Abstract
Systems and methods for improving operation of a hybrid vehicle are presented. In one example, driveline disconnect clutch operation is adjusted in response to vehicle mass so that the vehicle may operate similarly at lower and higher vehicle masses.
Claims19
A method for operating a hybrid vehicle, comprising:
- adjusting operation of a driveline disconnect clutch in response to a change in vehicle mass;
- adjusting engine stopping timing of an engine coupled to the driveline disconnect clutch in response to the change in vehicle mass;
- and
- adjusting an engine torque output by adjusting turbocharger boost of the engine coupled to the driveline disconnect clutch.
1 more element
A method for operating a hybrid vehicle, comprising:
- adjusting operation of a driveline disconnect clutch in response to a change in vehicle mass and a driver demanded torque;
- and
- automatically stopping an engine at a time that is responsive to the change in vehicle mass.
A method for operating a hybrid vehicle, comprising:
- adjusting operation of a driveline disconnect clutch that is in communication with an engine in response to a change in vehicle mass;
- automatically stopping the engine in response to a first energy storage device state of charge being greater than a first threshold state of charge, the first threshold state of charge based on a first vehicle mass before the change in vehicle mass;
- automatically stopping the engine in response to a second energy storage device state of charge being greater than a second threshold state of charge, the second threshold state of charge based on a second vehicle mass after the change in vehicle mass;
- and
- in response to an engine start that is transmission shift related, starting the engine during transmission shifting.
