DK 2016 00124 U4

The invention relates to an automatic parking disc of the kind referred to in the preamble of claim T. When the car is stationary, the display shows the time when the car stopped and will continue until the car drives again. The main task is to determine whether the car stops or drives. Determination that the vehicle is parked must, for ease of assembly, be carried out without cables connected from the outside. This means that the device itself must be able to determine whether the vehicle is driving or parked.

Prior art

Automatic parking discs are known and can be mentioned by way of example EP1639556 and EP2384495. Both use, inter alia, acceleration sensors to determine whether the vehicle is shifting from standstill to driving and vice versa by measuring the speed changes in the direction of travel of the vehicle. Thus, in EP1639556, a minimum acceleration during the movement of the vehicle is determined in a uniform direction, namely the direction of travel, for a predetermined time.

It is thus known from e.g. EP1639556 and EP2384495 to use accelerometers to determine when driving begins and ends. By filtering and integrating the signal, a measure of the velocity is obtained when it exceeds a predetermined value, the state is changed to running and, by corresponding deceleration, is changed from running to stationary.

Purpose of production

It is desirable to develop an automatic parking disc that can safely and automatically show the correct time of arrival for a parking. It must be easy to install and adjust, and simple to operate.

The creation

The production consists of an automatic parking disc with a digital display for mounting on the inside of the windshield of a vehicle in such a way that the display can be read from the outside, which parking disc contains a housing in which the digital display is arranged as well as a printed circuit with a microprocessor , a crystal for controlling a clock, controls, a three-axis gravity sensor and a battery holder with at least one battery, which housing housing a front with the digital display and a back from which the battery holder is accessed where the microprocessor is arranged.

Determine whether the vehicle is stationary by monitoring whether the direction of gravity relative to the housing is changed by means of the three-axis gravity sensor and where the microprocessor is arranged to determine the mean value of the signals from the three-axis gravity sensor (the directions) x, y and z) for continuous periods of time, which mean values are compared from time period to time period, and it is determined that the vehicle stops when none of the mean values change more than a set limit between two consecutive time periods.

The parking disc according to the invention contains a power supply in the form of a battery comprising at least one galvanic element, so that the P-disc itself can generate enough power for the function to be maintained. It is preferable to supply the device with power from a replaceable battery and minimize power consumption as much as possible.

By determining a change in gravity as specified in the generation, the power consumption can be minimized, and in a particular embodiment, the time period is approx. 15 seconds.

Preferably, the housing is located in a holder on the inside of the windshield of the vehicle, so that adjustment can be made by means of a display, and the holder is mounted on the inside of a front by means of double-sided tape.

In a preferred embodiment, the battery holder has a lid that fits the back of the housing.

In a preferred embodiment of the automatic parking disc according to the invention, the digital display shows both a digital readout of time and one or more fields for supplementary information. Thus, a parking disc according to the production can be compactly designed and thus take up relatively little space in the windshield.

Detailed description

FIG. 1 is a front view of an automatic parking disc according to the invention, and

In the following, the production is described in detail with reference to the drawing page, where

DK 2016 00124 U4 fig. 2 shows the rear automatic parking disc separated from the holder.

Referring to the figures, the automatic parking disc comprises a housing 1 with a front face 1 a and a rear face 1 b. On the front side 1 a the housing is provided with a digital display 2 which, when mounted on the inside of the windscreen of a vehicle, can be read from the outside of the vehicle. windshield. Internally, the housing 1 is provided with means for determining whether the vehicle is moving or traveling.

The display 2 shows a digital digit with four digits, each with seven segments and a separation between minutes and hours. There is additional information in the form of characters 3, 4, 5 for summer time parking "P" and soon battery change "BAT".

At the rear, the housing is provided with control buttons 6, 7, 8, where there is a button 6 for manually setting the parking time "P". It is used where parking is done for a period of no time, such as in the weekend. For example, Requirements for use of the P-disk begin Monday morning at. At 8:00 the parking time is set to 08:00 manually by pressing “P”.

The clock setting is made by buttons 7 and 8. The button 8 ("F") is for clock setting. The button 8 is held down for approx. 3 seconds, after which minutes flash and you can set the clock by pressing the button marked “+”. Pressing "F" again switches to timer set in the same way. Thus, days, months and years continue. Pressing "F" for 3 seconds starts again. The button 7 is marked "+". The button 7 is used to change the number flashing. For each press, the number increases by 1 and holding the “+” button is counted upwards until the largest possible number for minutes, hours, month and year is displayed and starting again.

