Vehicle Control Handoff to External Processors for OS-Driven Upgrades
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of updating hardware in vehicle devices to accommodate increased performance requirements due to frequent updates of general-purpose operating systems is difficult, especially since vehicles may not be easily upgraded every year or few years after shipment.
Innovation Solution
A vehicle device configuration that includes a control unit, connection portion, and determination unit to connect and utilize external devices with higher processing power, allowing activation and deactivation of functions based on the external device's operational state, thereby enhancing performance without excessive power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If hardware is upgraded to accommodate increased performance requirements from frequent OS updates, then processing performance is improved, but hardware complexity and upgrade difficulty increase
Solution Approach 1:
The system dynamically switches between internal control unit and external device based on operational needs. The determination unit assesses whether the external device is in an executable state and activates it when appropriate, allowing the system to adapt its processing architecture rather than being fixed
Solution Approach 2:
The control unit serves multiple functions: it processes vehicle operations independently, manages external device connections, determines executable states, activates external devices, and switches functions between internal and external processing. This multi-functional design reduces the need for dedicated hardware components
2Productivity
If external devices are activated to improve performance, then processing capability increases, but power consumption increases
Solution Approach 1:
The determination unit periodically checks whether the external device is in an executable state during vehicle operation. This periodic assessment allows the system to activate the external device only when needed rather than continuously, reducing unnecessary power consumption while maintaining processing capability when required
Solution Approach 2:
The system dynamically activates or deactivates the external device based on real-time conditions. The control unit monitors the executable state and switches between internal and external processing modes, optimizing power consumption according to actual performance needs
3Use of energy by moving object
If the control unit stops functions when external device executes them, then power consumption is reduced, but system reliability may decrease
Solution Approach 1:
The determination unit continuously monitors the external device's executable state and provides feedback to the control unit. This feedback mechanism ensures that functions are stopped only when the external device is confirmed to be executable, and restarted when it becomes unavailable, maintaining system reliability through continuous state verification
Solution Approach 2:
The system prepares for potential external device failures by having the control unit capable of resuming functions. When the determination unit detects that the external device is no longer in an executable state, the control unit automatically restarts the stopped functions, providing a safety net against reliability issues

AI summary
A vehicle device in one embodiment includes: a control unit accesses a peripheral device and executes functions when a vehicle is used; a connection portion to which an external device is connected, the external device communicable with the control unit and executing a function when the vehicle is used; and a determination unit determining whether the external device is connected to the connection portion in an executable state of the function. The control unit activates the external device to enable execution of the function and stops at least one function when the external device is determined to be connected to the connection portion in the executable state. The control unit executes the at least one function being stopped for the external device to execute the function when the external device is determined to be no longer in the executable state.
