An electrically controlled pneumatic surge prevention device includes a controller (7), an air filter (1), a turbocharger (2), an intercooler (3), a throttle valve (5), air pipes (9), an electromagnetic valve (6) connected using signals to the controller (7), and a surge prevention valve (4) connected to the electromagnetic valve (6). The surge prevention valve (4) is connected to a sixth pipe (96) connecting the intercooler (3) and the throttle valve (5) via a fourth air pipe (94). The electromagnetic valve (6) is arranged at a third air pipe (93), and the surge prevention valve (4) is connected to a second air pipe (92) connecting the air filter (1) and the turbocharger (2) via the third air pipe (93). Also provided is a control method of an electrically controlled pneumatic surge prevention device. In the electrically controlled pneumatic surge prevention device and the control method, electrically controlled pneumatic surge prevention is implemented by adding the surge prevention valve (4) at a front end of the throttle valve (5) and an air input end of the turbocharger (2), and by utilizing the controller (7) to control the surge prevention valve (4). The embodiments are utilized to provide effective and reliable surge prevention and to reduce costs.
