Patent number: 9776635Abstract: An auto stop-start equipped vehicle power management system includes a primary power source supplying energy to an electrical starter to crank a vehicle engine and a secondary power source coupled in parallel to the primary power source. The secondary power source supplies energy to electric loads during an engine auto stop-start operation. The electrical loads maintain vehicle subsystem functionality during the engine auto stop-start operation. The energy supplied to the electrical loads is current limited during the engine auto stop-start operation. A controllable switch decouples the secondary power source from the primary power source and starter motor during the engine auto stop-start operation.

Patent number: 9284896Abstract: A method for maximizing the availability of start-stop operations within a microhybrid vehicle includes determining the electric current drawn by a set of electrical components of the vehicle, from the vehicle's battery. The internal resistance of the vehicle's battery, and the resistance of a starter motor loop circuit coupled to the engine of the vehicle are dynamically calculated. The closed-circuit voltage of the battery is predicted, using the internal resistance of the battery, the resistance of the starter motor loop circuit, and the current drawn by the set of electrical components of the vehicle. The start-stop operation is carried out if the closed-circuit voltage of the battery is predicted to be above a pre-determined minimum value.Type: GrantFiled: January 31, 2013Date of Patent: March 15, 2016Assignee: FORD GLOBAL TECHNOLOGIES, LLCInventors: Ravi Atluru, Chuck De Biasi, Xiangying Liu, Zeljko Deljevic, David Celinski, David Anthony Symonow, Eric Michael Rademacher, Kirk Pebley, Dave W.

Patent number: 6194877Abstract: A fault detection method is disclosed for a motor vehicle charging system including a generator and an electrical component coupled to receive electrical current from the generator. In one embodiment, the method comprises sensing a first voltage at an output of the generator and sensing a second voltage at the electrical component and, if the first voltage and the second voltage differ by more than a predetermined amount, reducing or suspending output of electrical current from the generator. One advantage of the method disclosed herein is in its ability to diagnose a fault in an electrical connection at the output of a motor vehicle generator, where the fault manifests itself as a high resistance connection.Type: GrantFiled: August 2, 1999Date of Patent: February 27, 2001Assignee: Visteon Global Technologies, Inc.Inventors: Alan Francis Judge, John Francis Renehan, Zeljko Deljevic

Patent number: 5745534Abstract: A voltage regulation system for an automobile comprises a voltage regulator and a powertrain control module. The powertrain control module has a quartz crystal as its time base, while the voltage regulator has a less-expensive, though more environmentally robust resistive-capacitive (RC) oscillator. The voltage regulator and powertrain control module communicate between one another using pulse-width modulation. Drift in the frequency of the RC oscillator in the voltage regulator is recognized through the powertrain control module's measurement of the frequency of the signal sent by the voltage regulator. The powertrain control module adjusts the frequency of the signal it sends to the voltage regulator, assuring that the drift in frequency of the RC oscillator does not inhibit accurate PWM communications between the two devices.Type: GrantFiled: June 4, 1996Date of Patent: April 28, 1998Assignee: Ford Motor CompanyInventors: Charles James DeBiasi, Vikas Tuteja, Zeljko Deljevic, John Francis Renehan

Patent number: 5481176Abstract: An enhanced charging system for a motor vehicle includes an alternator, a voltage regulator, and an engine controller. The voltage regulator and engine controller are connected by two circuits. One of the circuits provides the engine controller with a measure of the torque about to be applied to the engine by the alternator. The other circuit allows the engine controller to command the target voltage at which the voltage regulator is to control the alternator. The engine controller determines the target voltage based on intake air temperature, a measure of the temperature of the air at the intake of the engine. The engine controller then modifies the target voltage based on (1) whether the throttle of the engine is near wide-open-throttle; (2) whether the brakes of the vehicle are applied; and (3) whether the alternator is about to apply an increased torque to the engine.Type: GrantFiled: July 5, 1994Date of Patent: January 2, 1996Assignee: Ford Motor CompanyInventors: Charles J. DeBiasi, Vikas Tuteja, Zeljko Deljevic, John F. Renehan
