Vehicle Speed Data Processing Device for Optimal Travel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for semi-autonomous or autonomous vehicle longitudinal guidance lack the ability to determine a comfortable and safe vehicle speed for a route section, particularly in dynamic conditions such as traffic jams or changing weather, and are influenced by slow-moving traffic.
Innovation Solution
A data processing device with a receiving and determining device, utilizing position determination systems like GPS, radar, and camera systems to assess the road conditions ahead, determines an optimal speed based on free travel information, adjusting for obstacles and stored data to ensure safety and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the optimal speed is determined based on all recorded driving speeds, then more data is available for calculation, but the optimal speed is falsified by slow-moving traffic such as traffic jams
Solution Approach 1:
The patent extracts and separates relevant data from the complete dataset by identifying and excluding driving speed records that do not meet the free travel criteria. Only driving speeds associated with free route sections are used for optimal speed calculation, thereby preventing traffic jam data from falsifying the results while maintaining sufficient data quantity for accurate determination.
2Productivity
If the vehicle is guided at maximum speed, then travel time is reduced, but safety reserves are insufficient for changed weather conditions or evasive maneuvers
Solution Approach 1:
The patent determines an optimal speed that is lower than the maximum possible speed, establishing a speed parameter that balances travel efficiency with safety requirements. This optimal speed provides sufficient safety reserves for weather changes and evasive maneuvers while maintaining acceptable travel productivity.
3Device complexity
If the optimal speed is determined without filtering traffic conditions, then the calculation is simpler, but the speed is falsified by slow-moving traffic
Solution Approach 1:
The patent performs preliminary filtering of driving speed data based on free travel information before calculating the optimal speed. By pre-screening and selecting only relevant data points associated with free route sections, the system maintains relatively simple processing while ensuring accurate optimal speed determination不受 traffic jam interference.
