Patent number: 10173613Abstract: Systems and methods for monitoring the state of charge of a battery of a vehicle are provided. A battery monitor having a processor and a memory is configured to monitor an operating voltage and a loaded voltage of the battery. An electric power steering system is configured to be supplied with power from the battery. The battery monitor is configured to calculate a voltage drop between the operating voltage and the loaded voltage when the battery is under load from the electric power steering system. The battery monitor compares the voltage drop to a predetermined voltage drop and determines that the state of charge of the battery is low when the voltage drop is greater than or equal to the predetermined voltage drop. The battery monitor instructs the electric power steering system to operate in a limited state when the state of charge of the battery is low.Type: GrantFiled: August 18, 2015Date of Patent: January 8, 2019Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Scott R.

Patent number: 8886412Abstract: A steering system for an autonomously driven vehicle and methods of steering the vehicle are disclosed. A main controller signals a secondary steering assembly to operate in a first phase when a power steering controller is in a first mode and a second phase to steer the vehicle when the power steering controller is in a second mode. The main controller signals a friction device to actuate to a disengaged position when the power steering controller is in the first mode and the secondary steering assembly is in the first phase, and to signal the friction device to actuate to an engaged position to secure a steering wheel in an initial position when the power steering controller is in the second mode and the secondary steering assembly is in the second phase to allow the secondary steering assembly to steer the vehicle.Type: GrantFiled: March 14, 2013Date of Patent: November 11, 2014Assignee: GM Global Technology Operations LLCInventors: Kenneth L.
