  • the counter starts at the first full hour or half an hour following the moment when the user acted on the manual interlocking member, i.e. at the moment when the motorist arrives at the parking place , and counts down a predetermined time interval, for example 3/4 of an hour, before activating the audible and luminous warning signal.
  • This device does not replace a parking disc since it does not permanently indicate the end time for authorized parking. It is intended to accompany the motorist who has left his vehicle on the parking area. It is essential that the motorist thinks of switching on his device when leaving the vehicle.
  • German patent application No. 28 51 596 which includes a device for displaying the arrival time and a device for displaying the departure time, these two values being separated by a constant time interval.
  • This device does not take into account the particularities of the parking rule in a restricted area, for example in a blue area, where a range of arrival times corresponds to a single departure time, the real time interval between arrival and the departure being variable according to the actual arrival time and the location of this arrival time within the arrival time range.
  • the present invention proposes to overcome the drawbacks mentioned above by making a simple device, which engages automatically when the vehicle stops in a parking space, and which comprises both an electronic device remaining inside the vehicle and functioning as a disc traditional parking and a warning device which accompanies the motorist to inform him of the approach of the end of the authorized parking period.
  • the apparatus according to the invention is characterized in that said electronic device is provided with a device emitting a signal linked to said authorized parking period, and in that said warning device is equipped with a organ receiving the signal emitted by the transmitter, a unit for processing the information contained in this signal and an organ transmitting an alarm signal controlled by said processing unit, arranged to emit said alarm signal before l expiration of the authorized parking period.

  • the departure time determined by circuit 12
  • the number of minutes between arrival time and departure time minus five minutes is 158 minutes.
  • the number of pulse packets is thirty-one, that is, the result of dividing 158 by 5 rounded down.
  • the warning device 11 comprises a receiving member 16 arranged to receive the signal emitted by the transmitting member 14.
  • This member is preferably constituted by a transducer designed to convert the ultrasonic pulses picked up into electrical pulses emitted at the output 17 of the 'receiving member 16.
  • These pulses are transmitted to a filter 18 whose tuning frequency is equal to the frequency of the pulses generated by the circuit 12, so as to eliminate the parasitic pulses.
  • the pulses filtered by the filter 18 are transmitted to the input of an amplifier 19 whose role is to bring their level to a value sufficient to allow their subsequent processing by a logic circuit.

  • a divider element 29 comprises for example a quartz oscillator followed by several divider circuits making it possible to have well-defined frequency signals, used respectively by the various components to which it is connected.
  • One of the frequencies available at the output of the dividing element 29 corresponds for example to a pulse every five minutes, which is directly linked to the input 32 of the counter 25 to cause the counting of the value loaded by means of the train of pulses, which will have the effect, in the absence of new loads, of bringing the state of the counter to zero after a time counted in minutes, equal to the number loaded multiplied by five.
  • This zero state corresponds to the appearance of a signal emitted at the output 33 of the counter 25, this signal being intended for the alarm generated by the member 28 emitting a warning signal.
  • the signal emitted at the output 33 of the counter causes a change of state of the flip-flop 27, the output of which is connected to the logic circuit 31 serving to select an audible frequency, a slow pulse and a limit duration of the alarm at through these connections with the divider element 29.

  • the transmitter 14 and the receiver 16 are designed such that the range of the information transmitted from one to the other is relatively small. Indeed, the countdown operation should start as soon as the link between the transmitter 14 and the receiver 16 is interrupted, that is to say when the motorist leaves his parked vehicle.
  • the electronic device for determining and displaying the end of an authorized parking period essentially consists of a microprocessor 40 or an equivalent circuit associated with a clock 41 serving as a time base and supplying in particular the clock signals necessary for the operation of the microprocessor 40, and of a display device 42 arranged to simultaneously display the arrival time or possibly a time interval within which the arrival time and the departure corresponding to the end of the authorized parking time.
  • switches 43 can be brought into contact with corresponding inputs of the microprocessor 40, to allow modification of the internal registers corresponding respectively to tens of hours, hours, tens of minutes and minutes. By these switches, it is possible to reset the time of the device, provided however that the contactor 44 is in a "time setting" position, in which it closes the circuit corresponding to the input 45 of the microprocessor 40.
  • the operating mode of the device can be modified for use based on parking rules different from those of the blue zone, especially those corresponding to the so-called red zone.
  • This mode of use is advantageously displayed by means of an indicator light 47 or any other suitable member fitted to the display device 42.
  • the member 47 is controlled by means of an electrical connection with the microprocessor 40, indicated by line 48.
  • a pilot decoder is mounted, the function of which is to transform a decimal coded information conveyed by the four lines 51 linking the microprocessor 40 to the decoder 50 in a representation in numbers composed using seven segments, the control signals of which are transmitted by the seven lines 52.

