Vehicle Lock Control via Movement Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle locks in shared mobility systems consume excessive power and have a shortened lifespan due to frequent locking and unlocking, and are often locked inadvertently when in use, leading to safety and operational issues.
Innovation Solution
A system and method that determines if there is a valid unlocking instruction and checks for vehicle movement using sensors, sending a locking instruction only when no valid instruction is received and the vehicle is moved, thereby keeping the lock in an unlocked state unless abnormal movement is detected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lock is frequently locked and unlocked to ensure vehicle security, then the safety of the shared vehicle is improved, but the power consumption increases and the lifespan of the lock is reduced
Solution Approach 1:
The lock control system dynamically adjusts its behavior based on real-time vehicle state detection. The processor continuously monitors vehicle movement through sensors and adaptively determines locking actions, transitioning from static frequent locking to dynamic conditional locking, thereby reducing unnecessary power consumption while maintaining security.
Solution Approach 2:
The system implements a feedback mechanism where the processor receives real-time information about vehicle movement status from sensors, processes this information, and accordingly controls the lock state. This closed-loop feedback system ensures locking only when necessary (when movement is detected), optimizing both security and power consumption.
2Reliability
If the lock is frequently locked and unlocked to ensure vehicle security, then the safety of the shared vehicle is improved, but the lifespan of the lock is reduced
Solution Approach 1:
The system dynamically determines lock control strategies based on actual vehicle conditions rather than following a fixed frequent locking schedule. By continuously monitoring movement status and adaptively controlling locking actions, the system minimizes unnecessary lock operations, thereby extending lock lifespan while maintaining adequate security.
Solution Approach 2:
Through real-time feedback from movement sensors, the system intelligently determines when locking is necessary. This feedback-driven approach prevents unnecessary locking operations that would wear out the lock mechanism, thereby extending its operational lifespan while still ensuring vehicle security when truly needed.
3Reliability
If the lock is automatically locked to prevent unauthorized access, then the security is improved, but the vehicle may be locked by mistake during legitimate use
Solution Approach 1:
The system performs preliminary detection of vehicle movement status before executing locking actions. By detecting movement as a prerequisite condition for automatic locking, the system ensures that legitimate use (which involves movement) prevents accidental locking, while unauthorized stationary access attempts can be secured.
Solution Approach 2:
The system uses real-time feedback from movement detection sensors to dynamically control locking behavior. When movement is detected during use, the lock remains unlocked; when no movement is detected and unauthorized access is suspected, locking is activated. This feedback mechanism eliminates accidental locking during legitimate use while maintaining security.
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
This approach reduces power consumption, extends the life of the locks, and prevents accidental locking during vehicle use, ensuring both safety and efficient operation by locking the vehicle only when necessary.
Implementation Method 1
obtain position signals from a position sensor mounted on the vehicle in real time; and determine whether the vehicle is stationary based on the position signals
Implementation Method 2
obtain rotation signals from a rotation sensor mounted on a wheel of the vehicle in real time; and determine whether the vehicle is moved based on the rotation signals

AI summary
The present disclosure relates to systems and methods for controlling a lock of a vehicle. The methods may include determining if there is a valid unlocking instruction when the vehicle is in a valid-unlocked state; determining if the vehicle is moved; sending a locking instruction to the lock upon the determination that: there is not a valid unlocking instruction, and the vehicle is moved; or keeping the lock in the valid-unlocked state.
