A hybrid vehicle powertrain is configured to provide a regenerative-braking torque limit on a transmission during a regenerative-braking downshift. The regenerative-braking downshift event has sequential boost, start, torque, inertia, and end phases. The transmission may be operated in absence of a regenerative-braking torque limit during the boost and start phases to recapture more energy. The transmission may be operated with a regenerative-braking torque limit during the torque and inertia phases to protect for an input shaft speed dip that may occur without the limit. The limit may be removed once the regenerative-braking downshift event is completed.

In einem Fahrzeug teilt eine Steuerung eine Route in Routensegmente auf. Die Steuerung betreibt eine Traktionsbatterie über den Routensegmenten, um bei Abschluss eines der Routensegmente einen Ziel-Ladezustand zu erreichen. Der Ziel-Ladezustand basiert auf einer Ziel-Batterieleistung, die durch eine Klassifizierung für jedes der Routensegmente, einschließlich des einen der Routensegmente, entsprechend einem Satz von Fuzzy-Regeln definiert wird, die auf mit den Routensegmenten verknüpfte Fahrzeugbeschleunigung und Fahrbahnsteigung angewandt werden. Fuzzy-Regeln können auf die Klassifizierung für jedes der Routensegmente angewandt werden. In a vehicle, a controller divides a route into route segments. The controller operates a traction battery over the route segments to achieve a target state of charge upon completion of one of the route segments. The target state of charge is based on a target battery power defined by a classification for each of the route segments, including the one of the route segments, according to a set of fuzzy rules applied to vehicle acceleration and road gradient associated with the route segments. Fuzzy rules can be applied to the classification for each of the route segments.
