    摘要: A drive system (DS) for a land craft comprises a machine system (M1, M2) for driving the land craft, the machine system comprising at least a first and a second electric machine (M1, M2) acting on a common drive shaft (S) for driving the land craft, and a control device (PE, PE1, PE2) which is adapted to control the machine system for operating in at least two rotating speed operation ranges (OR1, OR2) with different rotating speeds of the drive shaft (S). The first electric machine (M1) is controlled to operate in both rotating speed operation ranges (OR1, OR2) to provide a first drive torque, and the second electric machine (M2) is controlled to operate in only one of the rotating speed operation ranges (OR1) to provide a second drive torque in addition to the first drive torque.
