Two-Wheel Vehicle Protection Control Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle protection systems are inefficient in operating protection devices for occupants of two-wheel vehicles during collisions, as they often fail to accurately determine the second-time collision position, leading to unnecessary or ineffective deployment of protection devices.
Innovation Solution
A protection control apparatus equipped with an object recognizer, first-time collision detector, relative vector estimator, first-time collision position identifier, second-time collision position estimator, operation instructor, and operation device selector, which analyzes the collision dynamics to selectively deploy external protection devices corresponding to the predicted second-time collision position.

Engineering Contradiction Analysis
1Reliability
If protection devices are operated in response to detection of first-time collision with any object, then pedestrian protection is improved, but unnecessary operation occurs when collision object is two-wheel mobile object
Solution Approach 1:
The system segments the collision object recognition into specific categories (pedestrian vs. two-wheel mobile object) and segments the protection device operation into targeted deployments. By identifying the type of collision object and predicting its trajectory, the system selectively operates only the protection devices corresponding to the predicted second-time collision position, avoiding unnecessary operations of other protection devices.
Solution Approach 2:
The system performs preliminary action by predicting the second-time collision position before the actual collision occurs. The trajectory prediction unit estimates where the occupant of the two-wheel mobile object will land based on the collision dynamics, and the protection device is operated in advance at that predicted position, ensuring protection is deployed only where needed.
2Device complexity
If protection device corresponds to fixed region on vehicle, then device structure is simplified, but cannot adapt to varying second-time collision positions of two-wheel vehicle occupants
Solution Approach 1:
The system introduces dynamics by making the protection device operation location adaptive rather than fixed. The trajectory prediction unit calculates the predicted second-time collision position dynamically based on collision parameters, and the protection device is operated at this dynamically determined position. This allows the same protection device to serve multiple regions depending on the collision scenario.
Solution Approach 2:
The system changes parameters by varying the operation position and target region of the protection device based on collision characteristics. Instead of having fixed protection zones, the system adjusts the deployment parameters (position, timing, target area) of the protection device according to the predicted trajectory and collision dynamics, optimizing protection coverage for different collision scenarios.

AI summary
A second-time collision position estimator section estimates a second-time collision position that is a position at which an occupant on a two-wheel mobile object has a second-time collision, based on a relative vector estimated by a relative vector estimator section and a first-time collision position identified by a first-time collision position identifier section. An operation instructor section operates an external protection device, which is determined to be able to protect the occupant on the two-wheel mobile object based on the second-time collision position estimated by the second-time collision position estimator section.
