How Companies are Adapting to the Systems Engineering Approach in the New Era of Autonomous Vehicles?

ADAS (Advanced Driver Assistance System) technology is gaining traction across the globe as we look forward to Highly Automated Vehicles (Hands Off, Eyes Off – Conditional Automation & Hands Off, Mind Off – High Automation) and Autonomous Vehicles (Driver Off) with respect to Transportation and Mobility.

Several experiments are going on in the space of UAV, UGV, UUV and USV to bring a new era in the field of Autonomous Vehicles. There are several challenges to address the Automated Vehicle solutions with respect to traffic jams, auto pilot, highway auto pilot, urban auto pilot, self-driving. Some of them are listed below:

  • How to sense the environment?
  1. Which sensor to be selected keeping in mind the safety and cost factors?
  2. Positioning of sensors impacting the weather conditions
  • Communication between Humans and Machines
  • Integration of Electrical/Electronic Architecture by making Vehicle centralization requires Big Data from sensors and cloud
  • Adaption of Vehicle Charging and its infrastructure
  • Remote Control of the Autonomous Vehicle
  • Collision avoidance with other Smart Systems
  • Safety alerts for pedestrians
  • Alerts for real time traffic, road conditions and so on…

Most of the companies are looking for an integrated platform to manage the entire data namely Mechanical, Fluid, Electrical and Electronics with a Model Based Approach.

To address the above challenges, Dassault Systèmes has come up with a solution on how the Systems of Systems, Cyber Physical Systems and its Sub Systems can be integrated.

To manage the entire Systems, System of Systems and its Sub Systems, there should be a seamless integration. 3DEXPERINCE platform from Dassault Systèmes not only addresses the challenges of integration, it also addresses the Real time Monitoring challenge by having a Virtual Twin of an entire Assembly of a Vehicle or an Aircraft or complete Factory as well.

It eases the workflow to have a First-Time Right-Information along with possibility of successful Technologies to validate virtually with respect to Model Based Systems Engineering.

The below picture indicates how detailed up stream and downstream thinking processes take place from OEM to suppliers and the different disciplines involved from different domains which needs to communicate with each other.

For any autonomous vehicle, camera, radar, sonar and lidar are essential which SENSE the environment through SENSORS and process the data through Software Applications like Apps, BSW, OS. Computing & Load Balancing are done through Processors, ECU’s, GPU’s which will COMMUNICATE with Humans and Machines through Communication Protocols & Cyber Security (Cables & Wires, Wireless Communication) and Human Machine Interface (Head Up Display, Voice, LED’s) which Act (Power, Move, Sound, Heat, Cool) using Actuators (Mechatronic Parts) and Power Management (Power & Battery).

The above process consists of lots of sensor-based applications, software applications, mechatronics applications which needs to communicate very strongly in the R&D Phase of any product and it is very critical to have a virtual testing before moving to real testing so as to achieve the “right” design for the first time.

The validation and digitilization of some areas are very critical as they play a major role in the emerging technologies:

  1. As electronics is transforming the automotive experience, it is always important to manage the electronics signal & power integrity workflow to be maintained digitally by capturing the requirement, schematic capture/ component placement, circuit simulation, pre-layout simulation SI/PI, post layout simulations after importing, EMC compliance check.

As the compliance for any new emerging technologies will play a key role, Dassault Systèmes through 3DEXPERIENCE Platform is offering Industry Process Experiences to address these challenges.

  1. There is a need to have a full traceability for all the functional, logical, physical requirements with respect to validation, testing and communication for which performance driven architecture process available in 3DEXPERIENCE will help to streamline the processes.
  • EV technology poses lots of challenges to the R&D department to prove the concepts. This requires complete behavior modelling and multi-scale/multi physics simulations of aerodynamics, structure, ride & handling. These can be validated using 3DEXPERIENCE On Cloud solutions from Dassault Systèmes.
  1. ADAS/AV sensor design & placement virtual validation is very important as all the modern cars come with complex electronic systems on four wheels. OEMs (and suppliers) are responsible for compliance/ electromagnetic compatibility, reliability, safety and comfort which 3DEXPERIENCE Platform provides by having a digitalized workflow of sensor modelling with antenna array design, EMAG field simulations, soil performance simulations and so on.
  2. Vehicle antenna design displacement plays a vital role in ADAS technology to find the optimized antenna placement and vehicle shapes based on KPI’s.
  3. There is a possibility of validating the design and get experienced in immersive environment through VR for the design reviews through the 3DEXPERIENCE platform.

 

With the automotive industry shifting gears to autonomous vehicles and many start-ups venturing into this segment, EDST is proud to have played a significant role in business transformations with proven industry solutions and applications.

Automate your CAD using CATIA V5 Macros

Performing repetitive tasks manually leads to a loss of productivity. This is one of the major reasons why organizations are increasingly trying to automate processes which helps to reduce manual labour, design time and increase productivity. In CATIA V5, repetitive manual tasks can be automated using CATIA V5 Macros.

There are two ways to create CATIA V5 Macros:

  1. Recording a macro.
  2. Writing a macro.

How to record a macro in CATIA V5:

  1. Launch CATIA V5 & Go to Tools 🡆 Macro 🡆 Start Recording.
    Automate your CAD using CATIA V5 Macros-1
  1. Now, you can specify the macro library in which you want to save the recorded macro, specify the name you want to give to the recorded macro & click Start.
    Automate your CAD using CATIA V5 Macros-2
  1. Now, perform the operations which you want to automate in CATIA V5 e.g., Open Part Design Workbench 🡆 Create A Sketch 🡆 Create Pad.
  1. Once all the operations which you want to automate are completed, click on Stop Macro Recording.

  1. Now, to perform the task automatically, run the recorded macro by clicking Tools 🡆 Macro 🡆 Macros or simply by pressing Alt+F8 keys.
    Automate your CAD using CATIA V5 Macros-2
  1. Now, select the Macro Library, the macro which you want to run & click on Run.
    Automate your CAD using CATIA V5 Macros-5
  1. The task will now be performed automatically e.g.; pad is created automatically.
    Automate your CAD using CATIA V5 Macros-6

You can modify the recorded macro and use that macro to create all the variants of a product.

For example, if you need to create multiple bolts which are having different diameters then you don’t need to create all the bolts manually, you can automate the bolts creation process and the parameters can be entered using “input-box”.

How to write a macro in CATIA V5:

CATIA V5 Macro can be written in three languages:

 

  1. Visual Basic 6
  2. VBA
  3. VB Script / CATScript


Applications of CATIA V5 Macros:

Macros can be used for automating the below set of scenarios:

  • Repeated set of tasks: Create/Insert customised title block, saving images of annotation views to PowerPoint, extract BOM table to excel, etc.
  • Create templates & standardise the company work flow: For example, you have a standard template of part in which only few parameters might vary. The part can be created using automation and the parameters can be put in by the user.
  • Quality checking process: Macros can be used to automate the predefined quality checks like checking whether material is applied, font style in drawing, proper tree structure in assembly etc. Based on the check results, we can perform additional tasks.


Advantages of CATIA V5 Macros:

  • Faster completion: 90% of the time can be saved in product design using CATIA V5 Macros.
  • Error free: As there is no human interaction while performing the repeated set of tasks, there are minimal chances of error.
  • Run the automation during non-working hours: As macros can work automatically, repeated set of tasks can be performed during non-working hours which ultimately increases the productivity by reducing design time.
