Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brake systems with exposed brake pedals during autonomous driving compromise driver comfort and safety, and there is a need for a mechanism to adaptively adjust the brake pedal position based on vehicle operating modes.
Innovation Solution
A brake pedal moving device with a pedal simulator, motor, and power conversion mechanism that adjusts the brake pedal position using a simple structure, allowing it to be stored during autonomous driving and exposed during manual operation, while providing a reaction force and preventing rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the brake pedal is exposed toward the driver in the passenger space, then the driver can operate the brake pedal at any time, but the driver's riding comfort deteriorates during autonomous driving and the driver may be injured in a contact accident
Solution Approach 1:
The brake pedal is made movable between an exposed position (for manual driving operation) and a retracted position (for autonomous driving safety and comfort). The moving device allows the brake pedal to dynamically adjust its position based on the driving mode, transforming a static safety hazard into a dynamic solution that adapts to operational requirements.
2Object-affected harmful factors
If the brake pedal is retracted during autonomous driving, then the driver's riding comfort is improved and injury risk is reduced, but the driver cannot operate the brake pedal when needed
Solution Approach 1:
The system dynamically positions the brake pedal based on detected driving modes. When manual operation is detected or required, the brake pedal is moved to the exposed position, ensuring accessibility while maintaining safety during autonomous operation.
3Adaptability or versatility
If a complex brake pedal moving device is used to adjust brake pedal position, then the brake pedal can be adaptively adjusted, but the manufacturing and installation efficiency decreases
Solution Approach 1:
The moving device integrates multiple functions into a single mechanism: it provides positional adjustment, generates reaction force through the pedal simulator, and prevents rotation through the rotation preventing portion. This multi-functional integration achieves adaptability while maintaining manufacturing simplicity.
Solution Approach 2:
The device is divided into distinct functional modules: the motor unit for movement, the pedal simulator for reaction force, and the rotation preventing portion for stability. This segmentation allows for simplified manufacturing and assembly of each component while achieving the overall complex function of adaptive brake pedal positioning.
