VEHICLE POWERTRAIN LASH CROSSING CONTROL STRATEGY
A vehicle includes a powertrain and a controller. The powertrain includes a powerplant. The controller is programmed to, responsive to a tip-in resulting in a powertrain torque direction reversal and upon obtaining a base value of a desired powertrain lash angle, adjust a powerplant torque schedule. The controller is then subsequently programmed to adjust the desired powertrain lash angle from the base to an adjusted value based on an observed powertrain lash angle that corresponds to a maximum powertrain acceleration during the tip-in.

ACTIVE REAR SENSE AREA ADJUSTMENT OF COLLISION AVOIDANCE SYSTEM OF A VEHICLE WHEN VEHICLE IS APPROACHING A POSITIVE ROAD GRADE CHANGE
In an aspect, false alerts in a collision avoidance system of an automotive vehicle are prevented when the vehicle is in reverse. The collision avoidance system includes at least an upper rear facing obstruction sensor and a lower rear facing obstruction sensor. When the vehicle is approaching a positive road grade change, the sensitivity of the lower rear facing obstruction sensor is reduced. In an aspect, an active rear view area of a rear facing vision system of the vehicle is adjusted when the vehicle is approaching a change in road grade.
METHOD AND APPARATUS TO ISOLATE AN ON-VEHICLE FAULT
A vehicle including a monitoring system and controller for evaluating a vehicle subsystem is described. The monitoring system includes a sensor that is disposed to monitor on-vehicle noise or vibration. The subsystem includes an actuator, and a fault associated with the subsystem is defined by a fault vibration signature. A command to activate the subsystem is monitored coincident with a signal input from the sensor. A first vibration signature is determined based upon the signal input from the sensor, and a correlation between the first vibration signature and the fault vibration signature are determined for the fault associated with the subsystem. Occurrence of a fault associated with the subsystem can be detected when the correlation between the first vibration signature and the fault vibration signature associated with the subsystem is greater than a threshold correlation.
