Clutch control method for vehicle, involves engaging clutch in steps involving determining engine drive shaft and gearbox input shaft revolution rate difference gradient

摘要

The method involves engaging the clutch (14) by determining an engine (12) drive shaft (20) and gearbox (16) input shaft (22) revolution rate difference gradient, checking whether it exceeds a threshold, repeating the process if so, if not engaging the clutch further by a defined amount, checking if it is fully engaged, finishing if engaged and repeating the process if not fully engaged. Independent claims are also included for the following: an arrangement for controlling a clutch in a motor vehicle.
