    Abstract: Control method to carry out a gear shift in a manual automatic transmission provided with a gearbox having at least one clutch and in a road vehicle having an internal combustion engine and at least one reversible electric machine. The control method involves the steps of: receiving a gear shift command; opening and closing the clutch to allow the drive gear to be changed from the current gear to the following gear; determining a torque objective to be generated by the electric machine; controlling the electric machine to pursue the torque objective; and adding, only and exclusively during the gear shift, to the torque objective an additional torque profile which is impulsive and temporary and temporarily modifies the development of the torque objective.

    Abstract: Method to control an electric road vehicle having the steps of: detecting a position of an accelerator pedal; detecting an activation of an upshift control and of a downshift control; establishing a plurality of virtual gears, each capable of being selected by acting upon the upshift control and upon the downshift control; determining the selected virtual gear depending on the actions exerted upon the upshift control and upon the downshift control; determining a torque objective to be applied to the drive wheels depending on the position of the accelerator pedal and depending on the selected virtual gear; and adding, at each change of the selected virtual gear, to the torque objective an additional torque profile which is impulsive and temporary and temporarily changes the development of the torque objective.

    Abstract: A method to adjust an internal combustion engine is described, comprising the steps of: i) controlling a first and second adjustment member so as to adjust a first and second quantity of air in a first and second cylinder provided with a first and second piston; ii) operating a first and second ignition member with a first and second advance angle relative to the first and second top dead centre of the first and second piston; iii) processing a value of one of the amplitudes associated with a respective frequency of a driving member; iv) detecting that the amplitude at a corresponding desired frequency exceeds a threshold value; v) reducing the first advance angle; and vi) increasing the first quantity of air so as to maintain the average value of the resulting torque constant at two complete rotations of said driving member.
