摘要： A system and method for controlling an AC motor drive includes a control system programmed with an energy algorithm configured to optimize operation of the motor drive. Specifically, the control system receives input of an initial voltage-frequency command to the AC motor drive, receives a real-time output of the AC motor drive generated according to the initial voltage-frequency command, and determines a real-time value of a motor parameter based on the real-time output of the AC motor drive. The control system also inputs a plurality of modified voltage-frequency commands to the AC motor drive, determines the real-time value of the motor parameter corresponding to each of the plurality of modified voltage-frequency commands, and identifies an optimal value of the motor parameter based on the real-time values of the motor parameter. The control system maintains an input of a current modified voltage-frequency command when the real-time value of the motor parameter corresponds to the optimal value of the motor parameter.

摘要： An indicator unit is provided to display information to occupants in a motor vehicle. The indicator unit is adapted for connection to a communication network and intercepts messages that carry data between other vehicle equipment. A control circuit is programmed to identify the existing network messages that carry the data needed for the information display. The control circuit operates a display device in response to received data. Because the indicator eavesdrops on the network and intercepts existing data messages, other equipment in the motor vehicle do not have to be programmed to communicate specifically with the indicator. This facilitates adding specific indicators to a particular truck.

摘要： A system and method for controlling an AC motor drive includes a control system programmed with an algorithm configured to optimize operation of the motor drive. Specifically, the control system is programmed to input an initial voltage-frequency command to the drive. The initial voltage-frequency command includes a voltage reference and a frequency reference corresponding to an operating point of an initial voltage/frequency (V/Hz) curve. The control system monitors a real-time output of the drive, modifies the voltage reference based on the real-time output of the drive, and transmits a modified voltage-frequency command to the drive. The modified voltage-frequency command corresponds to an operating point of a modified V/Hz curve defined by the modified voltage reference and the initial V/Hz curve.
