Vehicle-end communication and vehicle-road coordination (V2X)

 

Vehicle-end communication and vehicle-road coordination (V2X) are two important concepts in intelligent transportation systems. Vehicle-end communication can realize information sharing between vehicles, such as road condition information, traffic congestion information, etc., to help drivers choose the best driving route.
Vehicle-end communication and vehicle-road coordination can help improve road safety, reduce traffic congestion, improve traffic efficiency, and create a more convenient, comfortable and safe travel environment for people.

Perception

 

The perception system is an important part of the intelligent driving of the car. It is responsible for detecting the environment of the car, providing accurate, timely and sufficient data basis for the decision-making level of the advanced assisted driving system, and then the executive layer makes an accurate decision on the safe driving of the car. judge. It mainly includes environmental perception, internal perception and driver perception.
The objects of the environment perception include the driving path of the vehicle, traffic participants around the vehicle (such as other vehicles, pedestrians), driving status (such as the driver's own state, the vehicle's own driving state and the driving state of other vehicles around the vehicle) and driving environment (such as road surface conditions, road traffic congestion and weather conditions, etc.).

Positioning

 

The use of satellite, RTK, vision, dead reckoning and other combination of positioning technology, to meet the needs of self-positioning in a variety of complex scenarios, while matching high-precision maps to timely and accurately "inform" location information, so as to achieve lane-level positioning.

planning and decision making

 

According to the environmental perception results and accurate location information, "intelligent" planning in the route. At the same time, according to the real-time traffic information, autonomous obstacle avoidance, lane change, following, overtaking and other related decisions.

Control

 

Considering the principle of body kinematics and environmental information, the horizontal and vertical control of the vehicle is carried out comfortably and friendly under the premise of ensuring safety.

Big computing platform

 

Intelligent driving computing platform is the core component of intelligent driving system, which provides powerful computing power for intelligent driving. Through high-performance chips and optimization algorithms, it provides powerful computing support for intelligent driving, enabling vehicles to perceive the surrounding environment in real time, make decision planning and control execution.
Intelligent driving computing platform is one of the key technologies to realize intelligent driving, and its performance and reliability directly affect the safety and reliability of intelligent driving system.
