Develop Plant Models for Propulsion systems and IO Models for HIL.
Integrate IO & Plant Models and maintain Model architecture roll-out for different systems.
Create test specifications from System/software/controls requirements and validate using dSPACE platform tools.
Automate test cases using Python and execute the test script.
Coordinate HIL bench deployment and support for Propulsion systems HIL benches.
Plan, communicate, and coordinate HIL Test strategy and automation framework rollout.
Design and develop fault injection solutions for sensors, actuators, and communication buses.
Design hardware simulators for vehicle components such as inverters, motors, batteries, fuel cells, etc.
Develop HIL harnessing and hardware interfaces for simulated components.
Develop support Human Machine Interfaces (HMI) or GUI for HIL test execution and rapid prototyping.
Maintain HIL system architecture following requirement updates and evolution.
Develop HILST test environments for Vehicle ECU subsystems testing, verification, and validation.
Design/Develop HILST environment using a model-based engineering approach (Simulink / Stateflow).
Capture functional requirements for HILST environment to satisfy ECU/Systems test.
Support development of bespoke modules and configure commercial tools as required.
Produce and deliver HIL Systems to a defined release plan.
Simulink S-Function development and integration for Plant/Controller Function Simulation.
Use/integrate Plant/Vehicle Models as required (Carmaker/DSpace ASM).
Utilize Test Automation Tools (Automation Desk/Python Development).
Deliver software test results to Engineering and support development of test requirements with system engineers.
Work collaboratively with other HIL engineers to align processes and improve development efficiency.
