ABSTRACT:
An apparatus for controlling a hybrid drive system for a motor vehicle, an industrial truck in particular, with an internal combustion engine BKM, an accumulator for electric energy, an apparatus for acquiring the charge condition SOC of the accumulator, at least one electric engine E1/E2, which is connectable to the electric accumulator, and at least one gearbox arrangement, via which the internal combustion engine BKM, the electric engine E1/E2and at least one wheel of the vehicle can be coupled to each other, with the following features: a desired value transmitter for the travelling speed v, an actual value transmitter for the travelling speed v, a first controlling device for the travelling speed v, and a speed controller for the desired wheel torque; a torque calculation stage, which establishes the desired torque values for the internal combustion engine BKM as well as the desired values for the electric engine E1/E2from the desired driving torque M-soll or a signal corresponding to the same, a second controlling device, which drives the internal combustion engine BKM such that the deviations become sufficiently small, and a third controlling device, which drives the electric engine E/1/E2such that the deviations become sufficiently small.
