Hi 👋Friends, In this post let's understand the various types of #loop testing and their benefit's during vehicle #ECU's #development. 👉 Model-in-the-Loop (#MIL): Validation of #vehicle #Control strategies in closed loop with plant , environment & sensor / actuator models and rest bus simulation. 👉 Software-in-the-Loop (#SIL): Here validate the #generated / #handwritten #code in closed loop with plant, environment & sensor / actuator models and rest bus simulation. 👉 Processor-in-the-Loop (#PIL)🎰: Validation of #compiled #code for target #micro_controller in closed loop with plant , environment & sensor / actuator models and rest bus simulation. 👉 Hardware-in-the-Loop (#HIL)🎡: Validation of #BSW , Execution #architecture , Application software's(#ASW) real time #behavior while running on #physical #ECU's #hardware in closed loop with plant + environment + Same Act #models running on high #speed computer. 👉 Requirement-in-the-Loop (#RIL)🏌️♂️: Validation of #functionality with #real #actuators and sometimes even #real #sensors with plant model + Environment running on #HIL Box. 👉 Driver-in-the-Loop (#DIL)🤺: Validation of #user #experience and system #behavior when #human is in charge like #ABS #braking #brake pedal #vibrations. 👉 Test bed-in-the-Loop (#TBL)🔋: Validation of #performance of #Vehicle #ECU's for meeting #regulatory #standards. 👉 Vehicle-in-the-Loop (#VIL)🏍️: This phase #validates the #performance of #vehicle #ECUs in the #presence of other systems on the #test #track. ✌️It's common for #engineers to #confuse #model testing with #Model-in-the-#Loop testing. However, it's important to note that any #testing without a #plant model isn't true #Model-in-the-Loop testing. Instead, it's open-loop testing, where test #stimulation is provided via #scripts or #signal generators. While open-loop testing is #suitable for controllers like #ABS, #TCS, #YSC, #ESC, #EPS, #EMS, #MCU, #VDC, #BMS, and #VCU require a plant model for #accurate validation. #electricvehicles #ECU's #vehicletesting #closeloop #openloop #validation #BMS #VCU #OBC #TCU #MCU #Software
