Improving the method of regenerative braking of a car with a start-stop system by installing an additional generator is offered. An option of the optimal control of the brake torque of an additional generator is offered. The regenerative braking under consideration required an appropriate method of calculation. This technique makes possible to obtain the dependence of the braking moment on the angular velocity of the generator in various modes, the dependence of the allowable maximum generator power on the speed and load, the dependence of efficiency and the braking moment on the speed. Redistribution of energy generated by an additional generator for charging the battery and heating the engine coolant has been introduced. The brake torque of the electric machine G290 is calculated in the mode of regenerative braking. The obtained results are of practical importance for the transport industry. Calculated N at which the current 150 А is reached. According to factory data the ultimate current is reached at 1450 rpm (discrepancy of less than 3%). So, there is a good coincidence of calculated data. This method does not require a great number of experimental points. The obtained results are of practical importance for the transport industry.

“…Compared to AHS, China hybrid system (CHS) only uses a one-way clutch and one brake, which makes the system more simple and easy to control. 15 Due to the high cost of wet or dry clutch, two dog-tooth clutches are used in infinitely variable transmission (IVT) of Renault. 16 Ford hybrid system (FHS) replaces the planetary gear with spur gear to reduce manufacturing cost.…”

Considering the energy consumption and specific performance requirements of mining trucks, a novel uninterrupted multi-speed transmission is proposed in this paper, which is composed of a power-split device, and a three-speed lay-shaft transmission with a traction motor. The power-split device is adapted to enhance the efficiency of the engine by adjusting the gear ratio continuously. The three-speed lay-shaft transmission is designed based on the efficiency map of traction motor to guarantee the drivability. The combination of the power-split device and three-speed lay-shaft transmission can realize uninterrupted gear shifting with the proposed shift strategy, which benefits from the proposed adjunct function by adequately compensating the torque hole. The detailed dynamic models of the system are built to verify the effectiveness of the proposed shift strategy. To evaluate the maximum fuel efficiency that the proposed uninterrupted multi-speed transmission could achieve, dynamic programming is implemented as the baseline. Due to the “dimension curse” of dynamic programming, a real-time control strategy is designed, which can significantly improve the computing efficiency. The simulation results demonstrate that the proposed uninterrupted multi-speed transmission with dynamic programming and real-time control strategy can improve fuel efficiency by 11.63% and 8.51% compared with conventional automated manual transmission system, respectively.

Abstract. The natural mode shape of planetary gear train is closely related to vibration and noise. It is valuable to study installation constraints of the planetary transmission, which is very important in the theoretical and engineering. A new method was proposed to study the influence of the planet carrier's different constraints on the planetary gear train's inherent vibration mode. The supporting stiffness of the planetary gear and the center member were considered respectively in the dynamic model of planetary gear train. The planet carrier constraint way simulation was realized through the support stiffness of different combination. A dynamic model with considering the planet carrier constraints was built to study the influence of different installation methods of the carrier on the natural vibration mode. The research indicates that the different installation way has a significant effect on the inherent vibration mode of planetary gear train.
