To prevent heat-generation control from influencing behavior of a vehicle while performing the control during running of the vehicle.SOLUTION: When executing heat-generation control, a control part of a vehicular driving device controls a first rotary electric machine so that the machine generates first cancelling/driving force and controls a second rotary electric machine so that the machine generates second cancelling/driving force that acts on the opposite side of a running direction of the vehicle with respect to the first cancelling/driving force. In executing the heat-generation control, when required driving force (Trq) is larger than a switching restriction range (SWLim), the control part performs regenerative control of the first rotary electric machine and performs powering-control of the second rotary electric machine, during acceleration of the vehicle, and performs powering-control of the first rotary electric machine and performs regenerative control of the second rotary electric machine, during deceleration of the vehicle. In executing the heat-generation control, when the required driving force is within the switching restriction range (SWLim), the control part keeps on performing the regenerative control or the powering-control of the first rotary electric machine and the second rotary electric machine in the heat-generation control executed in the last minutes, without switching.SELECTED DRAWING: Figure 9
【課題】車両の走行中に創熱制御を行いつつ車両の挙動に影響を与えることを防止すること。【解決手段】車両用駆動装置の制御部は、創熱制御を実行する際、第1打消し駆動力を第1回転電機から発生するように制御し、かつ第1打消し駆動力に対して車両の進行方向の反対側に作用する第2打消し駆動力を第2回転電機から発生させる。創熱制御を実行する際であって要求駆動力(Trq)が切換え制限範囲(SWlim)よりも大きい場合、車両の加速時は第1回転電機を回生制御すると共に第2回転電機を力行制御し、車両の減速時は第1回転電機を力行制御すると共に第2回転電機を回生制御する。創熱制御を実行する際であって要求駆動力が切換え制限範囲(SWlim)の範囲内となった場合、直前に実行していた創熱制御における第1回転電機及び第2回転電機の回生制御又は力行制御を切換えずに継続させる。【選択図】図9
