Abstract
An apparatus for starting an engine of a mild hybrid vehicle is disclosed having low and high voltage starting devices and controlled by an electronic controller. The electronic controller is operable to use the high voltage starting device as a motor to crank the engine whenever possible so as to partially discharge a high voltage battery and facilitate the increased use of automatic stopping and starting of the engine.

An apparatus for starting an engine of a vehicle comprising:
- a belt integrated starter-generator (BISG);
- a starter motor;
- and
- an electronic controller operable to use the starter motor to crank the engine if engine temperature is less than a predefined temperature limit and to otherwise use the BISG to crank the engine provided the BISG is operable to crank the engine at a speed greater than a defined rotational speed.
