Look-ahead Control for Heavy Trucks to minimize Trip Time and Fuel Consumption
The scenario studied is a drive mission for a heavy diesel
truck. With aid of an on board road slope database in combination with
a GPS unit, information about the road geometry ahead is
extracted. This look-ahead information is used in an optimization of
the velocity trajectory with respect to a criterion formulation that
weighs trip time and fuel consumption. A dynamic programming algorithm
is devised and used in a predictive control scheme by constantly
feeding the conventional cruise controller with new set points. The
algorithm is evaluated with a real truck on a highway, and the
experimental results show that the fuel consumption is significantly
reduced.
