Vehicle Navigation Waypoint Display with Traffic-Aware Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automotive navigation systems fail to effectively correlate waypoint information along a route with the time of arrival, which varies due to traffic flow conditions, and do not provide targeted advertising to vehicle occupants.
Innovation Solution
A navigation system that allows users to input desired waypoints and times, updates waypoint information based on traffic conditions, and displays only relevant information at the desired time, using a GPS receiver, map database, and two-way communication with content providers, while also filtering advertising based on occupant data and vehicle context.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If waypoint information is displayed along the route, then the quantity of information is improved, but screen clutter increases and readability deteriorates
Solution Approach 1:
The system pre-calculates and stores multiple alternate routes with their respective travel times before the user needs them. When a user specifies a desired arrival time, the system can immediately present pre-computed route options that match the time constraint, avoiding the need to display excessive real-time calculations or require repeated computations.
Solution Approach 2:
The system selectively displays waypoint information based on the specific route and time parameters chosen by the user. Rather than displaying all possible waypoints uniformly, it tailors the displayed information to the local context of the selected route and desired arrival time, showing only relevant waypoints that will actually be encountered on that specific path.
2Adaptability or versatility
If multiple route options are provided, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The system computes and stores a limited set of alternate routes that are sufficient to cover most user needs, rather than calculating all mathematically possible routes. This partial action approach provides adequate adaptability for typical driving scenarios while keeping the computational complexity and data storage requirements manageable.
Solution Approach 2:
The system pre-calculates and stores multiple alternate routes with their respective travel times before the user needs them. This preliminary computation allows the system to quickly present route options when a user specifies a desired arrival time, without requiring complex real-time calculations or iterative computations during user interaction.
3Reliability
If waypoint information is updated based on traffic conditions, then the reliability is improved, but the loss of time for updates increases
Solution Approach 1:
The system implements periodic updates of traffic conditions and waypoint information at predetermined intervals rather than continuous real-time updates. This periodic action maintains reliable information accuracy by regularly refreshing data while limiting the time and computational resources dedicated to updates, preventing excessive time loss.
Solution Approach 2:
The system incorporates feedback mechanisms that monitor changes in traffic conditions and only trigger waypoint information updates when significant changes are detected. This feedback-driven approach maintains high reliability by updating information when necessary while avoiding unnecessary updates that would waste time and computational resources.
Data Source
AI summary
A method for displaying waypoint information on the screen of a vehicle navigation system. The method includes the steps of displaying a route on the screen and inputting criteria which identify desired waypoints along the route as well as the desired time to reach the waypoint. The location of the desired waypoint along the route as a function of the desired time to reach the waypoint in traffic conditions is determined and that waypoint information is displayed on the screen. The method optionally utilizes two-way communication between the navigation system and waypoint content providers.
