  • Publication number: 20140114553
    Abstract: A method for running of a vehicle having a combustion engine which can selectively be connected to a driveshaft (104, 105) for propulsion of the vehicle, the vehicle can be run in a first mode (M1) with the engine connected to the driveshaft (104, 105) and in which fuel supply to the engine is substantially shut off, in a second mode (M2) with the engine disconnected from the driveshaft (104, 105) and a third mode like the first mode, but with the fuel supply not cut off. On a downgrade, determining whether running in the first mode (M1) will result in a speed increase, and then running in the second mode (M2) if running it in the first mode (M1) would cause a speed increase.

  • Publication number: 20140114542
    Abstract: A method for running a vehicle (100) that includes a combustion engine (101) which can selectively be connected to a driveshaft (104, 105). When the vehicle (100) is in motion and is approaching a downgrade, determining whether the engine (101) can be disconnected from the driveshaft (104, 105) for at least a first period of time (T1), and disconnecting the driveshaft (104, 105) for at least the first period of time (T1); and the engine (101) also is switched off for the first period (T1). A system that performs the method and a vehicle that performs it are disclosed.

  • Publication number: 20140088847
    Abstract: A method for running a vehicle (100) that includes a combustion engine (101) which can selectively be connected to a driveshaft (104, 105) to deliver driving force to the driveshaft (104, 105) for propulsion of the vehicle (100). When the vehicle (100) is in motion, determining whether the vehicle (100) is approaching a downgrade and, when it is approaching the downgrade, disconnecting the engine (101) from the driveshaft (104, 105) before the vehicle (100) reaches the downgrade. Also a system and a vehicle are disclosed.

  • Publication number: 20140074371
    Abstract: A method for operation of a reference-speed-regulating cruise control and a reference-speed-regulating 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 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.

  • Patent number: 8620558
    Abstract: A method for regulating a vehicle's speed including the steps of: determining a horizon by means of position data and map data of an itinerary made up of route segments with length and gradient characteristics for each segment; calculating threshold values for the gradient of segments according to one or more vehicle-specific values, which threshold values serve as boundaries for assigning segments to various categories; comparing the gradient of each segment with the threshold values and placing each segment within the horizon in a category according to the results of the comparisons; and, for each segment within the horizon which is in a category indicating a steep upgrade or a steep downgrade, calculating the vehicle's final speed vend after the end of the segment, based inter alia on the entry speed vi to the segment; and determining the entry speed vi for said segment based on the calculated final speed vend for the segment, which determination is defined by rules for said segment's category, so that the

  • Publication number: 20130151106
    Abstract: A method for controlling a vehicle's speed includes adopting a desired speed vset for the vehicle; determining by means of map data and location data a horizon for the intended itinerary which is made up of route segments with at least one characteristic for each segment; 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: making a first prediction of the vehicle's speed vpred—cc along the horizon with conventional cruise control when vset is presented as reference speed, which prediction depends on the characteristics of said segment; comparing the predicted vehicle speed vpred—cc with vmin and vmax, which demarcate a range within which the vehicle's speed is intended to be; making a second prediction of the vehicle's speed vpred—Tnew along the horizon when the vehicle's engine torque T is a value which depends on the result of said comparison in the latest preceding simulation cycle (s?1); determini

  • Publication number: 20130103258
    Abstract: Disclosed is a cost function that depends on at least a first term and a second term which have a mutual relationship between them. The cost function is also so configured that it is easy to expand to cover one or more further terms. The cost function is created such that when it is expanded to depend on the first term, the second term and at least one further term the cost function still maintains the same mutual relationship between the first term and the second term. The cost function also indicates a mutual relationship between the at least one further term and the first and second terms.
