Vehicle Pull-Out Steering Control for Smooth Manual Takeover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving assistance systems face challenges in safely transitioning from automated driving mode to manual mode during vehicle pulling out, often resulting in inappropriate stopping positions and potential collisions with other vehicles.
Innovation Solution
A driving assistance apparatus that includes an input section for sensor information and a control section to determine a movement path from a parking space to a road region, allowing automated steering while leaving accelerator control to the user, and smoothly switching to manual mode based on user steering input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle stops at the pulling-out completion position to switch from automated driving mode to manual driving mode, then the mode transition is completed, but the vehicle may collide with other vehicles and the stopping position is inappropriate
Solution Approach 1:
The system performs preliminary actions by having the user operate the steering wheel during automated driving to activate automated parking mode, and by pre-positioning the vehicle at an appropriate stopping position before mode transition. The control section is configured to stop the vehicle only when specific conditions are met (steering operation detected, vehicle at appropriate position), ensuring safe mode transition without collision risk.
2Ease of operation
If automated steering control is used during the entire movement path, then the user burden is reduced, but the user cannot smoothly take over control when needed
Solution Approach 1:
The system dynamically adjusts the level of automation based on user input. During the movement path, if the user performs a steering operation, the control section transitions from automated steering control to manual steering control, allowing smooth takeover. This dynamic switching ensures both reduced user burden during automated operation and user ability to take over when needed.
3Object-affected harmful factors
If the vehicle continues moving without stopping during mode transition, then collision risk is reduced, but the mode transition may not be completed smoothly
Solution Approach 1:
The control section continuously monitors feedback from the steering operation detection section to determine when to stop the vehicle for mode transition. The system stops the vehicle only when specific conditions are met: steering operation is detected, vehicle is at an appropriate position, and mode transition is required. This feedback-based control ensures both collision risk reduction and smooth mode transition completion.

AI summary
A driving assistance apparatus configured to support a driving of a vehicle at a time of pulling out of the vehicle, the driving assistance apparatus including: a control section configured to determine a movement path from a parking space to a predetermined position of a road region, and run the vehicle along the movement path on a basis of surroundings information of the vehicle when pulling out the vehicle from the parking space to the road region, wherein the control section leaves an accelerator operation for the vehicle to a user while automatically controlling a steering operation for the vehicle at least in a section in the movement path, and switches from an automated driving mode to a manual driving mode in response to the steering operation that is performed by the user when the vehicle travels in the section.
