Remote Vehicle Control via ECU Server Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional vehicles require manual operation for controlling devices like air conditioners and windshields, leading to uncomfortable temperatures and ice/frost issues, and current remote vehicle control systems have limited automation.
Innovation Solution
A remote vehicle control system comprising a mobile terminal, ECU, and server, where the mobile terminal sends control instructions via the server to the ECU to start the engine and adjust electronic devices like air conditioners and windshields before the next travel, enhancing automation and user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation is used to control vehicle devices, then device complexity is reduced, but user convenience and comfort deteriorate due to delayed temperature adjustment and ice/frost removal
Solution Approach 1:
The system performs preliminary actions by allowing users to set control instructions in advance (e.g., desired temperature, time of arrival). The server automatically executes these instructions before the user arrives at the vehicle, pre-adjusting the air conditioner and other devices to ensure comfort without requiring manual operation at the moment of arrival.
Solution Approach 2:
The system enables self-service by automatically executing pre-set control instructions without requiring manual intervention. The server monitors conditions (time, location, weather) and autonomously activates devices like air conditioning, seat heating, and windshield defrosting based on previously configured user preferences, making the system serve itself rather than requiring continuous user input.
2Extent of automation
If remote control systems use simple internet technology, then device complexity is reduced, but automation level deteriorates
Solution Approach 1:
The system implements feedback mechanisms where the server continuously monitors vehicle conditions, user location, time, and weather data. Based on this feedback, the server dynamically adjusts and executes control instructions, automatically determining when and how to activate various vehicle devices to achieve optimal comfort and energy efficiency.
Solution Approach 2:
The server platform provides multi-functional capabilities by integrating multiple control functions (air conditioning, heating, defrosting, lighting) into a single universal system. This universal controller can handle various vehicle devices and scenarios through a unified interface, increasing automation without proportionally increasing overall system complexity.
3Temperature
If the air conditioner is not turned on in advance, then energy consumption is reduced, but user comfort deteriorates due to prolonged exposure to extreme temperatures
Solution Approach 1:
The system performs preliminary temperature adjustment by calculating the optimal time to activate the air conditioner based on user travel plans and current conditions. The air conditioner is turned on in advance of the user's arrival, allowing the interior temperature to reach the desired comfort level before the user enters, thereby avoiding energy waste from prolonged operation while ensuring comfort.
Solution Approach 2:
The system uses periodic action by activating the air conditioner only during necessary periods (before user arrival) rather than continuous operation. The server monitors conditions and activates devices periodically based on predicted usage patterns, optimizing the balance between comfort and energy consumption by running systems only when needed.
