A method for implementing program execution integrity (PEI) for a communication-based sensor includes receiving an output communication message from the sensor, the output communication message including sensor output data internally processed within the sensor. The output communication message further includes raw data used by the sensor in internally processing the sensor output data. The raw data is independently processed, and the results thereof are compared with the internally processed sensor output data so as to verify the processing integrity of the sensor to a desired tolerance.

A method, system, and apparatus for providing enhanced steering pull compensation are provided. The method compensates for steering pull in a vehicle steering system that includes a handwheel. The method includes monitoring the vehicle to determine whether the vehicle is heading forward along a substantially linear straight-ahead path and, if so, measuring handwheel torque, as a sensed torque signal, to determine an amount of steering pull existing at the handwheel. The method also includes generating a torque assist signal in response to the sensed torque signal and calculating an offset signal for reducing the amount of steering pull to substantially zero. The method further includes producing a modified torque assist signal by adding the offset signal to the torque assist signal, and applying the modified torque assist signal to the vehicle steering system.
