[Verison 1.01] Parallel Hybrid transmission Script (Based off of Allison Ep40)

Das Forum befindet sich im reduzierten Betrieb. Die Addon- und Supportforen bleiben weiterhin verfügbar.
Bitte beachte, dass OMSI nicht mehr weiterentwickelt wird. Ein Teil der Entwickler widmet sich inzwischen der Entwicklung eines neuen Simulators. Weitere Informationen zum LOTUS-Simulator findest Du hier.
Ein communitybetriebenes Nachfolge-Forum wird hier verlinkt, sobald es gegründet und bereit ist.

    Hybrid script:


    From 0-40 KPH, the torque converter has been replaced with an electric drive. The engine RPM does nothing, yet. In future versions, I will incorporate an battery and if the battery charge fells below and certain rate the engine rpms will build up the supplement the charge.


    From 40-80, the bus is in blended mode, both of the components operating together. If the bus is on low, then the electric will do much of the acceleration.


    80-up the bus is in mechanical mode.

    The download needs to be installed within the OMSI directory, or wherever OMSI is installed.


    Changelog:


    Change log Version 1.0
    -Added more realistic traction motors modes for both A and B.
    -Incorporated smaller engine (Man O824) to simulate additional fuel savings.
    -The engine rpm in mode A does play an vital role in the bus's acceleration.
    -Redid the transmission model.



    -todo list
    -Dynamic braking with exhaust braking
    -Battery simulated
    -introduce turbocharged Man D0834 to the bus

    Features

    • Incorporate some form of hybrid system. from 0-32 kph, the battery is controlling the acceleration. From 32 to 80, there's an blend between the two, and from 80 kph and upwards, the system is full mechanical. As it stands now, the bus is set on its lowest setting. In future versions will incorporate more settings into the mix as well.
    • add throttle regulating to simulate the smooth acceleration of an hybrid with 5 different performance settings.

    Hi krtz07,


    I tried the MAN Hybrid on Canterbury map, where there are bus bays. The MAN was in Reverse gear, but startred in the wrong direction.
    <----- Series hybrid Ikarus 260 from 1975..

    krtz07 are you from philadelphia?


    Yes.....

    Ehm I've got a question. What is this .? There's no bus ?!

    Looks like you have installed the mod into the wrong directory!! It needs to be installed into the /Vehicles/Man202/ directory.


    Simple fix.


    #1. open up windows explorer, run an search for MAN_D89_D28_Hybrid.bus once it has find the file, delete it.
    #2 open up the ZIP file, select all of the contents of the file, extract it within the /Vehicles/Man202/ directory.

    looks nice so far. would be great, if u can insert a special electric sound, like e-engines do, into the script.

    ;)

    Just updated the script, it is basically the same as before but an few more things.


    • Three performance settings, by default, the bus is set to 1. 1 is the economy setting. 2 is the medium setting which is normally used on hybrids and 3 is the high performance setting. To change the setting, in the script folder, open up the hybrid_drive.txt and look for hybrid_performance_setting.
    • When I mentioned gear, I do not mean physical gears but how OMSI tweaks it. Done some tweaking to the engine rpm in the first gear, it is based off of an similar system as the 2nd gear. Added an hybrid propulsion system to the 2nd gear. Faster acceleration is the result.
    • Used the default engine (D2566) as oppose to the D2866
    • CVT curve for Max engine RPM is set to where the horsepower is the highest. At 2100 rpm. Yes there is more torque at lower RPMs, but the torque multiplier does not support the additional torque.

    I have the same problem, but this doesn't fix it...

    :(


    No

    :bus:

    still...

    Zitat von Benedettini

    Same happens in other addon buses...SD202s have problems with scripted transmission addons...Normal ones show up, others are blank. No prob in SD200s


    Yes, you dump them into the wrong location which is why none of them will load up correctly. The script touches nothing outside of the engine and transmission and sounds. The buses should load up correctly. If you extract the file contents into the wrong location, the bus will load up blank with an error. you could also checkout the log file (logfile.txt) to determined why the bus is not loading up.


    Well just made an update to the script file, the bus can now reverse and also made some tweaks to the bus performance. Also change the setup of the download zip, the download zip file now has to be extracted within the OMSI directory or wherever OMSI is installed.

    I did four runs with the new transmission script last night and i must say it's an ease on the pedals, i now know why some drivers prefer Hybrid shifts than Diesel, have to keep pumping the gas to get the bus to stay rolling, with this you get the silent whirr of the electric motor then the Diesel engine kicks in then before you know it you're up to 50km/h and sometimes going faster than you need to but on braking, i've noticed there's no retarder.


    Krtz01 not sure if you've seen the Volvo B5L but that has a slow sort of car like gear change, but once in to second gear it's moving very fast. I do like the Hybrids, but you've got to add the engine stall if you can as all hybrids cut out the engine on idling and leave the electric motor running and when you move off it kicks in.

    .... all hybrids cut out the engine on idling and leave the electric motor running and when you move off it kicks in.

    ;)

    ....actually that is not correct. The Volvo hybrids do this, but the Dennis Enviro 400H does not. The diesel engine is always running, even on idle. Generally speaking there are 2 types of hybrid: ones like the Volvo (and also cars like the Toyota Prius) which mix a diesel powered traction, with direct electrical traction. (So in those types, like the Volvo), the diesel engine will cut out while the electric is giving traction, or during idle.


    But the 2nd type of Hybrid are those where the traction is always coming from the electric battery, and there is no direct drive from the diesel engine to the axle. (similar to a diesel electric locomotive). In these types, the battery will power the bus but charge is regularly needed so the diesel engine revs to charge the battery. But the diesel engine does not 'cut out' on these types. When it is not 'revving' to charge the battery, it idles. This is how the Dennis E400H works.
