Problems solved by technology
After the investigation and analysis of the traffic accident data, it was found that the following traffic accidents have a certain proportion: when there is a zebra crossing in front of the vehicle, the driver is paralyzed and careless due to the stopped interfering car blocking one end of the zebra crossing, passing the zebra crossing at high speed, and colliding with the sudden pedestrians crash, resulting in a tragic traffic accident
The main cause of the accident is that the distance between the vehicles passing the zebra crossing and the sudden pedestrians is too close, the vehicle speed is too high, and the braking distance is too short, so that it is too late for manual braking. Such traffic accidents cannot be avoided within the distance

Embodiment Construction
[0042] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0043] Such as figure 1 As shown, the specific implementation includes vision system 1, which captures the road image in front of the vehicle, and recognizes the zebra crossing on the road ahead and the interfering vehicles on both sides of the road through image analysis, and obtains the position of the zebra crossing (i.e. sidewalk), the position of the interfering vehicle and Vehicle condition information such as the position of the zebra crossing, the position of the interfering vehicle and the relative position of the vehicle track, and the vehicle condition information is sent to the main control system through the CAN network 4; the interfering vehicle is usually a bus or a truck, etc., but not limited thereto.
[0044] It includes the main control system 2, which receives the vehicle condition information of the visual system ...

The invention discloses an anti-collision control system for pedestrian shielding by zebra crossing sight based on a visual system. Comprising a visual system which is used for shooting images of roads in front of a vehicle, identifying vehicle condition information through image analysis and sending the vehicle condition information to a main control system; comprising a master control system for receiving vehicle condition information of a visual system and vehicle information of a vehicle; according to the vehicle condition information and the vehicle information, whether the interference vehicle shields the zebra crossing is judged, and then feedback control is generated; comprising a brake system module for receiving a control command of the master control system to control a brake to perform deceleration operation within a specified distance. The traffic accident caused by the fact that a high-speed driving vehicle collides with pedestrians suddenly appearing on the zebra crossing under the condition that the zebra crossing exists in the front and an interference vehicle on the left side or the right side shields the sight line of a driver and the zebra crossing is effectively avoided, and the pedestrians outside the vehicle are further protected against the risk that the high-speed driving vehicle collides with the pedestrians.
Description
technical field [0001] The present invention relates to a vehicle anti-collision control system, in particular to a vehicle control system based on a vision system where the line of sight of a zebra crossing blocks a pedestrian's anti-collision. Background technique [0002] In recent years, the number of automobiles in my country has increased significantly, resulting in a sharp increase in traffic pressure and a sharp increase in the frequency of accidents. After investigation and analysis of the traffic accident data, it is found that the following traffic accidents have a certain proportion: when there is a zebra crossing in front of the vehicle, the driver is paralyzed and careless due to the stopped interfering car blocking one end of the zebra crossing, passing the zebra crossing at high speed, and colliding with the sudden pedestrians collided, resulting in a tragic traffic accident. The main cause of the accident is that the distance between the vehicles passing th...
