Summary
Sudden tire blow-outs compromise vehicle stability. This study introduces a 14 degrees-of-freedom (DOF) model and an integrated control system to enhance vehicle stability during such emergencies.
Area of Science:
- Automotive Engineering
- Control Systems Engineering
- Vehicle Dynamics
Background:
- Sudden tire blow-outs significantly degrade vehicle stability, leading to accidents.
- Existing research lacks comprehensive 3D vehicle dynamics modeling and stability control for tire blow-outs.
Purpose of the Study:
- To develop a comprehensive 14 degrees-of-freedom (DOF) vehicle dynamics model for post-tire blow-out scenarios.
- To present an integrated control framework for simultaneous yaw and roll plane stability control.
Main Methods:
- Proposed a 14 DOF vehicle dynamics model to simulate yaw and roll plane behavior after a tire blow-out.
- Developed an integrated control framework comprising a vehicle state predictor, control mode supervisor, and a model predictive controller (MPC).
- Utilized MPC to manage individual actuators for combined yaw and roll plane stability control based on predicted vehicle states.
Main Results:
- The proposed 14 DOF model accurately describes vehicle dynamics post-tire blow-out.
- The integrated control framework effectively manages vehicle stability in both yaw and roll planes.
- Simulation tests confirmed the efficacy of the proposed stability control strategy.
Conclusions:
- The developed 14 DOF model and integrated control strategy offer a robust solution for enhancing vehicle stability after a tire blow-out.
- This research addresses a critical gap in vehicle safety by providing advanced control mechanisms for tire failure events.

01:17Rolling Resistance: Problem Solving
494
Rolling resistance, also known as rolling friction, is the force that resists the motion of a rolling object, such as a wheel, tire, or ball, when it moves over a surface. It is caused by the deformation of the object and the surface in contact with each other, as well as other factors like internal friction, hysteresis, and energy losses within the materials. Rolling resistance opposes the object's motion, requiring additional energy to overcome it and maintain movement. In practical...

The transfer function is a fundamental concept representing the ratio of two polynomials. The numerator and denominator encapsulate the system's dynamics. The zeros and poles of this transfer function are critical in determining the system's behavior and stability.
Simple poles are unique roots of the denominator polynomial. Each simple pole corresponds to a distinct solution to the system's characteristic equation, typically resulting in exponential decay terms in the system's...

A three-dimensional force system refers to a scenario in which three forces act simultaneously in three different directions. This type of problem is commonly encountered in physics and engineering, where it is necessary to calculate the resultant force on the system, which can then be used to predict or analyze the behavior of the object or structure under consideration.

When a solid cylinder rolls steadily on a rigid surface, the normal force applied by the surface on the cylinder is perpendicular to the tangent at the contact point. However, since no materials are entirely rigid, the surface's reaction to the cylinder involves a range of normal pressures.
For instance, imagine a hard cylinder rolling on a comparatively soft surface. The cylinder's weight compresses the surface beneath it. As the cylinder moves, the material in front of it slows down...
