The utility model discloses an automobile tail lamp control system, which comprises a controller and a tail lamp driving circuit connected with the controller, wherein the tail lamp driving circuit and a tail lamp are used for controlling the work of the tail lamp; the key point is that the automobile tail lamp control system also comprises a distance sensor for detecting the distance between the rear vehicle and the automobile, and the distance sensor is connected with the controller. The control method of the automobile tail lamp control system comprises the following steps: in the driving process, the controller detects the distance between the rear vehicle and the vehicle in real time through the distance sensor, and when the distance between the rear vehicle and the vehicle is smaller than the preset distance, the controller controls the tail lamp to be lightened according to a first preset mode through the tail lamp driving circuit.
Description
Technical Field
The utility model belongs to the technical field of the car, concretely relates to automobile tail lamp control system.
Background
With the development of economy, the quantity of automobiles in China is getting larger and larger, and as shown by statistics, the quantity of motor vehicles in China is up to 3.4 hundred million, the quantity of automobiles is 2.5 hundred million, the number of motor vehicle drivers is 4.22 hundred million, and the number of the motor vehicle drivers is 3.8 hundred million as seen in 2019 by 6 months. With the increase of automobiles, automobile traffic accidents are more and more, and automobile rear-end collision is one of the most common traffic accidents. The most common cause of rear-end accidents of automobiles is that drivers of rear vehicles are not concentrated, and cannot keep a safe distance or brake in time.
Disclosure of Invention
The utility model aims at providing an automobile tail lamp control system can remind the back car driver through the tail lamp to reduce the emergence probability of rear-end collision accident.
The utility model discloses an automobile tail lamp control system, which comprises a controller and a tail lamp driving circuit connected with the controller, wherein the tail lamp driving circuit and a tail lamp are used for controlling the work of the tail lamp; the key point is that the automobile tail lamp control system also comprises a distance sensor for detecting the distance between the rear vehicle and the automobile, and the distance sensor is connected with the controller.
The control method of the automobile tail lamp control system comprises the following steps: in the driving process, the controller detects the distance between the rear vehicle and the vehicle in real time through the distance sensor, and when the distance between the rear vehicle and the vehicle is smaller than the preset distance, the controller controls the tail lamp to be lightened according to a first preset mode through the tail lamp driving circuit.
Further, the automobile tail lamp control system also comprises a vehicle speed sensor, and the vehicle speed sensor is connected with the controller. Correspondingly, in the control method of the tail lamp, during driving, the controller also obtains the speed of the vehicle through the vehicle speed sensor in real time, obtains the speed of the rear vehicle relative to the vehicle according to the speed of the vehicle and the change situation of the distance between the rear vehicle and the vehicle, and controls the tail lamp to be lightened according to a second preset mode through the tail lamp driving circuit when the distance between the rear vehicle and the vehicle is smaller than the preset distance and the speed of the rear vehicle relative to the vehicle is larger than the preset speed.
Further, this car tail lamp control system still includes car loudspeaker, car loudspeaker are connected with the controller. Correspondingly, in the control method of the tail lamp, the controller controls the tail lamp to be lightened according to the second preset mode through the tail lamp driving circuit, and meanwhile, the controller also emits the preset warning sound through the automobile horn.
The utility model discloses an automobile tail lamp control system utilizes the tail lamp to remind the rear-end car driver when rear-end car is too close with this car and have the danger of knocking into the rear, and when the danger of knocking into the rear is higher, combines sound to remind the rear-end car driver, thereby makes the rear-end car driver can notice the danger of knocking into the rear, increases with the vehicle distance of this car, reduces the possibility of knocking into the rear.
Drawings
Fig. 1 is a schematic diagram of the automobile tail light control system of the present invention.
Detailed Description
The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings, wherein the embodiments of the present invention are described in detail with reference to the accompanying drawings, for example, the shapes and structures of the respective members, the mutual positions and connection relationships between the respective portions, the functions and operation principles of the respective portions, and the like.
Example 1:
the embodiment provides an automobile tail lamp control system, which can remind a driver of a rear automobile through a tail lamp, so that the occurrence probability of rear-end accidents is reduced.
As shown in fig. 1, the automobile tail lamp control system of the present embodiment includes a controller, and a tail lamp driving circuit, a vehicle speed sensor, a vehicle horn, and a distance sensor for detecting a distance between a rear vehicle and the vehicle, which are respectively connected to the controller, and the tail lamp driving circuit is connected to the tail lamp to drive and control the operation of the tail lamp.
The vehicle speed sensor may be a radar mounted at a rear bumper of the vehicle.
The control method of the automobile tail lamp control system comprises the following steps: in the driving process, the controller detects the distance between the rear vehicle and the vehicle in real time through the distance sensor, acquires the speed of the vehicle in real time through the speed sensor, and then acquires the speed of the rear vehicle relative to the vehicle according to the speed of the vehicle and the change situation of the distance between the rear vehicle and the vehicle, and when the distance between the rear vehicle and the vehicle is smaller than the preset distance and the speed of the rear vehicle relative to the vehicle is smaller than or equal to the preset speed, the controller controls the tail lamp to be lightened according to a first preset mode through the tail lamp driving circuit; when the distance between the rear vehicle and the vehicle is smaller than the preset distance and the speed of the rear vehicle relative to the vehicle is larger than the preset speed, the controller controls the tail lamp to be lightened according to a second preset mode through the tail lamp driving circuit, and meanwhile, the preset warning sound is emitted through the vehicle loudspeaker.
The predetermined distance may be a fixed value, for example, 3 meters, or a value associated with the speed of the rear vehicle with respect to the host vehicle, and the predetermined distance may be larger as the speed of the rear vehicle with respect to the host vehicle is larger, for example, the predetermined distance = X5 seconds as the speed of the rear vehicle with respect to the host vehicle.
The predetermined speed may be a fixed speed value, for example, 10 m/s, or a speed value associated with the real-time vehicle speed of the host vehicle, for example, the larger the real-time vehicle speed of the host vehicle is, the smaller the predetermined speed is.
The first predetermined manner is to increase the brightness of the tail lamp, and the second predetermined manner is to increase the brightness of the tail lamp while flashing.
The present invention has been described in detail with reference to the accompanying drawings, and it is apparent that the present invention is not limited by the above embodiments, and various insubstantial improvements can be made without modification to the present invention.
