Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles may incorrectly determine user input on the accelerator pedal, leading to accidental release of autonomous driving control and potential accidents.
Innovation Solution
An apparatus and method that utilize a sensor to detect the input amount of the accelerator pedal and a controller to determine if the input is erroneous, allowing for controlled release or maintenance of autonomous driving modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the autonomous vehicle releases driving control when the accelerator pedal is pressed, then the user intervention response is improved, but erroneous input causes accidental release of autonomous driving control
Solution Approach 1:
The system changes the parameter of accelerator pedal input amount detection to distinguish between erroneous and intentional inputs. By detecting whether the input amount exceeds a predetermined threshold, the system can differentiate between accidental pedal activation and deliberate user intervention, thereby maintaining reliable autonomous driving control while still responding to genuine user inputs.
2Reliability
If the autonomous vehicle maintains driving control when the accelerator pedal is pressed, then the autonomous driving stability is improved, but the user intervention response is delayed
Solution Approach 1:
The system uses parameter changes in accelerator pedal input detection to determine whether to maintain or release autonomous driving control. By comparing the detected input amount against a predetermined value, the system can quickly identify genuine user interventions that exceed the threshold and respond appropriately, balancing both stability and responsiveness.
3Reliability
If the vehicle distinguishes between erroneous and intentional accelerator inputs, then the safety is improved, but the control system complexity increases
Solution Approach 1:
The system applies parameter change detection by monitoring whether the accelerator pedal input amount exceeds a predetermined threshold value. This simple parameter-based approach enables the system to distinguish between erroneous and intentional inputs without requiring complex analysis algorithms, thereby improving safety while minimizing increases in control system complexity.

AI summary
An apparatus for controlling driving of a vehicle including a sensor that detects an input amount of an accelerator pedal applied a user and includes a controller. The controller determines an erroneous actuation of the accelerator pedal based on the input amount of the accelerator pedal and determines whether to release autonomous driving according to whether the accelerator pedal is erroneously pressed or actuated. In technology that controls autonomous driving by remotely generating autonomous driving control values, it is possible to improve the functional safety of a vehicle by determining whether to release the autonomous driving by determining a user's erroneous input or actuation of the accelerator pedal.
