METHOD AND CONTROL ARRANGEMENT FOR CONTROLLING A SPEED OF A VEHICLE PERFORMING A PULSE AND GLIDE OPERATION

A method performed by a control arrangement for controlling a speed of a vehicle, the vehicle being configured for carrying out a Pulse and Glide (PnG) operation, the PnG operation controlling the speed of a vehicle about a reference speed. The PnG operation comprises a pulse-phase during which the...

description A method performed by a control arrangement for controlling a speed of a vehicle, the vehicle being configured for carrying out a Pulse and Glide (PnG) operation, the PnG operation controlling the speed of a vehicle about a reference speed. The PnG operation comprises a pulse-phase during which the speed of the vehicle is increased to a first speed, higher than the reference speed, followed by a glide-phase during which the speed of the vehicle is allowed to decrease to a second speed, lower than the reference speed. The method is performed when the PnG operation is to be carried out and when a speed increase to an increased speed, higher than the reference speed, is to be commenced during the PnG operation. The method comprises adjusting the PnG operation such that the speed increase to the increased speed, is carried out by accelerating the vehicle immediately following a speed decrease in the glide-phase to at least the second speed.Hereby, increased energy efficiency may be obtained by increased use of PnG operation. Moreover, risk of jerky movements of the vehicle may be reduced and the driving comfort increased.
