  • Patent number: 11655789
    Abstract: A method of controlling a pickup manoeuvre of a hybrid vehicle is actuated with an engine off, an electric motor active and a first clutch being open. In a first phase of the manoeuvre, vehicle advancement is obtained by progressively closing the second clutch so that the input shaft is set in rotation with an increasing speed, while the motor rotates at an increasing speed higher than a speed of the input shaft with the second clutch in a slip condition. Upon a request for starting the engine, the first clutch is progressively closed so that the engine starts to be driven by the motor, while the second clutch is kept in the slip condition, which is maintained until the engine and motor rotate substantially at a same speed, higher than the speed of the input shaft, and once this condition is reached, closing of the second clutch is started.

  • Patent number: 11535236
    Abstract: A method of controlling a vehicle hybrid propulsion system is provided. The propulsion system includes an internal combustion engine, first and second clutches, an electric motor, and a gearbox having an input shaft and an output shaft connected to drive wheels. The method includes a first operating mode of starting the engine by the motor, a second operating mode of actuating a gear shift, and a third operating mode which actuates starting of the engine and the gear shift. The method includes passing from the first to the third operating modes even if starting of the engine has not been completed, or passing from the second to the third operating modes even if actuation of the gear shift has not been completed, so that the transition from one operating mode to another can be freely actuated at any time, depending upon operating conditions of the hybrid propulsion system.
