The invention discloses a virtual opening degree determination method, device and equipment of an accelerator pedal and a storage medium, and relates to the technical field of vehicles, and the method comprises the steps that a reference opening degree is determined according to the actual opening degree of the accelerator pedal of the vehicle; determining an actual torque corresponding to the actual opening and a reference torque corresponding to the reference opening based on the maximum opening of the accelerator pedal and the maximum torque when the driving motor operates based on the current rotating speed; determining a torque sequence according to the actual torque and the reference torque, determining the system efficiency corresponding to each intermediate torque in the torque sequence, and determining the intermediate torque corresponding to the maximum system efficiency as a target torque; and the ratio of the target torque to the maximum torque is determined as the virtual opening degree corresponding to the actual opening degree. According to the technical scheme, virtualization processing of the opening degree of the accelerator pedal is achieved, and in addition, when the vehicle runs based on the virtual opening degree, the target torque corresponds to the maximum system efficiency, and therefore optimization of energy consumption of the whole vehicle is achieved while virtualization processing of the opening degree of the accelerator pedal is conducted.
