SIMULINK-Based Magic Formula Tire Model (Pac2002) Implementation

The SIMULINK-based Magic Formula tire model (Pac2002) discussed in this document serves as a critical component that can be directly interfaced with other vehicle dynamics modules. This model implements Pacejka's Magic Formula algorithm to simulate tire behavior through nonlinear equations that calculate longitudinal, lateral, and self-aligning torque forces based on slip ratios, slip angles, and camber angles. Its primary purpose is to provide accurate dynamic analysis and prediction capabilities by replicating real-world tire characteristics. The implementation includes configurable parameters for tire stiffness, shape factors, and peak coefficients, allowing customization for different tire specifications. Through S-function blocks or masked subsystems, the model processes input signals like wheel loads and steering angles to generate realistic force outputs. This enhanced simulation approach enables better understanding of vehicle performance and handling characteristics, facilitating design optimization and driving experience improvements. Additionally, the model supports testing various vehicle control algorithms and driving strategies through its modular interface, contributing to enhanced vehicle safety and performance. By integrating this tire model with other dynamics modules, engineers gain comprehensive vehicle analysis capabilities including stability assessment, maneuverability prediction, and system-level performance validation. The modular architecture allows for co-simulation with braking systems, suspension models, and powertrain components through standardized signal buses or physical connection ports.
