Single-Pedal Braking Control Using Route-Aware Pedal Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The driving mode with a single pedal in advanced vehicles, which controls acceleration and braking through the accelerator pedal, is inconvenient and uncomfortable for drivers due to the inability to mimic the subtle control of braking by releasing the pedal, a habit ingrained in traditional driving practices.
Innovation Solution
A control system that integrates a pedal with a return mechanism, a control unit, and transducers to detect pedal movements, determining acceleration and braking parameters, and adjusts braking based on road and traffic conditions using ADASIS protocols and machine learning algorithms to optimize energy efficiency and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the driving mode with a single pedal is implemented to maximize energy efficiency, then energy recovery during braking is improved, but driving convenience and comfort deteriorate due to the inability to perform subtle braking control by simply releasing the pedal
Solution Approach 1:
The system dynamically adapts the braking behavior based on detected driving habits. The control unit learns the driver's preferences over time and adjusts the braking intensity and timing accordingly, making the single-pedal system progressively more comfortable and intuitive for each specific driver while maintaining energy efficiency
Solution Approach 2:
The system incorporates feedback loops where the control unit continuously monitors pedal usage patterns, detects driving habits, and adjusts braking parameters based on this information. This feedback mechanism allows the system to optimize both energy recovery and driving comfort iteratively
2Device complexity
If the braking is controlled solely by the accelerator pedal release in single pedal mode, then the system complexity is reduced, but the adaptability to different driving styles and conditions deteriorates
Solution Approach 1:
The control unit automatically detects and learns the driver's habits without requiring manual programming or adjustment. The system serves itself by autonomously adapting to the driver's preferences through continuous monitoring and analysis of pedal usage patterns, maintaining simplicity while achieving high adaptability
Solution Approach 2:
The system changes braking parameters (intensity, timing, duration) based on detected driving habits and conditions. By dynamically adjusting these parameters rather than using fixed braking behavior, the system achieves versatility across different driving styles while keeping the physical control mechanism simple

AI summary
A process for controlling the forward movement of a motor vehicle with a braking device, a control operable between a rest position and an end position, and return means for automatically returning the control to the rest position by a return movement includes the steps of determining at least a first parameter being characteristic of the return movement, determining one or more additional parameters, each of which is representative of one among a morphological state, a regulatory state, a traffic state, and a kinematic state of a portion of the road in front of the motor vehicle, and braking the motor vehicle by controlling the braking device as a function of the first parameter and of the determined additional parameters.
