Solution Overview

Problem

Autonomous vehicles often operate at speeds or configurations that exceed human comfort levels due to their advanced sensor capabilities, leading to passenger discomfort and potential interference with the driving system, which negatively impacts the user experience.

Innovation Solution

A system that determines a recommended operational configuration for autonomous vehicles based on occupant vision capability information, comparing user-defined comfort levels with maximum vehicle capabilities using sensors and contextual data to adjust speed and other parameters, providing a more humanized driving experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If autonomous vehicles operate at maximum speed based on sensor capabilities, then vehicle productivity is improved, but passenger comfort deteriorates due to exceeding human visual comfort levels

Engineering Contradiction:
Improvevehicle speedVSAvoidpassenger discomfort
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system dynamically adjusts the vehicle's operational parameters (speed, acceleration) based on the determined comfortable configuration. The processor modifies these parameters in real-time to match what the occupant would visually comfortably operate at, resolving the contradiction between maximum productivity and passenger comfort.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system uses feedback from the determined comfortable operational configuration to continuously adjust vehicle operation. By comparing the comfortable configuration against maximum capabilities and using this feedback loop, the system maintains optimal speed that satisfies both productivity requirements and passenger comfort levels.

Inventive Principle:
Principle #23Feedback

2Productivity

If autonomous vehicles operate at maximum speed based on sensor capabilities, then vehicle productivity is improved, but user experience deteriorates due to anxiety and potential interference with driving system

Engineering Contradiction:
Improvevehicle speedVSAvoiduser experience
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The system changes operational parameters to align with user comfort levels. By determining the comfortable operational configuration based on occupant vision capability and adjusting speed accordingly, the system improves user experience while maintaining acceptable productivity through optimized rather than maximum speed operation.

Inventive Principle:
Principle #35Parameter changes

3Measurement precision

If vehicle operates based on maximum sensor visibility, then measurement precision is improved, but adaptability deteriorates because it cannot adjust to individual occupant vision capabilities

Engineering Contradiction:
Improvesensor visibilityVSAvoidoccupant vision capability adjustment
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The system applies local quality by tailoring the operational configuration to the specific occupant's vision capabilities rather than using a uniform maximum sensor visibility approach. The comfortable operational configuration is locally adapted to each occupant's visual field and vision capability, allowing the vehicle to operate at speeds appropriate for that specific user while still leveraging the sensor system's measurement precision.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system changes operational parameters based on individual occupant characteristics. By determining vision capability information specific to each occupant and adjusting the comfortable operational configuration accordingly, the system achieves both measurement precision from sensors and adaptability to individual users through dynamic parameter modification.

Inventive Principle:
Principle #35Parameter changes
