AV-ECD Automotive Electronic Control Device Unit
The Automotive Electronic Control Device Unit, "AV-ECD", provides a practical solution to the introduction of electronic control units or ECUs. The unit emulates a group of the main sensors and actuators used in modern cars to introduce the user to the ECU common functions.
The "AV-ECD" unit includes a series of emulated sensors and actuators that generate and receive the same signal like a real automotive sensors and actuators. The emulated sensors and actuators included in the unit are focused on the engine management system: knock sensor, engine coolant sensor, lambda sensor, camshaft position sensor, turbocharger boost control solenoid, electronic throttle valve, engine cooling fan, etc.
The communication protocol of the ECU varies depending on the characteristics of the sensors and actuators connected. This communication with the electronic control units can be done through CAN or LIN network protocols or through digital or analog signals.
The "AV-ECD" unit is mounted on a metallic plate that can be used alone or assembled to the EDIBON workbenches.
All sensor and actuator circuits included in the unit are isolated to understand the function of the circuits separately. Each circuit has different test points accessible through 2 mm standard lab sockets.
The "AV-ECD" circuits include a series of faults, which can be inserted to the input and output signals of the ECU, to allow the students to detect and understand common failures of the electronic components.
The "AV-ECD" unit is provided with a different set of practical exercises, through which the student will understand how the electronic control units work.
