==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 ==
1. Improved brake system reliability.
2. Enhanced vehicle safety.
3. Optimal brake performance.

== Potential Commercial Applications ==
"Predictive Brake Booster System for Vehicles" could be used in the development of advanced automotive brake systems.

== Possible Prior Art ==
There may be prior art related to predictive systems for brake boosters in vehicles, but specific examples are not provided in the abstract.

== Unanswered Questions ==
=== How does this system handle variations in driving conditions that may affect brake performance? ===
The abstract does not mention how the system adjusts for different driving scenarios that could impact brake booster pressure predictions.

=== What is the accuracy rate of the negative pressure predictions made by this system? ===
The abstract does not provide information on the accuracy or reliability of the negative pressure predictions generated by the system.


==Original Abstract Submitted==

A system for predicting a negative pressure of a brake booster of a vehicle includes: a driving information detector detecting driving information related to driving of the vehicle; and a controller determining a negative pressure of an intake manifold based on a pressure of the intake manifold and an atmospheric pressure which is the driving information and including a booster negative pressure predictor predicting the negative pressure of the brake booster by integrating over time a change rate according to a charging rate and a discharging rate of the negative pressure determined using a negative pressure of the brake booster determined in a previous cycle according to a logic for predicting the negative pressure of the brake booster and the negative pressure of the intake manifold of a current cycle and an imitated brake pedal force signal of the current cycle imitating an acceleration of the vehicle.
