Driver Passenger HUD Control Transfer for Vehicle Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Safety regulations prohibit drivers from interacting with certain vehicle functions while driving, but passengers are not similarly restricted, limiting the driver's ability to manage vehicle functions during low speeds without risking distraction.
Innovation Solution
A system using a driver HUD and a passenger HUD, with a processor that enables control of vehicle functions via the driver HUD at low speeds and transitions control to the passenger HUD when the vehicle exceeds a speed threshold, allowing passengers to manage functions like route entry, communication, and entertainment systems while preventing driver distraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the driver HUD displays control options for vehicle functions, then the driver can easily control these functions, but the driver may be distracted from the road
Solution Approach 1:
The control system is segmented into two separate HUDs: a driver HUD and a passenger HUD. The driver HUD displays essential driving information and limited vehicle function controls (only when vehicle is stationary or moving very slowly), while the passenger HUD handles entertainment, communication, and other non-essential vehicle functions. This segmentation allows the driver to maintain focus on the road while passengers can interact with the vehicle's entertainment and communication systems without distracting the driver.
2Reliability
If the vehicle speed is monitored to control driver access, then safety regulations are complied with, but the system complexity increases
Solution Approach 1:
The vehicle's existing speed sensor and processor are utilized to determine vehicle speed and control access to the driver HUD. The processor already performs multiple functions including monitoring vehicle operations and managing display outputs. By leveraging these existing multi-functional components, the system achieves speed-based control compliance without adding significant complexity. The same processor that manages overall vehicle operations also handles the speed-threshold logic for HUD access control.
Data Source
AI summary
Method and apparatus are disclosed for transferring control of one or more vehicle functions from a driver HUD to a passenger HUD. An example vehicle includes a driver HUD, a passenger HUD, and a processor. The processor is configured for enabling control of one or more vehicle functions via the driver HUD responsive to determining that the vehicle speed is below a threshold. The processor is also configured for transitioning control of the one or more vehicle functions from the driver HUD to the passenger HUD responsive to determining that the vehicle speed has increased above the threshold.
