用語(terms)

Term	Description
AddressAndLengthFormat Identifier	Defines the number of bytes used for the memoryAddress and memorySize parameter in the request messages.
Application Layer	The Application Layer is placed above the RTE. Within the Application Layer the AUTOSAR Software-Components are placed.
Atomic Sender/Receiver interface	An atomic sender-receiver interface can be used to group DID data elements into one record data element prototype. All data elements can be read or write having a single read or write operation.
Channel	A link at which a data transfer can take place. If there is more than one Channel, there is normally some kind of ID assigned to the Channel.
Concurrent TesterPresent	A UDS service TesterPresent with set suppressPosRspMsgIndicationBit (3E 80) which is received with functional addressing. It is also known as keep-alive logic..
Diagnostic Channel	A link at which a data transfer between a diagnostic tool and an ECU can take place. Example: An ECU is connected via CAN and the diagnostic channel has an assigned CAN-ID. Diagnostic channels connected to other bus-systems such as MOST, FlexRay, LIN, etc. are also possible.
External Diagnostic Tool	A device which is NOT permanently connected to the vehicle communication network. This External Diagnostic Tool can be connected to the vehicle for various purposes, as e.g. for: • development • manufacturing • service (in a garage) Example External Diagnostic Tools are: • a diagnostic tester • an OBD scan tool The External Diagnostic Tool is to be connected by a mechanic to gather information from ”inside” the car.
Freeze Frame	A set of the vehicle/system operation conditions at a specific time.
Functional Addressing	The diagnostic communication model where a group or all nodes of a specific communication network receive a message from one sending node (1-n communication). This model is also referred to as ’broadcast’ or ’multicast’. OBD communication will always be done in the Functional Addressing mode.
Internal Diagnostic Tool	A device/ECU which is connected to the vehicle communication network. The Internal Diagnostic Tool can be used for: • advanced event tracking • advanced analysis • for service The behavior of the Internal Diagnostic Tool can be the same as of an External Diagnostic Tool. The notion of ”Internal Diagnostic Tool” does not imply that it is included in each ECU as an AUTOSAR Software-Component.
Physical Addressing	The diagnostic communication model where a node of a specific communication network receives a message from one sending node (1-1 communication). This model is also referred to as ’unicast’.
UDS Service	this refers to a UDS Service as defined in ISO14229-1 [1].
OBD Scan tool	See definition External Diagnostic Tool.
OBD Service	This refers to an OBD Service as defined in ISO15031-5 [2].
OBD UDS DTC separation	The feature will report a different 3 byte DTC number for SAE J1979-2 based UDS communication than for none J1979-2 UDS communication.
periodic transmission rate	Time interval value that defines the time between two calls of a periodic data identifier transmission. The value is configuration specific and there are separate values for fast, medium and slow periodic data transmission. The configured value is always an integer multiple of the Dcm main task time.
API	Application Programming Interface
CAN	Controller Area Network
CEMR	ControlEnableMaskRecord
Dcm	Diagnostic Communication Manager
Dem	Diagnostic Event Manager
Det	Default Error Tracer
DID	Data Identifier
DSD	Diagnostic Service Dispatcher (submodule of the Dcm module)
DSL	Diagnostic Session Layer (submodule of the Dcm module)
DSP	Diagnostic Service Processing (submodule of the Dcm module)
DTC	Diagnostic Trouble Codes
ID	Identifier
LIN	Local Interconnect Network
MCU	Micro-Controller Unit
MOST	Media Orientated System Transport
NRC	Negative Response Code
OBD	On-Board Diagnosis
OSI	Open Systems Interconnection
PDID	Periodic Data Identifier, periodically send by the Dcm after a request of ReadDataByPeriodicIndentifer
PDU	Protocol Data Unit
PID	Parameter Identifier
RCRRP	Response correctly received - response pending
RID	Routine Identifier
ROE	ResponseOnEvent
RTE	Runtime Environment
SAP	Service Access Point
SDU	Service Data Unit
SID	Service Identifier
SW-C	Software-Component
TP	Transport Protocol
UDS	Unified Diagnostic Services
Xxx_	Placeholder for an API provider
SPRMIB	suppressPosRspMsgIndicationBit
