Vehicle Lock Control via Wheel Status Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the context of vehicle sharing services, there is a need for a system that can safely and conveniently lock vehicles without causing sudden stops, which could lead to traffic accidents, especially when users forget to lock the vehicle or remotely lock it while it is in motion.
Innovation Solution
A system comprising a control device and a wheel status detection unit that determines the status of the vehicle's wheel, only executing a locking instruction when the wheel is in a static state, using speed sensors and a timer to ensure the vehicle is not in motion before locking, and including a central controller for sending locking or unlocking instructions directly to the lock.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote locking control is implemented for shared vehicles, then user convenience is improved, but safety deteriorates due to risk of traffic accidents when vehicle is in motion
Solution Approach 1:
The system performs preliminary detection of wheel status (motion or static) before executing the locking instruction. The control device queries the wheel status detection unit to determine whether the wheel is in motion or static state, and only executes locking when the wheel is confirmed to be static, thereby preventing accidents before they occur
Solution Approach 2:
The system establishes a feedback loop where the control device continuously monitors wheel status through the wheel status detection unit. The detection result (motion or static) is fed back to the control device, which uses this information to decide whether to execute locking, creating a closed-loop safety mechanism
2Reliability
If wheel status detection is performed repeatedly to ensure safety, then accident prevention is improved, but system complexity increases
Solution Approach 1:
The wheel status detection unit serves multiple functions: it detects wheel motion status, provides feedback to the control device, and enables the control device to make informed locking decisions. This multi-functional design reduces overall system complexity while maintaining high reliability
Solution Approach 2:
The wheel status detection unit acts as an intermediary between the control device and the locking mechanism. It provides critical status information that mediates the decision-making process, allowing the control device to safely execute locking only when appropriate without adding complex control logic
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Prevents traffic accidents by ensuring the vehicle is stationary before locking, enhancing user safety and preventing loss of the vehicle, while also providing a convenient and secure locking mechanism for shared vehicles.
Implementation Method 1
The wheel status detection unit may include or be operably coupled to a speed sensor

AI summary
The present disclosure provides a system and method for controlling a lock of a subject. The system may obtain an instruction for locking the subject. The system may obtain a status of the subject. The system may control the lock of the subject based on the instruction and the status of the subject. In response to a determination that the subject is in a motion status, the system may repeatedly update the status of the subject until an updated status of the subject is a static status. The system may lock the subject by controlling the lock of the subject based on the instruction and the static status of the subject.
