Performance Optimization of Bias Bar-Type Brake System Using Data Acquisition System (DAQ)

The key factor involved in the proper functioning of brake system of a vehicle with dual master cylinder is brake biasing. In order to accomplish this, a bias bar with spherical bearing is used to set correct biasing of the hydraulic system which is actuated with single brake pedal. We have done the practical simulation of bias bar system in our BAJA SAE vehicle by using a self-designed DAQ system to measure the pedal effort and the corresponding brake pressure. The optimal position of the bias bar is experimentally validated based on the various positions of the spherical bearing in the pedal housing to obtain locking of all wheels using minimal pedal effort by using real-time data values.
