Abstract:
1. A method for operating a hybrid vehicle having at least a first drive unit and a second drive unit, comprising: one of: (i) starting the idle first drive unit, during driving of the hybrid vehicle, by transferring part of a torque of the operating second drive unit to the first drive unit; or (ii) stopping the operating first drive unit, during the driving of the hybrid vehicle, by interrupting a transfer of a torque from the first drive unit to the second drive unit; wherein the torque of the second drive unit is influenced by at least one variable derived from longitudinal movement of the hybrid vehicle; wherein the at least one of the variables derived from the longitudinal movement of the hybrid vehicle is determined by measuring at least one of (i) a wheel rotational speed, (ii) a wheel rotational acceleration, (iii) a longitudinal velocity of the vehicle, and (iv) a longitudinal acceleration of the vehicle.
