1. An apparatus comprising:

  • a controller operably coupled to at least one accelerometer sensor that transmits a first acceleration signal, the controller configured to;

    determine a lateral acceleration based on the first acceleration signal;

    determine a force index based on an amount of force exerted on a wheel;

    compare the force index to a threshold force index and the lateral acceleration to a threshold lateral acceleration; and

    deploy a restraint based on the comparison of the force index to the threshold force index and the lateral acceleration to the threshold lateral acceleration.
