Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If camera and sensor devices record image and sensor data of the leading vehicle's body movements, then the quantity of sensor data increases, but the processing complexity and computational requirements increase
Solution Approach 1:
The patent applies preliminary action by pre-training deep learning neural networks with extensive training data representing various vehicle body movements (acceleration, braking, lane changes, etc.). The classification categories and evaluation criteria are predetermined, allowing the system to rapidly process real-time sensor data without performing complex analysis during actual operation. This shifts the computational burden to the offline training phase rather than real-time processing.
Solution Approach 2:
The patent replaces traditional mechanical or rule-based sensor data processing systems with artificial intelligence and deep learning algorithms. Instead of using complex if-then rules or mechanical analysis methods to interpret sensor data, the system employs trained neural networks that automatically learn patterns and classifications from training data, significantly reducing the complexity of real-time processing while handling large quantities of sensor data.
2Measurement precision
If AI and machine image analysis algorithms are used to detect vehicle body movements, then the measurement precision of movement detection improves, but the device complexity increases
Solution Approach 1:
The patent implements preliminary action by extensively training deep learning neural networks with diverse training data that represents various driving conditions, vehicle types, and body movements. This pre-training process establishes the algorithm's precision before deployment, allowing the system to achieve high measurement precision in real-time applications without requiring complex runtime adjustments or calculations.
Solution Approach 2:
The patent applies parameter changes by using deep learning neural networks with adjustable parameters (weights and biases) that are optimized during training. The system transforms the complex problem of precise movement detection into a parameter optimization problem, where the neural network learns the optimal parameters from training data. Once trained, these parameters enable precise detection without requiring complex real-time computational processes.
3Speed
If real-time processing of image and sensor data is implemented, then the speed of hazard detection improves, but the use of energy increases
Solution Approach 1:
The patent applies preliminary action by pre-processing and pre-training the deep learning models offline before deployment. The neural networks are trained on extensive datasets in advance, so that during real-time operation, the system only needs to perform forward propagation through the already-trained network, which is computationally efficient. This allows rapid hazard detection while minimizing real-time energy consumption.
Solution Approach 2:
The patent implements partial action by processing only the most critical aspects of sensor data in real-time using the pre-trained model. The system focuses computational resources on detecting and classifying hazardous situations rather than analyzing all aspects of the driving environment in equal detail. This selective real-time processing reduces energy consumption while maintaining high detection speed for safety-critical events.
Data Source
AI summary
A method for detecting movements of a body of a first motor vehicle includes recording image and sensor data by a camera and sensor device of a second motor vehicle. The image and sensor data represent that part of the environment of the second motor vehicle that contains the first motor vehicle. The image and sensor data are forwarded to a data analysis device that detects movements of the body of the first motor vehicle and uses artificial intelligence algorithms and machine image analysis to process the image and sensor data to classify movements of the vehicle body. The classified movements of the vehicle body are assigned to at least one of a set of defined states. Output data from the determined state are generated for further use in an automated driving function and/or for a user interface.
