Automotive Electronics

ECUs, sensors, actuators and the networks that connect them. The electronic nervous system of a modern vehicle: electronic control units, sensors and actuators, and in-vehicle networks — CAN, LIN, FlexRay and Automotive Ethernet — with the timing, bandwidth and interface calculations engineers use daily.

• 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.
• Sensors — Vehicles use 100+ sensors. Learn position and speed sensors (Hall, VR, crank/cam, wheel speed), pressure (MAP, brake, tyre), temperature (NTC thermistors), flow (MAF), oxygen/λ sensors, inertial sensors, and ADAS sensors (radar, camera, lidar, ultrasonic) — with signal conditioning and diagnostics.
• Actuators — Actuators turn ECU commands into motion, heat or light. Learn solenoids and injectors, DC and BLDC motors (throttle, windows, pumps, fans), relays and smart high-side switches, H-bridges, PWM control, inductive kickback and flyback protection, and current diagnostics.
• CAN — Controller Area Network is the backbone of in-vehicle communication. Learn the differential bus and termination, frame format (identifier, DLC, data, CRC, ACK), arbitration by priority, bit timing, error handling and bus-off, bus-load calculation, DBC signal databases and CAN FD.
• LIN — Local Interconnect Network is a low-cost, single-wire bus for simple sensors and actuators. Learn master/slave (commander/responder) operation, the frame (break, sync, protected ID, data, checksum), schedule tables, timing, LDF files and diagnostics.
• FlexRay — FlexRay is a deterministic, fault-tolerant 10 Mbit/s bus for chassis and x-by-wire. Learn time-triggered communication, communication cycles with static (TDMA) and dynamic segments, dual channels for redundancy, clock synchronisation, slot calculation and why Ethernet is replacing it.
• 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.
