This respository describes the OBDII dataset adquired during my master thesis. The dataset is composed by 27 different vehicle parameters (PIDs). The data acquisition system is composed by an embedded system connected to the On-Board Diagnostic II (OBD-II)interface of a Toyota Etios (year 2014, Engine Displacement1496 CC). The device used was the Carloop, an open-source development kit based on a microcontroller with cellular connectivity and OBD-II interface connector. The systemcaptures all vehicular data at a rate of one sample per second (1 Hz).
- Vehicle parameters
The following parameters are available in this dataset:
| Car parameter | Variable name |

| Run time since engine start | ENGINE_RUN_TIME |
| Engine RPM | ENGINE_RPM |
| Vehicle Speed | VEHICLE_SPEED |
| Throttle position | THROTTLE |
| Calculated engine load | ENGINE_LOAD |
| Engine coolant temperature | COOLANT_TEMPERATURE |
| Long term fuel trim—Bank 1 | LONG_TERM_FUEL_TRIM_BANK_1 |
| Short term fuel trim—Bank 1 | SHORT_TERM_FUEL_TRIM_BANK_1 |

| Warm-ups since codes cleared | WARM_UPS_SINCE_CODES_CLEARED |
- Vehicle modes
The drive files refer to the car in the motion mode (moving on roads), differently, IDLE mode refers to the vehicle stopped in parking mode, but with the engine on. The files in the dataset correspond to specific conditions of the vehicle:
idleX.csvrefers to the vehicle in the IDLE modedriveX.csvrefers to the vehicle in motion mode in high speed roadsliveX.csvrefers to the vehicle in a specific traject (work --> home)ufpeX.csvrefers to the vehicle in motion mode inside an university campus (low speed)longX.csvrefers to long trips with the vehicle in motion mode.
This is a open-source repository, free to everyone. If you use PLEASE CITE MY ARTCILE AS REFERENCE OF THE DATABASE. The work of my master thesis (Detecting Anomalies in the Engine Coolant Sensor Using One-Class Classifiers) are available ate IEEE
