Abstract:
To solve the requirements of collecting the brake pedal displacement data in the driving simulator and locate the brake pedal position accurately, a brake pedal displacement measuring system which consists of two Hall sensors, seven small magnets, one SCM control system was presented, its working principle and realizing method were introduced. The Hall effect principle was used to locate the brake pedal position. The pulse signal was detected and output by Hall sensors, and was sent to the SCM control system after phase reverse and demodulation. The SCM calculated the brake pedal displacement based on the pulse signal. The result proves that the measurement error of the system is less than ±3%, and the measuring performance is stable. It also has the advantages of small dimension and low cost. It can fulfill the requiring of measuring the brake pedal displacement. 9 figs, 6 refs.
