IMPROVEMENTS IN OR RELATING TO TRANSMISSION CONTROL ARRANGEMENTS OF MULTIPLE AXLE DRIVEN VEHICLES |
摘要 |
An arrangement for the control of the force-transmission of a four-wheel drive vehicle in which a main driving axle is driven directly by an internal combustion engine by way of a clutch transmission unit and an auxiliary driving axle is driven by the internal combustion engine by way of a continuously controllable longitudinal clutch. A desired traction force of all wheels is determined from a desired power output and from a velocity of the vehicle, from which a control magnitude for the control of the longitudinal clutch is obtained by a distribution factor dependent on operating or driving parameters. The longitudinal clutch can additionally be controlled either alone or advantageously also in combination with this control magnitude by a further control magnitude which is determined by a square of a rotational speed difference at the longitudinal clutch, having a weighting dependent on operating or driving parameters. The driving behavior achieved therewith enables a good steerability of the vehicle with maximum driving safety and traction. |
