Vehicle Control Device Mode Switching for Lane Change Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automated driving systems cannot perform appropriate driving for each occupant, as they lack the ability to differentiate and adapt to individual preferences regarding lane changes.
Innovation Solution
A vehicle control device and method that includes user-operable inputs to switch between driving modes, allowing or prohibiting lane changes based on user input and situational determinations, enabling personalized automated driving experiences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If automated driving system determines default lane and automatically changes lanes, then lane change automation is improved, but user preference adaptation deteriorates
Solution Approach 1:
The system dynamically adjusts the degree of automation based on user preferences. Two driving modes are implemented: first mode where path change is prohibited and second mode where path change is allowed. The mode controller switches between these modes based on user input, making the automation level dynamic rather than fixed, thus resolving the contradiction between automation and adaptability.
2Ease of operation
If driving mode switches between first mode and second mode, then user control flexibility is improved, but system complexity deteriorates
Solution Approach 1:
The driving control system is segmented into distinct modes (first mode and second mode) with clearly defined characteristics. Each mode has specific rules about path change permission. This segmentation simplifies user interaction by providing discrete, understandable options rather than continuous adjustment, while the mode controller manages the complexity of switching between these segmented states.

AI summary
A vehicle control device includes a first inputter, a second inputter, a mode controller configured to, when the first inputter is operated by a user, determine a driving mode of a vehicle as a first mode, and when the second inputter is operated by the user in the first mode, switch the driving mode from the first mode to a second mode, and a driving controller configured to control at least one of a steering and speed of the vehicle, and the driving controller is configured to control a steering and speed of the vehicle and prohibit change of a path of the vehicle when the driving mode is the first mode, and control a steering and speed of the vehicle and change of the path of the vehicle is allowed when the driving mode is the second mode.
