PROBLEM TO BE SOLVED: To provide a hybrid electric vehicle drive control unit capable of continuing moving in a limp mode at a time of the occurrence of an ON failure of an engagement element.SOLUTION: A hybrid electric vehicle drive control unit comprises: an abnormality determination unit 72 determining abnormality that a clutch CL1 or a brake BK1 cannot be released; an output rotation velocity sensor 40 detecting a vehicle velocity V; and a brake engagement control unit 64 reducing an engagement force of a brake BK2 if the abnormality determination unit 72 determines abnormality that the clutch CL1 or the brake BK1 cannot be released and a vehicle velocity determination unit 74 determines that the vehicle velocity V is lower than a specified threshold. With this configuration, it is possible to appropriately suppress the occurrence of engine stall by allowing the differential rotation of an output gear relating to input rotation from an engine if driving wheels are stopped at a time of an ON failure of the clutch CL1 or the brake BK1.

    【課題】係合要素のON故障時における退避走行を継続可能とするハイブリッド車両用駆動装置の制御装置を提供する。【解決手段】クラッチCL1、ブレーキBK1が解放できない異常を判定する異常判定部72と、車速Vを検出する出力回転速度センサ40と、異常判定部72によりクラッチCL1又はブレーキBK1が解放できない異常が判定され、且つ、車速判定部74により車速Vが規定の閾値未満となったことが判定された場合には、ブレーキBK2の係合力を低下させるブレーキ係合制御部64とを、備えたものであることから、クラッチCL1又はブレーキBK1のON故障時に駆動輪が停止させられる場合に、エンジンからの入力回転に係る出力歯車の差動回転を許可することで、エンジンストールの発生を好適に抑制できる。【選択図】図5
