Side Mirror Angle Control for Detecting Merging Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional advanced driver assistance systems (ADAS) face difficulties in identifying vehicles merging from the side due to differences in heading direction, requiring manual adjustment of side mirrors or lowering windows, especially during turns.
Innovation Solution
A vehicle system utilizing V2X communication to control side mirrors based on data from sensors and communication with nearby vehicles and infrastructure, adjusting the mirror angles to include approaching vehicles in the driver's view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional ADAS uses rear camera to display rear image when driver inputs turn signal, then rear view is provided, but driver cannot acquire rear image without separately manipulating multi-function switch and cannot identify merging vehicles effectively
Solution Approach 1:
The system performs preliminary actions by automatically adjusting the side mirror angle before the driver needs to check for merging vehicles. The controller receives V2X communication data about nearby vehicles and proactively positions the side mirror to display the approaching vehicle, eliminating the need for manual mirror adjustment and ensuring the driver has the necessary visual information ready.
Solution Approach 2:
The side mirror system serves itself by automatically adjusting its own angle based on received communication data about nearby vehicles. The controller autonomously determines the appropriate mirror angle and actuates the mirror without requiring driver intervention, making the system self-regulating and responsive to environmental conditions.
2Loss of information
If driver manually adjusts side mirror or lowers window to check for approaching vehicles, then visibility of merging vehicles is improved, but driver convenience is reduced and additional manual operations are required
Solution Approach 1:
The side mirror system serves itself by automatically adjusting its own angle based on received communication data about nearby vehicles. The controller autonomously determines the appropriate mirror angle and actuates the mirror without requiring driver intervention, making the system self-regulating and responsive to environmental conditions.
Solution Approach 2:
The system uses feedback from V2X communication data about nearby vehicle positions and headings to automatically adjust the side mirror angle. The controller continuously receives updates about the environment and adjusts the mirror accordingly, creating a closed-loop system that responds to changing conditions without manual input.
3Device complexity
If side mirror angle is fixed, then device complexity is reduced, but ability to identify merging vehicles with different heading directions is compromised
Solution Approach 1:
The side mirror system transitions from a static, fixed-angle design to a dynamic, adjustable system. The mirror angle is no longer fixed but can be automatically adjusted based on real-time communication data about nearby vehicles. This dynamic capability allows the mirror to optimize its viewing angle for different merging scenarios while maintaining relatively simple control logic through automated angle selection.
Data Source
AI summary
An embodiment vehicle includes a sensor configured to acquire surrounding state data of the vehicle and internal state data of the vehicle, a communicator configured to communicate with a nearby vehicle, a side mirror having an angle that is adjustable, and a controller configured to identify whether an automatic mirror control of the vehicle is performable based on the surrounding state data, the internal state data, and a communication between the communicator and the nearby vehicle, in response to identifying that the automatic mirror control of the vehicle is performable, to identify that the nearby vehicle is expected to cross the vehicle based on the communication and to identify an angle between a heading direction of the nearby vehicle and a heading direction of the vehicle, and to control an angle of the side mirror based on the identified angle.
