Vehicle Locking Control System with Door State Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle door lock control systems often annoy occupants by incorrectly notifying them of forgotten power supply states due to unintentional touch operations with the lock sensor.
Innovation Solution
A vehicle locking and unlocking control system that includes a lock trigger, vehicle-side transmitter, mobile wireless terminal, locking controller, door state detector, and alarm controller, which determines the vehicle's power state and the mobile terminal's location to delay and prevent unnecessary alarm notifications when the door is open.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the alarm notification is activated when the lock trigger is operated and the power supply is on, then the system can notify occupants of forgotten power supply states, but it causes annoying notifications due to unintentional touch operations
Solution Approach 1:
The system performs preliminary verification by detecting whether the door is in the open state before activating the alarm notification. This preliminary action prevents unintentional touch operations from triggering annoying notifications while maintaining reliable notification for actual forgotten power supply states
Solution Approach 2:
The system uses door state detection as feedback to control the alarm notification. By continuously monitoring the door state and using it as a condition for alarm activation, the system distinguishes between intentional and unintentional lock trigger operations, thereby reducing annoying notifications while maintaining notification reliability
2Speed
If the alarm is activated immediately upon detecting the lock trigger operation, then the system responds quickly to potential forgotten power states, but it triggers false alarms during intended entry or exit operations
Solution Approach 1:
The system performs preliminary door state detection before activating the alarm, ensuring that the notification is only triggered when appropriate. This preliminary check prevents false alarms during entry or exit operations while maintaining quick response for actual forgotten power states
Solution Approach 2:
The system dynamically adjusts alarm activation based on real-time door state conditions. By making the alarm activation conditional on the door being closed, the system achieves both quick response and high accuracy, avoiding false alarms during dynamic entry/exit operations

AI summary
A vehicle locking and unlocking control system, comprising: a lock trigger that is provided outside a vehicle and outputs an output signal when operated by a person; a vehicle side transmitter is configured to transmit a transmission request signal according to reception of the output signal output by the lock trigger; a mobile wireless terminal is configured to transmit a response signal according to reception of the transmission request signal transmitted by the vehicle side transmitter; a vehicle side receiver configured to receive the response signal transmitted by the mobile wireless terminal; a locking controller configured to determine whether or not the response signal received by the vehicle side receiver is suitable for a unique identification signal of the vehicle and output a lock signal on the basis of a result of the determination and the reception of the output signal output from the lock trigger; a door lock mechanism configured to lock a door according to the lock signal output by the locking controller; a first determiner configured to determine whether a driving source for driving the vehicle is in an on state or a power supply of the vehicle is in an on state; a second determiner configured to determine whether or not the mobile wireless terminal is outside the vehicle; a door state detector configured to detect an open state of the door; an alarm output unit configured to output an alarm; and an alarm controller configured to cause the alarm output unit to output an alarm after it is determined by the first determiner that the driving source of the vehicle is in an on state or the power supply of the vehicle is in an on state, the output signal output from the lock trigger has been received, and a predetermined period of time has elapsed from a time when it is determined by the second determiner that the mobile wireless terminal is outside the vehicle, and cause the alarm output unit not to output the alarm when it is detected by the door state detector that the door is in the open state before the predetermined period of time elapses.
