Description

A kind of multi-module system

Technical field

The present invention relates to technical field of automobile control, be specifically related to a kind of multi-module system.

Background technology

Along with the deep application of CAN system, increasing vehicle begins to use car body control module (Body Control Module, BCM) replace the traditional control method of the electrical appliance kit+relay of non-CAN vehicle.Automatically controlled due to automobile Parts get more and more (car door, car light, windscreen wiper, defrosting, exsiccator, air-conditioning panel, retarder etc.), and distribution also ratio is relatively decentralized, and one Individual module is difficult to meet the demand for control of car load, generally requires installation two or three modules simultaneously and could meet car load Demand for control, this has occurred as soon as multi-module system.

Present multi-module system, each module is an independent control unit, has been responsible for specific function.As Front module controls windscreen wiper, Qianmen, headlight, frost removal etc.；Rear module controls brake lamp, back-up lamp, back door etc..Due to function not With, pin definitions and routine processes logic are the most different, cannot be general between different modules.And between each module, lack letter Breath is shared, and wants to increase a function or revise and controls logic and be required for changing module and could realize, is not easy to function Upgrading.Owing to bus market Customization demand is more, cause the product category of module day by day to increase, add the life of company Produce management cost and after service cost, be unfavorable for the generalization of product.

Utility model content

This utility model provides a kind of multi-module system, solves increase function or amendment controls logic and needs to change The problem of module.

A kind of multi-module system, it is characterised in that this system includes that ICU combination instrument, described ICU combination instrument connect respectively Meeting 1 ~ 4 general module IOU, CAN connects ICU combination instrument respectively and each general module IOU, described ICU combine instrument Table is connected one to one by corresponding activation wire respectively with the pin of each general module IOU；

It is mutual that described ICU combination instrument carries out information by CAN and each general module, for being responsible for control logic Process, configuration general module, activate general module, output open or close the instruction of general module, processing system power on and under Electric current journey, display system duty；

Described general module IOU is for being responsible for collection car load signal, performing control instruction, and can diagnose output pin Short circuit, open circuit and overload fault, the vehicle body signal condition collected, output pin state are issued ICU group by CAN Close instrument；

Described activation wire is used for connecting ICU combination instrument and general module IOU, is used for transmitting information, leads to simultaneously as CAN The address wire of news, determines general module source address in CAN communication by the on-position of activation wire.

Further, described activation wire is rigid line.

What this utility model produced has the beneficial effect that:

This utility model utilizes 4 general module IOU, and general module is general material, and self is as broad as long, therefore improves The modularity of product, generalization degree, save cost.When customer demand increases, changes or control logic change, only Need the main controlled node ICU that upgrades, it is not necessary to change module.Activation wire, the most again can be as logical as the transmission line of information By the address wire of module I OU, simplify wire harness and connect.And specify the activation signal output pin of ICU combination instrument and general The activation signal input pin of module I OU must be one to one, prevents wire harness wrong, it is ensured that the reliability of system.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

Further details of explanation this utility model is carried out below in conjunction with the accompanying drawings with specific embodiment, but of the present utility model Protection domain is not limited to this.

The present invention provides a kind of multi-module system, and this multi-module system is by an ICU combination instrument and 1 ~ 4 general module IOU forms.ICU combination instrument connects 1 ~ 4 general module respectively, and CAN connects ICU combination instrument respectively and each is general Module, described ICU combination instrument is connected one to one by corresponding activation wire respectively with the pin of each general module；

ICU combination instrument is the main control module of system, carries out information by CAN and each general module mutual, negative Duty controls logical process, configuration general module, activation general module, sends instruction, the place opening or closing general module and exporting Reason system electrification and lower electric current journey, display system duty.IOU is responsible for gathering car load signal, performing control instruction, and can With the diagnosis short circuit of output pin, open circuit and overload fault, by CAN the vehicle body signal condition collected, outlet tube Feet state issues ICU combination instrument by CAN.Activation wire is used for connecting ICU combination instrument and general module IOU, is used for Transmission information, the activation wire of general module is also the address wire of CAN communication simultaneously.

As it is shown in figure 1, ICU combination instrument 5 include 4 activation signal output pin WKOUT1, WKOUT2, WKOUT3, WKOUT4,4 general module IOU are respectively IOU11, IOU22, IOU33, IOU44, and each general module IOU includes 4 respectively Activation signal input pin WKIN1, WKIN2, WKIN3, WKIN4, but each general module IOU only one of which activation signal is defeated Enter pin activation signal output pin corresponding with ICU combination instrument 5 to be connected by activation wire 7.General module IOU passes through Judgement is which activation signal input pin is effective, it is possible to know self address in systems, say, that activation wire 7 Wire harness can be simplified connect as the address wire of general module IOU the most again.And specify the activation signal of ICU combination instrument 5 The activation signal input pin of output pin and general module IOU must be one to one, prevents wire harness wrong, it is ensured that system Reliability.The activation signal that the WKOUT1 of ICU combination instrument 5 connects first general module IOU11 by activation wire 7 inputs The activation signal that the WKOUT2 of pin WKIN1, ICU combination instrument 5 connects second general module IOU22 by activation wire 7 is defeated Enter the activation signal that pin WKIN2, the WKOUT3 of ICU combination instrument 5 connect the 3rd general module IOU33 by activation wire 7 The activation that the WKOUT4 of input pin WKIN3, ICU combination instrument 5 connects the 4th general module IOU44 by activation wire 7 is believed Number input pin WKIN4.CAN 6 connects ICU combination instrument 5, general module IOU11, general module IOU22, general respectively Module I OU33 and general module IOU44.In system power-on phase, ICU combination instrument 5 first starts, then according to WKOUT1, The order of WKOUT2, WKOUT3, WKOUT4 activates corresponding general module IOU, in combination with Universal Die one by one by activation wire 7 CAN message ID that block IOU sends judges, if message ID and activation wire are inconsistent, then explanation system wiring is wrong, system Can point out and activate unsuccessfully, thus ensure the reliability of system.

Being noted that above-described embodiment is illustrative not limiting to technical solutions of the utility model, affiliated technology is led The equivalent of territory those of ordinary skill or other amendment made according to prior art, as long as not exceeding this utility model skill The thinking of art scheme and scope, within should be included in the interest field required by this utility model.
