Driving Zone Display With Variable Time Axes for Mode Transitions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack a configuration to effectively inform drivers of the latest zone settings for automated and manual driving modes, especially in dynamic driving routes where settings may change due to accidents or engineering work.
Innovation Solution
An information processing apparatus and method that generate driving zone display data by linking multiple pieces of display data with different time axes, allowing identification of automated and manual driving zones on a vehicle's route, and presenting this data to the driver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple pieces of display data with different time axes are linked to show zone changes over time, then the driver is informed of latest zone settings accurately, but the device complexity increases
Solution Approach 1:
The display data is segmented into multiple pieces, each representing a different time axis or time period. Each segment shows zone settings for a specific time range, allowing the driver to understand how zones change over time without overwhelming complexity in a single display element.
Solution Approach 2:
The system adds a time dimension to the display by linking multiple pieces of display data with different time axes. This transforms the information from a static spatial representation to a dynamic temporal representation, enabling accurate information delivery about zone changes over time.
2Reliability
If zone information is provided early and continuously updated, then the driver has sufficient preparation time for mode switching, but the loss of time for processing and transmitting updates increases
Solution Approach 1:
Zone information is provided to the driver in advance before the actual mode switch is needed. The system displays future zone settings and timing information proactively, giving the driver sufficient preparation time to mentally prepare for the transition from automated to manual driving mode.
Solution Approach 2:
The system continuously updates zone information based on current vehicle position and upcoming route segments. This feedback mechanism ensures the driver receives real-time information about zone changes while efficiently processing only relevant updates rather than continuous data streams.
3Productivity
If automated driving mode is used on straight roads with sufficient width, then driving efficiency is improved, but the driver's attention and readiness for manual driving may deteriorate
Solution Approach 1:
The system provides advance notice to the driver about upcoming manual driving zones before the vehicle reaches them. This preliminary information delivery allows the driver to maintain efficiency during automated driving while being mentally prepared for the upcoming transition to manual mode, preventing attention deterioration.
Solution Approach 2:
The display system acts as an intermediary between the automated driving system and the driver. It translates complex zone setting information into understandable visual representations that inform the driver of upcoming transitions, maintaining driver readiness without interfering with automated driving efficiency.
Data Source
AI summary
A configuration that generates driving zone display data that allows identification of at least an automated driving allowed zone and a manual driving zone on a driving route of a vehicle and that presents the driving zone display data to a user (driver) is provided. A data processing section that generates driving zone display data that allows identification of at least an automated driving allowed zone and a manual driving zone on a driving route of a vehicle is included. The data processing section generates time linear display data representing time (t) and a display position (h) in a proportional relation for a proximate zone and a remote zone. The data processing section generates display data in which a distance per unit display length of the remote zone is made longer than a distance per unit display length of the proximate zone. Regarding an intermediate-distance zone between the proximate zone and the remote zone, the data processing section generates display data having a time axis that changes gradually at a predetermined rate from the first time axis corresponding to the proximate zone to a second time axis corresponding to the remote zone.
