Vehicle Object Measurement for Height-Based Collision Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle systems fail to effectively detect and respond to smaller objects and road infrastructure elements, leading to potential collisions and damage during parking or driving, as they do not dynamically analyze measurable attributes like height relative to the vehicle's threshold values.
Innovation Solution
The implementation of a vehicle system that uses on-board sensors to dynamically detect and analyze measurable attributes of road infrastructure elements, such as height, length, and width, and automatically control the vehicle to avoid collisions by comparing these attributes with predetermined threshold values, enabling maneuvers like steering and braking to prevent contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicle sensors detect objects at particular height and distance, then the sensing function operates, but the sensing is momentary and not recorded or learned, failing to prevent collisions with smaller objects and road infrastructure elements
Solution Approach 1:
The system performs preliminary detection of road infrastructure elements and stores their spatial information in advance. When the vehicle approaches these pre-identified objects, the system retrieves the stored data and executes avoidance maneuvers before collision occurs, transforming momentary sensing into predictive action
Solution Approach 2:
The system establishes a feedback loop where sensor data about road infrastructure elements is continuously recorded, stored, and reused for subsequent detection and avoidance decisions. This creates a learning mechanism where past sensing information informs future collision avoidance actions
2Adaptability or versatility
If the vehicle uses pre-existing on-board sensors for multiple functions, then sensor utilization is maximized, but the sensors fail to dynamically analyze measurable attributes like height relative to threshold values for safety functions
Solution Approach 1:
The patent makes existing multi-functional sensors serve an additional safety function by extracting height measurements and comparing them against stored threshold values for road infrastructure elements, enabling collision avoidance without adding dedicated detection hardware
Solution Approach 2:
The system changes the operational parameters of existing sensors by dynamically analyzing measurable attributes (height, distance) and comparing them against threshold values, transforming generic sensing data into precision safety-critical measurements
3Reliability
If the vehicle automatically controls steering and braking to avoid overhead objects, then collision avoidance is achieved, but the system requires dynamic detection and analysis of multiple measurable attributes
Solution Approach 1:
The system pre-stores threshold height values and spatial information for road infrastructure elements before the vehicle encounters them. This preliminary preparation simplifies real-time decision-making by reducing complex environmental analysis to simple comparisons between current sensor data and pre-stored thresholds
Solution Approach 2:
The patent introduces a data processing intermediary layer that bridges raw sensor measurements and vehicle control actions. This intermediary performs height comparisons and generates avoidance commands, decoupling the complexity of multi-attribute analysis from both the sensors and the final control execution
