Vehicle Braking Control for Collision Range-Based Brake Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing braking control systems may increase the probability of collision when performing a braking operation, especially in situations where decelerating the vehicle could lead to a higher collision risk, such as when another vehicle is likely to collide with a specific area at the rear end of the own vehicle.
Innovation Solution
A braking control apparatus that acquires information on objects around the vehicle, calculates a collision range including a collision point, and determines whether to perform a braking operation based on the positional relationship between the collision range and a predetermined braking-unrequired range, thereby avoiding situations where braking would increase the collision probability.

Engineering Contradiction Analysis
1Measurement precision
If a single collision point is used for braking determination, then the control logic is simple, but the prediction accuracy of collision positions is insufficient
Solution Approach 1:
The patent segments the collision prediction from a single point to a range of multiple points. Instead of determining one collision point, the system calculates a collision range that includes multiple potential collision points. This segmentation improves prediction accuracy by accounting for the uncertainty and variability in actual collision locations.
Solution Approach 2:
The patent transitions from one-dimensional collision point determination to a more comprehensive collision range assessment. By introducing the concept of collision range with multiple points, the system adds dimensional complexity to the prediction model, enabling more accurate representation of potential collision scenarios.

AI summary
A braking control apparatus for controlling a braking operation for an own vehicle is configured to: acquire information on an object detected around the own vehicle; calculate, when a collision between the own vehicle and the object is predicted based on both an estimated route of the object estimated based on the acquired information on the object and an estimated route of the own vehicle, a collision range in the own vehicle at a collision timing between the own vehicle and the object or a collision range in the object at the collision timing; and control, according to a positional relationship between a predetermined braking-unrequired range in the own vehicle and the calculated collision range in the own vehicle or a positional relationship between a predetermined braking-unrequired range in the object and the calculated collision range in the object, whether to perform the braking operation for the own vehicle.
