Keynote: Transforming Software Development for Future Autonomous, Electrified, and Connected Commercial Vehicles

Micha Muenzenmay, Robert Bosch
Mouham Tanimou, Robert Bosch

Innovative use cases in the field of autonomous, electrified, and connected commercial vehicles, as well as changing usage, lead to the need to add functionality after production.

Today, software features are defined during development. Later, new functionality or application updates can only be done in the service workshop or by specialist on site, if at all.

To change this situation, Bosch develops an open ecosystem starting from the development environment in the cloud up to the global management, licensing, and distribution of software applications, with new simulation and model-based design approaches woven into the workflow. The ecosystem supports a uniform function development approach throughout the lifecycle of the vehicle, from concept through aftermarket.

This approach enables the introduction of customer-specific functionality, on short notice and at any time worldwide. A Firmware-Update-Over-The-Air (FOTA) as well as adding dedicated software applications (Software-Update-Over-the-Air, SOTA) is supported.

This presentation discusses the basic approach and development steps, and gives examples.

Building Battery State-of-Health Estimation Pipelines for Electrified Vehicles

Nilesh Kulkarni, NIO Inc.

This talk gives an overview of battery state-of-health (SOH) estimation and prognostics modeling that uses data generated from the vehicle model in the cloud. The vehicle model is comprised of a Simulink^® based electric vehicle model that includes Li-Ion cell chemistry-based battery models. While building battery state-of-health pipelines, it is difficult to capture real data from the vehicle in various driving conditions. We took the approach to leverage a calibrated Li-Ion Cell Chemistry model to generate the required data in various driving conditions. We pushed this data to the cloud, then had the data pipelines pick this data and do all the downstream processing. This enabled us to build the data pipelines and the analytics stack without having extensive vehicle data. As we have now started getting real data, we are validating this analytics stack. This talk also discusses leveraging the Simulink code-generation feature to generate C-code and its feasibility for real-time in-vehicle SOH estimation.

System Simulation for Robust Calibration and Diagnostics

Mert Zorlu, Cummins Inc.

Cummins Inc. is the world’s largest independent diesel engine manufacturer, celebrating their 100th year of operation in 2019. Cummins manufactures and supplies engines ranging in displacement from 2.8L to 95L using a variety of fuels to a diverse customer and applications base across the globe. The combination of tightening global emissions standards, increased customer expectations with regards to reliability, and demands for improved fuel economy from production line to Emissions-Useful-Life (EUL) presents a complicated set of technical challenges across all their product lines.

To help meet these technical challenges, Cummins is utilizing MathWorks tools to perform simulations both in a hardware-in-loop (HIL) environment as well as using a fully virtual model-in-loop (MIL)/software-in-loop (SIL) environment with engine and aftertreatment plant models. Using these models, Cummins can perform both sub-system and system-level performance characterization and robustness testing, which is typically expensive, difficult, or impossible to accomplish in the real world. This simulation data is used to provide guidance to programs on controller tuning and to inform decisions on system performance and diagnostic robustness.

System simulation (engine, aftertreatment, and controls) use cases for performance and diagnostic validation using MathWorks tools are demonstrated in this presentation. Evaluation of model fidelity, identification of customer clusters, noise factor robustness testing, system simulation, and evaluation of performance and diagnostic capability use a number of tools to deliver efficient virtual product validation. Using examples from a recent program, Cummins shares how MathWorks tools are being applied in support of continuous product improvement efforts.

Planning Model Architecture and Modeling Patterns for ISO 26262 Compliance

Jason Moore, MathWorks

The ISO 26262 standard for functional safety provides guidance on the development of automotive electronics and electrical system, including embedded software. A common challenge is to determine the strategy, software architecture, and design patterns up front in a project to achieve standard compliance and to avoid mid-project changes to these foundational areas. In this presentation, MathWorks engineers will address the following topics based on their experiences applying Simulink^® to production programs that require ISO 26262 compliance.

• Key considerations for model architecture for ISO 26262 compliance
• Modeling constructs required to meet freedom from interference
• Applying the above best practices to meet AUTOSAR at the same time

Keeping System Documentation Current With the Increasing Pace of Agile Product Development

Bharath Sundar, Delphi Technologies
Jim Allen, Delphi Technologies

The fast pace of the Agile methodology requires OEMs and Tier 1 suppliers to work hand in hand to develop and refine requirements and make quicker interim deliveries. Advances in Simulink^® and Polarion^® ALM have facilitated requirements linking to models assisting systems engineers in developing and documenting requirements for the new control strategies. Advances in MATLAB^® and Simulink Report Generator™ enabled the auto-generation of documentation from the models assisting systems engineers to create current and correct documentation for the customers. A concept will be proposed to merge linked requirements in Polarion ALM with the auto-generated documents from Simulink models. Known APIs that can enable this merge will be summarized. This proposed concept will provide an all-encompassing auto-generated document that will save time in providing up-to-date documentation for controls and diagnostic strategies.

Reinforcement Learning: Leveraging Deep Learning for Controls

Aditya Baru, MathWorks

Reinforcement learning allows you to solve control problems using deep learning but without using labeled data. Instead, it uses a model of your system that captures the appropriate dynamics of the environment, and learns through performing multiple simulations. This simulation data is used to train a policy represented by a deep neural network that would then replace your traditional controller or decision-making system.

In this session, you will learn how to do reinforcement learning using MathWorks products as well as how to set up your environment models, define the policy and its various hyperparameters, and scale training through parallel computing to improve performance.

Full Vehicle Simulation for Electrified Powertrain Selection

Mike Sasena, MathWorks
Kevin Oshiro, MathWorks

Full vehicle simulation models are needed to assess attributes such as fuel economy and performance for each candidate. At times, this requires integrating models from different engineering teams into a single system level simulation.  Integrating these subsystems, including many controllers in model or code together in a closed-loop testing environment, can be challenging.

Virtual Design of Electrified Powertrain Systems

Javier Gazzarri, MathWorks
Dakai Hu, MathWorks

Electrified powertrain engineers design the battery pack, power electronics, and electric machine to meet requirements cascaded from vehicle system level simulations. The motor is energized by a battery that is far from being an ideal voltage source. For example, power delivery from the battery varies as a function of battery State of Charge (SOC), State of Health (SOH), and temperature. On the motor control side, optimal id/iq combinations need to be calibrated, considering fluctuations of the voltage source. In this talk, MathWorks engineers will show how to design a system that is robust to battery power delivery fluctuations.

Objective Drivability Calibration

Jason Rodgers, MathWorks

The effect of the ECU on drivability can be dramatic, and requires time for proper calibration. Traditionally, experienced drivers test a vehicle during tip-in/tip-out maneuvers and provide a subjective drivability rating, iterating on ECU calibrations until the subjective feel is acceptable. Using simulation-based methods, it is possible to conduct much of this analysis up front using objective methods. By extracting key features from the acceleration results, an objective metric can be obtained. Formal optimization methods can identify a calibration set that provides a much better drivability response for the initial in-vehicle tests, thus reducing the overall time required. In this session, you will learn how MathWorks tools for data analysis, vehicle modeling, and calibration were applied to perform objective drivability calibration.
