Driver Assistance Control Using Personalized Travel Envelopes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver assistance systems struggle with acceptance by drivers due to interventions that are not tailored to individual driving behaviors, leading to deactivation when interventions are perceived as disruptive.
Innovation Solution
A method and system that utilize driver-specific parameters to define a multidimensional boundary for vehicle guidance, predicting future trajectories, and intervening only when deviations occur outside this boundary, with interventions tailored to the driver's behavior and skills.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If multiple separate assistance systems (lane keeping, lane changing, collision warning) are implemented independently, then each system can be developed and maintained separately, but the overall system complexity increases and requires multiple software updates
Solution Approach 1:
The patent combines multiple independent assistance systems (lane keeping assistance, lane changing assistance, collision warning assistance) into a single integrated software module. This consolidation allows all assistance functions to be implemented through one unified codebase, eliminating the need for separate development, testing, and updating of individual systems while reducing overall system complexity.
2Reliability
If assistance systems are updated separately for different functions, then specific bugs can be fixed individually, but the number of required software updates increases and maintenance burden grows
Solution Approach 1:
By merging all assistance system functions into a single software update package, the patent enables simultaneous updating of lane keeping, lane changing, and collision warning functionalities. This approach reduces the frequency and time required for software updates while maintaining high reliability through comprehensive testing of the integrated system.
3Productivity
If different assistance systems use separate evaluation and planning modules, then each system can be optimized independently, but the overall processing time increases and system coordination becomes more difficult
Solution Approach 1:
The patent merges the evaluation and planning modules of different assistance systems into a unified modular architecture. This integration allows for optimized information sharing and coordinated decision-making across all assistance functions, reducing processing time and eliminating the need for complex inter-system coordination while maintaining the ability to optimize individual modules.

AI summary
The invention relates to a method for assisting a driver (60) of a vehicle (50) by means of at least one assistance system (1), wherein: driver-specific driving parameters (10) are obtained, a boundary travel envelope (20) is determined for an upcoming route section based on the driver-specific driving parameters (10), a future trajectory (21) of the driver (60) is predicted for the upcoming route section based on a current status (11) of the vehicle (50), a previous driving behaviour (12) of the driver (60) and the driver-specific driving parameters (12), and it is checked whether the future trajectory (21) lies within the determined boundary travel envelope (20), and an intervention of the assistance system (1) in a longitudinal and/or lateral control (52) of the vehicle (50) takes place if the predicted future trajectory (21) leaves the determined boundary travel envelope (20). The invention also relates to an assistance system (1).
