Abstract
Description
Titel: Waarschuwingsstelsel voor slipgevaar bij voertuigen.Title: Vehicle slip hazard warning system.
De uitvinding heeft betrekking op een stelsel dat bestuurders van voertuigen waarschuwt dat slipgevaar dreigt.The invention relates to a system that warns drivers of vehicles that there is a risk of slipping.
Voertuigen en meer in het bij zonder personenauto's 5 worden de laatste jaren van steeds meer systemen voorzien om de bestuurders te waarschuwen voor gevaarlijke situaties, het optreden van aanrijdingen te voorkomen en, in het onverhoopte geval van een aanrijding, te beschermen. Het betreft hierbij onder meer buitentemperatuurmeters, 10 signaalgevers bij een lage buitentemperatuur, ABS systemen, veiligheidsgordels, airbags etc.Vehicles and more in particular passenger cars 5 have been increasingly equipped in recent years to warn drivers of dangerous situations, prevent collisions and, in the unlikely event of a collision, protect them. This includes outside temperature meters, 10 signalers at a low outside temperature, ABS systems, seat belts, airbags, etc.
Uit GB-A-2 253 294 is een systeem bekend dat aan de bestuurder van een voertuig een waarschuwing geeft indien de afstand tot een voorligger te klein is. Dit systeem 15 houdt rekening met de benodigde remweg, maar is volledig handbediend. De bestuurder voert zijn momentane snelheid in en activeert het systeem voor de eerste maal op een moment dat de voorligger een referentiepunt passeert en voor de tweede maal als hijzelf het referentiepunt passeert. Het 20 systeem berekent op basis hiervan of de afstand te klein is en geeft, indien dit het geval is, een waarschuwingssignaal af.GB-A-2 253 294 discloses a system that gives a warning to the driver of a vehicle if the distance to the vehicle in front is too short. This system 15 takes into account the required braking distance, but is completely manually operated. The driver enters his instantaneous speed and activates the system for the first time when the vehicle in front passes a reference point and for the second time when he passes the reference point. Based on this, the system calculates whether the distance is too short and, if so, issues a warning signal.
Uit EP-A-494.763 is een systeem bekend dat de bestuurder informeert over de luchtdruk in de banden van 25 het voertuig en de temperatuur van de lucht in de banden. Dit systeem kan tijdig waarschuwen voor lekken of oververhitte banden.From EP-A-494.763 a system is known which informs the driver about the air pressure in the tires of the vehicle and the temperature of the air in the tires. This system can provide early warning of punctures or overheated tires.
Uit EP-A-351.274 is een gelijksoortig systeem bekend dat op basis van de luchtdruk en de temperatuur van de 30 lucht in de banden een maximale snelheid adviseert.EP-A-351.274 discloses a similar system which recommends a maximum speed on the basis of the air pressure and the temperature of the air in the tires.
Geen van de bekende systemen is in staat om op een betrouwbare wijze te waarschuwen voor slipgevaar. Buitentemperatuurmeters die een signaal afgeven als de temperatuur beneden bijvoorbeeld 3°C daalt, houden een veel 1 f; 2 te grote veiligheidsmarge aan en houden geen rekening met de diverse andere factoren die bepalen of een specifiek voertuig wel of geen gevaar loopt te slippen.None of the known systems is able to reliably warn against slipping hazard. Outside temperature meters that give a signal if the temperature drops below, for example, 3 ° C, keep a lot of 1 f; 2 too large a safety margin and do not take into account the various other factors that determine whether or not a specific vehicle is at risk of skidding.
De uitvinding beoogt te voorzien in een systeem dat 5 volledig automatisch een zeer betrouwbare indicatie omtrent een veilige snelheid aan de bestuurder van een voertuig geeft wanneer het risico bestaat dat het voertuig gaat slippen.The object of the invention is to provide a system which gives a fully reliable indication of a safe speed to the driver of a vehicle fully automatically when there is a risk that the vehicle will slip.
De uitvinding voorziet hiertoe in een stelsel om 10 bestuurders van voertuigen te waarschuwen dat slipgevaar aanwezig is voorzien van - middelen voor het meten van de temperatuur buiten het voertuig; - middelen voor het meten van de snelheid van het voertuig; 15 en - een computer die diverse meetgegevens en vaste gegevens kan opslaan en op basis daarvan berekeningen kan uitvoeren,- gekenmerkt door 20 - middelen om de luchtvochtigheid buiten het voertuig te bepalen en de gemeten waarde toe te voeren aan de computer; - middelen om de rolweerstand van de banden ten opzichte van het wegdek te bepalen en de gemeten waarde in de 25 computer in te voeren; en doordat de computer op basis van de ingevoerde gegevens een adviessnelheid berekent en deze aan de bestuurder meldt.To this end, the invention provides a system for warning drivers of vehicles that a risk of slipping is present, comprising - means for measuring the temperature outside the vehicle; - means for measuring the speed of the vehicle; 15 and - a computer capable of storing various measurement and fixed data and performing calculations on the basis thereof, - characterized by 20 - means for determining the humidity outside the vehicle and supplying the measured value to the computer; - means for determining the rolling resistance of the tires in relation to the road surface and entering the measured value in the computer; and because the computer calculates an advisory speed on the basis of the data entered and reports this to the driver.
