Abstract:
PCT No. PCT/GB94/02055 Sec. 371 Date Mar. 29, 1996 Sec. 102(e) Date Mar. 29, 1996 PCT Filed Sep. 22, 1994 PCT Pub. No. WO95/09996 PCT Pub. Date Apr. 13, 1995A method of controlling a vehicle driveline including an engine, a continuously variable ratio transmission (CVT) and a final drive in which over a working range of engine speed, the engine is constrained to work to a performance map correlating each value of engine speed to a particular value of engine torque wherein a demand by a driver for a increase in vehicle speed initiates a quick increase in engine speed to a predetermined engage speed without any substantial rise in the final drive speed and then increasing both engine speed and drive speed by a predetermined function until a selected engine speed limit is reached which is commensurate with the driver's demand, and finally maintaining the selected engine speed limit despite further changes in the final drive speed whereby the ratio range of the CVT is extended by providing two regimes of operation with a synchronous ratio between those regimes and the predetermined function is graphically represented as a straight line slope which corresponds to the slope the synchronous ratio. The invention also relates to a driveline controlled by the method.
