Abstract

The invention discloses an automatic driving intelligent adaptive method and system based on driving environment perception. Continuous situation perception of different driving scenes, environments, road conditions and vehicle states can be achieved through the construction of a situation environment perception model based on multiple levels and multiple dimensions. On the basis, a micro-service driving rule base generates automatic driving decision logic, dynamic arrangement combination and operation switching are carried out on sensors, algorithm combinations and functional components of different levels in real time, the environment and the state of a vehicle can be sensed more accurately, automatic driving guidance is more effectively carried out, computing resources of the system are saved, and a cruising ability is increased so that comfortable and safe driving is achieved.

Description

technical field [0001] The invention relates to the technical field of smart cars, in particular to an intelligent self-adaptive method and system for automatic driving based on driving environment perception. Background technique [0002] With the development of technology, smart cars are becoming more and more intelligent. While smart cars bring convenience and driving experience to people, the problem of car safety is becoming more and more prominent. The corresponding algorithm calculation combination for the sensor configuration of the existing automatic driving system is a prefabricated custom design, adaptation and debugging for different types of vehicles. Its requirements for computing power and system computing resources are basically fixed and do not vary with the actual driving scene. However, for different driving scenarios, such as closed highways, parking lots, mountain roads or urban traffic environments, as well as for different driving environments and weat...
