Accompanying drawing explanation
The content expressed every width accompanying drawing in description of the invention below is briefly described:
Fig. 1 is system architecture diagram;
Fig. 2 is fault detect flow chart;
Fig. 3 is collision detection flow chart;
Fig. 4 is that car load wakes up flow chart up.
Detailed description of the invention
Seeing Fig. 1 to understand, electric motor car and hybrid vehicle long distance control system include that diagnosing protocol processes mould Block, memory module, vehicle collision signal detection module, wireless module, vehicle wake up control module, vehicle up Locating module, Vehicular charging monitor, and vehicle arousal function module.
Diagnosing protocol processing module, mainly completes automatically reading and backstage of vehicle each primary control DTC The passive execution of diagnostic instruction.It obtains vehicle high-voltage battery and whole vehicle state by CAN application protocol, Including vehicle speed, motor speed, high voltage bus electric current and battery SOC etc., and the information timing that will gather Store in the SD card that terminal carries.Vehicle persistently detects the malfunction mark of vehicle primary control simultaneously Position, to judge vehicle current failure state, and supports holding such as various diagnosing protocol services such as DTC readings OK.
By primary control is detected, mainly complete 3 kinds of infomation detection: vehicle operation data, vehicle The detection of charge data and storage, and the detection of vehicle each controller failure flag bit.Vehicle operation data and Vehicular charging data can complete the collection of vehicle data by reading CAN information, for improving terminal Platform motility, terminal does not resolve CAN information, but takes the mode of transparent transmission to issue backstage and carry out Resolve.Designing according to system, each primary control of vehicle includes entire car controller, electric machine controller, and Battery controller adds the signal of a logical bit in CAN application layer protocol, characterizes this controller current Whether there occurs fault, terminal simply detects this 3 flag bits, and without allowing each controller increase Very many fault flags represent each concrete fault, and when controller failure increases, CAN communication should It is made without any change with agreement and terminal software.Terminal itself possesses SD card, can store vehicle fortune Row and charge data.
When information detecting module detects vehicle fault sign position, diagnosing protocol processing module i.e. passes through standard Diagnosing protocol, such as in KWP on CAN diagnosing protocol, $ 18 service order reads concrete DTC data, And Current vehicle fault code indications is sent to backstage, process.Refer to when backstage actively sends diagnosing protocol When making, terminal completes transmission and the reception of return information and the passback of diagnosing protocol instruction according to command request.
Wireless module is communicated with user mobile phone and backstage by GPRS or 3G, for vehicle data and The wireless remote of user instruction transmits, and monitoring backstage communicates wirelessly, and obtains backstage instruction and uploads reality Time information of vehicles, meet the requirement that the electric motor car of national regulation monitors in real time;This module need to support that GSM wakes up up And sleep mode, can shut down at vehicle, remotely be called out by phone or message function under terminal standby pattern Awake terminal system.
Backstage possesses the functions such as network insertion, terminal data processing, electronic chart and data record, rear stand Structure should meet international NGTP (Next Generation Telematics Protocol) system standard, can lead to The smart mobile phone crossing api interface and personal user carries out communication.
User mobile phone has individual smart mobile phone program, can pass through ICP/IP protocol and backstage api interface communication, Complete the monitoring of Vehicular charging process, and the merit of final remote opening air-conditioning can be reached by waking up car-mounted terminal up Energy.
Vehicle collision signal detection module mainly includes that digital signal input and clash logic process function, and it is adopted With the cycle timely checking circuit of 100ms.When vehicle airbag collides ejection, air bag can export One cycle is square wave or the pulse-width signal of 100ms, and terminal passes through logical process, it is judged that vehicle is sent out Raw collision rift, understands and is sent to monitor backstage by wireless module by this signal with limit priority.Monitor Member i.e. recognizes vehicle collision information after receiving this signal, can take relevant rescue measure.
This system is provided with vehicle and wakes up control module up, and when vehicle is in inoperative, non-charging, vehicle is respectively controlled Device processed includes that vehicle monitor terminal, all in power down or resting state, can be possessed by wireless modules such as GSM Arousal function, make vehicle monitor terminal power on, and by waking up control module up, wake up up entire car controller and Battery controller, and open air-conditioner controller further, before getting on the bus, open electronic vapour driver in advance Car air-conditioning, meets the requirement of ride comfort.
This system is provided with vehicle localization module, and it is positioned by Big Dipper positioning chip or GPS chip, and passes through This signal is delivered to backstage by wireless module, determines vehicle current longitude and latitude position.
System possesses Vehicular charging monitoring, according to personal user's needs, is monitored Vehicular charging process. Present battery SOC electricity, charging complete estimated time etc. can be checked.Also can be instructed down by diagnosing protocol Sending out, by the control interface with battery manager BMS, the charging setting vehicle allows the time period.
When vehicle is in properly functioning and charging, this terminal is powered by Vehicular accumulator cell, battery and car load shape State acquisition module and wireless driving module are in running order, for the long distance control system set up with main engine plants It is connected, meets the requirement that the period of expansion electric automobile of national regulation monitors in real time.Simultaneously by vehicle is transported Driving behavior is further analyzed by row with charging interval section, service data etc. are deployable.
When the vehicle is running, can by backstage automatically to vehicle-mounted VMS BMS MCU controller, by diagnosis Agreement reads once its software version, and is uploaded to backstage preservation, facilitates vehicle each controller software version Management.
See Fig. 2-4, based on said system, electric motor car and the control of hybrid vehicle long distance control system Method is as follows,
After system start-up;
System detects whether to there is following fault successively, including: under (1), non-charged state, VMS controller Whether there is fault, under (2), charged state, whether BMS controller exists fault, under (3), charged state, Whether MCU controller exists fault;
If fault-free, then timing cycle detection, if there is fault, then current failure information is sent to backstage;
System is closed.
In system operation, when vehicle collision signal detection module collects collision alarm, lead to the most at once Cross wireless module to send this information to backstage, and periodically to continuously send out vehicle location signal to backstage.
When system is closed, can call a taxi mounted terminal phone by automatic poking for mobile phone, to wake up terminal up, backstage connects Receiving unlatching air-conditioning instruction, and be transmitted to terminal, monitor terminal opens loop circuit, and annular CMS etc. controls Device powers on, final execution air-conditioning opening program.
Normal power supplies module, CAN drive module, digital circuit blocks, wireless tcp/IP network system to be general Lead to and public technology, be no longer discussed in detail.
Above in conjunction with accompanying drawing, the present invention is exemplarily described, it is clear that the present invention implements not by upper State the restriction of mode, if the various unsubstantialities that the method design that have employed the present invention is carried out with technical scheme Improvement, or the most improved design by the present invention and technical scheme directly apply to other occasion, all exists Within protection scope of the present invention.
