Technical Field

the invention belongs to the field of automobile control automation, and particularly relates to an automobile brake lamp system based on a sensor.

Background

At present, vehicles are increasingly put into use all over the world, but due to the limitation of physiological characteristics of drivers, automatic deceleration braking cannot be implemented every year, and a great deal of life and property loss is caused by braking delay such as tire burst and rear-end collision. In order to reduce accidents and reduce life and property losses, more automatic intelligent control technologies are urgently needed to automatically implement safety rescue and improve driving safety.

A vehicle brake system refers to a series of special devices that apply a certain force to certain parts of the vehicle (mainly the wheels) so as to apply a certain degree of forced braking thereto. The braking system has the following functions: the running automobile is forced to decelerate or even stop according to the requirement of a driver; stably parking a stopped vehicle under various road conditions (including on a slope); the speed of the vehicle running on the downhill is kept stable. The vehicle lamp plays an important role in driving safety as one of the most important accessories of the motor vehicle. For motor vehicles, the warning effect of the brake lights requires special attention.

modern automobiles are faster and faster in speed, the traffic flow density on roads is very dense, the distance between the automobiles exceeds the safe braking distance, and when the front automobile is emergently braked, a driver of a rear automobile determines whether to brake or not through a brake lamp of the front automobile. When the vehicle runs, a driver hardly notices whether the speed of the driver exceeds the speed limit range, so that the driver can brake to limit the speed in time. If the brake lamp of the front vehicle breaks down, serious traffic accidents can be caused, so that the brake lamp is very important in road driving. The existing vehicle brake lamp has no indicator lamp to display on an instrument or a multimedia display screen or perform prompt processing in addition, and if the brake lamp damages a vehicle owner and a vehicle behind, the vehicle owner and the vehicle behind cannot know the brake lamp, so that traffic accidents are easy to happen.

Disclosure of Invention

The invention provides an automobile brake lamp system based on a sensor, which can enable an automobile to detect potential safety hazards in advance in the driving process, and brake and decelerate and warn a rear coming automobile in advance.

The basic scheme of the invention is as follows: a sensor-based automobile brake lamp system comprises a positioning module, an inquiry module, an acquisition module, a database, a display module, a comparison module, a control module, a brake lamp and an alarm module;

the positioning module is used for acquiring positioning information of the position of the automobile and sending the positioning information to the query module;

The database is used for storing map information and speed limit information corresponding to the map, and the map information is a set of a plurality of positioning information;

The query module is used for receiving the positioning information sent by the positioning module, finding out corresponding speed limit information from a database according to the positioning information, and sending the speed limit information to the display module and the comparison module;

The display module is used for receiving the speed limit information sent by the display module and displaying the speed limit information;

The acquisition module comprises a speed sensor, and the speed sensor is used for acquiring the current running speed information of the automobile and sending the current running speed information to the comparison module;

the comparison module is used for receiving the current running speed information sent by the acquisition module and the speed limit information sent by the query module, comparing the current running speed information with the speed limit information, and sending warning information to the control module when the speed limit information is less than or equal to the current running speed;

The control module is used for receiving the alarm information sent by the comparison module and controlling the brake lamp to be lightened and the alarm module to be started.

The principle and the beneficial effects of the basic scheme are as follows: in the scheme, the running speed of the vehicle is monitored by combining the speed limit condition of the road, the alarm is given when the speed of the vehicle is too high, the driver is informed to decelerate in time, the brake lamp is lightened to remind the driver of coming the vehicle behind, and the vehicle can decelerate, so that the traffic accidents are reduced.

furthermore, the acquisition module also comprises a photosensitive sensor arranged near the brake lamp; when the control module receives the alarm information, the control module also controls the conduction of a circuit where the photosensitive sensor is located; the photosensitive sensor is used for acquiring the illumination intensity information of the brake lamp and sending repair information to the control module when the illumination intensity is lower than a preset minimum value of the illumination intensity; the control module is also used for receiving the repair information sent by the acquisition module, and controlling the display module to display the repair information and the alarm module to start.

Considering that the illumination intensity of the brake lamp is gradually reduced after the brake lamp is aged or broken down, so that whether the brake lamp of the front vehicle is in electric quantity or not is difficult to identify by a vehicle coming from the rear; in this scheme, when the stop lamp started, utilize photosensitive sensor response illumination intensity to in time remind the staff to repair and change the stop lamp.

further, the alarm module comprises a warning lamp and an alarm.

warning light and alarm are all installed in the automobile body, guarantee that the staff of driving position can discover to report to the police.

further, the display module is also used for displaying the current running speed information.

the scheme is favorable for workers to accurately master the vehicle running condition when driving the vehicle, and avoids traffic accidents.

Further, the device also comprises a communication module and a signal receiving module; when the control module controls the brake lamp to be turned on, the communication module sends brake information to the rear of the vehicle in the driving direction through the wireless network; the signal receiving module is used for receiving braking information sent in front of the vehicle running direction, calculating vehicle distance information between two vehicles and two-vehicle collision time information according to the braking information, and sending the vehicle distance information and the two-vehicle collision time information to the display module for displaying.

In this scheme, it is assumed that both the vehicle a and the vehicle B travel on the road, and the vehicle a travels in front of the vehicle B. When the control module of the vehicle A controls the brake lamp to be turned on, the communication module of the vehicle A sends brake information to the signal receiving module of the vehicle B, and the content of the brake information comprises the signal transmitting time of the vehicle A, the driving speed of the vehicle A and the brake acceleration of the vehicle A; after the signal receiving module of the vehicle B receives the braking information, the distance between the vehicle A and the vehicle B and the time when the vehicle A and the vehicle B collide with each other under the current trend can be calculated according to the signal transmitting time of the vehicle A, the driving speed of the vehicle A, the braking acceleration of the vehicle A, the driving speed of the vehicle B, the driving acceleration of the vehicle B and the signal receiving time of the vehicle B. In the scheme, the display module displays the vehicle distance information and the two-vehicle collision information, so that a vehicle driver can know the vehicle running condition conveniently, and the vehicle running safety is ensured.
