It is that Authorization Notice No. is with the maximally related technology of the present invention in vehicle brake system pedal gear relevant information
The patent of invention of CN101982356B --- automobile brake pedal mechanism and its pedal sense simulator and Authorization Notice No. are
A kind of utility model patent of CN201989768U --- brake pedal apparatus of automobile line control brake system.Foregoing invention uses
Pedal displacement sensor identifies the braking intention of driver, is hindered using magnetorheological fluid variable damp characteristics dynamic regulation brake pedal
Buddhist nun's power, improves brake pedal feel and automobile brake perfrmance.Foregoing invention uses piezoelectric type pedal pressing force sensor and pedal
Linear displacement transducer identifies the braking intention of driver jointly, and pedal sense analog functuion part uses dual spring mechanism,
When middle small intensity is braked, only outer lateral spring works；In high-intensitive or emergency braking, medial and lateral spring simultaneously participates in work
Make.But magnetorheological fluid formula pedal sense simulator and piezoelectric type pedal pressing force sensor in foregoing invention etc. in foregoing invention,
All there is the problems such as structure is complicated, controls cumbersome, higher cost and realizes difficulty, and does not both account for braking intention and know in advance
Other and emergency brake function.To so far, the adjustable pedal with braking intention pre-identification and emergency brake function is felt
Simulator and its automobile brake pedal mechanism, which also rarely have, to be referred to.
