Solution Overview

Problem

Autonomous vehicles lack an effective system to detect approaching objects, which poses a safety risk for passengers exiting the vehicle, as they may not be aware of incoming cyclists or vehicles at high speeds.

Innovation Solution

An object approaching detection system that utilizes sensors such as camera, LIDAR, and RADAR to identify potential hazards and prevent passenger exit by locking doors or providing warnings when an object is detected within the exit zone.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If autonomous vehicles allow passengers to exit freely without detection systems, then ease of operation is improved, but passenger safety deteriorates due to undetected approaching objects

Engineering Contradiction:
Improvepassenger exit convenienceVSAvoidpassenger safety
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary detection of approaching objects using sensors (camera, LIDAR, RADAR) before the passenger exits the vehicle. The control system proactively locks the passenger door or provides warnings before the hazardous situation occurs, preventing the need for reactive safety measures after a threat is detected.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The control system acts as an intermediary between the sensor system and the passenger door. It receives data from sensors detecting approaching objects, processes this information, and automatically intervenes by locking the door or alerting the passenger, thereby mediating between the passenger's exit intent and the safety hazard.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If sensors and detection systems are added to detect approaching objects, then passenger safety is improved, but device complexity increases

Engineering Contradiction:
Improvepassenger safetyVSAvoiddetection system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent leverages sensors (camera, LIDAR, RADAR) that are already part of the autonomous vehicle's navigation and obstacle detection system. By repurposing these existing multi-functional sensors for the additional function of detecting approaching objects near the vehicle, the system avoids adding dedicated single-purpose sensors, thereby reducing overall system complexity.

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

Solution Approach 2:

The control system utilizes the autonomous vehicle's existing sensor infrastructure and processing capabilities to perform the additional safety function. The system serves itself by using its own navigation sensors to detect hazards that would otherwise require separate dedicated detection equipment.

Inventive Principle:
Principle #25Self-service

3Reliability

If the system locks passenger doors to prevent exit when objects are detected, then passenger safety is improved, but loss of time occurs due to delayed exit

Engineering Contradiction:
Improvepassenger safetyVSAvoidpassenger exit time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The passenger door locking status is dynamically adjusted based on real-time sensor data. The door remains unlocked and accessible when no approaching objects are detected, but automatically locks only when sensors detect objects within the hazardous exit zone. This dynamic response ensures safety only when necessary, minimizing unnecessary delays.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system continuously monitors sensor data providing feedback to the control system about approaching objects. When objects are detected within the exit zone, the control system receives this feedback and automatically locks the door or provides warnings. The system continuously updates its state based on changing conditions, allowing the door to unlock again when the hazard is removed.

Inventive Principle:
Principle #23Feedback

AI summary

Systems, methods, and computer-readable media are provided for detecting whether an object is approaching an autonomous vehicle when a passenger is about to exit the autonomous vehicle, determining a speed and type of the object that is approaching the autonomous vehicle, determining whether the object will enter an exit zone when the passenger enters the exit zone based on the speed and the type of the object that is approaching the autonomous vehicle, and preventing the passenger from exiting the autonomous vehicle based on the determining of whether the object will enter the exit zone when the passenger enters the exit zone.
