Autonomous Driving Waypoint Action Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous driving systems lack the capability to perform appropriate actions at waypoint destinations, which are locations visited before reaching the final destination, requiring vehicles to take specific actions that differ from those at the final destination.
Innovation Solution
An autonomous driving system that includes a waypoint destination database to store data associating waypoint destinations with preset vehicle actions, an electronic control unit to present these actions to occupants and obtain permission, and perform the actions when permitted, such as hazard-light-on stops or parking, while managing restart conditions and hazard light timing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the autonomous driving system performs basic navigation to destination, then the driving function is simple and reliable, but the system cannot perform appropriate actions at waypoint destinations
Solution Approach 1:
The system performs preliminary actions by pre-storing action information in the database before reaching waypoint destinations. The ECU retrieves and executes appropriate actions (such as hazard light activation, parking) based on pre-defined waypoint types, enabling the vehicle to autonomously perform correct actions without real-time complex decision-making
Solution Approach 2:
The patent introduces an intermediary database that stores the mapping relationship between waypoint destination types and corresponding vehicle actions. This database acts as a mediator between the navigation system and vehicle control systems, translating waypoint information into specific executable actions without requiring complex real-time processing
2Productivity
If the system automatically performs actions at waypoint destinations, then operational efficiency is improved, but occupant control and permission are reduced
Solution Approach 1:
The system implements feedback by notifying the occupant of upcoming waypoint destinations and their associated actions through the notification device. The occupant can provide feedback by inputting permission or modification requests, which the ECU processes to adjust or cancel actions accordingly, ensuring human oversight while maintaining operational efficiency

AI summary
An autonomous driving system includes a waypoint destination database storing waypoint destination data associating a type of a waypoint destination with a preset action of a vehicle. The waypoint destination is a destination that the vehicle visits before arriving at a predetermined destination. The autonomous driving system includes an electronic control unit. The electronic control unit is configured to autonomously drive the vehicle toward the predetermined destination, set the waypoint destination, present the preset action performed at the waypoint destination, to an occupant of the vehicle, based on the waypoint destination and the waypoint destination data. The electronic control unit is configured to determine whether the preset action is permitted by the occupant, and cause the autonomously driven vehicle to perform the preset action at the waypoint destination when it is determined that the preset action is permitted by the occupant.
