Trainable Transmitter for Vehicle Wireless Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle-based wireless control systems face challenges in configuring for universal use with various remote devices and systems due to differences in transmission schemes, making it difficult to maintain compatibility with new devices and systems.
Innovation Solution
A trainable transmitter system that determines a bit pattern of a received control signal without decoding it, identifies a second transmission scheme different from the first, and stores it for user-selectable transmission, allowing it to generate and transmit control signals using the new scheme, ensuring compatibility with a wider range of devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a vehicle wireless control system is configured for universal use with various remote devices, then the adaptability and versatility improve, but the device complexity increases due to multiple transmission schemes
Solution Approach 1:
The system performs self-configuration by automatically detecting the transmission scheme of the remote device and configuring itself accordingly, eliminating the need for manual setup by the user
Solution Approach 2:
The system changes its transmission parameters dynamically based on the detected remote device type, adapting the transmission scheme to match the target device automatically
2Adaptability or versatility
If the system stores multiple transmission schemes for different remote devices, then the adaptability improves, but the memory requirements and system complexity increase
Solution Approach 1:
The system uses a universal configuration approach where a single transceiver can operate with multiple transmission schemes by automatically detecting and adapting to the remote device type, eliminating the need for separate dedicated transceivers for each device type
Solution Approach 2:
The system copies the transmission scheme characteristics from the detected remote device and uses this information to configure its own transmission parameters, rather than storing complete protocol implementations
3Measurement precision
If the system attempts to decode control signals to identify transmission schemes, then the measurement precision improves, but the processing time and energy consumption increase
Solution Approach 1:
The system extracts only the essential identifying characteristics from the control signal (such as bit pattern or frequency) without performing complete decoding, enabling rapid identification of the transmission scheme while minimizing processing time

AI summary
Control systems for mounting in a vehicle are configured for transmitting a control signal to a receiver associated with a remote device. A control system receives a first control signal associated with a first transmission scheme. The system determines a bit pattern of the first control signal, and, based on the determined bit pattern, the system determines a second transmission scheme.
