Definitions
- the present invention relates to a method for adjusting the of Winter service vehicles to be discharged amount of litter itself the ride changing soil temperatures as well as a device for Implementation of the procedure.
- the spreading material is used by winter maintenance vehicles by means of a rotating Spreading plate spread, creating a spill carpet on the road is produced.
- a driver of the winter maintenance vehicle can in conventional systems via a control unit, the spread of the Adjust the spreading carpet and its spreading density. These settings be dependent on the external conditions, such as the existing wetness on the road surface and the outside temperature, through selected the vehicle driver.
- the resulting discharged Spreading quantity per distance traveled is taken into account the speed of the winter service vehicle from the controller automatically regulated.
- the amount of litter to be discharged per unit of time thus consists of the factors vehicle speed, spread and spreading density together.
- the soil temperature by means of a temperature sensor detected and automatically taken into account by the controller by the discharged amount of litter depending on the measured soil temperature is controlled.
- the problem arises that it at temperature jumps, for example when crossing a bridge, too takes a long time for the temperature sensor to measure the exact temperature and to the control unit.
- the reaction time of the temperature sensor is a limiting factor here. Until the controller then the spreading density adapted to the temperature jump, the critical point is already run over.
- Object of the present invention is therefore to be discharged Scattering amount faster to adapt to changing soil temperatures.
- a temperature sensor for measuring the ground temperature while driving, attached to a vehicle and with a Control unit connected, which is the discharged amount of litter depending on one resulting from the temperature measurement Temperature gradient changed. It is not waiting, until the actual temperature value is displayed by the temperature sensor is, but the amount of scattering is based on the temperature gradient regulated, i. depending on the speed with which the measured value specified by the temperature sensor changes.
- One steep temperature gradient thus means a sudden and strong Change of soil temperature. Based on the temperature gradient can already estimate how big the temperature change is. This can shorten the reaction time of the system and the Change the amount of litter to be transferred faster than if you wait until the temperature sensor indicates the exact temperature.
- the invention is of particular importance for safety reasons the timely adjustment of the amount of litter to be discharged to a negative temperature jump.
- a preferred embodiment of The invention provides that the amount of litter to be discharged is not just is increased when a negative temperature gradient is measured is, but that the discharged material to be discharged all the stronger is increased, the more negative the temperature gradient is. This is at very negative temperature gradients, which are at very low final temperatures suggest, even accepted, that the amount of litter more than what is actually needed. It is even appropriate to consider a safety margin.
- These Overreaction serves safety. Because such overreactions of the system normally limited to a short time, they get in the total amount of scattering material hardly noticeable and are still acceptable as an environmental impact.
- the amount of scattering material only with a negative temperature jump, not against a positive temperature jump on the basis of the temperature gradient changed.
- the winter maintenance vehicle is in addition to a Location system for determining the current vehicle position fitted.
- a suitable retrieval or receiving device can retrieve known and / or stored locations and / or are received at which a temperature jump in the ground temperature is to be expected.
- the control unit which with the Location system and the retrieval or receiving device is connected, the discharged amount of litter on reaching of the location depending on the expected temperature jump changed.
- FIG. 1 shows a winter utility vehicle 1 with one in the vehicle cabin attached control unit 2.
- the user Select a scattering level, which is the amount of scattering material to be discharged Are defined.
- the scattering level is selected by the user depending on the weather conditions and weather forecasts.
- a temperature sensor 3 e.g. an infrared camera, attached, which the Floor temperature measured without contact.
- This temperature sensor 3 is connected to the control unit 2, so that it through the scattering stage specified amount of litter to be discharged depending on the measured Temperature and, if necessary, depending on a from the temperature measurement changed resulting temperature gradient.
- the temperature gradient is on the adaptation speed of the amount of litter to be discharged negative impact reaction time of the temperature sensor 3 essential shortened. Because the system not only depends on one of the Temperature sensor 3 measured final temperature of the road surface, but from the measured values supplied by the temperature sensor 3 Also, a temperature gradient is determined and when adjusting the taken into account, even before the temperature sensor 3 indicates the actual prevailing temperature.
- the system reacts at a negative temperature gradient for safety reasons over, causing more than the short term actually necessary amount of scattering material is discharged. No later than when the temperature gradient is equal to or near zero again, i. if the temperature sensor constantly indicates the changed temperature, regulates The discharged material to be discharged again depends solely on the actually measured temperature and is no longer dependent on Temperature gradient.
- FIG. 2 shows the timing of the adaptation of one of a winter service vehicle 1 to be discharged amount of litter in a flow chart.
- the user manually sets the scatter level one.
- the temperature sensor mounted on the vehicle measures 3 the bottom temperature and initiates the measurement results on Control unit 2 on.
- the control unit 2 determines from the temperature sensor 3 delivered temperature readings a temperature gradient, due to which the amount of litter to be discharged changed becomes. Normally, the spread and the vehicle speed remain unchanged, resulting in the changed amount of scattering material directly affects the spreading density of the spreading carpet.
