Coordonne la communication FlexRay déterministe, les modes de bus et le transport de données segmenté sur des cycles TDMA.
Le cluster de modules FlexRay Communication met en œuvre l'échange déterministe de données selon le procédé TDMA ainsi que les transferts de diagnostic segmentés conformément à ISO 10681-2 dans AUTOSAR Classic R20-11 [SWS_FrIf_05001] SWS FlexRayInterface p. 170. Il coordonne, par l'intermédiaire des modules Fr, FrTrcv, FrIf, FrSM et FrTp, la gestion des modes à l'échelle du cluster, les motifs de réveil du bus et la synchronisation matérielle. Une contrainte temporelle stricte impose l'appel de la fonction principale de transport au moins une fois par cycle de communication FlexRay [SWS_FrTp_01152].
Dans AUTOSAR Classic R20-11, le cluster de modules FlexRay Communication garantit la communication déterministe basée sur TDMA via le système de bus FlexRay SWS FlexRayInterface p. 170. Il s'articule autour des pilotes matériels fr (Communication Controller) et frtrcv (émetteur-récepteur), de la couche d'abstraction centrale frif, du gestionnaire d'états frsm ainsi que du protocole de transport ISO 10681-2 frtp [SWS_FrIf_05001] [SWS_FrTp_01028].

Le chemin de données est commandé via FrIf_Transmit, FrTp fournissant des services de segmentation et de réassemblage pour les messages de diagnostic et les données utiles plus volumineuses [SWS_FrIf_05033] [SWS_FrTp_01009]. À l'exécution, la synchronisation s'effectue via la trame cyclique TDMA ; FrTp_MainFunction doit, de façon normative, être appelé au moins une fois par cycle FlexRay [SWS_FrTp_01152] SWS FlexRayISOTransportLayer p. 88.

FR_E_CTRL_TESTRESULT, FRSM_E_CLUSTER_STARTUP) [SWS_FrIf_05158] [SWS_Fr_00181]. En cas de perturbations, les branches d'étoile active peuvent être désactivées sélectivement via FrTrcv_DisableTransceiverBranch [SWS_FrTrcv_00442] SWS FlexRayTransceiverDriver p. 50.
Architecture système & rôle du cluster de modules
Le cluster de modules FlexRay Communication fournit dans l'AUTOSAR Classic Platform (Release R20-11) la communication déterministe, temps réel et tolérante aux pannes via le système de bus FlexRay SWS FlexRayInterface p. 170. Il implémente la méthode de transmission basée sur TDMA (Time Division Multiple Access) ainsi que la couche de transport selon ISO 10681-2. Le cluster comprend cinq modules cœurs : le pilote FlexRay (fr), le pilote de transceiver FlexRay (frtrcv), l'interface FlexRay (frif), le FlexRay State Manager (frsm) et le FlexRay ISO Transport Layer (frtp) [SWS_FrIf_05001].
Les modules se répartissent sur les couches du Basic Software AUTOSAR : le pilote FlexRay fr appartient à la Microcontroller Abstraction Layer (MCAL) et pilote directement le contrôleur de communication (CC) ainsi que son Protocol Operation Control (POC) [SWS_Fr_00510]. Le pilote de transceiver frtrcv fait l'abstraction des transceivers de bus physiques et prend en charge, outre les canaux standards, des étoiles actives (Active Stars) [SWS_FrTrcv_00487]. En tant qu'instance d'abstraction centrale, l'interface FlexRay frif découple les couches supérieures du matériel en encapsulant les accès aux pilotes et en fournissant des opérations de cluster multi-contrôleurs SWS FlexRayDriver p. 36.
Au niveau système, le FlexRay State Manager frsm agit comme lien entre les services système (Communication Manager ComM, Basic Software Mode Manager BswM) et l'interface frif afin de commander et notifier l'état de communication de clusters FlexRay entiers [SWS_FrSM_00199]. Le FlexRay ISO Transport Layer frtp est situé dans les Communication Services et offre des services de segmentation, de réassemblage et de contrôle de flux pour de plus grands volumes de données (par ex. pour le diagnostic via DCM ou des SDU d'application complexes) au-dessus du routeur de PDU (PduR) [SWS_FrTp_01028] SWS FlexRayStateManager p. 35.
Diagramme d'architecture : structure statique en couches et relations d'interaction des cinq modules dans le cluster FlexRay AUTOSAR. Sources : [SWS_FrIf_05001], [SWS_FrSM_00199], [SWS_FrTp_01028].
