Foldable Pedal Control for Autonomous and One-Pedal Driving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In autonomous driving mode, foldable pedals in vehicles are a safety concern as they can be accidentally manipulated, causing accidents, and in manual mode, the simultaneous pop-up of both pedals is inconvenient for one-pedal operation.
Innovation Solution
A method to control foldable pedals that hides both pedals in autonomous driving mode and allows either the accelerator or brake pedal to pop up in manual driving mode based on driver selection, using a signal generation and control system involving autonomous and manual driving mode switches and controllers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If both foldable accelerator pedal and foldable brake pedal are configured to pop up or hide simultaneously, then safety is improved by preventing accidental manipulation in autonomous driving mode, but driver convenience deteriorates when implementing one-pedal mode
Solution Approach 1:
The pedal control system is segmented into independent control channels. The accelerator pedal and brake pedal are controlled separately through individual pop-up/hide commands, allowing the driver to select one-pedal mode where only the accelerator pedal pops up while the brake pedal remains hidden, or both pedals pop up simultaneously for traditional operation
Solution Approach 2:
The pedal configuration is made dynamic and adjustable. The system transitions from a fixed simultaneous pop-up/hide mode to a flexible mode where each pedal can be independently configured. The controller dynamically adjusts pedal states based on driver selection, enabling adaptation between one-pedal and two-pedal operating modes
2Reliability
If foldable pedal device is hidden in autonomous driving mode, then safety is improved by preventing erroneous manipulation, but driver relaxation deteriorates due to lack of pedal visibility
Solution Approach 1:
Different visibility states are applied to different pedals based on local requirements. In autonomous driving mode with one-pedal selection, the accelerator pedal may remain visible while the brake pedal is hidden, providing localized visibility where needed while maintaining safety by hiding the brake pedal that could cause erroneous manipulation

AI summary
A method of controlling a foldable pedal device includes an operation of the foldable pedal device, in which both a foldable accelerator pedal and a foldable brake pedal are hidden in an autonomous driving mode, both the foldable accelerator pedal and the foldable brake pedal basically pop up in a manual driving mode, and a one-pedal mode may be implemented such that only one of the foldable accelerator pedal and the foldable brake pedal pops up in the manual driving mode according to a driver's selection.
