Developing and testing electronic control units
Application Areas of Electric MotorsIn automotive applications, electric drives are being incorporated into several complex, basic, and safety-relevant vehicle functions. Some examples of automotive applications are
- Electric steering systems
- Powertrain actuators
- Starter-generator systems
- Electric vehicle
- Mild/full-hybrid systems
- Electric brake system
- Electric window lifter
- Auxiliary aggregates: Oil pump, water pump, etc.
Electric motors are also in widespread use in the capital goods industry, medical technology, and aerospace sector. Aerospace applications especially have high requirements regarding safety and reliability.
Other applications include:
- Wind energy converter
- Electric trains
- Printing machine
- Roller mill for cold and warm roll forming
- Zinc coating plant (headway and drive control)
- Artificial respirator
- Magnetic resonance tomography
- Bipedal walking robot
Developing with Rapid Control Prototyping
Advantages of Rapid Control PrototypingTo develop a new control strategy, you have to evaluate different approaches and functions. You need to concentrate completely on your function development and should not have to worry about the performance of the prototyping hardware. Ideally, you can optimize your function designs both on the test bench and in the actual vehicle or industrial drive system, until they meet the requirements – all without having to do any programming.
Testing with Hardware-in-the-Loop Simulation
Advantages of HIL SimulationAfter the ECU functions have been developed and implemented on the production ECU, they have to be tested thoroughly. With hardware-in-the-loop (HIL) simulation, you can easily cover all the different motor varieties and their ECUs.
The ECU’s environment (interacting components or even a whole system), is simulated.
This has several advantages:
- Function tests are possible at an early development stage, even before all parts are available in reality.
- Laboratory tests reduce time and cost and take place under controlled conditions.
- Failures, and the ECU’s behavior in what are normally dangerous situations, can be tested with no risk for the driver or the controlled machine.
- The tests are reproducible and can be automated.
