Adaptive Driver Assistance System for Reducing Information Overload
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver assistance systems overwhelm drivers with unnecessary information, distracting them from the traffic situation, as they present fixed schemes of data without considering the driver's current needs or awareness, leading to potential increased risk during complex traffic scenarios.
Innovation Solution
A system that combines environmental sensing data with driver requests, determined through speech commands, gestures, and vehicle control operations, to provide tailored information relevant to the driver's needs, focusing on the traffic scene and applicable rules, thereby reducing information overload.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If driver assistance systems present fixed schemes of information based on environmental sensing, then the driver receives comprehensive traffic situation data, but the driver is overwhelmed with unnecessary information and distracted from the traffic situation
Solution Approach 1:
The system determines the driver's current awareness state by analyzing speech commands, gestures, and vehicle control operations, then uses this feedback to adaptively filter and select which environmental information to present to the driver, ensuring information is provided only when the driver needs it
Solution Approach 2:
The information presentation scheme transitions from a fixed, static approach to a dynamic, adaptive system that continuously adjusts the type and amount of information presented based on the driver's real-time awareness state and needs
2Loss of information
If the system analyzes driver awareness to provide tailored information, then the driver receives relevant information, but the determination of driver state takes additional time before warnings can be presented
Solution Approach 1:
The system continuously monitors and analyzes driver state parameters (speech patterns, gestures, control operations) in advance to predict when information will be needed, preparing and pre-processing relevant environmental data so that information can be presented immediately when the driver requests it
Solution Approach 2:
The driver actively requests information through speech commands and gestures, eliminating the need for the system to continuously analyze and predict driver needs, thereby reducing system processing time while maintaining information relevance
3Ease of operation
If the system presents information based on fixed rules without considering driver needs, then the system is simple to operate, but the driver receives repetitive warnings that do not match current traffic situations
Solution Approach 1:
The system uses feedback from driver speech commands, gestures, and vehicle control operations to dynamically adjust information presentation, ensuring that warnings and notifications are contextually appropriate and match the current traffic situation rather than following fixed rules

AI summary
The invention regards a method and a system for assisting a driver in driving a vehicle, as well as a vehicle with such system being mounted thereon. Information on an environment of a vehicle is obtained by sensing the environment. Furthermore, information on applicable traffic rules is obtained. A request from a driver is determined from sensing at least one of a driver's utterance, gestures, gaze and operation of vehicle control. The traffic scene as sensed is assessed on the basis of the environmental information, the applicable traffic rules and the determined driver request. Information as requested to be output is generated in response to the determined request of the driver. Finally the information in response to the request from the driver is output.
