Development of a Drivecycle-based Twin Drive Control Procedure to Increase the Efficiency of Electric Motors

The aim of our research is to develop an efficient algorithm for the automatic switching of gear shifters located in the drives of regular buses equipped with electric twin drive. In this paper, a report is presented on our progress with the procedure for back-calculating electric motor efficiencies from driving cycles. The mechanical calculation for determining the efficiency has been completed for vehicles equipped with single drive. In order for the method to be used for twin drives as well, additional emerging problems must be solved, which will be described in the second half of this document.
