A hybrid vehicle has an engine, an electric machine connected to the engine by an upstream clutch, a transmission gearbox connected to the electric machine by a downstream clutch, and a controller. The controller is configured to, in response to a user commanded shift of the transmission, control the electric machine speed to a designated speed based on gearbox output speed and the transmission gear ratio after the shift, thereby synchronizing speeds across the gearbox for the shift. A method for controlling a hybrid vehicle provides, in response to a user commanded shift of an automatic transmission gearbox, controlling an electric machine speed to a target speed based on the transmission gear ratio after the shift where the target speed is synchronized with the transmission gearbox output speed.
A vehicle comprising:
A method for controlling a hybrid vehicle having an engine selectively coupled to an electric machine by an upstream clutch with the electric machine selectively coupled to an automatic transmission gearbox by a downstream clutch, comprising, in response to a user commanded shift of the gearbox, controlling the electric machine speed to a target speed based on the gearbox gear ratio after the shift where the target speed is synchronized with the gearbox output speed;
A method for controlling a vehicle having an electric machine (M/G) connected to an engine and an automatic transmission gearbox by upstream and downstream clutches, respectively, comprising, in response to a user commanded gearbox shift, controlling the M/G to a target speed synchronized with the gearbox output speed based on the gearbox gear ratio after the shift;
