Lab VIEW and PID Action-Based Brake Lever Effect for Validation of Servo Vacuum Booster

A servo vacuum, equally termed as power booster or power brake unit, utilizes vacuum to maximize the pedal action of the drivers and consequently to the master cylinder. In manufacturing of this equipment, companies have established several strategies. Such methods are designed to eliminate the potential defects, failure, or malfunction of the system. Therefore, an effective approach, Laboratory Virtual Instrumentation Engineers’ Workbench (Lab VIEW) and Proportional Integral Derivative (PID) based real-time verification of servo vacuum booster is built to avoid failures in component testing in order to exclude components or parts that do not meet the required or defined requirements. The objective of this work is to test the servo booster using the already saved standard measures for an effective servo booster. A Lab VIEW simulation system to track servo vacuum booster output was developed. The pedaling motion is provided using the servo motor, operated by means of the control signal from PID controller, in real time to check the vacuum booster. The checked servo vacuum booster in the specified range is finally ready to mount in vehicles.
