“…Another emerging development is the integrated starter-alternator [10], in which all or part of the electric drive in a hybrid is closely coupled to the engine. Still others include opportunities when two separate drive motors are used, opportunities to incorporate flywheels, and even ways to use electric machines to counteract torque pulses from the engine [11].…”

-Electric automobiles are clean, efficient, and powerful but are limited in range. Hybrid designs seek to enhance range through the use of liquid fuel. The energy, force, and power needs of a typical car are reviewed. The relationship to fuel cells as energy sources is discussed. Opportunities in the electrical arena, the mechanical arena, and the fuel cell arena are presented. Two commercial hybrid vehicle examples are presented. The convergence of developments in these areas will dominate hybrid designs as commercial production continues to ramp up.

“…To facilitate the torque coordination control problem, early research works neglected the clutch dynamic characteristic, which is a crucial factor to the mode transition performance. The torque compensation control strategy using the fast response ability of the motor was an early torque coordination control method [4,5]. The engine torque was estimated online, and the motor's fast response characteristic was used to compensate the output torque lag of the engine to decrease the total driving torque fluctuation of the mode transition process, which could thus improve the comfortability.…”

Data-Driven Predictive Torque Coordination Control during Mode Transition Process of Hybrid Electric Vehicles

Torque coordination control significantly affects the mode transition quality during the mode transition dynamic process of hybrid electric vehicles (HEV). Most of the existing torque coordination control methods are based on the mechanism model, whose control effect heavily depends on the modeling accuracy of the HEV powertrain. However, the powertrain structure is so complex, that it is difficult to establish its precise mechanism model. In this paper, a torque coordination control strategy using the data-driven predictive control (DDPC) technique is proposed to overcome the shortcomings of mechanism model-based control methods for a clutch-enabled HEV. The proposed control strategy is only based on the measured input-output data in the HEV powertrain, and no mechanism model is needed. The conflicting control requirements of comfortability and economy are included in the cost function. The actual physical constraints of actuators are also explicitly taken into account in the solving process of the data-driven predictive controller. The co-simulation results in Cruise and Simulink validate the effectiveness of the proposed control strategy and demonstrate that the DDPC method can achieve less vehicle jerk, faster mode transition and smaller clutch frictional losses compared with the traditional model predictive control (MPC) method.

“…HEVs, in addition to the conventional internal combustion engine (ICE), are equipped with one or more electrical machines and a battery as energy storage unit (Kemper et al, 2004;Davis and Lorenz, 2003). By utilising the specific advantages of two power sources, hybrid vehicles can adopt various driving modes under the vehicle driving cycle to improve fuel economy and reduce emissions.…”

This paper presents the coordinated control strategies for a full hybrid vehicle with single motor during mode changes. The mode changes between various driving modes are firstly divided into three types according to the similar characteristics of mode transitions. For the first type of mode change, a coordinated control strategy expressed as the combination of clutch pressure fuzzy control and motor torque compensation is proposed. For the second type of mode change, a coordination control strategy of motor speed closed-loop control and clutch pressure control is developed. The coordinated control strategy expressed as the engine throttle opening rate control and motor torque compensation is adopted for the third type of mode change. Performance of these proposed control strategies is validated by experimental tests based on the test bench of the full hybrid drivetrain. The results show a remarkable improvement in drivability of the full hybrid vehicle during mode changes.Keywords: FHEV; full hybrid electric vehicle; mode change; coordinated control; drivability.Reference to this paper should be made as follows: Du, B., Qin, D. and Yang, Y.
