Description

The invention belongs to the field of motoring and relates to the circuitry ensuring complete control of the operation of the brake lights of cars from the driver's place.

S & No.__s

Many cars in road traffic do not have a brake light control. It is always possible to make sure that they are correct before the start, because after the activity has been pressed, the driver is required by the decree. This many times is not at all a brake pedal the driver himself does not see if both brake lights flash, and is not always close to a person who could help the light can fail to release the bulb by oxidizing the contacts, check the brake lamps. Also when driving the operation of the pressure brake switch, brake light, loss of contact by shock, or burning of the filament or both filaments of light - Situations that then arise in traffic when cars with limited brake light operation - only one light is on or both fail - there is no need to describe separately. In favorable cases, they lead to great stress for drivers driving behind such a car, and in more unfavorable cases an accident may occur, often with

tragic consequences.

Some types of cars hurt in the past - equipped with a warning light to alert the driver of the correct operation of the pressure brake switch. There have also been some brake light control connections, but they have the disadvantage that they interfere with the wiring of the car's brake lights by the necessary addition of different inductive sensors, electromagnets, relay windings, and the like.

Does the above-mentioned shortcomings in the essential mission remedy these? The brake light function monitor of a car according to the invention, wherein the first terminal of the integrated circuit is connected to the second contact of the brake light pressure switch and at the same time to one end of the resistance. The second IC circuit is connected to the first contact of the stop lamp bulb and the third IC circuit is through the first wiring to the braking conductor and the light resistor connected to the first terminal of the transistor and one end of the second resistance. Its other end is grounded and is connected to a second contact of the stop light bulb, a third transistor terminal and a second diode terminal. The first terminal of the diode is connected to the second end of the third resistor and at the same time to the second terminal of the transistor. ,

The main advantage of the wiring according to the invention is that it allows the car directly from its location behind the wheel at every instant visual inspection of the correct operation of the brake cars. a pressure switch for the brake lights and wiring leading to the switches by means of a light-emitting diode located in its field of view on the instrument panel of the automobile. A further advantage is that the wiring according to the invention can be simply retrofitted to an automobile without interfering with its braking system.

The enclosed drawing is a block diagram of an electrical wiring of a controller according to the invention. As shown in the accompanying drawing, the circuit according to the invention consists of an integrated circuit JUD whose first terminal 21 is connected to the second contact Q2. a pressure switch T1 of the brake lights and at the same time to one end of the third resistance R3. The stop light bulb 2 is connected by its first contact 1.1 to the second terminal 22 of the integrated circuit 10, wherein the second bulb ion 12 of the second resistor B2, i1. The second end of the second resistor R2 is connected to the first terminal 31 of the transistor I and at the same time through the first resistor R1 to the third terminal 22 of the integrated circuit 10. The first terminal 41 of the diode Q is connected to the second terminal 22 of the transistor Tas by the second end of the third resistor 52. If the brake light pressure switch T1 and the brake light bulb 2 are operating correctly, the light emitting surface of the diode Q lights up each time the brake light bulb 2 is lit. After the light bulb 2 goes out, the light emitting surface of the diode Q also goes off. or by loss of the galvanic connection to the wiring in contacts 11.12 brake light bulb 2 brake light bulb 2 does not light up when the brake light pressure switch TI is connected, which is good, the light-emitting surface of diode D when connected and disconnected Off. In such a case, however, the brake switch T1 lights that the brake light bulb 2 at the time the connected contacts are diode D does not light. If the brake light pressure switch T1 fails or the wiring leading to it is interrupted and the brake light bulb 2 cannot light, diode Q does not light at all.
