Test Function No. 12 - Average Speed for Arrival Time Calculation

• This function is locked and needs to be unlocked via the procedure in Function Test No. 19. The following data can be scrolled through using the trip reset button. This function shows the average speed used for calculation of the arrival time and also the momentary arrival time value.
  • 'VANK: 136.5 km/h' - this shows the average speed used for arrival time calculation.
  • 'ANK: 23:46' - this shows the momentary arrival time.

The calculation of average speed uses signals from the ABS ECU for speed and distance to produce the average speed value. After the system is reset, a default average value of 40 km/h is used, until the vehicle is moving again with the engine running. When the vehicle is stationary, with the engine running, the calculation of average speed is interrupted. The arrival time is adjusted by monitoring the clock. Every full minute that passes on the clock, with the vehicle stationary, is added to the arrival time.
