The present invention relates to a safety warning system, in particular to a smart collision avoidance warning system that uses mobile communication technology to integrate network P2P technology to make travel more intelligent.

According to the progress of automobile technology, according to the standards set by the Society of Automotive Engineers (SAE), the current level of auto driving is continuing from the second level (Level 2) to the third level (L3), The fourth level (L4) development. However, it is currently known that self-driving cars use sensors to recognize the surrounding environment. Its solutions are nothing more than the use of LiDAR, cameras, MMW Radar, and Ultrasonic, etc., but development So far, these solutions have not yet reached a very mature level. For example, the information collected by a self-driving car is still limited to a single vehicle level. If it is a blind spot that cannot be detected by the vehicle, or if an emergency occurs in an invisible distant place, the Internet of Vehicles must be used to obtain further information. Supplementary information.

Another example is the radar with the most stable detection effect. In addition to being expensive and unable to be widely used, its judgment accuracy is not accurate enough. For example, if an engineering vehicle carrying spoiled soil is flying away in front, causing the sky to be covered with dust, The self-driving car is likely to judge that there are obstacles ahead due to the dust.

In addition, when encountering severe weather such as storms or snowstorms, it is also difficult for self-driving cars to detect the correct lane line and obstacles. At this time, only through the Internet of Vehicles (IoV) technology can people, vehicles, roads, and cloud platforms be effectively connected together so that vehicles can "communicate" with each other.

In addition to the Internet of Vehicles, the application of 10mm high-precision map (High-precision map) is a very important part of autonomous driving. The development of these three technologies will make future cars running on the road smart from inside to outside, and can achieve effective traffic accident prevention and safety warnings, so that they can reach their destinations safely or autonomously.

As shown in the figure, taking the mobile device 100 as an example, the mobile device 100 includes at least a processing unit 102 and A prompt unit 104 and the processing unit 102 can be, for example, a microprocessor (MCU) for the user to set the detection range of the mobile device 100.

In detail, according to an embodiment of the present invention, when a user downloads an application, the user can first register a personal account through the application and enter personal information, share the scene street, or select the category of other mobile devices that they want to receive , And can be used after verification procedures. Among them, the personal data may include the make, model, and color of the vehicle; other types of mobile devices that you want to receive may include, but are not limited to, cars, trucks, fire trucks, locomotives, or pedestrians. The categories of participating sharing scenes may also include, but are not limited to, roadways, general roads, express roads, or highways, etc.

Subsequently, when the user uses the processing unit 102 to set the detection range of the mobile device 100, the system will use the geographic location where the user is located as a center point, thereby setting a detection range that is longer in the vertical direction and shorter in the horizontal direction. Within this detection range, dynamic alerts of all other verified users and their mobile devices within the geographic location range are presented. According to an embodiment of the present invention, the detection range can be used to know the location of the mobile device through map positioning. Among them, the detection range needs to define a longitudinal distance and a lateral distance. Generally speaking, the longitudinal distance can be defined by the user, and the lateral distance is related to the width of the road range being driven.

When considering the setting of the longitudinal distance, the user must first select the corresponding traveling speed and traveling seconds of the corresponding mobile device. If the mobile device is a vehicle, it will be the traveling speed and traveling seconds of the vehicle. With the vehicle as the center point, the forward distance is M meters based on the set speed, plus the backward distance of 0.5M meters, the total longitudinal distance between front and rear is 1.5M meters.

In terms of expressways and expressways, when a vehicle travels at a speed of 100 km/h and the travel time is 15 seconds, the vehicle will be centered at 417 meters forward and 208 meters backward, which defines the longitudinal direction The distance is 625 meters. In terms of a general road, when the vehicle speed is 60 km/h and the travel seconds is 15 seconds, the vehicle will be the center, 250 meters forward and 125 meters backward, to define the longitudinal distance It is 375 meters.

As for the setting of the horizontal distance, for expressways and expressways, it is based on the width of the expressways or expressways marked on the map; if it is a general road, considering the traffic on the left and right lateral roads, it is The vehicle is the center point, and the left and right directions must not be less than 40 meters, that is, the total width of the horizontal distance must be at least 80 meters. This information comes from the minimum safety distance data provided by the High Commission.

Therefore, in one embodiment, if the location information to which the mobile device belongs belongs to an expressway, the detection range can be set to, for example, a range of 625 meters in the vertical direction and 30 meters in the horizontal direction. In another embodiment, if the location information to which the mobile device belongs 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.

For this reason, the processing unit 102 is connected to the positioning device 200 to calculate whether it will encounter other mobile devices 100a, 100b, 100c or other mobile devices 100a, 100b, 100c or other mobile devices within a set period of time based on the location information of the mobile device 100, the detection range and the traveling speed of the mobile device 100 100d. According to an embodiment of the present invention, the set time can be set to, for example, 10 seconds, 20 seconds, or 1 minute. After that, the processing unit 102 calculates that if other mobile devices 100a, 100b, 100c, or 100d enter the local warning range when other conditions remain unchanged and do not decelerate within this set time, the driving reminding unit 104 will issue A warning signal.

Please refer to FIG. 3, which is a schematic diagram of a warning area 300 of the mobile device 100 when a mobile device 100d enters according to an embodiment of the present invention. As shown in the figure, the prompt unit 104 will be triggered at this time, and a warning signal will be issued 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 issue the warning signal to remind the user.

Wherein, the warning signal can 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 in the system to output the audio signal to remind the user. In this embodiment, the speaker 108 can be, for example, a horn, an in-car audio, or a buzzer.

As for, in another embodiment, when the warning signal includes an image signal, a display unit 106 may be configured in the system to output 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 car or a vehicle head-up display (HUD). However, the present invention is not limited to this. Those with ordinary knowledge in the field should be able to According to the technical enlightenment of the invention, the design is modified and changed according to its actual implementation level, which all belong to the scope of the invention.