De combinatie van een meting van de buiten-30 temperatuur en de luchtvochtigheid maakt het voor de computer mogelijk te bepalen of er sprake is van een aanpassing van het wegdek door regen, ijzel, sneeuw of bevriezing. De berekende adviessnelheid is de snelheid waarbij onder de gegeven omstandigheden geen slipgevaar 35 optreedt.The combination of a measurement of the outside temperature and the air humidity makes it possible for the computer to determine whether there is an adjustment of the road surface by rain, sleet, snow or freezing. The calculated advisory speed is the speed at which no slipping hazard occurs under the given circumstances.
1011/80 31011/80 3
De rolweerstand van de banden ten opzichte van het wegdek kan bepaald worden met behulp van een eventueel in de auto aanwezig traction control systeem. Volgens een andere uitvoeringsvorm van de uitvinding is het echter ook 5 mogelijk de rolweerstand van de banden te berekenen op basis van de snelheid, het gewicht van het voertuig, dat eventueel momentaan gemeten kan worden om rekening te houden met de belading, en de profieldiepte van de banden. Het bandenprofiel kan automatisch worden gemeten, 10 bijvoorbeeld bij licht of geluidsgolven, die vanaf het chassis naar de band worden gericht en bijvoorbeeld bij het starten van de motor het profiel meten en de gemeten waarde toevoeren aan de computer. Het is ook mogelijk de profieldiepte handmatig in te voeren, bijvoorbeeld bij 15 iedere servicebeurt, waarbij de computer op basis van de gemeten afgelegde afstand, gegevens over het bandentype etc. kan berekenen hoe groot de slijtage op een bepaald ogenblik geweest is en op grond daarvan de resterende profieldiepte kan bepalen.The rolling resistance of the tires in relation to the road surface can be determined using a traction control system that may be installed in the car. According to another embodiment of the invention, however, it is also possible to calculate the rolling resistance of the tires on the basis of the speed, the weight of the vehicle, which can optionally be measured momentarily to take into account the load, and the tread depth of the tires. The tire profile can be measured automatically, for example with light or sound waves, which are directed from the chassis to the tire and, for example, measure the profile when the engine is started and supply the measured value to the computer. It is also possible to enter the tread depth manually, for example at every service, where the computer can calculate the wear at a given moment on the basis of the measured distance traveled, information about the tire type, etc. can determine the remaining profile depth.
20 In plaats van het aangeven van een adviessnelheid, waarbij volgens de computerberekening geen slipgevaar aanwezig is, kan het systeem ook worden ingericht om actief in te grijpen in de snelheid van het voertuig en deze omlaag te brengen. Het systeem dient daartoe gekoppeld te 25 worden met het remsysteem en/of het motormanagementsysteem van de auto.Instead of indicating an advisory speed, where according to the computer calculation there is no risk of slipping, the system can also be arranged to actively intervene in the speed of the vehicle and to lower it. To this end, the system must be coupled to the braking system and / or the engine management system of the car.
De uitvinding zal worden toegelicht aan de hand van de figuur die een blokschema van een mogelijke opbouw van het stelsel volgens de uitvinding toont.The invention will be elucidated with reference to the figure, which shows a block diagram of a possible construction of the system according to the invention.
30 Op een computer 1, meer in het bijzonder een microprocessor, zijn aangesloten een buitentemperatuurmeter 2, een luchtvochtigheidsmeter 3, een snelheidsmeter 4 en middelen 5 voor het bepalen van de grip van de banden van het voertuig op de weg. De middelen 5 35 kunnen gekoppeld zijn aan een traction control systeem van de auto, indien dit aanwezig is, maar kunnen ook gegevens 10*1/80 4 over het gewicht van de auto en de profieldiepte van de banden omvatten. Op basis van de aan de computer 1 toegevoerde gegevens en de in het ROM geheugen van de computer opgeslagen tabellen berekenen deze of er 5 slipgevaar bestaat. Indien dit het geval is geeft de computer aan een display 6 een signaal af om een adviessnelheid weer te geven. Indien gewenst kan bij een te hoge momentele snelheid ook een visueel of akoestisch alarmsignaal worden gegeven. T^r verdere informatie van de 10 bestuurder kan tenslotte de grip van de auto op de weg in procenten ten opzichte van de ideale situatie worden getoond.Connected to a computer 1, more particularly a microprocessor, are an outside temperature gauge 2, an air humidity meter 3, a speedometer 4 and means 5 for determining the grip of the tires of the vehicle on the road. The means 535 may be coupled to a traction control system of the car, if present, but may also include data 10 * 1/80 4 on the weight of the car and the tread depth of the tires. On the basis of the data supplied to the computer 1 and the tables stored in the ROM memory of the computer, these calculate whether there is a risk of slipping. If this is the case, the computer gives a display 6 a signal to indicate an advisory speed. If desired, a visual or acoustic alarm signal can also be given if the current speed is too high. Finally, further information from the 10 driver can show the car's grip on the road in percentages compared to the ideal situation.
Een verdere verfijning van het systeem wordt verkregen indien de computer onderscheid maakt tussen een 15 veilige snelheid bij rechtuit rijden en bij het rijden in een bocht. De laatstgenoemde snelheid kan afzonderlijk worden weergegeven, zodat de bestuurder daarop kan anticiperen bij het ingaan van de bocht.A further refinement of the system is obtained if the computer distinguishes between a safe speed when driving straight ahead and when driving around a bend. The latter speed can be displayed separately so that the driver can anticipate this when entering the corner.
