IMPROVED GEAR RATIO CHANGE METHOD FOR HEAT ENGINE POWERED VEHICLE PROVIDED WITH A TURBOCHARGER

摘要

The invention relates to an improved gear ratio change method implemented with a vehicle comprising a heat engine (4) capable of being supercharged by a turbocharger (9) and a clutch (7) installed between the heat engine (4) and a gearbox (6) connected with one of the drive axles (8) of the vehicle. In accordance with the invention, the set torque (Ccons) when the clutch (7) is in a slipping phase is a torque greater than the maximum dynamic torque (Cdyn) of the engine (4).
