Autonomous Vehicle Interface Adapting Selection Options to Margin Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information presenting systems in autonomous vehicles do not consider the time required for drivers to make judgments and selections from presented information, leading to inadequate presentation of selection information based on vehicle conditions.
Innovation Solution
An information presenting device that calculates a selection margin time and adjusts the presentation of selection information based on this time, simplifying options for shorter times and providing more detailed choices for longer times, ensuring appropriate information is presented to the occupant considering the vehicle's conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If selection information is presented with multiple options, then the occupant's choice flexibility is improved, but the selection time required increases
Solution Approach 1:
The system dynamically adjusts the number of selection options presented to the occupant based on the calculated selection margin time. When time is充裕, more options are presented; when time is limited, fewer options are shown. This dynamic adaptation resolves the contradiction by making the selection interface flexible rather than static.
Solution Approach 2:
The system changes the parameter of selection information quantity based on the selection margin time. By calculating the time available and adjusting the number of options accordingly, the system optimizes between providing comprehensive choices and enabling quick selection, directly addressing the time-flexibility trade-off.
2Measurement precision
If detailed selection information is provided, then the decision accuracy is improved, but the processing time increases
Solution Approach 1:
The system adjusts the detail level of selection information based on the selection margin time parameter. When time permits, detailed information is provided for accurate decision-making; when time is constrained, simplified information is shown to enable faster processing. This parameter-based adaptation resolves the accuracy-time contradiction.
3Productivity
If the vehicle moves at high speed, then the productivity is improved, but the time for occupant selection decreases
Solution Approach 1:
The system dynamically adapts the selection interface to the vehicle's current speed and calculated selection margin time. At high speeds where selection time is limited, the system reduces the number of options and simplifies information display, enabling the occupant to make quick selections even during high-productivity travel periods.
Solution Approach 2:
The system performs preliminary calculation of the selection margin time based on vehicle speed and distance to the next action point. This advance calculation allows the system to prepare appropriate selection information in advance, adjusting the complexity and quantity of options before the occupant needs to decide, thus accommodating high-speed operation constraints.

AI summary
An information presenting device is mounted in an autonomous vehicle in which an action candidate for the vehicle to take is settable based on selection from presented selection information made by an occupant. The information presenting device sets the action candidate for the autonomous vehicle to take, calculates a selection margin time from a current time point to a time point at which the occupant should complete the selection from the selection information, sets the selection information based on the action candidate depending on the selection margin time, and presents the set selection information to the occupant.
