    摘要: A memory management method including the steps of storing a value and writing data. The storing a value step stores a value representative of a number of erase/write cycles that a subset of memory space of a first memory has undergone. The first memory having an assigned predetermined maximum number of erase/write cycles. The writing data step writes data to the subset of memory space dependent upon whether the value is below the predetermined maximum number.

    摘要: Embodiments of the present invention provide a device and method for generating initial operating points for controlling an interior permanent magnet (IPM) machine. The method includes loading an inductance lookup table, first calculating a maximum torque per Ampere (MTPA) trajectory for a first threshold speed based on machine parameters of the IPM machine, second calculating a truncated voltage limit ellipse with monotonically increasing torque for a first speed based on the machine parameters, if the first speed is higher than the first threshold speed, determining an operating trajectory at the first speed based on at least one of the calculated MTPA trajectory and the calculated truncated voltage limit ellipse, and generating an Id,Iq map that maps an Id value and an Iq value to each torque command of a plurality of torque commands for the first speed based on the determined operating trajectory.

    摘要: An electric drive system comprises a generator, a traction motor, a brake resistor, a bus, and a control unit. The generator, the traction motor, and the brake resistor are coupled electrically to the bus. The control unit is configured to determine a pulse-width-modulation duty cycle for the brake resistor (“brake duty”) and control operation of the brake resistor according to the brake duty, wherein the brake duty can be a value intermediate of constant OFF and constant ON. A method of operating the electric drive system is also disclosed.
