Stellantis is redesigning how launch management works for future hybrids
Future Stellantis efficiency hybrids might have launch management, a newly found patent submitting signifies.
A patent utility for a hybrid-specific launch management system from the automaker was printed by the United States Patent and Trademark Workplace (USPTO) Aug. 8, 2024, after being filed by Stellantis in February. The applying discusses not solely making use of launch management—which assists the driving force in getting off the road rapidly—to hybrids.

Present launch management methods, which typically require the driving force to carry the brake and accelerator pedals after which launch the brake pedal to set off, do not work properly with hybrid powertrains, Stellantis claims within the utility. They typically give the transmission management unit precedence to direct the applying torque, which may unnecessarily stress electrical motors and produce jerky launches, in line with the automaker.
Stellantis’ proposed different would change precedence to the hybrid system’s controller, guaranteeing that each the internal-combustion and electrical motor are on the identical web page. A “preparation section” would guarantee electric-motor torque is dialed down earlier than increase engine revs. A second “launch section” would then feed in electric-motor torque alongside the combustion engine.

The kind of internal-combustion engine Stellantis has in thoughts is not talked about within the patent utility, however the automaker does focus on a dual-clutch transmission, one electrical motor used for propulsion, and a second belt-driven starter/generator motor. So it is attainable we’ll see this structure on future Stellantis hybrids.
Amongst Stellantis’ many manufacturers, hybrids with launch management look like the most effective match for Dodge. The muscle-car model is so dedicated to residing life 1 / 4 mile at a time that it as soon as employed Vin Diesel—Dominic Toretto himself—as a spokesperson. The 2024 Dodge Charger arrives later this yr in all-electric Daytona type, with a twin-turbo inline-6 powertrain following in 2025. Maybe we’ll see a hybrid as properly.
