“…In this regard, most hybridization kits are obtained by integrated design of the Dual Clutch Transmissions (DCT) and the electric machine to obtain a Hybrid Dual Clutch Transmissions (HDT). The choice of the DCT as transmission is largely driven by the fact that they have high efficiency, simple construction, lower inertia in case of the adoption of wet clutches and smooth gear shifting [9,10]. Furthermore, DCT can allow power-on gear shifting.…”

“…From the vehicle drivability and Noise, Vibration, and Harshness (NVH) point of view, the presence of two excitation sources (ICE and EM) affects the behavior of the powertrain during transient operating modes (frequent changes from electric to conventional or hybrid modes) [10,15,16]. On the other hand, the presence of the EM gives the possibility to attenuate the vibration in the driveline [15][16][17] and improve the gear shifting process [18].…”

“…The torsional behavior of the DCT influences the comfort of the vehicle. Therefore, several works are addressed to study the clutch actuation control with numerical simulations and their experimental validation [10,[22][23][24]. These actuation strategies help to achieve higher comfort levels during the operation mode change.…”

Recent studies show that hybrid powertrains with dual clutch transmission are becoming more common. This is mainly influenced by the fact that they have higher efficiency, allow power-on shifting, and are more compact. However, the electric motor attached to the primary shaft of the transmission might represent some critical issues in statics and dynamics due to additional torque, inertia, and working irregularities. This paper aims to investigate the influence of the electric motor integration in the transmission on the reliability of the overall system. The focus is on the investigation of potential over stresses of the ICE bearings due to the bending of the gearbox primary shaft. To achieve the aim, the static and the rotor dynamic analysis of the inner and outer primary shafts is performed. The numerical analyses show the potential critical issues that can arise from the excessive manufacturing and assembling tolerances, the interaction of the e-machine torque irregularities and inertia with the bending dynamics of the primary shafts.

“…Vehicle speed control in related works was based on environment perception [ 23 ], road conditions [ 24 ], and driver state detection [ 25 ]. A gear shift method for the dual clutch transmission (DCT) was proposed for the speed control of automotive motors [ 26 ]. However, road traffic accidents are avoidable, and Sub-Saharan African countries lack adequate methods of reporting the tangible and intangible costs of road accidents.…”

Road accidents represent the greatest public health burden in the world. Road traffic accidents have been on the rise in Rwanda for several years. Speed has been identified as a core factor in these road accidents. Therefore, understanding road accidents caused by excessive speeding is critical for road safety planning. In this paper, input and out pulse width modulation (PWM) was used to command the metal–oxide–semiconductor field-effect transistor (MOSFET) controller which supplied voltage to the motor. A structural speed control and Internet of Things (IoT)-based online monitoring system was developed to monitor vehicle data in a continuous manner. Two modeling techniques, multiple linear regression (MLR) and random forest (RF) models, were evaluated to find the best model to estimate the required voltage to be supplied to the motors in a particular zone. The built models were evaluated based upon the coefficient of determination R2. The RF performs better than the MLR as it reveals a higher R2 value and it is found to be 98.8%. Based on the results, the proposed method was proven to significantly reduce the supplied voltage to the motor and consequently increase safety.

“…The development of an engine start control method for P2 hybrid vehicles is considered in [17], where the pure electric motor switching to pure ICE mode is considered to prevent the driving torque variation at the time of the engine start. Optimal speed regulation control of hybrid DCT in the shift process is considered in [18] to shorten the torque interruption and reduce the wear of the synchronizer. Finally, the authors of [19] present the optimization of DCT for an axle-split HEV to minimize the fuel consumption.…”

Automatic clutch engagement control is essential for all kinds of vehicle power transmissions. The controllers for vehicle power transmissions may include model-based or model-free approaches and must provide high transmission efficiency, fast engagement and low jerk. Most vehicle automatic transmissions are using torque converters with transmission efficiencies up to 96%. This paper presents the use of fuzzy logic control for a dry clutch in parallel hybrid electric vehicles. This controller can minimize the loss of power transmission since it can offer a higher transmission efficiency, up to 99%, with faster engagement, lower jerk and, thus, higher driving comfortability with lower cost. Fuzzy logic control is one of the model-free schemes. It can be combined with AI algorithms, neuro networks and virtual reality technologies in future development. Fuzzy logic control can avoid the complex modelling while maintaining the system’s high stability amid uncertainties and imprecise information. Experiments show that fuzzy logic can reduce the clutch slip and vibration. The new system provides 2% faster engagement speed than the torque converter and eliminates 70% of noise and vibration less than the manual transmission clutch.
