Control Strategy of Knob Operated Shift for Electric Vehicles

We developed knob operated shift control strategy used on pure electric vehicles by use of Matlab 2015b and its Embedded Coder (EC) toolbox based on the V-model development process. Firstly, the functional requirements of knob operated shift strategy were analyzed, a simulation system based on finite-state machine was established in Simulink/Stateflow, the input and output signals, and the parameters of the model were scaled. Secondly, C code were automatic generated by use of EC toolbox, test cases were compiled with Excel, model in loop (MIL) and software in loop (SIL) auto test tool were used and the model was tested and modified. Test results indicate that, under different conditions, the dynamic response of knob operated shift function meet the design requirements.
