Ground-Based Device Wireless Route Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for providing route data to motor vehicles are limited in that they cannot sense or provide information about areas outside their field of vision or sensing range, making it difficult for drivers or automatic guidance systems to navigate through unfamiliar or poorly visible areas such as narrow alleys or multistorey car parks.
Innovation Solution
A ground-based device with a transceiver and data memory is positioned along the route, transmitting route data wirelessly to vehicles, allowing for decentralized and flexible data provision, including information about route contours and obstacles, which can be updated based on sensor data and vehicle interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a motor vehicle uses its own sensors (cameras, ultrasonic sensors) to sense surroundings, then the vehicle can detect objects within its field of vision and sensing range, but route areas outside the field of vision or sensing range cannot be sensed
Solution Approach 1:
The patent introduces ground-based devices as intermediary elements that sense and store route data, then transmit this information to vehicles. These ground-based devices act as mediators between the environment and the vehicle, providing route information about areas outside the vehicle's direct sensing range without requiring the vehicle to have extended sensing capabilities
Solution Approach 2:
The ground-based devices perform preliminary sensing and storage of route data before vehicles arrive. The devices capture images and sensor data, store route contours and obstacle information in advance, making this information available to vehicles before they enter the areas, thus eliminating the need for vehicles to sense everything in real-time
2Loss of information
If complete road recordings are stored centrally at companies and made available via the Internet, then data is accessible, but the recorded images reflect random situations and are not necessarily suitable for assisting vehicle drivers
Solution Approach 1:
The system implements feedback mechanisms where ground-based devices continuously sense the current state of the route, compare it with stored reference data, and update the route data when changes are detected. This ensures the route information reflects the actual current situation rather than random or outdated conditions, improving reliability while maintaining accessibility
Solution Approach 2:
The route data system transitions from static, randomly captured images to dynamic, continuously updated information. Ground-based devices regularly sense the route and update stored data based on current conditions, making the system adaptive to changes in the environment while maintaining centralized accessibility
3Adaptability or versatility
If a control center collects information from vehicles and transmits it to other vehicles, then routing information can be provided, but the system requires centralized control infrastructure
Solution Approach 1:
The system segments the information gathering and transmission functions by placing sensing and storage capabilities directly at ground-based locations along the route. Each ground-based device operates independently to sense and store local route data, eliminating the need for a centralized control center while maintaining the ability to share information with multiple vehicles
Data Source
AI summary
Ground-based devices are provided which each have a transceiver apparatus and a data memory. Route data are stored in the data memory. This route data can be transmitted in a wireless fashion from the ground-based device to motor vehicles so that information relating to such a route is made available in the motor vehicles which are located outside the sensing range of a sensing apparatus of the motor vehicle.
