Brake Sensor Task
Safety-critical path with the highest priority. It preempts lower tasks to ensure immediate reaction.
Priority 7Real-Time Vehicle Sensor Management System
Interrupt-driven RTOS simulation with deterministic task behavior, priority-based scheduling, and safe shared resource handling for vehicle sensor events.
This project demonstrates how Brake, Collision, and Speed interrupts are mapped to ISR handlers, queued by priority, and executed through RTOS-style task scheduling while preserving predictable timing.
Sensor Task Overview
Collision Sensor Task
High-priority response task for collision detection events and intermediate safety handling.
Priority 6Speed Sensor Task
Monitoring and telemetry task with medium priority for regular speed-event processing.
Priority 5Architecture And Real-Time Behavior
Core Components
- Interrupt controller with virtual INT mapping
- ISR handlers for each sensor type
- Priority queue based RTOS scheduler
- Mutex-protected shared resource access
- Structured event logger with microsecond timestamps
Real-Time Properties
- Higher-priority preemption over running lower-priority tasks
- Deterministic event order for repeated input sequences
- Bounded interrupt and task response windows
- Safe concurrency through lock-based resource access
- Continuous stats collection for runtime verification
