Model-Based Development(MBD)

In automobile-related development, model-based development will become increasingly important. MBD engineers in various sectors who are well versed in the products and capable of designing products will provide services according to our customers’ needs.

Relationship between model-based development and each step

The need for MBD

Existing issues

MBD offers many benefits!

Actual equipment-based validation

Since actual equipment does not exist in the design phase and development of a prototype is costly, validation proceeds slowly.

A model of the “item” to be controlled is supplied

Since a model of the “item” to be controlled is supplied, validation testing through simulation on a PC is possible and it streamlines the development process.

Growing cost due to reworking

If a specification-level error is found at a later phase in development, such as during the validation of actual equipment, extensive reworking is necessary.

Validation in advance to prevent reworking

Through simulation in the early phases of development and repeated validation, defects that would be found in the later phases of development can be eliminated in advance.

Manual programming

Manual programming based on the specifications creates issues such as human errors and manhours.

Automation conversion from model

A model can be automatically converted to C code without manual programming. Accurate C code can be rapidly created.

Barriers to reaching an understanding between different fields

Problems such as misunderstanding tend to occur in communication between the different fields.

Simulation is intuitive

Simulation results can be visually understood. Integrated simulation including mechanics, control, and electronics can be performed.
