High Voltage Systems - Aston Martin VALKYRIE 2021 Manual

High Voltage Systems

This vehicle is a parallel hybrid vehicle. This means that drive is
provided by both a traditional internal combustion engine and
high voltage electric motor, both of which are connected directly
to the transmission.
The electric motor is between the engine and gearbox and is also
used as a generator, transmission gear synchronisation, reverse
gear and pull away. As a high voltage system is also available, the
air conditioning compressor, cabin heater are electrically
operated rather than engine driven. The power steering pump is
also electrically driven rather than engine driven.
E-Motor
This vehicle features an electric motor that is used to perform
multiple functions on the vehicle to improve performance and
reduce engine load.
Starter Motor
The electric motor itself is used as the starter motor for the
engine. When the engine is first started, this will also synchronise
the engine, electric motor and transmission.
Initial Pull Away
To allow for smoother pull offs, the electric motor allows the
vehicle to move from a stop in first gear up to speeds of 10-15
km/h (6-10 mph) before the clutch is engaged and engine power
applied.
Reverse Gear
The transmission itself does not contain a traditional physical
reverse gear. Instead, first gear is selected and the electric motor
is run backwards to achieve reverse.
Transmission Synchronisation
The electric motor is used to synchronise the speed of the
transmission input shaft to the engine speed.
