Abstract
Methods and systems are provided for a turbocharger. In one example, a method includes adjusting one or more of a wastegate position and a position of vanes with operation of a turbocharger to reach a desired turbocharger speed via a controller. The method further includes adjusting engine operating parameters to reach the desired turbocharger speed.
Claims15
A system, comprising:
- a turbocharger comprising a turbine wheel, wastegate and an electric motor, the turbocharger being couplable to an engine configured to produce power, wherein the turbine wheel comprises a plurality of vanes coupled to a nozzle ring, and wherein the plurality of vanes is pivotably adjustable, between a fully open position and a fully closed position, along a central axis relative to the nozzle ring;
- and
- a controller comprising a non-transitory memory unit, configured to store instructions thereon, when executed cause the controller to:
- detect a wheel slip of an axle of a vehicle that is driven by the power produced by the engine;
- adjust operation of the turbocharger responsive to the wheel slip being detected, wherein the adjusted operation of the turbocharger comprises, when the wheel slip of the axle is detected, adjusting a wastegate position of the wastegate and pivotably adjusting the plurality of vanes relative to the nozzle ring until the wheel slip of the axle is less than a threshold percentage of wheel slip.
2 more elements
A method comprising:
- detecting a wheel slip of an axle of a vehicle having plural axles, the vehicle comprising an engine with an alternator, and a turbocharger with an electric motor and a wastegate, wherein the turbocharger comprises a turbine wheel further comprising a plurality of vanes coupled to a nozzle ring, and wherein the plurality of vanes is pivotably adjustable, between a fully open position and a fully closed position, along a central axis relative to the nozzle ring;
- and
- adjusting operation of the turbocharger responsive to the wheel slip being detected, wherein the adjusted operation of the turbocharger comprises, when the wheel slip of the axle is detected, adjusting a wastegate position of the wastegate and pivotably adjusting the plurality of vanes relative to the nozzle ring until the wheel slip of the axle is less than a threshold percentage of wheel slip.
