High Pressure Brake Sensing Technology (Automotive)
Brake pressure sensing is used in the dynamic brake control (DBC) systems of vehicles to improve brake effectiveness in emergency stop situations. When an emergency stop is initiated, the brake pressure will thus be distributed to the wheels of the vehicle in such a way that its directional stability is maintained. This mechanism also helps to ensure directional stability when braking while the vehicle is cornering.
A brake pressure sensor records the magnitude and speed of the brake pressure change and then communicates these values to the DBC control unit. The control unit subsequently compares these values to its stored DBC activation thresholds. The DBC will activate only if certain predefined criteria are met. Conversely, the DBC will deactivate when the driver releases the brake pedal or if the vehicle slows down below a minimum speed.
