Summary:

Hydrostatic torque modulation is a new, at moment theoretical approach, to developing advanced AWD4WD transmissions. The basic component is a rotational hydrostatic modulator. It is derived from a low-speed high-torque hydrostatic machine. As such, it can be integrated into a standard mechanical AWD4WD transmission as a replacement for the clutch, where torque is controlled through energy dissipation. Controlled by a simple solenoid valve, it provides torque vectoring with a reaction time shorter than 0.5 s, and it provides additional safety features that result in a more robust AWD4WD transmission. As it can modulate torque with energy flow control/transfer, it offers much more than existing systems based on controlled clutches. Specifically, hydrostatic torque modulation, when it is integrated into the AWD4WD transmission, brings CVT or ICTAlthough you offer a list of abbreviations at the end of the manuscript, please check with your target journal regarding whether they should also be defined in the main text upon first mention.--> performance. As torque modulation is performed through the control of the energy flow, it provides torque control from 0 km/h without using a clutch. This option is relevant in extreme situations where standard solutions cause heat buildup that slows the advancement in order to protect the clutch from burning out. With the introduction of a hydrostatic torque modulator, for each wheel, allows for maneuvering similar to tracked vehicles id est the option of 180° spot turns. In addition, the technology can be integrated into mild hybrid vehicles with 48 V starter-generators. Such vehicles are thus transformed it into AWD4WD vehicles with ZEV Please note that this abbreviation is not in the list of abbreviations at the end of the document.-->options in traffic jams at speed limits of 40 km/h, and optional torque vectoring at speed limits well above 100 km/h. In addition, advanced suspensions can be developed
