  • Publication number: 20250219565
    Abstract: A method for actuating a vehicle drive. If a fault occurs in the electric drive or in a component connected thereto, the inverter generates an AKS state in the form of an active short circuit of phase connections of the electric machine, or a freewheeling state of the electric machine. Once the fault has occurred, steps AKS and F are executed alternately. Step AKS: setting the AKS state if a phase current flowing through the phase connections is below a first current limit and changing over to step F if the phase current reaches the first current limit; Step F: setting the freewheeling state if a DC voltage generated by the electric machine is below a first voltage limit and changing over to step AKS if the DC voltage is above the first voltage limit. A changeover from step AKS to step F if the phase current reaches a second current limit below the first current limit. A changeover from step F to step AKS if the DC voltage reaches a second voltage limit below the first voltage limit.

  • Publication number: 20250192712
    Abstract: A method for controlling a multi-phase traction inverter having the following steps is described. It is determined whether the condition that an electrical frequency of the output signal of the traction inverter is below a predefined limit is met. If the condition is met, that phase of the traction inverter which carries the highest current load among all the phases of the traction inverter is ascertained. A duty cycle offset of this phase with respect to a duty cycle of 50% is ascertained. The duty cycle offset of this phase is then changed by changing the duty cycle of this phase by a duty cycle change. Finally, the duty cycles of the other phases of the traction inverter are adapted by also changing their duty cycles by the duty cycle change. Furthermore, a traction inverter having a control unit which implements the method is described.

  • Patent number: 12296814
    Abstract: The disclosure relates to a method for distributing torque in the event of a load change for a motor vehicle. The motor vehicle has a first torque source that provide a first torque, and a traction motor that provides second torque. After determining that the torque distribution should be changed, the first torque is reduced, with a first gradient, from the positive torque range to a torque neutrality. At a specified load change time before the torque neutrality of the first torque is reached, the second torque of the traction motor is adjusted into the negative torque range with a specified second gradient until a predetermined load change range of the traction motor has been traversed. After the load change range has been traversed, the second torque is taken further into the negative torque range with a third gradient. The third gradient being steeper than the second gradient.

  • Patent number: 12301038
    Abstract: The disclosure provides a device for operating an electronic system. The device includes a power supply unit that, during operation, provides a supply voltage on a supply potential output. The power supply unit has an enable input via which the supply voltage can be enabled and disabled by an enable signal. In a power-latch phase of the electronic system in which the enable signal is not present, the power supply unit provides the supply voltage upon receiving a trigger signal even when the enable signal is not present. The device includes a microcontroller supplied with the supply voltage on a second supply potential input connection when the enable signal is present or when the microcontroller, in the power-latch phase, generates the trigger signal and transmits it to the trigger signal input. Upon receiving a control command, the power supply unit suppresses deactivation of the supply voltage for supplying the microcontroller.
