Abstract

When dealing with electric vehicles, different powertrain layouts can be exploited. Among them, the most interesting one in terms of vehicle lateral dynamics is represented by the one with independent electric motors: two or four electric motors. This allows torque-vectoring control strategies to be applied for increasing vehicle lateral performance and stability. In this paper, a novel control strategy based on torque-vectoring is used to design a drifting control that helps the driver in controlling the vehicle in such a condition. Drift is a particular cornering condition in which high values of sideslip angle are obtained and maintained during the turn. The controller is applied to a rear-wheel drive race car prototype with two independent electric motors on the rear axle. The controller relies only on lateral acceleration, yaw rate, and vehicle speed measurement. This makes it independent from state estimators, which can affect its performance and robustness.

Abstract

In the digital landscape where blockbuster franchises dominate racing games, one title has quietly built a massive following without marketing budgets, big-name licenses, or complex features. That game is Drift Hunters — a free-to-play drifting simulator that lives inside your browser, yet competes with games many times its size. So how did a humble Unity web game capture the hearts of car enthusiasts, gamers, and content creators around the world? The answer lies in its simplicity, authenticity, and the culture it tapped into — one slide at a time.
