Remote Vehicle Control Terminal Gesture Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote parking systems require cumbersome touch interactions, such as tracing specific paths on a display, which can be bothersome and prone to accidental activation, limiting user convenience and safety.
Innovation Solution
A remote movement system with an operation terminal that allows users to control vehicle movement without tracing specific paths, using touch interaction conditions like sharp curves, distance, or speed, to ensure intentional and safe vehicle control, and includes features like obstacle detection and distance display for enhanced safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a predetermined specific path touch condition is required, then accidental activation is reduced, but user convenience deteriorates
Solution Approach 1:
The patent changes the touch interaction parameters from requiring a specific path to requiring specific motion characteristics (sharp curves, minimum distance, minimum speed). This allows the system to maintain reliability by detecting intentional gestures while improving ease of operation by allowing flexible finger movements without strict path constraints.
2Ease of operation
If simple touch interaction is allowed, then user convenience is improved, but accidental activation increases
Solution Approach 1:
The patent introduces dynamic motion criteria (sharp curves, minimum distance, minimum speed) that adapt to detect intentional gestures. These dynamic parameters allow simple touch interactions to be convenient while preventing accidental activation by requiring the touch to meet specific motion thresholds that accidental touches are unlikely to satisfy.
3Measurement precision
If specific path tracing is required, then activation accuracy is improved, but operation complexity increases
Solution Approach 1:
The patent extracts the essential characteristic of intentional gesture (sharp motion curves) from the complex requirement of tracing specific paths. By focusing only on the presence of sharp curves rather than the complete path geometry, the system maintains activation accuracy while significantly reducing operation complexity.

AI summary
A remote movement system of the invention comprises an operation terminal and a vehicle electronic control unit. The operation terminal includes a touch sensing portion which senses a finger of a user touching the touch sensing portion and a terminal electronic control unit configured to transmit a control execution command for requesting an execution of a remote movement control to cause a vehicle to move to a target position when movement of the user's finger touching the touch sensing portion satisfies a predetermined touch interaction condition. The vehicle electronic control unit is provided in the vehicle and configured to execute the remote movement control in response to receiving the control execution command from the terminal electronic control unit. The predetermined touch interaction condition does not include a condition that the user's finger moves, touching the touch sensing portion along a predetermined specific path.
