Vehicle Brake Control Apparatus Maintaining Pressure During Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle brake apparatuses face limitations in reducing braking force loss and providing a stable braking sense to drivers, particularly during automatic braking scenarios, which can increase the risk of collisions.
Innovation Solution
A vehicle brake control apparatus that includes a detector to monitor automatic brake control pressure, a determination unit to identify the automatic brake release time, and a braking force maintenance unit to maintain the braking force until the driver's brake control pressure matches the automatic brake control pressure, using a controller to manage the braking force and release accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the conventional automatic brake apparatus supplies driver brake control pressure information after automatic brake release, then the automatic braking can be released, but the braking force loss increases and stable braking sense cannot be provided to the driver
Solution Approach 1:
The patent maintains the automatic brake control pressure information in advance during the automatic brake release time period, before the driver's brake control pressure information becomes the same state. This preliminary maintenance of braking force prevents the loss of braking force that would otherwise occur during the transition period, while also providing stable braking sense to the driver throughout the release process.
2Ease of operation
If the automatic brake control pressure is decreased after automatic brake release time, then the automatic braking is released, but the braking force becomes unstable and driver control is compromised
Solution Approach 1:
The patent uses the detector to continuously obtain automatic brake control pressure information and compares it with the driver's brake control pressure information. The controller maintains the automatic brake control pressure information during the release time period until the driver's input matches, creating a feedback mechanism that ensures braking force consistency while allowing smooth transition to driver control.
Solution Approach 2:
The patent introduces an intermediary maintenance period where the automatic brake control pressure information is held constant during the automatic brake release time. This intermediary state acts as a buffer between the automatic braking phase and the driver-controlled phase, ensuring stability and preventing abrupt changes in braking force.
3Speed
If the automatic brake apparatus releases braking force immediately after automatic brake release time, then the system responds quickly, but the risk of collision increases due to insufficient braking force maintenance
Solution Approach 1:
The patent maintains the automatic brake control pressure information in advance during the automatic brake release time period, ensuring that braking force is preserved until the driver's brake control pressure information becomes the same state. This preliminary maintenance prevents premature release that could lead to collision, while still enabling timely transition to driver control.

AI summary
Disclosed herein is a vehicle brake control apparatus, and a brake control method thereof. The vehicle brake control apparatus includes a detector configured to detect automatic brake control pressure information when an automatic brake apparatus performs an automatic braking by using the automatic brake control pressure information as closing to a current object, and releases the automatic braking; a determination unit configured to determine whether it is a first state in which a present time of detected automatic brake control pressure information is an automatic brake release time; a braking force maintenance unit configured to maintain the automatic brake release time of the automatic brake control pressure information, when it is determined to be the first state, until driver brake control pressure information of a pedal, which is stepped by a driver, becomes the same state as the automatic brake control information; and a controller configured to deliver a command of maintaining braking force to the braking force maintenance unit so as to receive the automatic brake control pressure information and the driver brake control pressure information, and so as to maintain the automatic brake release time of the automatic brake control pressure information until the driver brake control pressure information becomes the same state as the automatic brake control pressure information.
