Abstract: A control method for a host vehicle (100), the method comprising the steps of: a) acquiring a speed Vx of the host vehicle, a relative speed Vr between a preceding vehicle (200) and the host vehicle (100), 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 based on equation (1a): PRL=PRL(Vr,Vx,Dr)??(1a) with the PRL function decreasing when Vx/dr increases, with Vr being constant; c) controlling at least one vehicle device (32, 34, 36, 38) of the host vehicle as a function of the perceived risk level (PRL). A computer program, a non-transitory computer-readable medium, and an automated driving system for implementing the above method.

Abstract: A synchronization system for a spread spectrum communication receiver generates a receiving code sequence which is identical to an input code sequence and then varies the timing of the receiving code sequence using a correlator until the two code sequences are correlated.
