“…In addition, control of the active suspension [30], active steering [31], etc., have brought high efficiency for ensuring the car's stability when moving. A stabilizer bar also called an anti-roll bar, is another very effective way to prevent a car from rolling [32]. Stabilizer bars are made in many different ways these days.…”

In this article, the author discusses the issue of vehicle roll instability when steering at high speeds. Installing an active stabilizer bar in a car is recommended to prevent it from rolling over and make it more stable when it does. A complex dynamic model is set up to evaluate and analyze vehicle oscillations. Besides, a fuzzy algorithm with three independent inputs is used to control the operation of the active stabilizer bar. This algorithm uses three separate inputs derived from the vehicle's oscillating signals.In addition, the membership function and fuzzy rule are designed to ensure that the quality and efficiency of the system are well-maintained and stable. This is an entirely new method, which is rarely used for complex models of cars. Numerical simulation is carried out in a Simulink environment with many specific cases and situations. According to research findings, the roll angle of the vehicle body increases as the speed increases. This causes a greater change in wheel dynamics force and increases the risk of rollover. If the car is equipped with an active stabilizer bar controlled by the fuzzy algorithm with three inputs, these problems are significantly reduced compared to all other situations. So, when this new algorithm is added to the active stabilizer bar, the car's stability and safety can improve even.

“…41 The typical bar commonly used is called the passive bar. As the name suggests, it can only passively generate force, depending on the change in unsprung mass displacement, according to Nguyen et al 42 However, the response of the mechanical stability bar is not good, so the solution using active stabilizer bars is preferred. There are two main active bars: electronic bars and hydraulic bars.…”

Using stabilizer bars in cars to limit rollover is a necessity applied to many vehicles today. In this article, the author proposes using a new fuzzy method to control the hydraulic stabilizer bars. Previous studies only focused on improving the roll stability of cars, while this article focuses on ensuring both the roll stability and ride comfort of the vehicle, which is considered the new contribution of the article. Vehicle oscillations are described through a complex nonlinear dynamic model. The MATLAB® application performs the simulation with two specific cases, including fish-hook steering and J-turn steering. According to the findings of this research, the roll angle value is significantly reduced when using active stabilizer bars directed by the novel algorithm. In addition, the risk of the rollover was also strongly reduced for both simulations (there are four-speed thresholds used in each case). For the first case, rollover does not occur when the car utilizes active stabilizer bars, even when travelling at v4 = 100 (km/h). In the other case, the rollover occurs only for the Active situation when travelling at a very high speed. In contrast, this phenomenon occurs in the None situation at v1 and the Passive situation at v2. The results found from this work help to evaluate the performance of the fuzzy control algorithm for active stabilizer bars.

“…Some advanced materials are used as an alternative to steel, such as synthetic composites, according to Masture [37]. The force generated by the passive bar can be calculated according to the displacement of the linking point [38] or the unsprung mass displacement [39]. The impact force of mechanical anti-roll bars is relatively small, so it cannot meet the roll stability requirements of the vehicle.…”

“…To improve the system's quality, Nguyen added input to the fuzzy controller, making it a complex algorithm with three inputs [46]. The third input is the value of the unsprung mass displacement or vertical force at the wheel, which is considered in calculating the force of passive anti-roll bars [39]. The fuzzy algorithm presented in [46] suits many steering cases.…”

In this article, the author introduces a new fuzzy control solution to direct active anti-roll bars (hydraulic stabilizer bars) in order to enhance the vehicle’s roll stabilization efficiency. The original fuzzy algorithm designed in this work can satisfy all the roll stability, comfort, and response speed requirements, while previous algorithms could only meet one of these criteria. In addition, a fully dynamic model is established to simulate the vehicle’s roll oscillations instead of only using a simple half-dynamic model combined with the single-track dynamic model. The calculation and simulation processes take place in the Simulink environment. Two cases of steering are used as input to the simulation problem; the car’s speed is gradually increased through three levels. According to results of research, the roll angle and roll index of the car increase as the speed and steering angle increase. The interaction between the road and wheel decreases sharply as the roll angle increases, which can lead to a rollover. In the first case, the rollover occurs only when the car travels at v3 without the stabilizer bar and has a maximum roll angle of 9.81°. In the second case, this occurs for the (None) situation when traveling at speed v1 with a maximum roll angle of 9.52° and for the (Passive) situation when traveling at speed v2 with a peak value of 11.93°. Meanwhile, the vehicle’s stability is still well guaranteed when utilizing active anti-roll bars controlled by an original fuzzy algorithm.
