Abstract
Systems and methods for improving operation of a hybrid vehicle are presented. In one example, an electrical load may be automatically activated to consume electrical energy produced during driveline braking so that driveline braking may be extended. The electrical load may be a windscreen heater or other device.
Claims20
A method for controlling driveline braking, comprising:
- providing driveline braking via an electric machine while rotation of an engine is stopped;
- and
- automatically activating a device to consume charge provided via the electric machine while the electric machine is providing driveline braking.
A method for controlling driveline braking, comprising:
- providing driveline braking via an electric machine while rotation of an engine is stopped;
- and
- increasing current supplied to a device while the electric machine is providing driveline braking.
A method for controlling driveline braking, comprising:
- providing driveline braking via an electric machine while rotation of an engine is stopped;
- automatically activating a device to consume charge provided via the electric machine while the electric machine is providing driveline braking;
- rotating the engine in response to a state of charge of an energy storage device;
- and
- stopping to rotate the engine when the state of charge of the energy storage device is less than a threshold level.
