In-vehicle networks are communication systems within a vehicle that allow different electronic components to exchange information. These networks connect various systems, such as the engine control unit, infotainment system, and safety features, enabling them to work together efficiently. Common protocols used in these networks include CAN (Controller Area Network) and LIN (Local Interconnect Network). These networks enhance vehicle performance, safety, and user experience by facilitating real-time data sharing. For example, when a driver activates the brakes, the in-vehicle network ensures that the anti-lock braking system and traction control systems respond promptly, improving overall vehicle stability and safety.
