In the setting of the new energy vehicle, the opening degree of an accelerator pedal is changed to change the size of a Hall value, the Hall value formed by the opening degree of the accelerator pedal is input into a VCU system of a central control unit of the new energy vehicle, and the VCU system of the central control unit of the new energy vehicle changes the Hall value output for acceleration through the method for correcting the mistaken stepping of the accelerator pedal, so that the acceleration speed of the vehicle is changed.
A method for correcting the mistaken stepping of an accelerator pedal comprises the following steps,
(1) when leaving a factory, inputting vehicle running information of a vehicle, namely setting parameters (including a driving mode and a relation between Hall values output in a corresponding driving mode state and Hall values formed by accelerator opening degrees) of a VCU (central control unit) of the new energy vehicle, so as to facilitate subsequent control of vehicle acceleration;
(2) the user selects a driving mode of the vehicle according to the requirement;
(3) the system controls acceleration by changing the output Hall value through a central control unit VCU of the new energy vehicle according to a driving mode and an actual input Hall value formed by stepping on an accelerator by a user;
(4) and voice prompt is given in the acceleration process, and the voice prompt is given to a driver, so that psychological hint is provided for acceleration of a user.

and (3.4) if the variation is not larger than the variation deviation value, the Hall value output by the system for acceleration is consistent with the actual Hall value.
In a normal state, if a driver is in a crisis state, the driver is easy to greatly step on a brake (accelerator), namely a brake (accelerator) pedal of a vehicle is in a large opening and closing state, so that the variation of a Hall value in unit time is large; and (3.1) to (3.4) are used for judging whether the vehicle is in a violent acceleration state, namely, when the variation of the Hall value is overlarge, the system automatically changes the Hall value output by the system according to a corresponding coefficient set by the system, so that the situation that the accelerator is stepped on by mistake in a high-speed driving mode state can be prevented, and the safety of the vehicle is further improved.
