Definitions

  • the invention relates to a method and a device for checking the driving suitability of the driver of a track-bound vehicle of the type described in CH-A 612 340 described in the preamble of claim 1 and 4, respectively.
  • the method and the device according to the invention are advantageous primarily in vehicles that take part in road traffic, in particular in motor vehicles, the method and the device can be used with any other means of transport, work machines or with all the "man-machine" that is in continuous operation. Systems used successfully to control vigilance.
  • Some devices are said to reduce monotony by creating wake-up stimuli.
  • Such a device is e.g. B. described in US-A 3,611,344. It creates a periodically repeating stimulus for the driver. The driver is assigned the task of clearing the signal with the hand switch. If the extinguishing does not take place, the device switches off the ignition of the engine or the alarm flashing lights are switched on.
  • a serious disadvantage of this device is that rhythmic stimuli, by which the monotony is increased, are emitted, which stimuli can distract attention in city traffic in situations at risk of accidents.
  • a device used in railways has been manufactured for similar purposes; this is described in DE-C 1 199312.
  • This device gives the call signals depending on the speed, i.e. in a much less predictable rhythm and, in conjunction with the so-called "dead man's switch", is also capable of sensing the decrease in muscle tone.
  • the device since the device has been developed for rail-bound vehicles, it cannot be used for road traffic due to its design and functional principle.
  • DE-C 2 404 963 shows the tendency of further development of such devices.
  • one tries to compare the measured oscillation values with one another on the basis of the sample taken for each route. Such a comparison could only be regarded as objective on long stretches with path areas of unchanged quality.
  • the device described in DE-C 2 042 853 continuously controls not only the change in the oscillation value but also the quality of the corrective movements. If at all possible, with the help of these devices, all faster or slower changing moments (such as the inclination angle of the road surface, the quality of the tires, ice, snow, cross wind, play of the steering wheel, the load on the car, etc.) ), which determine the quality of this fatigue phenomenon at the same time, there is the objection that the devices mentioned only perceive the final state of fatigue and not - it is not even possible - the strange anomalies preceding sleep consider steering wheel actuation.
  • the device described in US-A-4005398 strives to present the superfluous alarms resulting from the inadequacy of the method and presenting an accident risk to reduce the resulting chance of accidents.
  • This solution actually represents the combination of the individual characteristics of the devices described in US-A 4,031,527 and US-A 3,222,639.
  • the basic principle is that the steering maneuvers are counted as a function of the speed and the oscillation fluctuations of the steering wheel are observed . If one of the values falls below the threshold value, a warning acoustic stimulus is given.
  • the solution known from CH-A 612 340 approaches the control that is considered to be ergonomically optimal.
  • the most important characteristic of the solution is that the impulses coming from sensors of the vehicle operating elements are used with a “real time” character, which eliminates the possibility of dividing attention.
  • This device already controls a more objective fatigue symptom, namely the extension of the reaction time, i. H. if no impulse arrives from the controls, the result being registered by means of a suitable auxiliary device.
  • the disadvantage of the device is that the connection of the sensors is a very labor-intensive assembly work or, if only the minimally required three points, namely the brake, the clutch, the steering wheel or the turn signal, are connected, the observation during a long period of time in front of itself should go, during which the decrease in attention can no longer be ruled out.
  • the problem with passenger cars which have elastic performance in the various speed levels.
  • a separate operating element is required to give the answer and the extension of the reaction time is evaluated with the real biological value scale compared between quite wide limits.
  • the device accepts the impulse of the sensor circuit monitoring the stability of the energy network (e.g. braking, acceleration) during the measurement period of the vigilance control, as a reaction and shifts control to a later date.
  • the stability of the energy network e.g. braking, acceleration
  • the driver's readiness is checked in such a way that after a time that cannot be determined in advance, one of the flashing indicator lamps (the right or left) on the instrument panel for e.g. is switched on for a maximum of 3 seconds. If such lamps are missing, one of the “command lamps” arranged on the front plate of the apparatus can be switched on. Simultaneously with the activation, a short «preparatory» horn signal can be given.
