An engine shut off system for a hybrid electric vehicle includes an internal combustion engine, an electric motor, and a controller. The internal combustion engine is located in the hybrid electric vehicle and is coupled to the electric motor. The vehicle system controller is coupled to the internal combustion engine and may automatically shut off or start the internal combustion engine. When the hybrid electric vehicle is completely stopped the controller shuts the internal combustion engine off after a configurable period of time.

A control system is provided for the drive system of automotive vehicles. A control determines a combination of torque to be applied from an integrated starter-generator and compression torque to be applied from an engine. The combination of the integrated starter-generator torque and engine compression torque results in a desired deceleration torque. The control preferentially applies torque from the integrated starter-generator over the compression torque, thus maximizing regeneration.

There is provided a method for automatic operation of a vehicle comprising an engine, a starter motor, an engine clutch, and a plurality of vehicle systems. After detecting that the engine is running, the vehicle systems are checked to ensure an acceptable status for shutting down the engine. A negative torque is applied to the engine to shut it down. Vehicle systems are monitored until they indicate that the engine should be restarted. The engine is restarted, and a successful start of the engine is then confirmed. Similarly, there is provided a method for the cold start of a vehicle as above. The starter motor is powered up with an initial torque and vehicle systems are monitored to determine whether the engine should be started. The engine is started from the torque of the starter motor, and a successful start of the engine is then confirmed.

A method for controlling an induction motor using an equivalent circuit model, the equivalent circuit having a real component and an imaginary component, is disclosed. The method instead of measuring a plurality of induction motor parameters, the real and the imaginary component of the induction motor impedance are calculated based on the measured phase currents and voltages. The invention calculates a first control function based on the real component of the induction motor impedance, and a second control function based on the imaginary component of the induction motor impedance, and adjusts the induction motor excitation frequency until the first control function is approximately equal to the second control function. After the excitation frequency is determined, the motor torque is calculated by taking the square of motor voltage in the d-q reference frame. Working with a few control parameters, the present invention achieves a desired maximum torque or a desired peak efficiency with a high tolerance of variation in the control parameters.

A system ( ) for starting an internal combustion engine ( ) of an automotive vehicle ( ) has a controller ( ) coupled to a starter/alternator ( ). The engine ( ) has a crankshaft ( ) and a turbocharger ( ). The controller ( ) initiates the starting of the engine ( ) by rotating the crankshaft ( ). The rotating crankshaft ( ) displaces an amount of air from the cylinders ( ) of the engine ( ) to rotate the rotor shaft of the turbocharger ( ). The turbocharger ( ) thus draws in air, compresses the air and provides the compressed air to the cylinders ( ). When the engine is started the initial power is increased due to the compressed air.
