Patent ID: 8417398

Claim:
A vehicle, comprising: a first drive; and a second drive including a controller; wherein the first drive and the second drive are connected for data transmission; wherein at least one of (a) a rotation speed, (b) a torque, and (c) values of variables at least one of (i) dependent on and (ii) associated with at least one of (a) the rotational speed and (b) the torque of the first drive are transmittable to the controller of the second drive; wherein the controller is configured to determine a rotational speed specification for the second drive in accordance with the at least one of (a) a rotation speed, (b) a torque, and (c) values of variables at least one of (i) dependent on and (ii) associated with at least one of (a) the rotational speed and (b) the torque of the first drive and in accordance with at least one of (a) a torque and (b) corresponding values of corresponding variables of the second drive; wherein the drives are rigidly connected via a linkage; wherein each drive is adapted to drive at least one respective wheel, which is subject to slip, to produce forward motion by the wheels running on rails.
