To prevent erroneous operation on accelerator pedal by car driver due to emergency situations in driving process, combining with the brake and accelerator pedal position, using centrifugal clutch ratchet principle, an automobile safety auxiliary brake system was de- signed. By using Unigraphics NX8 software in assembly mode with the top-down design method, three dimensional entity models were built for all parts of the device, then the structure analysis module was used to determine the force situation of this device under different conditions, and structural strength analysis was carried out....
