The invention discloses a method and device for adjusting the torque of a vehicle. The vehicle comprises a first power source and a second power source. The method comprises steps that the first torque outputted by the first power source is obtained; if the first torque is greater than the maximum torque outputted by the first power source, the torque change rate of the second power source is determined as a first rate; if the first torque is smaller than or equal to the maximum torque outputted by the first power source, the torque change rate of the second power source is determined as a second rate; the first rate is smaller than the second rate, namely, when the first torque outputted by the first power source does not reach the maximum torque outputted by the first power source, the change rate of the torque output by the second power source is increased so as to increase the gear shifting speed; when the first torque outputted by the first power source reaches the maximum torqueoutputted by the first power source, the change rate of the torque outputted by the second power source is decreased to optimize the driving comfort, and the driving comfort of the vehicle can be guaranteed on the premise that the gear shifting time is proper.

    本申请公开了一种调节车辆扭矩的方法及装置,该车辆包括第一动力源和第二动力源,该方法包括:获取第一动力源输出的第一扭矩;若第一扭矩大于第一动力源输出的最大扭矩,则确定第二动力源的扭矩变化速率为第一速率;若第一扭矩小于或者等于第一动力源输出的最大扭矩,则确定第二动力源的扭矩变化速率为第二速率;其中,第一速率小于第二速率。即,在第一动力源输出的第一扭矩并未达到第一动力源输出的最大扭矩时,加快第二动力源输出的扭矩的变化速率以加快换挡速度;在第一动力源输出的第一扭矩达到第一动力源输出的最大扭矩时,减慢第二动力源的输出的扭矩的变化速率以优化驾驶舒适性,可以使得换挡时间适宜的前提下保证车辆的驾驶舒适性。
