The invention relates to the field of new energy automobiles, and provides a method and device for regulating and controlling the torque of an accelerator pedal in a single pedal mode. The method comprises the steps that when a target vehicle is in a single-pedal mode and it is determined that an accelerator pedal torque regulation and control function is in an activated state, an accelerator pedal demand torque initial value, an accelerator pedal torque compensation initial value and a target compensation torque intervention coefficient of the target vehicle are determined; based on the accelerator pedal demand torque initial value, the accelerator pedal torque compensation initial value and the target compensation torque intervention coefficient, the current whole vehicle demand torque of the target vehicle is determined; based on the accelerator pedal opening degree and the accelerator pedal opening degree change rate, the whole vehicle torque rising gradient is determined; and the current whole vehicle demand torque is controlled based on the whole vehicle torque rising gradient, so that the accelerator pedal torque of the target vehicle is regulated and controlled. The driving intention of the driver can be fully and accurately recognized, and therefore the driving experience feeling of the driver when the target vehicle is in the single-pedal mode is improved.
