Methods and systems are provided for controlling a vehicle engine to deliver desired torque to a power take off device coupled to the engine. In one example, the method may include, learning a filtered PTO torque demand during vehicle acceleration, and steady state operation, and during transition in engine states using the learned PTO torque demand to adjust engine speed in order to deliver a desired engine torque output for optimal operation of the PTO device.

Methods and systems for power take off device torque delivery

A vehicle system includes a power electronics device and a coolant circuit thermally coupled to the power electronics device. The coolant circuit includes a fluidic pump and a fluid/air heat exchanger, an air pump configured to transfer air across the fluid/air heat exchanger, and a shutter device configured to control airflow across the fluid/air heat exchanger. A controller controls the fluidic pump to control coolant flow through the fluid/air heat exchanger to reject heat from the power electronics device to the coolant and correspondingly controls the air pump and the shutter device to control airflow across the fluid/air heat exchanger to reject heat from the coolant to achieve a preferred heat rejection from the power electronics device.

Method and apparatus for controlling a coolant circuit thermally coupled to a power electronics device

A system and method for controlling an engine in a vehicle to facilitate heat transfer to a passenger compartment is provided. A number of conditions are examined, and if it is found that one or more of these conditions matches a corresponding predetermined condition, the spark timing of the engine is retarded. In addition, a charge motion control valve is opened, thereby increasing the amount, and reducing the turbulence, of the air entering the engine. This facilitates hotter combustion within the engine, and therefore faster heat transfer to the vehicle passenger compartment.

System and method for controlling an engine in a vehicle

A method for selectively adjusting an amount of fuel to an engine in a vehicle is provided. The vehicle includes an electric machine operatively connected to the engine and capable of controlling a speed of the engine. The method includes providing an amount of fuel to the engine based at least in part on a desired output of the engine, which is based at least in part on a driver input. The electric machine is commanded to control the engine speed based at least in part on the driver input. An output error of the engine is determined based at least in part on the command to the electric machine. The amount of fuel provided to the engine is adjusted when at least one predetermined condition is met, including the output error of the engine being greater than a predetermined amount.

Vehicle and method for operating an engine in a vehicle

A method for controlling fuel injection during engine startup in a hybrid electric vehicle. The hybrid electric vehicle includes an engine, a power source, an electrical machine, and a control module. The method includes the steps of driving the engine with the electrical machine, determining whether the engine is at a target state, selecting a cylinder for fuel injection, calculating an amount of fuel to provide to the cylinder, injecting the amount of fuel, and repeating the selecting, calculating, and injecting steps for another cylinder for a predetermined number of iterations.
