Vehicle control electronic product software development process

The software development process for automotive vehicle control electronics is a "V" shaped development process. The "V" shaped development process is divided into five phases, i.e., functional design, prototype simulation, code generation, hardware-in-the-loop simulation-HIL, and calibration.

　　The main tool used in the functional design stage is MATLAB, and by using Simulink, Stateflow, and other tools provided by MATLAB, we complete the tasks of designing the control scheme, designing the functional modules, designing the control algorithms, etc., and carry out the preliminary simulation work. The main tool used in the prototype simulation phase is dSPACE. offline simulation work is done using the Rapid Control Prototyping-RCP tool provided by dSPACE. Before starting this phase, it is necessary to use tools such as Real Time Workshop, Targetlink, etc. to complete the conversion of code generated by Simulink, Stateflow, etc. to standard C code.
