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 can be significantly reduced.
