Abstract: The increasing number of electrical components and sensors in modern vehicles makes network design more challenging. The development of automotive electronics through multiple communication protocols brings out the importance of a hybrid network that is both optimal and fault-tolerant. In order for a vehicle to communicate with electronic components like engine management systems, stability control units, braking systems, and door functions, a CAN (controller area network) is developed. In order to create a hierarchical vehicle network gateway for quality fortification and cost reduction of vehicles, the CAN and LIN (local interconnect network) are considered. This standardisation will reduce the variety of low-end multiplex solutions currently available for automotive electronics’ development costs, production rates, service fees, and logistics costs. The implementation of a gateway in these electronic devices is made possible with the proposed hybrid architecture. This system effectively shows the high-speed and low-speed applications relevant to crucial ECUs in the network by using two distinct CAN and LIN gateways to send sensor data between the ECUs (electronic control units).
