Abstract: A method for controlling a vehicle's speed by adopting a desired speed vset for the vehicle; determining a horizon for the intended itinerary made up of route segments, effecting the following during each of a number of simulation cycles (s) each comprising a number N of simulation steps conducted at a predetermined frequency f: first predicting the vehicle's speed vpred—cc along the horizon with conventional cruise control when vset is presented as reference speed, comparing the predicted vehicle speed vpred—cc in a range vmin to vmax, making a second prediction of the vehicle's speed vpred—Tnew along the horizon based on the vehicle's engine torque T; determining a reference value for how the vehicle's speed is to be influenced on the basis of at least one of the comparisons and the predicted vehicle speed vpred—Tnew; controlling the vehicle by the reference value. A module for the foregoing controls a vehicle's speed.

Abstract: A reference value for controlling a vehicle's speed is obtained by: receiving a choice from two selectable driving modes, each driving mode having a unique set of settings that influence the calculation of the reference value; making a first prediction, based on an engine torque Tret that retards the vehicle as compared with conventional cruise control, and a second prediction based on an engine torque Tacc that accelerates the vehicle as compared with conventional cruise control; comparing the first and second predictions with a lower limit value and/or an upper limit value, which delineate a speed range within which the speed should be; and determining the reference value based on the mode choice and on at least one of the comparisons and said first prediction and second prediction of the speed along the horizon, such that the reference value is within the speed range.

Abstract: A method for controlling a vehicle's speed, including: acquiring a set speed; determining, using using map and location data, a horizon made of route segments, each with a route characteristic; performing simulation cycles, each including: predicting the speed according to a conventional cruise control, which first prediction depends on the route characteristic; comparing the first predicted speed with lower and upper limit values, which define an engine torque for use in the next simulation cycle; making a second prediction of the speed when the engine torque depends on the comparison in the immediately preceding simulation cycle; comparing, as a second comparison, the second predicted speed with second lower and upper limit values, which delineate a speed range within which the speed is maintained; determining, based on the second comparison and/or the second predicted speed in this simulation cycle, a reference value for use by a vehicle control system.

Abstract: A system having a user interface which presents map data Dmap. An analysis unit analyzes map data Dmap, determining a quality Q for these map data Dmap which are to be presented. The determination is based on whether the respective map data Dmap are available and/or reliable. The quality Q is presented graphically by a presentation unit. The risk of wrong decisions being taken on the basis of deficient map data Dmap is reduced considerably, since the user can easily decide whether there are reliable map data or not.

Abstract: A system for handling errors in map data Dmap. Information I related to map data Dmap is determined by a determination unit. An identification unit then identifies at least one error in the map data Dmap on the basis of the information I determined. Thereafter a storage unit stores data D related to the at least one error identified in map data Dmap. A data providing unit can then at least partly disregard the map data Dmap including the error, when supplying map data Dmap, so that the stored data D may instead be used in decision making. The risk of decisions being based on erroneous map data Dmap may thus be minimized.

Abstract: A method for an economical cruise control and an economical cruise control which demands from a vehicle engine system a reference speed vref, which may differ from a chosen set speed vset. Adjustment of at least the set speed vset is allowed when the reference speed vref differs from the set speed vset. The adjustment is based at least partly on input from a user of the economical cruise control. A user of the economical cruise control is thus provided with an increased feeling of control over the vehicle's speed.

Adjustment of at least the set speed vset is allowed if the reference speed vref differs from the set speed vset, which adjustment is based at least partly on a current speed vpres of the vehicle and on input from a user of the reference-speed-regulating cruise control. Quick and simple user-controlled adjustment of the set speed vset is thus achieved.
