A DSP-based integrated starter/generator controller for single-axle parallel hybrid powertrain

The controller design is a challenging task for the electric propulsion system (EPS) of the hybrid electric vehicle (HEV), which influences the economical efficiency and emission performance of HEV significantly. A single-axle parallel hybrid powertrain configuration for the IVECO vehicle is described firstly. Secondly, a DSP-based controller design procedure including hardware and software is given in detail. Finally, the controller with the integrated starter/generator (ISG) is tested in the test bench. The test data shows that the controller works well together with ISG and the controller satisfies the performance requirements of the single-axle hybrid powertrain.
