The invention provides a controller adding an overtaking speed gear, a voice prompter and an electric car. The related electric car with a gear pushing switch is limited by the switch number, generally provided with only three speed or function gears, and is generally one to two gears less than an electric car with a gear jogging switch. For an electric car requiring more gear functions, three gears are not enough. A program is preset in a single chip microcomputer circuit of the controller and used for rotating a rotating handle back and forth for certain times when the rotating handle is rotated to the maximum extent, a speed limit value of the controller is smoothly switched to an overtaking speed value, and the overtaking speed gear can be easily added on the basis of the original three speed or function gears on the condition that no structure of the electric car with the gear pushing switch is changed. The voice prompter is added, and the electric car can be prompted of being in an overtaking speed state through the voice prompter when the electric car is in the overtaking speed state.
