Vehicle Control Module Activation for Damage Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic control units in vehicles consume energy even when the vehicle is in a key-off state, leading to battery discharge, and there is a need for efficient activation of control modules to monitor damage or provide services without draining the battery.
Innovation Solution
A system that includes sensors for damage detection, a camera module for identification, and a communication module to send activation signals to remote processors, which prioritize the activation of control modules based on battery charge level and location, ensuring minimal energy consumption and efficient data collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If control modules are activated to monitor and detect damage to the vehicle, then damage detection capability is improved, but battery energy consumption increases
Solution Approach 1:
The system performs preliminary actions by having the sensor continuously collect damage detection data even when the vehicle is off, and only activates the camera module when damage is detected. This preliminary data collection by the low-power sensor prepares the system for potential damage events without requiring continuous high-power operation of all components.
Solution Approach 2:
The system applies partial action by selectively activating only the camera module when damage is detected, rather than keeping all monitoring systems continuously active. The sensor operates continuously at low power, while the camera operates partially only when needed, optimizing the balance between detection capability and energy consumption.
2Measurement precision
If the camera module is continuously active to capture damage identification data, then damage identification accuracy is improved, but battery discharge increases
Solution Approach 1:
The sensor performs preliminary monitoring continuously and only triggers the camera when damage is detected. This preliminary action by the low-power sensor eliminates the need for continuous camera operation, achieving accurate damage identification only when necessary while minimizing energy loss.
Solution Approach 2:
The camera module operates periodically rather than continuously, activating only when the sensor detects potential damage. This periodic operation pattern maintains damage identification capability while significantly reducing battery discharge compared to continuous camera operation.
3Reliability
If multiple control modules are activated simultaneously for comprehensive monitoring, then monitoring completeness is improved, but energy consumption increases
Solution Approach 1:
The monitoring system is segmented into two distinct components with different power profiles: a low-power sensor that operates continuously for damage detection, and a high-power camera module that operates only when needed. This segmentation allows comprehensive monitoring capability while managing energy consumption through differentiated operation modes.
Solution Approach 2:
The system applies partial action by activating the camera module only when the sensor detects damage, rather than running all modules simultaneously. This selective activation maintains monitoring completeness for damage events while avoiding the excessive energy consumption of continuous full-system operation.

AI summary
Method and apparatus are disclosed for control module activation to monitor vehicles in a key-off state. An example system includes a vehicle at a location in a key-off state that includes a sensor for collecting damage detection data, a camera module including a camera for collecting damage identification data, and a communication module. The example system also includes a remote processor to receive the damage detection data from the communication module and detect damage to the vehicle based upon the damage detection data. The remote processor also is to send, responsive to detecting the damage, an activation signal to activate the camera.
