An Aggregated Dynamic Model of an Electronically Actuated ICE Powertrain

Electronically actuated systems in internal combustion engine (ICE) vehicles provide an opportunity for introducing partial autonomy these vehicles. Controllers total or of vehicle motion necessitate models vehicular characterized by accurate transient and steady-state responses. We consider ICE powertrain with a push belt type continuous variable transmission (CVT) associated double pinion planetary gear set. propose novel model the set as differential-algebraic-equation (DAE) system switching dynamics. extend dynamic torque converter incorporating dynamics clutch it. combine CVT variator kinematics pulley hydraulics develop aggregated model. Further, we construct data-driven CVT’s traction coefficient equilibrium force ratio. To operate CVT, design rule-based controller that makes function at discrete ratios. Furthermore, directional control valve (DCV) to capture flows during transients DCV. existing components study utility proposed models. three case examples realistic scenarios resembling maneuver traffic, stop-and-go motion, reverse examine models’ ability characteristics compare resulting behaviour expected response.
