Autonomous Driving Time Estimation via Approved Road Characterization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current motor vehicle navigation systems with autonomous driving capabilities do not allow drivers to predict the operating time of a vehicle in autonomous mode along a route, making it difficult to plan activities during travel.
Innovation Solution
A device and method that estimate the operating time of a motor vehicle in autonomous mode by identifying and characterizing approved road portions, determining regulatory speeds, and considering traffic conditions, allowing for accurate calculation of eligible autonomous operation time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If autonomous driving system includes geolocation device and approved road identification, then autonomous operating mode availability is determined, but driver cannot predict operating time in autonomous mode
Solution Approach 1:
The system performs preliminary calculation of autonomous mode operating time before the driver needs to plan activities. The estimating device computes the duration of autonomous mode operation along the route in advance, providing this information to the driver before the journey begins or during route planning, enabling better activity scheduling and time management.
2Measurement precision
If system identifies and characterizes approved road portions, then accurate autonomous mode time estimation is achieved, but system complexity increases
Solution Approach 1:
The estimating device leverages existing multi-functional components of the autonomous driving system. It reuses the geolocation device for position determination, the approved road identification element for road classification, and the regulatory speed database for speed information. By making these existing components serve the additional function of time estimation through integration and data processing, the system achieves accurate estimation without proportionally increasing complexity.

AI summary
A method and device for estimating the operating time of a motor vehicle in autonomous mode for at least one route between a departure point and an arrival point. The estimating device is connected to an identifying element and to an element for characterizing portions of roads approved for the operation of the vehicle in autonomous mode, along the at least one route. The estimating device includes a unit for calculating the time during which the vehicle is eligible to operate in autonomous mode depending on the characterization of approved portions of road.
