SYSTEM AND METHOD FOR PREDICTING NEGATIVE PRESSURE OF BRAKE BOOSTER OF VEHICLE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18509028 titled 'SYSTEM AND METHOD FOR PREDICTING NEGATIVE PRESSURE OF BRAKE BOOSTER OF VEHICLE

Simplified Explanation

The patent application describes a system for predicting negative pressure in a brake booster of a vehicle by integrating over time a change rate according to a charging rate and a discharging rate of the negative pressure. This prediction is based on driving information related to the vehicle's operation, such as the pressure of the intake manifold, atmospheric pressure, and an imitated brake pedal force signal.

  • Driving information detector: Detects driving information related to the vehicle's operation.
  • Controller: Determines negative pressure of the intake manifold based on pressure readings and atmospheric pressure, and includes a booster negative pressure predictor.
  • Booster negative pressure predictor: Predicts negative pressure of the brake booster by integrating over time a change rate based on charging and discharging rates of the negative pressure.

Potential Applications

This technology could be applied in the automotive industry for improving brake system performance and safety.

Problems Solved

1. Predicting negative pressure in the brake booster accurately. 2. Enhancing overall brake system efficiency.

Benefits
