GNSS-Based Racing Travel Time Measurement with Course Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for measuring travel time of racing vehicles in motorsports require permission or payment to use circuit-owned measurement systems, and aggregating travel times across different courses is meaningless without identifying the same course.
Innovation Solution
A travel time providing device that identifies racing courses based on vehicle position data, measures travel times, and stores them in a database for user access, allowing comparison of travel times on the same course.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a circuit-owned measurement system is used to measure travel time, then measurement accuracy is improved, but cost and operational complexity increase due to permission requirements and fees
Solution Approach 1:
The patent replaces the traditional mechanical/circuit-based measurement system with a GNSS-based system. Instead of using circuit-owned infrastructure (timing machines, sensors embedded in the track), the invention uses satellite-based positioning to measure travel time, thereby eliminating the need for permission and fees while maintaining measurement capability
Solution Approach 2:
The patent introduces GNSS (Global Navigation Satellite System) as an intermediary between the racing vehicle and the measurement system. The GNSS receiver in the vehicle uses satellite signals to determine position and calculate travel time, serving as a mediator that eliminates direct dependency on circuit infrastructure
2Quantity of substance
If travel times of multiple racing vehicles on multiple courses are aggregated on the server, then data aggregation capability is improved, but data relevance decreases because travel times on different courses cannot be meaningfully compared
Solution Approach 1:
The patent segments the aggregated travel time data by course identification. Instead of presenting a single mixed list of all travel times, the system divides the data into course-specific groups using course ID tags, allowing meaningful comparisons only within the same course while maintaining the ability to aggregate data from multiple courses
Solution Approach 2:
The patent applies local quality by tagging each travel time record with course-specific information (course ID, course name). This allows the system to treat different courses as distinct categories, preserving the relevance and comparability of data within each local course context while maintaining overall aggregation capability

AI summary
The course DB stores a plurality of combinations of the layout of a course and the measurement reference position of that course. The course identification unit refers to the course DB and identifies the course traveled by the racing vehicle based on the route traveled by the racing vehicle. The travel time measurement unit measures the travel time of the racing vehicle based on the measurement reference position of the identified course, the vehicle position information of the racing vehicle, and the vehicle position acquisition time associated with each vehicle position information, and stores the information indicating the course and the measured travel time in the travel time DB. The information indicating the course and the measured travel time are associated and stored in the travel time DB. The provision processing unit provides multiple travel times associated with the same course to the user.
