External Vehicle Data Access Without Engine Start
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems require occupants to physically board the vehicle and start the engine to access data stored in vehicle devices, limiting remote access and operation.
Innovation Solution
A vehicle system comprising a vehicle device and an external device that can operate independently and communicate with each other, allowing remote access to data without starting the vehicle, using a USB communication path or other wired/wireless connections, enabling data transfer and control between the vehicle device, external device, and external terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If occupants physically board the vehicle and start the engine to access data, then data access is enabled, but remote access capability is limited
Solution Approach 1:
The system divides the vehicle data access function into two independent parts: the vehicle device that collects and stores data, and the external device that provides remote access interface. This segmentation allows users to access data remotely through the external device without needing to physically board the vehicle or start the engine.
Solution Approach 2:
The external device acts as an intermediary between the vehicle device and external terminals. It receives data from the vehicle device and enables access from external terminals, serving as a bridge that allows remote access without requiring the vehicle to be active or the occupant to be present.
2Adaptability or versatility
If multiple function types are integrated into the vehicle device, then functionality is enhanced, but development complexity increases
Solution Approach 1:
The system separates core vehicle functions from additional data access functions by implementing an independent external device. This allows the vehicle device to maintain its original simple function set while the external device provides enhanced functionality including remote data access, thereby reducing development complexity for each component.
Solution Approach 2:
The external device is designed as a universal platform that can access and manage multiple types of data from various vehicle devices. This multi-functional external device reduces the need to develop separate systems for different data access requirements, thereby reducing overall development complexity.
3Loss of information
If the vehicle device is started to access data, then data retrieval is enabled, but energy consumption increases
Solution Approach 1:
The external device enables data access to be prepared and executed in advance without starting the vehicle. Users can retrieve data while the vehicle is parked and the engine is off, eliminating the energy consumption associated with starting the vehicle solely for data access purposes.
Data Source
AI summary
A vehicle system includes: a vehicle device; and an external device that is operable alone and communicably connected to the vehicle device. The external device receives data from the vehicle device and enables an access from an external terminal that changes the received data. According to the vehicle system, it is possible to access data obtained from the vehicle device without a person boarding a vehicle, without starting the vehicle device, and with remote operation.
