Interactive Autonomous Driving with Joystick-Guided Setpoint Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous driving systems either provide drivers with a false sense of control or abruptly switch from autonomous to manual mode, lacking a seamless and intuitive method for interactive vehicle guidance during autonomous operation.
Innovation Solution
A vehicle guidance controller detects driver inputs via a joystick or equivalent, determining setpoints for longitudinal and transverse vehicle guidance, allowing for autonomous control without leaving autonomous mode, and ignoring or delaying non-executable instructions for smooth operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the driver is given complete control over the vehicle during autonomous driving, then the driver's sense of control is improved, but the autonomous operating mode is interrupted and requires manual intervention
Solution Approach 1:
The patent introduces an intermediary input device (joystick or handle) that mediates between the driver's control inputs and the autonomous vehicle system. This intermediary allows the driver to provide guidance instructions without directly taking control, maintaining autonomous operation while giving the driver a sense of involvement and control through the mediator device.
2Ease of operation
If the system switches from autonomous mode to manual mode for driver intervention, then the driver can directly control the vehicle, but the transition disrupts the autonomous flow and reduces efficiency
Solution Approach 1:
The patent implements a dynamic control system where the vehicle operates continuously in autonomous mode while dynamically accepting and processing guidance instructions from the driver through the input device. The system dynamically adjusts its response to driver inputs without requiring mode transitions, maintaining continuous autonomous operation while incorporating driver guidance in real-time.
3Adaptability or versatility
If the driver provides detailed guidance instructions during autonomous driving, then the acceptance and usability of autonomous driving is improved, but the system complexity increases
Solution Approach 1:
The patent segments the driver's guidance instructions into distinct types (direction changes, speed changes, overtaking commands) and processes each type through dedicated detection and response mechanisms. This segmentation allows the system to handle diverse guidance inputs in a structured manner, providing high adaptability while managing system complexity through organized processing of different instruction categories.

AI summary
A method and device for interactive autonomous driving. A vehicle guidance controller is configured to detect, during operation of a vehicle in an autonomous operating mode, an order for intervention by a driver in a driving event on an input device, in particular a joystick. And, on denial of the order, the vehicle guidance controller is configured to determine at least one setpoint for the autonomous operating mode. The setpoint may influence a longitudinal guidance of the vehicle and/or a transverse guidance of the vehicle in the autonomous operating mode. The vehicle guidance controller is configured to control the vehicle autonomously in the autonomous operating mode depending on the setpoint.
