  • Patent number: 11964662
    Abstract: A method for allocating power between electric machines in a powertrain of an electric vehicle is described. The electric vehicle includes a gearbox having an input shaft and an output shaft configured to transmit a first torque to the wheels of the vehicle, a first electric machine having an output shaft coupled to the input shaft of the gearbox, and a second electric machine configured to supply a second torque to wheels of the vehicle. The method comprises: prior to a gear change of the first electric machine, allocating power to the first and second electric machines according to a first power ratio; in response of an intended gear change of the first electric machine, allocating power to the first and second electric machines according to a second power ratio.

  • Publication number: 20240100957
    Abstract: A method of open loop control of a retardation torque of a vehicle is presented. The method comprises obtaining of a current vehicle acceleration indicator, obtaining of one or more current vehicle state indicators, and determining of an open loop retardation torque based on the vehicle acceleration indicator and the one or more vehicle state indicators. The method further comprises controlling of a resulting retardation torque based on the open loop retardation torque. The resulting retardation torque is applied by one or more propulsion sources of the vehicle.

  • Publication number: 20240100958
    Abstract: A method includes i) receiving, by a processor device of a computer system, a signal corresponding to a release of an accelerator, ii) receiving, by the processor device, a signal corresponding to a first tap on a brake pedal, said first tap comprising an initiated physical interaction with the brake pedal and a subsequent release of the physical interaction with the brake pedal, iii) determining, by the processor device, a second braking torque, iv) applying the second braking torque as a response to the first tap on the brake pedal, and maintaining the applied braking torque after said tap on the brake pedal.

  • Publication number: 20240101101
    Abstract: An energy management system (EMS) comprising a control unit for controlling charging of an energy storage system (ESS). The control unit is configured to obtain, from the ESS, a parameter representing a charge ability (P/Ic) of the ESS and a parameter representing an actual charging power (P/Ia) measured by the ESS; compare the actual charging power or current (P/Ia) with a current value of the charge ability (P/Ic); adjust the current value of charge ability (P/Ic) based on the comparing result; and provide the adjusted value of charge ability (P/Ic,adj) to a power-to-mechanical conversion unit for generating one or more control signals based on the adjusted value of charge ability (P/Ic,adj) for controlling charging power delivered by one or more electric machines.
