AI Technical Summary
Conventional in-vehicle communication systems face issues such as long transmission delay, high jitter, and low bandwidth utilization due to the exponential increase in data transmission requirements with advanced vehicle sensors and controllers, which are not adequately addressed by existing technologies like CAN, LIN, and FlexRay.
Implementing an in-vehicle communication system with automotive slice networks (ASN) that utilize gateways with ASN apparatuses to transmit data in ASN transport units (ATU) based on a slot rule, enabling direct transmission between gateways and service nodes without encapsulation, and using a consistent physical layer coding rule to improve speed and bandwidth efficiency.
This approach reduces transmission delay and jitter while enhancing bandwidth utilization by ensuring data is transmitted accurately and efficiently through a physical layer interface, adapting to varying data sizes and bus types.
