The data is collected by the user reading the data on the phone via bluetooth, approaching the car with the phone or entering the car with the activated bluetooth connection, launching the application and starting the synchronization of the data that is automatically loaded into the phone.

By selecting the period from the calendar for which he wants to view the data, he can simply compare and get an overview of where and what he can change in the driving style.

The device reads data from the car in real time and generates new data based on this data:

• Mileage with an accuracy of 1.06% to 3%

• Speed

• Rpm

• Predicts the state of the battery based on the measured value of voltage and voltage drop per unit time

• Registers sudden braking

• Driving style

• Time and date of start and end of each ride

• Number of brakes (speed change of 10km / h for 2 sec, without increasing speed)

• Service intervals, small and large service based on mileage and driving style

• Predicts on the basis of kilometers traveled, type of driving, city – highway intervals for changing tires

• Engine faults according to OBD2 standard (further development on UUDS unified diagnostic services, WWH)

The device is universal, provides the same functionality for all cars, does not depend on the car manufacturer. Autonomous operation, does not require a permanently connected phone, does not depend on the smartphone’s operating system.
