Cornering-Adaptive Driver Assistance for Two-Wheeler Distance Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dynamic driver assistance systems in vehicles, particularly two-wheelers, often cause uncomfortable and unnecessary interventions during cornering due to reduced detection performance and misinterpretation of objects, distracting the driver and compromising safety.
Innovation Solution
A driver assistance system that dynamically adjusts its distance and attention functions based on vehicle tilt and cornering, attenuating interventions during turns to maintain driver focus and comfort, using sensors to monitor proximity and trigger low-threshold alerts when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the driver assistance system continuously monitors distance and triggers system interventions to maintain safety distance, then safety is improved, but driver comfort deteriorates due to unnecessary interventions during cornering
Solution Approach 1:
The driver assistance system dynamically adjusts its monitoring and intervention behavior based on vehicle operating conditions. During cornering (when lateral acceleration exceeds a threshold), the system reduces or suspends distance monitoring interventions. This dynamic adaptation allows the system to maintain safety during straight-line driving while avoiding unnecessary interventions that would discomfort the driver during cornering maneuvers.
2Reliability
If the driver assistance system triggers low-threshold system interventions to alert distracted drivers, then driver attention is improved, but driver comfort deteriorates due to noticeable jerks
Solution Approach 1:
The system dynamically adjusts the threshold for triggering attention-alerting interventions based on vehicle dynamics. During cornering, the system raises or disables the attention function threshold, preventing low-threshold interventions that would create noticeable jerks and discomfort. During straight-ahead driving, the system maintains sensitive low-threshold interventions to effectively alert distracted drivers, balancing attention enhancement with driver comfort.
3Reliability
If the driver assistance system maintains strict safety distance monitoring, then collision risk is reduced, but false alarms increase during cornering due to misinterpretation of objects
Solution Approach 1:
The distance monitoring function dynamically adjusts its sensitivity and activation status based on vehicle cornering status. During cornering maneuvers, the system suspends or attenuates distance monitoring to prevent false alarms caused by misinterpretation of objects in the periphery. During straight-line driving, the system maintains strict monitoring to effectively reduce collision risk, thereby eliminating false alarms while preserving safety functionality.

AI summary
A method for operating a vehicle with a driver assistance system. A distance function of the driver assistance system regulates a distance from a preceding target object using system interventions in a brake system and/or a drive system of the vehicle to a speed-dependent safety distance, wherein the distance function is degraded during cornering of the vehicle.
