用語(terms)

Term	Description
BSW	Basic Software
BswM	Basic Software Mode Manager
ComM	Communication Manager
DCM	Diagnostic Communication Manager
Det	Default Error Tracer
EcuM	ECU State Manager module
I-PDU	Information Protocol Data Unit
NM	Network Management
PDU	Protocol Data Unit
SW-C	Software Component
VMM	Vehicle Message Matrix
OA TC10	Open Alliance TC10 specification (see [33])
IRA	Internal Request Array. This is a bit vector which contains the aggregated internal PNC requests per channel. (see also chapter 8.6.2 “Nm_UpdateIRA”)
EIRA	External and Internal Request Array. This is a bit vector which contains the aggregated external and internal PNC requests
ERA	External Request Array. This is a bit vector which contains the aggregated external PNC requests. Each ComMChannel which has a ComMGatewayType set is has one corresponding ERA
ERAn	All External Request Arrays which are available in ComM, i.e. “n” ComMChannels were ComMGatewayType is set, result in “n” External Request Arrays in ComM
DCM_ActiveDiagnostic indication	The DCM module indicates an active diagnostic session. DCM need “full communication” = COMM_FULL_COMMUNICATION for diagnostic purpose
Active wake-up	Wake-up caused by the hosting ECU e.g. by a sensor.
Application signal scheduling	Sending of application signals according to the VMM. Scheduling of CAN application signals is performed by the Communication Module, scheduling of LIN application I-PDUs (a PDU containing signals) is performed by the LIN interface and scheduling of FlexRay application PDUs is performed by the FlexRay Interface module.
Bus sleep	No activity required on the communication bus (e.g. CAN bus sleep).
Bus communication messages	Bus communication messages are all messages that are sent on the communication bus. This can be either a diagnostic message or an application message.
COM Inhibition status	Defines whether full communication, silent communication or wakeup is allowed or not.
Communication Channel	The medium used to convey information from a sender (or transmitter) to a receiver.
Communication Mode	Mode determining which kind of communication are allowed: “full communication” = COMM_FULL_COMMUNICATION “no communication” = COMM_NO_COMMUNICATION “silent communication” = COMM_SILENT_COMMUNICATION Note: COMM_SILENT_COMMUNICATION can not be requested by a user. Internal mode for synchronizing network at shutdown
Diagnostic PDU scheduling	Sending of diagnostic PDUs. Scheduling of CAN diagnostic PDUs is performed by the diagnostic module, scheduling of LIN diagnostic PDUs is performed by the diagnostic module and the LIN interface and scheduling of FlexRay diagnostic PDUs is performed by the diagnostic module and the FlexRay Interface module.
ECU shut down	See ECU State Manager specification [6].
Fan-out	Same message/indication are sent to multiple destinations/receivers
Independent software component	A separately developed software component performing a coherent set of functions with a minimum amount of interfaces to other software applications on an ECU. This can be e.g. a basic software component or an application software component.
Passive wake-up	Wake-up by another ECU and propagated (e.g. by bus or wake-upline) to the ECU currently in focus.
System User	An administration functionality (a specific "user", which is generated within the internal context of the ComM) for making a default request and for overriding the user requests.
User	Concept for requestors of the ECU State Manager module and of the Communication Manager Module. A user may be the BswM, a runnable entity, a SW-C or a group of SW-Cs, which act as a single unit towards the ECU State Manager module and the Communication Manager Module.
User Request	A User can request different Communication Modes from ComM
Managed channel	A ComM channel that is referenced exclusively from one other channel by ECUC parameter ComMManageReference (see ECUC_ComM_00893).
Managing channel	A ComM channel that references 1..n other channels by ECUC parameter ComMManageReference (see ECUC_ComM_00893).
