Description

Technical field

The technical solution relates to a device for determining a safe distance from the rear of a vehicle, with the intention of creating an advanced part of the modern transport safety system used in today's cars, ie for use in the automotive industry and transport.

BACKGROUND OF THE INVENTION

At present, one of the essential elements in cars, trucks, motorcycles and other means of transport or equipment is brake lights, which alert drivers of rear-end vehicles that they are braking and then decelerating. Usually, when the driver in an emergency depresses the brake pedal, the brake light comes on and, if fitted, the third brake light comes on. This is done to alert the driver at the rear to be cautious as the vehicle brakes in front of him and then slows down. However, if the car in the front suddenly approaches a car from the rear, the driver behind the next vehicle will hardly find out how much the safety risk is for both the driver and himself by driving too close to him. Although there are means to warn drivers that they drive too close and do not maintain a safe distance between vehicles, they are not always effective enough.

The essence of the technical solution

To solve these problems, there is a device for determining a safe distance from the rear of the vehicle according to this solution, which alerts the driver behind him that he is too close to the front of the car and represents a significant threat. The advantage of this solution is an improved, more advanced and safer road and motorway environment. At the same time, it improves and adds additional safety features to vehicles. The device according to this solution is an electronic system which serves to increase the safety of cars on roads and highways in situations when the driver approaches the car in front of him at a dangerous distance. The safety system was designed to prevent rear-end collisions. The device detects if the vehicle is behind it at a dangerous distance. The system can also take into account driving conditions and calculate the safety distance according to the detected conditions (driving conditions: fog, drizzle, rain, damp, wet snow, hail, ice rain and others).

A device for determining the safe distance from the rear of the vehicle shall consist of a radar, sensors or camera located at the rear of the vehicle with a signal and used to monitor and evaluate the traffic situation behind the vehicle; a third stop lamp located at the rear of the vehicle between two stop lamps; Stop lamps located at the rear of the vehicle to give a visual warning to the driver at the rear and from a logic unit connected to the third stop lamp (s) and registering the vehicle speed and driving conditions, the device may be fitted with a hazard warning or auxiliary lamp.

Overview of the figures in the drawing

In the picture no. 1 is a schematic illustration of a device for determining a safe distance from the rear of a vehicle; and FIG. 2 shows the principle of determining the safety distance.

Example of technical solution

The device according to this solution uses radar 2, sensors 2 or cameras 2 to monitor the traffic situation behind the vehicle. Using these elements, the system assesses the conditions behind the vehicle as a potential risk, then the third brake light 3 or the brake lights 4 connected to the LUN will start to visually alert the rear vehicle driver that he is too close to the front vehicle and should slow down. As soon as the driver of the rear vehicle is away from the danger distance 7 from the front vehicle, the third stop lamp 3 or the stop lamps 4 return to their off or original state. Pushing the brake pedal overrides the operation of this device and the third brake light 3 or brake lights 4 behave as in normal or emergency braking situations. The logic unit I registers the vehicle speed as well as driving conditions (such as fog, drizzle, rain, damp, wet rain, hail, ice rain or other) from other sensors 5 to accommodate the transmission of radar 2 or sensor 2 to a safe distance 7.

The system is automatically activated at speeds above 30 km / h (this value may be lower or higher). Optionally, the system can be turned off by a button on the instrument panel or the central control panel.

Stop lamps 4 or third stop lamp 3 need not flash. The light may dim and glow to create an illusion of flicker during braking. During braking, only the light intensity changes.

Under dangerous conditions behind the vehicle, the device shall evaluate these conditions and change the behavior of the third stop lamp (s) 4 (including or excluding stop lamps 4, hazard warning lamps or auxiliary lamp 6 as follows:

The lights are on or flashing

The lights dim and then glow

The lights are on or flashing in a certain pattern

The lights will change color if multicolour LEDs are used.

The transmission of radar 2 or sensor 2 is automatically adapted to the current vehicle speed (the higher the speed, the greater the safety distance 7 between the two vehicles must be observed). In addition, the system is automatically deactivated at lower speeds.

An auxiliary lamp or a filament lamp 6 may be integrated into the device at the rear of the vehicle. lamps or filament lamps which emit light. The device can be used in vehicles with built-in radar 2, sensors 2 or camera 2, but also in vehicles without parking sensors or radar by placing sensors or radar and after placing sensors or radar in vehicles.

The device monitors the traffic situation behind the vehicle by means of sensors 2, camera 2, parking sensors, radar sensors 2, ultrasonic technology or other already existing in-vehicle systems that can assess the situation and send data to the post-processing device.

Other options for alerting the rear vehicle driver if it is too close to the front vehicle are:

- the intensity of the lights varies and allows the lights to become brighter or faster to illuminate the driver of the rear vehicle.

- multi-color light-emitting diodes can be used, which means the system can use orange-colored LEDs instead of standard red-colored LEDs.

other colors or colored lights such as orange or red may also be used.

Industrial usability

The object of the invention can be used in transport and in the automotive industry, having the advantages of preventing or minimizing short-term, long-term injuries or death to car occupants present in a car accident where the collision was caused by another vehicle moved to the rear of the car. and sets new safety standards in cars and other vehicles, saves expensive car repairs in the event of an accident where one car runs into the back of another vehicle due to a poor estimate of how close the car was in front of it and effectively improves road safety.
