Torque Allocation of Hybrid Electric Trucks for Drivability and Transient Emissions Reduction

This paper aims at investigating powertrain behaviour, especially in transient dynamic responses, using a nonlinear truck vehicle model with parallel hybrid configuration. A power split control was designed to achieve the desired drivability performance, focus on NOx emissions. The controller characterized by high-level model-based logic used elaborate total torque required, and low-level allocation strategy for splitting between engine electric motor. final task enhance based driver requests, goal of reducing—in configuration—transient diesel emissions when compared conventional pure thermal powertrain. Different parameters were investigated assessment terms external input disturbance rejection reduction. investigation performance limited simulation Tip-in manoeuvre, which showed satisfying trade-off
