Smart Key Control Apparatus Power Level Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The presence of electromagnetic waves from nearby portable devices interferes with the communication between a smart key control apparatus and a smart key, leading to signal recognition errors or failure in authentication processes.
Innovation Solution
A smart key control apparatus that adjusts the power level of neighboring portable terminals by requesting them to enter a low power mode during authentication failures, allowing for stable communication by retransmitting wake-up signals and releasing the low power mode upon successful authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the smart key control apparatus communicates with the smart key in the presence of electromagnetic waves from portable devices, then the authentication process can proceed, but signal recognition errors occur and communication stability deteriorates
Solution Approach 1:
The patent detects electromagnetic wave interference from portable devices and converts this harmful factor into a beneficial control signal. When interference is detected during smart key authentication, the system automatically adjusts the power level of the portable terminal or requests it to enter low power mode, thereby transforming the interference source into a cooperative element that helps resolve the communication issue.
Solution Approach 2:
The system dynamically changes the power level parameter of the portable terminal based on detected electromagnetic wave interference. By adjusting the power level or requesting low power mode entry, the system modifies the operating parameters of the interfering device to eliminate signal recognition errors and restore stable communication between the smart key control apparatus and the smart key.
2Reliability
If the portable terminal power level is adjusted during authentication, then communication stability improves, but additional control signals and processing are required
Solution Approach 1:
The smart key control apparatus autonomously detects electromagnetic wave interference and self-manages the power level adjustment of portable terminals without requiring external intervention. The system monitors authentication signals, identifies interference sources, and automatically sends control signals to adjust power levels or request low power mode entry, thereby maintaining communication stability through self-service operations.
Solution Approach 2:
The system implements a feedback mechanism where the smart key control apparatus monitors authentication signals for errors caused by electromagnetic wave interference. When interference is detected, the system sends control signals to adjust portable terminal power levels and monitors the resulting authentication attempts. This closed-loop feedback continues until stable communication is achieved, balancing the added control complexity with improved communication reliability.

AI summary
An apparatus, a method, and a system are provided for controlling a smart key. The smart key control apparatus includes a smart key controller that is configured to transmit a wake-up signal for a smart key when a start-up command is detected in a start-off state of a vehicle and authenticate the smart key based on a response of the smart key that corresponds to the wake-up signal. In addition, a peripheral controller is configured to adjust a power level of a neighboring portable terminal when an authentication for the smart key fails and a communicator is configured to transmit and receive a signal between the smart key and the portable terminal.
