The invention has a simple structure, can conveniently monitor the traffic lights of the road, remind the owner of the vehicle to stop or start in time, and reduce the occurrence of traffic violations.

Description

A kind of intelligent car driving warning system

technical field

The present invention relates to a vehicle control system.

Background technique

With the development of science and technology, cars have now become the means of transportation for the public, and the number of private cars has increased dramatically. Vehicles will encounter a large number of traffic lights when driving on urban roads. According to the current traffic rules, a vehicle running a red light will be severely punished. However, as a car owner, sometimes because of being distracted, he does not notice the change of the traffic light, causing a red light by mistake or failing to start the vehicle in time when the green light is on, which aggravates the traffic jam.

Contents of the invention

The purpose of this invention is to provide a smart car driving reminder system, which is used to monitor traffic lights and remind car owners to stop or start in time.

In order to achieve the above object, the following technical solutions are adopted: a smart car driving reminder system, characterized in that: the system includes a camera arranged at the center of the upper part of the front windshield of the car, and the camera is connected to the controller in the car through wires to control A voice alarm is also connected to the device through a wire;

The controller obtains the color of the front traffic lights through the camera. If the acquired image has only one color from the traffic lights, it will control the voice alarm to issue corresponding voice commands according to this color; if the acquired image has more than two colors from the traffic lights, Then, the voice alarm is controlled according to the color of the traffic light closest to the center line in the horizontal direction on the acquired image to issue corresponding voice commands.

The system also includes a brake light controller for controlling the brake light of the car. The brake light of the car has more than three independent LED lights arranged side by side. The number of lights, the greater the downward pressure, the more LED lights are lit.

The invention has a simple structure, can conveniently monitor the traffic lights of the road, remind the car owner to stop or start in time, and reduce the occurrence of traffic violations. At the same time, the system controls the size of the lighting range of the rear lights through the depression of the brake pedal, which can give appropriate reminders to the cars behind and reduce the occurrence of rear-end collisions.

Description of drawings

Figure 1 is a practical structural diagram of the present invention;

Figure 2 is a schematic diagram of the image captured by the camera;

Figure 3 is a schematic structural view of the tail brake light in the present invention.

Detailed ways

The present invention will be further described below in conjunction with accompanying drawing and specific embodiment.

As shown in Figure 1, a kind of smart car driving warning system, described system comprises the camera 2 that is arranged on the central position on the upper horizontal direction of automobile 1 front windshield glass, camera 2 is connected with the controller in the car by wire, and controller A voice alarm is also connected to the wire through the wire;

The controller obtains the color of the traffic light in front through the camera, and controls the voice alarm to issue corresponding voice commands.

There are two situations here:

1. When there is only one kind of car lane on the road, there is only one traffic light color on the image captured by the camera, which is one of blue, yellow or red. In this case, the controller can directly activate the voice alarm according to the color Give the corresponding voice command, such as "Attention Red", "Attention Yellow", or "Attention Red".

2. When there are two or all three car lanes between forward, left or right turn on the road, there are two or three colors of traffic lights on the image captured by the camera, which can be obtained according to the distance The color of the traffic light closest to the center line in the horizontal direction on the image is used for corresponding voice output, and the basis at this time is that the vehicle itself has turned into the corresponding vehicle lane. As shown in Figure 2, at this moment, controller just thinks that automobile is positioned at the left side automobile lane, is about to turn left, and the color of the traffic light at the center of the screen is determined to be the standard of judgment.

The system also includes a brake light controller that controls the brake light of the car. The brake light of the car has more than three independent LED lights arranged side by side. The brake light controller controls the independent LED lights in the brake light to light up according to the degree of depression of the brake pedal The greater the pressure, the more LED lights will be lit.

As shown in Figure 3, if the driver please press the brake pedal, only the LED light 3 in the middle of the brake light will be on. If the brake pedal is depressed to the bottom, all five LED lights will light up. In all the other cases, only the LED lights 3 and the LED lights 4 on both sides are on, and the LED lights 5 are extinguished.

This kind of brake light controller can effectively remind the rear car of its braking situation, so that the driver of the rear car can take appropriate measures to reduce the occurrence of rear-end collisions.

Claims (2)

1. A smart car driving warning system, said system includes a camera arranged at the center of the front windshield of the car, the camera links to each other with a controller in the car by a wire, and the controller is also connected with a voice alarm by a wire; The device obtains the color of the traffic light in front through the camera. If the acquired image has only one color of the traffic light, the voice alarm is controlled to issue corresponding voice commands according to the color; the feature is that: if the acquired image has more than two traffic lights According to the color of the traffic light closest to the center line in the horizontal direction on the acquired image, the voice alarm is controlled to issue corresponding voice commands. 2. The smart car driving warning system as claimed in claim 1, characterized in that: said system also includes a brake light controller which controls the brake light of the car, the brake light of the car has more than three independent LED lights arranged side by side, The brake light controller controls the number of independent LED lights in the brake light according to the depression range of the brake pedal.
