drivetrain is just that the powertrain includes all the drivetrain components
and includes the power
source components such as engine and wheels.
The
Drivetrain
changes depending on the type of the vehicle such as Front-wheel, Rear-wheel or Four-
wheel drive
etc
. or on the type of the power source such
as for electric vehicles, hybrid electric vehicle,
Hydraulic hybrid vehicles etc. The hybrid electric vehicle Powertrain has more no of components and
more complexity than a simple ICE Powertrain due more electrification. In HEV powertrain, electrical
energy is also used as along with engine to produce torque, so the drive train are designed in such a way
that the torque of both sources is combined and distributed to the wheels. And the drivetrain uses the
power control units to control or stop the power from the engine or electric motor.
Basically, the HEV drivetrain consists of ICE, Electric motor, Battery, energy convertor, Transmission
and Power Control Unit (PCU). The HEV drives their wheels on two power source ICE and Electric
Motor which are connected to Transmission which are connected to the axle and then to the wheels. The
Electric Motor is powered by battery, it is connected to the DC-DC convertor to converts the voltage of
the current flowing through it and supply it to the motor. The power sources are controlled by power
management unit which commands the sources to switch On/Off according to the performance required
and optimization of the vehicle.
The HEV has Power Management unit or Power Control Unit which is built with control strategy
