  • Patent number: 9803608
    Abstract: Method for voltage stabilization during an engine starting event of a vehicle includes receiving, at a switch device module, an active Start_ON signal from a starter solenoid module indicating initiation of the engine starting event. At the switch device module, an auxiliary electrical energy storage device (ESD) is electrically coupled to one or more auxiliary loads within a predetermined delay since the active Start_ON signal was received. A primary ESD and a starter motor are electrically decoupled from the one or more auxiliary loads only after the auxiliary ESD has been electrically coupled to the one or more auxiliary loads. In response to a predetermined condition occurring while the primary ESD and the starter motor are electrically decoupled from the one or more auxiliary loads, the primary ESD and the starter motor are electrically coupled to the one or more auxiliary loads.

  • Patent number: 9694769
    Abstract: Apparatus for voltage stabilization in a vehicle includes a battery distribution module having a load module managing electrical power to one or more auxiliary loads, a first switch coupling a starter motor and an ESD to the load module only when closed, a second switch coupling an auxiliary ESD to the load module only when closed, and a controller integrated with a PC board attached to the first and second switch devices. The controller is configured to control opening and closing of the first and second switches based on at least one of a plurality of signals received by the controller. The primary ESD is electrically coupled a primary fuse terminal of the battery distribution module which electrically couples the primary ESD to a second terminal of the first switch and the starter motor. The auxiliary ESD is electrically coupled to an auxiliary fuse terminal of the battery distribution module which electrically couples a first terminal of the second switch to the auxiliary ESD.

  • Patent number: 9347415
    Abstract: A starter relay connects a battery with a starter motor of an engine when in a closed state and disconnects the starter motor from the battery when in an open state. A switching device provides current to the starter relay when in a closed state and disables current flow to the starter relay when in an open state. For an engine startup event, a switch control module: transitions the switching device to the closed state for a first predetermined period; transitions the switching device to the open state for a second predetermined period after the first predetermined period; and transitions the switching device to the closed state for a third period after the second predetermined period. The starter relay remains in the open state during the first predetermined period and transitions to the closed state when the switching device is in the closed state for the third period.

  • Patent number: 8332098
    Abstract: A method of controlling a power input to a compressor clutch, via an A/C clutch voltage controller, that selectively drives an A/C compressor in a vehicle HVAC system is disclosed. The method may comprise the steps of: determining a first electric power level needed to cause the compressor clutch to move to a full engagement position from a compressor clutch non-engagement position; applying the first electric power level to the compressor clutch to cause the compressor clutch to move to the full engagement position; determining a second electric power level, which is lower than the first electric power level, needed to maintain the compressor clutch in the full engagement position; and applying the second electric power level to the compressor clutch to maintain the compressor clutch in the full engagement position.
