The invention provides a driving force control device for a hybrid vehicle, which can suppress the deterioration of emission under the condition that the amount of particles accumulated in a particle filter is small, and can satisfy the required driving force. The electric vehicle is configured so as to switch from the electric motor travel mode to the hybrid travel mode on the basis of the remaining charge amount of the electricity storage device, and when the amount of particles accumulated in the particle filter is less than a predetermined amount (YES in step S2), the amount of particles accumulated in the particle filter is less than the amount of particles accumulated in the particle filter (NO in step S2), and the amount of particles accumulated in the particle filter is less than the predetermined amount (YES in step S2). The remaining charge amount of the power storage device, which is a threshold value for switching from the electric motor travel mode to the hybrid travel mode, is set to be higher (step S7), and the upper limit output of the internal combustion engine during travel in the hybrid travel mode is set to be lower (step S8).
本发明提供一种混合动力车辆的驱动力控制装置,能够抑制堆积在颗粒过滤器内的颗粒的量少的条件下的排放的恶化,并且满足要求驱动力。构成为基于蓄电装置的充电余量从电动机行驶模式向混合动力行驶模式切换,在堆积于颗粒过滤器的颗粒的量小于预先确定的规定量的情况下(步骤S2中为是),与堆积于颗粒过滤器的颗粒的量为规定量以上的情况(步骤S2中为否)相比,将成为从电动机行驶模式向混合动力行驶模式的切换阈值的蓄电装置的充电余量设定得更高(步骤S7),并且将混合动力行驶模式下的行驶时的内燃机的上限输出设定得更低(步骤S8)。
