Vehicle Wheel Control for Collision Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle collision countermeasures primarily rely on passive responses such as collision warning sounds and braking controls, which may not adequately ensure driving stability and safety during potential collisions with peripheral objects.
Innovation Solution
A method for actively controlling vehicle wheels by estimating the possibility of collision using relative speed and distance, adjusting camber, toe, and steering to minimize the impact of collisions and maintain driving stability, involving sensors and a controller to detect objects and calculate collision estimation indices.

Engineering Contradiction Analysis
1Reliability
If passive collision countermeasures (warning sound, braking control, seat belt control) are used, then collision warning is provided, but driving stability and safety during actual collision cannot be ensured
Solution Approach 1:
The controller performs preliminary actions by estimating collision possibility and adjusting wheel parameters (camber, toe, steering) before actual collision occurs. This proactive adjustment ensures driving stability during collision without requiring complex active structural changes
Solution Approach 2:
The invention changes wheel parameters (camber angle, toe angle, steering angle) based on estimated collision scenarios. By adjusting these parameters in advance, the system improves driving stability during collision while avoiding the need for complex mechanical reinforcement structures
2Reliability
If wheel parameters are adjusted based on collision estimation, then driving stability during collision is improved, but control system complexity increases
Solution Approach 1:
The controller estimates collision possibility and adjusts wheel parameters in advance based on sensor data. This preliminary control preparation improves safety during actual collision while maintaining a relatively simple controller architecture that processes sensor inputs and outputs control signals
Solution Approach 2:
The system uses sensor feedback (detecting objects in peripheral regions) to continuously monitor collision risk and dynamically adjust wheel parameters. This feedback mechanism improves collision safety while keeping the control system manageable through closed-loop control based on real-time sensor data
3Ease of manufacture
If conventional passive collision response is used, then implementation is simple, but sufficient driving stability and safety cannot be provided
Solution Approach 1:
The system implements preliminary wheel parameter adjustments based on collision estimation, providing active collision response rather than passive reaction. This approach maintains implementation simplicity through software-based control while significantly improving driving stability during collision
Solution Approach 2:
The invention dynamically adjusts wheel parameters (camber, toe, steering) based on real-time collision estimation rather than using fixed passive structures. This dynamic control provides sufficient driving stability during collision while keeping the system relatively simple through electronic control rather than mechanical complexity

AI summary
A vehicle and a method for controlling the same are provided. In particular, the wheels of the vehicle wheels are controlled based on a possibility of collision between the vehicle and an object located in a peripheral region of the vehicle to minimize influence caused by the collision while simultaneously ensuring driving safety. The method includes estimating whether there is a high possibility of collision between the vehicle and the detected object. When the high possibility of collision between the vehicle and the object is estimated the wheels of the vehicle are operated based on a situation of the estimated collision to ensure driving stability of the vehicle during an actual collision between the vehicle and the object.
