Virtual Vehicle Drift Control for Continuous Curve Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Virtual vehicles in virtual environments often collide with roadside props when navigating continuous curves, due to their inability to effectively manage steering radius and maintain a drift state, leading to reduced capability in passing through such curves.
Innovation Solution
A virtual vehicle control method that involves displaying a virtual vehicle in a driving state, controlling it to enter a drift state through specific steering and brake operations, allowing the head direction to change and maintain the drift state without interruption, thereby reducing the steering radius and improving passage through continuous curves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the virtual vehicle enters a drift state to reduce steering radius, then the vehicle can quickly pass through curves, but the vehicle easily collides with roadside props when encountering continuous curves
Solution Approach 1:
The patent applies dynamics by making the drift state adjustable and controllable through handbrake operations. The vehicle can dynamically enter, maintain, and exit drift states based on driving conditions, allowing the steering radius to be adaptively reduced while maintaining control for collision avoidance in continuous curves
Solution Approach 2:
The patent changes the friction parameter between tires and ground by activating the handbrake to enter drift state. This parameter change reduces the steering radius and allows the vehicle to quickly pass through curves while the driver can control the duration and intensity of the drift to avoid collisions
2Productivity
If the virtual vehicle maintains drift state through continuous handbrake operation, then the steering radius is reduced, but the complexity of control operations increases
Solution Approach 1:
The patent applies self-service by allowing the vehicle's existing handbrake mechanism to serve the dual purpose of both braking and inducing drift state. The same control component (handbrake) that slows the vehicle also creates the drift condition, eliminating the need for additional specialized controls and reducing overall system complexity

AI summary
This application discloses a virtual vehicle control method performed by a computer device. The method includes: displaying a virtual vehicle in a virtual environment; controlling the virtual vehicle to enter a drift state in response to a first steering operation on a direction control component and a brake operation on a handbrake control component; turning the head direction of the virtual vehicle from a first direction to a second direction in response to a second steering operation on the direction control component; and turning the head direction of the virtual vehicle from the second direction to a third direction in response to the brake operation on the handbrake control component. The drift state of the virtual vehicle is maintained through the brake operation so that a capability of the virtual vehicle to pass through a continuous curve is improved.
