    摘要: A method to control an output voltage of a DC-DC converter, and voltage control logic operable to generate a voltage command to implement the control method, the method including sensing a voltage of a bus of an electric-drive vehicle; increasing a command voltage signal from the sensed voltage to a nominal voltage during a first time period; increasing the command voltage signal from the nominal voltage to a desired voltage during a second time period greater than the first time period; and generating a voltage output based on the command voltage signal.

    摘要: A method of controlling a vehicle accessory includes determining a transmission of a vehicle is in a non-park setting; in response to determining the transmission of the vehicle is in the non-park setting, receiving speed data indicative of a speed of the vehicle; determining a speed to operate the vehicle accessory based on the vehicle speed; comparing the determined speed to operate the vehicle accessory to a speed threshold; and in response to determining that the determined speed is below the speed threshold, providing a command to the vehicle accessory to one of deactivate the vehicle accessory or operate the vehicle accessory at a reduced operating state relative to a current operating state of the vehicle accessory.

    摘要: A method of controlling electrically-powered vehicle accessories includes receiving energy data, the energy data providing an indication of an availability of free energy; receiving an electrically-powered vehicle accessory classification for an electrically-powered vehicle accessory, the classification including one of a critical and a discretionary electrically-powered vehicle accessory; receiving a prioritization for the electrically-powered vehicle accessory based on the classification and whether the electrically-powered vehicle accessory has an energy storage component; and providing a command to control energy consumption by the electrically-powered vehicle accessory based on its prioritization and the availability of free energy.
