Abstract: A power management system for a hybrid vehicle including an engine includes a vehicle power bus distributing power from a battery to vehicle loads. A capacitor includes one of a plurality of supercapacitors and a plurality of ultracapacitors. A starter/generator controller communicates with the capacitor and the battery. A power management module is configured to supply current from the capacitor to the starter/generator controller during cranking of the engine; and supply current from the battery to the starter/generator controller during the cranking of the engine. The power supplied by the battery is greater than or equal to 2% and less than or equal to 20% of a total power supplied to the starter/generator controller during the cranking of the engine.

Abstract: A system for discharging or charging a capacitor of a hybrid vehicle according to the present disclosure includes a target state of charge (SOC) module and a capacitor charge/discharge module. The target SOC module determines a target state of charge of the capacitor based on a speed of the vehicle. The capacitor charge/discharge module determines whether a state of charge of a capacitor is greater than a target state of charge. The capacitor charge/discharge module dissipates power from the capacitor to at least one of a battery of the vehicle and an electrical load of the vehicle when the state of charge of the capacitor is greater than the target state of charge.

Abstract: An automatic transmission hydraulic control module assembly, in an exemplary embodiment, includes a main body having a first side and an opposing second side. The main body includes a plurality of fluid passage cavities in the first side, and at least one bore extending from one of the fluid passage cavities through the main body and through the second side. The main body is formed from a thermoplastic material including at least one filler.
