Description

 The invention relates to electrical equipment of vehicles, namely to control systems for rear fog lamps of a car.

 Known control systems of fog light sources on vehicles containing fog lights, a central outdoor light switch, a fog light switch and a fog lamp ON relay (see, for example: Reznik A.M. Electrical Equipment of Cars. M .: Transport, 1990, p. 213-215, 240-243).

 A disadvantage of the known control systems is the low efficiency of controlling the rear fog lamps, since using them does not achieve the required sequence of turning on / off the rear fog lamps depending on the switching on / off of other lighting sources on the vehicle, for example, headlights or side lights, and Thus, the necessary road safety is not ensured.

 The closest analogue of the claimed technical solution is the control system of the rear fog lamps of the car, which includes the rear fog lights, after turning on the headlights or after turning on the front fog lights (VAZ-2110, -2111, -2112 cars. Maintenance and repair manual. - M .: Driving, 1999, p. 136), containing rear fog lights, a central light switch, a front fog lamp switch, a rear fog lamp switch and a front fog lamp relay, while the contact of the central light switch, including the side lights, is connected to the rear fog lamp switch and the front fog lamp switch, and the output contact of the rear fog lamp switch is connected to the rear fog lamps.

 The disadvantage of this rear fog light control system is that when it is used, the driver's rear fog light switch left (forgotten) in the on state will turn on the rear fog light when the vehicle lights up again, for example, headlights or side lights, which is unacceptable for traffic safety requirements. In addition, the continuous combustion of the lamps of the rear fog lamps is not ensured when the lighting mode is switched by the central light switch and when the headlamps are switched from low to high beams.

 Based on this drawback, the task to which the claimed technical solution is directed is to increase the efficiency of controlling the rear fog lamps of the vehicle, which increases traffic safety.

 Improving the control of the rear fog lamps of the vehicle is achieved by the fact that the control system of the rear fog lamps, comprising rear fog lights, a central light switch, a front fog lamp switch, a rear fog lamp switch and a closing relay of the front fog lamps, the contact of the central switch lights, including side lights, connected to the rear fog light switch on and off the front fog lamp, and the output contact of the rear fog lamp switch is connected to the rear fog lamps, contains a closing relay for locking the rear fog lamps, an opening relay for controlling the winding of the closing relay for locking the rear fog lamps, the rear fog lamp switch is equipped with three contacts, the front fog lamp switch the headlight is made with two pairs of contacts, the central light switch is made three-position, controlling the winding of the opening relay of the control relay of the winding of the closing relay of the rear fog lamp lock is connected to the contact of the central light switch connected to the "plus" of the vehicle circuitry in the position of the central light switch "turning on the winding of the opening relay of the control relay of the winding relay of the locking relay of the rear fog lamp", the control contact output windings of the closing relay for locking the rear fog lamps connected to the input terminal of the opening relay the winding of the closing relay for locking the rear fog lamps and through the constantly open output contact of the opening relay for controlling the winding of the closing relay for the vehicle with a minus circuit of the vehicle, the input terminal of the control winding of the closing relay for locking and its power contact are connected to each other and through the switch for the rear fog lamps located in the "turn off the rear fog lamp" position, through the diode with the contact of the central light switch, off sensing the headlamps in the “headlamps on” position, and with the first pair of contacts of the front fog lamp switch, the output of the permanently open contact of the closing relay for locking the rear fog lamps is connected to the “plus” of the vehicle electrical circuit, the contacts of the closing relay of the front fog lamps and three the input contacts of the central light switch are connected to the "plus" of the vehicle electrical circuit, the control winding of the front fog lamp relay the second pair of contacts of the front fog lamp switch is connected to the contacts of the central light switch, which are switched on in the positions "turning on the headlights" and the position "turning on side lights".

 The technical result from the use of the proposed technical solution is that the rear fog lights can only be turned on after turning on the headlamps or front fog lights. In addition, turning on and off the rear fog lights can only be done while the side lights are on. In this case, the fog lights will go out after the side lights are turned off automatically and will not turn on after they are turned on when the rear fog lamp switch is left (forgotten) in the on state.

 Another technical result from the use of the proposed technical solution is to ensure the continuity (without blinking) of the combustion of the rear fog lamps when the lighting mode is switched by the central light switch and when the headlights are switched from low to high beam, which is ensured by the presence of a closing relay to lock the rear fog lamp and opening relay control winding closing relay rear fog lamp lock. With stable burning of lamps (without blinking), their service life increases.

 The drawing shows a control circuit of the rear fog lamps with its individual elements, each of which is depicted as a circuit diagram.

