Solution Overview

Problem

Current autonomous vehicle systems fail to identify permissioned parking spaces effectively, especially in dense cities where multiple restrictions and permissions apply, requiring human intervention to navigate and comply with parking laws and regulations.

Innovation Solution

An autonomy controller system that utilizes sensor fusion, including radar, lidar, image, and ultrasound data, to detect and classify objects, combined with map data and parking characteristic information, to autonomously select a collision-free parking path and determine permissioned parking spaces by analyzing signs and restrictions, allowing the vehicle to search for and park in suitable locations without human input.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If autonomous vehicle systems use basic sensor analysis to identify parking spaces, then the system complexity is reduced, but the ability to identify permissioned parking spaces in dense cities with multiple restrictions fails

Engineering Contradiction:
Improveparking permission identification accuracyVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system segments parking restriction identification into multiple classification levels (e.g., disabled parking, loading zones, fire lanes, time-restricted areas). Each restriction type is detected and evaluated independently through separate logical branches in the control system, allowing comprehensive permission verification without overwhelming system complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary processing layer between sensor detection and parking decision-making. This intermediary component analyzes sensor data, cross-references multiple restriction types, and determines permission status before the vehicle commits to a parking space, thereby improving reliability without directly increasing base system complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If human drivers manually identify parking permissions, then parking space selection accuracy is improved, but the need for human intervention increases and automation is reduced

Engineering Contradiction:
Improveparking permission detection accuracyVSAvoidautonomous parking capability
Core Design Contradiction:
Measurement precisionVSExtent of automation

Solution Approach 1:

The autonomous vehicle system performs self-service by autonomously detecting parking restrictions, evaluating permission criteria, and selecting appropriate parking spaces without human intervention. The control system independently processes sensor data, applies permission logic, and executes parking maneuvers, thereby maintaining high detection accuracy while maximizing automation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements feedback loops where sensor data continuously monitors parking restriction signs and conditions, the control system evaluates permission status based on this feedback, and adjusts parking space selection accordingly. This closed-loop approach enables accurate permission detection while maintaining full autonomous operation.

Inventive Principle:
Principle #23Feedback

3Measurement precision

If the vehicle analyzes multiple classes of parking restrictions, then permissioned parking identification accuracy is improved, but the time required to select a parking space increases

Engineering Contradiction:
Improvepermissioned parking identification accuracyVSAvoidparking search time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The control system performs preliminary analysis of parking restrictions by pre-processing sensor data to identify and classify restriction types before making parking decisions. By提前 categorizing restrictions (e.g., disabled, loading, fire lane, time-restricted), the system reduces the computational burden during real-time parking selection, thereby maintaining high identification accuracy while reducing overall search time.

Inventive Principle:
Principle #10Preliminary action

4Measurement precision

If advanced sensor fusion is used to detect parking restrictions, then permission identification accuracy is improved, but the device complexity and computational requirements increase

Engineering Contradiction:
Improverestriction detection accuracyVSAvoidsensor system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent merges multiple sensor types (cameras, LIDAR, radar) into a unified sensor fusion system that collectively detects parking restrictions. By combining the strengths of different sensors—visual recognition from cameras, spatial mapping from LIDAR, and penetration capability from radar—the system achieves high detection accuracy while managing complexity through integrated processing rather than separate independent systems.

Inventive Principle:
Principle #5Merging (Combining)
