Vehicle Media Playback Control Using Autonomous Driving Time Windows
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous driving systems restrict multimedia usage during vehicle travel, limiting convenience functions like video playback, despite the potential for autonomous driving to provide dedicated time for such activities.
Innovation Solution
A device and method that determine available autonomous driving time along a travel route, allowing multimedia playback and recommending content completion within that time, pausing and resuming playback based on driving mode changes, and providing this information to users through vehicle displays or terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If autonomous driving system is implemented, then convenience functions like multimedia playback can be used during vehicle travel, but safety regulations prohibiting video display during vehicle movement are violated
Solution Approach 1:
The system dynamically adjusts multimedia playback permissions based on the autonomous driving state. When the vehicle is in autonomous driving mode, video playback is permitted; when manual driving is detected, playback is automatically blocked. This dynamic state-dependent control resolves the contradiction by making multimedia convenience conditional on safety-critical driving modes.
Solution Approach 2:
The system changes the operational parameter of video display from a static prohibition to a dynamic permission based on driving mode detection. By monitoring driving state parameters (autonomous vs. manual control), the system selectively enables or disables multimedia functions, thereby maintaining safety compliance while enabling convenience when appropriate.
2Ease of operation
If multimedia playback is allowed during autonomous driving, then user convenience is improved, but inability to respond to autonomous driving termination events reduces safety
Solution Approach 1:
The system implements immediate feedback when autonomous driving terminates. Upon detecting termination of autonomous driving mode during multimedia playback, the system automatically pauses the playback and provides visual and/or audio notifications to alert the user. This feedback mechanism ensures users remain aware of critical driving state changes while still enjoying multimedia convenience during autonomous operation.
Solution Approach 2:
The system takes preliminary action by automatically pausing multimedia playback before the user needs to respond to autonomous driving termination. By proactively pausing playback and issuing alerts when termination is detected, the system prepares the user for potential manual intervention needs, maintaining safety awareness without compromising multimedia convenience during normal autonomous operation.
3Ease of operation
If content playback time exceeds available autonomous driving time, then user cannot complete content within the autonomous driving window, but restricting content selection reduces user freedom
Solution Approach 1:
The system provides feedback to users about the relationship between content duration and available autonomous driving time. Before allowing playback initiation, the system compares content length with the predicted autonomous driving window and notifies users if completion is not feasible. This feedback enables informed content selection without artificially restricting user freedom, allowing users to make decisions based on time availability.
Solution Approach 2:
The system allows users to initiate content playback even when full completion within the autonomous driving window is not guaranteed. Instead of completely blocking playback of longer content, the system permits partial playback during autonomous driving, automatically pausing when the window ends. This partial action approach maintains user freedom while managing time constraints realistically.
Data Source
AI summary
The present disclosure relates to a device and a method for controlling a vehicle. The device includes memory that stores program instructions, and a processor that executes the program instructions. The processor outputs, via a display of the vehicle and/or an audio system of the vehicle, an available autonomous driving travel time associated with a portion, of a travel route to a destination, that is suitable for autonomous driving. The available autonomous driving travel time is determined based on a location of the vehicle. Based on a determination that autonomous driving is activated for the vehicle, the processor allows media playback of in the vehicle.
