The invention relates to a driving force control device for a hybrid vehicle. Provided is a driving force control device for a hybrid vehicle, the driving force control device being capable of reducing the time from a request for switching a travel range to the start of travel while suppressing a decrease in driving force during reverse travel. Provided is a driving force control device for a hybrid vehicle, in which, when an engine is driving, torque transmitted from the engine to an output member via a transmission mechanism is counteracted with reverse torque output from a second motor, when the transmission mechanism is set in a low mode and a restriction condition for selecting a reverse travel range is satisfied (Yes in steps S1 and S2), a start determination value for determining that the engine is started is changed so that the engine is more difficult to start than when the restriction condition is not satisfied (step S3).
本发明涉及一种混合动力车辆的驱动力控制装置。提供一种能够抑制后退行驶时的驱动力的降低,同时缩短从行驶档的切换请求到行驶开始为止的时间的混合动力车辆的驱动力控制装置。一种混合动力车辆的驱动力控制装置,在发动机正在驱动的情况下,经由传动机构从发动机向输出构件传递的转矩与从第2马达输出的后退转矩对抗,其中,在传动机构设定低模式、且行驶档选择后退行驶档的限制条件成立的情况下(在步骤S1和步骤S2中为Yes),以与限制条件不成立的情况相比发动机难以起动的方式变更判定起动发动机的起动判定值(步骤S3)。
