Abstract: Method and system for controlling a cruise control and a transmission in a vehicle over the course of a road section, wherein said vehicle, prior to said road section, has applied coasting and utilizes said cruise control. According to the present invention, a reference speed v ref utilized in said cruise control during said coasting is lowered to a lowest permitted speed v min defined for the road section if said lowering is deemed applicable. A comparison of a drive force F dd requested from an engine system in the vehicle with a threshold value F lim for said drive force is also carried out. The coasting is then suspended if said requested drive force F dd exceeds said threshold value F lim for said drive force.

Abstract: The present invention relates to a method and a system for control of a cruise control, which cruise control supplies a reference speed v ref for control of a propulsion system. The reference speed v ref is here based on a set speed v set chosen by a driver of a vehicle which is provided with the propulsion system, and it is possible for said cruise control to allow deviation between the reference speed v ref and the set speed v set . The present invention detects whether there is at least one particular driving situation, this detection being based on how the driver acts when the vehicle is in motion. If there is at least one particular driving situation, a first limitation of the permissible deviation is applied during the at least one particular driving situation. According to the invention, a second limitation of the permissible deviation is also applied during a period of time T A after the end of the at least one particular driving situation.

Abstract: The present invention relates to a system for handling of errors in map data D map . According to the invention information I related to map data D map is determined by a determination unit. An identification unit then makes an identification of at least one error in said map data D map on the basis of said information I determined. Thereafter a storage unit stores data D related to said at least one error identified in map data D map . A providing unit can then at least partly disregard said map data D map comprising said at least one identified error, when supplying map data D map , so that said stored data D may instead be used in decision making. The risk of decisions being taken on the basis of erroneous map data D map may thus be minimised.
