A method of performing an electric shift assist in a non-powershift transmission of a hybrid powertrain (100, fig 1), comprising a motor-generator electric unit (500), an internal combustion engine 110, a clutch 700 and a non-powershift gearbox 710. While the clutch 700 is pressed, the method comprises the following steps: comparing a speed of the internal combustion engine 110 with the speed of a gearbox primary shaft 720 and if they are different, actuating the motor-generator electric unit (500), to increase or decrease the internal combustion engine 110 speed, comparing the speed of the primary shaft of the gearbox 720 with the internal combustion engine 110 speed and repeating the previous step until they are equal. Reference is also made to a hybrid powertrain configured to carry out the method, a computer program product on which a computer program for carrying out the method is stored. Also claimed are control apparatus comprising a computer program stored in a memory system (460) connected to an electronic control unit (450) and an electromagnetic signal representing the computer program. |
