  • Publication number: 20240308511
    Abstract: A method is provided for controlling a speed of a vehicle using a Pulse and Glide (PnG) operation whereby the speed of the vehicle is controlled 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. When the PnG operation is being carried out and a speed reduction operation is commenced to decrease the speed lower than the reference speed, the method comprises adjusting the PnG operation such that the speed reduction to the decreased speed is carried out immediately following a speed increase in the pulse-phase to at least the first speed, wherein no propulsive torque is applied during the speed decrease.

  • Publication number: 20240217516
    Abstract: A system for braking a vehicle is provided. The system comprises a powertrain comprising an electric machine arranged to propel the vehicle and a transmission arranged to transfer power between the electric machine and the driving wheels of the vehicle. The system further comprises a resistor device arranged to dissipate electric energy generated by the electric machine during braking of the vehicle, and an airflow generating device arranged to generate an airflow over the resistor device. The airflow generating device is arranged to be mechanically driven by the powertrain so as to generate said airflow. By (mechanically) driving the airflow generating device by means of the powertrain, the airflow generating device does not need its own motor, thereby making the system less complex. Further, the driving of the airflow generating device by means of the powertrain will consume energy itself, contributing to braking the vehicle.
