  Introduction to Zonal Autonomous Control Zonal Autonomous Control (ZAC) is an emerging automotive architecture that organizes a vehicle’s electronic systems into different physical zones. Each zone manages specific functions, sensors, actuators, and electronic components located within a particular area of the vehicle. This approach helps simplify vehicle electronics, reduce wiring complexity, improve communication between systems, and support the development of software-defined vehicles. Traditional vehicles often rely on numerous electronic control units (ECUs), with individual controllers managing functions such as braking, lighting, powertrain operations, and climate control. As vehicles become more connected, electrified, and automated, this distributed architecture can increase system complexity, wiring requirements, and manufacturing costs. Zonal Autonomous Control addresses these challenges by consolidating control functions into zonal controllers that communicate with c...
