Abstract

The invention discloses a steering auxiliary system and a steering auxiliary control method based on the transverse acceleration of an intelligent rail train. The steering auxiliary system comprises an automatic tracking switch, a vehicle body information acquisition device, a track identifying device, a steering auxiliary control device, an active steering device and a driving device; the automatic tracking switch is used for starting or shutting down automatic tracking; the vehicle body information acquisition device is used for collecting the motion parameter of the intelligent rail train and sending the motion parameter to the auxiliary control device; the track identifying device is used for collecting and treating the image information of a road surface preset reticule and sending the image information to the steering auxiliary control device; and the steering auxiliary control device is used for controlling the active steering device and the driving device to adjust the advancing of the intelligent rail train according to the received motion parameter and the image information of the road surface preset reticule. The steering auxiliary system and the steering auxiliary control method can avoid the problems that the intelligent rail train is sideslipped or drifted by a motor tractor when the intelligent rail train steers at a high speed or passes through a bend and a longmarshalling intelligent rail train is difficult in steering.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a steering assistance system and a control method based on the lateral acceleration of an intelligent rail train. Background technique [0002] Urban traffic is a symbol to measure the progress of urban civilization and the lifeblood of urban life. With the development of social economy and the improvement of people's living standards, the number of motor vehicles has increased sharply, which has deteriorated the urban traffic environment, reduced the traffic efficiency of the road network, and slowed down the main / auxiliary road traffic. This kind of long-term and large-scale congestion not only affects people's daily life and work, but also makes urban pollution more serious, which has become a "bottleneck" restricting urban economic and social development. Innovating the way of urban transportation and improving the efficiency of urban transportation has be...
