PROBLEM TO BE SOLVED: To provide a vehicle operation recording device capable of being used in common for on-vehicle speed sensors even when the on-vehicle speed sensors are different from each other in the number of pulses generated.SOLUTION: A vehicle operation recording device 1 is provided which calculates vehicle running speed V at predetermined time intervals based on an output signal H of an on-vehicle speed sensor VS, and records the calculated running speed with respect to time. The vehicle operation recording device 1 includes recognition means for recognizing the number of generated pulse n for one rotation of a drive shaft of the on-vehicle speed sensor. The recognition means includes a position sensor 11 for acquiring a position signal of the vehicle, a time sensor 12 for acquiring a time signal, a frequency input part 13 for acquiring output signal frequency of the on-vehicle speed sensor, a speed measurement part 14 for measuring vehicle running speed based on the position signal by the position sensor and time signal by the time sensor, an identification part 15 for identifying the generated pulse number, by substituting the running speed measured by the speed measurement part and the output signal frequency input to the frequency input part to a relation expression of the output signal frequency, running speed, and generate pulse number, and a setting part 16 for setting the identified generated pulse number.
