Vehicle Pre-Air Conditioning Control With Drive-Disabling Mode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems face challenges in balancing user convenience and security, particularly when performing pre-air conditioning remotely, as they often require restarting the engine after pre-air conditioning is initiated, which can lead to unauthorized vehicle operation.
Innovation Solution
A control apparatus and method that sets the vehicle to a drive-disabling mode during pre-air conditioning, allowing cancellation of this mode only when both the remote controller is present and a specific mode-cancelling operation is detected, ensuring the engine remains operational for the user to start the vehicle without unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the engine is stopped simultaneously with unlocking the doors during pre-air conditioning, then vehicle security is improved, but user convenience deteriorates
Solution Approach 1:
The patent implements a dynamic control mode that transitions between drive-disabling mode and normal mode based on detected operations. The system dynamically adjusts the engine control state: maintaining drive-disabling mode for security during pre-air conditioning, then switching to normal mode when authorized operations are detected, thereby resolving the contradiction between security and convenience
Solution Approach 2:
The system uses feedback from operation detection to control engine behavior. When unlocking or starting operations are detected during pre-air conditioning, the controller receives this feedback and automatically transitions from drive-disabling mode to normal mode, allowing the engine to continue running. This feedback mechanism ensures both security during pre-air conditioning and convenience when the user needs to operate the vehicle
2Ease of operation
If the engine is kept running during pre-air conditioning, then user convenience is improved, but vehicle security deteriorates
Solution Approach 1:
The patent applies preliminary anti-action by implementing drive-disabling mode before any unauthorized operations can occur. When pre-air conditioning is detected, the system proactively disables driving operations and stops the engine, preventing potential unauthorized use. This preliminary security measure is later overridden when authorized operations are detected
3Reliability
If drive-disabling mode is implemented during pre-air conditioning, then vehicle security is improved, but operational flexibility deteriorates
Solution Approach 1:
The system dynamically transitions between drive-disabling mode and normal mode based on detected operations, providing operational flexibility while maintaining security. The controller adapts the control mode in real-time: maintaining drive-disabling mode during pre-air conditioning for security, then switching to normal mode when unlocking or starting operations are detected, allowing the engine to continue running for authorized operations
Data Source
AI summary
A control apparatus for a vehicle disclosed herein is applied to a vehicle configured to perform pre-air conditioning of the interior of the vehicle by starting an internal combustion engine according to a remote control signal sent from a remote controller. When starting pre-air conditioning according to the remote control signal, the control apparatus sets the control mode of the vehicle to a drive-disabling mode, which is a control mode that disables an operation for driving the vehicle. If a specific mode-cancelling operation is detected in a situation in which the remote controller is present in the interior of the vehicle while the control mode of the vehicle is being set to the drive-disabling mode, the control apparatus cancels the drive-disabling mode while leaving the internal combustion engine operating.
