Networked intelligent vehicle formation and running control method on basis of spatial domains

Abstract

The invention relates to a networked intelligent vehicle formation and running control method on the basis of spatial domains. The networked intelligent vehicle formation and running control method includes that front vehicle information of controlled vehicles can be acquired by control systems of the controlled vehicles, the controlled vehicles can be communicated with front vehicles to acquire the front vehicle information, head time intervals and head distances of head locations of the controlled vehicles and the front vehicles when the front vehicles run through the current locations of the controlled vehicles can be computed by the control systems, the front vehicle information at the intervals of certain distances on roads can be computed by the control systems at the current head time intervals of the controlled vehicles and the front vehicles, controlled vehicle information and the computed front vehicle information can be combined with each other by the control systems, acceleration, brake and steering procedures of the controlled vehicles can be optimized, optimization results can be transmitted to power devices, brake devices and steering devices of the controlled vehicles, and vehicle running can be optimized by the aid of optimization principles. The networked intelligent vehicle formation and running control method has the advantages that networked intelligent vehicle longitudinal control and transverse control procedures can be simultaneously optimized, the optimization precision can be improved, repeated iteration can be omitted by optimization algorithms, and accordingly computation load can be relieved.

Description

technical field [0001] The present invention relates to the joint control of vehicle subsystems of different types or functions; the technical field of road vehicle driving control systems not associated with the control of a specific subsystem, in particular to a system based on real-time collection and transmission of vehicle information to the network The acceleration, braking, and steering processes of connected smart vehicles are optimized so that the vehicles can form a stable formation. A spatial domain-based control method for connected smart car formations. Background technique [0002] The connected smart car is equipped with advanced on-board sensors, controllers, actuators and other devices, and integrates modern communication and network technologies to realize intelligent information exchange and sharing between vehicles and people, vehicles, roads, and clouds. Functions such as decision-making and collaborative control can realize "safe, efficient, comfortable...

Problems solved by technology

[0011] The technical problem solved by the present invention is that in the prior art, the control method of the networked intelligent vehicle separates the longitudinal control and the lateral control, the road information is not included in the control model, the control accuracy of the vehicle cannot meet the actual traffic conditions, and the control based on the time domain The method cannot guarantee the driving safety of the vehicle, and the high-load calculation will cause great pressure on the vehicle computing system. The uncertain calculation time makes the calculation delay cannot be accurately estimated in advance, and it is impossible to achieve high-precision and fast vehicle control.
