Abstract
This article presents a new dynamic motion stabilization approach to front-wheel drive in-wheel motor electric vehicles. The approach includes functions such as traction control system, electronic differential system, and electronic stability control. The presented electric vehicle was endowed with anti-skid performance in longitudinal accelerated start; smooth turning with less tire scrubbing; and safe driving experience in two-dimensional steering. The analysis of the presented system is given in numerical derivations. For practical verifications, this article employed a hands-on electric vehicle named Corsa-electric vehicle to carry out the tests. The presented approach contains an integrated scheme which can achieve the mentioned functions in a single microprocessor. The experimental results demonstrated the effectiveness and feasibility of the presented methodology.

Summary
Due to the demands on pollution-free and quieter driving experiences, the electric vehicles (EVs) have become a popular investigation topic. From the viewpoint of drive-train (or say power-train), as depicted, EVs can be classified into two types as follows: 1. The drive-train of the first type EV is the same as the conventional internal combustion engine vehicles. Mechanisms such as gearbox, clutch, differential, and shaft are employed for power distribution. The second type is famous as the in-wheel motor EVs. The in-wheel motor EVs are powered by independently equipped motors to drive each wheel.[1] For urban sedans, there are always two driving styles formed, that is, two-wheel drive (frontwheel drive or rear-wheel drive) or four-wheel drive. No matter what kind of the drive styles, due to the lack of mechanism supporting, the power decentralized systems require more advanced technologies to ensure the dynamic stability of the steering.
