Abstract
A method controls state changes of a drivetrain of a vehicle connecting at least one heat engine and/or one electric motor to the wheels of the vehicle via a transmission, providing the transfer of torque from the heat engine and/or from the electric motor to the wheels in one or more gear ratios. The authorization to switch from a current state to a target state depends on reducing an acceleration of the vehicle in an intermediate state causing a lower acceleration of the vehicle during the transition between the current state and the target state.