  • This external information is used to control the display of the time of day on the corresponding display screen 49, as well as the control of the display of the departure time determined as a function of the arrival time.
  • This command is carried out at regular intervals, as long as the signal brought to the input 57 indicates that the vehicle is in circulation.

  • the day is divided into a number of time intervals, each of which is linked to a specific time which is the end time for authorized parking.
  • the microprocessor determines in which of these time intervals falls the time of day at which the parking period begins, that is to say the time of arrival of the automobile on the parking area.
  • the microprocessor establishes the correspondence between this time interval and the mandatory start time of the automobile and controls the display of this start time.
  • the input 57 of the microprocessor 40 intended to receive said external information
  • a sensor such as for example an accelerometer capable of determining at any time whether the vehicle is on or off.
  • an accelerometer capable of determining at any time whether the vehicle is on or off.
  • An accelerometer makes it possible to detect the various accelerations and to deduce therefrom whether the vehicle is in traffic, stationary or if it has been subjected to an impact while it was stationary. Such equipment is advantageously used to provide the external information transmitted to the input 57.
  • this equipment consists of a piezoelectric element 60 to which a mass 61 is mechanically linked.
  • This mass is connected to the piezoelectric element 60 in such a way that any accelerated positive or negative ration generates a force capable of elastic deformation of the piezoelectric element.
  • This element is arranged in such a way that its sensitivity to lateral accelerations undergone by the vehicle is extremely low, while the sensitivity to accelerations parallel to the axis of the vehicle is maximum.

  • the corresponding monostable forms a pulse of a certain duration T 1 defined as a function of the time constant of the piezoelectric element 60.
  • This pulse has the effect of inhibiting the monostable element corresponding to the acceleration of contrary signs which is induced by the elasticity of the piezoelectric element. Thanks to the symmetrical mounting of the two monostable elements 68 and 69, each appearance of a first signal corresponding to an acceleration blocks, for a duration T 1 , the signal corresponding to a deceleration.
  • the outputs of the monostable elements 68 and 69 are connected to the inputs of two other monostable elements 70 and 71.
  • the function of these two additional monostable elements 70 and 71 consists in defining the duration of a time interval T 2 greater than T l , during which the device collects information relating to the movements of the vehicle. If, during the time interval T 2 , the device detects at least two accelerations of opposite signs, it will provide, at input 57 of the microprocessor (see fig. 2), external information signifying that the vehicle is in normal circulation . This information is transmitted by means of two AND logic gates 72 and 73.
  • the output of one of the monostable elements 70 or 71 When the output of one of the monostable elements 70 or 71 is activated indirectly by an acceleration of a certain sign, it transmits a validity signal on one of the inputs of the corresponding logic gates 72 or 73. If a signal corresponding to an acceleration of opposite sign appears during the time interval T2 on the other input of the AND logic gate, a signal may be emitted at the output of this gate.
  • the two outputs of logic gates 72 and 73 are connected to the inputs of an OR logic gate 74.
  • the output of logic gate 74 therefore provides a signal whenever at least two accelerations of opposite signs have appeared during the interval time T 2 , thus signaling to the electronic device described above that the vehicle is traveling normally. The absence of acceleration and corresponding signal means that the vehicle is parked.
  • the transmission of the external information signal to the device illustrated in FIG. 2 can be carried out by a direct electrical connection, for example the contactor actuated by the ignition key.
  • the accelerometer of FIG. 3 is integrated into the circuit of FIG. 2.
  • the diagram of the above device could be modified and that certain components or groups of components could be replaced by one or more equivalent components, in particular in the case of the application of integration techniques.
