Again, that would be great, because, first - I'm not a good writer (I used to live-write fairy tales over ICQ back in days, however...), and second - that would mean less work for me.
I will explain values that are shown in the system below. Tell me if I got too technical here, cos' this is how I intend to describe them in the readme. Description assumes you were using one file and app was running all the time.
Right column (direct values):
- Engine running time is the time engine was working.
- Engine running time, idling - is time your engine was working and you were not pressing the accelerator, but engine was using fuel.
- Total fuel consumption is all the fuel consumed.
- Fuel consumed per hour is total fuel consumed, divided by engine running time. You want this to go down.
- Distance with trailer - total distance you covered with trailer attached.
- Transport work is how far you moved how much cargo. It's tonnes multiplied by kilometers.
- Average weight is average weight of your deliveries. Calculated as transport work divided by distance with trailer.
- Max. vehicle/engine speed is your "records" - you really want them to be reasonable.
- Distance with cruise control is how much you drove with CC on.
- Coasting distance is how much you drove while not pressing the throttle, i.e. downhill.
- Brake applications is how many times you pressed the brake pedal.
- Harsh b.a. is how many times you braked long enough to lose more than 3200 (km/h squared). I did this to be fair to keyboard users, who I am. You can't brake partly on keyboard, you press the pedal to the metal. But if you lost that much energy - it's a harsh braking.
Left column (calculated values):
- Transport work, average - measures how much work you did per liter of fuel. You want this to go up. It won't go up if you use strong truck and light cargoes.
- Avg. fuel consumption is how much fuel you spend per 100km of road. You want it to go down.
- Idling % - how much time your engine spent idling (look above) out of all working time. You want it to go down. Advice - turn engine off at traffic lights, don't coast in neutral.
- Engine overspeed % - time your engine spent near it's RPM limit, within 100 RPM to be exact. You don't want this at all.
- Speeding % - is time you accelerated while being more than 5 km/h over the speed limit. I.e. intentionally speeding. 5km/h buffer is because in England city speed limit is 48, and CC jumps from 45 to 50. Normally you don't want that, large speeds are bad for fuel.
- Driving outside optimum engine speed band - time your engine was driving the truck outside 900-1600 RPM range, which is optimum for most of diesel engines. Does not count coasting and engine braking, does not count speeds below 10 km/h. You normally don't want that.
- Brake apps #/100km is how much per 100 km you pressed the brake pedal. You want this to go down.
- Harsh b.a. #/100km - same for harsh braking.
- Harsh accelerations #/100km - same for aggressive accelerations. Starts counting when your truck exceeds 1600 rpm with throttle over 70%, stops when you release the throttle, counts if you gained over 3200 (km/h squared) during that period. Again, made for keyboard users.
- Coasting % - important metric. Measures how much distance you covered coasting with no throttle, out of total distance covered. You want this to be over 20%, the more - the better. This accounts for a lot of things, all coming down to using the momentum of your truck. I can write a separate post about it, but you can go, for example, to Scania's website and read about Opticruise and driver assistance.
- Driving with vehicle warning - is how much distance you covered with over 15% damage to your truck. You normally don't want this at all. Maintain your truck and avoid collisions.
- Driver support (Avg. score in %) - TBD, when I obtain a full manual to one of the driver support systems.
