“…In addition, regarding the control method of torsional vibration of the range extender, early research mainly concerned vibration control during the start and stop processes of the engine (Guo and Wang, 2016, 2017a, 2017b; Guo et al, 2009; Hwang, 2013), as well as engine torque compensation control (Andert et al, 2017; Xiong et al, 2020); however, there has been less research on controlling the typical working process of the range extender.…”

The noise of extended-range electric vehicles is an industry concern, with the range extender providing the main noise source. Suppressing torsional vibration is important for reducing the noise of the range extender. A new combined model of system dynamics, generator control, range extender control, and active vibration control is proposed. The working state and torsional vibration characteristics of the model were analyzed under typical working conditions for the start, idling, stable operation, and stop stages. Under steady-state working conditions, for example, idling and stable operation stages, the torsional vibration of the range extender is mainly related to the excitation torque fluctuation of the engine, and when switching the operation stage (e.g., from idling to stable operation), it is mainly related to sudden changes in the generator and engine torque. An active vibration control model—including active torque composition controllers for engine torque fluctuation and switching the operation mode—is established. The simulation showed that active control effectively improved the torsional vibration and provided a new concept for controlling torsional vibration.

During the deceleration phase of a hybrid electric vehicle (HEV), a moment-of-inertia-driven (MoI-driven) engine start-up process can provide a potential economic benefit because it reduces the energy consumption of the starting device. During this start-up process, it is important to maintain drivability by enabling a quick start-up, low driveline vibration, and fast response to torque demand. The wheel rolling distance control should also be considered. This paper proposes electrical motor (EM) participation in an MoI-driven engine start-up process and studies an adaptive model-based predictive optimization method for the drivability control of P2 parallel hybrid vehicles. Based on a new triple mass-spring-system model, an adaptive model predictive controller (MPC) is designed with EM torque set points, clutch friction torque set points, and engine torque set points as manipulated inputs and engine speed, torsion speed, and wheel rolling distance as the measured outputs. A predicted torque demand is introduced to enhance the torque response performance. By considering the constraints of power source components, an optimization algorithm is developed. A simulation is conducted to verify the control strategy on the HEV powertrain and on vehicle dynamics models. The results show that under the same level of start-up, the torsion speed can be reduced by up to 50% with an improved wheel rolling distance and low torque demand error during a certain deceleration.
