Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking assistance systems struggle to reliably recognize manual parking procedures, leading to potential incorrect activation of assistance functions and critical situations in traffic.
Innovation Solution
A method that acquires both surroundings-specific and motor-vehicle-specific indicators to reliably recognize manual parking procedures, preventing incorrect activation of parking assistance functions by combining multiple indicators such as detected parking spaces, GNSS position, traffic signs, light sensors, and vehicle dynamics like steering angle and braking patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If only a single indicator is acquired to recognize parking procedure, then the system complexity is reduced, but the recognition reliability deteriorates leading to incorrect activation
Solution Approach 1:
The indicator acquisition system is segmented into multiple independent indicator channels (first indicator, second indicator, etc.), each detecting different aspects of parking procedure. This segmentation allows the system to maintain high reliability through multiple indicators while managing complexity by treating each indicator as a separate, modular detection element.
Solution Approach 2:
Multiple indicators characterizing the parking procedure are merged and evaluated together to form a comprehensive recognition decision. The control device combines information from different indicator sources (surroundings-specific and motor-vehicle-specific indicators) to achieve reliable parking procedure recognition, preventing incorrect activation through single-indicator misinterpretation.
2Reliability
If multiple indicators are acquired to reliably recognize parking procedure, then the recognition reliability is improved, but the system complexity increases
Solution Approach 1:
The control device is designed with multi-functionality to handle various types of indicators (surroundings-specific and motor-vehicle-specific). This universal indicator evaluation mechanism can process different indicator types through a unified evaluation framework, reducing the complexity increase that would otherwise result from implementing multiple specialized evaluation systems.
Solution Approach 2:
The system implements feedback mechanisms where the evaluation of multiple indicators continuously monitors and adjusts the parking procedure recognition state. This feedback loop ensures that the control device can reliably distinguish actual parking procedures from other driving situations, maintaining high recognition reliability while managing the complexity of multi-indicator evaluation through iterative refinement.
3Reliability
If parking assistance function is activated based on single indicator, then the activation speed is fast, but the activation accuracy deteriorates causing critical situations
Solution Approach 1:
The system performs preliminary acquisition of multiple indicators that characterize the parking procedure before making the activation decision. By gathering surroundings-specific and motor-vehicle-specific indicators in advance and evaluating them together, the system ensures accurate activation decisions are made with sufficient time, preventing critical situations while maintaining timely response.
Solution Approach 2:
The system dynamically adjusts evaluation parameters and thresholds based on the combination of multiple indicators. By changing the evaluation criteria according to the specific pattern of acquired indicators (both surroundings-specific and motor-vehicle-specific), the system achieves both high activation accuracy and efficient processing, balancing reliability with time constraints.
