Solution Overview

Problem

Current vehicle safety systems do not effectively warn occupants of approaching remote vehicles, particularly in situations where the remote vehicle is not visible due to limited field of view, turns, hills, or obstacles, which can lead to unsafe exit attempts from the host vehicle.

Innovation Solution

A vehicle occupant warning system equipped with a receiver, electronic controller, and mitigation device that uses two-way wireless communications to determine the location, direction, and speed of remote vehicles, preventing occupants from exiting the host vehicle when a remote vehicle is approaching by generating warnings or locking doors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If wireless communication systems are used to detect remote vehicles, then vehicle occupant safety is improved, but device complexity increases

Engineering Contradiction:
Improvevehicle occupant safetyVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The wireless communication system is designed to serve multiple functions: detecting remote vehicles, determining their travel conditions, and triggering mitigation operations. This multi-functionality reduces the need for separate dedicated systems while improving overall safety

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent uses wireless communication signals as an intermediary to transfer information about remote vehicles without requiring direct visual contact or complex optical sensing systems, thereby improving safety while managing system complexity

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If the system monitors remote vehicle travel conditions continuously, then occupant protection is improved, but energy consumption increases

Engineering Contradiction:
Improveoccupant protectionVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system performs preliminary monitoring of remote vehicle travel conditions to assess potential risks before they materialize into immediate threats, allowing for proactive safety measures while managing energy usage through selective continuous monitoring

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system uses feedback from wireless communication data to dynamically adjust monitoring intensity, maintaining high protection levels when risks are detected while reducing energy consumption during low-risk periods through adaptive monitoring strategies

Inventive Principle:
Principle #23Feedback

3Reliability

If the mitigation device prevents occupant exit, then safety is improved, but ease of operation deteriorates

Engineering Contradiction:
ImprovesafetyVSAvoidoccupant exit capability
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system applies preliminary anti-action by preventing occupant exit only when remote vehicle travel conditions indicate an imminent collision risk, rather than continuously restricting movement. This targeted approach maintains safety while preserving ease of operation during normal conditions

Inventive Principle:
Principle #9Preliminary anti-action

Solution Approach 2:

The mitigation device dynamically adjusts its operation based on real-time assessment of remote vehicle travel conditions, transitioning between restricted and unrestricted exit states as conditions change, thereby balancing safety requirements with operational convenience

Inventive Principle:
Principle #15Dynamics

AI summary

A vehicle occupant warning system includes a receiver, an electronic controller and a mitigation device. The receiver is disposed onboard a host vehicle and is configured to receive remote vehicle information representing a travel condition of a remote vehicle. The electronic is controller configured to determine whether the remote vehicle will pass adjacent a side of the host based on the remote vehicle information. The mitigation device is configured to perform a mitigation operation to prevent an occupant of the host vehicle from exiting the host vehicle when instructed by the electronic controller.
