Abstract:
1. Control method for of a vehicle with an automatic manual transmission, the method for controlling during a gear shifting or during a drive-away, the method for controlling an automatic manual transmission which comprises a gearbox which is provided with at least one primary shaft and at least one secondary shaft connected to driving wheels and at least one clutch, which is interposed between the primary shaft of the gearbox and a drive shaft of an engine the control, the method comprising: determining, during a design phase, a nominal transmissibility function (FT) of the clutch, which provides the torque delivered by the clutch according to the degree of opening of the clutch; determining, during a design phase, a model of the engine; determining a target torque (T making the clutch pursue the target torque (T determining a target engine torque (T making the engine pursue the target engine torque (T estimating, when the clutch is operated in opening or closure, a torque (T measuring, when the clutch is operated in opening or closure, a rotation speed (ω low-pass filtering the rotation speed (ω calculating, when the clutch is operated in opening or closure, a torque (T wherein T wherein T wherein J wherein dω updating, when the clutch is operated in opening or closure, the transmissibility function (FT) of the clutch by using the torque (T using for the next control of the clutch the transmissibility function (FT) which has been updated having as a true reference the model of the engine.
