Specific embodiment
Fig. 1 shows the schematic diagram of onboard power system layout.For starter, such as 12V in this onboard power system layout
For gear starter, there is mechanical relay 119 on internal combustion engine 117, the relay of the machinery is removed in the axial direction
Pinion gear is and at the same time make the closing of circuit of starter motor.Wherein there is higher current peak.
Circuit of starter 107 is directly sandwiched on the anode of Vehicular battery 109 in the case where no electrical fuses, because
In this case due to higher electric current, fusible link is unsuitable.But there is high temperature fuses 121
(Pyrofuse), which can separate circuit of starter 107 and Vehicular battery 109 in mechanical aspects.In order to
Short circuit is prevented when appearance accident, high temperature fuse 121 interrupts the voltage in onboard power system.The high temperature fuse 121 is disconnected
It is replaced after opening by End-Customer.
In addition, the onboard power system includes multiple electric loading 123-1 and 123-2, for the electronics control of the internal combustion engine 117
The Gasoline Engine Electronic Control System of mechanism 125(Motronic(processed Bosch)), ignition switch 127 and safety box 129.It is all in institute
It states the load 123-1 and 123-2 outside starter 101 and is all connected to the vehicle by the fuse in safety box 129
On the anode of battery 109.Load 123-1, such as radio or the navigation system of some pairs of voltage-sensitives are additionally coupled to
On DC/DC converter 149, which is maintained at the voltage stabilization on 12V.

Have for the vehicle greater than 200,000 start-up course for for example running or sliding in operation in start-stop,
The relay 119 of the machinery may advanced wear so that required service life is not achieved in it.In addition it may generate
Other sources of trouble, for example, the relay 119 trembling, block or cling situation, these situations can damage the starting
Device 101, if not cutting off the starter.
In the starter 101 starting, the short time flows the high current for being greater than 500A, and the high current can make
Voltage in the onboard power system falls into the numerical value for dropping below 9V.In this case, interior illumination can dimmed or control
Instrument or actuator can be cut off.This feelings can occur for running vehicle particularly with running or sliding in start-stop
Condition, if starting the internal combustion engine 117 within driving cycle.
Passing through the ignition switch 127 or the electronic control mechanism 125(Motronic) start engine when, institute
It states relay 119 and connects the starter 101.This causes the closure of the engagement of the pinion gear and principal current switch.Institute

Operation there may be vibration, the vibration is passed on the starter 101.If power electric device is mounted on institute
It states on starter 101, then the power electric device is likewise subjected to these vibrations.This especially may be to institute when temperature is higher
The service life for stating the contact connectio of power electric device generates deleterious effect.In this case, by the onboard power system
Module 100 is mounted on this scheme on the Vehicular battery 109 and is advantageous, because reducing the oscillation load and can be with
Reach required service life.
In addition, reducing lead inductance in the case where transporting out of starter and being installed.When adjusting starter current,
About 150 are in and is converted ... the electric current in the range of 600A.Due to the lead inductance, in fact it could happen that high and conductor length
Proportional self-induction.The conversion of high inductance represents high load for switch.Therefore, route is shortened into minimum
Spend load of this way reduction when cutting off electric current.
Replace the relay 119 by including the electronics, thyristor 111 without abrasion, thus
Avoid the mechanical problem generated when using the relay 119.In addition it is possible to use novel meshing schemes, for
The engagement of the namely described pinion gear of the task-that the machinery is no longer undertaken by the relay 119 for the meshing schemes.
Starter current can be adjusted to previously given maximum value, be used for by means of the onboard power system module 100
The voltage disturbance is restricted to a kind of numerical value at the start, the continuation of interior actuator can operate for the numerical value,
This numerical value is, for example, the voltage of 11V.By the onboard power system module 100, can in the pinion gear engagement process or
Person adjusts the electric current of the starter 101 after its engagement, and the starter is cut off after having carried out starting process
Electric current.In addition, other function may be implemented by the corresponding control for the thyristor 111, such as
The stable starting accelerated or noise is few.Lesser support can be equally realized in across-the-line starting or by for described
The rotational speed regulation of starter 101 is engaged to the pinion gear in the internal combustion engine 117 of coasting.
Three kinds of functions can be unified in unique component by the onboard power system module 100.It in this case can be with
Cancel the mechanical relay 119 for the starter 101.By the use of the onboard power system module 100, can be improved
The service life of the starter 101.Structure space required for the starter 101 reduces, and the pass of the starter
In the angular installation position of engagement shaft be free.
Fig. 3 shows the schematic diagram of the onboard power system module 100.The onboard power system module 100 includes for should
Onboard power system module 100 is electrically connected to battery wire 103 on the Vehicular battery 109, for by the onboard power system module

Once the internal combustion engine 117 operates, then terminate the starting process.By the thyristor 111 come
The circuit of starter 107 is disconnected, the circuit of starter is then over the whole length without current potential.Therefore, occur accident or
Short circuit risk is not present when circuit of starter 107 described in person is damaged.
The battery wire 103 is connected (terminal 15) with the anode of the Vehicular battery 109 and has greatly transversal
Face is configured to solid busbar connector, because up to the electric current of 1000A will flow through.The starter wiring 105 passes through starting
Device route 107 and the starter 101(terminal 15) it is connected, and equally there is big cross section.The battery wire
103, the starter wiring 105 and 115 construction of the ground line are in the shell of the onboard power system module.
The thyristor 111 can be by multiple MOSFETs(Metal Oxide Semiconductor Field Effect Transistor)
Or other high-current switch are constituted.The MOSFETs forms resistance and limits electric current.The MOSFETs parallel arrangement
And in dynamic linear operation.The thyristor 111 possesses connection and cuts off and adjust described rise
