Teaching Experimental Applications (View Specification (docx))

  • Analysis of how the different actuators work.
  • Testing electrical/electronic signals with without voltage and under voltage.
  • Diagnosis of faults in the actuators: Lack of supply, actuator broken, short circuit to mass or to actuation positive, failure in the communication bus of the actuator (CAN-LIN).
  • Instrumentation handling: Oscilloscope, Polymeter

Technical details

  • Autonomous equipment for the study of actuators in a car.
  • The actuators shall include the following equipment:
    • Ignition coil with incorporated spark
    • Electromagnetic injector
    • DC Motor:  Open loop speed control and closed loop control position potenciometre on the shaft.
    • Cooling fan: Analogue or series resistance speed control
    • Electro valve: All/Nothing Control (ON/OFF) and linear control by means of Pulse Width Modulation (PWM).
    • Electromagnet: ON/OFF Control
    • Windscreen washer motor pump: Motor pump control in both directions.
    • Step Motor: Two working speeds.
    • Actuators related with lighting: Position-brake light, emergency warning lights, lights on warning
    • Acoustic actuator, piezoelectric buzzer: Actuation of the same with two different tones.
  • The control technologies implemented are:
    • Digital control
