Abstract

An articulated vehicle with a controllable wheel route includes a first vehicle body, a first pair of wheels, which are individually suspended on both sides of the first vehicle body, and can travel on the ground, a second vehicle body hingedly connected to the first vehicle body, a second pair of wheels, which are individually suspended on both sides of the second vehicle body, and can travel on the ground, a regulator, which regulates a relative steering angle between the first vehicle body and the second vehicle body, a mode selector, which is configured to select a first mode and a second mode, and a controller, which receives the first mode signal or the second mode signal from the mode selector and controls the regulator according to the received signal. The route of a second pair of wheels is regulated to be identical to the route of a first pair of wheels in the first mode, and the route of a second pair of wheels is regulated to be different from the route of a first pair of wheels in the second mode.