 The rear fog lamp control system contains rear fog lamps 1, a rear fog lamp switch 2 with three contacts 3, 4, 5, which is connected to the rear fog lamps 1 via contact 3, front fog lamps 6, a closing relay 7 of the front fog lamps 6 s contacts 8, 9, 10, which is connected to the front fog lights 6 through contact 9, and the switch 11 of the front fog lights 6, which is made with two pairs of contacts: 12, 13 and 14, 15 and connected via contact 13 to clock 8 of the closing relay 7. The control system for the rear fog lamps also includes a closing relay for locking 16 (RB) of the rear fog lamps 1, which is equipped with an input 17 and output 18 contacts of its control winding and power contacts 19 and 20. The control system of the rear fog lamps also contains the winding control relay (CBM) 21 of the closing RB 16 of the rear fog lamps 1, which is equipped with an input terminal 22, a continuously closed output terminal 23 and a terminal 24. In the control system The rear fog light also includes a central light switch 25, which is equipped with contacts 26, 27, 28, 29 and input contacts 30, 31, 32 and is made three-position with the following positions: “turning on the winding of the disconnecting CBM 21 of the closing RB 16 of the rear fog lamps 1”, "inclusion of headlights of head light" and "inclusion of marker lights". The control winding of the disconnecting CBR 21 is connected via pin 24 to the terminal 26 of the central light switch 25, which is connected to the "plus" of the vehicle electrical circuit at the position of the central light switch 25 "turning on the CBR winding 21 of the closing RB 16 rear fog lamps 1". The output contact 18 of the control winding of the closing RB 16 is connected to the input contact 22 of the disconnecting CBR 21 and through the continuously closed output contact 23 of the opening CBR 21 with the minus of the vehicle circuitry. The input contact 17 of the control winding of the closing RB 16 and its power contact 20 are interconnected and through the switch 2 of the rear fog lamps 1, which is in the "off rear fog lights" position, through the diode 33 with the contact 27 of the central light switch 25, including the headlights 34 in the position "turning on the headlights", and with the first pair of contacts 14 and 15 of the switch 11 of the front fog lamps 6. The output is a permanently open contact 19 of the closing RB 16 of the rear fog lamps 1 a "plus" electrical vehicle. The permanently open contact 10 of the closing relay 7 of the front fog lamps 6 and the input contacts 30, 31, 32 of the central light switch 25 are connected to the "plus" of the vehicle electrical circuit. The control winding of the closing relay 7 of the front fog lights 6 through pin 8 and contacts 12, 13 of the switch 11 of the front fog lights 6 is connected to the contacts 28 and 29 of the central light switch 25, which are turned on in the "turn on headlights" position and on the "turn on side lights" "

 The control system of the rear fog lamps works as follows. When the rear fog light switch 1 is turned on by a switch 1, current is supplied to them from the "plus" of the vehicle electrical circuit through a fuse (not shown) from the central light switch 25 only after the closing RB 16 is activated. The control winding of the closing RB 16 is energized from contacts 4 and 5 switch 2 of the rear fog lamps 1, the current to which is supplied either from terminal 15 of the switch 11 of the front fog lamps 6 when they are turned on or through the diode 33 from terminal 27 of the central light switch 25, turn-on headlamps 34. As a result of connecting contact 18 of the closing RB 16 and contact 22 of the disconnecting ROW 21 of the closing RB 16 and contact 24 of the control winding of the CBR 21 with contact 26 of the central light switch 25, connected to the "plus" of the vehicle wiring in the "on" position windings of the disconnecting CBR 21 of the closing RB 16 ", to the disconnecting CBR 21 of the closing RB 16, until the side lights are turned on, constant power is supplied. In this case, the disconnecting CBR 21 of the closing RB 16 disables the winding of the closing RB 16 and the rear fog lamps 1 cannot be turned on. After turning on the side lights, front fog lights 6 or headlights 34, the disconnecting CBR 21 of the closing RB 16 is de-energized and connects the output terminal 18 of the control winding of the closing RB 16 through its input terminal 22 and through its permanently closed output terminal 23 to the "minus" of the transport circuitry facilities. The closing RB 16 is triggered by closing the contacts 19 and 20, and supplies power to pin 5 of the rear fog lamp switch 2, switch 1. The switch 2 is set to the "rear fog lamp activation" position. The rear fog lights 1 are turned on, while the voltage is supplied to the control winding of the closing RB 16 and it remains on regardless of whether the headlights 34 or the front fog lights 6 are turned on or off. After turning on the headlights 34 and the side lights, the central light switch 25 translates it to the position "turning on the winding of the opening CBR 21 of the closing RB 16" the opening CBR 21 of the closing RB 16 is activated, opens the contacts 22 and 23, the winding of the closing RB 16 is disconnected, the contacts 19 and 20 open Xia, the power supply circuit for the rear fog lamps 1 is broken, the lights 1 are turned off and cannot be turned on until they are connected again by turning on the central light switch 25 and switch 2 of the rear fog lamps.

 The proposed rear fog lamp control system can be installed and used on vehicles equipped with front fog lamps, and not equipped with them, as well as having one or two rear fog lamps.

 When using the proposed system, the operation of the rear fog lamps of the vehicle is fully compliant with the requirements of UNECE Regulation 48.01 and the conditions of certification.
