Vehicle Jerk Pattern for Automated Driving Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automated driving systems face challenges in safely transitioning control from automated to manual mode, particularly when the operator is distracted, as they rely on visual, acoustic, and haptic warnings that may confuse or frighten the driver, risking an unsafe handover.
Innovation Solution
The method involves applying a jerk pattern to the vehicle's motion to subtly alert the driver, requiring them to intuitively counteract by steering or accelerating, thereby initiating a safer and more natural transition to manual control, with visual, acoustic, or haptic signals only after the driver has taken over.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional warning signals (visual, acoustic, haptic) are used to alert the driver for handover, then the driver is informed of the need for manual control, but the driver may become confused or frightened leading to unsafe handover
Solution Approach 1:
The system applies preliminary gentle jerks to the vehicle motion before the driver becomes fully aware of the handover need, subtly preparing the driver for manual control without causing sudden alarm or confusion
Solution Approach 2:
The warning system transitions from static traditional signals to dynamic motion-based warnings, where the vehicle itself provides the warning through controlled motion changes that the driver can intuitively sense and respond to
2Reliability
If multiple warning signals are output simultaneously to ensure driver awareness, then the driver is more likely to notice the handover need, but the driver may become overwhelmed and confused
Solution Approach 1:
The invention extracts the warning function from traditional HMI components (screens, speakers, vibration motors) and transfers it to the vehicle's motion control system, simplifying the warning mechanism to a single intuitive channel that the driver naturally responds to
Solution Approach 2:
The vehicle motion acts as an intermediary between the automated driving system and the driver, translating electronic control decisions into physical sensations that the driver intuitively understands and responds to without cognitive overload
3Reliability
If the vehicle provides immediate feedback when driver input is detected, then the driver receives confirmation of control takeover, but the automated driving control may interfere with manual control
Solution Approach 1:
The system applies preliminary gentle jerks that anticipate the driver's corrective input, creating a natural feedback loop where the driver's corrective steering or acceleration is met with complementary rather than conflicting automated responses
Solution Approach 2:
Instead of the automated system immediately counteracting driver input (traditional approach), the system inverts the approach by having the driver's input naturally override and cancel the automated jerks, providing clear confirmation of takeover without interference

AI summary
A method and an apparatus are proposed for controlling a vehicle being configured to operate under automated driving control. The control comprising: controlling a movement of the vehicle under automated driving control based on a target driving condition; monitoring, during controlling the movement of the vehicle under automated driving control, a hand-over criteria for determining whether a hand-over from automated driving control to manual driving control by an operator of the vehicle is required; and controlling the movement of the vehicle under automated driving control such as to apply a jerk pattern to the controlled movement of the vehicle when it is determined that a hand-over from automated driving control to manual driving control is required, wherein the jerk pattern comprises one or more jerks to change a longitudinal and/or lateral acceleration of the vehicle.
