Main Question or Discussion Point

Hi there,

I am simulating the hybrid transit bus,

Its max speed is at 60 kph, most speed used on road is below 20 kph (more than 60% of its total operation time)

The bus follows stop-and-go pattern almost all the time.

The bus is to be fuel cell/battery hybrid, therefore it uses an electric motor as a traction motor

I need to specify its transmission and not sure if whether I should go for

1. Manual transmission
2. Automatic transmission
3. CVT

For a transit bus, how do I determine what type of transmission it should be?

Also, some texts suggest that the traction motor is capable of achieving ideal torque curve therefore a SINGLE gear transmission would suit this. How's this?

Should I go for a single gear for simplicity or multigear? What is the advantage and disadvantage of single gear?


Thank you
