Robust Lateral Trajectory Tracking of Intelligent Vehicles by Using Fuzzy Adaptive Dynamic Model Predictive Control

10-10-02-0009

12/03/2025

To further improve the smoothness and robustness of lateral trajectory tracking for intelligent vehicles under complex operating conditions, this study proposes and experimentally validates a fuzzy adaptive dynamic model predictive control (FADMPC) strategy on the basis of model predictive control (MPC) framework. Thereinto, a three-degrees-of-freedom vehicle dynamics model serves as the predictive model, and a recursive least-squares algorithm with a forgetting factor is used to estimate tire cornering stiffness, thereby improving model fidelity. A whale optimization algorithm (WOA)–based adaptive horizon scheduler is devised to address the sensitivity of the prediction horizon to vehicle speed and road friction, and a fuzzy regulator adjusts the weight on the lateral displacement error in the objective function in real time. Hardware-in-the-loop tests on jointed and split-road surfaces show that compared with adaptive dynamic MPC, traditional MPC, and linear quadratic regulator, the

Lumped Parameter Thermal Network for Automotive Components: Modeling, Simulation, System Identification, and Parameter Estimation

2025-01-5078

11/28/2025

This research paper proposes a framework based on lumped parameter thermal networks (LPTN) to understand the system behavior of thermally stressed component spaces in automotive vehicles. LPTNs offer an energy-based, low-degree-of-freedom model that can represent arbitrary thermal systems inside automotive vehicles. The time response of these low-order models can be calculated using standard ordinary differential equation solvers. The paper showcases the modeling of LPTNs and the calculation of their time response by using an electronic control unit (ECU) of a BMW 7 series. The use of LPTNs instead of exponential functions reduced the MAE in this example by 60.5%. Furthermore, a system identification approach for experimental temperature curves has been developed and implemented. System identification aims to mathematically model system behavior and predict system output. This paper compares least-square estimation (LSE) with constrained minimization (CM), where CM has a higher MAE by

Impinging Shockwave/Boundary Layer Interaction–Induced Separation Mitigation Using Passive Control

01-18-03-0014

11/28/2025

A passive control device to mitigate shock-induced separation in a generic supersonic inlet model is computationally studied. The simulations were based on the Favre-averaged Navier–Stokes equations with the Spalart–Allmaras (SA) turbulence model. The shockwave was generated by an 8° turn supersonic inlet. The Mach number in the inlet was varied between 2.1 and 2.46. The baseline shockwave/boundary layer interaction (SBLI) simulation results compare favorably with experimental data. The passive device, in the form of a splitter plate, eliminates both the separation and flow unsteadiness. The splitter plate causes reduction in the total pressure of the boundary layer at the exit of the inlet due to increased skin friction on the floor and due to wake of the plate.
