Automotive Embedded Systems

ECUs, AUTOSAR, diagnostics and functional safety. Embedded engineering in vehicles: ECU design, AUTOSAR, on-board diagnostics and UDS, ISO 26262 functional safety, ASPICE processes, instrument clusters, gateways, automotive Ethernet and ADAS.

• ECU — Electronic Control Units run everything from engines to windows. Learn ECU hardware (microcontroller, power supply, input conditioning, drivers, communication), the harsh 12 V automotive environment (load dump, reverse polarity, EMC, temperature), watchdogs, and the shift to domain and zonal controllers.
• AUTOSAR — AUTOSAR standardises automotive ECU software. Learn Classic Platform layers (application SWCs, RTE, basic software, MCAL), ports and interfaces, runnables and events, configuration and code generation, the Adaptive Platform for high-performance computers, and CPU-load estimation.
• Diagnostics — On-board diagnostics detect and report faults. Learn OBD-II and EOBD, the malfunction indicator lamp, diagnostic trouble codes (DTC structure, status bits), freeze frames, readiness monitors, fault debouncing and healing, and the service workflow with scan tools.
• UDS — Unified Diagnostic Services (ISO 14229) is the standard language between testers and ECUs. Learn request/response structure, key services (0x10, 0x11, 0x14, 0x19, 0x22, 0x2E, 0x27, 0x28, 0x31, 0x34/36/37, 0x3E), negative response codes, sessions and security access, and ISO-TP transport over CAN.
• ISO 26262 — ISO 26262 is the functional-safety standard for road-vehicle E/E systems. Learn the safety lifecycle, hazard analysis and risk assessment (severity, exposure, controllability), ASIL determination, safety goals and requirements, hardware metrics (SPFM, LFM, PMHF), software methods and safety mechanisms, and SOTIF.
• ASPICE — Automotive SPICE assesses and improves software and system development processes. Learn the process reference model (SYS.1–5, SWE.1–6, SUP, MAN), capability levels 0–5, process attributes and N/P/L/F ratings, work products, bidirectional traceability, and how OEMs use assessments.
• Instrument Cluster — The instrument cluster shows speed, rpm, warnings and information. Learn analog vs digital clusters, signal sources over CAN, speedometer regulations (ECE R39), odometer and fuel-gauge filtering, telltales and warning priority (ISO 2575), graphics rendering and HMI design.
• Gateway — The central gateway connects the vehicle's networks. Learn routing between CAN, LIN, FlexRay and Ethernet domains, signal vs PDU routing, latency and bus-load effects, diagnostic routing (DoIP to CAN), firewalling and cybersecurity (SecOC, IDS), and evolution toward zonal architectures.
• Automotive Ethernet — Automotive Ethernet provides high-bandwidth, scalable networking for cameras, ADAS, infotainment and backbones. Learn single-pair PHYs (100BASE-T1, 1000BASE-T1, multi-gig), switches and VLANs, TSN for determinism, SOME/IP and DoIP protocols, bandwidth calculations and zonal architectures.
• ADAS — Advanced Driver Assistance Systems help drivers avoid crashes and reduce workload. Learn SAE automation levels, sensors and fusion, core functions (AEB, ACC, LKA, BSD, parking), time-to-collision and braking calculations, the perception–planning–control pipeline, validation and safety standards.
