Description

A speed supervision module Technical fieldThe present disclosure relates to a speed supervision module, and to a method inrelation to the module.
BackgroundCargo vehicles and buses have speed limitations often being lower than the maximum speed limitation at motorvvays. For example, at motorvvays in Swedenthe maximum speed limitation is 110 km/h, but cargo vehicles and buses havenormally a speed limitation of 90 km/h. Furthermore, if a trailer is attached to atruck the vehicle speed limitation instead is 80 km/h.
Heavy goods vehicles such as trucks and buses are often equipped withtachographs. The tachograph continuously records, among others, the vehicle'sspeed. There is usually also a defined violation speed limit, which is known to thetachograph. This violation speed limit may be related to a maximum permittedspeed for the vehicle and/or a prevailing speed limit for a relevant road section.Further, the vehicle's tachograph is often arranged to register a remark, a so-called penalty point, in relation to a speeding violation for the driver, if the violationspeed limit has been exceeded during at least a predetermined violation periodT1, which may e.g. be 60 seconds. Thus, a penalty point may be registered by thetachograph if the vehicle's current speed e.g. exceeds the violation speed limit of90.5 km/h for a predetermined violation period T1 of 60 seconds or of a differentduration. ln some countries, the police may require to access the information stored on thattachograph, and also impose fines based on this information, so that the vehicle'sdriver may thus be fined retroactively based on remarks in the tachograph, whereeach individual remark (penalty point) may constitute individual grounds for a fine.The remarks are registered on the driver's personal tachograph card, and thesefollow the driver from vehicle to vehicle. ln EP-2808209 a method and system to decelerate a vehicle is disclosed which is related to the scenario described above. ln the following some other patent documents in this technical field are presented.
WO-2005/093683 relates to a method for displaying information and warningsabout speed limits in vehicles comprises, displaying information and warningswhen predetermined distance values are exceeded. The actual speed of thevehicle is determined and information and warnings are displayed depending onthe vehicle speed. Information and warnings are displayed depending on detectedand/or predetermined vehicle properties (weight, trailer etc.) and on the detectedweather conditions.
NL91001157 relates to a speed limiting system for road vehicle where the systemis adapted to decouple the accelerator pedal from the throttle if an audiblewarning is ignored. The general national maximum speed is stored internally. Areduction in the maximum speed which stems from current conditions can betaken into account if e.g. a trailer or a caravan is attached.
EP-1717134 relates to a fifth wheel safety arrangement for e.g. a towing vehicle,A sensor is connected to the electrical management system of the towing vehiclefor providing a limitation of speed of the vehicle whenever the fifth wheel is in rearposition.
WO-2007/050019 relates to a fifth wheel assembly for coupling a trailer to a trucktractor, provided with sensors that are included in a control system forpredetermined information and control of operating conditions. ln thecoupling/disconnecting mode the sensor will for example provide for a control ofone or several parameters, for example height, travelled distance, axle loadand/or speed within a low speed interval, for example up to a maximum speed of the truck to a predetermined value, for example 30 km/h.
Thus, the maximal allowed speed v for a vehicle may vary in dependence of thevehicle configuration, e.g. if a trailer is attached, and also in dependence ofexternal parameters related to the location of the vehicle (e.g. in dependence ofwhich country the vehicle presently is located in). 3 As an example, if a trailer is attached to the vehicle, the vehicle speed limitationnormally is lowered from v1 to v2, where v1 may be 90 km/h and v2 may be 80km/h.
The object of the invention is to achieve an improved safety for vehicles, and inparticular for vehicles having speed limitation restrictions in addition to the generalspeed limitations, e.g. for vehicles with trailers, and taken speed limitation restrictions of different regions/countries into account _ SummaryThe above-mentioned object is achieved by the present invention according to the independent claim.
Preferred embodiments are set forth in the dependent claims.
