The term “slip angle” has been inconsistently applied in the vehicle dynamics field for some time, even in the presence of a clear definition in the SAE J670 standard defining vehicle dynamic terms. This work proposes the opposite of the Society of Automotive Engineers slip angle convention, not a completely unknown concept in the literature. This proposed slip angle convention is combined with a simple yet novel convention change for axle location. Differences between the conventional model and the new conventions are discussed, and the differences between the proposed convention and SAE J670 are clearly delineated. This work is intended as a reference to be used in the vehicle dynamics community by any researcher wishing to work with a model more intuitively pleasing and widely applicable than the accepted standard. This work does not present a particular new research result. Rather, it provides context on the often confusing choice of vehicle dynamic conventions and suggests a preferable selection.

即使在SAE J670标准中对车辆动力学术语有明确定义的情况下，术语“滑移角”在汽车动力学领域也一直使用不一致。这项工作提出了与汽车工程师协会滑角惯例相反的观点，这在文献中并不是一个完全未知的概念。该提议的滑移角约定与轴位置的简单但新颖的约定更改相结合。讨论了常规模型与新约定之间的差异，并清楚地描述了提议的约定与SAE J670之间的差异。这项工作旨在作为参考，供所有希望使用比接受的标准更直观和更广泛应用的模型的研究人员在车辆动力学社区中使用。这项工作没有提出特别的新研究结果。相反，它提供了有关经常混淆的车辆动态约定选择的上下文，并提出了更可取的选择。
