Patent number: 6424900Abstract: A control-by-wire control system comprising a plurality of control device(s), each control device is responsive to, and configured to receive a control signal. Also included in the control-by-wire control system is a plurality of sensors wherein certain sensors are coupled to particular control devices. The sensors, each sense a parameter of the system and generate various sensor signals in response. A plurality of control modules is also included in control-by-wire control system. Each control module is interfaced to at least one of the control devices and is adapted to receive at least one or more sensor signals. The control modules also generate control signals for communication to the control devices. A communication interface of at least two communication networks provides communications among various control modules.Type: GrantFiled: February 1, 2001Date of Patent: July 23, 2002Assignee: Delphi Technologies, Inc.Inventors: Brian Thomas Murray, Joseph G.

Patent number: 6411061Abstract: A combined drive circuit for a split brake system of a motor vehicle has a switched reluctance motor and a brush motor. The switched reluctance motor has multiple phase windings. The combined drive circuit includes a DC power source with first and second supply buses. A SR motor driver supplies current to the switched reluctance motor. The SR motor driver has a first capacitor coupled to the phase windings for storing energy from the phase windings and a second capacitor coupled to the first capacitor and a third supply bus, thereby developing a third supply bus voltage across the second capacitor. A brush motor driver is coupled to the first and second capacitor. The SR motor driver is adapted to supply current to the brush motor. The brush motor driver includes first, second, third and fourth switching elements coupled to the brush motor.Type: GrantFiled: December 12, 2000Date of Patent: June 25, 2002Assignee: Delphi Technologies, Inc.Inventors: Robert John Disser, Patrick Allen Mescher

Patent number: 5900712Abstract: A low cost switched reluctance motor drive circuit is achieved by establishing an alternate supply bus which effectively extends the voltage range of the DC supply for the drive. The alternate bus is maintained at a voltage which is either higher or lower than the supply voltage. A first capacitor is connected in parallel with the supply voltage and a second capacitor is connected between the alternate bus and one terminal of the supply voltage. At least one of the motor phase windings is connected in parallel with the first capacitor and at least one other of the phase windings is connected in parallel with the second capacitor. The phase winding(s) drawing energy from the first capacitor return inductive current to the second capacitor, and the phase winding(s) drawing energy from the second capacitor return inductive current to the first capacitor.Type: GrantFiled: February 20, 1998Date of Patent: May 4, 1999Assignee: General Motors CorporationInventors: Robert John Disser, Patrick Allen Mescher