  • the direction to the right or to the left of the "command lamp” is unknown in advance, and the mode of operation differs from the usual one, so it lights up with a continuous light in such cases.
  • the driver's task is to move the arm of the direction indicator switch in a direction corresponding to the signal and immediately return to the middle position when the “command” is perceived.
  • the duration of the electrical signals perceived between the activation of the direction indicator and the withdrawal of the same is determined, which represents a value which characterizes the coordination of the series of movements and the own reflex activity and which is particularly prolonged when the driver is in a drunk state; the direction of the reaction movement is perceived and agreement with the direction of the command is established.
  • the premature or excessive character of the movement is ascertained, namely whether the arm has come to a standstill during the return movement or whether it has given an impulse to the line on the opposite side, moving over the middle.
  • the response voltage is delayed for a predetermined time, which is shorter than 0.5 seconds, so that the automatic blinker is now unable to switch.
  • the so-called heat-wire machines most frequently used today work with a delay corresponding to the period mentioned above. Under normal conditions, the movement of the return can be carried out with complete certainty in 0.5 sec.
  • the device evaluates the measurement results in complexes, i.e. H. weighed the individual data according to the value of the driving function and gave it to the driver e.g. known by a combination of light diodes of different colors, such as green, yellow, red, or by a digital display, for example from 1 to 99 (4th requirement).
  • a weighted evaluation can be achieved, for example, in such a way that the duration of the simple perception time or that of the withdrawal required movement direction rotation in a ratio of 1: 4 - compared to the normal biological values - is taken into account; a movement response made in the wrong direction is reported as a “measurement to be repeated”, the poorly coordinated, overflowing movement as a “weak ” result.
  • the device reacts to such a lack of measurements with a new measurement attempt, which continues until a complete control suitable for data evaluation takes place.
  • the duration of the next “perception of the activity level” is electronically programmed (5th request), in a ratio inverse to the measured vigilance, e.g. in the range between 8 and 120 seconds, continuously varied.
  • the measuring mode i.e. maintain the "repeated measurement” with a continuous horn signal for a further two seconds; if the answer is still missing, an immediate alarm is triggered.
  • the external emergency lights of the vehicle are switched on immediately, the horn emits a discontinuous signal, but if necessary, the ignition of the engine can be switched off and the brake can be activated.
  • the alarm signal only stops when the vehicle is parked. Incidentally, the result obtained in the course of the repeated measurement is reported back with a proper evaluation of the error points.
  • the measurement results are registered in the device, e.g. B. in the manner described in CH-PS 612 340, by controlling the encoder of the recorder on a pie chart.
  • the device ensures the official usability of the measurement results after an accident or during a routine check in road traffic by a circuit that controls the display of the respective last check after the operating supply voltage used during the trip has been switched off by turning the ignition key or The handbrake is kept in operation by means of an independent supply voltage.
  • the power requirement ie the current consumption of this circuit, can be neglected;
  • the circuit automatically displays a digital or colored display of the measurement result last saved.
  • the device according to the invention is capable of preventing the use of the vehicle before starting for an unauthorized person under the influence of alcohol or medication.
  • the device according to the invention considers the signals coming from the direction indicator switch of the vehicle as a response to the warning signal in the course of the measurements taken on the move, it is capable of changing the order and duration of the direction indicator to the right or to the left and through perceive and measure the provoked tensions also in retirement.
  • This series of movements consists of switching on the direction indicator arm at least four times, but only in the coded order, i.e. «Playing the code».
  • the four changes in the left or right direction comprise 16 signal combinations to which only one represents the "key" of a given vehicle.
  • the device From the first direction signal emitted in the correct direction, the device begins to measure the time that has elapsed up to the fourth, that is, the last signal. Should this period of time exceed a biologically acceptable minimum level, for example about 3.5 seconds, the fact of “unsuitability” is likely. In this case, the cycle with the “identification phase” is started until the suitable measured value arrives.
