Propulsion System Integration

The PSI Presentation is designed to evaluate the teams’ architectural decisions, current vehicle status, mechanical & electrical design and engineering methodologies. Teams will need to demonstrate forward thinking in their problem solving, understanding the critical interactions of each functional area within the PSI swimlane and how they affect the VTS. This will be achieved through providing one example of complex system within their vehicle architecture.

Controls & System Modeling and Simulation (CSMS) Presentation

This CSMS Presentation will focus on the development of plant models for propulsion system architecture selection and establishing a control system architecture. A control system architecture is the high level physical system/structure for controls including: ECUs, interfaces, serial data and other communication busses, key sensors, HMI and actuators added to base vehicle. In addition to this, any requirements that have been developed, energy management strategy research, and CAVs (Connected and Automated Vehicle) team interactions achieved in year one is within scope for this event. Additional focus areas of the presentation include: model-in-the-loop simulation methods, including model development strategy, requirements management, testing techniques, results evaluation, creation of a control architectures and how these processes are applied to optimum vehicle propulsion system architecture selection, controls development and achieving CAVs goals.

Connected and Automated Vehicle Systems (CAVs) Presentation

The Year 1 CAVs Presentation is designed to evaluate the effectiveness with which the team completed the CAV activities throughout the year. CAV teams in Year 1 should be focused on sensing system design and simulation, computing hardware selection, sensor fusion algorithm testing, basic longitudinal control and mule vehicle sensor data collection using sensor hardware. The presentation itself will focus on several aspects of these activities: hardware system design, sensor fusion algorithm development, and software development workflow and processes.

Project Initialization Approval (PIA) Presentation

The PIA Event for year one of the EcoCAR mobility challenge is focused on vehicle architecture selection and the selection of the major vehicle subsystems to meet the team’s Vehicle Technical Specification (VTS) goals. The intent of this event is to allow each team the opportunity to demonstrate an understanding of the vehicle architecture selection process, the advantages and limitations of the selected architecture and how the particular architecture affects the overall vehicle balance to the VTS requirements. The focus of this presentation will be at the vehicle level with references and connections made to the major subsystems. A high-level understanding of the vehicle integration areas (occupant packaging, subsystem packaging, mass, thermal performance, dynamic performance, noise & vibration performance, system safety, and fuel economy) is expected to be demonstrated. A description of how the vehicle performance analysis and simulation were done is required such that VTS targets will be achieved within a bandwidth of confidence. Vehicle integration and performance balance should be the emphasis of the presentation. Particular emphasis will be placed on evaluating the relationship between the vehicle architecture chosen, the VTS, and competition cost. The presentation should also include information on the propulsion system hardware architectures chosen, including how these subsystem selections achieve the desired vehicle performance balance and achievement of the VTS.

Target Market Presentation

The first step in any product development process is to define the customer. A set of technical specifications for the product can then be established to quantitatively define the characteristics of the product which will appeal to the targeted customer. Finally, the product can be engineered to meet those specifications. For the purposes of EcoCAR, some elements of the target market have been pre-defined: teams must design a car for a Mobility-as-a-Service (MaaS) market, specifically a fleet-owned carsharing application (similar to Maven or Zipcar). By nature, this is a dual market where the vehicle must appeal to both the fleet-owner (operator of the carsharing service and purchaser of the vehicle) and the customer (the person that subscribes to the carsharing service and drives the vehicle). In this presentation, teams will define and characterize both the fleet-owner and the customer for this MaaS market and justify that the geographical region of this market suitable to support a carsharing service. Teams will also discuss the wants and needs of the fleet-owner and the customer as it pertains to the vehicle, including any areas where the fleet-owner and customer diverge. Finally, teams will present a single set of Vehicle Technical Specifications (VTS) that combines the wants and needs of the fleet-owner and customer into a unified vehicle design.

Project Management

Project Strategy and Risk Review Presentation

In the Project Strategy and Risk Review Presentation, student Project Managers will present details about the architecture selection process through the lens of project management, covering any consideration that could potentially affect the time, scope, or budget of the project once the team begins to execute their selected architecture. PMs will deep dive on risk analysis and the strategic decision-making process they applied to the architecture selection process, including the methods, tools, and processes used, the specific risks identified, and how those risks impacted the team’s decision-making process. PMs will also present the risk profile of their selected architecture, justify the risk-benefit value proposition, and discuss future plans for executing the architecture including how to manage risk throughout the project
