Het is onderverdeeld in de hardware-stuurprogramma's fr (Communication Controller) en frtrcv (Transceiver), de centrale abstractielaag frif, de toestandsmanager frsm en het ISO-10681-2-transportprotocol frtp [SWS_FrIf_05001] [SWS_FrTp_01028].

Het datapoor wordt bestuurd via FrIf_Transmit, waarbij FrTp segmentatie- en reassemblagediensten biedt voor diagnoseberichten en grotere nuttige data [SWS_FrIf_05033] [SWS_FrTp_01009]. Tijdens runtime vindt de synchronisatie plaats via het cyclische TDMA-raster; FrTp_MainFunction moet normatief ten minste eenmaal per FlexRay-cyclus worden aangeroepen [SWS_FrTp_01152] SWS FlexRayISOTransportLayer p. 88. Interpretatie: dit dient vermoedelijk om de tijdige afhandeling van de ISO-10681-2-flowcontrol- en bevestigingstimers te waarborgen. Vraag (open)
Toestandsovergangen, wakeup-sequenties (single- en dual-channel) en de cluster-startup worden georkestreerd door FrSM, die de POC-toestanden van de controller via FrIf en Fr aanstuurt en de status doorgeeft aan ComM en BswM [SWS_FrSM_00013] [SWS_Fr_00010] SWS FlexRayStateManager p. 50.

Runtime- en hardwarefouten worden geïsoleerd via DET (bijv. ongeldige indices via FRIF_E_INV_CTRL_IDX) en DEM (bijv. FR_E_CTRL_TESTRESULT, FRSM_E_CLUSTER_STARTUP) [SWS_FrIf_05158] [SWS_Fr_00181]. Actieve sterkoppelaartakken kunnen bij storingen selectief worden gedeactiveerd via FrTrcv_DisableTransceiverBranch [SWS_FrTrcv_00442] SWS FlexRayTransceiverDriver p. 50.
Systeemarchitectuur & rol van het modulecluster
Het modulecluster FlexRay Communication biedt in het AUTOSAR Classic Platform (release R20-11) deterministische, realtime-capabele en fouttolerante communicatie via het FlexRay-bussysteem SWS FlexRayInterface p. 170. Het implementeert de op TDMA gebaseerde overdrachtsmethode (Time Division Multiple Access) en de transportlaag conform ISO 10681-2. Het cluster omvat vijf kernmodules: het FlexRay-stuurprogramma (fr), het FlexRay-transceiver-stuurprogramma (frtrcv), de FlexRay-interface (frif), de FlexRay State Manager (frsm) en de FlexRay ISO Transport Layer (frtp) [SWS_FrIf_05001].
De modules zijn verdeeld over de lagen van de AUTOSAR-basissoftware: het FlexRay-stuurprogramma fr behoort tot de Microcontroller Abstraction Layer (MCAL) en stuurt de Communication Controller (CC) en diens Protocol Operation Control (POC) rechtstreeks aan [SWS_Fr_00510]. Het transceiver-stuurprogramma frtrcv abstraheert de fysieke bustransceivers en ondersteunt naast standaardkanalen ook actieve sterkoppelaars (Active Stars) [SWS_FrTrcv_00487]. De FlexRay-interface frif ontkoppelt als centrale abstractie-instantie de bovenste lagen van de hardware door stuurprogrammatoegangen in te kapselen en controlleroverstijgende clusteroperaties beschikbaar te stellen SWS FlexRayDriver p. 36.
Op systeemniveau fungeert de FlexRay State Manager frsm als schakel tussen de systeemservices (Communication Manager ComM, Basic Software Mode Manager BswM) en de interface frif om de communicatiestatus van volledige FlexRay-clusters te besturen en terug te koppelen [SWS_FrSM_00199]. De FlexRay ISO Transport Layer frtp bevindt zich in de Communication Services en biedt segmentatie-, reassemblage- en flowcontrolediensten voor grotere hoeveelheden gegevens (bijv. voor diagnose via DCM of complexe applicatie-SDU's) boven de PDU-router (PduR) [SWS_FrTp_01028] SWS FlexRayStateManager p. 35.

