Automated Driving Behavior Adjustment for Occupant Preferences
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automated driving systems often deviate from the preferred travel path and speed settings of vehicle occupants, causing discomfort and anxiety due to pre-determined behaviors that do not align with the occupants' preferences.
Innovation Solution
A vehicle control system that includes a processor and memory configured to adjust vehicle behaviors such as traveling position, speed, and acceleration based on occupant requests, using input units and a behavior adjustment unit to modify the automated driving system's settings in real-time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the automated driving system executes pre-determined behaviors, then the automation level is improved, but the adaptability to occupant preferences deteriorates
Solution Approach 1:
The system dynamically adjusts the degree of automation based on occupant preferences. The behavior adjustment unit modifies automated driving behaviors in real-time according to occupant requests, allowing the automation level to be flexible rather than fixed. This resolves the contradiction by making the automation adaptive to individual occupants while maintaining high automation capabilities.
Solution Approach 2:
The system changes behavioral parameters (traveling position, vehicle speed, acceleration) based on occupant preferences. By adjusting these parameters dynamically, the system maintains high automation while adapting to individual occupant needs, resolving the contradiction between automation level and adaptability.
2Device complexity
If the automated driving system uses pre-determined behaviors, then the system complexity is reduced, but the ease of operation deteriorates
Solution Approach 1:
The system implements feedback through occupant input units that capture preferences and requests. The behavior adjustment unit uses this feedback to modify automated driving behaviors, creating a closed-loop system that improves ease of operation without significantly increasing complexity. The feedback mechanism allows occupants to influence the system naturally.
Solution Approach 2:
The system provides self-service by automatically adjusting behaviors based on occupant inputs without requiring complex manual intervention. The behavior adjustment unit autonomously modifies parameters based on simple occupant requests, maintaining low complexity while improving ease of operation.
3Reliability
If the automated driving system maintains fixed behaviors, then the reliability is improved, but the adaptability deteriorates
Solution Approach 1:
The system transitions from fixed to dynamic behaviors while maintaining reliability. The behavior adjustment unit modifies automated driving parameters in real-time based on occupant preferences, but within safe and validated ranges. This dynamic adjustment maintains reliability through controlled changes while improving adaptability to individual occupants.
Solution Approach 2:
The system changes operational parameters (position, speed, acceleration) within validated ranges based on occupant preferences. These parameter changes maintain reliability by staying within safety boundaries while improving adaptability to individual occupant needs and preferences.

AI summary
A vehicle control system mounted on a vehicle includes an automated driving system configured to execute automated driving. The vehicle control system includes at least one processor and at least one memory storing computer program code. The at least one memory and the computer program code are configured, with the at least one processor, to cause the vehicle control system to carry out adjusting and acquiring. The adjusting is adjusting a behavior of the vehicle during execution of the automated driving. The behavior includes at least one of a traveling position in a width direction in a traveling lane, a vehicle speed, or an acceleration. The acquiring is acquiring behavior request information related to a behavior request for the behavior from an occupant of the vehicle. The adjusting includes adjusting the behavior determined by the automated driving system based on the behavior request information.
