Reverse Parking Speed Control Near Hidden Parking Stops
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers face challenges in controlling their vehicles when reversing into parking spaces due to the occlusion of the vehicle body, leading to potential collisions with parking stops, excessive impact, and a poor riding experience.
Innovation Solution
A vehicle control method and device that determine if a vehicle is performing a reverse parking maneuver based on gear, environment, and speed information, and adjust the reversing speed and suspension damping accordingly to prevent collisions and improve control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the vehicle body occludes the parking stops to prevent direct visibility, then the parking stops can be positioned at a low position under the vehicle, but the driver cannot know the specific position of the parking stops when reversing, making it difficult to react to avoid collision
Solution Approach 1:
The system performs preliminary detection of the parking stop position using sensors before the vehicle reaches it during reversing. The control system then proactively adjusts the reversing speed based on this advance information, allowing the driver to react without needing to visually see the parking stops.
Solution Approach 2:
The system continuously monitors the vehicle's reversing speed and position relative to the detected parking stops, and provides feedback by adjusting the reversing speed in real-time. This closed-loop control ensures the vehicle maintains a safe speed that allows for collision avoidance even when the parking stops are not visible to the driver.
2Productivity
If the vehicle reverses at high speed into the parking space, then the parking maneuver is faster and more efficient, but the impact with parking stops becomes excessive causing vehicle body tilting and poor riding experience
Solution Approach 1:
The system dynamically adjusts the reversing speed based on real-time conditions, including the distance to parking stops and vehicle position. Rather than maintaining a constant high speed for efficiency, the speed is continuously optimized to balance parking efficiency with impact reduction, allowing faster reversal when safe and slower speeds when approaching parking stops.
Solution Approach 2:
The control system changes the speed parameter of the vehicle during the reversing process. By adjusting the reversing speed from higher initial values to lower values as the vehicle approaches the parking stops, the system maintains overall parking efficiency while reducing impact at critical moments.

AI summary
The invention provides a vehicle control method and device, a computer storage medium, and a vehicle, which are applied to the technical field of automobiles. The vehicle control method includes: determining, based on first information, second information, and third information, whether a vehicle is performing a reverse parking maneuver; comparing a reversing speed with a predetermined first speed when the vehicle is performing the reverse parking maneuver; and if the reversing speed is higher than the predetermined first speed, outputting a first control signal to adjust the reversing speed such that the reversing speed is not higher than the predetermined first speed, where the first information includes information indicating that the vehicle is in reverse gear, the second information indicates an environment surrounding the vehicle, and the third information indicates that the reversing speed is lower than a predetermined second speed, where the predetermined first speed is lower than the predetermined second speed.
