“…Yaw-plane vehicle dynamics and controls are most critical in view of vehicle handling performance and directional stability, where the combined steady-state and transient steering/handling characteristics play the most important roles. A compromise between vehicle handling responsiveness and directional stability exists and should be balanced, where vehicle path, yaw rate and lateral acceleration are assumed to be closely related to responsiveness, while vehicle sideslip angle and roll angle are correlated to stability [58].…”

The background to the development of so-called 'green' or 'low carbon' vehicles continues to be relentlessly rehearsed throughout the literature. Research and development (R&D) into novel powertrainsoften based on electric or hybrid technologyhas been dominating automotive engineering around the world for the first two decades of the twenty-first century. Inevitably, most of the R&D has focused on the powertrain technology and the energy management challenges. However, as new powertrains have started to become commercially available, their effects on other aspects of vehicle performance have become increasingly important. This paper focuses on the review of the integration of new electrified powertrains with the vehicle dynamics and control systems. The integration effects can be discussed in terms of three generic aspects of vehicle motions, namely roll-plane, pitch-plane, and yaw-plane, which however are strongly coupled. Topic on regenerative suspension is further discussed. It quickly becomes clear that this integration poses some interesting future engineering challenges to maintain currently accepted levels of ride, handling and stability performance.

In this paper, the effect of both passive and actively-modified vehicle handling characteristics on minimum time manoeuvring for vehicles with 4-wheel torque vectoring (TV) capability is studied. First, a baseline optimal torque vectoring strategy is sought, independent of any causal control law. An optimal control problem (OCP) is initially formulated considering 4 independent wheel torque inputs, together with the steering angle rate, as the control variables. Using this formulation, the performance benefit using torque vectoring against an electric drive train with a fixed torque distribution, is demonstrated. The sensitivity of TV-controlled manoeuvre time to the passive understeer gradient of the vehicle is then studied. A second formulation of the optimal control problem is introduced where a closed-loop torque vectoring controller is incorporated into the system dynamics of the OCP. This formulation allows the effect of actively modifying a vehicle's handling characteristic via TV on its minimum time cornering performance of the vehicle to be assessed. In particular, the effect of the target understeer gradient as the key tuning parameter of the literature-standard steady-state linear single-track model yaw rate reference is analysed.

“…For example, in the work [11] the measurement noise and process noise covariance matrices are dynamically calculated or recomputed during the filter operation. To improve the algorithm robustness, other methods propose also advancements of the Kalman filter with the nonsensitivity band for control deviations, sensor bias compensation, road bank angle compensation, surface friction estimation, or blending of control terms [12,13].…”

One of the most important challenges for electronic stability control (ESC) systems is the identification and monitoring of tire rolling environment, especially actual tire-road friction parameters. The presented research considers an advanced variant of the ESC system deducing the mentioned factors based on intelligent methods as fuzzy sets. The paper includes: • Overview of key issues in prototyping the algorithms of Electronic Stability Control. • Case study for vehicle model. • Procedures for monitoring of tire rolling environment: theoretical backgrounds, computing methods, fuzzy input and output variables, fuzzy inference systems, interface with ESC algorithm. • Case study for ESC control algorithm. • Examples of simulation using Hardware-in-the-Loop procedures. The proposed approach can be widely used for the nextgeneration of ESC devices having the close integration with Intelligent Transport Systems.
