Problems solved by technology

However, wireless communication lacks timeliness and cannot play a role when a collision is about to occur. It can only serve as a warning and cannot brake the vehicle; moreover, the system cannot obtain pedestrian information in the blind area of ​​the intersection, and lacks protection for pedestrians at the intersection. measure
[0006] The patents with the application numbers "201420845772.0" and "201210214879.0" only assist the driver in avoiding collisions in one way, the fault tolerance rate is relatively low, and there are certain limitations for the driver's assistance, and the pedestrian information in the blind area of ​​the intersection cannot be collected. For pedestrians who are about to pass through the intersection, it cannot play the role of collision avoidance, so it is necessary to propose a vehicle avoidance and collision avoidance system at intersections without signal lights

Embodiment 1

[0082] refer to figure 1 , the host car 2 communicates with the target car 3 through the wireless communication module 10, obtains relevant driving information of the target car 3, judges the driving intention of the driver of the target car 3 through the central processing module 12, and judges whether there is a potential collision risk, and sends the intersection The situation is communicated to the driver through the HIM interface of the collision warning module 13 . The main vehicle 2 obtains the driving information of the short-distance target vehicle 1 through the millimeter-wave radar, and judges the driving intention of the driver of the target vehicle 1 through the central processing module 12. If there is a collision risk, the collision warning module 13 is triggered to remind the driver. Control the braking control module 14 to perform vehicle braking.

Embodiment 2

[0084] refer to figure 2 , the host vehicle 5 communicates with the target vehicle 4 and the target vehicle 6 through the wireless communication module 10, and the target vehicle 4 and the target vehicle 6 communicate. The host car 5 obtains the relevant driving information of the target car 4 and the target car 6, judges the driving intention of the driver of the target car 3 through the central processing module 12, judges whether there is a potential collision risk, and passes the intersection status through the HIM interface of the collision warning module 13 passed on to the driver.

Embodiment 3

[0086] refer to image 3 , the intersection terminal 8 detects the walking speed and the distance from the intersection of the pedestrian 9 in the blind spot through the intersection situation perception module 16 . The main vehicle 7 obtains pedestrian related information through the communication between the wireless communication module 10 and the intersection communication module 15 and transmits it to the central processing module 12. The central processing module 12 judges whether there is a collision risk by comparing its own information with the pedestrian information. If there is a risk of collision, the central processing module 12 transmits danger information to the intersection communication module 15 through the wireless communication module 10, and the intersection information processing module 17 receives the information and controls the intersection warning module 18 to give an alarm to remind passers-by. 12 information to remind the driver to do evasive action...

Abstract

The invention belongs to the field of intelligent safe driving, and particularly discloses a people-avoidance and collision-avoidance system and method for vehicles at a crossroad without signal lights. The system includes a crossroad terminal, a wireless communication module, a vehicle information acquisition module, a central processing module, a collision pre-warning module and a brake controlmodule; the crossroad terminal, the wireless communication module, the vehicle information acquisition module, and the collision pre-warning module are connected with the central processing module. The system is a system based on an LTE-V communication mode, a millimeter-wave radar and GPS positioning, through a vehicle-vehicle communication mode and a vehicle-road communication mode, the states of pedestrians at the dead zone of the crossroad and the motion states of surrounding vehicles are obtained, whether risks of collision exist or not is judged, alarming is conducted through a HIM interface so as to remind a driver of reducing the speed or changing lanes, and when necessary, the speed of a vehicle is controlled to be reduced so as to avoid collision.

Description

technical field [0001] The invention belongs to the field of intelligent safe driving, and specifically shows a system and method suitable for avoiding people and collisions of vehicles at intersections without signal lights. Background technique [0002] According to incomplete statistics from the National Bureau of Statistics of the People's Republic of China, a total of 187,781 traffic accidents occurred nationwide in 2015, among which the incidence of traffic accidents at intersections without signal lights is relatively high. When the vehicle passes through the intersection without signal lights, the driver's attention is more concentrated on the front, and the situation on both sides of the intersection is not observed enough, which may easily lead to a collision with pedestrians who are about to pass through the intersection, and the vehicle speed at the intersection without signal lights is relatively fast. High, the damage caused by collision with pedestrians or oth...
