Wrong calculation of rolling resistance
07-29-2011, 03:51 PM,
#13
 
Pacejka ’94 logitudinal:
C = b0
D = (b1 * Fz + b2) * Fz
BCD = (b3 * Fz + b4) * Fz * exp(-b5 * Fz)
B = BCD / (C * D)
Sh = b9 * Fz + b10
Sv = b11 * Fz + b12
X = k + Sh
E = ((b6 * Fz + b7) * Fz + b8) * (1 - b13 * sign(X))
Fx = D * sin(C * atan(B * X - E * (B * X - atan(B * X)))) + Sv

Set b11, b12, b13 to 0 and you will get the formula used in vdrift. Can you compare to '96?
