Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air conditioning control systems for vehicles lack comprehensive and reliable control options, often resulting in unintended battery discharge due to limited control capabilities and lack of real-time status data integration.
Innovation Solution
A method and system that utilize a mobile terminal to query and display status data from both air conditioning and vehicle buses, allowing for intelligent control command generation based on user input and vehicle conditions, including battery state and other vehicle parameters, via a gateway device for efficient and safe operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If air conditioning control is implemented using simple remote controls or basic mobile devices, then the control system is easy to operate, but the control reliability is poor and battery discharge cannot be prevented
Solution Approach 1:
The system queries status data from the vehicle bus (battery state, tank level, operating status) and air conditioning bus (device status, power consumption) before executing control commands. This feedback mechanism ensures that control actions are based on real-time vehicle conditions, preventing battery discharge and ensuring reliable operation.
Solution Approach 2:
The system performs preliminary queries of vehicle and air conditioning status data before generating control commands. By checking battery charge, tank level, and device status in advance, the system prepares appropriate control strategies that prevent harmful effects like battery discharge while maintaining ease of use through automated decision-making.
2Reliability
If comprehensive status data from multiple buses is queried and processed, then the control reliability and safety are improved, but the device complexity increases
Solution Approach 1:
The mobile terminal device serves multiple functions: it acts as a user interface for control, a data collection system querying both vehicle and air conditioning buses, a processing unit for generating control commands, and a display device for showing status information. This multi-functionality consolidates complexity into a single universal device rather than requiring separate specialized components.
Solution Approach 2:
The system uses standardized bus communication protocols (vehicle bus and air conditioning bus) as intermediaries to connect the mobile terminal with various vehicle components. These buses provide a unified interface for data exchange, simplifying the complexity of direct connections to multiple individual components while ensuring reliable data acquisition for control decisions.
3Productivity
If control commands are issued without checking vehicle status, then the operation is simple and fast, but battery discharge and unsafe operation occur
Solution Approach 1:
The system performs preliminary checks of battery charge level, tank level, and air conditioning device status before issuing control commands. This preliminary action ensures that control operations are safe and will not cause battery discharge or other harmful effects, while the automated nature of these checks maintains operational efficiency.
Solution Approach 2:
The system proactively prevents battery discharge by checking battery status and controlling air conditioning operation accordingly. The control logic includes preliminary anti-actions such as preventing heater activation when battery charge is low, or limiting operation duration, thereby counteracting potential harmful effects before they occur.
