Driver Assistance Selection Using a Vehicle Surroundings Model
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current driver assistance systems in vehicles are often not used in their specified useful areas, leading to incorrect behavior, such as using adaptive cruise control in city traffic, due to driver unfamiliarity or inhibitions about activating these systems.
Innovation Solution
A method that utilizes a vehicle surroundings model to determine situation-specifically suitable driver assistance systems by analyzing surroundings data, which are then proposed to the driver through a display device, optionally using an animated avatar for better understanding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If driver assistance systems are manually activated by drivers, then drivers have control over system usage, but drivers often use systems incorrectly or in inappropriate situations due to unfamiliarity
Solution Approach 1:
The system automatically determines and activates appropriate driver assistance systems based on the vehicle surroundings model and current travel situation, without requiring manual driver activation. The system serves itself by autonomously selecting and executing the suitable assistance system, eliminating the need for driver knowledge about system activation.
Solution Approach 2:
The system continuously receives feedback from sensors and the vehicle surroundings model about the current travel situation, and uses this feedback to dynamically select and activate the most appropriate driver assistance system. This closed-loop feedback mechanism ensures the system adapts to changing conditions and maintains correct usage.
2Adaptability or versatility
If drivers are provided with more information about driver assistance systems, then driver familiarity improves, but system complexity and information processing requirements increase
Solution Approach 1:
The vehicle surroundings model acts as an intermediary that automatically processes and interprets complex sensor data, travel situation information, and driver assistance system characteristics. This intermediary layer handles the complexity of information processing, presenting only the necessary activation decisions to the execution layer without burdening the driver with system complexity.
3Reliability
If driver assistance systems are automatically activated based on travel situation, then correct usage in appropriate areas improves, but system complexity and automation level increase
Solution Approach 1:
The system pre-establishes a vehicle surroundings model that contains predetermined characteristics and suitability criteria for different driver assistance systems before actual activation is needed. This preliminary preparation of the model and criteria allows the system to quickly and reliably determine appropriate activation without complex real-time decision-making, reducing the perceived complexity during operation.

AI summary
A driver assistance method by a control device of a motor vehicle includes receiving surroundings data, which describe a current travel situation in a region around the motor vehicle; on basis of the received surroundings data, providing a vehicle surroundings model, which describes the current travel situation and surroundings of the motor vehicle; checking whether one of a plurality of driver assistance systems available to the motor vehicle meets an assistance criterion which specifies a minimum probability with which a driver assistance system will assist the driver in the current travel situation and in the surroundings of the motor vehicle. If a driver assistance system that meets the assistance criterion is available, the control device is configured to generate an information display signal, which describes a digital representation of a proposal to use the driver assistance system that meets the assistance criterion; and transmits the generated information display signal to the display device. The digital representation can be an avatar.
