As domestic economy develops at a high speed, infrastructure is frequently carried out in various places, and overloaded trucks and engineering vehicles frequently come and go, the road surface is prone to be uneven, and road surface pits or depressions are frequently generated. In rainy days, water accumulated on the road surface is easily formed, and at the moment, if pedestrians, battery car drivers, motorcycle drivers and bicycle riding personnel exist nearby the water accumulated, the water accumulated when the vehicles run through splashes can cause the pedestrians, the battery car drivers, the motorcycle drivers and the bicycle riding personnel to be wetted by water, and unnecessary troubles, complaints and even disputes are caused. In recent years, civilized driving has been proposed in the country, and therefore, if each driver can drive a vehicle while taking pedestrians and electric vehicle drivers into consideration, the theme of the civilized society is also satisfied. However, through investigation, many drivers often pass through the water accumulation road surface at a high speed without slowing down the speed to avoid splashing because they only concentrate on safe driving and do not consider the experience of battery car drivers, motorcycle drivers, cyclists and pedestrians on both sides of the road. If the road surface accumulated water anti-splash braking device is available, the problems and disputes can be effectively reduced.

Drawings
FIG. 1 is a block diagram top view of an apparatus for a water accumulation splash guard of the present invention;
fig. 2 is a schematic view of the water accumulation splash guard of the present invention.
In the figure: 1. a vision device 2-3, a millimeter wave radar 4, a main control device 5, a brake device module 6 and a CAN network.
Detailed Description
The utility model is described in further detail below with reference to the figures and the embodiments.
As shown in fig. 1, the specific implementation includes a vision device 1, which takes an image of a road in front of a vehicle, identifies accumulated water through the image, and sends the image to a master control device through a CAN network 6;
the system comprises millimeter wave radars 2 and 3, detects the pedestrian distance on two sides of a vehicle, and sends the pedestrian distance to a master control device through a CAN (controller area network) 6;
the system comprises a main control device 4, a CAN network 6, a brake device module and a vision device, wherein the main control device receives the accumulated water of the vision device 1 and the distances of pedestrians of millimeter wave radars 2 and 3, generates feedback control to the brake device module according to the accumulated water and the distances of the pedestrians, and sends a control instruction;
the vehicle braking system comprises a braking device module 5 which is arranged in a vehicle, receives a control command from a main control device 4 to control a vehicle brake to perform speed reduction operation within a specified distance, and brakes in advance before accumulated water reaches to avoid splashing water and splashing pedestrians when the accumulated water passes through a road surface.
The vehicle information of the host vehicle is transmitted from the vehicle computer to the main control device 4.
The vision device 1 is disposed on the upper portion of the windshield of the vehicle and faces the road ahead, and millimeter wave radars 2, 3 are mounted on both sides of the body of the vehicle.
The complete implementation working process of the utility model is as follows:
as shown in fig. 2, the vision device installed in front of the vehicle may recognize the accumulated water in front, and in such a scene, if the vehicle passes through the accumulated water at a high speed, a traffic accident in which the vehicle hits a pedestrian suddenly may occur. When the scene appears, the vehicle speed needs to be reduced to a preset specified value in time, so that when an existing person suddenly appears on the accumulated water, a driver or an AEB can brake the vehicle to avoid colliding with pedestrians.
The millimeter wave radars 2-3 installed on both sides of the vehicle CAN recognize the distance to the pedestrian around the vehicle, thereby monitoring the surrounding vehicle conditions and transmitting the pedestrian information data to the main control device 4 through the CAN network 6 in real time.
In the emergency situation, if the driver does not take effective measures due to cognitive delay or improper operation, the device main control unit 4 immediately judges whether the speed needs to be reduced or not according to the pedestrian distance obtained by the millimeter wave radar 2-3 in time, then reminds the driver and starts to take over the vehicle through a prompt warning signal, then the device starts to monitor the speed reduction intention of the driver, and once the driver starts to reduce the speed, the device starts to give up the take-over vehicle, converts the speed reduction intention into a steering control instruction according to the current vehicle speed and sends the steering control instruction to the braking device module 5 through the CAN network 6.
If the vehicle needs to be decelerated, a braking instruction is sent to the vehicle body stability control module ESC through emergency braking avoidance to enable the braking device module to perform emergency braking, and the vehicle is guaranteed to pass through the ponding road surface at a preset target low speed. The braking device module 5 controls a braking device according to a given control instruction, so that the vehicle is controlled to a reasonable speed when the vehicle reaches a safe distance before water accumulation.
After finishing the emergency deceleration action, the main control device 4 will quit the control and remind the driver to take over the steering wheel of the vehicle again to continue normal driving.
