用語(terms)

Term Description
Callback Refer to the Glossary [5]
Callout ’Callouts’ are function stubs that the system designer can replace with code, usually at configuration time, to add functionality to the ECU Manager module. Callouts are separated into two classes. One class provides mandatory ECU Manager module functionality and serves as a hardware abstraction layer. The other class provides optional functionality.
Integration Code Refer to the Glossary [5]
Mode A Mode is a certain set of states of the various state machines (not only of the ECU Manager) that are running in the vehicle and are relevant to a particular entity, an application or the whole vehicle
Passive Wakeup A wakeup caused from an attached bus rather than an internal event like a timer or sensor activity.
Phase A logical or temporal assembly of ECU Manager’s actions and events, e.g. STARTUP, UP, SHUTDOWN, SLEEP, ... Phases can consist of Sub-Phases which are often called Sequences if they above all exist to group sequences of executed actions into logical units. Phases in this context are not the phases of the AUTOSAR Methodology.
Shutdown Target The ECU must be shut down before it is put to sleep, before it is powered off or before it is reset. SLEEP, OFF, and RESET are therefore valid shutdown targets. By selecting a shutdown target, an application can communicate its wishes for the ECU behavior after the next shutdown to the ECU Manager module.
State States are internal to their respective BSW component and thus not visible to the application. So they are only used by the BSW’s internal state machine. The States inside the ECU Manager build the phases and therefore handle the modes.
Wakeup Event A physical event which causes a wakeup. A CAN message or a toggling IO line can be wakeup events. Similarly, the internal SW representation, e.g. an interrupt, may also be called a wakeup event.
Wakeup Reason The wakeup reason is the wakeup event that is the actual cause of the last wakeup.
Wakeup Source The peripheral or ECU component which deals with wakeup events is called a wakeup source.
