Vehicle Startability Prediction Using Future Weather Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver assistance systems for commercial vehicles only consider current battery parameters and ambient temperature, failing to provide reliable startability assessments for future start times and locations, which limits proactive measures to ensure vehicle startability.
Innovation Solution
A method using a measuring and control device that accounts for local temperature at a probable future vehicle start location, integrating weather data, route planning, and battery parameters to determine startability, allowing for early initiation of charging or energy-saving measures to ensure vehicle readiness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If only current battery parameters and ambient temperature are considered, then the assessment is simple and quick, but the startability prediction for future times and locations is unreliable
Solution Approach 1:
The system performs preliminary assessment of startability by integrating weather forecast data for future time points and locations into the evaluation. The measuring and control device retrieves predicted weather data and uses it to project battery temperature and startability at future moments, enabling proactive measures before actual start attempts.
Solution Approach 2:
A prognosis device acts as an intermediary between current battery measurements and future startability predictions. This intermediary component processes weather forecast data and current battery parameters to generate projected startability assessments, bridging the gap between present conditions and future outcomes.
2Loss of time
If startability is assessed only at current time, then the system is simple to operate, but proactive measures cannot be initiated in time
Solution Approach 1:
The system enables preliminary action by assessing startability at future time points using weather forecast data. This allows drivers to take preventive measures such as charging the battery or adjusting driving behavior before the actual start attempt, rather than reacting after problems occur.
Solution Approach 2:
The system provides feedback about future startability predictions to the driver, enabling informed decision-making. The measuring and control device communicates projected startability status and recommended actions, creating a feedback loop that guides preventive measures.
3Measurement precision
If weather forecast data for future locations is integrated, then future startability can be predicted accurately, but data processing requirements increase
Solution Approach 1:
The prognosis device serves as an intermediary that handles the complex task of integrating weather forecast data with battery parameters. It processes temperature predictions for future locations and times, translating raw weather data into meaningful startability assessments without burdening the overall system architecture.
