Abstract: This paper introduces a design scheme of a Monitor for Automobile Braking Force of Pedal based on single-chip computer C8051F206, The hardware structure and software program diagram was also studied. This system combines single-chip computer with multi sensor. It can measure parameters of automobile braking force of pedal and hand braking force quickly. The system was driven with menu to select and person-computer interlocutory way by LCD. The measured data and maxima data was displayed on real time. It also has the
communication function by RS232, for the convenience of management by PC, realizes networking management. It has the characteristics of low costs, high accuracy, high stability and high practicability.
Keywords: Single-chip Computer; force of pedal; Monitor
