Vehicle Height Control During Automatic Parking Maneuvers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic driving systems do not adequately address vehicle height adjustment when moving to or from a target parking position, limiting their effectiveness and user convenience.
Innovation Solution
A control device and method that includes an external environment recognition unit, a reception unit for user input, a movement control unit, and a height control unit, which work together to adjust the vehicle's height based on recognition data and movement progress, enabling appropriate height adjustments during automatic movement to and from a target position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If automatic parking control is implemented without height adjustment, then the automation function is simple and reliable, but the vehicle cannot adapt to different parking environments (such as speed bumps or low ceilings)
Solution Approach 1:
The height adjustment is performed in advance before the automatic parking movement begins. The control device calculates the required height based on recognition data of the parking environment (such as detecting speed bumps or low ceilings) and adjusts the vehicle height beforehand, ensuring the vehicle is properly positioned for the upcoming maneuver without adding complexity during the movement itself.
Solution Approach 2:
The vehicle height is made dynamically adjustable during the automatic parking process. The height control unit continuously monitors the movement progress and adjusts the vehicle height in real-time according to the current phase of parking (approach, positioning, final stop), allowing the system to adapt to different environmental conditions while maintaining a relatively simple base control architecture.
2Ease of operation
If height adjustment is performed during automatic movement, then user convenience is improved, but the control timing and coordination become more difficult
Solution Approach 1:
The control device implements a feedback mechanism where the height control unit continuously receives information about the automatic movement progress from the movement control unit. Based on this feedback, the system automatically adjusts the vehicle height at appropriate moments during the parking sequence, providing seamless user experience without requiring manual intervention. The feedback loop ensures proper coordination between height adjustment and movement phases.
Solution Approach 2:
The height control function is merged with the automatic parking control system rather than operating as a separate independent system. The control device integrates the height adjustment commands with the movement control commands, allowing both functions to be coordinated through a unified control logic that monitors overall parking progress and triggers appropriate actions automatically.
3Reliability
If height adjustment is synchronized with movement progress, then parking safety and comfort are improved, but the control precision requirements increase
Solution Approach 1:
Critical height adjustments are performed in advance before the vehicle reaches critical positions during automatic parking. For example, the vehicle height is adjusted before approaching speed bumps or before positioning near the final parking spot, ensuring safety margins are maintained. This preliminary action approach reduces the precision requirements for real-time synchronization during the actual movement.
Solution Approach 2:
The system uses dynamic height adjustment that adapts to the current phase of parking rather than requiring constant high-precision synchronization throughout the entire movement. Different height levels are maintained during different phases (approach phase, positioning phase, final stop), allowing the system to achieve reliable safety outcomes through phase-based control rather than continuous precision timing.
