“…Zeng et al 27 pointed out that the generation and direction of the longitudinal jerk are derived from the change rate of the power source torque and the inertia. Similarly, Ma et al 28 compared the simulation study of the switching from the power input-split to output-split mode by considering or not considering the inertia. Relevant simulations indicated that the motor control strategy based on the inertia compensation could effectively suppress the output shaft torque fluctuation of 66% in contrast with the other.…”

Summary Aiming at the problem of torque coordinated control between motor with high‐frequency response and engine with low‐frequency response of hybrid electric vehicle (HEV) during mode transition process, the mechanism of its coordinated control problem is deeply explored, and the essence of dynamic coordinated control strategy (DCCS) through torque coupling analysis is also revealed, namely, motor torque compensation control. Then a series of domestic and international researches on multi‐power sources coordinated control are systematically summarized from the establishment of electromechanical transmission (EMT) system model, mode switching process analysis, engine‐clutch‐motor coordinated control strategy based on torque estimation and speed feedback tracking, as well as the controller robustness analysis under system parameter perturbation and external disturbance. Finally, the key issues on the rapidity, adaptability, and experiment of torque coordination control which need to be solved in the subsequent researches are pointed out clearly.

“…Zhu et al [9] raised a phased compensation control law based on speed tracking according to the different control stages. Ma et al [10] showed that the motor control strategy based on the inertia compensation could effectively suppress the output shaft torque fluctuation of 66%. Lin et al [11] also studied the effectiveness of the motor torque compensation control strategy in reducing the longitudinal jerk.…”

In order to improve the mode switching stability of a power-split hybrid electric vehicle (HEV), a torque coordinated control strategy based on disturbance observation and compensation is proposed. Aiming at the problem of engine torque disturbances caused by engine modeling error, torque control error, working environment interference and other factors, and vehicle load torque interference caused by changes in vehicle driving conditions, an improved linear extended state observer (ILESO) is designed at first. According to the deviation control principle, the state variable regulation mechanism using the same error term in the traditional linear extended state observer (TLESO) is revised, and improved by adding the corresponding deviation between the state variable and its observed value separately. Then the Lyapunov stability of the error system for the ILESO is proved gradually. On this basis, a torque redistribution algorithm of two motors based on disturbances compensation is put forward. After that, simulation verification and road adaptability analysis are carried out subsequently. The results show that the coordinated control strategy based on ILESO, compared with the TLESO, has higher observation accuracy, and makes the HEV have better vehicle speed tracking stability and mode switching smoothness when the vehicle is subject to the same external disturbance, as well as excellent adaptability under a wide range of road conditions.
