Power control system with stall prevention clutch modulation function

A control system for a work vehicle includes a power source including an engine and at least one electric motor configured to generate power; a transmission including a plurality of clutches coupled together and configured for selective engagement to transfer the power from the engine and the at least one electric motor along a power flow path to drive an output shaft of a powertrain according to a plurality of transmission modes; and a controller coupled to the power source and the transmission. The controller has a processor and memory architecture configured to: monitor an electric motor speed of the at least one electric motor; and generate and execute, when the electric motor speed is less than a first predetermined stall speed threshold, a clutch modulation command for the transmission such that at least one clutch of the plurality of clutches along the power flow path is partially engaged.

Clutch control apparatus for vehicle

A clutch control apparatus includes: a judder extractor for extracting a judder component based on a speed of a transmission input shaft; an anti-judder signal generator for generating a basic control signal, which is a reverse phase signal to the judder component, based on the judder component extracted by the judder extractor; a signal separator for separating an amplitude and a phase of the basic control signal received from the anti-judder signal generator; and a signal post-processing device for respectively adjusting the amplitude and the phase output from the signal separator and then combining the same together to output anti-judder torque.
