Solution Overview
Problem
Modern parking assistance systems fail to accurately detect objects at higher levels, such as roof boxes in garages, limiting their ability to determine a reliable and accurate space for vehicle parking.
Innovation Solution
A device and method utilizing a sensing unit with optical sensors and a surround view system to create a three-dimensional map of the vehicle environment, including spatial coordinates of objects, allowing for the detection of both ground-level and overhead objects, and determining a drivable space based on vehicle dimensions, with the option for automatic guidance to a target position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional parking assistance systems monitor only the area around the vehicle in the vicinity of the highway, then the system complexity is reduced, but objects located at higher levels such as roof boxes in garages are not detected properly
Solution Approach 1:
The patent transitions from traditional 2D planar monitoring to 3D spatial monitoring by introducing vertical dimension detection. The sensing unit is configured to detect objects not only in the horizontal vicinity but also at elevated positions above the vehicle, creating a three-dimensional detection volume that captures overhead objects like roof boxes while maintaining manageable system complexity through integrated sensor arrays.
2Reliability
If optical sensors and surround view system are used to create a three-dimensional map, then object detection reliability is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple sensing elements including optical sensors, cameras, and surround view system components into an integrated sensing unit. These diverse sensors are merged to collectively create a three-dimensional map of the environment, where each sensor type complements the others to improve overall detection reliability while sharing processing infrastructure to manage complexity.
Solution Approach 2:
The sensing unit is designed with multi-functional capabilities, where the same sensor array serves multiple purposes: detecting overhead objects, mapping the surrounding environment, determining drivable spaces, and identifying parking positions. This universal approach allows a single complex sensing unit to perform various functions that would otherwise require separate systems.
3Measurement precision
If the system determines drivable space based on spatial coordinates and vehicle dimensions, then parking space determination accuracy is improved, but the calculation complexity increases
Solution Approach 1:
The system performs preliminary actions by pre-storing vehicle dimension data and pre-processing spatial coordinate information from the sensing unit. Before determining the drivable space, the determining unit has already prepared the necessary parameters including vehicle length, width, height, and turning radius, which are then combined with the three-dimensional map data to calculate the available parking space and target positions.
