Plug-in Hybrid Fuel Consumption Can Be Cut By 10% Via Logged Driving Routes

The fuel consumption of plug-in hybrid electric vehicles (PHEVs) can be cut by as much as 10% (for long-distance driving) through the use of logged driving routes, according to new research from the Chalmers University of Technology.

Scientists at Chalmers University of Technology have come up with a method to automatically identify recurrent travel routes from logged driving data and compute optimal control rules for these. Moreover, Viktor Larsson has developed methods to make the calculations more efficient in terms of computation time and memory. The strategy can reduce fuel consumption by up to 10% compared to conventional methods. Image Credit: Volvo Car Corporation

By scheduling the use of the battery for specific portions of a journey, fuel consumption can be decreased considerably (for some trips) — but in order to do this, the car needs to “remember” the routes commonly used.

Enter the new research — a new method has been developed that allows a vehicle to identify “recurrent routes and pre-compute when the battery should be used, and when running the car on petrol is more energy efficient.”
