Descrição Geral

The Automotive Electronic Control Device Unit, "AV-ECD", provides a practical solution to the introduction of electronic control units or ECUs.

The Automotive Electronic Control Device Unit, "AV-ECD", is composed of an Electronic Control Unit (ECU) configured to work with the emulated sensors and actuators included in the unit, but the "AV-ECD" can also work in conjunction with other EDIBON units: it can operate with the sensors of the Automotive Sensors Unit, "AV-S" and with the actuators of the Automotive Actuators Unit, "AV-A".

The "AV-ECD" unit includes a combination of sensors and actuators that generate and receive the same signal as the sensors and actuators of the automotive computers. 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.

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 sensor and actuator circuits allow the simulation of faults in the components, inserted with toggle switches. The system faults are indicated by the malfunction indicator lamp (MIL). The sensors and actuators can work individually or with other related sensors and actuators.

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 faults 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.
