When the car is running, the control system realizes the process of high frequency drive motor to control flywheel energy releasing, the brake energy recovery, pressure detection and temperature detection. Mainly based on 51 single chip control system design, Including UHF drive motor SPWM speed control, vacuum pump pressure control, temperature detection control and so on, the whole control process of Ultra high speed flywheel work needs speed regulation circuit, a pressure detecting circuit, and a temperature detection circuit to realize the related control, For each control process, Write control program, according to the procedure, combining with the simulation software to realize the process of each part of the 51chip simulation. The control of Ultra high speed flywheel achieves the whole system work process, Using the flywheel energy release to less engine power output and using the flywheel to recovery brake energy when the car is braking, saving energy and decrease emission when the car is running. So the ultra high speed flywheel is a major development of future in the application of the car. Keywords: Ultra high speed flywheel; Control system; Circuit; Single
