Motor Vehicle Access Closure Sensor Control System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current access closure systems for motor vehicles lack efficient sensor-based control features for locking, unlocking, unlatching, opening, and closing, particularly in keyless entry scenarios, which limits their operational flexibility and user convenience.
Innovation Solution
A system comprising sensors mounted within or on components of the vehicle, signal processing circuits, and actuators that respond to detectable changes in sensor signals to control the access closure, enabling locking, unlocking, unlatching, opening, or closing operations, with multiple sensors and signal processing configurations for various control scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sensor-based control features are added to access closure systems, then operational flexibility and user convenience are improved, but device complexity increases
Solution Approach 1:
The system divides the access closure control into multiple independent sensor activation events, each triggering specific operations (locking, unlocking, unlatching, opening, closing). Each sensor or sensor group functions as an independent module that can be activated separately, allowing the system to achieve complex operational flexibility through segmented control rather than a monolithic control system.
2Ease of operation
If multiple sensors are used for different control scenarios, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The system employs multiple sensors that can serve different functions depending on their activation sequence and combination. The same sensor infrastructure supports various control scenarios including keyless entry, remote locking, and automated opening/closing operations. This multi-functional approach allows ease of operation across different scenarios without requiring entirely separate sensor systems for each function.
3Ease of operation
If sensor-based control is implemented for keyless entry, then ease of operation is improved, but reliability may worsen due to potential sensor errors
Solution Approach 1:
The system incorporates feedback mechanisms where sensor activation events trigger control signals that can be monitored and verified. The control system receives feedback from the access closure operations to confirm proper execution (locking, unlocking, unlatching, opening, closing). This feedback loop allows the system to detect and respond to sensor errors or malfunctions, maintaining reliability while preserving keyless entry convenience.

AI summary
A system for at least two of locking, unlocking, unlatching, opening or closing an access closure of a motor vehicle may include a plurality of sensors, each mounted to or within an access closure handle mounted to the access closure or to or within at least one component of the motor vehicle that is not an access closure handle, the plurality of sensors including first and second sensors configured to produce respective first and second sensor signals and to produce detectable changes in the sensor signals upon detection of at least one respective sensor activation event, one or more signal processing circuits configured to be responsive to the detectable changes in the sensor signals to produce respective control signals, and means responsive to the control signals to carry out at least two of locking, unlocking, unlatching, opening or closing of the access closure of the motor vehicle.
