摘要:
A method is disclosed for controlling the operation of a mild hybrid electric vehicle 5 having an engine 10 and high and low voltage power systems selectively connectable via a DC to DC converter 14. The method comprises whenever possible using only a low voltage battery 16 forming part of the low voltage power system to power low voltage loads 17 during an engine E-stop performed automatically to save fuel and reduce emissions and whenever possible using only a high voltage battery 13 forming part of the high voltage power system to recharge the low voltage battery 16 when the engine 10 is restarted following the E-stop.
摘要:
An apparatus for starting an engine 11 of a mild hybrid vehicle 5 is disclosed having low and high voltage starting devices 13 and 14 controlled by an electronic controller 10. The electronic controller 10 is operable to use the high voltage starting device 14 as a motor to crank the engine 11 whenever possible so as to partially discharge a high voltage battery 18 and facilitate the increased use of automatic stopping and starting of the engine 11.

An method for starting and operating an engine 11 of a mild hybrid vehicle 5 following start-up is disclosed for an engine 11 having low and high voltage starting devices 13 and 14 controlled by an electronic controller 10. The method comprises using the high voltage starting device 14 as a motor to crank the engine 11 whenever possible so as to partially discharge a high voltage battery 18 and then using the high voltage starting device 14 as a generator after starting the engine 11 if the exhaust gas temperature needs to be increased so as to assist with light-off of one or more exhaust gas aftertreatment devices 6.
