Abstract

The utility model discloses a control system for a far-reaching headlight and a dipped headlight of an automobile. The control system comprises a power supply, a power supply switch, a detector, a microprogrammed control unit (MCU) circuit, an emergency illuminance circuit, the far-reaching headlight, the dipped headlight, an automatic controller and a manual switching switch, wherein the power supply is connected with the automatic controller by a resistor (R1) and a resistor (R2); the automatic controller consists of a far-reaching headlight controller and a dipped headlight controller; the far-reaching headlight controller is connected with the far-reaching headlight, and the dipped headlight controller is connected with the dipped headlight; the MCU circuit is connected with the detector, the automatic controller and the manual switching switch (K3) respectively; and the emergency illuminance circuit (K2) is connected in parallel at two ends of the far-reaching headlight controller. The control system switches the far-reaching headlight and the dipped headlight automatically during meeting, so that the using method of the far-reaching headlight and the dipped headlight accords with traffic rules during the meeting, and the safety of driving at night is improved; and the emergency illuminance circuit can be turned on artificially under the emergent condition.

Description

A kind of automobile dimming-distance light lamp control system

Technical field

The utility model relates to a kind of automobile dimming-distance light lamp control system, belongs to technical field of automotive electronics.

Background technology

Cars meeting at night, require both sides driver at a distance of about 150 meters apart from the time close mutually country beam switched to passing light, but usually have driving new hand to forget that on the road surface far and near lamp switches; Or because the laziness of chaufeur; Switch lamp not according to traffic regulation, when mutual meeting, caused one section vision blind area; When on the road surface encumbrance being arranged, will cause traffic accident.

The utility model content

The purpose of the utility model provide a kind of can the relative operating range of detection at any time front vehicles, can carry out automatic guidance and switch with manual control long-and-short distant light, can manually boot the automobile dimming-distance light lamp control system of emergency lighting.

For achieving the above object; The improved RE valve of the utility model adopts following technical scheme; A kind of automobile dimming-distance light lamp control system; Comprise power supply, source switch, detector, MCU circuit, emergency lighting circuit, country beam, passing light, auto mat and MTS, said power supply links to each other with auto mat with resistance R 2 through resistance R 1; Said auto mat is made up of country beam controller and passing light controller, and the country beam controller links to each other with country beam, and the passing light controller links to each other with passing light; The MCU of institute circuit links to each other with detector, auto mat and MTS K3 respectively; Said emergency lighting circuit K2 constitutes, and is connected in parallel on country beam controller two ends.

As preferably, described detector is a car radar.

As preferably, described MCU inside circuit timer was to passing light controller ON time regularly 10 seconds.

As preferably, described country beam controller and passing light controller are made up of relay.

As preferably, described manual mode controller links to each other with the interrupt pin of MCU circuit.

As preferably, said auto mat is made up of relay and MCU circuit jointly.

As preferably, described detector distance is set at 150 meters.

The beneficial effect of the utility model is: the utility model automobile dimming-distance light lamp control system is when meeting; Automatically performing long-and-short distant light switches; Can the people be the conversion of carrying out far and near lamp also, far and near light uses and meets traffic regulation when guaranteeing meeting, improves the night travel safety; Simultaneously under urgent situation, unlatching emergency lighting circuit that can be artificial.

The specific embodiment

See also Fig. 1 and Fig. 2; A kind of automobile dimming-distance light lamp control system; Comprise power supply 121, source switch K1, detector 222, MCU circuit 111, emergency lighting circuit K2, country beam 161, passing light 171, auto mat 151 and MTS K3, said power supply 121 links to each other with auto mat 151 with resistance R 2 through resistance R 1, and said auto mat 151 is made up of country beam controller and passing light controller; Closed source switch K1; Circuit defaults country beam controller is opened, and the country beam controller links to each other with country beam 161, and the passing light controller links to each other with passing light 171; Said detector 222 records front vehicles relative distance numerical value real-time and that MCU circuit 111 is set and compares in real time; The data that record when said detector 222 are less than recording when setting numerical value; Auto mat 151 is opened the passing light controller; Close the country beam controller, said MCU circuit 111 timer internals regularly; The MCU of institute circuit 111 links to each other with detector 222, auto mat 151 and MTS K3 respectively; Said emergency lighting circuit K2 is connected in parallel on country beam controller two ends; When the system failure appears in circuit, can be artificial carry out enforced opening country beam 161.

Wherein, described detector 222 is a car radar; Described MCU circuit 111 timer internals were to passing light controller ON time timing 10 seconds; Described country beam controller and passing light controller are made up of relay; Described MTS K3 links to each other with the interrupt pin of MCU circuit 111, and when MTS K3 pressed, circuit produced and interrupts, and switches to passing light 171 to country beam 161; Said auto mat 151 is made up of relay and MCU circuit 111 jointly; Apart from control relay switch and closure, described detector 222 distance settings are 150 meters to MCU circuit 111 according to detector 222.

The utility model automobile dimming-distance light lamp control system is when meeting; Automatically performing long-and-short distant light switches; Can the people be the conversion of carrying out far and near lamp also, far and near light uses and meets traffic regulation when guaranteeing meeting, improves the night travel safety; Simultaneously under urgent situation, unlatching emergency lighting circuit that can be artificial.

The above is merely the specific embodiment of the utility model, but the protection domain of the utility model is not limited thereto, and any variation or replacement of expecting without creative work all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with the protection domain that claims were limited.
