original configuration map of the vehicle itself. For example, when the user belongs to a high-level user, the system may configure a high-precision map and display the location information of the corresponding mobile device on a level of, for example, 10 mm.

Referring to fig. 2, which is a schematic structural diagram of a mobile device according to an embodiment of the present invention, as shown in the figure, taking the mobile device 100 as an example, the mobile device 100 at least includes a processing unit 102 and a prompting unit 104, and the processing unit 102 may be, for example, a Microprocessor (MCU) for a user to set a detection range of the mobile device 100.

In detail, according to the embodiment of the present invention, when the user downloads the application program, the user may first register a personal account and input personal data, share a scene street, or select a category of another mobile device that the user wants to receive through the application program, and then start using the mobile device after the user passes through the authentication procedure. Wherein, the personal data can include the brand, model and color of the vehicle; other mobile device categories that are intended to be received may include, for example, but not limited to, automobiles, trucks, fire trucks, locomotives, or pedestrians, among others. The types of the shared scene may include, but are not limited to, a roadway, a general road, an expressway, and the like.

Then, when the user uses the processing unit 102 to set the detection range of the mobile device 100, the system will use the geographical location where the user is located as a central point, thereby setting a longer detection range in the vertical direction and a shorter detection range in the horizontal direction, and presenting all the other users and dynamic alerts within the geographical location range of the mobile device that are verified within the detection range. According to the embodiment of the invention, the detection range can be used for knowing the position of the mobile device through map positioning. The detection range is defined as a longitudinal distance and a transverse distance, wherein the longitudinal distance can be defined by a user, and the transverse distance is related to the width of the road range.

In consideration of the setting of the longitudinal distance, the user must first select the traveling speed and the number of traveling seconds of the corresponding mobile device, and if the mobile device is a vehicle, the traveling speed and the number of traveling seconds of the vehicle. Taking the vehicle as a central point, setting the forward distance M meters and the backward distance 0.5M meters according to the set speed, and then setting the total longitudinal distance to be 1.5M meters.

In the case of an expressway or an expressway, when the vehicle has a speed of 100 km/h and a travel time of 15 seconds, a longitudinal distance of 625 meters is defined by taking the vehicle as a center, 417 meters ahead and 208 meters behind. In the case of a general road, when the speed per hour of the vehicle is 60 km/h and the number of traveling seconds is 15 seconds, the longitudinal distance is 375 m, which is defined by taking the vehicle as the center, moving forward 250 m and backward 125 m.

Regarding the setting of the transverse distance, regarding the expressway and the expressway, the width of the expressway or the expressway marked by the map is taken as the standard; if a general road is considered to be the vehicle coming from the left and right lateral roads, the vehicle is taken as the center point, and the left and right directions are not less than 40 meters, i.e. the total lateral distance width is at least 80 meters. This data comes from the minimum safe distance data provided by the high-rise public.

Thus, in one embodiment, if the location information to which the mobile device belongs to an expressway, the detection range may be set to a range of 625 meters in the longitudinal direction and 30 meters in the transverse direction, for example. In another embodiment, if the location information to which the mobile device belongs to a general road, the detection range can be set to a range of 375 meters in the vertical direction and 80 meters in the horizontal direction.

Accordingly, the processing unit 102 is linked to the positioning device 200 to calculate whether the other

mobile device

100a,100b,100c or 100d is encountered within a set time according to the position information of the mobile device 100, the detection range and the traveling speed of the mobile device 100, wherein the set time can be set to 10 seconds, 20 seconds or 1 minute, for example, according to an embodiment of the present invention. Then, the processing unit 102 calculates that if there are other

mobile devices

100a,100b,100c, or 100d entering the local warning range in the setting time while maintaining other conditions and without decelerating, the driving prompting unit 104 sends a warning signal.

Please refer to fig. 3, which is a diagram illustrating an alert range 300 when a mobile device 100d enters the mobile device 100 according to an embodiment of the present invention. As shown in the figure, the prompt unit 104 is triggered to send an alarm signal to remind the user. According to an embodiment of the present invention, when the distance between the mobile device 100 and the mobile device 100d divided by the speed of the mobile device 100 is less than 3 seconds, the system drives the prompting unit 104 to send the warning signal to remind the user.

The warning signal may be an audio signal (audio), a video signal (video), or a composite signal of both.

In one embodiment, when the warning signal includes an audio signal, a speaker 108 may be configured to output the audio signal to alert the user. In this embodiment, the speaker 108 may be, for example, a horn, a car audio, or a buzzer.

In another embodiment, when the warning signal includes an image signal, the system may be configured with a display unit 106 for outputting the image signal to remind the user. According to an embodiment of the present invention, the display unit 106 may be, for example, a device screen in a vehicle or a head-up display (HUD) of a vehicle, but the present invention is not limited thereto, and those skilled in the art can modify and change the design thereof according to the actual implementation thereof without departing from the scope of the present invention.

Furthermore, when the display unit 106 is disposed in the mobile device 100, the images of all the other

mobile devices

100a,100b,100c,100d can also be displayed on the display unit 106 for the user to view. When the vehicle has the function of internet of vehicles or self-driving, the warning signal can also be selected to be accessed to the local running computer for interpretation, thereby enlarging the dynamic condition of the local running computer for interpreting the surrounding vehicles or pedestrians.