According to a first aspect the invention relates to a speed supervision module fora vehicle, the module is configured to receive a current speed signal includinginformation of the current speed vcurrent of the vehicle. The module is furtherconfigured to receive a vehicle configuration signal including configuration data ofthe vehicle influencing a maximal allowed speed v of the vehicle, and to receivean external parameter signal including location and speed data regarding thepresent location of the vehicle and speed information related to the location. Themodule is configured to determine the maximal allowed speed v of the vehicle independence of the configuration data and the location and speed data, whereinthe current speed vcurrent of the vehicle is compared with the determined maximal allowed speed v and an alarm-signal is generated if vcurrent is greater than v.
According to a second aspect the invention relates to a method in a speedsupervision module for a vehicle, whereas the method comprises receiving acurrent speed signal including information of the current speed vcurrent of thevehicle. The method further comprises: - receiving a vehicle configuration signal including configuration data of the vehicle 4 influencing a maximal allowed speed v of the vehicle, - receiving an external parameter signal including location and speed dataregarding the present location of the vehicle and speed information related to thelocation, - determining the maximal allowed speed v of the vehicle in dependence of theconfiguration data and the location and speed data, - comparing the current speed vcurrent of the vehicle with the determined maximalallowed speed v, and - generating an alarm-signal if vcwent is greater than v.
By implementing the module and the method according to the present inventionthe safety is improved in that the driver is notified about the current maximalallowed speed of the vehicle. ln addition the risk of getting fines for the driver isreduced. Thereby, the burden of the driver is reduced as he/she does not have tobe aware of the various speed limits in different countries/regions, and specific speed limitation restrictions related to the configuration of the vehicle.
Brief description of the drawinqs Figure 1 is a schematic illustration of a vehicle provided with a speed supervisionmodule according to the present invention.
Figure 2 is a block diagram schematically illustrating the present invention.Figure 3 is a block diagram schematically illustrating an embodiment of thepresent invention.
Figure 4 is a flow diagram illustrating the method according the present invention.
Detailed descriptionThe invention will now be described in detail with references to the appended figures. Throughout the figures the same or similar items will have the same reference signs.
With reference to figure 1 a speed supervision module 2 is provided in a vehicle 4.
The vehicle may be a cargo vehicle, a cargo vehicle including a trailer, a semi- 5 trailer, a car, a car with a trailer or house trailer, a bus, and a bus including atrailer. The expression “trailer” should be interpreted broadly as any objectcoupled to the vehicle, and in particular any object that influences the speedlimitation of the vehicle.
The vehicle 4 communicates internally between its units, devices, sensors,detectors etc. via a communication bus, for example a CAN-bus (Controller AreaNetwork) which uses a message based protocol. Examples of othercommunication protocols that may be used are TTP (Time-Triggered Protocol),Flexray, etc. ln that way signals and data described herein may be exchangedbetween different units, devices, sensors and/or detectors in the vehicle 4. Signalsand data may instead be transferred wirelessly between the different units,devices, sensors and/or detectors. These units, devices, sensors and/or detectorsare often implemented by Electronic Control Units (ECUs) specifically dedicatedto perform a specified task. The position of the vehicle 4 may be determined witha positioning unit in the vehicle. The positioning unit is arranged to determine theposition of the vehicle, and may be configured to receive signals from a globalpositioning system such as GNSS (Global Navigation Satellite System), forexample GPS (Global Positioning System), GLONASS, Galileo or Compass, andto make the current position available to other systems of the vehicle. ln figure 2 a block diagram is shown schematically illustrating the speedsupervision module according to the present invention. The module may beembodied as an Electronic Control Unit and configured to communicate to variousother units and systems of the vehicle via the CAN-bus, or any equivalentcommunication network. ln one implementation the speed supervision module isan integral part of the tachograph. ln another implementation the speedsupervision module may be a stand alone unit , communicating with said Electronic Control Unit and/or with the Tachograph.
The speed supervision module is configured to receive a current speed signal 6 including information of the current speed vcurrent of the vehicle. 6 The module is further configured to receive a vehicle configuration signal 8including configuration data of the vehicle influencing a maximal allowed speed vof the vehicle. Preferably, the configuration data includes information regarding ifa trailer is attached to the vehicle. The configuration data may also includeinformation regarding the weight of the vehicle, etc.
