Complete vehicle computing platform system architecture design method and complete vehicle computing platform system architecture

Abstract

The invention discloses a whole vehicle computing platform system architecture design method, wherein a whole vehicle computing controller and one or more intra-domain controllers are included, and the whole vehicle computing controller is respectively connected with each intra-domain controller; the whole vehicle operation controller is configured for: (1) providing unified storage resources, computing resources, security computing resources and log records for the intra-domain controllers; (2) providing unified power management and supply for the intra-domain controllers, and loading and deleting functions of the intra-domain controllers; and (3) providing a point-to-point communication service for the intra-domain controllers. According to the invention, the utilization efficiency of whole vehicle resources is improved, the dynamic control of the intra-domain controllers is realized, and the communication efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of vehicle controller system architecture, and in particular relates to a system architecture design method of a vehicle computing platform and a vehicle computing platform system architecture. Background technique [0002] The current vehicle has gradually undergone the following changes: [0003] (1) From the perspective of demand and function, there are three changes, 1) from mechanical control, electric control to automatic control, and then to multi-scene-based control (based on voice / gesture / human / emotion); 2) from a single point in the car Function to multi-point linkage function; 3) Expand from in-vehicle function to in-vehicle combination function (network / data channel); then based on the current main CAN communication network, main fuse / relay power supply network, main single controller node , Increase the controller nodes according to the increase of functions (divergence but not convergence), no...

[0003] (1) From the perspective of demand and function, there are three changes, 1) from mechanical control, electric control to automatic control, and then to multi-scene-based control (based on voice / gesture / human / emotion); 2) from a single point in the car Function to multi-point linkage function; 3) Expand from in-vehicle function to in-vehicle combination function (network / data channel); then based on the current main CAN communication network, main fuse / relay power supply network, main single controller node , Increase the controller nodes according to the increase of functions (divergence but not convergence), no longer adapt to new requirements;

[0004] (2) There are three kinds of challenges from the logical and physical dimensions, 1) resource waste caused by multiple control nodes / computing power cannot be used uniformly; 2) upstream and downstream data pressure based on data channels; 3) lack of external interaction capabilities; then based on The logical and physical structure of the vehicle required in the past needs to be optimized or reconstructed to support new requirements and functions;
