Abstract
The utility model relates to the technical field of switching circuits for using an automobile control module to collect a brake signal, in particular to a duplex brake signal switching circuit which is preferably used for VE 83 light-duty Euro III automobile models. The duplex brake signal switching circuit comprises a power supply, a fuse, a normally open switch and a tail brake lamp, wherein one end of the power supply is electrically grounded; the other end of the power supply is electrically connected with the fuse; the other end of the fuse is electrically connected with the normally open switch; the other end of the normally open switch is electrically connected with the tail brake lamp; one end of the tail brake lamp is grounded; the fuse is electrically connected with the normally open switch; a normally closed switch is electrically connected with an ECU (Electronic Control Unit) controller; the normally open switch is electrically connected with the ECU controller; the ECU controller is electrically connected with a cruise control strategy module; and the ECU controller is electrically with a fault indicating lamp on an instrument. The duplex brake signal switching circuit can avoid the invalidation of the ECU control strategy function when one brake switching circuit is disconnected and becomes invalid.
Description
Technical field
The utility model relates to the switch circuit technical field that a kind of automobile control module is gathered speed-slackening signal, relates in particular to a kind of duplex brake lamp switch circuit, preferably uses in the light-duty Europe of VE83 three vehicles.
Background technology
The automobile brake on-off signal is important acquired signal in the automotive engine control module; Only be designed to one tunnel switch circuit in the past; Exist and break off the risk that lost efficacy; Engine control module can't be gathered speed-slackening signal like this, and the uncontrollable then correlation function that other needs this signal input to carry out is like cruising control, driving engine oil spout control etc.
Summary of the invention
The utility model provides a kind of duplex brake lamp switch circuit in order to overcome above-mentioned defective.
In order to realize the purpose of the utility model, the technical scheme that the utility model adopts is:
A kind of duplex brake lamp switch circuit comprises power supply, insurance; Normal open switch, tailstock brake lamp, said power supply one end is electrical ground; One end is electrically connected insurance, and the said insurance other end is electrically connected normal open switch, and the said normal open switch other end is electrically connected tailstock brake lamp; Said tailstock brake lamp one end ground connection, said insurance is electrically connected with normally closed switch, and said normally closed switch is electrically connected with the ECU controller; Said normal open switch is electrically connected with the ECU controller, and said ECU controller is electrically connected with the cruising control policy module, and fault-indicating lamp is electrically connected on said ECU controller and the combination instrument.
The beneficial effect of the utility model is:
Can avoid one road brake switch circuit to exist and break off the risk that lost efficacy; When being designed to two-way braking switch circuit, be exactly one the tunnel or two-way the time all in bad order, also can detect through the ECU controller; According to the timely bright fault-indicating lamp of storage failure code; Function is driven in restriction, reminds chaufeur in time to safeguard, avoids relative disabler risk.
Description of drawings
Accompanying drawing 1 is the electrical principle scheme drawing of the utility model.
The specific embodiment
Embodiment: with embodiment the present invention is further specified below in conjunction with accompanying drawing 1:
A kind of duplex brake lamp switch circuit comprises power supply 1, insurance 2; Normal open switch 3, tailstock brake lamp 5, an end of said power supply 1 is electrical ground; The other end of said power supply 1 is electrically connected an end of insurance 2, and the other end of said insurance 2 is electrically connected an end of normal open switch 3, and the other end of said normal open switch 3 is electrically connected an end of tailstock brake lamp 5; The other end ground connection of said tailstock brake lamp 5; One end of said insurance 2 is electrically connected with normally closed switch 4 one ends, and said normally closed switch 4 other ends are electrically connected with ECU controller 6, and said normal open switch 3 is electrically connected with ECU controller 6; ECU controller 6 is electrically connected with cruising control policy module 8, and fault-indicating lamp 7 is electrically connected on said ECU controller 6 and the combination instrument.
The utility model electrical principle is described below: the normal open switch 3 of coupled twin switch connects insurance 2 and ECU controller 6, is connected to tailstock brake lamp 5 simultaneously, and normally closed switch 4 also is connected to insurance 2 and ECU controller 6.Through being provided, a mixed signal of often opening (master control switch) and normally closed (secondary control switch) two-way gives ECU controller 6; The coupled twin switch of this circuit can have 4 kinds of on off states altogether: first kind: if normal open switch does not have closure; Normally closed switch does not break off; ECU controller 6 detection information are normal, and tailstock brake lamp 5 does not work.Second kind: if normal open switch is closed, normally closed switch does not break off, and ECU controller 6 detection information are fault; Tailstock brake lamp 5 is bright; ECU controller 6 will make the cruising control policy module lose efficacy, if ignition lock opens and closes more than 3 times simultaneously, ECU controller 6 control fault indicator lamps 7 are bright.The third: if normal open switch is closed, normally closed switch breaks off, and ECU controller 6 detection information are normal, and tailstock brake lamp 5 is bright, belongs to the normal brake application signal condition.The 4th kind: if normal open switch does not have closure, normally closed switch breaks off, and ECU controller 6 detection information are fault, and tailstock brake lamp 5 does not work, and ECU controller 6 will make the cruising control policy module lose efficacy.So just can ensure that the driver when sending speed-slackening signal, can unimpededly not hinder, tailstock brake lamp normally lights, and fault is arranged else if, can point out the driver through the utility model design circuit, presses failure condition restriction driving model simultaneously.
