Abstract: A powertrain system is controlled to deliver axle torque in response to an operator accelerator pedal input. Axle torque is determined by metrics including historical control information, current control information, and future control information.

Abstract: A control system for an engine includes a speed error determination module that periodically determines an engine speed error rate based on a difference between a measured speed and a desired speed of the engine, and a torque reserve module that monitors the engine speed error rate and that selectively adjusts a torque reserve of the engine based on the engine speed error rate. The torque reserve module maintains the torque reserve at a predetermined first torque reserve amount while the engine speed error rate is less than a predetermined first error rate and selectively increases the torque reserve above the first torque reserve amount when the engine speed error rate increases above a predetermined second error rate greater than the first error rate. The torque reserve module decreases the torque reserve when the engine speed error rate decreases below the first error rate. A related method is also provided.

Abstract: A strap tensioning apparatus (26) suitable for use in a motor vehicle having strap (11) for retaining a sensor (12) strapped inside a tire/wheel assembly (14) is described. The strap tensioning apparatus includes an arcuate member (28) having a first radius of curvature along a longitudinal axis unequal to the installed radius of curvature. The difference in radii of curvature is such that the arcuate member will maintain a predetermined tension in the strap (11) in the event the strap relaxes during normal use, thus preventing the dislocation of the strap (11) and sensor (16) relative to an installed location.
