Gearbox assembly, for a motor vehicle, has a computer control to set the transmission train rotary speed to the target gear speed on changing gears before the new gear is engaged

摘要

The motor vehicle gearbox assembly (1), with at least two forward gears, has a transmission train (4) with a clutch (3) and gears (2) driven by the motor (5). A computer control (6) determines the rotation energy of the transmission on changing a gear for the moment of the motor on connection to the target gear, The control increases the rotation energy at the gear input side (16) to raise the motor moment and engage the target gear when the rotary speeds match.
