It is relatively low that active force on flywheel ring gear end face can reduce, and effectively reduces flywheel ring gear and drives gear
The wear extent of end face, thus ensure that the reliability that starter is durable.
Below in conjunction with the control flow chart of the starter of Fig. 5 first embodiment of the invention, it is discussed in detail and rises
The work process of motivation, as shown in the flowchart, after key door switch 35 connection (step S110), electronics
The Logic control module 221 controlling device begins through voltage sense line 225 detection control power supply terminal
The voltage (step S121) of 50c, when detecting that the voltage controlling power supply terminal 50c is more than or equal to setting
Value U1 (during electrical power generators, regulator output voltage is that 27.8 ± 03V, U1 are set as 27.5V),
Then judging that electromotor is working, control unit 2214 controls the first power tube Q1 and is not turned on (step S123),
So it is possible to prevent the starter reignition caused due to driver's maloperation, thus causes driving gear to break
Tooth.When control power supply terminal 50c voltage being detected less than U1, the control list of Logic control module 221
Unit 2214 controls the first power tube Q1 and turns on (step S122), the power supply terminal 30 of such electromagnetic switch
Electric current flowed in sucking coil 36 and the hold-in winding 37 of electromagnetic switch 3 by the first power tube Q1,
Gear 6 is driven to get towards flywheel ring gear 10 under electromagnetic switch produces the effect of electromagnetic force, also due to electric
The resistance of magnetic switch sucking coil is smaller, and motor can drive the driving little moment of torsion of gear to rotate, and drives gear
Start to carry out flexible engagement with flywheel ring gear.
After the first power tube Q1 reaches the time T1 of setting conduction time, as T1 is set to 0.1～0.3s,
Logic control module 221 detects the voltage (step of the input terminal 30b of motor by voltage sense line 223
Rapid 13), in order to judge that electromagnetic switch contact is closed the most, i.e. indirectly judge whether drive gear
Engaging-in engine flywheel gear ring, when the power supply of voltage and the electromagnetic switch of input terminal 30b motor being detected
The pressure drop of terminal 30 is more than the value Δ U set, or the voltage≤U3 of the input terminal 30b of motor, then sentence
Power-off magnetic switch contact is not closed, the power supply terminal 30 of electromagnetic switch contact electromagnetic switch and the input of motor
Terminal 30b does not turns on, and i.e. drives gear not realize engaging with flywheel ring gear, then control unit 2214 controls
Second power tube Q2 turns on (step 142), then electric current passes through current limliting from the power supply terminal 30 of electromagnetic switch
Resistance 224 flows to the input terminal 30b of the motor of electromagnetic switch, thus flows into motor.Same current-limiting resistance
The resistance of 224 is smaller, similar to electromagnetic switch sucking coil resistance, and such motor can produce a step
Property moment of torsion, thereby may be ensured that the moment of torsion of generation can allow driving the smooth engaging-in gear ring of gear, it might even be possible to
The flywheel ring gear under resting state is allowed to rotate.If be detected that the electricity of the input terminal 30b of electromagnetic switch motor
Pressure is less than the value Δ U set, or the input terminal of motor with the pressure drop of the power supply terminal 30 of electromagnetic switch
The voltage of 30b is more than U3, then judge that electromagnetic switch contact achieves Guan Bi, i.e. drives gear and flywheel teeth
Circle has been realized in engagement, and Logic control module 221 will not allow the second power tube Q2 turn on, and continues control
Make the first power tube Q1 and turn on (step 146), owing to electromagnetic switch contact there occurs that Guan Bi, electromagnetism are opened
Close sucking coil 36 will be shorted, only by electric current, such first power tube in hold-in winding 37
The electric current passed through in Q1 will reduce to tens amperes, the most several amperes.Also due to contact occurs
Guan Bi, the electric current in accumulator 13 directly will flow to motor 1 by electromagnetic contact, and starter can be greatly
Moment of torsion exports, and starter starts to start electromotor.
After car by electromotor, the load of starter diminishes, and the voltage controlling power supply terminal 50c can rise.
During so starting, Logic control module 221 detects control power supply by voltage sense line 225
Terminal 50c voltage (step S161), when detecting that control power supply terminal 50c voltage exceedes setting voltage
U2 (as U2 is set to 24 ± 0.3V), the first power tube Q1 end (step S163), and electromagnetic switch is broken
Electricity, starter quits work, and so can shorten the working time of starter.If be detected that control power supply
Terminal 50c voltage is always less than the voltage U2 set, and control unit 2214 allows the first power tube Q1 continue
Conducting (step S162), until timing module 2213 detects that the first power tube Q1 ON time reaches
Setting time T4 (as set T4 as 22～30s), controls the first power tube Q1 and ends (step S200),
Thus allow electromagnetic switch contact disconnect, drive gear to release engine flywheel gear ring, starter quits work.