- the consideration of the temperature gradient in the adaptation of the can be discharged in the event of a temperature jump done in different ways.
- the temperature gradient continuously determined according to a first embodiment and the expected final temperature constantly be re-estimated. ever the more negative the determined temperature gradient is, the larger the Temperature jump through the system suspected, and accordingly the amount of litter to be discharged is adjusted. At least as long as As the temperature gradient becomes steeper, it makes sense that the system overreacted, since the final temperature at this stage is not exact is estimable. The overreaction prevents it from becoming too little amount of scattering material is discharged. Once the temperature gradient decreases again, the temperature sensor so clearly his steady state, the final temperature is much more reliable estimated. From this point on, the amount of litter to be discharged can thus be discharged set reliably according to the estimated temperature become.
- second embodiment are in the control unit 2 a provided first and a second threshold, each one define certain slope of the temperature gradient. For example by a big negative temperature jump, so one steep temperature gradient, the first threshold exceeded, so the system is controlled such that the maximum or at least a defined increased amount of scattering material is discharged. As soon as the Gradient of the temperature gradient decreases again and the second Threshold reached, which is preferably a much lower Slope defined as the first threshold, the will be discharged Scattering amount estimated on the basis of the temperature gradient Adjusted final temperature.
- the second threshold can also be set to zero be set. Then the maximum or at least increased Spreading amount as long as discharged until the temperature sensor actually indicating prevailing temperature.
- the aforementioned first and second embodiments are also combinable by e.g. the continuous estimation of the final temperature and adjusting the amount of litter to this final temperature only when a temperature gradient threshold is exceeded becomes.
- Temperature measurement can be done in existing systems using the Spread density and the spread control, integrated as an additional module be additionally dependent on the scattering density of a scattering stage to adjust the temperature gradient by the control unit 2.
- the system will change automatically due to the change Soil temperature another than that selected by the operator Scattering level selects.
- Soil temperature another than that selected by the operator Scattering level selects.
- a dosing accuracy is achieved it allows the formation of ice on the road at the lowest possible level To prevent spreading material consumption.
- the amount of litter to be discharged is preferably changed all the more, the more negative the determined temperature gradient is.
- the adaptation of the discharged Reduced amount of litter Delaying the spreading material quantity adjustment takes place again with a positive temperature gradient for security reasons, to prevent the system from acting as appropriate too little scattering spreads out. Passes a winter service vehicle 1, for example, a larger manhole cover, which in winter has a higher surface temperature than the road surface, is short-lived a positive temperature jump is determined.
- a winter service vehicle 1 for example, a larger manhole cover, which in winter has a higher surface temperature than the road surface
- the user can use the Manually changes spreading density and / or spreading width while driving. For example, he can be discharged in case of sudden onset of snowfall Increase the amount of litter by manually changing another Steufufe selects.
- the system can be equipped with an emergency button be provided, which on actuation the output of the maximum Spread rate causes.
- the winter service vehicle 1 from FIG. 1 is equipped with a positioning system , for example a Global Positioning System (GPS), which is indicated in FIG. 1 by an antenna 5.
- GPS Global Positioning System
- the current vehicle position can be determined at any time.
- those locations are stored in a memory of the control unit 2, where a temperature jump is expected (bridges, woodland, ).
- the control unit 2 determines via the location determination system when such a location is reached, wherein before reaching the location, the amount of litter to be discharged is adapted in time to the expected temperature jump.
- further locations can be called up, for example via a central station, at which a temperature jump is also to be expected.
- the location determination system, the receiving device and the control unit 2 can be integrated or modularly provided in one device.
- this is with the location system coupled control unit adaptive.
- the learning ability can vary in different ways Be distinct. In the simplest case can be in a test drive the local temperature profile and the location data of stored in critical locations with a significant negative temperature jump become. In a special variant, the temperature is on the so determined or predefined locations each crossing re-measured and with the respective location stored temperature jump data compared.
- suitable Software can be based on the stored temperature jump data and a currently measured temperature jump on for estimate the expected temperature jump in future spreading trips. In the controller, then, e.g. also be considered if the negative Temperature jump basically occurs ("hard” value) or only occasionally ("soft" value). If a relevant location is e.g.
- the location in the system may be considered "hard” Value be noted.
- the controller can then automatically adjust the spread rate or semiautomatic to the learned setting.
- a semi-automatic adjustment is e.g. makes sense for "soft" values.
- the system shows the user in good time before reaching the place intends to increase the spread rate, and the user can do this e.g. reject.
- the learned data are preferably from a central Evaluation software manages them to other litter vehicles as well to make available to the headquarters.
- danger points in which a Increasing the spreading density seems reasonable, at which a temperature jump but not expected to be supplemented manually.
- Such Locations may include bus stops or motorway exits be.
- the spreading width towards the right edge of the road increase. This in turn can be fully automatic or semi-automatic by timely notice to the driver.
