EMC Challenges in Connected Cars
New vehicles contain a dazzling array of electronics. Trends such as the ‘connected car’, driver assistance systems and the move towards semi or fully autonomous vehicles are creating a huge demand on the electronics industry. However, with so many electronics systems within close proximity to each other, the potential for EMI problems is dramatically increased. Many of these autonomous systems make decisions that can have life-changing consequences. For example, interference to ultrasonic Advanced Driver Assistance Sensors (ADAS) from cellular radio signals needs to be eliminated at all costs. The challenges of EMI are compounded in electrically powered vehicles with high current systems in the drive train potentially creating significant transients throughout the vehicle.
