1. A motor vehicle comprising:

  • a blind-spot detection system comprising a remote sensor located adjacent a rear corner of the vehicle and having a beam pattern covering a blind spot sensing zone disposed in a rear quadrant of the vehicle, the remote sensor further having a side impact sensing zone disposed in a forward quadrant of the vehicle;

    a side impact sensor mounted at a side impact portion of the vehicle;

    an occupant safety device operable to protect an occupant during an impact on the side impact portion of the vehicle; and

    a control module receiving signals from the side impact sensor and the blind-spot detection sensor and operative to;

    calculate an approach vector of an object detected in the side impact sensing zone and/or the blind spot sensing zone;

    determine, based on the approach vector, that the object is likely to impact the side impact portion of the vehicle;

    initialize a side impact algorithm controlling activation of the occupant safety device;

    detect, based on the signals received from the impact sensor, an impact on the side impact portion of the vehicle and determining a magnitude of the impact;

    compare the magnitude of the impact with a threshold value established at least in part based upon the magnitude of the approach vector; and

    activate the occupant safety device if the magnitude of the impact exceeds the threshold value.
