A drivetrain according to claim 6, in which the predetermined threshold of the accelerator control CA is proportional to the vehicle speed. 8. A drivetrain according to claim 6, in which the electrical energy absorption device comprises a means for storing the electrical energy. 9. A drivetrain according to claim 8, in which the control device tends first of all to empty the electrical energy storing means in the event of a demand for acceleration of the vehicle indicated by the accelerator control CA, before acting on the actuator PP. 10. A drivetrain according to claim 1, in which the control device for controlling the actuator PP continuously calculates, at each iteration, a limit position as follows: Throttle position limit=Max. throttle position-k*(Pthd-Pa-Pt). 11. A drivetrain according to claim 1, in which the unit for controlling the propulsion torque of the vehicle calculates the desired torque in accordance with a chosen sampling period.
