“…However, by using the estimated signal instead of the actual lateral acceleration, the phase delay in the ARC system due to the slow hydraulic dynamics can be reduced considerably. This idea is similar to the previous research (Tang, 2008) although the equations for finding the lateral acceleration estimation are different. The performance of the lateral acceleration estimator was validated in the actual vehicle test and is given in Chapter 5.…”

“…Although they demonstrated robust ARC performance in various parameter varying conditions, their results were based only upon a simple 3 DOF vehicle model without any actuator dynamics. Tang (2008) developed an anti-roll control logic for a linear type hydraulic actuator installed in the extended arm of the lateral bar. Covered in this paper are several valuable aspects that need to be addressed before any ARC system is introduced commercially, including logics against rollrock surface response and lift-off oversteer.…”

Developed in this research is a control logic for the ARC (Active Roll Control) system that uses rotary-type hydraulic stabilizer actuators at the front and rear axles. The hydraulic components of the system were modeled in detail using AMESim, and a driving logic for the hydraulic circuit was constructed based upon the model. The performance of the driving logic was evaluated on a test bench, and it demonstrated good pressure tracking capability. The control logic was then designed with the target of reducing the roll motion of the vehicle during cornering. The control logic consists of two parts: a feedforward controller that generates anti-roll moments in response to the centrifugal force, and a feedback controller that generates anti-roll moments in order to make the roll angle to follow its target value. The developed ARC logic was evaluated on a test vehicle under various driving conditions including a slowly accelerated circular motion and a sinusoidal steering. Through the test, the ARC system demonstrated successful reduction of the roll motion under all conditions, and any discomfort due to the control delay was not observed even at a fast steering maneuver.

“…Untripped rollovers account for less than 5% of rolled passenger vehicles in single-vehicle crashes, which often occur during high-speed collision avoidance manoeuvres [1]. Furthermore, rollovers account for nearly 33% of all deaths from sport utility vehicle (SUV), which, being popular in recent years, is considered to be easier to encounter rollover accident than other kinds of passenger vehicles for its higher gravity center and a lower rollover threshold [2][3][4]. Hence, it is necessary to design a rollover prevention controller.…”

This paper proposes the integrated controller of the yaw and rollover stability controls based on the prediction model. A nonlinear 3-DoF vehicle model with a piecewise linearization tire model is built up as the rollover predictive model, and its accuracy is verified by vehicle tests. A yaw stability controller and a rollover stability controller are proposed, respectively. Then coordinated control strategy is investigated for the integration of vehicle yaw and roll stability controls. The additional yaw torque and braking torque of each wheel are calculated. The unified command of valves is sent combined with ABS control algorithm. Virtual tests in CarSim are carried out, including slalom condition and double-lane change condition. Results indicate that the coordinated control algorithm improves vehicle yaw and roll stability effectively.

This paper investigates Stability and maneuverability of Personal Mobility Vehicle (PMV). The purpose of PMV is to provide mobility in city centers. Suspension design concept of PMV is based on accommodating different road scenarios. Non conventional suspension mechanism is adopted to conform stability and handling. Analyses are performed on simple full scale vehicle model to validate the stability of the vehicle. Road scenarios are realized by modeling different terrain profiles. Multi-body analysis techniques are used to obtain the suspension parameters. The vehicle is analyzed on different roads to observe the effect of inertia on system dynamics. The results present the angular velocity, angular acceleration, roll, yaw and pitch variations about center of gravity of the vehicle. © 2012 IEEE
