A CONTROL SYSTEM FOR A VEHICLE DRIVETRAIN |
摘要 |
The invention concerns an arrangement for controlling a vehicle drivetrain having an engine provided with a speed governor and a continuously variable transmission ("CVT'') incorporating a variator which is constructed and arranged to regulate its reaction torque. The control system comprises a control part (504) movable by the driver to provide a driver input, an open loop subsystem (511) for operatively coupling the control part to the governor (520) to control no-load speed of the governor in dependence on the driver input, a closed loop subsystem comprising a comparator (502) which receives a first control signal derived from the driver input and corresponding to a target engine speed, and a second control signal corresponding to engine speed, and which adjusts variator reaction torque in dependence upon a comparison of the first and second control signals causing the transmission to load the engine suitably to achieve the target engine speed. |
