Parking Exit Warning Display for Cross-Traffic Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers face challenges in recognizing vehicles crossing the parking space when leaving a parking space, especially when parking backwards, as existing driver assistance systems may not provide reliable warnings for objects on the adjacent roadway.
Innovation Solution
A method and device that generates an image display showing a plan view of the vehicle's area, visually representing the distance of external objects from the vehicle, allowing the driver to easily assess the current distance and relative position of approaching objects, with symbols and color coding indicating risk levels, and optionally including acoustic warnings and automatic braking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional warning systems are used to alert drivers of objects on adjacent roadways, then drivers receive basic distance information, but the driver cannot easily assess the current relative position and distance of approaching objects simultaneously
Solution Approach 1:
The patent transforms one-dimensional distance data into a two-dimensional top-down visual representation. The display shows the vehicle's own position and the detected object's position in a top-down view, with distance information represented as a visual distance on the display between the vehicle icon and object icon. This dimensional transformation allows drivers to simultaneously perceive both distance and relative position, solving the information loss problem while maintaining warning reliability.
2Measurement precision
If detailed sensor data is processed to determine precise distance measurements, then measurement precision is improved, but the complexity of the processing system increases
Solution Approach 1:
The patent creates a simplified visual copy of the real-world spatial situation on the display device. Instead of requiring complex processing of raw sensor data, the system generates a top-down view representation that copies the essential spatial relationships. The distance information is visually represented as the distance between icons on the display, providing precise measurement information through intuitive visual cues rather than complex data processing.
3Reliability
If the system provides comprehensive information about objects and distances, then driver awareness is improved, but the ease of operation and quick assessment is reduced
Solution Approach 1:
The patent employs color coding to represent different distance ranges and risk levels. The display uses color gradients or distinct color zones to indicate near, medium, and far distances, allowing drivers to quickly assess the situation at a glance. This visual encoding transforms comprehensive distance information into instantly recognizable color patterns, maintaining high driver awareness while enabling rapid situation assessment.

AI summary
The invention aims to specify a solution to the problem of how a driver of a motor vehicle (1), when exiting a parking space (18), can be especially reliably warned of the presence of a moving object (24) outside the vehicle on a roadway (23) adjoining the parking space (18). The object (24) is detected by means of sensors (5 to 9), and a current distance (26) of the object (24) from the motor vehicle (1) is determined from sensor data of the sensors (5 to 9). An image representation (27, 43, 64) is generated, which shows a plan view of at least one region of the motor vehicle (1') and in which the distance (26) of the object (24) from the motor vehicle (1) is optically presented. The image representation (27, 43, 64) is displayed on a visual display unit (3).
