Abstract
Reliability and responsiveness in vehicles are becoming more important as semi-automation and automation are becoming more prevalent. A redundant Ethernet network system is provided within a vehicle and includes a first node connected to a first sensor and a second node connected to a second sensor. A first Ethernet cable is connected between the first node and the second node, a second Ethernet cable is connected between the first node and an electronic control unit (ECU), and a third Ethernet cable connected between the second node and the ECU. Data from the first sensor and the second sensor is transmitted across the Ethernet network to reach the ECU. Data from these sensors is also compared and processed locally at the first node and the second node to improve reliability and to reduce processing load on the ECU.
