LMS Imagine.Lab solutions for transmission For control design, virtual testing and pre-calibration
• Model In the Loop:
• Design the transmission control strategies with help of a representative plant model
• Virtual models for the control and the transmission
Hardware-in-the-Loop:• Test and validation of the control strategies
implemented on the Control Unit
• Regulation, security and failure tests without any
risk
• Test of the interaction between several
ECU/TCUs…
Software-in-the-Loop:• Test the C-code used in the controller using a plant model including CAN or FlexRay protocol
• Test using the generated C code (using AMESet) or a Simulink model
• Possible tests in a “virtual” real-time environment
Virtual pre-calibration:• First step of control calibration (offline) using
detailed engine/vehicle plant models
• Put the control in usage context for a simulation
of a virtual vehicle
• Reduce time and cost of test on the real
system

• In AMESim• Add Simulink Interface in the AMESim model
• Run the AMESim model off-line (passing from the parameter mode to the simulation mode – thus generating the s-function)
• Generate files for real-time simulation
• In Simulink and RT-LAB• Add s-function block and specify the C source file name and parameters
• Run the model offline with fixed-step solver and verify results
• Run the model in real-time and compare the results

• OPAL-RT and LMS have collaborated for about 6 years
• Enable real-time simulation of these models on OPAL-RT platforms.
• AMESim has tools that allow the user to adapt models for real-time simulation by optimizing model reduction.
• This integration allows powerful real-time plant simulation capabilities for HIL
• Open approach that allows customers to use modeling tools of their preference
• Tools can be used together for a complex system such as a hybrid bus, for which HIL is absolutely critical for integration testing of multiple ECU
