Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle security systems indiscriminately execute lighting and imaging processes regardless of the situation, which can be inconvenient for users.
Innovation Solution
A vehicle system that includes sensors, cameras, and an illuminating unit, controlled by processing circuitry to determine the presence of objects within specific ranges and adjust lighting and imaging operations accordingly, allowing user-defined settings and differentiated control based on detected objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the same security process is executed regardless of the situation, then the security coverage is comprehensive, but the user convenience deteriorates
Solution Approach 1:
The patent applies local quality by differentiating the security process into two distinct ranges: a first range (closer to vehicle) and a second range (farther from vehicle). When an object is detected in the first range, the system executes a first security process; when detected in the second range, it executes a different second security process. This localized differentiation allows the system to provide appropriate security measures for each situation, improving user convenience while maintaining comprehensive security coverage.
2Reliability
If the illuminating unit and camera are activated for all detected objects, then the security monitoring is thorough, but the power consumption increases
Solution Approach 1:
The patent applies parameter changes by modifying the operational parameters of the illuminating unit and camera based on the detected object's range. When an object is detected in the first range, the system activates the illuminating unit and camera with specific illumination intensity and capture frequency. When an object is detected in the second range, the system uses different illumination intensity and capture frequency settings. This dynamic parameter adjustment ensures thorough security monitoring while optimizing power consumption according to the actual security situation.
3Reliability
If the security process is executed indiscriminately, then the security response is consistent, but the user disturbance increases
Solution Approach 1:
The patent applies segmentation by dividing the security response into distinct processes based on the detected object's range. The security process is segmented into a first security process for objects in the first range and a second security process for objects in the second range. This segmentation allows the system to provide consistent and appropriate security responses tailored to each situation, reducing unnecessary user disturbance while maintaining reliable security coverage.

AI summary
A security system includes a camera, an illuminator, and a controller. The controller determines whether a first condition is met. The first condition includes a requirement that a moving object has been detected within a first range while a vehicle is parked. The controller determines whether a second condition is met. The second condition includes a requirement that the moving object has been detected within a second range, which is narrower than the first range, while a vehicle is parked. The controller is configured to change one or more controls selected from a control of determining whether to perform recording with the camera, a control of turning on or off the illuminator, and a control of an illuminance of the illuminator, between a state in which the first condition is met but the second is not, and a state in which both the first and second conditions are met.
