In particular, embodiments of the presently disclosed technology incorporate reference tracking for driving input and vehicle state into this common control scheme. In some embodiments, this common control scheme may be implemented using Model Predictive Control (MPC).

An embodiment method for controlling a hybrid vehicle includes driving a motor that starts an engine of the hybrid vehicle and controlling the motor to generate an engine starting torque to prevent a vibration of the engine, wherein the engine starting torque is generated by a feedforward control method. An embodiment device for controlling a hybrid vehicle includes a motor configured to start an engine of the hybrid vehicle, and a controller configured to drive the motor and control the motor to generate an engine starting torque to prevent a vibration of the engine, wherein the engine starting torque is generated by a feedforward control method.

A system and method for operating a hybrid vehicle that shuts down an internal combustion engine during idle and slow speed operations and instead drives a power transmission with an electric traction motor. A vehicle operating at higher speeds, under increased operating demands, or other operating conditions automatically switches from electric propulsion to internal combustion engine propulsion. This operational mode is configurable and at all times seamless to the driver and vehicle operations. By designating the low speed, low demand operation of the vehicle to the more efficient electric mode, fuel consumption can be reduced, and overall vehicle efficiency can be maximized.

Systems and methods for starting an engine that may be started via an electric machine and a driveline disconnect clutch are described. In one example, the method estimates a maximum motor propulsive torque during engine starting. The maximum motor propulsive torque may be based on an estimated speed that a torque converter impeller speed will be when an engine cranking period ends.
