Automotive safety systems are mainly divided into two aspects, one is the active safety system, the other is the passive safety system. The role of active safety is to avoid accidents, which determines the probability of automobile accidents. In order to prevent automobile accidents, improve the driving stability of automobiles, and prevent people from being injured, people pay more and more attention to active safety precautions and early warning systems in the prior art, such as high-position brake lights, front and rear fog lights, and rear glass window defogging. Light, ABS, EBD, TCS and other functional modules. In addition to the control and processing of collisions and vehicle speeds, it is also necessary to use advanced vehicle active safety systems to detect the driver's driving behavior, tire condition, vehicle speed, vehicle distance, visual blind spots and other information through various sensors. Make corresponding warning actions and take necessary safety measures. In addition, as consumers' requirements for the safety, stability, comfort and other performance of automobiles continue to increase, the performance of automotive electronic products is also constantly improving.

In order to achieve the above object, the utility model adopts the following technical solutions:

A smart car active safety early warning system, including a microprocessor, a vehicle navigation module connected with the microprocessor for reading the longitude and latitude of the current position, and can provide real-time navigation functions for car drivers, and also includes The following modules connected to the microprocessor:

Alcohol measurement and control module to measure the alcohol concentration in the air in the current car;

An identity confirmation module for identification by means of security anti-theft keys, input of security passwords, etc.;

A video acquisition and detection module to monitor whether the driver is driving fatigued;

The temperature measurement and control module that measures the temperature inside and outside the car through the temperature sensor inside and outside the car;

Anti-collision warning module;

Adaptive cruise module that automatically maintains a safe distance from the vehicle in front;

A night vision auxiliary module that automatically senses the influence of ambient light around the vehicle and performs automatic identification and judgment;

Panoramic image module.

The microprocessor is an embedded microprocessor.

The tire pressure measurement and control module is connected with the built-in sensor arranged on the tire to measure and control the tire pressure of the automobile. When the tire pressure is lower than the standard value and there are danger signs, the tire pressure measurement and control module will alarm in time and take safe braking operation to avoid tire blowout during high-speed driving. The driver can monitor in real time through the prompt warning system in the car to judge whether the tire pressure is normal. In this way, it can effectively avoid driving deviation due to tire deflation, and at the same time, it is also a guarantee for the safety of passengers when driving at high speed.

The anti-collision warning module can automatically detect the distance to the vehicle in front, monitor the road environment ahead, vehicles and the distance between vehicles, and use technical means to analyze driving environment information such as the condition of the lane and surrounding vehicles. The module is linked with the vehicle's braking, lighting and other systems. When the following distance is lower than the safe distance, the system will start within a few milliseconds to forcefully increase the following distance. When it is detected that the vehicle may collide, it will warn the driver of the vehicle. Once the collision is unavoidable, the automatic braking system is activated immediately. During emergency braking, the hazard warning lights will flash automatically to remind the vehicles behind as soon as possible to prevent rear-end collisions. This module can also increase the brake oil pressure assistance according to the driver's braking force, so that the braking action can be completed as soon as possible, and the vehicle speed can be reduced to a safe speed. At the same time, the pre-collision system will quickly close the windows, tighten the seat belts, fix the driver and passengers in the best position of the seat, so that the airbag can play the best function; adjust the position of the headrest to prevent the neck injury of the occupants. In terms of pedestrian protection, when components such as radar, infrared or image sensors sense that the vehicle body is about to collide with pedestrians, the pre-collision system will urgently notify the driver. When a collision is unavoidable, the vehicle activates the automatic braking system and the airbags located on the bumper and the front windshield to reduce the damage to the pedestrian's head, chest and feet.

The night vision auxiliary module includes devices such as automatic induction headlights, infrared headlights, laser night vision lane departure warning devices, and thermal imaging cameras. The infrared camera is located on the inside of the windshield and is connected to the display on the instrument panel of the cockpit. When the light is not enough and the sight is not clear at night or in rainy and foggy weather, the infrared technology is used to enable the driver to see farther and more clearly in the dark. Using the night vision assist device, the driver can see in advance the traffic signs, curves, pedestrians, cars, lost goods or other dangerous things on the road in the dark where the low beam cannot be illuminated. In this way, the driver can take braking or avoidance measures in time. The headlights of Night Vision Assist operate outside the wavelength range of visible light and therefore do not interfere with human vision.

The panoramic image module includes a front grille, left and right side exterior mirrors and a camera installed on the tailgate, and the camera is connected with the display screen of the driver's cab. Through the real-time viewing of the camera, the images collected by the camera are displayed on the display screen of the cab to provide the driver with relevant environmental information in blind spots. For people, vehicles, and objects in the blind spot, the front/rear radar will warn the driver when detecting obstacles to give visual and auditory warnings. The embedded microprocessor processes the image signal, and then extracts the necessary signal. By analyzing the edge portion of the image, vehicles and lanes ahead can be detected. With road detection, an alert can also be issued for lane departures.

The adaptive cruise module locks the target vehicle in front through license plate ranging and laser ranging methods, and calculates the movement information of the vehicle in front, such as vehicle speed, acceleration, yaw rate, etc., and then based on the calculated distance and relative speed and other information, further calculate the safe distance between the two vehicles, and make acceleration and deceleration actions according to this standard, and always automatically maintain a safe distance from the vehicle in front. When the distance between the two vehicles is too close and the adaptive cruise module detects that there may be a crisis, it will send out a warning signal in due course and automatically switch to the vehicle's pre-collision processing mode. In this way, the danger caused by the driver's negligence or unskilled driving can be reduced during driving, and automatic driving can be completed.

The interface of the vehicle navigation module of the real-time navigation function displays the data of the current latitude and longitude, and the system automatically retrieves the map according to the received GPS data, and displays the current position on the panel.

The temperature measurement and control module compares the measured temperature with the preset value. If the limit value is exceeded, the window will be automatically opened or closed at the right time, and the air conditioner will be turned off or turned on to adjust the temperature, so as to provide the driver with a comfortable driving environment, so as to avoid anxiety and anxiety. Affect driving and cause hazards. Especially, it has extremely important safety significance for drivers and passengers sleeping in the car or having accidental shock.
