Suspend engine work when lamp or traffic congestion, when the starting that vehicle experiences driver is intended to, quick start is started
Machine.Start stop system can effectively reduce idling oil consumption in city operating mode, reduce the discharge of automobile harmful gas.
Intelligent start/stop technology strengthens battery, the endurance life of starter, increase sensing in existing vehicle technical foundation
Device, control strategy exploitation and data mark are re-started to EMS (Engine ManagementSystem engine management systems)
It is fixed, to realize that engine is quickly shut down/started.
Vehicle start-up and shut-down control strategy is by EMS centralized Controls, in order to ensure engine shutdown and the security started and comfortably
Property, status signal that EMS is sent according to vehicle sensor and associated appliance module control engine start/shutdown.
The engine of equipment start stop system needs frequent starting, and about 600A electric currents are produced when starter works to be dragged down moment
The voltage of Full Vehicle System, the frequent starting of engine add the too low risk for bringing EMS/TCU to restart of vehicle voltage.In start and stop
In the design of system, prior art is used for steady using integrated ICR (surge current control relay) or vehicle increase DC-DC module
Determine the voltage of vehicle power supply.
ICR relays cut down peak point current by the current-limiting resistance that is delayed, and voltage drop when starter starts are reduced, so as to drop
Low-load terminal voltage drops, and voltage stabilizing is in the claimed range of setting.
Due to the frequent starting of engine, start and stop starter is used as simple execution unit always, also just increases its burning
Probability is lost, especially because the starter transmission mechanism that brings of consumable accessory engine flywheel ring gear damage is stuck or engine ignition system
During failure of uniting.
For upper description problem, solution known for inventor is to increase fuse protection on starter major loop, is used
To prevent vehicle or the personal injury that starter ablation is brought.Increase fuse protection on the starter major loop, refer in brush
Fusing breach is opened in the other parts that brush bridge or starting current flow through, after electric current exceedes setting for a period of time, is produced with itself
Raw heat makes breach fuse, so as to reach the purpose of protection.
Program major defect is that the moment of resistance is dynamic value, electric current needed for starter in starter dragging engine process
Fluctuation range is big, and it is larger that the size of breach defines limitation；And the engine of different qualities needs to define different opening sizes,
Increase manufacture and the part management cost of part.
Utility model content
The purpose of this utility model is overcome the deficiencies in the prior art, there is provided a kind of security monitoring of automobile starting/stopping system
System, the monitoring protective effect of complete coupled engines, starter while reducing management and cost of implementation to reach.
To achieve these goals, the technical solution adopted in the utility model is：A kind of safety prison of automobile starting/stopping system
Control system, including ICR relays, power supply is connected to form starter performance loop after ICR relays with starter, described
Delayer is provided with ICR relays；Described delayer is single-chip microcomputer, and described single-chip microcomputer pin is connected to starter and worked back
Lu Zhong, for the voltage in acquisition circuit；Described single-chip microcomputer is connected with EMS, and described EMS is connected with ignition system.
Described EMS is connected with entire car controller, and described entire car controller is connected with automobile instrument or vehicle-carrying display screen.
Described entire car controller is connected with alarm.
The AD pins of described single-chip microcomputer are connected in starter performance loop.
Described single-chip microcomputer is connected by signal wire or CAN with EMS.
The utility model has the advantage of：1st, by microcomputer monitoring starter performance loop inside ICR relays
Voltage, when voltage occurs abnormal, stop the startup of engine, so as to protect the purpose of engine and start stop system；2nd, simultaneously
And inform driver by sending alarm signal to automobile instrument, vehicle-carrying display screen, alarm；3rd, implementation is simple, cost is low, can
It is high by property, it is convenient to promote.

Embodiment
Below against accompanying drawing, by the description to optimum embodiment, specific embodiment of the present utility model is made into one
Step detailed description.
Referring to Fig. 1, to use the start stop system schematic diagram of ICR relays in the prior art, ICR relays are surge current
Control relay, the input of 12V plant-grid connections to electromagnetic switch, electromagnetic switch are connected with ICR relays, ICR relays with
Starter is connected, and starter connection power cathode is simultaneously grounded, so that power supply is connected to be formed after ICR relays with starter
Starter performance loop, ICR relays are used to driving the startup of starter, and the delayer inside ICR is used to be delayed.
In the preferred embodiment of the application, the delayer in ICR relays uses chip microcontroller, single-chip microcomputer
AD pins are connected in the performance loop of starter, and for the voltage data in acquisition circuit, the communications pins of single-chip microcomputer pass through
Signal wire is connected with engine management system EMS, and engine management system EMS is connected with ignition system.
Because single-chip microcomputer internal clocking can realize the effect of timing, on the basis of ICR relay functions are met, pass through
It is used to gather starter operating voltage in the A/D pins connection starter performance loop of single-chip microcomputer, A/D pins pass through wire here
It is connected to the input side or outlet side of starter in starter performance loop.A/D conversion chips connection A/D in the single-chip microcomputer draws
Pin is used to voltage signal being converted to data signal.Single-chip microcomputer according to magnitude of voltage judge now starter performance loop voltage whether
Normally, if the abnormal control signal that sends is into EMS, automotive ignition system is controlled to prevent engine from opening without igniting by EMS
It is dynamic, so as to reach the purpose of protection.Rule of judgment can be the main circuit voltage value of detection less than the threshold values set or be less than
Set threshold values and continue more than 0.3s, then judge that performance loop voltage is abnormal, EMS forbids ignition switch to light a fire.Now illustrate,
Starting current is larger, it is impossible to is started.
In a preferred embodiment, EMS is connected with entire car controller, and entire car controller connects car-mounted display respectively
Screen, alarm.When EMS forbids ignition system fires, control signal is simultaneously emitted by into entire car controller, by entire car controller
Control vehicle-carrying display screen and alarm to show fault message respectively and send alarm signal, remind human pilot detection event in time
Barrier.For showing that the vehicle-carrying display screen of fault-signal can also carry out display fault-signal using vehicle-mounted automobile instrument.EMS passes through
Monitoring and analysis to feedback signal, if continuing to start or stopping and result is fed back into vehicle by automobile instrument makes
User, to realize the communication of start and stop starter and vehicle, reach the purpose protected to starter and starting system.
Obvious the utility model specific implementation is not subject to the restrictions described above, as long as employing the methodology of the present invention
The improvement of the various unsubstantialities carried out with technical scheme, within protection scope of the present invention.
