Predictive Control Applied to Antilock Braking Systems of Heavy Vehicles on Deformable Terrain

Antilock braking systems (ABS) are critical to ensuring vehicle safety, particularly in challenging off-road environments where the braking dynamics is highly complex. This study focuses on the development of an advanced ABS controller for heavy off-road vehicles to improve operational safety and reliability. For this purpose, a Model-based Predictive Control (MPC) is proposed. The predictive capabilities of MPC, which optimize control actions based on system dynamics and constraints, are highlighted as a key aspect of this approach. The controlled system is modeled and simulated using a quarter-car model and a deformable ground model, providing a realistic representation of off-road conditions. Comparative simulations are conducted to evaluate the performance of both controllers, focusing on their effectiveness in maintaining stability and improving braking efficiency.