Samenspel & interactiepaden tussen de modules
De reguliere verzenddatastroom begint bij de bovenste lagen (bijv. COM of FrTp), die PDU's via FrIf_Transmit overdragen [SWS_FrIf_05033]. FrIf controleert de onlinestatus van het cluster en stuurt het verzoek door naar de FlexRay-driver. Bij transport-PDU's vraagt FrTp via de flag TX_SDU_AVAILABLE en de interface PduR_FrTpCopyTxData gegevens op en bestuurt de toewijzing van vrije Tx-PDU-bronnen [SWS_FrTp_00416] [SWS_FrTp_01038]. Interpretatie: Bij de wisselwerking tussen FrTp en FrIf zal vermoedelijk de configuratie van PDU-pools en bufferinterfacemodi (Immediate vs. Decoupled Buffer Access) primair bepalen of payloadgegevens direct in de aanroepcontext dan wel tijdontkoppeld via Trigger-Transmit worden aangeboden SWS FlexRayInterface p. 68. Vraag Q-f84c2cfb8cc303a6 (open)
Aan de ontvangstzijde worden FlexRay-frames na ontvangst door de controller en driver overgedragen aan de FlexRay-interface, die geconfigureerde ontvangstindicaties (zoals FrTp_RxIndication) aanroept [SWS_FrTp_00152]. Voor gesegmenteerde datastromen buffert FrTp ontvangen N-PDU's, verwerkt protocolbesturingsinformatie (PCI) en vraagt via PduR_FrTpStartOfReception en PduR_FrTpCopyRxData bufferbereiken van de bovenliggende laag aan [SWS_FrTp_01074] SWS FlexRayISOTransportLayer p. 92.
Het transportprotocol conform ISO 10681-2 maakt onderscheid tussen ongesegmenteerde overdrachten via StartFrame (STFU zonder bevestiging, STFA met bevestiging) en gesegmenteerde processen [SWS_FrTp_01007] [SWS_FrTp_01008]. Bij gesegmenteerde transfers verzendt de ontvanger na het StartFrame flowcontrolframes (Flow Control, FC.CTS of FC.WAIT), waarna de zender Consecutive Frames (CF, CFEOB) en tot slot een Last Frame (LF) verstuurt [SWS_FrTp_01009]. Tijdens runtime kan de flowcontrol dynamisch via Bandwidth-Control-parameters (BC) via FrTp_ChangeParameter worden aangepast [SWS_FrTp_00242] AUTOSAR SWS FlexRay ISO TP p. 27.

