Description

System and method for monitoring a cargo space of a vehicle Field of the invention The present disclosure relates to technology for enabling safe driving of cargovehicles. ln particular, the present disclosure relates to a system and a method formonitoring a cargo space of a vehicle. The present invention also relates to acomputer program and a computer program product.

BackgroundA cargo vehicle, for example a truck, is a vehicle that can be loaded with different cargo in order to transport the cargo to one or several places for unloading. Acargo or load on a cargo vehicle may include everything from large pallets withgoods to small packages with goods. They may be placed separately, or bestacked. Different strategies for loading a cargo vehicle can be applied, and it isoften hard for the driver of the vehicle to have full insight in the weight distributionof the load, the sensitivity of the load and thus how the vehicle should beconducted to not jeopardize the integrity of the goods.

During transportation the load may be exposed to acceleration forces inlongitudinal and lateral directions, as well as rotational forces. These forces areparticularly noticeable during a starting procedure with heavy acceleration and lowgears, as well as at sharp changes of direction. High accelerations in combinationwith insufficiently secured cargo may lead to damaged goods as well as a risk ofpersonal injury or damage to property in the external environment of the cargovehicle if the cargo, in the worst case, would fall off the cargo vehicle.

A plurality of documents have been found that include solutions for monitoring thecargo of a vehicle. From WO2014133436, US6452487 and US2009138191systems are known that warns the driver if loose cargo is detected. The loosecargo is detected by means of e.g. a gravity sensor. From WO2014133436 it isknown to change operating parameters of an electronic stability program if loose cargo is detected.

From US2006202809 a system is known for detecting changes in a cargo state ofa delivery vehicle. Changes may be sent to a remote station or to a vehicle operator.

Summary of the invention Especially for unexperienced drivers it may be problematic to know which ve|ocitythat is appropriate for the vehicle, such that the cargo of the vehicle is notcompromised or becomes a hazard. The mentioned prior art is arranged to detectchanges in the cargo state, but when a change to the cargo has happened it is of course too late to avoid the change. lt is thus an object of the disclosure to alleviate at least some of the drawbackswith the prior art. lt is a further object of the disclosure to provide a system and amethod that aids the driver in conducting the cargo vehicle in a secure way. lt is afurther object of the disclosure to provide a system and method that teaches the driver to conduct the cargo vehicle in a secure way.

These objects and others are at least partly achieved by the system and methodaccording to the independent claims, and by the embodiments of the dependent claims.

The system includes a device with a processorand a memory, and at least one detector arranged to monitor the cargo space ofthe cargo vehicle and to generate and send data describing a property of thecargo space and/or cargo in the cargo space to the device. The device is furtherconfigured to: - determine a cargo state of the cargo space based on the property; - determine a recommended ve|ocity for the cargo vehicle based on the cargostate; and to - communicate the recommended ve|ocity to the driver of the vehicle.

By the system the driver gets support in choosing an appropriate velocity for thevehicle suited for the current cargo. Transportation with the vehicle then becomesmore secure and the risk of damaged cargo and injuries can be reduced. Furthermay the system be used as an educational tool to guide the driver to choose anappropriate and thus safe velocity of the vehicle.

According to one embodiment, the device is arranged to: - obtain data of the current velocity of the vehicle; - compare the current velocity with the recommended velocity, and if the currentvelocity is greater than the recommended velocity, communicate a first action tothe driver of the vehicle.

Thus, if the driver neglects the first action, the actionis escalated to this second action where at least one function of the vehicle isaffected. The second action is thus at least one restricted driving parameter. Therestricted driving parameter may be a restriction on the velocity, choice of gear or acceleration.

According to one embodiment, the device is configured to communicate the firstaction and/or the second action to a remote computer for tracking of the driver performance. 4 According to one embodiment, the device is configured to determine a cargo statebeing an initial cargo state of the vehicle determined when the vehicle is standing still or is driving with a very low velocity.

According to one embodiment, the device is configured to determine a cargo statebeing shift of cargo by comparing data of the cargo space and/or cargo in thecargo space obtained at different time points, and determine if a shift of cargo astaken place based on the comparison.

Preferred embodiments are described in the dependent claims and in the detaileddescription. 6 Short description of the appended drawinds Fig. 1 shows a vehicle including a system according to one embodiment.

Fig. 2 shows a cargo space of the vehicle of Fig. 1 in an initial cargo stateaccording to one embodiment.

