The invention represents a high reliable safety system intended for preventing catastrophes (accidents) of technic-technological system man-machine that would be caused due to drowsiness of a man.The highest degree of reliability (100%) with reference to the system security preservation has been founded upon the development of a new method for early detection and monitoring of a drowsiness process course of a man (Com. A. PIA DYNAMICS), by means of which the drowsiness process is detected at the moment of its commencement and continuously monitored up to the moment of the sleeping process occurrence.Early detection of drowsiness of a man creates real prerequisites for timely performance of procedures for the system security preservation such as: the procedure for adaptable system control with the purpose of permanently accommodating the speed of the vehicle to the driver awareness degree fall found out and the procedure for preventing the driver drowsiness (crisis biological factor) at the early drowsiness phase when the chances for success are maximum. The invention is controlled by the processing computer (14), so that both procedures for the crisis factors prevention are carried out in real time with finding out certain drowsiness process phases (out of six in total) simultaneously or in the "step-by-step" procedure.Failure of the driver drowsiness process prevention procedure in the third step of repetition (maximum dose of excitement) automatically is a sign that a hard form of drowsiness, that is, high degree of the system endangerment is in question, in which case the problem of further system security preservation is resolved by the invention by means of the adaptable system control procedure. Based on the results obtained from the vehicle speed decreased over the previous steps of action to the value of v = 20 km/h, the vehicle is timely stopped through the last step of action (v = 0 km/h) at the road length 1 = l m, practically while the driver is still in the state of consciousness (SB = 45%, 10-2 sec < tp.r.< 10-1 sec, t V.B. = 0).
