“…Energy-saving measures based on the physical characteristics of hybrid electric vehicles have become a research focus in recent years [1]- [5]. The internal combustion engine (ICE) start-up has an important effect on energy consumption [6] [7]; hence, economical ICE starting methods are worthy of attention. When driving a hybrid vehicle, the ICE may restart frequently.…”

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.

“…In [8,9] an approximate model, called the high-level model is presented by Carl Hedrick and his colleagues. In [10,11], the controllable models of an SI engine were presented in cold start phase, this model was further used to reduce emission and fuel consumption in the cold start phase. These models have an experimental basis, but they have not including the effect of intake and exhaust valve overlapping (VO) on air pollution and volumetric efficiency.…”

We present a controllable model of an internal combustion engine that captures the overlapping of the cylinder valves as a controllable parameter and its effect on engine efficiency and EGR rates. The model parameters have been calibrated for the EF7 engine and validated with experimental data. This model successfully estimates the performance and HC and NOx emissions concentration of the engine under cold start operating condition. A model-based fuzzy-threshold control strategy has been proposed in cold start operating condition. This strategy uses the overlapping angle of the cylinder inlet and outlet valves as an extra degree of freedom in comparison to the regular PID strategy in order to accelerate the warm-up duration the catalyst converter while reduces the exhaust harmful emissions during the warm-up phase. The proposed controller model has been verified in MATLAB Simulink environment and simulation results indicates 8.6% reduction of the start-up time of the catalyst converter and reduction of 3.5%, 8.5% and 7% of HC, NO and fuel consumption respectively during the catalyst warm-up phase.

The carried out modelling of SI engine injection system characteristics in various steady-state conditions has been presented in the article. Also, the two ways of determining injection time have been shown: by means of a virtual model made with the use of software worked out by National Instruments LabVIEW and on the experimental test stand ''Integrated injection-ignition system of the K16 engine".
