Mobile Object Control Device Contact Likelihood Determination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile object control devices may malfunction due to recognition inaccuracies or errors, leading to inappropriate control of mobile objects, such as vehicles, in situations where contact with other objects is predicted.
Innovation Solution
A mobile object control device that includes a recognizer to assess the surroundings, a contact likelihood determiner to evaluate the probability of future contact based on object states, and an unavoidable contact determiner to decide on necessary protective measures, such as activating occupant protection systems, by analyzing the trajectories of both the mobile object and other vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the recognizer is used to detect objects around the mobile object, then the ability to detect contact with objects is improved, but recognition inaccuracies or errors may cause malfunction of protective devices
Solution Approach 1:
The system continuously monitors the state of objects and repeatedly executes determination at predetermined cycles. The contact likelihood determiner receives feedback from the recognizer and adjusts the condition for determining contact likelihood based on the state of the object, creating a closed-loop system that improves reliability despite recognition inaccuracies.
Solution Approach 2:
The system performs preliminary determination of contact likelihood before actual contact occurs. By evaluating the state of the object and predicting future contact probability, the system prepares protective measures in advance while verifying conditions multiple times to ensure accuracy before activation.
2Reliability
If the condition for determining contact likelihood is made strict, then false positives are reduced, but the system may fail to detect actual contact risks
Solution Approach 1:
The condition for determining contact likelihood is not fixed but dynamically adjusted based on the state of the object. The contact likelihood determiner changes the condition according to object characteristics, allowing the system to be more sensitive when appropriate and more conservative when necessary, balancing detection accuracy with risk coverage.
Solution Approach 2:
The system changes parameters related to contact likelihood determination based on the recognized state of the object. By adjusting determination thresholds and conditions according to object state, the system maintains high reliability while ensuring actual contact risks are not missed.
3Reliability
If the protective device is activated frequently to ensure safety, then occupant protection is improved, but unnecessary protective measures cause inconvenience and resource waste
Solution Approach 1:
The system uses continuous feedback from repeated determinations to verify contact likelihood before activating protective devices. By requiring multiple confirmations of the contact condition, the system ensures high reliability while minimizing false activations that would waste energy and inconvenience occupants.
Solution Approach 2:
The system performs preliminary verification of contact likelihood conditions before activating protective measures. By evaluating object state and predicting contact probability in advance with multiple determination cycles, the system activates protection only when truly necessary, balancing safety with resource efficiency.
