Vehicle Safety Check System for High-Performance Feature Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-performance vehicle features like line lock and drift mode are often engaged accidentally or inappropriately outside of racetracks, without warnings regarding the vehicle's location or surroundings, posing safety risks.
Innovation Solution
A system utilizing a GPS receiver, sensors, and a processor to determine road type, clearance status, and weather conditions, generating warning messages with an override button to prevent engagement of high-performance features in unsuitable conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If high-performance vehicle features are engaged without safety checks, then ease of operation is improved, but safety and reliability deteriorate
Solution Approach 1:
The system performs preliminary safety checks by determining road type using GPS location information and assessing road clearance status using sensor data before allowing engagement of high-performance vehicle features. This preliminary action prevents unsafe operation by evaluating environmental conditions in advance.
Solution Approach 2:
The system provides feedback to the driver through warning messages that display the detected road type and clearance status, informing the driver whether current conditions are suitable for high-performance features. This feedback loop enables the driver to make informed decisions about feature engagement.
2Reliability
If safety checks are implemented before feature engagement, then reliability is improved, but device complexity increases
Solution Approach 1:
The processor performs multiple functions using existing vehicle systems: it determines road type using GPS receiver data, assesses road clearance using sensor information, generates warning messages, and controls feature engagement. This multi-functionality approach avoids adding separate dedicated systems for each safety check function.
Solution Approach 2:
The system uses the existing GPS receiver and sensor networks as intermediaries to gather environmental information, rather than requiring new dedicated detection devices. These existing components mediate between the environment and the safety control system.
3Reliability
If the system provides detailed warnings about road conditions, then safety is improved, but loss of time increases due to driver attention requirements
Solution Approach 1:
The system provides partial information by displaying only the critical road type and clearance status that are most relevant to safety decisions. This selective information provision avoids overwhelming the driver with excessive details while still conveying essential safety warnings.
Solution Approach 2:
The system performs the time-consuming analysis of road type and clearance status in advance, before the driver needs to make a decision. This preliminary processing reduces the time the driver must spend actively evaluating conditions at the moment of feature engagement.

AI summary
Methods and apparatus are disclosed to facilitate safety checks for high-performance vehicle features. An example vehicle comprises a global positioning system (GPS) receiver, sensors, a processor and a memory. The GPS receiver generates location information. The sensors generate road information. The processor and memory are in communication with the sensors and the GPS receiver. The processor is configured to: determine a road type using the location information; determine a road clearance status using the road information; and generate a warning message including an override button based on one or more of the road type and the road clearance status.
