Solution Overview

Problem

Conventional navigation systems in autonomous vehicles focus solely on efficient movement to a destination, neglecting the user experience and the ability for occupants to engage in activities during the journey.

Innovation Solution

A route providing method and apparatus that utilizes behavior information and time input from occupants to recommend routes that allow for delayed arrival at a destination, enabling occupants to perform tasks or enjoy activities within the vehicle.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the vehicle follows the shortest distance route or least cost route, then the movement efficiency is improved, but the user experience and ability for occupants to engage in activities during the journey deteriorates

Engineering Contradiction:

Improvemovement efficiencyVSAvoiduser experience

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The navigation system dynamically adjusts the route based on real-time occupant behavior information and requested delay time. Instead of providing a fixed shortest route, the system calculates alternative routes that accommodate occupant needs for activities during the journey, making the route selection adaptive and flexible rather than static and efficiency-only

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the routing parameters from purely distance-based or cost-based optimization to include time-based optimization with delay considerations. By incorporating behavior information and delay time requests as new parameters, the system transforms the route calculation from a single-objective problem to a multi-objective problem that balances efficiency with user experience

Inventive Principle:

Principle #35Parameter changes

2Loss of time

If the vehicle arrives at the destination as quickly as possible, then the travel time is reduced, but the occupant's ability to perform tasks or enjoy activities deteriorates

Engineering Contradiction:

Improvetravel timeVSAvoidactivity duration

Core Design Contradiction:

Loss of timeVSDuration of action of moving object

Solution Approach 1:

The system performs preliminary analysis of occupant behavior information and delay time requests before finalizing the route. By anticipating the occupant's need for activity time and calculating appropriate delay routes in advance, the system ensures that activity duration requirements are met while minimizing unnecessary travel time extension

Inventive Principle:

Principle #10Preliminary action

3Device complexity

If the navigation system provides only efficient routes, then the route calculation simplicity is maintained, but the system's ability to accommodate occupant behavior and delay requests deteriorates

Engineering Contradiction:

Improveroute calculation complexityVSAvoidbehavior accommodation capability

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The navigation system is designed with multi-functionality to handle both traditional efficient routing and new behavior-accommodating routing. The same route calculation engine that optimizes for distance and cost is extended to also optimize for time delay and activity accommodation, allowing a single system to serve multiple purposes without requiring separate complex subsystems

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A computer implemented method and apparatus provide a route to postpone or delay arrival of a vehicle at a destination. The method includes: obtaining, by a processor, behavior information indicating a behavior of an occupant in the vehicle; receiving, by the processor from the occupant, time information for postponing arrival of the vehicle at the destination; and providing, by the processor, at least one recommended route according to the behavior information and the time information.
