Problems solved by technology

At present, if a single-core centralized solution is used, it often cannot meet the requirements of performance, function, safety, and vehicle regulations. For example, using an industrial computer platform will be easier to develop, but it cannot meet the requirements of mass production. Nvidia's ASIC has better performance in visual perception, but cannot support other sensors. Nvidia's PX2 platform has better performance, but in general power consumption and scalability

Abstract

The invention relates to a distributed multi-core heterogeneous system. The multi-core heterogeneous system is characterized in that it is composed of multiple platforms of different types, wherein the multiple platforms are connected through a communication network, and vehicle processing modules that implement different functions are respectively deployed on the multiple platforms, wherein , the system includes: a first platform consisting of one or more FPGAs; a second platform consisting of one or more GPUs; and a third platform consisting of one or more MCUs. According to the present invention, the superposition of multi-platform computing capabilities can be used to improve perception accuracy, optimize system computing resource utilization efficiency, and increase system stability. The distributed multi-core heterogeneous system of the present invention can meet the accuracy requirements of L4 level automatic driving perception fusion.

Description

technical field [0001] The invention relates to related vehicle automatic driving technologies, in particular to a distributed multi-core heterogeneous system for vehicle automatic driving. Background technique [0002] According to the definition of autonomous driving level by NHSTA (National Highway Safety Administration) and SAE International (Society of Automotive Engineers International) under the U.S. Department of Transportation, L4 refers to the ability to Achieving fully automatic driving, L5, means that the vehicle must be able to cope with all working conditions, including being able to achieve fully automatic driving under intense driving (that is, extreme conditions). [0003] L4-L5 autonomous driving puts forward higher requirements for the perception fusion planning system, especially for perception fusion, which requires the perception fusion system to have stronger processing capabilities, better safety performance, and support the access of more sensors. A...