Interaction & voies d'interaction entre les modules
Le flux de données d'émission régulier commence au niveau des couches supérieures (par ex. COM ou FrTp), qui transmettent les PDU au moyen de FrIf_Transmit [SWS_FrIf_05033]. FrIf vérifie l'état en ligne du cluster et transmet la requête au pilote FlexRay. Pour les PDU de transport, FrTp demande des données via le drapeau TX_SDU_AVAILABLE et l'interface PduR_FrTpCopyTxData et contrôle l'attribution des ressources Tx-PDU libres [SWS_FrTp_00416] [SWS_FrTp_01038]. Interprétation : lors de l'interaction entre FrTp et FrIf, la configuration des pools de PDU et des modes d'accès aux tampons (Immediate vs. Decoupled Buffer Access) devrait principalement déterminer si les données utiles sont mises à disposition directement dans le contexte d'appel ou de manière temporellement découplée via Trigger-Transmit SWS FlexRayInterface p. 68. Question Q-f84c2cfb8cc303a6 (ouverte)
Côté réception, après réception par le contrôleur et le pilote, les trames FlexRay sont transmises à l'interface FlexRay, qui appelle les indications de réception configurées (comme FrTp_RxIndication) [SWS_FrTp_00152]. Pour les flux de données segmentés, FrTp met en mémoire tampon les N-PDU reçues, traite les informations de contrôle de protocole (PCI) et demande des zones de tampon de la couche supérieure via PduR_FrTpStartOfReception ainsi que PduR_FrTpCopyRxData [SWS_FrTp_01074] SWS FlexRayISOTransportLayer p. 92.
Le protocole de transport selon ISO 10681-2 distingue les transmissions non segmentées au moyen de StartFrame (STFU sans confirmation, STFA avec confirmation) des séquences segmentées [SWS_FrTp_01007] [SWS_FrTp_01008]. Lors de transferts segmentés, le récepteur envoie après le StartFrame des trames de contrôle de flux (Flow Control, FC.CTS ou FC.WAIT), après quoi l'émetteur transmet des Consecutive Frames (CF, CFEOB) et finalement un Last Frame (LF) [SWS_FrTp_01009]. À l'exécution, le contrôle de flux peut être adapté dynamiquement via des paramètres Bandwidth-Control (BC) au moyen de FrTp_ChangeParameter [SWS_FrTp_00242] AUTOSAR SWS FlexRay ISO TP p. 27.

Synchronisation, réentrance et contextes de tâches
L'exécution dans le cluster FlexRay est étroitement couplée à la base de temps de communication statique. Des fonctions principales cycliques gèrent les tâches périodiques : FrTrcv_MainFunction échantillonne les états des transceivers et les événements de réveil [SWS_FrTrcv_00330], tandis que FrTp_MainFunction doit être exécutée au moins une fois par cycle de communication FlexRay [SWS_FrTp_01152] [SWS_FrTp_00162]. Interprétation : l'exécution de FrTp_MainFunction au moins une fois par cycle de communication FlexRay devrait garantir une mise à jour en temps voulu des temporisateurs de protocole (tels que Timeout_BS et Timeout_CR) de manière synchrone avec la grille TDMA statique SWS FlexRayISOTransportLayer p. 88. Question Q-c7a18cbb3c37b980 (ouverte)
Pour la synchronisation temporelle et le contrôle du déroulement dans la grille TDMA, le cluster met à disposition des temporisateurs absolus. Les interruptions de temporisateur sont configurées et acquittées dans le CC via FrIf_SetAbsoluteTimer, FrIf_EnableAbsoluteTimerIRQ et FrIf_AckAbsoluteTimerIRQ [SWS_Fr_00034] [SWS_FrIf_05021]. De plus, FrIf fournit des services synchrones pour interroger l'heure globale (FrIf_GetGlobalTime), la longueur de cycle (FrIf_GetCycleLength) et les macroticks (FrIf_GetMacrotickDuration, FrIf_GetMacroticksPerCycle) [SWS_FrIf_05015] [SWS_FrIf_05018] SWS FlexRayInterface p. 56.
Concernant la réentrance et les contextes : les API de pilote du module fr sont en règle générale non réentrantes pour la même instance de contrôleur (Non Reentrant for the same device) [SWS_Fr_00034]. Les interfaces de frif sont conçues pour être réentrantes pour différents indices de cluster ou de contrôleur. Certaines fonctions d'interrogation comme FrIf_GetGlobalTime peuvent être explicitement appelées au sein de zones exclusives [SWS_FrIf_05015] SWS FlexRayInterface p. 64.
