| description | The invention discloses an accelerator MAP calibration method and system in a single-pedal mode and an electric vehicle. The calibration method comprises the steps that vehicle speeds and accelerated speeds corresponding to all accelerator opening degrees of a sample vehicle in the single-pedal mode are tested and obtained; based on the vehicle speeds and accelerations corresponding to different accelerator opening degrees, the initial acceleration MAP of the finished vehicle is constructed; based on the initial acceleration MAP, determining an initial accelerator MAP of the finished vehicle in combination with finished vehicle information and a motor external characteristic curve; and testing and acquiring the vehicle speed and acceleration corresponding to each accelerator opening degree of the finished vehicle loaded with the initial accelerator MAP in the single pedal mode, evaluating according to the driving comfort, finely adjusting the initial accelerator MAP, acquiring the final accelerator MAP of the |
