Stabilization diagram identified by CoS-SSI. (a1) SD of CoS-SSI (J = 1/1st subset). (a2) Selecting mode by the rate of the stable frequency over orders for on road vehicle modal identification (J = 1). (b1) SD of CoS-SSI (J = 2/2nd subset). (b2) Selecting mode by the rate of the stable frequency over orders for on road vehicle modal identification (J = 2). (c1) SD of CoS-SSI (J = 3/3rd subset). (c2) Selecting mode by the rate of the stable frequency over orders for on road vehicle modal identification (J = 3).
