“…The control algorithm is based on the augmentation of the reference trajectories, resulting into a homogeneous TPBVP (two-point boundary-value problem). Moreover, a control strategy for an H-DCT is presented in Zhao et al 19 : The characteristics of a robust H ∞ controller are exploited to complete the speed synchronization of the internal combustion engine (ICE) and the clutch driven plate.…”

This article describes gearshift control strategies developed for a series-parallel hybrid electric vehicle architecture in which an electric machine is connected to the output of the transmission, thus obtaining torque filling capabilities during gearshifts. Two transmission systems are analyzed: hybrid automated manual transmission and hybrid dual-clutch transmission. The article focuses on the gearshift control strategies for the two transmission, splitting each gearshift into several phases. The objectives of each control phase, the equations for computing the set points for powertrain actuators, and the conditions that determine the passage from one shifting phase to the next are reported. Moreover, nonlinear dynamic models are described and used to verify through simulation the effectiveness of the controllers. Promising results, in terms of vehicle dynamic performance, are obtained for both transmission systems.

“…5 In the conventional DCT (and also AT) systems, a rapid increase or decrease of the internal combustion engine (ICE) torque is required to perform smooth downshifts or upshifts, respectively. [6][7][8] The effectiveness of such a control strategy is often limited by the lack of quick and precise engine torque control. In the powertrain equipped with a hybrid transmission, the MG machine, characterized by a fast and accurate torque control, 8 can be involved in the shifting process, which can significantly improve the shift quality in terms of reduction of the vehicle jerk, shift time and clutch energy loss/wear.…”

In order to meet ever demanding requirements on powertrain efficiency and performance improvement, new concepts of automatic transmissions have been introduced recently, including electrified conventional transmissions. A representative example of electrified transmission system is a hybrid dual clutch transmission. The paper presents an optimisation-based comparative analysis of gear shift processes of different hybrid dual clutch transmission configurations and the conventional dual clutch transmission. The paper first outlines a control-oriented mathematical model of a dual clutch transmission/hybrid dual clutch transmission-based powertrain and describes the basic dual clutch transmission gear shift characteristics. The emphasis is then on hybrid dual clutch transmission systems, including overview of most common hybrid dual clutch transmission configurations, bond graph modelling and analysis, and control trajectory optimisation. The bond graph analysis illustrates the possibilities of improving the transmission shift performance by utilising the incorporated electric motor. The analysis findings are then quantitatively illustrated by optimisation results, which point out that a proper electric motor action results in significant improvement of shift quality.

“…[13][14][15] A robust H 1 controller was designed to ensure speed synchronization for dry dual-clutch transmission equipped in a hybrid car. 16 A real-time estimation of transmitted torque on each clutch was proposed for robust control of the dual clutch transmission. 17 Although these control methods show some advantages over the PID controller to offer a better shift quality, improved shift control is still desired for the following two reasons.…”

Clutch slip control of the inertia phase during the clutch-to-clutch shift process is the key to ensure good drive quality in automated transmissions. Addressing the problem of unpleasant driveline jerk and clutch overwear, a novel control scheme consisting of a linear quadratic controller and two compensators is proposed. The compensators are designed to deal with the challenges involving the disturbances and discontinuity in the drivetrain torque during the inertia phase. Compared to the conventional proportional–integral–derivative and classical linear quadratic approaches, the proposed control scheme demonstrates a significant better shift performance in terms of the slipping tracking error and jerk level during shift. The influences of various reference inputs and disturbances are investigated, where the proposed control scheme shows advantages. The proposed control scheme can be adaptable to various engine torque and vehicle load torque with improved control robustness.
