Realistic Results with
Highly Dynamic Tests
The realistic results of the highly dynamic test, for example for an EPS control unit and motor, are ensured by
- sophisticated models of steering system/ vehicle dynamic
- realistic parameter sets for every model
- highly dynamic torque control for actuator
The HiL-tests are characterized by
- universal application even for the production of EPS ECUs/ motors
- high performance
Standardized Road Tests with
Highly Dynamic Excitation
With the conduction of standardized road tests with highly dynamic excitation of the EPS system such as
- fishhook and
- double lane-change
the high performance of the power pack test bench is proven. The HiL-system match the simulation results of the real-world system very well. Due to the sophisticated control system, the measurement results are not negatively influenced by the intrinsic behavior of the test bench. The quality of the results therefore depends significantly on the simulation model used.
Customer Application
The DMecS power pack test benches are successfully used for the testing of customer powerpacks. These include
- system identification regarding the torque generation dynamic
- automated testing of motors for a torque feedback steering system
- parameter identification for differential lock actuators and servo drives
- reduction of torque ripple
With the reduction of the cogging torque induced torque ripple its impact on the torsion bar torque/ drivers hand torque can be positively influenced.
