Vehicle Control Apparatus Dynamic Notification Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle control apparatuses may fail to perform the intended traveling control changes based on surrounding conditions, leading to confusion among observers about the control actions being taken, which can hinder appropriate responses to the vehicle's state.
Innovation Solution
A vehicle control apparatus that determines and executes traveling controls (in-lane stop, road shoulder stop, or autonomous driving) based on surrounding conditions, with varying notification modes to inform observers of the specific control action, ensuring they can take appropriate actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the notification mode is determined in advance for each state (first state or second state) as in the conventional apparatus, then the notification system is simple and easy to implement, but the notification cannot accurately reflect the actual traveling control being performed due to surrounding conditions
Solution Approach 1:
The notification mode is changed from a static predetermined mapping to a dynamic selection based on actual traveling control execution. The control unit determines the notification mode according to the actual traveling control being performed (which may differ from the initial state-based prediction), ensuring the notification accurately reflects the real situation while maintaining implementation feasibility through rule-based dynamic adjustment.
2Productivity
If the traveling control is determined by the driver's state alone without considering surrounding conditions, then the control decision is simple and fast, but the traveling control may not be appropriate for the actual surrounding environment
Solution Approach 1:
The system performs preliminary determination of traveling control based on driver state, then executes surrounding condition verification. If the preliminary control is inappropriate for surrounding conditions, the system adjusts to a more suitable control. This two-stage approach maintains fast initial response while ensuring environmental adaptability through conditional adjustment.
3Loss of information
If the notification mode does not vary with the actual traveling control being performed, then people outside the vehicle cannot specify what control is being executed, but changing the notification mode for every possible control variation increases system complexity
Solution Approach 1:
The notification mode is tailored to the specific traveling control being executed. Different notification modes are assigned to different traveling controls (e.g., autonomous driving control versus emergency stop control). This localized customization ensures each control type has an appropriate notification without requiring a complex universal notification system, as the control unit selects from a predefined set of modes based on the active control.

AI summary
A vehicle control apparatus comprises a control unit that performs a traveling control, when a driver has fallen into an inappropriate state; and a notification device that performs a surround notification to notify a person around the vehicle of an execution of the traveling control. The control unit is configured to perform, as the traveling control, at least two of an in-lane stop control, a road shoulder stop control, and an autonomous driving control. When the driver has fallen into the inappropriate state, the control unit performs the traveling control that is selected based on a surrounding of the vehicle from among the above three controls, and causes the notification device to perform the surround notification in a mode that varies depending on the traveling control selected to be performed.
