METHOD FOR STAGE-SWITCHING THE AUTOMATIC OR SYNCHRONIZED TRANSMISSIONS AT MOTOR VEHICLES

摘要

The functions M(y) and M(n) between the torque M of the engine, the position y of the accelerator pedal and the speed of rotation n are stored in an electronic control unit (13), in which the moment values pertaining to the measured acceleration signal and to the measured speed of rotation signal are picked out and a load signal s is generated. The signal s is compared with a constant shifting-up load value Sf and with a constant shifting-down load value Sv, and a command for shifting of gears (2) and friction clutch (3) is given to the servo unit (14). <IMAGE>