On the back there is also a battery cover 9 which covers the battery 11 in the battery holder. The disc also has a holder 10 which can be mounted on the windscreen so that the housing can be mounted therein so that the display 2 is visible from the outside.

Function

To make the provision safer and easier to implement, it is decided at the time of production to determine whether the vehicle is stationary or parked. This is most easily determined by examining whether gravity changes direction, which it

DK 2016 00124 U4 will do unconditionally during normal driving. In the case of parking, gravity will always be in the same direction. The direction of gravity is measured with a gravity sensor that measures gravity in three directions. In practice, this is done by calculating the mean values of gravity sensor signals in the directions x, y and z for appropriately long time intervals. If none of the sensors' signals have changed from time to time, the vehicle must be stationary. Different slope of the road and bumps will cause changes in gravity and hence in the mean of gravity in at least one of the three directions, provided the changes are permanent.

In order to avoid shaking and oscillations in the car as a result of blown, passing lorries or puffs from passersby giving false notification of driving and thus changing the parking time, the time interval for the mean value is chosen far in relation to such oscillations.

To make the setting as easy as possible, the unit is attached to a frame in the windshield of the car in a way that it is easy to remove. Modern cars are usually with a very sloping windshield, where there is a very short distance between the window, where the parking disc is to be placed, and the dashboard. This makes it almost impossible to read the display to be set when the unit is mounted. Likewise, the lack of accessibility makes it difficult to change the battery. By making the unit easy to remove, the setting can be done on one instead of two displays. The fixed mounting units usually have two displays. A display that can be seen from the outside and one that can be seen from the inside.

The parking disc is designed as a digital clock that measures the time in hours and minutes by means of a crystal oscillator connected to the microprocessor. When set, the internal clock is displayed with minutes, hours, days, months and years. The clock even sets summer time and leap year. When the setting is made, either a character such as (as a sign that the car is not parked) or possibly the current time on the display until the parking disc has been stationary for at least two time intervals, then the current time is displayed where movement ceased for a short moment and again then moved to the next entire neighborhood as required by law. .

Determining whether the vessel is moving or stationary

Determination of movement takes place by means of orientation sensor which is integrated in many designs. They are used, among other things, in smartphones, tablets and cameras to find

GB 2016 00124 U4 gravity direction so that the display is facing right no matter how the equipment is facing. An example might be MMA8653FC from Freescale Semiconductor.

Since the unit can be placed at random, the vertical direction or gravity vector G cannot be set at the factory, but is found by measuring gravity separately along all three axes and then looking at the changes:

G (, 9x> 9y> 9z)

It is measured in time intervals of typically 15 seconds and the mean values are found continuously. The difference between two consecutive mean values exists for each axis continuously.

The car is assumed to stop if the signals Δ _Χ , Δ _? or Δ _{ζ are} all close to zero. Which can be determined in one of the following ways:

^ _ma x) Å _max j / \ (Å _z <i Δ _ηιαχ )> Parked | Δχ | + | Ay | + | Δ _Ζ | _<Δ ηιαχ -> Parked _Δ χ + Ay + _Δ ζ _{<A% MA} => Parked

The optimum value of A _max is different for each of the three methods and the value of the chosen method is determined by experiment, taking into account that it is more important to avoid false indication of driving when kept in park than it is to straight driving on very smooth road is indicated as parking. During maneuvers during parking or when people get out of the car, the movements will indicate driving until the vehicle stops completely for two of the aforementioned time periods. Thus, the parking time is set correctly.

Unevenness and altered inclination of the road will affect the direction of gravity while driving and maneuvering during parking, so that the mean value over time intervals will vary, likewise will change speed and rotation also while no one

DK 2016 00124 U4 change will be when the vehicle is parked. Blown and passing cars or people rocking the car will probably change the direction of gravity, but the mean over the time interval will be close to zero (below the limit value) if the range is far relative to the frequency of the disturbances. Preferred range is approx. 15 seconds.

When parking, the direction of gravity will be stable and after two time intervals the signals will indicate that the car is parked. The display is then set to the next full 15 minutes as determined by legislation.
