Vehicle Control Unit for Intention-Based Function Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As vehicles become increasingly equipped with advanced functions, the need for users to manually operate pedals to determine intentions for braking, acceleration, or deceleration decreases operability, making it harder for users to benefit from these features.
Innovation Solution
A vehicle control unit with a memory section, user condition determination, intention determination, function control, and function selection sections that can assume user intentions based on detected movements and conditions without requiring direct pedal operation, allowing for the control of various vehicle functions and onboard devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If user detection device and intention determination are implemented, then user convenience and automated control are improved, but device complexity increases
Solution Approach 1:
The vehicle control unit is divided into distinct functional sections: user detection device, movement/condition determination section, intention determination section, function selection section, and function control section. This segmentation allows each component to perform a specific task, making the overall complex system more manageable and maintainable while providing automated control based on user state.
2Productivity
If multiple functions are controlled automatically, then productivity and vehicle control capability are improved, but ease of operation deteriorates due to reduced user control
Solution Approach 1:
The system continuously monitors user movement and condition through the user detection device, feeds this information to the movement/condition determination section, which then informs the intention determination section. This feedback loop allows the system to adaptively control vehicle functions based on real-time user state, improving control capability while maintaining appropriate user involvement.

AI summary
A vehicle control system has a detection section, a vehicle control unit, and a function section. The vehicle control unit has a memory section, a user condition determination section, a intention determination section, a function selection section, and a function control section. The user condition determination section determines movements and conditions of a user based on outputs of the detection section. The intention determination section determines intentions of the user based on results of the user condition determination performed by the user condition determination section and intention map data read from the memory section. The function selection section selects a function from a function section that includes multiple functions based on a result of the intention determination.
