Vehicle Occupant Request Control With Driver Approval Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle operations requested by non-driver occupants can increase the risk of distracting the driver or expose occupants to inappropriate content, and existing systems either implement these requests immediately, increasing distraction, or prohibit all non-driver access, leading to dissatisfaction.
Innovation Solution
A system and method in a vehicle that detects inputs from non-driver occupants, determines if the action is improper, notifies the driver, and executes the action only after receiving driver approval, allowing pre-authorized actions without driver intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the system executes requests from non-driver occupants immediately, then non-driver access to vehicle systems is maintained, but driver distraction risk increases
Solution Approach 1:
The system introduces an intermediary approval mechanism where driver authorization is required before executing non-driver requests. This mediator layer filters harmful actions while permitting beneficial ones, resolving the contradiction by allowing non-driver access under controlled conditions rather than immediate execution or complete prohibition
Solution Approach 2:
The system dynamically changes the execution parameter of non-driver requests based on safety assessment. Requests are categorized into different execution states (immediate execution, driver approval required, or prohibition) based on their potential to cause driver distraction, thereby adapting the system response to the specific request characteristics
2Object-affected harmful factors
If the system prohibits all non-driver access to vehicle systems, then driver distraction risk is reduced, but non-driver satisfaction decreases
Solution Approach 1:
The system applies different quality levels of access control to different types of requests. Rather than uniform prohibition, the system evaluates each request locally and applies appropriate restrictions or permissions based on its safety characteristics, maintaining satisfaction for safe requests while blocking harmful ones
Solution Approach 2:
The access control system transitions from a static all-or-nothing approach to a dynamic evaluation process. The system continuously assesses incoming requests against safety criteria and adjusts access permissions in real-time, enabling flexible control that maintains driver safety while accommodating non-driver needs
3Object-affected harmful factors
If the system evaluates each request for impropriety, then driver distraction risk is reduced, but system complexity increases
Solution Approach 1:
The system implements partial evaluation by focusing assessment on specific safety-critical parameters rather than comprehensive analysis of all request attributes. This selective evaluation approach reduces computational complexity while maintaining effective safety filtering for the most important risk factors

AI summary
A vehicle includes a non-transitory computer readable medium configured to store instructions thereon. The vehicle further includes a processor connected to the non-transitory computer readable medium. The processor is configured to execute the instructions for detecting an input from a non-driver occupant of the vehicle. The processor is configured to execute the instructions for determining whether the input is a request for an improper action. The processor is configured to execute the instructions for notifying the driver of the request in response to a determination that the input is the request for an improper action. The processor is configured to execute the instructions for executing the improper action in response to receiving approval from the driver following the notifying of the driver.
