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.

In one aspect of the invention, a system for preventing stall of a vehicle engine is provided. The system includes an integrated starter alternator operably connected with the engine. The integrated starter alternator is capable of selectively operating as a starter motor for transmitting torque to the engine and as an alternator for producing electric energy. The system also includes at least one electric energy storage device in electrical communication with the integrated starter alternator. The system further includes at least one controller in electrical communication with the integrated starter alternator. The system includes at least one sensor operably connected with the engine sending a signal indicative of engine performance to the controller. The controller compares the signal to a predetermined condition indicative of engine stall and controls the electric energy storage device and the integrated starter alternator to transmit a torque to the engine sufficient to prevent engine stall.

Use of integrated starter alternator to prevent engine stall

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.

A vehicle, having an engine ( ) and a transmission ( ), also includes an integrated assembly ( ) between the engine ( ) and transmission ( ) which includes both a torque converter assembly ( ) and an integrated starter-generator (ISG) assembly ( ). The ISG assembly ( ) is mounted between the torque converter assembly ( ) and the transmission ( ), with an ISG rotor ( ) rotationally coupled to an impeller ( ) through an assembly having compliance to allow for proper assembly and operation of the integrated assembly ( ).

Integrated torque converter and starter-generator

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.

ISA engine start-stop strategy

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.
