Abstract: A method to control an active shock absorber of a road vehicle. The active shock absorber is part of a suspension connecting a frame of the road vehicle to a hub of a wheel and has: a first element, which defines an end of the active shock absorber, a second element, which defines another end of the active shock absorber and is mounted so as to slide relative to the first element; and an actuator, which is configured to generate a force, which is applied between the two elements. The control method comprises the steps of: determining a vertical acceleration of the hub; determining a speed of translation between the two elements of the active shock absorber; determining a target force for the actuator of the active shock absorber based on the vertical acceleration of the hub and based on the speed of translation between the two elements of the active shock absorber; and controlling the actuator (10) of the active shock absorber so as to pursue the target force.

Abstract: A method to control, while driving along a curve, a road vehicle with a variable stiffness and with rear steering wheels. The method comprises the steps of: determining an actual attitude angle of the road vehicle; establishing a desired attitude angle; determining an actual yaw rate of the road vehicle; establishing a desired yaw rate; and changing, in a simultaneous and coordinated manner, the steering angle of the rear wheels and the distribution of the stiffness of the connection of the four wheels to the frame depending on a difference between the actual attitude angle and the desired attitude angle and depending on a difference between the actual yaw rate and the desired yaw rate.

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: According to the control method, the power/torque that can be supplied by an electric drive motor in a vehicle is handled by setting and adjusting a maximum available level for the power/torque that can actually be supplied; the adjustment includes a reduction of the maximum available level from a peak value to a nominal value after the electric drive motor has supplied an actual power/torque equal to said peak value for a predetermined amount of time.
