摘要： The present invention presents a method and a system for the control of preparatory measures during a road section, for at least one system. First, one or several parts of a road section are identified, during which parts one or several engines comprised in the vehicle may be shut down. Such identification is carried out when the road section is ahead of the vehicle, that is to say before the vehicle has entered the road section. The identification is based on available information about the road section. Subsequently it is determined whether at least one preparatory measure for at least one respective system in the vehicle needs to be carried out, in order to facilitate that one or several of the engines may be shut down. Subsequently, the preparatory measures are controlled based on the determination of the need to carry out the at least one preparatory measure.

摘要： A method and a system for choosing a transmission mode in a vehicle over the course of a road section, wherein the vehicle has applied coasting prior to this road section and wherein a highest permitted speed vmax is defined for the road section, below which an actual speed for the vehicle should be kept. A simulation of a future speed profile vsim_Gear for a possible gear position for a gearbox in the vehicle is conducted on the basis of a road slope obtained from map data in combination with vehicle positioning information and wherein the simulation simulates, when the road section lies ahead of the vehicle, an actual speed for the vehicle over the course of the road section. Next, an evaluation is carried out of whether a suspension of the coasting in favor of the possible gear position is recommended, wherein the possible gear position is deemed recommendable if a highest value vsim_Gear_max for the future speed profile exceeds the highest permitted speed vmax. The evaluation is then utilized in the choice of transmission mode.

摘要： A method, performed by a control device, for starting a combustion engine during free-wheeling with engine off is described. The method comprises a step of controlling the clutch to a partially closed state, thereby starting the combustion engine; a step of controlling the clutch to an open state when the combustion engine has started, but prior to the output shaft of the combustion engine has reached a rotational speed synchronized with the rotational speed of the input shaft of the gearbox; and a step of synchronizing the speed of the combustion engine to the speed of the input shaft of the gearbox through control of fuel injection to the combustion engine.

摘要： A system for control of temperature for a vehicle exhaust treatment system comprising a first determination unit arranged for determination of a temperature for the exhaust treatment system, and a simulation unit arranged for simulation of a future velocity profile, based on information relating to a road section. A second determination unit arranged for determination, based on a future velocity profile, of whether a simulated active brake process due to an over-speed for the vehicle will occur within the road section. A utilization unit is arranged for utilization, if the at least one temperature for the exhaust treatment system is below a minimum temperature threshold value, and if the simulated active brake process is simulated to occur within the road section, of an engine fitted auxiliary brake, which is fitted in connection with an exhaust stream from an engine in the vehicle, where the utilization is initiated before over-speed occurs.
