The present invention provides a drive control device for a hybrid vehicle, which can suppress backward movement of the vehicle even when engine torque cannot be transmitted to drive wheels when a large load acts in the direction opposite to the traveling direction of the vehicle. The drive control device for a hybrid vehicle is configured so as to determine whether or not there has occurred a failure in which torque corresponding to the required driving force cannot be transmitted from the engine to the first driving wheel when propulsion travel is performed by transmitting torque from the engine to the first driving wheel on a travel path on which a load for retreating the hybrid vehicle is applied (step S3), and when the failure has occurred, bringing the engagement mechanism into a released state (step S5), and executing reverse avoidance control for transmitting a requested torque corresponding to the requested driving force from the motor to the second drive wheel is executed (step S8 or step S9).

    本发明提供即使在向与车辆的行进方向相反的方向作用大的载荷的状况下无法将发动机转矩向驱动轮传递的情况下也能够抑制车辆后退的混合动力车辆的驱动控制装置。构成为,在作用使混合动力车辆后退的载荷的行驶路上从发动机向第一驱动轮传递转矩而进行推进行驶时,判断是否发生了无法将与要求驱动力相当的转矩从发动机向第一驱动轮传递的失效(步骤S3),在发生了失效的情况下,使卡合机构成为释放状态(步骤S5),且执行从电动机向第二驱动轮传递相当于要求驱动力的要求转矩的后退避免控制(步骤S8或步骤S9)。
