Problems solved by technology

[0002] The available output power of the motor / generator in a hybrid vehicle may be limited when the hybrid vehicle is operated in an electric-only (EV) mode of operation
This power limitation may be caused by the need to preserve a certain amount of energy required to start the internal combustion engine when the vehicle transitions from EV mode of operation to hybrid or engine-only mode

Abstract

A vehicle includes and an engine, a motor, a transmission, and a controller. The transmission is configured is to receive power from the engine and the motor. The transmission is also configured to shift between gears based on a shift schedule. The controller is programmed to, in response to only the motor providing power to the transmission, adjust the shift schedule to narrow an operating speed range of the motor such that the motor speed maintains a peak range of an available motor power output.

Description

technical field [0001] The present disclosure relates to hybrid vehicles and transmission shift strategies for hybrid vehicles. Background technique [0002] When a hybrid vehicle is operating in an electric-only (EV) mode of operation, the available output power of a motor / generator in a hybrid vehicle may be limited. This power limitation may be due to the need to preserve a certain amount of energy required to start the internal combustion engine when the vehicle transitions from EV operating mode to hybrid or engine-only mode. Contents of the invention [0003] A vehicle includes an engine, a motor, a transmission and a controller. The transmission is configured to receive power from the engine and the motor. The transmission is also configured to shift between gears based on a shift schedule. The controller is configured to adjust the shift schedule to narrow the operating speed range of the motor in response to only the motor powering the transmission such that th...
