Innovation Solution
A trainable transceiver system that includes a transceiver circuit, an output device, and a control circuit, which receives image data from a camera or remote device to determine the vehicle's position status and conveys information to the driver through the output device, using techniques like image processing and machine vision to assist in parking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single camera is used for park assist, then device complexity is reduced, but measurement precision and reliability deteriorate
Solution Approach 1:
The patent introduces a trainable transceiver as an intermediary device that receives image data from a single camera, processes it through machine vision algorithms, and translates it into actionable park assist information. This mediator enables a single camera to achieve multi-camera level functionality by adding intelligent processing layers that extract position, orientation, and distance information through pattern recognition and image analysis techniques.
Solution Approach 2:
The patent replaces traditional mechanical or multi-sensor positioning systems with an optical-based machine vision system. Instead of using multiple physical sensors or complex mechanical measurement devices, the system uses a single camera combined with software-based image processing to achieve accurate vehicle position detection, thereby reducing hardware complexity while maintaining measurement precision.
2Ease of operation
If a single camera is used for park assist, then ease of operation is improved, but difficulty of detecting and measuring increases
Solution Approach 1:
The trainable transceiver is equipped with self-training capabilities that allow it to automatically learn and adapt to different vehicle types, garage environments, and camera positions. The system performs self-calibration and automatic parameter optimization, eliminating the need for complex manual configuration and making the system easy to install and operate while handling complex detection tasks autonomously.
Solution Approach 2:
The system includes a training phase where the transceiver pre-learns the specific characteristics of the vehicle, garage layout, and camera geometry before actual park assist operation. This preliminary action prepares the system in advance, so that during normal operation, complex detection and measurement tasks are already optimized, reducing both installation complexity and operational difficulty.
3Measurement precision
If image processing techniques are used, then measurement precision is improved, but use of energy increases
Solution Approach 1:
The system uses periodic image capture and processing rather than continuous operation. The camera and transceiver activate at specific intervals or triggered by detected motion/events, performing image processing only when needed for position determination. This periodic operation maintains measurement precision for park assist functionality while significantly reducing overall energy consumption compared to continuous processing.

AI summary
A trainable transceiver for controlling a device and providing vehicle position information to a vehicle occupant includes a transceiver circuit, an output device, and a control circuit coupled to the transceiver circuit and the output device. The control circuit is configured to receive, using the transceiver circuit or a secondary transceiver, image data corresponding to a position of the vehicle. The control circuit is further configured to determine a vehicle position status based on the image data and to control the output device to convey information to the vehicle occupant based on the vehicle position status.
