Description

An automatic control system for automobile headlights

technical field

The utility model relates to the technical field of automobiles, in particular to an automatic control system for automobile lamps.

Background technique

With the improvement of people's material living standards, more and more families have their own private cars. When driving a car, the driver needs to put all his energy on the steering wheel of the car, and danger may occur if he does not pay attention a little. Therefore, in many cases, the turn signal is turned on after reaching an intersection or making a turn and starting to stop in a line. There is no time for the car behind to react, and tragedies often happen like this. Turning on the turn signal can be said to be a kind of early warning, informing others of your own driving direction in advance, so that you can better avoid it, and it is also conducive to your own safe and fast driving. If the turn signal is not turned on when the car is turning, the possibility of traffic accidents is even greater. During the running of the car, the driver also needs to turn on the turn signal according to the situation while mastering the steering wheel. This operation is easy to distract the driver's attention and is inconvenient to use, especially for beginners.

Description of drawings

Fig. 1 is the structural representation of the utility model.

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

Detailed ways

Referring to Fig. 1, the automatic control system for automobile lights of the present utility model includes a sensor group, a microprocessor, an optical signal module and a solar power supply module, wherein the sensor group is connected with the microprocessor through an interface circuit, and the optical signal Both the module and the automobile turn LED light are connected with the microprocessor, and the solar power supply module supplies power for the microprocessor and the automobile turn LED light respectively.

The microprocessor adopts 89C51 single-chip microcomputer. The single-chip microcomputer is used to judge whether the azimuth change of the car is greater than a set value according to the received angular velocity detection signal and speed detection signal, and control the turning on and off of the turning LED light of the car according to the judgment result.

The sensor set includes a speed sensor and an ambient light sensor. Among them, the speed sensor is installed in the vehicle speedometer or arranged on the axle of the front bogie of the car. The speed sensor is used to collect the vehicle speed, and convert the speed detection signal into a signal accepted by the single chip microcomputer through the interface circuit and input it to the single chip microcomputer. The ambient light sensor is installed on the roof of the car, and the ambient light sensor is used to collect the intensity of ambient light, which prompts the microprocessor to control and adjust the brightness of the car's turn signal to further achieve the purpose of safe driving.

The optical signal module is installed on the roof of the car, and the optical signal module is used to send the angular velocity detection signal to the single chip microcomputer. The optical signal module adopts optical transmitter, optical receiver and optical transponder. The optical transmitter sends the optical signal, the optical transponder sends the turn signal to the optical receiver, and the optical receiver sends the received optical signal to the microcontroller.

The working principle of the utility model is as follows:

After the car is started, the optical signal module starts to detect the change of direction, and outputs optical signals with identification information of different angles. The optical signals are sent to the single-chip microcomputer, and the single-chip microcomputer judges whether to turn on the turn signal through calculation and comparison based on the received data. When it is detected that the change in the orientation of the car is greater than the set value, the corresponding turn signal is turned on in combination with the current speed. When it is detected and compared that the changed orientation of the car is smaller than the set value, it will automatically turn off the turn signal.
