摘要： The method and a control unit for controlling a regenerative brake system in a vehicle for which there is a defined maximum speed v max which the vehicle should not exceed are presented. According to the present invention at least one predicted speed v pred for the vehicle on a section of road is determined. If the at least one predicted speed v pred exceeds the maximum speed v max along the section of road, the regenerative brake system is then activated before an actual speed v act of the vehicle reaches the maximum speed v max . The result is braking over more time and with less power than in previous known solutions, making it possible for the regenerative brake system to utilise more of the brake energy than in previous known systems.

摘要： 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.

摘要： The present invention relates to a method and a system arranged for the control of a combustion engine in a vehicle. According to the invention, at least one future speed profile v Sim coast for an actual speed v act of the vehicle during a road section is simulated. The simulation is based on information about the road section, and assumes that coasting will at least partly be applied during the road section. Subsequently, an applicability for coasting during the road section is evaluated. Subsequently, it is evaluated whether the combustion engine may be shut down during a coasting for at least a part of the road section that is deemed applicable. The evaluation of the shutdown of the combustion engine is here based at least on whether one or several system conditions for engine shutdown have been met, on one or several properties for one or several brake systems in the vehicle, and on a shutdown period T ICE_off , when the combustion engine could be shut down. The combustion engine is then controlled based on this evaluation of turning off the engine.

摘要： 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.
