Abstract
Methods and systems are provided for operating a driveline of a hybrid vehicle that includes an internal combustion engine, an electric machine, an integrated starter/generator, and a transmission are described. In one example, transmission output torque and electric machine torque are adjusted while a brake pedal and accelerator pedal are contemporaneously applied.
Claims9
A driveline operating method, comprising:
- generating a total vehicle torque via a machine, the total vehicle torque based on adding a first requested amount of braking torque to a first requested amount of vehicle acceleration torque in response to an accelerator pedal and a brake pedal being contemporaneously applied in a first mode, the first requested amount of braking torque responsive to brake pedal position, the first requested amount of vehicle acceleration torque responsive to accelerator pedal position;
- and
- generating a second requested amount of vehicle acceleration torque via an engine and generating a second requested amount of braking torque via an electric machine in response to the accelerator pedal and the brake pedal being contemporaneously applied in a second mode, the second requested amount of vehicle acceleration torque responsive to accelerator pedal position, the second requested amount of braking torque responsive to brake pedal position.
