Vehicle Control Device Occupant-Aware State Transition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control devices fail to transition appropriately into a drive impossible state when there are vehicle occupants other than the driver, leading to discomfort and inefficient power management.
Innovation Solution
A vehicle control device with a state transition unit and occupant detection unit that adjusts the vehicle's state based on the presence of drivers and other occupants, allowing for different transition scenarios to ensure comfort and optimal power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the power supply to the drive source and accessories is deactivated when parking is intended and the driver is absent, then power consumption is reduced, but the comfort of non-driver vehicle occupants deteriorates
Solution Approach 1:
The system applies different quality states to different occupants by detecting their presence and roles. Driver absence triggers power reduction, but non-driver presence prevents complete deactivation of accessories, creating localized quality differences in power supply based on occupant status
Solution Approach 2:
The system continuously monitors occupant presence through detection units and uses this feedback to dynamically adjust the power supply state. The control unit receives real-time information about driver and non-driver occupants to determine the appropriate drive impossible state, creating a closed-loop feedback system
2Productivity
If the vehicle transitions to a drive impossible state without detecting non-driver occupants, then power management efficiency is improved, but the suitability of state transition control deteriorates
Solution Approach 1:
The system dynamically adjusts the drive impossible state based on real-time occupant detection results. Rather than using a fixed transition rule, the system adapts the power supply deactivation level according to whether non-driver occupants are present, making the state transition flexible and context-dependent
Solution Approach 2:
The system changes the parameter of power supply state based on occupant detection. When non-driver occupants are detected, the system maintains a higher power supply state compared to when no occupants are present, effectively using parameter changes to balance efficiency and suitability

AI summary
A vehicle control device includes a vehicle controller that, if a predetermined state transition condition is satisfied, makes a state transition of a vehicle from a drive possible state to a drive impossible state. The vehicle control device includes a vehicle occupant detection unit that detects a vehicle occupant in the vehicle. The vehicle controller makes the state transition to the drive impossible state that is different depending on a detection result from the vehicle occupant detection unit.
