This article describes the features of the use of electric and hybrid drive in transport vehicles. Considers the limitations of using all-electric vehicles. The necessity of developing a hybrid drive for heavy-duty vehicles is substantiated. The basic formulas for calculating the power of an electric drive hybrid vehicle are resented. A comparison is given of the results of the calculation of the main dynamic characteristics of the transport vehicle with various types of power unit. To which include: acceleration time, acceleration path and the average speed of movement. In conclusion, the most efficient type of drive is determined.

Transmission mounted electric drive type hybrid electric vehicles (HEVs) engage/disengage an engine clutch when EV↔HEV mode transitions occur. If this engine clutch is not adequately engaged or disengaged, driving power is not transmitted correctly. Therefore, it is required to verify whether engine clutch engagement/disengagement operates normally in the vehicle development process. This paper studied machine learning-based methods for detecting anomalies in the engine clutch engagement/disengagement process. We trained the various models based on multi-layer perceptron (MLP), long short-term memory (LSTM), convolutional neural network (CNN), and one-class support vector machine (one-class SVM) with the actual vehicle test data and compared their results. The test results showed the one-class SVM-based models have the highest anomaly detection performance. Additionally, we found that configuring the training architecture to determine normal/anomaly by data instance and conducting one-class classification is proper for detecting anomalies in the target data.
