Methods and systems for extending regenerative braking

摘要

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.

1. A method for controlling driveline braking, comprising:
providing driveline braking via an electric machine while rotation of an engine is stopped, the electric machine providing negative torque equivalent to an amount of torque the engine provides during deceleration fuel shut off while providing driveline braking; and automatically activating a device to consume charge provided via the electric machine while the electric machine is providing driveline braking and the engine is stopped and remains stopped.
