A Vacuum Booster Model for Brake Pedal Feeling Analysis

Abstract:

The feeling of the brake pedal is one of the most important factors for the driver confidence during brake. Vacuum booster plays a significant role on the brake pedal feeling analysis. The traditional characteristic model cannot satisfy our objective, so a model based on the structure is needed. This paper presents a model based on the structure defined as 3 springs, 2 valves, 1 reaction washer and dynamic air flows, gives out the detailed condition to judge for the states of vacuum booster which can give more details to the brake pedal feeling. After simulation, the conclusion that the model is proper for pedal feeling can be drawn.
