Telematics Integration via Terminal Merging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telematics devices are costly and inconvenient, as they require separate installations in vehicles and lack integration with user-owned terminal devices, limiting their ability to provide advanced services like audio message reception, lane departure detection, and eco-index calculation for promoting safe and economical driving.
Innovation Solution
A telematics service system that links user-owned terminal devices with vehicle electronic control devices to provide integrated services such as audio message conversion, lane departure detection, and eco-index calculation, using communication and information processing functions to enhance user convenience and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate telematics device is installed in the vehicle, then basic telematics functions (GPS, traffic information, remote diagnosis) can be provided, but the cost burden on users increases and user convenience decreases
Solution Approach 1:
The patent combines the telematics device with the user's existing terminal device (smartphone, tablet, or navigation device) that they already possess. This merging eliminates the need for a separate dedicated telematics device, reducing costs while maintaining all necessary telematics functions including GPS positioning, traffic information provision, and remote vehicle diagnosis through the integrated terminal device
Solution Approach 2:
The terminal device serves multiple functions: it acts as both the user's personal communication/navigation device and the vehicle's telematics system. This multi-functionality allows the device to provide telematics services while leveraging the user's existing investment in the terminal device, thereby reducing overall system cost and improving convenience
2Loss of information
If text messages are displayed on the terminal device while driving, then information can be transmitted to the user, but the driver's attention is diverted and safe driving is compromised
Solution Approach 1:
The patent replaces the visual display mechanism with an audio output mechanism. Text messages that would normally be displayed on the terminal device screen are instead converted to speech and output through the vehicle's audio system or the terminal device's speaker, allowing the driver to receive message information without visually diverting attention from the road
Solution Approach 2:
The patent introduces an audio conversion intermediary that transforms text messages into spoken form. This intermediary process converts the message content from visual text format to auditory speech format, enabling the driver to perceive message information through hearing rather than sight, thus maintaining focus on driving while still receiving information
3Temperature
If the vehicle interior temperature is adjusted manually after the user boards, then temperature control is provided, but the user experiences discomfort during the waiting period
Solution Approach 1:
The patent implements preliminary temperature adjustment by detecting when the user approaches or boards the vehicle and automatically initiating climate control before the user actually enters. The system pre-adjusts the interior temperature based on external conditions and user preferences, so that when the user boards, the comfortable temperature is already established, eliminating the uncomfortable waiting period
4Reliability
If a dedicated telematics device is mounted in the vehicle, then telematics services can be provided, but the device complexity and installation burden increase
Solution Approach 1:
The patent merges the telematics functionality with the user's existing terminal device, eliminating the need for a separate dedicated device mounted in the vehicle. This combination simplifies the overall system structure while maintaining reliable telematics service provision through the integrated terminal device that the user already possesses and is familiar with
Data Source
AI summary
A telematics service system and a terminal predict a driving start time of a vehicle based on a driving pattern of a user, compare status information of the vehicle and a set temperature before the predicted driving start time of the vehicle, and generate a temperature control signal so that an interior temperature of the vehicle reaches the set temperature. The terminal is fixed inside the vehicle. A vehicle electronic control device attached to the vehicle collects the status information of the vehicle, provides the collected information to the terminal device, and controls a temperature adjustment device of the vehicle in accordance with the temperature control signal of the terminal device to adjust the interior temperature of the vehicle to reach the set temperature.
