Torque sensing differentials can do that (Torsen for example). The Viscous unit uses perforated discs, rotating in fluid. The discs are stacked such that they alternate for the 2 output shafts, so when one axle is going faster than the other it will generate a hydraulic force against the other to speed up the slower axle. Unfortunately as the fluid heats up it loses it viscosity which makes the whole system ineffective.
