Abstract:
1. A vehicle drive force control apparatus comprising: a main drive source configured and arranged to drive a first wheel; an electric generator configured and arranged to be driven by the main drive source; an electromechanical device configured and arranged to receive electric power from the electric generator; a controller operatively coupled to at least one of the electric generator and electromechanical device, the controller comprising a transmission installed in a torque transmission path between the main drive source and the first wheel driven by the main drive source, the predicting section being configured to predict the acute change in the rotational speed of the main drive source based on detecting a gear shifting indication of the transmission; and the output stabilizing section being further configured to change the field current of the electric generator in advance upon predicting that the transmission will shift to a different gear ratio with the change in the field current of the electric generator being made in accordance with the shift.
