Control system and method for controlling the driving-away manoeuvre in a motor vehicle with a servo-controlled gearbox |
摘要 |
What is described is a control system for controlling the driving-away manoeuvre in a motor vehicle provided with a gearbox (G) comprising a primary input shaft which can be coupled to a drive shaft of a propulsion system of the vehicle (E) by means of a servo-assisted friction clutch. A control unit receives at its input signals indicating a command imparted by the driver of the motor vehicle by operating the accelerator pedal (P ACC ), and generates - on the basis of a mathematical reference model - reference torque request signals (C MRif ,C FRif ) indicating the reference torques requested from the drive shaft and from the friction clutch during the driving-away manoeuvre, and also generates - by comparison between signals (É MRif ,É PRif ) indicating the estimated angular velocities of the drive shaft and of the primary gear shaft, and detected signals (É M ,É P ) indicating the actual angular velocities of the drive shaft and of the primary gear shaft - corresponding corrective contributions (”C M ,”C F ), in such a way as to construct command signals for controlling torque actuator devices (ACT E ,ACT G ) of the propulsion system (E) and of the friction clutch, for controlling the driving-away manoeuvre in the motor vehicle. |
