Mobile Device Remote Parking via Touchscreen Motion Tracks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle remote-parking systems lack intuitive and user-friendly methods for initiating and controlling autonomous parking functions, particularly in scenarios where traditional controls are obstructed, such as parallel parking between vehicles or near structures.
Innovation Solution
A mobile device application that presents customizable continuous motion tracks on a touchscreen, allowing users to initiate remote parking by tracing a predefined path with their finger, with the direction and speed of the vehicle controlled based on the user's input, and provides warnings for maintaining the path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional remote-parking controls are used, then vehicle parking function is achieved, but user-friendliness and intuitiveness deteriorate in obstructed scenarios
Solution Approach 1:
The patent replaces traditional mechanical or button-based remote controls with a touchscreen interface that uses graphical motion tracks. Users interact by tracing paths on the screen rather than manipulating physical controls, substituting mechanical interaction with graphical touchscreen interaction that is more intuitive and easier to understand.
Solution Approach 2:
The patent creates a visual copy of the desired vehicle motion path on the touchscreen display. The motion track graphically represents the path the vehicle will follow, allowing users to see and verify the parking trajectory before execution, making the control system more transparent and user-friendly.
2Manufacturing precision
If precise vehicle control is achieved in challenging parking scenarios, then parking accuracy improves, but control difficulty increases
Solution Approach 1:
The system performs self-service by automatically calculating and displaying the motion track based on the user's simple gesture. Once the user traces a path on the touchscreen, the system autonomously determines the vehicle's parking trajectory and executes it, eliminating the need for the user to manually control steering, acceleration, and braking while achieving precise placement.
Solution Approach 2:
The patent implements visual feedback by displaying the motion track that shows the vehicle's intended path. The system provides continuous feedback during the parking maneuver, allowing users to monitor progress and make adjustments if needed, thereby achieving precise control without increasing operational difficulty.
3Speed
If continuous motion tracking is implemented, then vehicle control responsiveness improves, but system complexity increases
Solution Approach 1:
The patent implements dynamic motion tracking where the system continuously monitors the user's finger movement on the touchscreen in real-time. The motion track is updated dynamically as the user traces the path, and the vehicle control responds dynamically to the traced trajectory, creating a responsive and adaptive control system.
Solution Approach 2:
The touchscreen interface acts as an intermediary between the user's simple finger gesture and the complex vehicle control systems. The motion tracking algorithm processes the touch input and translates it into vehicle control commands, mediating between the simple user interaction and the complex multi-function control required for precise parking.

AI summary
Method and apparatus are disclosed for mobile device initiation of vehicle remote-parking. An example method for initiating vehicle remote parking includes presenting, via a touchscreen of a mobile device, a first motion track that is predefined by a user and continuous. The example method also includes detecting a travel point of the user on the touchscreen and initiating forward motion during remote parking of a vehicle in response to determining, via a processor, the travel point is moving in a clockwise direction within the first motion track.
