Automated Vehicle Fore Zone Indication for Dynamic Entry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional greeting scenarios for automated vehicles are less convenient for potential users in dynamic situations compared to stationary scenarios, as they fail to effectively indicate the target vehicle opening fore zone before the vehicle comes to a stop, especially in automated driving contexts where the vehicle is moving independently towards the user.
Innovation Solution
A method and control apparatus that identify the potential future vehicle user outside the vehicle using sensors and electronic appliances, and indicate the target vehicle opening fore zone optically or through augmented reality before the vehicle reaches a stopping position, adapting the display based on user movement and preferences, using lighting elements or projectors to guide the user to the appropriate entry or loading region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional greeting scenarios are used for automated vehicles, then the vehicle can activate lighting elements to greet the driver, but the potential vehicle user receives less convenience in dynamic situations where the vehicle moves independently toward the user
Solution Approach 1:
The patent applies dynamics by making the greeting scenario adaptive to the vehicle's motion state. The control apparatus determines whether the vehicle is stationary or moving, and adjusts the greeting behavior accordingly. When moving, the system dynamically updates the target vehicle opening fore zone indication to account for the vehicle's trajectory and stopping position, transforming a static greeting protocol into a dynamic one that responds to real-time motion conditions.
Solution Approach 2:
The patent applies preliminary action by indicating the target vehicle opening fore zone to the potential vehicle user before the vehicle reaches its stopping position. The control apparatus calculates the future stopping position based on current motion state and提前 (in advance) displays the greeting light pattern at the appropriate location, allowing the user to prepare for the vehicle's arrival and know where to approach for entry.
2Loss of information
If the vehicle activates lighting elements in conventional greeting scenarios, then the driver is greeted, but the target vehicle opening fore zone is not clearly indicated for moving vehicles
Solution Approach 1:
The patent applies the intermediary principle by using the greeting light pattern as a mediator to convey information about the target vehicle opening fore zone. The control apparatus modulates the greeting lights to not only greet the user but also to indicate the specific area where the vehicle opening will be located. This dual-function light signal serves as an intermediary that bridges the gap between the vehicle's motion state and the user's understanding of where to approach for entry.
3Extent of automation
If the vehicle moves independently toward the user, then automated driving functionality is achieved, but the greeting scenario becomes less convenient compared to stationary situations
Solution Approach 1:
The patent applies feedback by continuously monitoring the vehicle's motion state and using this information to adjust the greeting scenario. The control apparatus receives feedback about whether the vehicle is stationary or moving, and based on this feedback, it adapts the target vehicle opening fore zone indication. This closed-loop approach ensures that the greeting convenience is maintained even in automated driving situations by dynamically adjusting the light pattern indication based on real-time motion feedback.
