The invention discloses a control device and method for safe switching between parking modes. The control device comprises an angle sensor, a torque sensor, a gear signal detection device, a microprocessor, an LED warning lamp, an EPS motor and a buzzer, wherein signals collected by the angle sensor, signals collected by the torque sensor and signals collected by the gear signal detection device serve as input signals of the microprocessor, and output signals of the microprocessor are transmitted to the LED warning lamp, the EPS motor and the buzzer. When an automobile is in the independent parking mode, the torque sensor judges whether externally-added torque exists or not, and the microprocessor judges whether the independent parking mode needs to be switched to the assistance parking mode or not according to the judgment result of the torque sensor; if switching needs to be carried out, the microprocessor controls the rotating speed of the EPS motor to reduce the rotating speed of a steering wheel, the independent parking mode is safely switched to the assistance parking mode, and the assistance parking mode is carried out until parking is stopped. According to the control device and method for safe switching between the parking modes, the problem that safety accidents are possibly caused due to the fact that a driver touches the steering wheel suddenly in the independent parking mode can be solved.
