Abstract: A steering system for an automotive vehicle is disclosed. The steering system includes a steering column assembly, a steering wheel assembly secured to the steering column assembly, the steering wheel assembly comprising a steering wheel frame, a steering wheel rim, and a hub, and an emulator enclosed within a housing, the emulator secured to the steering column assembly. The steering wheel frame and the hub are stationary and the steering wheel rim rotates relative to the steering wheel frame and the hub.

Abstract: A steering assembly for a vehicle includes a steering gear including a steering gear housing enclosing a steering rack, the steering rack coupled to a tie rod at a joint, at least one boot assembly configured to enclose the joint between the steering rack and the tie rod. The at least one boot assembly includes a first boot proximate to the joint and a second boot disposed outward of the first boot. The first and second boots define a void therebetween.

Abstract: Methods and systems are provided for monitoring steering gear overtravel in rack and pinion steering systems. The provided systems and methods introduce a change in the length of the fastener that attaches an inner tie rod ball joint housing within a steering gear rack bar. The provided systems and methods also monitor the disengagement of that fastener (also referred to as overtravel and as rack travel) to generate flags and provide them to the Controller Area Network (CAN) bus of the vehicle.

Abstract: 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.

Abstract: 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.
