Vehicle Controller Driving Style Matching for Remote Mode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote driving technologies often cause discomfort for vehicle occupants due to differences in driving styles between the occupant and the remote driver, particularly when switching between manual, automated, and remote driving modes, leading to rough vehicle operation.
Innovation Solution
The remote driving system compares control signals from manual, automated, and remote driving modes over a predetermined period to ensure a smooth transition by matching the driving style of the remote driver with that of the occupant, allowing for a seamless switch between modes and reducing discomfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If remote driving mode is activated without style matching, then remote driving functionality is achieved, but occupant comfort deteriorates due to driving style differences
Solution Approach 1:
The system performs preliminary comparison of control signals between manual driving and remote driving modes before activating remote driving. By analyzing whether the remote driver's operation style matches the occupant's preferred style in advance, the system prevents discomfort from occurring, rather than reacting after the problem arises.
Solution Approach 2:
The system continuously monitors and compares control signals from both manual and remote driving modes, using this feedback to determine whether to permit remote driving activation. The comparison results provide real-time feedback on style compatibility, enabling dynamic control of remote driving functionality based on current driving conditions and style matching.
2Object-affected harmful factors
If driving style comparison is performed, then occupant comfort is improved, but system complexity increases due to additional control signal analysis
Solution Approach 1:
The vehicle controller performs multiple functions using the same control signal comparison mechanism: it both monitors driving styles for comfort optimization and manages the permission/activation of remote driving mode. This multi-functional approach avoids adding separate complex systems for each purpose.
Solution Approach 2:
The system changes the operational parameters of the vehicle controller by switching between permitting and restricting remote driving activation based on style matching results. Rather than adding complex hardware, the system dynamically adjusts control permissions and operational modes based on the comparison analysis.

AI summary
A vehicle controller that controls a vehicle having a first driving mode in which the vehicle travels according to a first control signal based on manual driving or automated driving, and has a second driving mode in which the vehicle travels according to the second control signal based on remote driving is provided, the vehicle controller including a signal comparing unit that compares, to a first control signal, a second control signal acquired by a second control signal acquiring unit while a vehicle control unit is controlling the travelling of the vehicle according to the first control signal, and a mode control unit that causes the vehicle to exit the first driving mode and enter the second driving mode when a comparison result by a signal comparing unit satisfies a predetermined condition.
