Abstract

A vehicle with a controllable wheel route includes a vehicle body, a first pair of wheels, which are individually suspended on both sides of the vehicle body to roll on the ground and can rotate around the vertical axis, a second pair of wheels, which are individually suspended on both sides of the vehicle body to roll on the ground, can rotate around the vertical axis, and are placed in the back of the first wheels, a regulator, which regulates each steering angle on the vertical axis of the first and second wheels, 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 second wheel route is regulated to be identical to the first wheel route in the first mode, and the second wheel route is regulated to be different from the first wheel route in the second mode.
