A vehicle, a single-wheelset/double-wheelset trackless train and a tracking and steering control method therefor are provided in the invention. The method includes the following steps. During traveling of the vehicle, steering information of the vehicle is continually collected by the controller. Information about a guiding front wheel turning angle, a controlled rear wheel turning angle, a vehicle body position angle, an included angle between vehicle bodies, and a vehicle travel time and speed is collected; an interval for data collection is determined according to a distance between a guiding front wheel and a controlled rear wheel; and when the controlled rear wheel travels to a certain point near a front wheel travel track, the controlled rear wheel is controlled to travel in a travel direction same as that when the front wheel travels to the point. According to the rear wheel tracking and steering control method, the objective that a controlled rear wheel operates in a manner of highly approaching a guiding front wheel track can be achieved; and the higher a data collection frequency is, the higher a track fitting degree of the front wheel and the rear wheel is.

An articulated vehicle assembly comprising a master vehicle having a master steering system and an onboard sensor arrangement configured to monitor at least said master steering system; a slave vehicle having a slave steering system and an onboard actuator arrangement configured to manipulate at least said slave steering system; an articulation system for articulating in a queue the master and the slave vehicles along a common longitudinal axis; and a processing unit configured to receive input signals from the onboard sensor arrangement and produce corresponding output signals to the onboard actuator arrangement to manipulate said slave steering system so as to maintain the master vehicle and the slave vehicle aligned along the common longitudinal axis, at least when the master vehicle performs a turn on a horizontal plane.

A first process acquires movement data including a position of a lead machine. A second process controls one or more work machines so that the one or more work machines follows the lead machine based on the movement data.

A drive arrangement in a vehicle having front and rear ground engaging means and steering means, has a differential transmission, a differential lock, a planetary final drive on each side of the vehicle and a motor acting onto one member of the planetary final drives. The motor is controlled depending on the steering angle such, that it provides for a difference in the drive speed on the left and the right side.
