Abstract: A method is provided for the determination of a torque which is transmitted along a torque transmission path which extends at least along a shaft of a motor vehicle. A rotary position signal is produced by a first speed of rotation sensor at a first section of the transmission path and a rotary position signal is produced by a second speed of rotation sensor at a second section of the transmission path. At a point in time at which a known torque is transmitted along the transmission path, a first rotary position signal relationship is determined with reference to the instantaneously generated rotary position signals, the rotary position signal relationship serving as an offset value. At a later point in time, a second rotary position signal relationship is determined with reference to the instantaneously generated rotary position signals. The transmitted torque is calculated on the basis of the offset value and of the second determined rotary position signal relationship.

Abstract: A hydrostatic/mechanical multiple path power transmission comprises an adjustable hydrostat unit (4), a summing planetary gearbox (10) with two input shafts (6, 8) and at least two output shafts, and a step gearbox (11) connected to the output shafts. In order to adjust low speeds and standstill precisely and rapidly, the following method is specified: rotational speed signals are formed by sensors (50, 51) on the two input shafts (6, 8) of the summing planetary gearbox (10), and are compared with each other by counters (61, 62); the actual pulse count difference formed in this way is compared with a desired pulse count difference, and a controller [sic] and the output signal of a controller (66) that responds to the result of this comparison effects adjustment of the hydrostat (4).
