RSPA Lateral Parking Alignment Using Smart Key Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Remote Smart Parking Assist (RSPA) systems cannot adjust the lateral alignment of a parked vehicle, requiring drivers to manually maneuver the vehicle, which is inconvenient and inefficient.
Innovation Solution
A parking alignment adjustment apparatus comprising a receiving unit, determining unit, and control unit that allows drivers to remotely adjust the lateral position of a parked vehicle using a smart key, with sensors detecting the driver's motion and controlling the vehicle's movement within a specific parking area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional RSPA function is used for parking, then automatic steering and control is achieved, but lateral position adjustment after parking is impossible
Solution Approach 1:
The system dynamically switches between two distinct parking modes: initial automatic parking mode and subsequent lateral adjustment mode. The control unit detects driver motion direction and automatically activates the appropriate mode, enabling the system to adapt its functionality based on the current operational stage without requiring manual mode switching.
Solution Approach 2:
The system uses the driver's natural motion (walking direction) as the command input for lateral adjustment. The motion detection unit automatically interprets the driver's movement toward the left or right as an intent to adjust the vehicle's lateral position, eliminating the need for separate control inputs or complex user interfaces.
2Ease of operation
If driver manually maneuvers vehicle for lateral adjustment, then position can be changed, but considerable inconvenience and time are required
Solution Approach 1:
The system replaces manual mechanical maneuvering with an automated control system. The motion detection unit captures the driver's motion, and the control unit automatically executes the lateral adjustment through the vehicle's steering and drive systems, substituting the time-consuming manual forward-reverse-steer cycle with a single automated operation.
Solution Approach 2:
The system performs the lateral adjustment operation immediately after detecting the driver's motion intent, without requiring the driver to complete the full manual maneuvering sequence. The control unit calculates and executes the necessary steering and movement commands in advance based on the detected motion direction, significantly reducing the time required for position adjustment.
3Adaptability or versatility
If driver directly drives vehicle for lateral movement, then position adjustment is possible, but complex forward backward and steering processes are required
Solution Approach 1:
The system merges the detection of driver intent and the execution of lateral adjustment into a single integrated process. The motion detection unit and control unit work together to automatically translate the driver's simple motion into the appropriate steering and movement commands, combining multiple complex operations (steering, acceleration, deceleration) into one unified automated sequence.
Solution Approach 2:
The control unit acts as an intermediary between the driver's simple motion input and the vehicle's complex maneuvering output. It processes the motion detection data and automatically generates the coordinated steering and drive commands, serving as a mediator that simplifies the control interface while maintaining full vehicle control capability.
