Technical Concepts Explained

PDK (Porsche Doppelkupplung): A dual-clutch transmission system that allows for gear pre-selection, enabling near-instantaneous gear changes without interrupting power delivery to the wheels.
TC275 Aurix: A high-performance multicore microcontroller from Infineon designed for automotive safety and engine/transmission management applications requiring high processing power.
TCU (Transmission Control Unit): The electronic brain of an automatic transmission that uses sensor data to calculate the optimal timing and pressure for gear shifts and clutch operations.
