Abstract
A computer system is provided. The computer system has processing circuitry to determine that zero torque is requested from an electrical machine of a vehicle drivetrain; determine a limited d current within an allowable d current interval, the limited d current being different from an optimum d current to obtain the zero torque request; and control the electrical machine based on the limited d current to obtain the zero torque request.
Claims15
A computer system comprising processing circuitry configured to:
- determine that zero torque is requested for an electrical machine of a vehicle drivetrain;
- determine a limited d current within an allowable d current interval, said limited d current being different from an optimum d current to obtain the zero torque request;
- and
- control the electrical machine based on the limited d current to obtain the zero torque request.

A computer-implemented method, comprising:
- determining, by processing circuitry of a computer system, that zero torque is requested for an electrical machine of a vehicle drivetrain;
- determining, by the processing circuitry, a limited d current within an allowable d current interval, said limited d current being different from an optimum d current to obtain the zero torque request;
- and
- controlling, by the processing circuitry, the electrical machine based on the limited d current to obtain the zero torque request.