Cycles de vie et modes de fonctionnement typiques
L'initialisation du cluster s'effectue de manière hiérarchique : la séquence d'initialisation du BSW commence par FrSM_Init, ce qui fait passer toutes les machines d'état du cluster à l'état de base FRSM_READY [SWS_FrSM_00013] [SWS_FrSM_00126]. Ensuite, les contrôleurs sont initialisés via FrIf_ControllerInit [SWS_FrIf_05004], et le module FrTp passe de l'état FRTP_OFF à FRTP_ON par FrTp_Init [SWS_FrTp_01032] SWS FlexRayStateManager p. 35.
Le contrôleur de communication parcourt alors la machine d'état POC (Protocol Operation Control) conformément à la spécification FlexRay : à partir de l'état POC:ready, la commande RUN via Fr_StartCommunication amorce la transition vers POC:startup [SWS_Fr_00010]. Si le calculateur est configuré en tant que nœud de démarrage à froid (Coldstart), la commande CHI ALLOW_COLDSTART est émise via Fr_AllowColdstart [SWS_Fr_00114]. Après une intégration et une synchronisation réussies, le contrôleur atteint POC:normal active ou POC:normal passive [SWS_Fr_00507] [SWS_Fr_00509] SWS FlexRayDriver p. 42.
Avant le début de la communication, un bus en sommeil nécessite une séquence de réveil : FrSM coordonne les réveils monocanal ou bicanal. Le canal de réveil est paramétré via FrIf_SetWakeupChannel, les transceivers sont basculés en FRTRCV_TRCVMODE_NORMAL et le motif de réveil (WUP) est envoyé sur le bus via FrIf_SendWUP ou Fr_SendWUP [SWS_Fr_00009] [SWS_FrIf_05011] [SWS_FrIf_05034]. La cause du réveil peut être évaluée via FrTrcv_GetTransceiverWUReason [SWS_FrTrcv_00325] SWS FlexRayStateManager p. 50.
Lors de l'arrêt, FrSM passe de COMM_FULL_COM à COMM_NO_COM à la demande de ComM. La communication est arrêtée via FrIf_HaltCommunication, FrIf passe en mode hors ligne au moyen de FrIf_SetState(FRIF_GOTO_OFFLINE) et les transceivers sont placés en STANDBY [SWS_FrIf_05006]. Pour les cas de diagnostic ou de sécurisation, les clusters peuvent être mis dans un mode de réception pure (ECU Passive) via FrSM_SetEcuPassive [SWS_FrSM_00174]. Un arrêt complet de FrTp a lieu via FrTp_Shutdown [SWS_FrTp_00148] SWS FlexRayStateManager p. 58.

Gestion des erreurs, traçage DET et dégradation
Les mauvaises manipulations et les paramètres d'API non valides sont consignés via le Development Error Tracer (DET). Si des indices de contrôleur ou de canal non valides sont transmis ou si des API sont appelées avant l'initialisation du module, FrIf, FrTp, FrTrcv et FrSM signalent des erreurs standardisées telles que FRIF_E_INV_CTRL_IDX, FRTP_E_INVALID_PDU_SDU_ID, FRTRCV_E_UNINIT ou FRSM_E_INV_HANDLE au DET [SWS_FrIf_05158] [SWS_FrTp_01143] [SWS_FrTrcv_00462] [SWS_FrSM_00168] SWS FlexRayISOTransportLayer p. 77.
Les erreurs d'exécution et matérielles graves sont signalées au Diagnostic Event Manager (DEM). Les tests matériels du contrôleur signalent les erreurs via l'événement FR_E_CTRL_TESTRESULT avec l'état DEM_EVENT_STATUS_FAILED [SWS_Fr_00181] [SWS_Fr_00297]. Si le démarrage de cluster échoue au sein de FrSM, l'événement de diagnostic FRSM_E_CLUSTER_STARTUP est signalé SWS FlexRayStateManager p. 50.
Pour la dégradation et la tolérance aux pannes, le cluster offre des mécanismes d'isolation ciblés : pour les transceivers avec étoiles actives (Active Star), les branches de ligne défectueuses peuvent être désactivées via FrTrcv_DisableTransceiverBranch ou FrIf_DisableTransceiverBranch afin d'éviter des perturbations de l'ensemble du cluster [SWS_FrTrcv_00442] [SWS_FrIf_05028]. Les transmissions en cours peuvent être interrompues sélectivement via FrTp_CancelTransmit et FrIf_CancelTransmit, et des tampons matériels individuels peuvent être verrouillés via FrIf_DisableLPdu [SWS_FrTp_00150] [SWS_FrIf_05710] SWS FlexRayTransceiverDriver p. 50.
