First Claim
Patent Images
1. A method for vehicle braking, comprising:
- providing driveline braking torque to a vehicle without applying friction braking torque to the vehicle; and
reducing driveline braking torque while increasing friction braking torque to the vehicle in response to an energy storage device state of charge, the friction braking torque increased by a same amount the driveline braking torque is reduced.

14. A vehicle system, comprising:
-
an engine; a dual mass flywheel including a first side mechanically coupled to the engine; a driveline disconnect clutch mechanically including a first side coupled to a second side of the dual mass flywheel; a driveline integrated starter/generator (DISG) including a first side coupled to a second side of the driveline disconnect clutch; a transmission selectively coupled to the engine via the driveline disconnect clutch; friction brakes; and a controller including non-transitory instructions executable to automatically stop engine rotation, provide a driveline braking torque via the DISG, and apply the friction brakes while reducing the driveline braking torque. - View Dependent Claims (15, 16, 17, 18, 19, 20)