Furthermore, when the display unit 106 is provided in the mobile device 100, the images of all other mobile devices 100a, 100b, 100c, and 100d can also be displayed on the display unit 106 for viewing by the user. When the vehicle has the function of car networking or self-driving, the warning signal can also be connected to the local driving computer for interpretation, which can expand the local driving computer to interpret the dynamic conditions of surrounding vehicles or pedestrians.

Moreover, based on the consideration of safe self-driving, as shown in Figure 2, if necessary, the mobile device 100 can be provided with a deceleration unit 110. When the processing unit 102 calculates that it will encounter other mobile devices 100a, 100b, 100c within the set time , At 100d, and the distance between the mobile device 100 and other encountering 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 can be triggered to achieve the effect of automatic deceleration and avoid The collision occurred.

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 the vehicle identification number (VIN) of each mobile device as a sub-account. Use these sub-accounts as the key for sharing messages between the mobile devices. Please refer to FIG. 4, which is a schematic diagram showing that a plurality of mobile devices can be connected by a private communication network according to an embodiment of the present invention. In this case, each mobile device 100, 100a, 100b, 100c, 100d within the same detection range 400 can be connected to each other by a private communication network (Private Peer to Peer, P2P), so that Participants of the authentication can continuously share the location information of each mobile device 100, 100a, 100b, 100c, 100d by using Internet P2P technology. Moreover, with this important technical feature, the intelligent collision avoidance warning system for pedestrians and vehicles disclosed in the present invention can further provide instant messaging (IM) for specific groups within the same detection range 400, such as locomotives Fleet, bicycle team, or even car fleet, etc., achieve the effect of real-time connection and communication between vehicles, thereby expanding the scope of application of the present invention.

The reason is that the intelligent collision avoidance warning system for pedestrian and vehicle travel disclosed in the present invention is based on the spatial coordinates shared by mobile devices within a specific range, corresponding to its GIS geographic location, and calculated based on the Location Based Service (LBS). Use the device screen or the head-up display of the vehicle to display the area map and the information of all other mobile devices (including vehicles and pedestrians) within a specific range to generate an estimated warning that may collide with other mobile devices during local travel, thereby providing A safety assist system to prevent collisions during travel.

The present invention is more applicable to pedestrians, especially blind people or children. Because visually impaired people are indeed more difficult to move than ordinary people, various obstacles on the road and in the environment are very important for visually impaired people who have not been trained in directional movement. In other words, it is quite dangerous; similarly, children walking on roads and the environment, because they are not as quick as adults, and it is not easy to judge whether there is danger in the surrounding road environment. Therefore, when applying the present invention to blind people Or children, it is more practical, so that the surrounding vehicles can accurately identify their location, avoid collisions with them, and achieve the purpose of protecting the blind and children's road safety. Blind people and children can also receive other vehicle location information by wearing smart watches (or mobile phones) equipped with this system, and alert them with vibrations or warning sounds when other vehicles enter the set range. Although it is a winding road at night or in the suburban mountains, it can be quite accurate. In addition, especially when used in bad weather, or when the conventional sensing signal is blocked by the preceding vehicle or the next vehicle, causing a judgment error, the warning signal issued by the system will become one of the most important judgment sources.

In addition, when a car often hears the horn of an ambulance or fire truck while traveling, but does not know its exact direction and location, regardless of whether its traveling speed will meet the local people and vehicles within a set time, the present invention The disclosed intelligent collision avoidance warning system for human and vehicle travel will still give priority to these geographical locations with priority vehicles to achieve the effect of warning users.

Furthermore, the intelligent anti-collision warning system for pedestrian and vehicle travel disclosed in the present invention can also be designed to provide preliminary warning signals for vehicles that merge into the main road from the lateral road. Therefore, to sum up, based on the long-standing problems of the prior art, the present invention aims to solve these shortcomings and proposes an innovative safety warning auxiliary system. The integration of this system can effectively reduce traffic accidents. Occurs, and at the same time enhance the safety of the user’s road.

Furthermore, in the embodiment shown in Figure 4 above, if the mobile devices are electronic devices carried by a group of users, in other words, when a group of users agree to travel together, the users can Each uses the application disclosed in the present invention to set up a temporary travel group. In this temporary travel group, the usage scenarios of its roads or application areas are not limited to general roads, lanes, or mountain roads, trails, etc. These users who have downloaded the same application can use the communication function of the group to extend their communication range to infinite. In addition, it can be stacked with the original display function. For example, please refer to Figure 5, the location image signal of the common travelers outside the original detection range 400 (corresponding to the mobile devices 100e, 100f) can be displayed on the display unit in an independent zoom window or in other ways , So that users of this common travel group can use P2P technology to achieve the purpose of individual communication or group communication.

In addition, according to other embodiments of the present invention, the aforementioned application can also be extended to guide use, especially in the scene of tourist groups, but the present invention is not limited to this. According to this application method, the team leader can use This communication function is used for applications such as scenic spot explanation and personnel location control.

Therefore, in view of the above, compared with the conventional technology, it can be clearly seen that the intelligent collision avoidance warning system for pedestrian and vehicle travel disclosed in the present invention does have excellent industrial applicability and competitiveness. At the same time, it also solves the problem of There are many shortcomings of traditional vehicles or the sensing systems used in vehicles with self-driving sensing equipment. Currently, more than 1 billion passenger cars worldwide are suitable for installation. This shows that the technical features, methods and effects achieved by the present invention are significantly different from the current solutions. They are not something that can be easily completed by those who are familiar with the technology. Therefore, they should have the patent requirements. Jian Zhi.
