The invention relates to a double-motor driving device with a parking brake of an electric forklift. The double-motor driving device comprises a speed reducer and driving motors, wherein the speed reducer comprises an output shaft, a left input shaft and a right input shaft which are parallel to each other. An output gear is arranged on the output shaft, a left input gear is arranged on the left input shaft, a right input gear is arranged on the right input shaft, and the left input gear and the right input gear are both meshed with the output gear constantly. The extending-out end of the output shaft is connected with the input shaft of the speed reducer through a transmission shaft, the extending-out end of the left input shaft is provided with a braking drum and the parking brake respectively, the other end of the left input shaft is connected with a left driving motor through a spline, the right input shaft is connected with a right driving motor through a spline, and the left driving motor and the right driving motor are arranged side by side. According to the double-motor driving device, two small-power motors are utilized to output moment in a coupling mode, therefore, needs of input power of the finished vehicle are met, the layout is utilized reasonably, and large brake torque required by the large-tonnage forklift is achieved by means of the attached parking brake.

A shock caused due to a change in the direction of torque transferred to an output shaft is reduced. There is provided a control device for a powertrain including a drive power source that transfers torque to an output shaft connected to a wheel of a vehicle, and a rotary electric machine that transfers torque to the output shaft via a transmission. When electric power generation performed using the rotary electric machine is restricted, if torque that decelerates the vehicle is transferred from the drive power source to the output shaft, a control is executed so that torque that does not decelerate the vehicle is transferred from the drive power source to the output shaft, and a shift control over the transmission is executed.
