Abstract
A brake pedal emulator that produces a pedal characteristic not unlike conventional vacuum or hydraulic brake systems. The system includes an emulator housing, a damper positioned within the emulator housing, a shaft that is slidably received by the emulator housing, and a sequential spring system within the emulator housing in operable contact with the shaft. When a brake pedal force is manually applied, the sequential spring system compresses thereby providing a spring force, which in conjunction with the dynamic dampening force produced by the damper generates the desirable reaction force.
Claims21
A brake pedal emulator system comprising:
- an emulator housing;
- a damper positioned within and operably attached to the emulator housing;
- a shaft that is slidably received within the emulator housing;
- and
- a sequential spring system positioned within the emulator housing and in operable contact with the shaft wherein the shaft compresses said sequential spring system while the damper exerts a dynamic dampening force against a movement of the shaft.
A method of operating a brake pedal emulator system comprising:
- applying a brake pedal force results in transmission of said force to a shaft slidably received by an emulator housing;
- sequentially compressing a plurality of springs within the emulator housing;
- and
- generating a dynamic dampening force from a dampening member positioned within the emulator housing against the shaft while the plurality of springs are being sequentially compressed.
A brake pedal emulator system comprising;
- means for applying a brake pedal force that results in transmission of said force to a shaft slidably received by an emulator housing;
- means for sequentially compressing a plurality of springs within the emulator housing;
- and
- means for generating a dynamic dampening force from a dampening member positioned within the emulator housing against the shaft while the plurality of springs are being sequentially compressed.