Synchronisatie, re-entrantie en taakcontexten
De uitvoering in het FlexRay-cluster is nauw gekoppeld aan de statische communicatietijdbasis. Cyclische hoofdfuncties besturen periodieke taken: FrTrcv_MainFunction tast transceivertoestanden en wakeup-events af [SWS_FrTrcv_00330], terwijl FrTp_MainFunction ten minste eenmaal per FlexRay-communicatiecyclus moet worden uitgevoerd [SWS_FrTp_01152] [SWS_FrTp_00162]. Interpretatie: De uitvoering van FrTp_MainFunction ten minste eenmaal per FlexRay-communicatiecyclus borgt vermoedelijk een tijdige voortgang van de protocoltimers (zoals Timeout_BS en Timeout_CR) synchroon met het statische TDMA-raster SWS FlexRayISOTransportLayer p. 88. Vraag Q-c7a18cbb3c37b980 (open)
Voor temporele synchronisatie en programmabesturing in het TDMA-raster stelt het cluster absolute timers beschikbaar. Via FrIf_SetAbsoluteTimer, FrIf_EnableAbsoluteTimerIRQ en FrIf_AckAbsoluteTimerIRQ worden timer-interrupts in de CC geconfigureerd en bevestigd [SWS_Fr_00034] [SWS_FrIf_05021]. Verder stelt FrIf synchrone services beschikbaar voor het opvragen van de globale tijd (FrIf_GetGlobalTime), de cycluslengte (FrIf_GetCycleLength) en de macroticks (FrIf_GetMacrotickDuration, FrIf_GetMacroticksPerCycle) [SWS_FrIf_05015] [SWS_FrIf_05018] SWS FlexRayInterface p. 56.
Met betrekking tot re-entrantie en contexten geldt: driver-API's van de module fr zijn over het algemeen niet-re-entrant voor dezelfde controller-instantie (Non Reentrant for the same device) [SWS_Fr_00034]. De interfaces van de frif zijn re-entrant ontworpen voor verschillende cluster- resp. controller-indices. Bepaalde opvraagfuncties zoals FrIf_GetGlobalTime mogen expliciet binnen exclusieve gebieden worden aangeroepen [SWS_FrIf_05015] SWS FlexRayInterface p. 64.
Typische levenscycli en bedrijfsmodi
De initialisatie van het cluster verloopt hiërarchisch: de BSW-initialisatiesequentie start met FrSM_Init, waardoor alle clustertoestandsmachines overgaan naar de basistoestand FRSM_READY [SWS_FrSM_00013] [SWS_FrSM_00126]. Vervolgens worden de controllers via FrIf_ControllerInit geïnitialiseerd [SWS_FrIf_05004], en de module FrTp wisselt via FrTp_Init van de toestand FRTP_OFF naar FRTP_ON [SWS_FrTp_01032] SWS FlexRayStateManager p. 35.
De Communication Controller doorloopt daarbij de POC-toestandsmachine (Protocol Operation Control) conform de FlexRay-specificatie: vanuit toestand POC:ready leidt het commando RUN via Fr_StartCommunication de overgang naar POC:startup in [SWS_Fr_00010]. Als de ECU als coldstart-node is geconfigureerd, wordt via Fr_AllowColdstart het CHI-commando ALLOW_COLDSTART verzonden [SWS_Fr_00114]. Na succesvolle integratie en synchronisatie bereikt de controller POC:normal active of POC:normal passive [SWS_Fr_00507] [SWS_Fr_00509] SWS FlexRayDriver p. 42.
Voor de communicatiestart vereist een slapende bus een wakeup-procedure: FrSM coördineert single-channel- of dual-channel-wakeups. Het wakeup-kanaal wordt via FrIf_SetWakeupChannel geparametriseerd, de transceivers worden naar FRTRCV_TRCVMODE_NORMAL geschakeld en het wakeup-patroon (WUP) wordt via FrIf_SendWUP resp. Fr_SendWUP op de bus verzonden [SWS_Fr_00009] [SWS_FrIf_05011] [SWS_FrIf_05034]. De wakeup-oorzaak kan via FrTrcv_GetTransceiverWUReason worden geëvalueerd [SWS_FrTrcv_00325] SWS FlexRayStateManager p. 50.
Bij het afsluiten wisselt FrSM op verzoek van de ComM van COMM_FULL_COM naar COMM_NO_COM. De communicatie wordt via FrIf_HaltCommunication gestopt, FrIf schakelt via FrIf_SetState(FRIF_GOTO_OFFLINE) over naar de offlinemodus en de transceivers worden in STANDBY geplaatst [SWS_FrIf_05006]. Voor diagnose- of validatiedoeleinden kunnen clusters via FrSM_SetEcuPassive in een zuivere ontvangstmodus (ECU Passive) worden geplaatst [SWS_FrSM_00174]. Een volledige stop van FrTp vindt plaats via FrTp_Shutdown [SWS_FrTp_00148] SWS FlexRayStateManager p. 58.

Foutafhandeling, DET-tracing en degradatie
Bedieningsfouten en ongeldige API-parameters worden via de Development Error Tracer (DET) geregistreerd. Als er ongeldige controller- of kanaalindices worden doorgegeven of API's vóór module-initialisatie worden aangeroepen, melden FrIf, FrTp, FrTrcv en FrSM gestandaardiseerde fouten zoals FRIF_E_INV_CTRL_IDX, FRTP_E_INVALID_PDU_SDU_ID, FRTRCV_E_UNINIT of FRSM_E_INV_HANDLE aan de DET [SWS_FrIf_05158] [SWS_FrTp_01143] [SWS_FrTrcv_00462] [SWS_FrSM_00168] SWS FlexRayISOTransportLayer p. 77.
Ernstige runtime- en hardwarefouten worden gemeld aan de Diagnostic Event Manager (DEM). Hardwaretests van de controller signaleren fouten via het event FR_E_CTRL_TESTRESULT met status DEM_EVENT_STATUS_FAILED [SWS_Fr_00181] [SWS_Fr_00297]. Als de cluster-startup binnen de FrSM mislukt, wordt het diagnose-event FRSM_E_CLUSTER_STARTUP gemeld SWS FlexRayStateManager p. 50.
Voor degradatie en fouttolerantie biedt het cluster gerichte isolatiemechanismen: bij transceivers met actieve sterkoppelaars (Active Star) kunnen foutieve leidingtakken via FrTrcv_DisableTransceiverBranch resp. FrIf_DisableTransceiverBranch worden gedeactiveerd om storingen in het totale cluster te voorkomen [SWS_FrTrcv_00442] [SWS_FrIf_05028]. Lopend verzendverkeer kan selectief via FrTp_CancelTransmit en FrIf_CancelTransmit worden afgebroken, en individuele hardwarebuffers kunnen via FrIf_DisableLPdu worden vergrendeld [SWS_FrTp_00150] [SWS_FrIf_05710] SWS FlexRayTransceiverDriver p. 50.
