Vehicle Collision Prediction for Narrow-Space Passage Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles face challenges in smoothly passing through narrow traffic spaces due to limitations in in-lane avoidance or lane change maneuvers, leading to potential collisions.
Innovation Solution
An electronic device predicts potential collisions based on target objects in the vehicle's path and adjusts the vehicle's state to avoid obstacles, using obstacle avoidance instructions and prompt messages to ensure safe passage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If in-lane avoidance or lane change avoidance is used, then the autonomous vehicle can pass smoothly in open spaces, but it cannot pass through narrow traffic spaces
Solution Approach 1:
The patent applies dynamics by making the vehicle's spatial configuration adjustable through folding rearview mirrors and adjusting the sunroof state. The vehicle transitions from a static to a dynamic state, changing its occupied space dimensions adaptively based on the narrow traffic space conditions to enable smooth passage
Solution Approach 2:
The patent changes physical parameters of the vehicle by folding the rearview mirrors to reduce width and adjusting the sunroof to reduce height. These parameter changes allow the vehicle to fit through narrow spaces that would otherwise be impassable with the vehicle in its normal configuration
2Reliability
If the vehicle changes traveling state to avoid collision, then it can pass through narrow space, but it may still collide if the target object is not avoided
Solution Approach 1:
The patent performs preliminary collision prediction by obtaining prediction results before executing traveling state changes. The electronic device predicts whether the vehicle will collide with target objects in both current and target traveling states, allowing proactive adjustment of the traveling state to avoid collisions before they occur
Solution Approach 2:
The patent implements feedback by using collision prediction results to dynamically adjust the vehicle's traveling state. The system continuously monitors the predicted collision risk and adjusts the traveling state accordingly, creating a closed-loop control system that improves both safety and efficiency
3Use of energy by moving object
If the vehicle maintains current traveling state, then it avoids unnecessary state changes, but it collides with target objects in narrow spaces
Solution Approach 1:
The patent performs preliminary collision prediction analysis before executing any traveling state changes. By obtaining prediction results in advance, the system can determine whether state changes are necessary, avoiding unnecessary energy consumption while ensuring collision safety when changes are required

AI summary
Embodiments of this application provide a vehicle control method, a device, and a storage medium. The method includes: obtaining information about a target object in a preset range of a target traveling path and a first predicted channel of a vehicle, where the first predicted channel is continuous space occupied when the vehicle travels on the target traveling path in a current traveling state; obtaining a first prediction result based on the first predicted channel and the information about the target object; and controlling the vehicle to travel in a target traveling state when the first prediction result indicates that the vehicle is to collide with the target object when traveling on the target traveling path in the current traveling state, where space occupied by the vehicle in the target traveling state is less than the space occupied by the vehicle in the current traveling state. In this way, the vehicle smoothly passes through the narrow target traveling path without colliding with the target object.
