Solution Overview

Problem

Existing vehicle start operation delay notification systems do not account for individual driver preferences, leading to uncomfortable notifications that disrupt the driver's preferred timing.

Innovation Solution

A device that utilizes passenger, driving environment, and learning value information to set personalized notification timings for start operation delays, incorporating variables to determine the optimal time for notifying the driver.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If detailed customization settings are provided for notification timing, then the notification can be precisely tailored to driver preferences, but the complexity of the system increases and may hinder actual customization by the driver

Engineering Contradiction:
Improvenotification timing customizationVSAvoidcustomization setting complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system automatically learns and adapts to the driver's preferred notification timing through continuous monitoring of start operation patterns, eliminating the need for manual customization settings. The notification device serves itself by autonomously determining optimal timing based on learned driver behavior, thus resolving the contradiction between adaptability and complexity.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system dynamically adjusts notification timing parameters based on learned driver preferences and current driving conditions. By changing the timing parameter adaptively rather than requiring fixed manual configuration, the system achieves high adaptability without exposing complex customization interfaces to the driver.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If notification timing is fixed based on standard algorithms, then the system is simple to operate, but it does not account for individual driver preferences and causes discomfort

Engineering Contradiction:
Improvenotification system operationVSAvoiddriver preference adaptation
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The system continuously monitors the driver's start operation timing and uses this feedback to learn and adapt to individual preferences. By implementing a feedback loop that observes actual driver behavior and adjusts notification timing accordingly, the system maintains ease of operation while achieving high adaptability to individual drivers.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The notification device autonomously learns driver preferences through continuous observation of start operation patterns, eliminating the need for manual preference setting while still providing personalized notification timing. This self-learning capability resolves the contradiction between operational simplicity and preference adaptation.

Inventive Principle:
Principle #25Self-service

AI summary

The notification processing of the start operation delay of the vehicle by the driver is performed. In the notification processing, a timing for notifying the start operation delay is set using the first variable set using the passenger information, the second variable set using the driving environment information, and the third variable set using the learning value information. When the start operation by the driver is not detected until the timing of notifying the start operation delay elapses from the timing determined to permit the start of the vehicle, the notification device is activated.
