More Information
Summary:The invention concerns a method for automatically controlling a motor vehicle (10) for switching from a "normal" mode to a "freewheel" mode, the vehicle (10) comprising an engine (12) capable of providing engine torque to drive wheels (14) via an automatically controlled clutch device (18) that comprises a drive shaft (15) and a driven shaft (16). A transition step (E1) is interposed chronologically between the "normal" mode and the "freewheel mode" during which the engine (12) is automatically controlled in such a way that the driven shaft (16) and the drive shaft (15) turn at the same speed without transmitting torque to the drive wheels (14).
