Valet Mode Air Purification Control for Eco-Friendly Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional valet modes in eco-friendly vehicles lack detailed control and do not consider the specific characteristics of electric or hybrid vehicles, leading to concerns about contamination and inconvenience, especially regarding air quality and disinfection before the primary driver takes over.
Innovation Solution
A method for controlling the valet mode in eco-friendly vehicles that includes determining vehicle takeover mode entry conditions, requesting and performing takeover controls to adjust limitations, such as air purification and ventilation, based on infectious disease risk, air quality, and user-selected criteria, to ensure a clean and safe interior before the primary driver takes over.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional valet mode with simple on-off control is used, then ease of operation is improved, but air quality control and contamination prevention are insufficient
Solution Approach 1:
The system performs preliminary air cleaning and purification actions automatically when valet mode is detected or before the primary driver returns. The controller activates the air conditioner in cleaning mode, runs the air purifier, and performs ventilation procedures in advance to ensure the interior is clean before the owner takes over the vehicle again.
Solution Approach 2:
The valet mode control system automatically detects when to initiate cleaning procedures and executes air quality management without requiring manual intervention from the primary driver. The controller monitors valet mode status and autonomously activates air conditioning, air purifiers, and ventilation systems to maintain cleanliness.
2Object-affected harmful factors
If detailed air cleaning and purification controls are implemented, then air quality and contamination prevention are improved, but device complexity increases
Solution Approach 1:
The air conditioner system is designed to perform multiple functions: normal climate control, air cleaning mode, and forced ventilation mode. The same air conditioner apparatus executes different operational modes based on controller commands, eliminating the need for separate dedicated cleaning devices and reducing overall system complexity.
Solution Approach 2:
The patent combines air cleaning, air purification, and ventilation functions into an integrated control system that manages the air conditioner, air purifier, and ventilation apparatus through a single controller. This unified approach simplifies the control architecture while maintaining comprehensive air quality management capabilities.
3Object-affected harmful factors
If multiple takeover controls are requested based on vehicle status, then air cleaning effectiveness is improved, but control complexity and user burden increase
Solution Approach 1:
The controller monitors vehicle status parameters such as window positions, door states, and air conditioner operation status to determine the appropriate cleaning sequence. Based on feedback from these sensors, the system automatically adjusts the execution of air cleaning, purification, and ventilation procedures, selecting optimal control strategies without requiring user input.
Solution Approach 2:
The control system dynamically adjusts the air cleaning procedure based on real-time vehicle conditions. If windows are already open, the system may skip forced ventilation; if the air purifier is already running, it adjusts the cleaning sequence accordingly. This dynamic adaptation optimizes cleaning effectiveness while simplifying user interaction.

AI summary
Disclosed are methods, apparatuses, and systems for controlling a valet mode of a vehicle. The method may include determining whether or not one or more vehicle takeover mode entry conditions are satisfied while a vehicle is in the valet mode, requesting one of a plurality of takeover controls for a vehicle takeover mode based on a determination that the one or more vehicle takeover mode entry conditions are satisfied and further based on a status of the vehicle, and performing the requested takeover control on the vehicle by adjusting a limitation that is applied, in the valet mode, to the vehicle.
