1. A road condition aware system for a vehicle comprising:

  • a first acceleration sensor that measures vertical acceleration of a component of the vehicle;

    an adaptive acceleration limits module that determines a first acceleration limit based upon a speed of the vehicle;

    a limit comparison module that generates a rough road signal based on a comparison of the first acceleration limit from the adaptive acceleration limits module and the measured acceleration from the first acceleration sensor;

    a continuously variable transmission (CVT)that includes a belt having a tension adjustment; and

    a control module that determines the tension adjustment on the belt in the CVT when the rough road signal is received from the limit comparison module.
