Abstract
The Speed4E powertrain is based on the knowledge from the Speed2E project and is also a multiple motor, multiple speed electric powertrain. In combination with a suitable operating strategy, this architecture will increase the vehicle range and improve the driving performance compared to conventional electric powertrains [1]. Dog clutches are used as shift elements in the developed concepts. Transmission controls have already been developed at the IMS for both, the electric powertrain Speed2E and the hybrid powertrain DE-REX [2,3,4]. In these projects the gear engagement under differential speed was examined in detail. It emerges from [4] that an improvement in the comfort and dynamics could be achieved for gear changes with dog clutches with the aid of an angular position control. In addition, it is recommended to locate the control close to the motor to avoid dead times for example from CAN communication and thus to improve the control quality. In order to be able to fully exploit the potential of a gear change with angular position control, most components of the Speed4E powertrain were developed for this purpose right from the start. This includes the dog clutch, the shift actuator and in particular the control unit architecture, which is discussed in detail in this article. The central powertrain control unit serves as the coordinator of the gear change. However, the speed and differential angle control is performed close to the motor on the power electronics in order to achieve the necessary level of dynamics and control quality. At the system level, the transmission control is developed using suitable simulation models and the corresponding controllers are designed in the simulation. A particular challenge in Speed4E are the high absolute speeds of the electric motors, which require fast AD conversion and a high control frequency. Looking ahead, these operations are to be applied at a powertrain test bench and tested in a demonstrator vehicle.
