Abstract: A method comprises controlling at least one of a first distance between a first side of the vehicle and the first guidance track and a second distance between a second side of the vehicle and the second guidance track and receiving a direction instruction corresponding to one of the first side and the second side, the one side being a directional side. Having received directional instruction, a directional distance between the directional side of the vehicle and one of the first guidance track and the second guidance track provided at the directional side of the vehicle is controlled. With no contact between vehicle and a guiding track, for example comprising rails, the distance between the vehicle and the guiding tracks along the trajectory needs to be controlled, preferably at a safe distance. This concept provides such control.
