Abstract: A method is provided for producing a smooth transition between overmodulation and six-step operation of a SVPWM-controlled 3-phase electric machine. In one aspect, the method predicts the PWM sample for which the control voltage vector will cross the middle of each SVPWM hexagon sector. Then, based on the current voltage angle and duty cycle, as well as on an estimated future voltage angle and duty cycle, an average duty cycle is calculated and inserted. In addition, a PWM carrier waveform is selected to ensure the PWM pulses applied to each period result in continuous switching states.

Abstract: The present invention relates to a freewheel arrangement (4) having a freewheel (2), which comprises a first running ring (44), a second running ring (46), at least one clamping element (26; 28) that is between the first and the second running ring (44, 46) and is movable between a coupling position and a release position, and an actuating element (42) for adjusting the at least one clamping element (26; 28), wherein the actuating element (42) can be arranged on the first running ring (44) and is movable relative to the first running ring (44). A friction device (52) for generating a frictional force acting on the actuating element (42) is provided, the frictional force counteracting a drive force acting on the first running ring (44) so as to move the actuating element (42) relative to the first running ring (44). The present invention furthermore relates to a drivetrain (82) having such a freewheel arrangement (4).

Abstract: A variable cam timing phaser includes a housing disposed about an axis and having an inner housing surface defining a housing interior. The variable cam timing phaser includes a rotor moveable between an advance position and a retard position. The rotor includes a hub and a vane, with the rotor and the housing defining a chamber. The vane further defines the chamber into an advance chamber and a retard chamber. The variable cam timing phaser also includes a control valve assembly including a valve housing and a control piston. The variable cam timing phaser also includes a chamber biasing assembly disposed in one of the advance and the retard chambers and configured to bias the rotor into a predetermined position between the advance and the retard positions. The chamber biasing assembly includes a chamber piston, a chamber biasing member, and a chamber check valve.

Abstract: An oil pressure actuated or torsion assisted phaser with a lock pin that has a position which shuts off communication between the advance and retard chambers and the front cam bearing and/or oil control valve, effectively acting as a shutoff valve and preventing leakage of oil from the advance and retard chambers. The prevention of leakage maintains oil in the phaser after engine shutdown. Additionally, by shutting off communication between the advance and retard chambers and the oil supply, the side load on the lock pin from the oil pressure torque on the rotor vanes during unlocking of the lock pin can be reduced or eliminated.

Abstract: A turbocharger actuator arrangement for a turbocharger includes a movable actuator operating lever, a control rod, and a wave spring. More specifically, the control rod is couplable to a setting element of the turbocharger and is connected to the actuator operating lever by means of a bolt such that the control rod is arranged to be rotatable relative to the actuator operating lever. The bolt extends from the actuator operating lever through an opening in an end region of the control rod and through the wave spring. As such, the control rod and the wave spring are arranged between the actuator operating lever and a bolt securing means, which is arranged at an end region of the bolt that is averted from the actuator operating lever.

Abstract: A system includes a divided volute turbocharger having variable turbine geometry. The turbocharger includes a turbine housing, first and second volutes separated by a wall having a first and second tongue, and a turbine housing outlet. The system also includes a turbine wheel disposed in the turbine housing and a vane ring disposed in the turbine housing between the turbine wheel and the volutes. The vane ring includes a plurality of rotatable vanes disposed on a vane ring surface of an annular disk in an asymmetric or asymmetric vane pattern that receives the turbine wheel therewithin and a pair of aerodynamic spacers spaced circumferentially outward of the plurality of vanes with each spacer positioned adjacent to a respective one tongue, with the spacers and vanes directing and controlling the flow of exhaust from the volutes into the turbine wheel with generally equal flow while significantly reducing HCF forcing function.

Abstract: A method includes determining a value of an operational motor current limit and setting a value of a startup current limit equal to a predetermined value in excess of the value of the operational motor current limit if a set of predetermined conditions is satisfied. The method includes determining that operation of the engine has been interrupted, operating the electric motor of the variable valve timing mechanism with a current having a magnitude that is less than or equal to the startup current limit after determining that operation of the engine has been interrupted, determining that operation of the engine has resumed, and operating the electric motor of the variable valve timing mechanism with a current having a magnitude that is less than or equal to the operational motor current limit after determining that operation of the engine has resumed.