Fig. 3 shows the cargo space of Fig. 2 in another cargo state according to oneembodiment.

Fig. 4 shows a flowchart of a method according to one embodiment.

Detailed description of preferred embodiments of the invention ln Fig. 1 a cargo vehicle in the shape of a truck 1 is illustrated. The truck 1includes a trailer connected to a powered tractor unit or truck. The trailer may bedetachable or non-detachable from the powered tractor unit. The trailer has acargo space 6 that may be enclosed as illustrated in the Fig. 1, the trailer is thenan enclosed trailer. However, the trailer may instead be an open trailer and the cargo space 6 is then open to the air.

The truck 1 is arranged with a cruise controller (not shown) in order to be able toautomatically set the velocity of the truck 1 according to a set velocity. The cruisecontroller is arranged to control the throttle of the vehicle 1 to set the vehicle 1 to adesired set speed, and often also the clutch of the vehicle 1 may be automaticallycontrolled in order to change gear when necessary. The cruise controller may alsobe arranged to control braking of the vehicle 1 in order to decrease the velocity ofthe vehicle 1. The functionality of the cruise controller may be implemented in anElectronic Control Unit (ECU) of the vehicle 1.

The vehicle 1 is further arranged with a communication unit 4 for communicatinginformation to the driver of the vehicle 1. The communication unit 4 may be adisplay or a loud speaker, or even a tactile unit arranged e.g. to vibrate to catchthe attention of the driver. The display may be integrated into the dashboard of thecabin of the vehicle 1 or be a Head Up Display (HUD) integrated in the frontwindow. The loud speaker may be integrated into the cabin of the vehicle 1. Thetactile unit may be incorporated into the driver”s seat or the steer wheel.

The vehicle 1 is arranged with at least one detector 2 arranged to monitor thecargo space 6 of the cargo vehicle 1. The at least one detector 2 monitors thecargo space 6 and thus also any cargo residing inside the cargo space 6. The atleast one detector 2 may be a video camera, may include a laser, a radar, may bea weight detector or any other detector that can produce data that indicates aproperty of the cargo space 6 and/or cargo in the cargo space 6. Based on theproperty, a cargo state of any cargo in the cargo space 6 can be determined. Thestate of the cargo is here also referred to as the state of the cargo space 6. Thetrailer in Fig. 1 is arranged with two detectors 2, e.g. video cameras 2. Each videocamera 2 is arranged to the upper part of the inside of the enclosed trailer, here atoblique opposite positions of the enclosed trailer. The video cameras 2 aredirected such that they together can record the state of the cargo space 6, andany changes to the cargo state. Each detector 2 is arranged to generate data thatdescribes at least one property of any cargo in the cargo space 6. A property maye.g. be a visual appearance of the cargo in the cargo space 6 or a weight orweight distribution of the cargo in the cargo space 6 if the detector is a weightdetector.

The at least one detector 2 is arranged to send the data describing the at leastone property to a device 3. The device 3 may be included in a system 5. Thedevice 3 may be included into, or may itself be, an Electronic Control Unit (ECU).ECD of the vehicle 1. The vehicle 1 communicates internally between its units,devices, sensors, detectors etc. via a communication bus, for example a CAN-bus(Controller Area Network) which uses a message based protocol. Examples ofother communication protocols that may be used are TTP (Time-TriggeredProtocol), Flexray, etc. ln that way signals and data described herein may beexchanged between different units, devices, sensors and/or detectors in thevehicle 1. Signals and data may instead be transferred wirelessly between the different units, devices, sensors and/or detectors. 8 As shown in Fig. 4 the device 3 includes a processor 8 and a memory 9. Theprocessor 8 may include at least one processing unit e.g. a Central ProcessingUnit (CPU). The memory 9 may include at least one memory unit. A memory unitmay include a volatile and/or a non-volatile memory, such as a flash memory orRandom Access l\/lemory (RAIVI). The memory 9 further includes a computerprogram P including a computer program code to cause the device 3, or acomputer connected to the device 3, to perform any of the method steps that willbe described in the following. The computer program product includes a computerprogram code stored on a non-transitory computer-readable medium to performany of the method steps as disclosed herein when the computer program code isexecuted by the device 3 or by a computer connected to the device 3.

The device 3 is arranged to receive the data from the at least one detector 2. Thedevice 3 is further configured to determine a cargo state of the cargo space 6based on the property of the cargo space 6 and/or cargo in the cargo space 6, as will be explained in the following.

