The path tracking control of intelligent networked vehicles can be divided into () and ().

The path tracking control of intelligent networked vehicles can be divided into preview following model and intelligent control model.

First, the control system of smart car

The control system of smart car is mainly divided into three parts: path planning, path tracking and automatic parking.

Second, the specific content of path planning

Path planning is to determine the position of obstacles and target points by providing useful information for autonomous driving through sensors, and to plan the optimal path from the starting point to the target point. ?

Path planning mainly studies the obstacle avoidance of vehicles, path tracking mainly studies the effectiveness of vehicles following the expected path, and automatic parking mainly analyzes that vehicles stop at designated spatial positions in a limited geometric space. Among them, path tracking is the core part. According to the different research methods, it is mainly divided into preview following model and intelligent control model.

The path planning module needs to provide a path that can guide the vehicle to the destination (or destination) according to the local environment perception, available global lane-level paths and relevant traffic rules. Path planning is the upper module, which solves the problem of how intelligent networked vehicles achieve their goals. It relies on high-precision maps customized for intelligent networked cars.

The definition of intelligent networked car:

I. Definition

Intelligent networked automobile is a new type of automobile system with cross-technology and cross-industry, and its understanding is different from different angles and backgrounds. Different countries have different definitions and names for the intelligent networked car, but the ultimate goal is the same, that is, a driverless car that can drive safely on the road.

Second, narrow sense.

Intelligent networked car is a new generation car equipped with advanced on-board sensors, controllers, actuators and other equipment, which integrates modern communication and network technology to realize V2X intelligent information exchange and enjoyment. It has complex functions such as environmental awareness, intelligent decision-making, collaborative control and execution, and can realize safe, comfortable, energy-saving and efficient driving, and finally can replace people to operate.

Third, in a broad sense.

Intelligent networked vehicle is a new generation of multi-vehicle system, which takes vehicles as the main body and nodes and integrates modern communication and network technology to realize information sharing and collaborative control between vehicles and external nodes, so as to realize safe, orderly, efficient and energy-saving driving of vehicles.
