EV Air Conditioning Mode Switch Using Driver Entry Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users transitioning from internal combustion engine vehicles to electric vehicles experience dissatisfaction due to differences in the starting sequence during remote air conditioning, as the existing remote air conditioning technologies do not align with the starting procedures of electric vehicles.
Innovation Solution
A method and system for converting a reserved air conditioning mode to a start mode in an electric vehicle, which involves determining the completion of the driver's entry into the vehicle, searching for an authentication mechanism, and switching from the reservation mode to a start mode based on the authentication mechanism, thereby mimicking the starting sequence of conventional internal combustion engine vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If the air conditioning system is driven using a high-voltage relay without engine start-up, then the vehicle structure is simplified and emission is reduced, but the starting sequence becomes different from internal combustion engine vehicles causing user dissatisfaction
Solution Approach 1:
The system performs preliminary detection of driver entry through door sensor signals before executing the start sequence. By detecting when the driver has entered the vehicle and closing the door, the system prepares the authentication mechanism in advance, ensuring a smooth transition to the start mode without disrupting the emission-reduced high-voltage relay architecture.
Solution Approach 2:
An authentication mechanism is introduced as an intermediary between driver entry detection and vehicle start execution. This intermediary component (authentication module) processes the transition by verifying authentication information, thereby bridging the operational gap between the simplified high-voltage relay system and the user-expected starting sequence.
2Reliability
If the driver must attempt to start the vehicle by depressing the brake pedal and pressing the start button, then the high-voltage relay system operates correctly, but the operation becomes more complex compared to internal combustion engine vehicles
Solution Approach 1:
The system detects driver entry and authentication status in advance, preparing the vehicle start conditions before the driver actually attempts to start the vehicle. This preliminary preparation ensures that when the driver presses the start button, the high-voltage relay system is already configured correctly, making the operation reliable yet simple.
Solution Approach 2:
The system implements feedback through door sensors that detect when the driver has entered and closed the door. This feedback signal triggers the authentication mechanism and prepares the start sequence, creating a responsive system that adapts to driver actions while maintaining the reliability of the high-voltage relay operation.
3Extent of automation
If the authentication mechanism is implemented to detect driver entry, then the starting sequence can be automated, but the device complexity increases
Solution Approach 1:
The authentication mechanism operates autonomously by automatically detecting driver entry through door sensors and initiating the authentication process without requiring manual intervention. The system serves itself by monitoring its own state (door closed, driver present) and automatically transitioning to the appropriate mode, thereby achieving high automation with minimal additional complexity.
Solution Approach 2:
The authentication mechanism is integrated into the existing vehicle control system, serving multiple functions: detecting driver entry, verifying authentication, and triggering the start sequence. By making the authentication module multi-functional, the patent reduces overall system complexity while achieving automated starting sequence.

AI summary
An embodiment method for controlling an electric vehicle includes determining whether a function is operated in a reservation mode before a driver gets into the electric vehicle, determining whether the driver getting into the electric vehicle has been completed based on a preset condition, searching for an authentication mechanism inside the electric vehicle, and switching from the reservation mode to a start mode based on the authentication mechanism.
