Electric Mobility Start Control Using Brake Intent Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric mobility systems lack the ability to confirm a user's intention to start, leading to potential accidents and unsafe situations due to unintentional activation.
Innovation Solution
A method and system that determines a user's intention to start by monitoring brake operation, release, and optionally a start button, and converts the electric mobility into a standby state if no intention is detected, ensuring safe initiation only when the user intends to start.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electric mobility allows immediate start without intention confirmation, then the ease of operation is improved, but the safety and reliability deteriorate due to potential unintentional activation
Solution Approach 1:
The system performs preliminary detection of user start intention through brake operation monitoring and start button detection before allowing the motor to start. This preliminary action confirms the user's intent to start, preventing unintentional activation while maintaining operational ease through automatic detection mechanisms.
2Reliability
If the electric mobility implements start intention confirmation through brake operation monitoring, then the safety is improved, but the device complexity increases
Solution Approach 1:
The system utilizes existing brake operation signals and start button inputs that are already part of the electric mobility's normal control interface. By monitoring these existing signals through the controller, the system confirms start intention without requiring additional dedicated sensors or complex hardware, thus maintaining simplicity while improving safety.
3Reliability
If the electric mobility requires brake release detection for start confirmation, then the reliability is improved, but the ease of operation deteriorates
Solution Approach 1:
The system merges the start intention confirmation process with the existing brake control and start button operations. By combining multiple detection methods (brake operation, brake release, and start button detection) into a unified control logic within the existing controller, the system maintains ease of operation while reliably confirming user intent through the integrated detection approach.

AI summary
A method and system for controlling an electric mobility are provided. The method and system may determine whether a brake is operated in a stationary state in which the electric mobility is stopped; convert the state of the electric mobility from the stationary state into a brake operation state if it is determined that the brake is operated in the stationary state; determine whether the brake is released in the brake operation state; and convert the state of the electric mobility from the brake operation state into a standby state in which the mobility can be started if it is determined that the brake is released in the brake operation state.
