Please refer to fig. 1, which is a flowchart illustrating a method for collision avoidance according to a first embodiment of the present invention. The method for preventing collision of the vehicle provided by the first embodiment specifically comprises the following steps.
Step S101, obtaining the automobile running information of the current automobile and the bicycle running information of the current bicycle. The vehicle travel information includes a vehicle position, a vehicle speed, and a vehicle travel path, and the bicycle travel information includes a bicycle position, a bicycle speed, and a bicycle travel path.
Specifically, please refer to fig. 7 in combination, the first electronic device 100 and the second electronic device 200 are utilized to obtain a vehicle position, a vehicle speed, a vehicle traveling path, a bicycle position, a bicycle speed, and a bicycle traveling path. The first electronic device 100 includes a first memory 101, a first processor 102, a first speed sensor 103, a first communication component 104, a first display component 105, an angle measurement component 106, and an automatic door locking component 107. The second electronic device 200 includes a second memory 201, a second processor 202, a second speed sensor 203, a second communication component 204, a second display component 205, and an automatic braking component 206.
For example, the first memory 101 and the second memory 201 store software such as a GPS system and a height map, the first processor 102 and the second processor 202 use the GPS system to locate the current position of the car or the bicycle, and use navigation software such as a height map to obtain the driving route of the car or the bicycle. And control other components to perform various tasks. The first speed sensor 103 and the second speed sensor 203 are used to obtain the vehicle speed and the bicycle speed. The angle measurement assembly 106 is used to measure the angle of the vehicle when it is driven. The first communication component 104 and the second communication component 204 are used for sending the information related to the automobile and the bicycle to the server 900, and receiving the locking signal, the braking signal and the deceleration signal from the server 900. The deadlock signal is used for automatically locking the door assembly 107, and when a dangerous condition is met, the automatically locking door assembly 107 cannot open the vehicle door within a certain time after receiving the deadlock signal. The braking signal and the deceleration signal are applied to the brake actuating assembly 206, and when a dangerous situation is encountered, the braking signal and the deceleration signal control the automatic brake assembly 206 to brake or decelerate. The first display assembly 105 and the second display assembly 205 convert the received warning signal into a sound or display signal that can attract the attention of the passengers and the riding personnel.

Specifically, in this embodiment, the time standard is set to 3 seconds, 10 seconds are longer than 3 seconds, and the bicycle riding personnel have enough time to avoid the automobile, so send the early warning signal to the bicycle.
In some other possible embodiments, after the bicycle receives the prompting signal, the information in the prompting signal is output through a vehicle-mounted output device such as a display device or a voice device so as to achieve the effect of reminding the riding personnel of paying attention to the surrounding automobiles.
And step S108, when the reaction time is less than or equal to the time standard, sending a preset emergency processing signal to the automobile and the bicycle. Specifically, when the reaction time is less than 3 seconds, a locking signal is sent to the automobile and/or a braking signal or a deceleration signal is sent to the bicycle according to actual conditions.

8. A method for vehicle collision avoidance according to claim 5, wherein the emergency processing signals include a lock-up signal, a brake signal and a deceleration signal, and when the reaction time is less than or equal to the time criterion, an early warning signal is sent to the bicycle, specifically comprising:
when the travel distance is less than the preset second criterion and the reaction time is less than or equal to the time criterion, sending the lock-up signal to the automobile and/or sending the brake signal or the deceleration signal to the bicycle.
9. A method for vehicle collision avoidance according to claim 5, wherein the emergency processing signals include a lock-up signal, a brake signal and a deceleration signal, and when the reaction time is less than or equal to the time criterion, an early warning signal is sent to the bicycle, specifically comprising:
sending the brake signal or the deceleration signal to the bicycle when the travel distance is less than the second criterion for opening the door and the reaction time is less than or equal to the time criterion.
10. A server, characterized in that the server comprises:
a memory for storing program instructions for a method of vehicle collision avoidance; and
a processor for executing the program instructions to cause the server to implement a method of vehicle collision avoidance as claimed in any one of claims 1 to 9.
11. A vehicle collision avoidance system, characterized in that the vehicle collision avoidance system comprises:
a server according to claim 10;
the first electronic device comprises a first memory and a first processor, the first electronic device is installed on an automobile, the first memory is used for storing program instructions, and the first processor is used for executing the program instructions to acquire and send the automobile position, the automobile speed and the automobile driving path of the automobile to the server; and
a second electronic device including a second memory and a second processor, the second electronic device being mounted to a bicycle, the second memory being for storing program instructions, the second processor being for executing the program instructions to obtain and send to the server a bicycle position, a bicycle speed, and a bicycle travel path of the bicycle.
