The invention provides a method and device for controlling motor working states and an automobile, and relates to the field of automobile control. The method and device for controlling the motor working states and the automobile are used for solving the problem of safety accidents caused by unconformity of a real-time feedback state of a motor and a driver intended gear. The method for controlling the motor working states includes the steps of obtaining an accelerator pedal signal, a braking pedal signal, a driver intended gear and a motor working state in a preset period; determining a to-be-executed working state of the motor in a next period following the preset period according to the accelerator pedal signal, the braking pedal signal, the driver intended gear and the motor working state of the automobile in the preset period; obtaining a real-time working state of the motor in the next period following the preset period; and controlling the working state of the motor according to the to-be-executed working state and the real-time working state. By adopting the method and device for controlling the motor working states and the automobile, whether the real-time working state of the motor and the driver intended gear are consistent or not can be determined, and thus the effect that the safety accidents are avoided can be achieved.
