An acceleration control method for a hybrid vehicle includes: identifying whether a torque limit insufficiency condition is satisfied during a position increase of an accelerator pedal; switching a torque limit of the driving motor from an initial torque limit to a peak torque limit calculated according to a peak discharge power of the battery when it is recognized that the torque limit insufficiency condition is satisfied; identifying whether an exit condition is satisfied after the torque limit of the driving motor is switched to the peak torque limit; when it is recognized that the exit condition is satisfied, the torque limit of the drive motor is switched from the peak torque limit to a continuous torque limit calculated from the continuous discharge power of the battery. The method improves the acceleration response performance of the hybrid vehicle. The invention further relates to an acceleration control device.

    一种用于混合动力车辆的加速控制方法,具体包括:在油门踏板的位置增加期间识别是否满足扭矩限制不足条件;当识别出满足扭矩限制不足条件时,将驱动电机的扭矩限制从初始扭矩限制切换为根据电池的峰值放电功率计算的峰值扭矩限制;在将驱动电机的扭矩限制切换为峰值扭矩限制之后,识别是否满足退出条件;当识别出满足退出条件时,将驱动电机的扭矩限制从峰值扭矩限制切换为根据电池的连续放电功率计算的连续扭矩限制。该方法改善了混合动力车辆的加速响应性能。还涉及一种加速控制装置。
