Car body controller BCM as described in Figure 2 includes a microcontroller, and the input of microcontroller leads to successively
Power module TV1, mu balanced circuit, filter circuit is crossed to be connected with input power V1；Between power module and power output end
It is also associated with being grounded filter unit；Microcontroller is also associated with digital/analog signal input and output control unit.
Filter circuit as described in Figure 3 refers to that two filtered electricals over the ground are sequentially ingressed between mu balanced circuit and power module
Hold C1 and C2；The ground connection filter unit refers to same between power module and output earth terminal to be sequentially ingressed into two and filter over the ground
Ripple electric capacity C3 and C4.
Each vehicle factory would generally carry out being divided into different zones according to functional requirement to vehicle framework, and high end configuration would generally
There are multiple network segments, as shown in Figure 1.A parts are had in the middle of the different network segments to be responsible for the information of different segment（Letter
Number and message）Interaction is transmitted, the function of the router used in its effect and our families is very much like, and we claim this
Part is called gateway control unit.Because light-weighted design is increasingly taken seriously in recent years, in order to optimize complete vehicle weight, by this
Partial function is integrated into car body controller BCM, so can both realize the light-weighted purpose of vehicle, also reduces automobile research
Cost.
Car body controller BCM can realize that signal and the transmission of message are carried out between different segment to be handed in this patent
Mutually；Car body controller participates in network management, and the monitoring to vehicle signal is remained before vehicle sleep；Fault diagnosis can allow
Car body controller to its own diagnose while can also carry out network dependent diagnostic（Record fault message）；Switch collection can be with
Data signal or collection of simulant signal important on some vehicles are entered into car body controller and bus signals hair is converted into
It is sent on the corresponding network segment；Online writing with a brush dipped in Chinese ink makes car body controller online to be risen to vehicle parts by vehicle diagnosis interface
Level.So only car body controller may simultaneously connect vehicle upper band CAN, LIN buses and in vehicle parts
A little important data signals or remaining parts of analog signal input, therefore it is the optimal choosing of information of vehicles tape deck
Select.
In order to the record for realizing information of vehicles is acted on, car body controller not only carries out the transmission and interaction of signal and message,
The all information of vehicles that will should be processed simultaneously are stored in memory cell Flash, due to itself memory space inadequate, to ensure
Car body controller can completely records all data and ensures the length of data record, to the system architecture of car body controller slightly
Adjustment, increases an external memory storage, for the record storage of vehicle data.In the storing process of data, can be to storage
Unit carries out the storage of partition domain, while can also erasable and reprogram be carried out to it, the storage of the amount of storage according to signal and selection
The size of unit can draw the time of record vehicle data message.It is each that high end configuration system architecture as shown in Figure 2 is related to
All signals of controller persistently record a month space about 5G for needing（1G=1024M）.Each vehicle factory can voluntarily select
Select the size of memory cell, it is proposed that selection memory size can meet storage more than one month, after such vehicle breaks down
A period of time in we data convert can will be carried out by analysis software in the data copy in memory cell to computer,
Time according to user feedback can quickly find the vehicle data message at corresponding time point, so as to improve the effect of solve problem
Rate.
The thing of storage is solved, also another more crucial problem, is exactly powerup issue.When vehicle appearance is different
The special circumstances such as normal off electricity cause vehicle electric power system exception, then just seem extremely important in this crucial time data,
It is which control unit causes Full Vehicle System to be paralysed extremely.The current all controllers of vehicle cannot record vehicle at this hour
Data message, certain difficulty is brought to case study.In order to ensure the integrality of vehicle data information, it is set to work to most
Latter to engrave record vehicle data information, its power module must just be carried out particular design, make car body controller at remaining by us
Can be with registration of vehicle data message, as shown in Figure 3 in a period of time that control unit is all stopped.VI is input power supply；
TV1 is power module, and the power supply signal of input is mainly converted to the power supply signal for being available for parts inside to use of stabilization for it；
To prevent power input from producing peak voltage to cause to damage or disturb power module for some reason, spy is in power input
Terminate a voltage-regulator diode D1 formation mu balanced circuit over the ground and play a part of voltage-stablizer in whole circuit；Due to power supply
Signal typically all carries a certain degree of clutter, in order to ensure the stabilization of power supply signal, therefore the input in power supply and output
Terminate into filter capacitor C2, C3 and C4 over the ground, when capacitance is chosen, C2 and C4 can choose the same order of magnitude, or even the big I of capacitance
Generally all it is microfarad range with completely the same, between typically all 20uF ~ 50uF conventional at present, representative value is 22uF.Filtered electrical
Hold C3 when being to there is larger clutter in circuit, what C4 cannot be realized being completed filtering out and specially added, choosing appearance
It is usually that between 10 times ~ 20 times of C4, conventional value is 470uF during value；In order that car body controller BCM can work to last
A moment, the selection for accessing direct-to-ground capacitance C1, C1 capacitance in power input is just especially exquisite, because electric capacity is all as you know
There is energy storage, when vehicle power supply is normal, power input charges to storage capacitor C1, until electric capacity is fully charged simultaneously
Full power state is maintained, when power input sudden shuts off, the electric energy that C1 stores early stage is put by power module loop
Electricity calculate the capacitance of C1 until discharge off, the data time according to vehicle needs storage, and the selection of usual C1 capacitances is all
Can be that between 2300 times ~ 2400 times of C2, conventional value is 4700uF, if the capacitance obtain it is too small if cannot its storage electricity
Can ensure that car body controller can work at the last minute, it is impossible to ensure the integrality of record data, if the capacitance takes
Really the integrality that data message record can be ensured too much, but after remaining all control unit is all stopped, car
It is meaningless that the data record of body controller also becomes, and the volume of electric capacity can also increase a lot, it is often more important that cost meeting
Increase at double, loses more than gain.Therefore it between 2300 times ~ 2400 times of C2 is optimal that the selection of C1 capacitances is, you can ensured
The integrality of recording data information, again can be by cost control within the specific limits, in order to avoid cause unnecessary cost to waste.
Can be designed so that the function of car body controller is more powerful more than, between can not only realizing different segment
Signal and message interaction, the memory cell Flash for extending out allows it persistently to control unit of engine EMS, gearbox
Control unit TCU, airbag control module ABAG, electronic stabilizing control system ESC, combination instrument IPC, rotary angle transmitter system
The control such as system STE, keyless entry and activation system PEPS, air-conditioner controller CCU, electric booster steering device EPS and multimedia MHU
The data message of unit processed carries out effective monitoring and records, and the data recorded by car diagnostic interface OBD are derived simultaneously
Data convert is carried out using corresponding software, for the analysis and judgement of vehicle trouble provide science, the foundation of authority；Optimization
Power module design more can be the effective integrality for ensureing data message record, be that scientific and efficient problem analysis is provided with
The guarantee of power, for the optimization of product design in the future provides scientific basis.
