Volvo's electric hybrid driveline reduces fuel consumption-
-by around 30 % compared with a traditional diesel engine.
Using Active Green Driving, which optimizes driveline characteristics-
-fuel consumption has been cut by a further 6-8 %.
It's very much about fuel economy, trying to reduce fuel consumption-
-and the emissions of the vehicle.
It's based on a normal hybrid electric vehicle-
-running in a city environment.
We're using a bus, but it's applicable to every kind of vehicle-
-running in the same route over and over again.
A city bus is a good example.
Active Green Driving is one of Volvo's contributions to HAVEit-
-an EU project aiming to develop a new generation of intelligent vehicles.
In this case, it's a question of utilizing the characteristics-
-of hybrid vehicles as effectively as possible.
One big advantage is that we can recover brake energy.
Then we can use the electric energy to propel the vehicle afterwards.
That's basically what has been done before in the hybrid driveline.
What's new now is that we know what will happen in the future.
We know in advance when we will brake the bus.
We're using two laser scanners.
This one and the one at the other end.
They are used for detecting vehicles-
-and different kind of objects that would make us slow down.
We're also using a colour camera.
It's used for detecting traffic lights-
-whether they are green or red-
-so we will know if the bus will have to stop.
A GPS system with programmed map data-
-shows the route and road characteristics.
Roundabouts, traffic lights, hills and planned stops.
Active Green Driving chooses the energy the vehicle will use in advance.
Electricity, diesel or both.
If we know that we're approaching a steep uphill-
-then we might want to save electric energy-
-to have some power to climb the uphill afterwards.
If we know that we will brake the vehicle quite soon-
-and hence be able to recuperate energy-
-then we don't want the battery to be full.
Then we will just waste the brake energy.
Within the framework of the project-
-the driver coaching test concept has also been developed.
It's a virtual driving coach that shows the driver-
-how to drive in a more fuel-efficient way.
A haptic accelerator pedal produces more resistance-
-if the driver drives too quickly.
And a monitor on the dashboard gives the driver tips-
-on how he or she should proceed.
The difference between a driver driving aggressively-
-and a driver using this system, and driving smoothly-
-could be as much as 20 %.
No date has been finalized for the market release of Active Green Driving.
However, it's already clear that the solution offers many benefits.
The biggest benefit is the fuel saving.
Reducing the emissions is also an important thing.
One third thing is that it's easy to use this system on another vehicle.
We could simply bring this system from the bus-
-to another kind of hybrid vehicle-
-without having to do so much additional work.