  • a biologically acceptable minimum level for example about 3.5 seconds
  • the device according to the invention immediately concludes that it is “unauthorized”; in the same way, it is considered unauthorized if the code is not played while the identification mode is waiting or if a further consumer impulse arrives from the sensor from start-up (e.g. through the use of the starter).
  • the device When the unauthorized person is determined, the device automatically switches on the alarm mode already described - emergency flashing light, external horn, but also the ignition circuit can be finally interrupted.
  • the alarm signal can only be switched off by repeatedly pressing the hidden push button. Repeated use of the same only starts the monitoring phase.
  • the push button does not finally switch off the function mentioned, it is ensured that a driver who is under the influence of alcohol cannot drive the vehicle even if he knows the location of the button. If someone does not press the hidden push button when parking the car, they must take the risk of stealing the car.
  • the device does not need a separate operating element in the vehicle, since the control is carried out using the direction indicator arm.
  • one of the terminals of the battery AKKU forming the energy source is provided with a ground connection, while a line section 18 is connected to the other terminal.
  • the electricity flows through these to the various consumers.
  • the supply voltage supply of the vehicle and the corresponding terminals of the control device according to the invention are connected via the ignition switch 1 and the hand brake switch 2.
  • the device itself consists of three parts, namely the signaling part, the control part and the display and operating part.
  • the solution shown here as an example contains a sensor circuit 4, which senses the magnitude and speed of the current change, to which an activity counter 3 is connected, while to the direction indicator switch 8 of the vehicle, with the interposition of a delay circuit 9, a reaction time measuring circuit 10 is connected, which is connected to the activity counter 3 in Two-way connection is established.
  • An alarm unit 13 is connected to the reaction time measuring circuit 10, the output of which is connected to an automatic blinker 14 of the vehicle to which the external emergency flashing lights 15 of the vehicle are connected.
  • the command signal lamps 5 and 6, the horn 7, a display device 11 and a registration device 12 are connected in the same way to the reaction time measuring circuit 10.
  • a monitoring counter 17 is also shown, which can be operated with a push button 16.
  • the counter 17 is used to monitor the driver for fitness to drive when starting the journey and to protect against unauthorized entry.
  • the device used to control and perceive the decrease in the activity and alertness of the driver is put into operation, ie the activity counter 3 begins to work.
  • the sensor circuit 4 senses the magnitude and speed of the current flowing through the line section 18 and accordingly sends pulses to the activity counter 3.
  • the activity counter 3 is reset to pulses coming from the sensor circuit 4 caused by the driver's activity. However, if the pulse fails to appear, one of the command signal lamps 5 and 6 will light up after the preset time has elapsed. At the same time the horn 7 emits an acoustic signal.
  • the driver has to turn the direction indicator switch 8 in a direction corresponding to the illuminated command signal lamps 5 or 6 and immediately return it to the central position without the outer direction indicator light up.
  • the role of the command signal lamps 5 and 6 can be taken over by the direction indicator lamps if a separate control light is provided for each of the two directions.
  • the acknowledgment signal coming from the direction display switch 8 is evaluated with the interposition of the delay circuit 9 with the aid of the reaction time measuring circuit 10. On the basis of the evaluation, the corresponding signals reach the display device 11 and the registration device 12.
  • the activity duration 3 that is to be considered next is programmed into the activity counter 3. Every pulse arriving during the measurement through the sensor circuit 4 causes a delay. If the driver gives no or an incorrect answer, ie the arm of the direction indicator switch 8 is turned in the wrong direction, the alarm device 13 is activated, which actuates the external emergency flashing lights 15 via the flashing lights 14.

  • the line section 18 is expediently formed by the cable present between the rechargeable battery and the ignition switch 1, but at the same time the change in consumption due to the voltage fluctuation of the point without a ground connection on the rechargeable battery, generally the positive terminal, can be characterized with great certainty.
