Dynamic Route Guidance for Caravan Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems lack effective communication and route guidance for vehicles following a lead vehicle, leading to safety concerns and difficulties in maintaining coordination, especially in situations where followers may get separated or need to communicate during driving.
Innovation Solution
A route guidance system with a communication unit, navigation unit, and display unit that transmits and receives vehicle coordinates, allows for friendship requests, and provides 'Follow Me' or 'Lead Me' requests, using dedicated short-range communication to ensure safe and coordinated navigation between lead and follower vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a follower vehicle manually tracks a lead vehicle during caravaning, then the follower can maintain presence in the caravan, but the follower may get separated due to traffic lights, cutting off, or speed differences, leading to reckless driving or loss of contact
Solution Approach 1:
The system continuously receives location data from the lead vehicle and provides real-time feedback to the follower's navigation system, enabling automatic route adjustment to maintain caravan coordination without manual intervention
Solution Approach 2:
The follower's navigation system automatically recalculates and adjusts the route to track the lead vehicle's current location, making the system self-adjusting without requiring the follower driver to manually re-enter destinations or adjust navigation settings
2Loss of information
If the follower driver calls or texts the lead vehicle when separated, then communication can be restored, but this creates safety concerns during driving and requires manual intervention
Solution Approach 1:
The system provides continuous location feedback between vehicles through the navigation system, allowing drivers to monitor each other's position without manual communication, thus maintaining awareness without requiring phone calls or texts
Solution Approach 2:
The patent replaces manual communication methods (phone calls, texts) with an automated electronic communication system integrated into the navigation device, which continuously exchanges location data between vehicles
3Reliability
If the navigation system continuously updates route to track lead vehicle location, then caravan coordination is maintained, but this requires real-time data transmission and processing
Solution Approach 1:
The system uses the existing navigation device's route calculation and display capabilities for dual purposes: traditional destination navigation and dynamic caravan tracking, avoiding the need for separate dedicated tracking hardware
Solution Approach 2:
The navigation device acts as an intermediary that receives location data from the lead vehicle, processes it through existing route calculation algorithms, and presents it to the follower driver in the familiar map display interface

AI summary
A route guidance system for a navigation system includes a communication unit, a navigation unit, and a display unit. The communication unit transmits and receives vehicle coordinates from a remote lead vehicle. The navigation unit determines a route and provides directions for a user to the remote lead vehicle. The display unit displays a location of the user, the coordinates of the remote lead vehicle, the route from the user to the remote lead vehicle, and the directions.
