Big Data, Data Analytics, and Machine/Deep Learning Infrastructure at Caterpillar
Larry Mianzo, Caterpillar
Caterpillar, in collaboration with MathWorks, has developed a big data and machine/deep learning infrastructure. The infrastructure seamlessly provides for a web-based ground-truth interface, a database for storing and querying ground-truth metadata, and an engineering interface with tight integration with MATLAB products for machine learning, visualization, and code generation. The system automatically ground-truths and labels data, dramatically limiting the need for human supervision while reducing development time. The infrastructure is scalable in the number of users, the amount of data, and the amount of available compute power.

Model-Based Software Development for Vehicle Systems at Crown Equipment
Marc McClain, Crown Equipment
Crown Equipment designs and manufactures the majority of its forklifts and components, including electric motors, drive units, power units, cylinders, electronic modules, and wire harnesses. In addition, Crown develops vehicle application software in-house, and the Vehicle Systems Group supports software development for all of Crown’s North American and European manufactured lift trucks. In 2011 the group established a goal to transition to Model-Based Design using simulation and code generation tools from MathWorks. After many iterations and a few MATLAB® releases, Crown has a simulation environment that matches the vehicle performance and is building all vehicle systems application software including that for electric steering, traction control, hydraulic load handling systems, and vehicle diagnostics.

One-Pedal Driving: Rapid Feature Development with Simulink
Nate Michaluk, Control Algorithm Engineer, General Motors
One-Pedal Driving is a drive mode that offers a revitalized set of driver controls that take advantage of the capability of electrified powertrains. One-Pedal Driving combines the highest available level of coast regeneration with intelligent speed trajectory control, bringing the vehicle to a complete stop without using the brake pedal. Engineers at General Motors developed One-Pedal Driving for the 2017 Chevrolet Bolt EV on an accelerated timeline with Simulink® as a key enabler for rapid software development. Simulink provided means to predict control algorithm performance; quickly write, test, and iterate software; and generate code to integrate into controller software.

Building a Digital Twin of Your Vehicle Powertrain with MATLAB and Simulink
Arvind Hosagrahara, MathWorks
Data analytics is changing how automotive engineering is done. Traditional methods of running statistical models on stored data reach a limit. These store-before-analyze approaches to processing vehicle data are unable to keep up with the increasing data rate due to the rising number of connected vehicles coming online. This is particularly evident in engineering applications and use cases where insight is based on a combination of physics and data.
The solution is clear—combine physics-based models from in-product development with streaming analytics technologies and cloud-based compute and storage infrastructure. Integration of this array of engineering and IT solution can be a challenge, and engineers’ involvement plays a crucial role. In this presentation, Arvind shows a successful integration using MATLAB® through the “digital twin of vehicle powertrain” demonstrator.
Developing Prognostics Algorithms: Data-Based and Model-Based Approaches
With the wealth of available data from testing and connected vehicles, and recent advancements in big data and machine learning technologies, prognostics algorithms—algorithms that can predict component failures before they occur—are receiving lots of attention.
Two approaches are commonly used in developing such algorithms:
Data-based: create predictive models using sensor data and machine learning approaches
Model-based: compare sensor data with physics-based models of ideal behavior
In this session, you will learn how to implement both approaches in MATLAB® and Simulink®. We also discuss how such models can be taken into production, enabling companies to improve the reliability of their products and build new predictive maintenance services.
