Application of sensors for
automotive
Equipment conceived to study different sensors, depending on technologies, types of regulation, capturing
parameters and means of transmission of information used in the different electrical electronic systems which
can be found at present in a vehicle. Thanks to these sensors the electronic systems receive information of the
physical and or chemical magnitudes necessary through the ECU in order to make the calculations required to
start the different actuators working. The actuators will be in charge of producing the physical variations which
make the different electromechanical components of the vehicle work. The equipment has 12 sensors, similar
to those actually used in the car (CKP-CMP-MAF- MAP etc.) through which and thanks to the combination
of different technologies used in their construction a high number vehicle sensors can be studied. Some of
the signal reception elements can be connected to the UCE ADA304 application, and along with the ADA305
actuator they make the equipment form a complete electronic control system.

ECU electronic control unit
Equipment to study how the electronic control unit (ECU) of a petrol engine works with a multipoint sequential
injection system and static ignition. The equipment enables, by means of a series of potentiometers, different
operation conditions to be simulated (amount and air mass, temperature, rpm, cooling temperature etc.) which
the ECU, depending on the programming, uses to carry out the necessary calculations and make the different
system actuators work (injectors, coils, air flow valve, electrofan, etc). Input and output signals can be adjusted
independently. Nevertheless, to avoid malfunctions (unlikely) on the injected system, an AUT mode has been
implemented where the sensor signals evolves depending on the programmed algorithm thus allowing the
student to quickly begin to understand how the injection system works. Similarly, it incorporates the auto-
diagnosis system which alongside the DD-Car software allows the student to become familiar with auto-
diagnosis techniques.
