Vehicle HMI Control for Permissible Actions in Autonomous Driving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles with autonomous driving functions, drivers face challenges in accurately determining permissible actions during autonomous driving, as the need to monitor the travel environment is reduced, making it difficult for them to recognize and adhere to permitted actions.
Innovation Solution
An information presentation control device and function control device are implemented, featuring a permissible action determination unit and an information presentation content control unit, which present information to the driver about permissible actions and restrict non-permissible actions, ensuring the driver takes appropriate actions during autonomous driving by determining and managing permissible actions based on travel environment, driver state, and other factors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If autonomous driving function is implemented, then driver workload is reduced, but driver awareness of permissible actions deteriorates
Solution Approach 1:
The system performs preliminary determination of permissible actions before the driver needs to execute them. The permissible action determination unit identifies what actions the driver can take during autonomous driving based on travel environment and driver state, and this information is presented to the driver in advance through the information presentation device, ensuring the driver is aware before needing to act.
Solution Approach 2:
The system establishes a feedback loop where the information presentation control unit continuously monitors the driver's state and travel environment, determines appropriate permissible actions, and presents this information back to the driver. This closed-loop feedback ensures the driver receives timely information about what actions are permitted, maintaining awareness despite reduced workload.
2Ease of operation
If autonomous driving function is implemented, then monitoring requirement is reduced, but safety risk increases
Solution Approach 1:
The information presentation control device acts as an intermediary between the autonomous driving system and the driver. It translates complex system states and environmental conditions into simple, actionable information about permissible actions, enabling the driver to maintain safety awareness without requiring continuous active monitoring of the autonomous system.
Solution Approach 2:
The system replaces the need for mechanical/physical monitoring by the driver with an automated information presentation system. Instead of requiring the driver to actively monitor and interpret complex system states, the system automatically processes this information and presents only the relevant permissible actions to the driver, substituting automated information processing for human monitoring effort.
3Ease of operation
If information about permissible actions is presented, then driver guidance is improved, but information complexity increases
Solution Approach 1:
The information presentation control unit extracts only the essential information needed for driver guidance from the complex set of system states and environmental conditions. Instead of presenting all available data, it selectively extracts and presents only the permissible actions that are directly relevant to the driver's current situation, simplifying the information while maintaining guidance effectiveness.
Solution Approach 2:
The system applies local quality by tailoring the information presentation to the specific context and driver needs. The information presentation device adapts the content, format, and detail level of permissible action information based on the current travel environment, driver state, and specific situation, ensuring the information is appropriately complex for each local context rather than using a uniform approach.

AI summary
A human machine interface control unit as an information presentation control device is used in a vehicle having an autonomous driving function to perform a driving action on behalf of a driver, and controls an information presentation device configured to present information to the driver. The human machine interface control unit includes a permissible action determination unit configured to determine a permissible action that a driver is permitted to take among actions, other than a driving action, to be possibly taken by the driver when the autonomous driving function is implemented, and an information presentation content control unit configured to cause an information presentation device to present information related to a determination result of the permissible action.
