Virtual rail train and rail generation method and auxiliary driving method and system thereof

Abstract

The invention discloses a virtual rail train and a rail generation method, an auxiliary driving method and a system thereof, which sense an external environment in real time, control the automatic steering and automatic acceleration and deceleration of the train, solve the problem of a driving blind area brought to a driver by an ultra-long flexible marshalling, improve the intelligence and safety level of the whole train and improve the comfort level of the whole train.

Description

technical field [0001] The invention relates to the field of rail transportation, in particular to a virtual rail train and its driving assistance method and system. Background technique [0002] The public traffic congestion in large and medium-sized cities has seriously affected the healthy development of cities in our country. Even in the second and third tier cities, the public traffic situation is not optimistic. Adhering to the priority development of public transportation, establishing a multi-level integrated public passenger transportation system with rapid rail transportation as the backbone, road public transportation as the main body, and taxis as the supplement has become the mainstream of urban public transportation development. The rail transit network based on subways and light rails has a long construction period and huge costs, and cannot cover all areas of large and medium-sized cities. Second- and third-tier cities cannot afford the construction costs. T...

AI Technical Summary

Problems solved by technology

Due to the particularity of the super virtual rail train vehicle, the driver at the side of the tail cannot judge obstacles or dangers only by visual observation, and it is difficult for the driver to control the steering and acceleration and deceleration of the vehicle to meet the control requirements of the vehicle. Therefore, An assisted driving system that senses the external environment in real time and controls the vehicle's automatic steering and automatic acceleration and deceleration is needed

[0004] The methods of the prior art only control a single vehicle (i.e. a single vehicle), or only control the longitudinal traction and braking of the train, which cannot solve the problem of driving blind spots brought by super-long flexible marshalling to drivers. It also cannot solve the problem of vehicle lateral control (lateral control is the steering control of each axle tire of the vehicle) brought by the super virtual rail train.
