In vehicle dynamics, slip angle [1] or sideslip angle [2] is the angle between the direction in which a wheel is pointing and the direction in which it is actually traveling (i.e., the angle between the forward velocity vector and the vector sum of wheel forward velocity and lateral velocity , as defined in the image to the right).

In (automotive) vehicle dynamics, slip is the relative motion between a tire and the road surface it is moving on. This slip can be generated either by the tire 's rotational speed being greater or less than the free-rolling speed (usually described as percent slip), or by the tire 's plane of rotation being at an angle to its direction of ...

Oct 6, 2009 · Essentially, a sideslip result of +0.6mm means your vehicle will travel 0.6mm to the right over a distance (I believe it's 1m in your case) even if the wheels are maintained directly straight. So, with a sideslip result of +0.6mm, over a distance of 1km, your car will "slip" rightwards 600mm, or 60cm, or 0.6m.

This paper proposes a novel methodology to estimate the side-slip angle which is used as an index of vehicle stability. A side-slip angle observer is designed using the bicycle model and the kinematic model.

Mar 12, 2021 · Vehicle sideslip angle is a major indicator of dynamics stability for ground vehicles; but it is immeasurable with commercially-available sensors. Sideslip angle estimation has been the focus of intensive research in past decades, resulting in a rich library of related literature.

Vehicle sideslip angle (VSA) estimation has been a big challenge since the introduction of the very first on-board active systems controlling vehicle stability, such as the electronic stability control (ESC, also known as ESP) in the early 1990s [1].

The vehicle side-slip angle is the angle between the vehicle longitudinal direction and the traveling direction of the vehicle center of gravity, i.e., the tangent line of the circular path. From: Vehicle Handling Dynamics, 2009

Accurate information about the side slip angles of vehicle and tires is critical in controlling vehicle motion in the yaw plane using active chassis systems, such as brake-based Electronic Stability Control (ESC) systems and active front or rear steering systems.

Oct 1, 2017 · From the vehicle stability standpoint, the most important states are sideslip angle, i.e. the angle between the vehicle longitudinal axis and the direction of the vehicle velocity, and the sideslip rate. These are used to determine the control action, re-schedule the parameters of the control architecture or re-establish the vehicle stability.

Jul 1, 2017 · Measuring sideslip angle is costly; in most cases, in most case estimation is a preferred choice. Most estimation solutions are based on dynamical models of the car. To properly work, these solutions need to also estimate the road friction. This increases their complexity and affects their robustness.
