Summary: This paper presents a design for a dual clutch transmission (DCT) driveline torque observer aimed at improving estimation performance. The observer's performance is increased by accurately modeling the driveline and creating a robust observer. The paper proposes a lumped driveline efficiency parameter to increase the model's accuracy, estimated using driving data through a recursive least square estimation algorithm. A reduced order observer is also proposed, along with a robust design using frequency domain analysis. Simulation and testbench experiments verified the performance of the proposed algorithm and observer.

Summary: This study establishes a control-oriented model and proposes an extended-state-observer-based compensator to suppress driveline oscillations in hybrid electric vehicles (HEVs). By designing an extended state observer, the unmeasurable load torque can be estimated accurately. Simulation and engine-in-loop experiments show that this control scheme substantially reduces driveline oscillation.

Summary: A theoretical dynamic model of vehicular driveline is proposed to study the mechanism of low frequency interior booms within a low engine speed range, demonstrating the torsional-lateral-longitude coupling effects of propeller shafts and integral rear axle assembly. Analyses of critical engine speed and dynamic response on a rear-wheel-drive vehicle show that the model achieves a balance between accuracy and efficiency, capable of identifying the contributions of Hooke's joints for boom problems.

Summary: This paper investigates the driveline oscillation of a series-parallel hybrid vehicle on launch condition. An analytic model considering nonlinear backlash disturbance is established and a feedforward-feedback hybrid control strategy is proposed to suppress driveline vibration. Numerical simulation results demonstrate the robustness of the control strategy in attenuating driveline oscillation under deteriorating nonlinear backlash conditions.