When under some abnormal conditions, as driven gear and flywheel ring gear gear pair assembling existing problems etc., the
The time T2 that conduction time time of two power tube Q2 conductings reaches to set is (during now power tube Q1 conducting
Between reach T3=TI+T2) after, Logic control module detects the input of motor by voltage sense line 223
The voltage of sub-30b, if be detected that the input terminal 30b voltage of motor and the power supply terminal of electromagnetic switch
30 voltage drop are more than the value Δ U set, or the voltage≤U3 of the input terminal 30b of motor, then judge
Electromagnetic switch contact is not closed, and the power supply terminal 30 of electromagnetic switch does not turns on the input terminal 30b of motor,
I.e. drive gear not with flywheel ring gear realize engage, then control unit 2214 control the first power tube Q1 with
Second power tube Q2 ends (step S1440～step S153), and electromagnetic switch attracts and hold-in winding breaks
Electricity, starter quits work, such that it is able to prevent the starter apical tooth caused due to abnormal cause, i.e. drives
Gear cannot engaging-in gear ring, ultimately result in solenoid winding, current-limiting resistance and function pipe burning fault send out
Raw.
Second embodiment:
In some cases, such as engine at extreme rear, the voltage drop controlling circuit is bigger, so, controls electricity
Source terminal 50c and the extreme pressure drop distribution scope of accumulator positive are bigger, for 24V system, have very
To having reached more than 2V.So controlled the voltage swing of power supply terminal 50c by detection, starter is entered
Row controls, by inaccurate or do not have the effect of being effectively protected, even to start opposite effect.As surmounted protection
Magnitude of voltage arranges too small, and on the vehicle that pressure drop is smaller, starter is also not fully complete starting, and Electronic Control fills
The defencive function put just works, and starter is forced to force power-off.When line drop is bigger, starter
Control the voltage of power supply terminal 50c it would be possible to always less than arranging voltage, starter surmount defencive function
May forever not have effect.
For the problems referred to above, the present invention also been proposed another scheme, due to the power supply terminal of electromagnetic switch
30 compare thick and comparatively short with the connection wire of accumulator positive inter-stage, the power supply terminal 30 of such electromagnetic switch
Pressure drop will be smaller, by the voltage of power supply terminal 30 of detection electromagnetic switch, starter is carried out many
Planting protection control will be more accurate.
Present embodiment is compared with embodiment one, and the overall structure of starter is basically identical, as shown in Figure 6,
The soft engaging starter of step includes being sequentially connected with electronic-controlled installation 22, electromagnetic switch 3 and motor 1, electronics
Control device 22 to be connected by a control power supply terminal 50c and an accumulator 13, accumulator 13, electromagnetism
Switch 3, motor 1 same as the prior art, electromagnetic switch 3 include sucking coil 36, hold-in winding 37,
The power supply terminal 30 of electromagnetic switch and the input terminal 30b of motor.The present embodiment is at the base of embodiment one
Eliminate voltage sense line 225 on plinth, add voltage sense line 222, the first voltage acquisition module
22111 are connected with the power supply terminal 30 of electromagnetic switch by voltage detecting circuit 222, the second voltage acquisition
Module 22112 is connected with the input terminal 30b of motor by voltage detecting circuit 223.
Below in conjunction with the control flow chart of Fig. 7, briefly introduce starter worked of the present embodiment
Journey, after key door switch 35 connection (step S110), Logic control module 221 begins through voltage inspection
The voltage (step S121) of the power supply terminal 30 of electromagnetic switch is detected on survey line road 222, when electromagnetism being detected
The voltage of the power supply terminal 30 of switch is more than or equal to value U1 (as U1 is set as 27.5V) set, then
Judging that electromotor works, control unit 2214 controls the first power tube Q1 and the second power tube Q2 not
Conducting (step S123), starter energising is reactionless, is so possible to prevent owing to driver's maloperation causes
Starter reignition, drive the fault such as gear tooth breakage such that it is able to reduce.
When power supply terminal 30 voltage of electromagnetic switch being detected less than U1, control unit 2214 controls the
One power tube Q1 turns on (step S122), and the electric current of the power supply terminal 30 of such electromagnetic switch is by the
One power tube Q1 flows in sucking coil 36 and the hold-in winding 37 of electromagnetic switch 3, drives gear at electricity
Get under the effect of magnetic switch generation electromagnetic force, owing to the resistance of electromagnetic switch sucking coil is smaller, motor
The driving little moment of torsion of gear can be driven to rotate.
