Follower Vehicle Navigation Path to a Real-Time Leader Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In group vehicle trips, drivers using individual navigation devices often cannot communicate safely and may lose sight of each other, leading to inconvenience and delayed assistance in case of accidents, as they need to coordinate routes and positions in real-time.
Innovation Solution
A navigation system where portable devices, connected to a cloud-based map-and-information system and vehicle instrument cluster devices, compute and display dynamic navigation paths from follower vehicles to a leader vehicle in real-time, allowing followers to reach the destination without setting their own routes and maintaining awareness of the leader's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If member drivers use individual navigation devices to acquire routes, then each driver can navigate independently, but they cannot communicate with each other in real-time and may lose sight of the group
Solution Approach 1:
The patent combines individual navigation devices with a group communication system. Each driver's portable device not only provides individual route navigation but also shares real-time position data with other group members through a server, merging independent navigation with group coordination capabilities.
Solution Approach 2:
The system implements real-time feedback by continuously transmitting and receiving position data between all group members' portable devices. Each driver receives updates on the real-time positions of other group members, enabling immediate awareness and coordination without requiring direct visual contact.
2Adaptability or versatility
If member drivers separate to follow individual routes, then each driver has route flexibility, but they cannot provide immediate assistance to each other in case of accidents
Solution Approach 1:
The system maintains reliability by implementing continuous real-time position feedback among all group members. Even when drivers follow different individual routes, the server continuously transmits position data, ensuring that any driver can immediately locate and assist others in case of emergencies.
Solution Approach 2:
The server acts as an intermediary that facilitates safety assistance capability. It collects position data from all portable devices and redistributes this information to all group members, enabling indirect awareness and coordination that maintains safety even when drivers are geographically separated.
3Reliability
If drivers cannot communicate by phone or social networking software for safety reasons, then communication safety is improved, but route coordination becomes difficult
Solution Approach 1:
The server serves as a safe intermediary for route coordination. It receives position data from all portable devices and automatically processes and distributes this information to all group members, eliminating the need for direct driver-to-driver communication while maintaining effective route coordination.
Solution Approach 2:
The system enables self-service route coordination where each driver's portable device automatically transmits their position data to the server and receives position data from other group members without requiring manual communication actions. The system performs the coordination function automatically, improving ease of operation while maintaining communication safety.

AI summary
A navigation method is implemented by a group of portable devices (6, 6a, 6b, 6c) which are associated with a map-and-information system (71) and each of which is communicatively coupled to an instrument cluster device (5, 5a, 5b, 5c) of a respective vehicle (1, 1a, 1b, 1c). The group of the portable devices (6, 6a, 6b, 6c) includes a leader device (6a) and at least one follower device (6b, 6c). The map-and-information system (71) computes, for the follower device (6b, 6c), a dynamic navigation path from the follower device (6b, 6c) to the leader device (6a). The instrument cluster device (5b, 5c) of the vehicle (1b, 1c) that corresponds to the follower device (6b, 6c) perceivably outputs the dynamic navigation path.
