Automotive Drives

Developing and testing automotive drive controllers

Our solutions support you in developing and testing various in-vehicle electric drives – from vehicle traction motors to small electric motors for in-vehicle auxiliary systems. We have everything you need for testing from the signal level to the full power level. 

Challenges

Electric vehicles of today are equipped with a wide range of electric drives, from the main drive for vehicle traction to the numerous auxiliary drives for the various electrical systems onboard the vehicle, such as air conditioning, electromechanical power steering systems, and electronic braking systems. While these systems range from less safety-critical systems to those with the highest safety requirements, they have one thing in common: They all require a powerful and flexible development environment as well as extensive testing during the development phase, resulting in a wide range of testing requirements for manufacturers.

In addition, the latest trends in the automotive industry impose various requirements on state-of-the-art electric drives and their manufacturers, including:

  • Enhanced energy density
  • Increased switching frequencies
  • Increased number of switches
  • More advanced motor topologies
  • Increased controller complexity
  • Increased voltages of up to 1,000 V

dSPACE Solution

With decades of experience, we know the special requirements for electric drives in the automotive industry. We offer a comprehensive solution portfolio for virtual validation, rapid control prototyping (RCP), ECU autocoding as well as hardware-in-the-loop (HIL) and power HIL simulation. Our dSPACE solutions interoperate seamlessly to provide a convenient development and test environment. You can benefit from our various hardware products including powerful real-time processors, user-programmable FPGAs, and comprehensive I/O interfaces.

Selected Success Stories

JEE: High Voltage, Low Risk

Flexible HIL simulation based on a combination of FPGA and CPU makes motors more efficient and their development safer. For developing state-of-the-art electric drives, JEE uses HIL testing with powerful software modeling and SCALEXIO hardware from dSPACE.

Great Wall Motors: The Versatile Electric

For more than ten years, Great Wall Motors (GWM) has focused on new drive technologies as one of their development paths. Today, the GWM brand portfolio includes innovative production vehicles. During development, the company used the production code generator dSPACE TargetLink as well as other tools from the TargetLink Ecosystem.

FAW: Excellence as a Standard

First Automotive Works (FAW) develops the mobility concepts of tomorrow in line with the AUTOSAR standard. The company uses virtual ECUs as well as the prototyping system MicroAutoBox II, the production code generator TargetLink, and the system architecture tool SystemDesk to implement new propulsion technologies on the basis of models and AUTOSAR.
