Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The inconvenience of manually determining the parking direction and trajectory for electric vehicles to align their charging ports with charging devices in varying parking lot configurations, which reduces user experience.
Innovation Solution
An automatic electric vehicle parking system that detects parking spaces and charging device locations, determines the optimal parking direction and trajectory to align the vehicle's charging port with the charging device, and guides the vehicle to the designated parking space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual parking determination is used, then the system complexity is reduced, but the ease of operation deteriorates due to the inconvenience of aligning charging ports with charging devices
Solution Approach 1:
The parking system automatically determines the parking direction and trajectory by itself, using the detected charging device location and vehicle charging port position to generate the optimal parking path without requiring manual user input or intervention
Solution Approach 2:
The manual mechanical parking operation is replaced with an automated control system that uses sensors to detect charging devices and a controller to compute and execute the parking trajectory, substituting human operation with electronic control and automation
2Ease of operation
If automatic parking system is implemented, then the ease of operation improves, but the device complexity increases due to additional sensors and control systems
Solution Approach 1:
The sensor system and controller are designed to perform multiple functions: detecting charging devices, determining vehicle position, calculating parking trajectory, and controlling vehicle movement, allowing a single integrated system to handle various parking scenarios without requiring separate dedicated components for each function
3Productivity
If charging device detection is added to parking process, then the productivity of charging operation improves, but the difficulty of detecting and measuring increases
Solution Approach 1:
The sensor acts as an intermediary between the vehicle and the charging device, detecting the charging device's location and transmitting this information to the controller, which then uses it to determine the optimal parking trajectory that aligns the charging port with the detected charging device

AI summary
An electric vehicle parking method includes generating sensing data by sensing surroundings of an electric vehicle. The method includes searching for vacant spaces using the sensing data. The method includes determining whether a vacant space of the vacant spaces is a parking space for electric vehicles, a parking space for conventional vehicles, or an unparkable space. The method includes selecting the determined parking space for the electric vehicles as a target parking space. The method includes detecting a position of an electric vehicle charging device corresponding to the target parking space. The method includes determining a parking direction and a parking trajectory of the electric vehicle for the target parking space so that a charging port of the electric vehicle is disposed closed to the position of the electric vehicle charging device. The method includes moving the electric vehicle to the target parking space along the parking trajectory.
