Abstract
System, methods, and other embodiments described herein relate to delaying a start of an internal combustion engine (“ICE”) in a hybrid vehicle. In one embodiment, a method includes identifying a stopping location, a regenerative braking event that assists in stopping the hybrid vehicle at the stopping location, and an actual energy value based on a regenerative braking energy generated during the regenerative braking event. The method includes determining an estimated energy value, based on a predicted regenerative braking energy from a predicted braking event, that causes the hybrid vehicle to stop at the stopping location. The method includes determining an energy savings value based, at least in part, on a difference between the actual energy value and the estimated energy value. The method includes, responsive to the ICE being off, delaying the start of the ICE based, at least in part, on the energy savings.
