Patent number: 7037234Abstract: 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.Type: GrantFiled: December 10, 2003Date of Patent: May 2, 2006Assignee: Visteon Global Technologies, Inc.Inventors: Gurinder Singh Kahlon, James J. Klocinski, Ning Liu, Shawn Harold Swales

Patent number: 6756763Abstract: 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.Type: GrantFiled: May 2, 2002Date of Patent: June 29, 2004Assignee: Visteon Global Technologies, Inc.Inventors: Gurinder Singh Kahlon, Ning Liu, Robert Joseph Mohan, Richard Eric Luken

Patent number: 6380701Abstract: An electrical charge assembly 10 for use within a vehicle 12 having a transmission 20, a starter assembly 16, and an engine 14. The assembly 10 includes a capacitor assembly 34 which selectively provides electrical charge to the starter assembly 16, effective to allow the engine 14 to be activated. The starter 16 may be selectively coupled to the transmission 20, effective to increase the torque produced by the transmission 20 and may selectively provide electrical charge to the capacitor assembly 34.Type: GrantFiled: March 31, 2000Date of Patent: April 30, 2002Assignee: Visteon Global Tech., Inc.Inventors: Gurinder Singh Kahlon, Ning Liu, Robert J.

Patent number: 6233935Abstract: A system (40) for starting an internal combustion engine (12) of an automotive vehicle (10) has a controller (54) coupled to a starter/alternator (42). The engine (12) has a crankshaft (50) and a turbocharger (24). The controller (54) initiates the starting of the engine (12) by rotating the crankshaft (50). The rotating crankshaft (50) displaces an amount of air from the cylinders (14) of the engine (12) to rotate the rotor shaft of the turbocharger (21). The turbocharger (25) thus draws in air, compresses the air and provides the compressed air to the cylinders (14). When the engine is started the initial power is increased due to the compressed air.Type: GrantFiled: December 7, 1999Date of Patent: May 22, 2001Assignee: Ford Global Technologies, Inc.Inventors: Gurinder Singh Kahlon, Ning Liu, Robert Joseph Mohan
