Adapting Driver Support Safety Thresholds by Driving Zone
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver support systems in vehicles do not effectively tailor safety margin thresholds to specific driving zones, leading to suboptimal safety and convenience for vehicle occupants.
Innovation Solution
A driver support threshold adapting system that determines the geographical position of a vehicle, selects a relevant driving zone, derives statistical driving behavior data, and adjusts safety margin thresholds for driver support functions based on historical safety indicators such as acceleration, speed, distance, and lane keeping, to enhance safety and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If driver support functions use fixed safety margin thresholds, then system simplicity is maintained, but safety and convenience are suboptimal for specific driving zones
Solution Approach 1:
The patent implements dynamic adjustment of safety margin thresholds based on geographical position and historical driving data. The system transitions from fixed thresholds to dynamically adaptable thresholds that change according to the vehicle's location and zone characteristics, resolving the contradiction between safety and system complexity
Solution Approach 2:
The system changes the parameter of safety margin thresholds from constant values to variable values that depend on geographical position and statistical driving behavior data. This parameter transformation enables the system to adapt safety levels to different driving zones while maintaining a manageable complexity through automated data processing
2Adaptability or versatility
If driver support functions are tailored to specific driving zones, then safety and convenience are improved, but system complexity increases
Solution Approach 1:
The patent divides the driving environment into distinct geographical zones with unique safety characteristics. By segmenting the operational space into manageable zones with pre-collected statistical data, the system achieves high adaptability to different driving conditions while keeping the complexity of individual zone management relatively low
Solution Approach 2:
The system performs preliminary actions by pre-collecting and storing statistical driving behavior data for various geographical zones before the vehicle actually enters them. This advance preparation enables rapid adaptation when the vehicle reaches each zone without requiring complex real-time analysis, thus improving adaptability while controlling system complexity

AI summary
The present disclosure relates to a method performed by a driver support threshold adapting system (1) for adjusting a safety margin threshold of one or more driver support functions (23) of a vehicle (2), to be suitable for a driving zone (4) in which the vehicle is - or is to be - positioned. The driver support threshold adapting system determines (1001) a geographical position (421) of the vehicle. The driver support threshold adapting system moreover determines (1002) a driving zone associated with the vehicle position, which driving zone is selected from one or more pre-defined geographical driving zones (5). Furthermore, the driver support threshold adapting system derives (1003) previous statistical driving behaviour data (8) indicative of one or more statistical driving style safety indicators (81) associated with the driving zone, and then adjusts (1004) a safety margin threshold of at least a first driver support function of the vehicle, based on the one or more statistical driving style safety indicators. The disclosure also relates to a driver support threshold adapting system in accordance with the foregoing, and a vehicle at least partly comprising such a driver support threshold adapting system.
