Learn AUTOSAR-SAFETY-MODULES with Real Code Examples

AUTOSAR Safety Modules enable automotive software to meet ISO 26262 functional safety requirements.

They include features such as error detection, safety monitoring, watchdog management, and redundancy handling.

Support both Classic AUTOSAR and Adaptive AUTOSAR platforms.

Facilitate integration with other AUTOSAR modules like RTE, BSW, and communication stacks.

Widely used in critical automotive systems like braking, steering, powertrain, and ADAS.

Functional safety compliance per ISO 26262

Runtime monitoring of software components

Fault injection and detection testing

Safety-related event logging

Safe communication protocols and memory handling

Safety Manager - oversees safety-related tasks

Watchdog - monitors task execution timing

Diagnostic Event - reports detected faults

Redundancy - parallel or duplicated tasks for consistency

Fail-Safe - pre-defined response to detected errors
