4) if the up-down and left-right adjustment is not needed, whether the head of the passenger leans against the headrest is further judged: if the distance sensing system detects that the distance is more than 6 centimeters, the headrest becomes the thickest critical state, the distance is more than 15 centimeters, and the driving fatigue is prompted when the duration exceeds 10 seconds; if the pressure sensor measures the pressure value, the head of the driver is judged to lean against the headrest, and at the moment, the pressure sensing automatic adjusting system is triggered to adjust the headrest according to the value calculated by the formula F which is ah + bx;
