Abstract

The utility model discloses a theft-proof and anti-hijacking controller for vehicle. The utility model is exclusively used for the theft-proof and anti-hijacking alarm system of an advanced intelligent vehicle, so that the utility model belongs to a device which can implement the forced decelerating operation for vehicle. The utility model comprises an instruction system circuit board and a relay 15; a power supply uses 12V automobile power supply; the utility model also comprises a wire bag 12 or a stepping electric machine 16; an electromagnetic valve 13 comprises a valve body 2, a valve core 3, a spring 5, and a valve seat 6; the inner part of the valve seat 6 is provided with an oil passing through pipe 10; the valve core 3 is communicated with the oil passing through pipe 10; the circular surface of the communicated part of the valve core 3 is provided with a groove; when the automobile is stolen in vehicle flameout state or when the vehicle is hijacked in process of driving, a driver can press an anti-hijacking key on a circuit board, or can press the anti-hijacking key on a remote controller, or can send out the anti-hijacking signal in telephone paging way. The oil path of an electromagnetic valve 13 can be in the flow limiting state to stop most of fuel oil from passing through; running of an engine can be maintained by a fraction of fuel oil flowing the small groove 9, so that vehicle only can be slowly driven in limited speed and can not be driven rapidly. Thus, a robber can not drive the vehicle to escape.

Description

The anti-theft control setup of vehicle electrical intercept form

The anti-theft control setup of vehicle electrical intercept form, be to be exclusively used in the anti-isolated plant of robbing warning of CBS series high-grade intelligent automobile burglar to vehicle implementation forced deceleration, to strengthen the anti-theft function of automobile, especially the anti-function of robbing can realize in the anti-misfortune process of automobile under the continuous electric situation of oil-break not automobile being carried out the device of forced deceleration.

At present, intermittent injection formula speed controller is arranged abroad, can allow the fuel charger intermittent injection, progressively prolong break time, engine oil is progressively reduced, the speed of a motor vehicle progressively reduces; Shortcoming is:

(1) control accuracy of time variation, chopper frequency requires height, and the control method complexity is difficult to grasp; Simultaneously, also high to the stability requirement of electric signal, realize that difficulty is big, easy break-down in service, poor reliability, instream factor is not high;

(2) be only limited to EFI formula driving engine and be suitable for, carburetion formula driving engine is then inapplicable.

The purpose of this utility model be to provide a kind of simple and easy to do, be easy to control, good stability, the anti-theft control setup of vehicle electrical intercept form of dependable performance arranged.

Technical characterictic:

The anti-theft control setup of vehicle electrical intercept form, it is characterized in that: the coil leading-out end of relay 15 is respectively circuit card control signal joint 1 and grounded terminal 2, a normally open contact 3 of relay 15 is power connector end, another contact 4 of relay 15 connects the line bag 12 of electromagnetic valve 13, another contact of line bag 12 connects ground wire terminal, line bag 12 is fixed on valve body 2 ends of electromagnetic valve 13, valve body 2 is with valve seat 6 usefulness screw threads or send out blue the connection, spool 3 be placed in the valve body 2 and with valve body 2 free-running fits, spring 5 is put in the spool 3, oil-through hole 10 1 ends in the valve seat 6 are communicated with joint 8, oil-through hole 10 other ends are communicated with joint 1, spool 3 passes through mutually with oil-through hole 10, passes through part spool 3 circular surfaces mutually and establishes one or more grooves 9.

Principle of work: Fig. 1-4, during use, the anti-theft control setup of vehicle electrical intercept form is installed on the automotive engine front end transport pipe, joint 8 connects fuel-tank outlet 11, joint 1 connects driving engine 14, the coil connectors 1 junction circuit plate of relay 15, and joint 2 connects ground wire, normally open contact 3 power connection positive poles, another contact of line bag 12 connects ground wire.See accompanying drawing 2, the oil transportation amount of electromagnetic valve 13 energy control oil channel is to realize the forced deceleration function and the speed limit function of automobile; Its working forms shows as two kinds of mode of operations of forward and back of spool:

(1) when start, the instruction repertoire circuit card sends an electrical signal to relay 15, and 3,4 pin of relay 15 are connected, have electric current to pass through in the line bag 12 of electromagnetic valve 13, produce magnetic field force, magnetic field force overcomes retracing spring power, attract spool 3 at the bottom of the valve, oil circuit is opening state.Oil circuit is unimpeded, the fuel oil of supply engine abundance, thus vehicle can be run at high speed at full capacity.

(2) after parking of automobile is flame-out, the instruction repertoire circuit card is not sent out work order, promptly there is not electric signal to be issued to relay 15 from instruction repertoire, relay 15 quits work, be off-state, supply current can not enter electromagnetic valve 13, do not have electric current to pass through in the line solenoid valve bag 12, magnetic field force disappears, and spool 3 is advanced into the valve top under the effect of retracing spring power, promptly enter in the valve seat oil-through hole 10, oil circuit is limited current state, stops most of fuel oil to pass through, and has only the little part fuel oil that flows through from minor groove 9 to keep the driving engine operation, vehicle can only be travelled in the speed that limits, and can not fast running.

When automobile was robbed under steam, the driver pressed the anti-misfortune key on the circuit card, or the anti-misfortune key on the remote controller, or the phone paging sends the anti-signal of robbing, and repeated above-mentioned limited current state.Vehicle slowly stops, and unlikely collision or overturning guarantee driver's safety.The burglar can not drive away their vehicles.

Characteristics of the present utility model:

1, control program is simple and direct, not high to the stability requirement of electric signal, is easy to realize system's good operation stability;

2, the forced deceleration process that automobile is anti-when robbing, safety, reliable has been eliminated effectively and variously may have been caused accident factors such as overturning, traffic jam, brake failure.

3, greatly promoted the anti-theft feature of vehicle self, not only made common cartheft be difficult to automobile is stolen,, also be difficult at short notice automobile be stolen even be proficient in the professional cartheft of automobile circuit.

4, be widely used in adopting the automobile of all types of driving engines that comprise carburetion formula and EFI formula.Manufacturing process is simple, and is with low cost, is easy to accomplish scale production.
