Abstract
A hybrid electric vehicle (HEV) includes an internal combustion engine, an electric traction motor, a belt starter generator (BSG) unit, a low voltage battery system including a low voltage battery, and a high voltage battery system including a high voltage traction battery. A DC/DC converter is configured to convert high voltage from the high voltage battery system into low voltage to charge the low voltage battery and support low voltage loads. A powertrain control system configured for reducing HEV CO2 emissions includes a controller configured to control an output voltage setpoint of the DC/DC converter and the BSG unit. The controller is configured to selectively increase or decrease the output voltage setpoints of the DC/DC converter and/or the BSG unit to reduce high voltage battery power consumption to thereby avoid or delay turning on the internal combustion engine to reduce CO2 emissions.