The speed supervision module is also configured to receive an external parametersignal 10 including location and speed data regarding the present location of thevehicle and speed information related to the location. More in detail, the locationdata may be current position information from a positioning unit, and may alsoinclude information of the maximal allowed speed in the region/country the vehicle presently is travelling in.
The speed supervision module 2 is configured to determine the maximal allowedspeed v of the vehicle in dependence of the configuration data and the locationand speed data. Thus, the maximal allowed speed v for a vehicle may vary independence of the vehicle configuration, e.g. if a trailer is attached, if the width ofthe trailer exceeds a specified maximum width, and/or if an extra heavy load iscarried, and also in dependence of external parameters related to the location ofthe vehicle (e.g. in dependence of which country the vehicle presently is locatedin).
As an example, if a trailer is attached to the vehicle, and by applying theregulation presently in force in Sweden, the maximal allowed speed for a cargovehicle having a trailer attached, is lowered from 90 km/h and to 80 km/h.
The speed supervision module 2 is configured to compare the current speedvcurrent of the vehicle with the determined maximal allowed speed v and togenerate an alarm-signal 12 if vcurrent is greater than v. The alarm-signal may be avisual signal presented at a display at the dashboard in front of the driver, anaudible signal, or a vibration signal, e.g. by inducing vibrations of the steeringwheel, or by combining two or many of these signals. 7 lf the speed supervision module being an integral part of the tachograph, or if thealarm-signal is applied to the tachograph, it would be advantageous to specificallyalert the driver that a registration will be made in the tachograph within a presettime interval that may be 60 seconds, in line with the technique suggested in theabove-referenced EP-2808209 such that the driver may decelerate the vehicle.More specifically, when an alarm-signal is generated a timer is started, and thealarm-signal will be active as long as the current speed is above the maximalallowed speed. The alarm-signal may be a flashing visual sign and be combinedwith an alarm-sound when the preset time interval is about to lapse and the speedstill is too high. For example, the sound may start when 75% of the preset timeinterval has elapsed, which may be 45 seconds if the preset time interval is forexample 60 seconds. The alarm-signal will continue to be active when the currentspeed is above the maximal allowed speed, irrespectively if a registration in thetachograph is made. ln one embodiment the speed supervision module comprises a memory unit 14including maximal allowed speed data and respective related configuration datafor one or many regions/countries. The data may be stored as a table withregions/countries and corresponding speed limitations for various types andconfigurations of vehicles.
There are different ways to detect that a trailer has been attached to a truck. lf the truck has a trailer attached, power detection may be performed at the powerfeeding contacts to the trailer and by a simple electrical measurement a cleardetection is obtained. lt is also possible to provide a detection member in the fifthwheel when the vehicle is a semitrailer tractor. Furthermore, it is also possible toperform pressure measurements of medium in a hydraulic system and/or an airpressure system and to compare a measured pressure value to a thresholdrepresenting an operating pressure level when a trailer is correctly attached to atrack. Thereby, a detection of an attached trailer easily will be made. As an alternative measure it is possible to provide for a manual input by the driver, e.g. 8 via dedicated buttons, or via a touchscreen, that a trailer has been attached to thevehicle.
Figure 3 is a block diagram illustrating another embodiment of the speedsupervision module 2. Herein the module is configured to determine and generatean indication signal 16 including information of the determined maximal allowedspeed v. The indication signal 16 is applied to an indication unit 18 configured toindicate the maximal allowed speed v to a driver of the vehicle when the vehicle isstarted, or when the maximal allowed speed v has been changed. Preferably, theindication signal is a visual signal presented at the indication unit 18, e.g. as a textmessage stating the maximum allowed speed.
Thereby, the driver will be immediately notified about the current maximal allowedspeed for the vehicle.
Figure 4 is a flow diagram of a method according to the present invention to beapplied by a speed supervision module for a vehicle. The speed supervisionmodule is described in detail above and it is referred to that description regardingspecific structural features of the module.
