Patent number: 10724491Abstract: An electric starter system is used with an engine. The starter system may include a solenoid device coupled to a pinion gear, a brushless starter motor connectable to the engine via the pinion gear during a requested engine start event, and a controller. In response to the start event, when the engine speed is less than a threshold speed, the controller delivers a control current to the solenoid device at a peak current level sufficient for translating the pinion gear into contact with the flywheel. The control current is reduced to a holding current level less than the peak current level after the pinion gear is engaged with the flywheel. Motor torque is commanded from the starter motor, through the pinion gear, and to the flywheel while maintaining the holding current level, and held for a duration sufficient for starting the engine.Type: GrantFiled: May 1, 2018Date of Patent: July 28, 2020Assignee: GM Global Technology Operations LLCInventors: Chandra S. Namuduri, Kenneth J. Shoemaker, Chunhao J. Lee, Lei Hao, Thomas W. Nehl, Suresh Gopalakrishnan

Patent number: 8901934Abstract: A circuit that detects if contacts in an HV contactor have been welded or stuck closed. The circuit includes a controller that generates a short duration pulse signal that closes a driver switch and allows current flow through a coil in the HV contactor. The current flow is converted to a voltage by a sensor, where the voltage is received by the controller. The controller uses the voltage, such as by comparing the voltage to a stored representative voltage of the coil current for when the HV contactor is open, to determine whether the HV contactor is closed, and possibly welded or stuck closed, or partially closed. The sensor can be the driver switch or another device, such as a resistor.Type: GrantFiled: August 4, 2011Date of Patent: December 2, 2014Assignee: GM Global Technology Operations LLCInventors: Andrew J.
