Claim 0:
1. A control method for a host vehicle, the method comprising the steps of:
a) acquiring a speed Vx of the host vehicle, a relative speed Vr between a preceding vehicle and the host vehicle, and a relative distance Dr between the preceding vehicle and the host vehicle;
b) calculating a perceived risk level PRL as a function of said speed Vx of the host vehicle, said relative speed Vr, said relative distance Dr, and at least one of variables Vx*Vr and Vx2;
c) controlling at least one vehicle device of the host vehicle as a function of the perceived risk level;
wherein in step b), the perceived risk level PRL is calculated based on equation (1):

PRL=(Dr−Pb*V)/(Pa*V); wherein  (1)

Pa, Pb are five components vectors; and
V=(1; Vx; Vr; Vx*Vr; Vx2).