Furthermore, in consideration of safety driving, as shown in fig. 2, if the mobile device 100 is further provided with a deceleration unit 110, if necessary, when the processing unit 102 calculates that other

mobile devices

100a,100b,100c,100d will be encountered within a predetermined time, and the distance between the mobile device 100 and the other encountered mobile devices divided by the speed of the mobile device 100 is less than 2 seconds, the deceleration unit 110 on the mobile device 100 may be triggered to achieve the effect of automatic deceleration, thereby avoiding collision.

In an embodiment of the present invention, when the plurality of mobile devices are vehicles, a Vehicle manufacturing company may provide an official account Number, and use a Vehicle Identification Number (VIN) of each mobile device as a sub-account Number, so as to use the sub-account numbers as a key for sharing information among the mobile devices. Please refer to fig. 4, which is a diagram illustrating a plurality of mobile devices connected by a private communication network according to an embodiment of the present invention. In this case, each of the mobile devices 100,100a,100b,100c,100d in the same detection range 400 may be connected to each other by a Private communication network (Private Peer to Peer, P2P), so that the authenticated participants can continuously share the location information of each of the mobile devices 100,100a,100b,100c,100d with each other through the internet P2P technology. Moreover, by means of the important technical features, the intelligent anti-collision warning system for people and vehicles traveling disclosed by the invention can further provide the purpose of Instant Messaging (IM) of specific groups within the same detection range 400, such as locomotive fleets, bicycle fleets, or even automobile fleets, and the like, so as to achieve the effect of real-time mutual connection and communication among vehicles, and further expand the application scope of the invention.

The intelligent anti-collision warning system for people and vehicles traveling provided by the invention is Based on the space coordinates shared by the mobile devices in a specific range, corresponds to the geographic position of the GIS of the mobile devices, and displays the area map and the information of all other mobile devices (including vehicles and pedestrians) in the specific range by utilizing a head-up display of the device screen or the vehicle after calculation Based on a mobile positioning Service (L position Based Service, L BS), so as to generate an estimation warning which is possible to collide with other mobile devices in local traveling, thereby providing a safety auxiliary system for preventing collision in the traveling process.

The invention can be applied to pedestrians, especially blind persons or children, and because the visually impaired people are actually more difficult to move than ordinary people, various obstacles which are large and small on roads and in the environment are quite dangerous for the visually impaired people who have not been trained to move directionally; similarly, children walk on roads and in the environment, and because the reaction is not as quick as adults, it is not easy to judge whether dangers exist in the surrounding road environment, so when the invention is applied to blind persons or children, the practicability is higher, vehicles around can accurately identify the positions of the blind persons or children, the collision with the blind persons or children is avoided, and the purpose of protecting the road safety of the blind persons and children is achieved. The blind and children can also receive the position information of other vehicles by wearing the intelligent watch (or mobile phone) provided with the system, and can remind the blind and children by vibration or warning sound when the other vehicles enter a set range. Although a winding road may be used at night or between suburban mountains, it may also have a considerable accuracy. In addition, especially when the system is applied to bad weather or the existing sensing signal is blocked by the front vehicle or the side vehicle to cause judgment errors, the warning signal sent by the system becomes one of the most important judgment sources.

In addition, when the intelligent anti-collision warning system for the people and the vehicle to go out disclosed by the invention always hears the whistle of an ambulance or a fire engine and the like during the automobile traveling but does not know the exact direction and position of the whistle, the intelligent anti-collision warning system for the people and the vehicle to go out still can preferentially broadcast the geographical positions of the vehicles which have the priority to pass so as to achieve the effect of warning users whether the traveling speed of the intelligent anti-collision warning system meets local people and vehicles within a set time.

Furthermore, the intelligent anti-collision warning system for people and vehicles going out provided by the invention can also be designed to provide a preliminary warning signal for vehicles gathering into the trunk road on the lateral transverse road. To sum up, based on the long-standing problems of the prior art, the present invention is directed to solving these shortcomings, and thus providing an innovative auxiliary safety warning system, which effectively reduces the occurrence of traffic accidents and improves the road safety of users by integrating the system.

Furthermore, in the embodiment shown in fig. 4, if the mobile devices are electronic devices carried by a group of users, in other words, when a group of users make a trip together, the users can respectively use the application disclosed by the present invention to set up a temporary trip group, in the temporary trip group, the usage scenario of the road or application range is not limited to general roads, roadways, or mountain roads, footpaths, etc., and the users downloading the same application can expand the communication range to infinity by the communication function of the group. Moreover, the display device can be used with the original display function in a laminated mode. For example, referring to fig. 5, the position image signals of the co-travelers (corresponding to the mobile devices 100e and 100f) outside the predetermined detection range 400 can be independently displayed on the display unit in a reduced window or other manner, so that the P2P technology can be used among the users of the co-traveling group to achieve the purpose of individual communication or group communication.

In addition, according to other embodiments of the present invention, the aforementioned applications can also be extended to navigation applications, especially in sightseeing and touring group scenes, but the present invention is not limited thereto, and in this way, the leader can utilize the communication function to perform applications such as scenic spot explanation and personnel position control.

Therefore, in view of the above, compared with the prior art, it is obvious that the intelligent anti-collision warning system for people and vehicles traveling disclosed by the invention has excellent industrial utilization and competitiveness, and overcomes the defects of the sensing system used by the traditional vehicle or the vehicle with the self-driving sensing equipment, and more than 10 hundred million passenger vehicles are suitable for installation and application at present. It is thus evident that the technical features, methodological acts, and effects disclosed in the present application are significantly different from those of the prior art.
