Autonomous Vehicle Navigation with Stepwise User Route Commands
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current autonomous driving systems lack intuitive navigation methods for users to easily change routes, especially for detours, and require gadget-dependent check-in processes, which can be inconvenient for users without electronic devices.
Innovation Solution
A system that allows users to submit intuitive navigational commands (such as forward, turn left, turn right, and U-turn) to change travel routes and provides multiple check-in options, including QR-code printouts and simple numerical codes, enabling gadget-free interactions with autonomous vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users submit detailed destination information to change travel routes, then the routing accuracy is improved, but the ease of operation deteriorates because users need to manually input complex route details
Solution Approach 1:
The navigation command is segmented into simple directional components (forward, backward, turn left, turn right, U-turn) rather than requiring complete route description. Each button press represents a discrete navigation action that the system executes sequentially, breaking down complex routing into manageable steps that are easy for users to understand and input.
Solution Approach 2:
The system automatically calculates the complete travel route based on simple user commands without requiring users to manually input detailed destination information. When a user presses a directional button, the system independently determines the optimal path, calculates waypoints, and plans the entire journey autonomously, transforming minimal user input into comprehensive navigation instructions.
2Productivity
If the system requires electronic gadgets for check-in process, then the check-in efficiency is improved through automated verification, but the adaptability deteriorates for users without electronic devices
Solution Approach 1:
The check-in system supports multiple verification methods to serve diverse user needs. It can verify users through electronic gadgets (smartphone QR codes, RFID cards) for automated efficient check-in, or through traditional methods (manual ID verification, cash payment) for users without electronic devices. This multi-functional approach ensures the system adapts to different user scenarios while maintaining operational efficiency.
Solution Approach 2:
The system introduces an intermediary verification layer that can handle both electronic and non-electronic identification methods. Instead of directly requiring electronic gadgets, the system accepts various forms of identification (electronic QR codes, physical ID cards, manual verification) as intermediaries to confirm user identity and authorization, then processes the check-in uniformly regardless of the verification method used.
3Extent of automation
If the system provides only destination-based navigation, then the automation level is improved, but the ease of operation deteriorates when users need to take detours or make intermediate stops
Solution Approach 1:
The navigation system dynamically adjusts between two operational modes: fully automated destination-based navigation and interactive step-by-step guidance. When users need detours or intermediate stops, the system transitions to a more interactive mode where users can press directional buttons to modify the route in real-time. This dynamic adaptability allows the system to maintain high automation for straightforward journeys while becoming more user-controllable when detours are needed.
Solution Approach 2:
Instead of requiring users to specify the complete modified route when taking detours, the system accepts partial navigation instructions (individual directional commands) and automatically completes the remaining route planning. Users only need to indicate their desired deviation through simple button presses, and the system excessively generates the full set of navigation instructions including waypoints and turn-by-turn directions, reducing user burden while maintaining route accuracy.

AI summary
System and method for a user to navigate an autonomous vehicle. In an aspect, an identification object is presented at a vehicle hailed by a user. In another aspect, after a user submits a forward command, the vehicle is arranged to go straight within a given distance. In another aspect, after a user submits a turn-right command, the vehicle is arranged to turn right and then go straight within a given distance.
