摘要： A drowsiness alarm system and method for use in automotive vehicles is set to a stand-by state in response to a specific sequence of steering wheel maneuvers which may reflect driver drowsiness, for example, a relatively long period during which the steering wheel is not turned followed by an abrupt steering adjustment. From the standby state, an alarm or display alerting the driver will be generated in response to another sequence of steering maneuver confirming driver drowsiness. The second sequence of maneuvers may be selected from among a number of conventional steering behavior criteria. If driver drowsiness is not confirmed within a predetermined period of time after initiation of the stand-by state, the system is reset to its initial state.

摘要： A device for detecting steering angle and steering direction of a steering wheel in an automotive vehicle, includes a pair of fixed contacts and a movable contact. The movable contact is arranged in connection with the fixed contacts in such a way that, when the steering wheel rotates in one direction, the movable contact engages only the first fixed contact, and when the steering wheel rotates in the opposite direction, the movable contact engages only the second fixed contact. Upon the basis of signals produced whenever the movable contact contacts one of the fixed contacts, the steering angle and steering direction are detected.

摘要： A drowsiness alarm system for a vehicle detects and signals that the vehicle driver is drowsy on the basis of the duration during which no steering adjustments are made and the magnitude and speed of abrupt steering adjustments immediately following the non-steering period. Parameters compared to the magnitude and speed of the abrupt steering adjustments in order to recognize steering behavior reflecting drowsiness are adjusted in accordance with the duration of the non-steering period.

摘要： A drowsiness alarm system for a vehicle detects the driver's increasing state of drowsiness on a basis of abnormal steering change repetitions for a fixed period of time in a monotonous driving state defined, for example, as the gear shift lever being placed at an overdrive or top position. The alarm system produces an alarm to the driver to prevent the driver from increasing the state of drowsiness. The drowsiness alarm system according to the present invention comprises: (a) a steering signal generator which generates a signal corresponding to the change of an angle through which the steering wheel is rotated; (b) a monotonous driving-state detector which detects and signals that the vehicle is traveling in a monotonous driving state; (c) a discriminator which compares the change of steering signal level from said steering signal generator for a fixed period of time with a reference value; and (d) an alarm pulse generator which outputs an alarm pulse into an alarm circuit producing an alarm in response to the input alarm pulse when the output signal from the discriminator indicating the change of steering signal for the fixed period of time exceed the reference voltage.

摘要： A fatigue alarm system and method for an automotive vehicle driver is adapted to measure periods of time during which the vehicle is driven and to subtract therefrom periods of time during which the driver rests. The driver rest periods are distinguished from brief stops of the vehicle in order to accurately measure the adjusted period of driving time. In order to distinguish rest periods from brief traffic stops, the duration of vehicle stops are measured and compared with a given value. When the vehicle stop periods are shorter than the given value, the vehicle is judged to be stopped briefly, i.e. that the driver is not resting, and the measured driving period is incremented by the measured vehicle stop period. On the other hand, when the stop periods are longer than the given value, the driver is judged to be resting. In this case, the measured stop time is subtracted from the measured driving time after being adjusted by a suitable proportionality factor. The result of measurement is visually displayed by means of a plurality of fatigue level indicator segments. The threshold levels at which each indicator segment is activated or deactivated in adjusted in accordance with its current activation state in order to avoid hunting thereof.

摘要： A safety assurance system is disclosed for use in road vehicles. The system comprises a generator for providing a warning signal in response to a predetermined condition such as dozing of the driver. A rest signal is generated when the road vehicle is at rest, and a reset switch enables the driver to manually provide a reset signal. A first alarm signal is provided which is generated in response to the warning signal until the rest signal is generated. Also provided is a second signal which is generated in response to the warning signal until the rest signal or reset signal is generated. Thus, warning signals are generated that are terminated automatically when the vehicle comes to a stop or are terminated by manual operation of a reset signal.
