Lane Change Intention Recognition With AR Driver Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for recognizing a driver's intention in autonomous vehicles lack efficient processing and visualization of lane change commands, particularly in partially autonomous driving modes, which can compromise safety and convenience.
Innovation Solution
A device comprising an input interface for receiving sensor and control data, an analysis circuit to determine traffic situations, and an output interface for transmitting control commands to a vehicle unit, utilizing augmented reality displays to visualize control procedures, allowing drivers to input commands intuitively through conventional controls like the steering wheel and turn signal lever, even in autonomous modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional control inputs are used in autonomous driving mode, then ease of operation is improved, but reliability deteriorates due to potential misinterpretation of driver intent
Solution Approach 1:
The system displays a visual representation of the recognized driver intention on the head-up display, providing feedback to the driver about what the system has understood. This allows the driver to verify correct recognition and correct misinterpretations, thereby maintaining ease of operation while improving reliability through verification
Solution Approach 2:
The head-up display acts as an intermediary between the driver's control inputs and the vehicle's autonomous driving system. It translates and communicates the recognized intention visually, serving as a mediator that reduces misinterpretation while keeping the interface simple
2Reliability
If additional displays are added for visualization, then reliability is improved through better information presentation, but device complexity increases
Solution Approach 1:
The head-up display, already present in the vehicle for other purposes, is utilized to display driver intention recognition information. This multi-functional use of an existing component improves information presentation without adding new display hardware, thereby avoiding increased device complexity
Solution Approach 2:
The existing head-up display infrastructure serves the additional function of displaying driver intention, allowing the system to provide enhanced information presentation using already-deployed resources rather than requiring new display systems

AI summary
The disclosure relates to a device for recognizing an intention of a driver for a lane change assistant in an at least partially autonomous motor vehicle, a corresponding system, and a method and computer program. It is provided that steering of a driver does not directly cause lateral acceleration, as is currently the case, but rather serves the vehicle as an input medium for the intention of the driver to imminently initiate lateral acceleration, for example a turn-off procedure or a change of travel lane. As a result of the signal from the control element, a safe, drivable trajectory that will subsequently be traveled automatically by the vehicle is calculated. This may also include more complex driving maneuvers, such as a change of multiple travel lanes. As a result, driving is made more convenient and safer.
