Solution Overview

Problem

Existing vehicle shift control technologies require numerous shift patterns and are inefficient in preventing busy shift and acceleration delay phenomena due to their reliance on traditional shift patterns rather than predictive models.

Innovation Solution

A deep learning model-based system that predicts vehicle speed and accelerator position sensor values for each future time point, allowing for the prediction and control of gear stages to prevent busy shift and acceleration delay by maintaining or adjusting gear stages based on predicted conditions.

VSEngineering Contradiction Analysis

1Reliability

If traditional shift patterns are used to control vehicle shift, then the shift control logic becomes complex with hundreds of patterns required, but the system can prevent busy shift and acceleration delay phenomena

Engineering Contradiction:
Improveshift control stabilityVSAvoidshift control logic complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent transforms the complex shift control problem by changing the control parameters from discrete shift patterns to continuous prediction variables (vehicle speed, APS value, gear stage) with associated uncertainty levels. This allows the system to determine shift timing based on predicted values and uncertainty comparisons rather than consulting hundreds of predefined patterns, thereby reducing logical complexity while maintaining control reliability

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system performs preliminary prediction of future vehicle speed, APS value, and gear stage before actual shift execution. By predicting these parameters in advance and comparing uncertainty levels, the system proactively determines optimal shift timing and prevents busy shift phenomena before they occur, rather than reacting to current conditions with complex pattern matching

Inventive Principle:
Principle #10Preliminary action

2Device complexity

If deep learning model prediction is used to control shift, then the shift control logic complexity is reduced, but the ability to accurately predict future conditions and prevent busy shift and acceleration delay phenomena may be affected

Engineering Contradiction:

Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The system incorporates feedback mechanisms by comparing predicted values with actual sensor readings and calculating uncertainty levels. The uncertainty level serves as a feedback parameter that indicates prediction reliability, allowing the system to adjust control decisions based on the quality of predictions. This feedback loop ensures that the simplified prediction-based control logic maintains reliability by adapting to actual system behavior

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces the mechanical system of predefined shift patterns with an intelligent prediction system using deep learning models. Instead of mechanically selecting from hundreds of predefined patterns based on current conditions, the system uses neural network predictions of future states to determine shift timing, substituting complex mechanical logic with adaptive intelligent control that reduces logical complexity while maintaining or improving reliability

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
