<p>The present invention relates to a method and system for controlling the operation of a vehicle. The look-ahead cruise control function according to the invention identifies (25) a set of points of each important, i.e. steeper, ascent and descent along the route of said vehicle, the route being stored in a road map, wherein each point being associated with at least one vehicle operation criterion; calculates (26) the specific position of each of said points based on a plurality of vehicle parameters, vehicle operation parameters including at least vehicle position relative said road map and vehicle speed, and road route parameters of the road map; stores (27) the calculated positions; obtains (28) present vehicle position in order to determine the vehicle position relatively the road map; selects (29) a driving strategy instruction for the control of said vehicle for each distance between the calculated positions for two consecutive points of each ascent and descent based on said vehicle position, and controls (30) at least one engine operating parameter as a function of said driving strategy instruction between each of said consecutive points in order to control the vehicle operation such that said at least one vehicle operation criterion associated with respective point of each of said points is fulfilled. The invention further relates to a computer program (24) for an electronic control unit (8) of a vehicle, a computer program (24) stored on said computer readable medium (22), and an electronic control unit (8).</p> |
