Description

A kind of anti-collision system and automobile in rainy weather

【Technical field】

The utility model belongs to the technical field of automobiles, in particular to an automobile anti-collision system in rainy weather and an automobile.

【Background technique】

At present, people are doing more and more researches on vehicle anti-collision technology in smog days, but there are very few studies on vehicle anti-collision technology in rainy days. The road is wet and slippery in rainy days. With the swinging process of the windshield wipers, the driver's sight is blocked, and it is impossible to predict the distance between the front and rear vehicles in advance and take timely braking and deceleration measures, resulting in frequent traffic accidents.

【Content of utility model】

In order to solve the problems existing in the prior art, the purpose of this utility model is to provide a car collision avoidance system and a car in rainy days. The utility model makes judgments on weather conditions and vehicle speed matching through rainfall monitoring, thereby reducing traffic accidents caused by car collisions in rainy days. ACCIDENT.

The purpose of this utility model is achieved through the following technical solutions:

A car collision avoidance system in rainy weather, including a rain gauge for monitoring the amount of rain, a vehicle speed sensor for measuring the speed of a vehicle, a rangefinder for detecting the distance between the front and rear of the vehicle body, a prompt unit for prompting and a device for receiving and processing rain The central processing unit that collects data from the meter, vehicle speed sensor and range finder and sends prompt instructions to the prompt unit.

The rain gauge is an ultrasonic rain gauge.

The range finder is a laser radar range finder.

The prompt unit is a voice alarm and/or an LED display.

A kind of automobile, described automobile is provided with anti-collision system in rainy days, the rain gauge of anti-collision system in rainy days is arranged on the roof or the sunroof position, and the vehicle speed sensor is arranged on the front wheel and/or rear wheel position of the automobile, and is arranged on the front of the automobile. Range finders are installed at the car and the rear of the car, and the prompt unit is set in the cab of the car.

The prompt unit is a voice warning device installed in the cab or an audio device in the car.

The prompt unit is an LED display or a vehicle-mounted video player arranged in the cab.

Compared with the prior art, the utility model has the following beneficial effects:

The utility model monitors the rainfall outside the vehicle through the rain gauge, the vehicle speed sensor measures the vehicle speed, and the range finder detects the distance between the front and rear of the vehicle body. The vehicle distance information between vehicles is transmitted to the central processing unit for processing. The central processing unit matches and judges the rainfall, vehicle speed and vehicle distance information. When the monitored rainfall and vehicle distance do not match the current vehicle speed, the central processing unit sends a notification When a prompt command is issued, the prompt unit prompts the driver with vehicle speed and vehicle distance information, and the driver performs braking and deceleration behavior according to the prompt information of the prompt unit. Therefore, the utility model can reduce traffic accidents caused by car collisions in rainy days and ensure driving safety in rainy days.

Further, the prompting unit is a voice warning device and/or an LED display, and the voice warning device is an external horn or an audio equipment provided by the vehicle body; the LED display needs to be installed independently for vehicles without a vehicle-mounted video player, and those with a vehicle-mounted video player Vehicles can be omitted.

【Description of drawings】

Fig. 1 is the structural representation of the automobile of the present utility model;

Fig. 2 is the structural block diagram of the rainy weather automobile anti-collision system of the present utility model.

Among them, 1-ultrasonic rain gauge, 2-vehicle speed sensor, 3-lidar speedometer.

【detailed description】

Below in conjunction with accompanying drawing, the utility model will be further described.

As shown in Figure 1 and Figure 2, the rainy day automobile anti-collision system of the present utility model includes the ultrasonic rain gauge 1 for monitoring rainfall, the vehicle speed sensor for measuring the speed of a vehicle, and the laser radar ranging for detecting the distance between the front and rear of the vehicle body Instrument 3, a prompting unit for prompting and a central processing unit for receiving and processing the data of the rain gauge, vehicle speed sensor and rangefinder and sending a prompting instruction to the prompting unit, the prompting unit is a voice warning device and/or an LED display, The various devices are connected by wire harnesses.

When the rainy car anti-collision system of the present utility model is installed on the car, the ultrasonic rain gauge 1 of the rainy car anti-collision system is arranged on the roof or the sunroof position, and the vehicle speed sensor 2 is arranged on the front wheel and/or rear wheel position of the car. LiDAR rangefinders 3 are installed at the front and rear of the car, and the voice warning device is an external speaker or the audio equipment that comes with the car body; the LED display needs to be installed independently for vehicles without a car video player, and there is a car video player The vehicle with the machine can be omitted.

The vehicle speed sensor detects whether the current vehicle speed is overspeed and corresponds to the current weather conditions in real time. The ultrasonic rain gauge monitors the amount of rain and transmits it to the central processing unit through the wiring harness. If the monitored rainfall does not match the current vehicle speed, the voice alarm will be triggered to remind the driver and perform braking and deceleration behavior. At this time, the LED display will dynamically display the current distance between vehicles in real time.
