Abstract

PURPOSE: To facilitate the detecting of an asleeping driving operation in a vehicle having a power steering mechanism by a method wherein the asleeping driving operation is judged with a steering operation signal produced by detecting a variation in hydrualic pressure in the powder steering mechanism.
CONSTITUTION: When no force is applied to a steering wheel 7, hydraulic oil is returned back to an oil reservoir 1 via a pump 2, a hydraulic sensor 6, a valve 21a, a valve 21b and annular grooves 23a and 23b, and thus the sensor 6 does not detect the hydraulic pressure. In turn, when the steering wheel is turned leftwardly, for example, the hydralic oil is flowed to the pump 2, the valve 21a, an oil passage 13, a pressure chamber 3a to depress a worm gear 3c leftwardly. At this time, the sensor 6 detects a hydraulic signal variation. In response to the hydraulic signal from the sensor 6, a signal 24a is produced at comparators 25 and 26 by a steering sensor 24. When the time ranging from a starting time in which the signal 24a is exceeded over the setting value V1 to a setting value V2 is shorter than the predetermined value of time, the asleeping driving is detected by a circuit of judgment 31 to generate an alarm.