After the first power tube Q1 reaches the time T1 (such as 0.1～0.3s) of setting conduction time, logic control
Module 221 detects the voltage (step S13) of the input terminal 30b of motor by voltage sense line 223,
So that judging that electromagnetic switch contact is closed the most, i.e. indirectly judge to drive the most engaging-in electromotor of gear
Flywheel ring gear, when the power supply terminal 30 of voltage and the electromagnetic switch of input terminal 30b that motor detected
Pressure drop is more than the value Δ U set, or the voltage≤U3 of the input terminal 30b of motor, then judge that electromagnetism is opened
The power supply terminal 30 closed is not closed with the input terminal 30b of motor, i.e. drives gear unreal with flywheel ring gear
Now engage, then control unit 2214 control second power tube Q2 turn on (step S142), then electric current from
The power supply terminal 30 of electromagnetic switch flows to the input terminal of the motor of electromagnetic switch by current-limiting resistance 224
30b, thus flow into motor.Owing to the resistance of current-limiting resistance 224 is smaller, for 24V starting system,
Resistance is about 70～200mohms, and for 12V starting system, resistance is about 20～100mohms, so
Can be by the electric current of a step evolution in motor, same motor can produce the moment of torsion of a step evolution, thus can
To ensure that the moment of torsion produced can allow the driving smooth engaging-in gear ring of gear, it might even be possible to allow flying under resting state
Wheel gear ring rotates.
When the voltage of input terminal 30b motor being detected is little with the pressure drop of the power supply terminal 30 of electromagnetic switch
In the value Δ U set, or the voltage of the input terminal 30b of motor is more than U3, then judge that electromagnetic switch is touched
Point achieves Guan Bi, i.e. drives gear to have been realized in engaging with flywheel ring gear, and control unit will not allow the
Two power tube Q2 conductings, continue to control the first power tube Q1 and turn on (step S146), owing to electromagnetism is opened
Closing contact and there occurs Guan Bi, the sucking coil 36 of electromagnetic switch 3 will be shorted, only hold-in winding 37
In by electric current, the electric current passed through in such first power tube Q1 will be reduced to tens amperes, even only have
Several amperes.Also due to contact there occurs Guan Bi, the electric current in accumulator 13 will directly pass through electromagnetism
Switch contact flows to motor, and starter can export by high pulling torque, and starter starts electromotor.
When under some abnormal conditions, as driven gear and flywheel ring gear gear pair assembling existing problems etc., the
The time T2 that conduction time time of two power tube Q2 conductings reaches to set is (during now power tube Q1 conducting
Between reach T3=TI+T2) after, Logic control module detects the input of motor by voltage sense line 223
The voltage of sub-30b, if be detected that the input terminal 30b voltage of motor and the power supply terminal of electromagnetic switch
30 voltage drop are more than the value Δ U set, or the voltage≤U3 of the input terminal 30b of motor, then judge
Electromagnetic switch contact is not closed, and the power supply terminal 30 of electromagnetic switch does not turns on the input terminal 30b of motor,
I.e. drive gear not with flywheel ring gear realize engage, then control unit 2214 control the first power tube Q1 with
Second power tube Q2 ends (step S1440～step S153), and electromagnetic switch attracts and hold-in winding breaks
Electricity, starter quits work, such that it is able to prevent the starter apical tooth caused due to abnormal cause, i.e. drives
Gear cannot engaging-in gear ring, ultimately result in solenoid winding, current-limiting resistance and function pipe burning fault send out
Raw.
After electromotor starts, the load of starter diminishes, the power supply terminal of the electromagnetic switch of electromagnetic switch 3
The voltage of 30 can rise.During so starting, Logic control module 221 passes through voltage sense line
The voltage of the power supply terminal 30 of 222 detection electromagnetic switch, when power supply terminal 30 electricity electromagnetic switch being detected
Pressure exceedes setting voltage U2 (by a large amount of test data analysis, it is proper that U2 is set to 24 ± 0.3V),
Control the first power tube Q1 and end (step S163), electromagnetic switch power-off, starter quits work, this
Sample can shorten the working time of starter.If be detected that power supply terminal 30 voltage of electromagnetic switch is always
Less than the voltage U2 set, Logic control module allows the first power tube Q1 continue conducting (step S162),
Until timing module 2213 detects that the first power tube Q1 ON time reaches setting time T4 (as set
T is 22～30s), control the first power tube Q1 and end (step S200), thus allow electromagnetic switch contact
Disconnecting, drive gear to exit engine flywheel gear ring, starter quits work.
For different starter application, the resistance of the current-limiting resistance 224 in electronic-controlled installation 22 is permissible
Design more easily, do not limited by other factors such as the hold-in winding numbers of turn.Current-limiting resistance 224 can also set
Meter, in electromagnetic switch 3, as coil, is wound on above skeleton；Also can design outside starter,
As being designed to a wire, connect the input of the second power tube Q2 outfan and the motor of electromagnetic switch 3
Sub-30b.Current-limiting resistance can select the bigger material of resistivity ratio to make, such as constantan, rustless steel etc..
For different customer demands, above-mentioned defencive function can be shielded, as disconnected each voltage sense line,
May be reduced by corresponding defencive function；The parameter of each defencive function above-mentioned can be adjusted according to customer demand
Whole.
