Flexible vehicle-mounted network system for intelligent driving and vehicle

Abstract

The embodiment of the invention discloses a flexible vehicle-mounted network system for intelligent driving and a vehicle. The system comprises a central computing and management platform, peripheralequipment and a plurality of deterministic low-delay switches, the plurality of deterministic low-delay switches are arranged on the vehicle body according to positions; the plurality of deterministiclow-delay switches form a ring network to be connected with the central computing and management platform; the peripheral equipment is divided into regions for networking according to the physical position and is connected with the deterministic low-delay switch nearby; the central computing and management platform is provided with a virtualized electronic control unit. And the whole vehicle-mounted network system adopts full Ethernet wiring. The vehicle comprises the system. According to the embodiment of the invention, the communication capability of the whole vehicle can be ensured under the conditions that the number of electronic equipment of the whole vehicle is increased, the communication traffic is increased and the network topology is complex and changeable, and the expandability and flexibility of the vehicle-mounted network can be improved.

Description

technical field [0001] The present application relates to the technical field of vehicle-mounted network systems, in particular to a flexible vehicle-mounted network system and vehicles for intelligent driving. Background technique [0002] In recent years, the increase in vehicle electronic devices and the improvement of intelligence have made vehicles more and more complex electronic equipment systems from the original mechanical products; their increasing complexity is reflected in their electrical and electronic components, such as sensors, execution devices, electronic control units (ECUs), and on-vehicle networks. [0003] The existing in-vehicle network is a heterogeneous in-vehicle network in which various buses such as CAN, FlexRay, and MOST coexist and are connected through a gateway. The domain controller is divided into domains according to functional domains, such as power domain, chassis domain, body electronics domain, intelligent driving domain, etc. As the...
