Abstract: Methods and systems are provided for monitoring a steering system of a vehicle. In one embodiment, a method includes: receiving torque signal data corresponding to torque signals received from a torque sensor associated with the steering system; processing the torque signal data to determine an average torque value; determining a health status of an alignment of the steering system based on the average torque value; and generating at least one of a signal, a message, and a code to notify a user based on the health status.

Abstract: An idler arm assembly employed in a steering assembly of a vehicle having a body. The idler arm assembly comprises: an idler housing mounted to the body and including a bore; a pivot shaft mounted in the bore and being rotatable and telescopically slidable in the bore, with the pivot shaft having a cavity at a first end; an idler arm having a first end supported by the second end of the pivot shaft and a second end that supports the steering assembly; a ball stud having a ball end secured in the cavity and supporting the pivot shaft in the telescopically slidable direction, and a shank having threads; and a threaded cap secured to the idler housing and engaged with the threads on the shank, whereby rotation of the threads relative to the threaded cap will telescopically slide the pivot shaft relative to the idler housing.

Abstract: An engine control system for controlling the engine to transition between an activated mode where all cylinders are active and a deactivated mode where less than all cylinders are active is provided. The system includes: a noise vibration and harshness (NVH) limit module that determines a noise, vibration, and harshness (NVH) torque limit based on the engine speed and the vehicle speed; and a mode transition module that enables the engine to transition between the deactivated mode and the activated mode while limiting noise, vibration, and harshness based on the NVH torque limit and a requested torque.

Abstract: A method for controlling the speed in a vehicle includes adjusting at least one gain parameter based on a vehicle speed error and the displacement on demand mode of the engine. A new cruise throttle area is calculated from the adjusted gain parameter.
