Abstract: The invention proposes a drive system for a vehicle, in particular for a tracked vehicle, having a drive machine and at least one load, which is mechanically coupled to an output drive of the drive machine, at least one control means being associated with the at least one load and reducing a power consumption of the at least one load in a starting phase of the drive machine temporarily compared with a power consumption in an operating state of the load whilst maintaining the mechanical coupling. Such a drive system has an improved starting capability compared with known systems since the reduction in the power consumption of the load in the starting phase of the drive machine reduces the risk of the drive machine stalling. The drive system according to the invention is considered to be particularly advantageous in the case of hydraulic loads and generators.
