Responsibilities

Design, develop, and integrate virtual models representing both hardware and software behavior for power closures systems such as actuators, struts, latches, sliding window (closures system related mechatronics components) into co‑sim frameworks for Electric Vehicle (EV), Plug‑in Hybrid Electric Vehicle (PHEV), and Internal Combustion Engine (ICE) programs to enable power closures systems performance and controls software development, calibration, and validation.
Develop and integrate multi‑body (MBD), Flex Body and 1‑D kinematics models for various closures components including hood, side doors, liftgate, decklid etc. (Simpack models) with Functional Mock‑up Unit (FMU) and sensor models such as the Inertial Measurement Unit (IMU) into Software‑in‑the‑Loop (SIL) and Hardware‑in‑the‑Loop (HIL) simulation platforms.
Align software releases, calibration milestones, and vehicle hardware release milestones to ensure the virtual vehicle co‑simulation package is consistently up to date.
Support resolution of program issues by aligning co‑simulation partners to meet technical and timing demands.
Act as the single point of contact for Closures Systems co‑sim users, resolving usage concerns.
Support forecast and planning needs, escalating needs for required resources.
Help identify strategic opportunities for innovating processes and methods.
Knowledge of power functions of closures systems including mechatronics details about DC Motors, controllers relative to calibration and validation of closures systems.
Develop, evaluate, review and verify guidelines for Functional Mock‑up Unit (FMU) models provided by suppliers for various closures systems based embedded controller models for actuators, latches, glass guidance system etc.
Build a library of closures systems mechatronics modules that can be integrated for program specific work.
Create developmental test procedures to enhance virtual vehicle development, calibration, and validation, and work with suppliers to troubleshoot issues in the virtual models provided for those activities.
Perform closed‑loop learning to validate the performance of power closures co-sim models and analyze simulation data against vehicle data to improve the fidelity of the virtual calibration/validation models.
Develop and validate automated simulation run scripts using MATLAB, Simulink and Python etc.
Support implementation and utilization of Simulation Data Management (SDM) and version control tools to manage vehicle dynamics plant models and virtual controller models, effectively leveraging tools like GitHub for that purpose.
Define requirements for supplier co‑sim packages, and work with them to ensure consistency of deliverables in terms of quality and timing, escalating issues as appropriate.
Ensure co‑sim packages meet standards as defined by the SIE governance team.
Represent the needs of vehicle dynamics among SIE peers from other disciplines.
Advocate for adoption of virtual methods for vehicle design, development, and validation.