Fig. 2 is illustrating the trailer of the vehicle 1 from behind with the back doorremoved to illustrate the cargo 7 inside. The cargo 7 here includes three smallerpackages stacked in a pile to the left innermost corner of the trailer, and a largerpackage located to the right of the trailer closer to the back door opening. Fig. 2 isillustrating an initial cargo state of the vehicle 1 where the vehicle 1 is standing stillor has just started and is driving with a very low velocity. The detectors 2 aremonitoring the cargo space 6 including the cargo 7 therein and here sends avideo stream or pictures of the cargo space 6 to the device 3. The device 3 mayalso be configured to receive data of the current velocity of the vehicle 1. Thecurrent velocity may be retrieved from a rotating crank shaft or another source inthe vehicle 1, and be readily available on the CAN bus. lf the velocity is zero orclose to zero within a margin, thus very low, the simultaneous data from thedetectors 2 is determined to describe an initial state of the cargo, thus an initialcargo state. This state should thus describe the cargo when it is has not been exposed to any larger forces caused by driving the vehicle 1. This initial cargo 9 state may be updated if some of the cargo is removed, e.g. for delivery, or if morecargo is added.

The device 3 is further configured to determine a cargo state being shift of cargo,if shift of cargo is detected. Shift of cargo may include cargo movements that arenot related to unloading or loading of the cargo, e.g. fallen or slidden cargo. Thedevice 3 is configured to compare data describing one or several properties of thecargo space 6 or cargo obtained at different time points, and determine if a shift ofcargo as taken place based on the comparison. The detectors 2 continuouslymonitor the cargo in the cargo space 6 and sends data of the detected property ofthe cargo and/or cargo space 6 to the device 3. lf a difference in the detected datacan be determined, e.g. as can be seen in Fig. 3 where the packages 7 on bothsides have fallen from the positions they had in Fig. 2, the cargo state of shift ofcargo is determined. For example, the device 3 may use object-identificationalgorithms to identify objects in a picture from a detector 2, and if the object haschanged place since previous pictures, then a shift of load can be determined.According to one embodiment, a shift of cargo can only be detected when the vehicle 1 is driven, that is, it has a velocity that is more than zero.

The device 3 is further configured to use the determined cargo state to determinea recommended velocity for the cargo vehicle 1. The characteristics of thedetermined cargo state may be compared to predefined characteristics related toa recommended velocity of the vehicle 1, e.g. saved in a table. lf for example thecargo state indicates an empty cargo space 6, the recommended velocity may bedetermined to be the highest allowed velocity for the vehicle. According to anotherexample, if the cargo states indicates high stacked items without support, or otherunstable cargo such as high and narrow items, the recommended velocity may bedetermined to be at most 50 km/h. According to another example, if the cargostates indicates that the cargo is not secured, the recommended velocity may bedetermined to be at most 50 km/h. According to another example, if the cargostate indicates that the cargo is unequally distributed in the cargo space, therecommended velocity may be determined to be at most 50 km/h. According to lO another example, if the cargo state shift of cargo has been determined, therecommended velocity may be a set to a lower velocity than the current velocity ofthe vehicle 1, or to a predetermined low velocity, e.g. 40 km/h. A characteristic ofa determined cargo state may be the same as a property of the cargo or cargo space 6.

The determined recommended velocity may be adapted to any speed restrictionalong the road. A detector of the vehicle 1 may be arranged to detect any suchspeed restriction signs, or the maximum velocity of the vehicle 1 along the currentroad may be predetermined, and the device 3 may based on any of these data beconfigured to determine an adapted recommended velocity for the vehicle 1.

The determined recommended velocity may alternatively or also be adapted toany predetermined velocity of the vehicle 1 set e.g. by the hauler, the driver, orany other person or system. Especially if the predetermined velocity is lower thanthe determined recommended velocity, the device 3 is configured to adapt thedetermined recommended velocity to the predetermined velocity.

The determined recommended velocity may also be adapted to the future roadtopography or a weather parameter. For example if the road is slippery because itis raining, the recommended velocity may be set to a lower velocity than already determined.

The device 3 is further configured to communicate the recommended velocity tothe driver of the vehicle 1. The recommended velocity may be communicated tothe driver via one or several of the communication devices 4 of the vehicle 1. Thedevice 3 may be configured to generate a velocity signal describing therecommended velocity, and send the signal to the one or several communicationdevices 4. The driver of the vehicle 1 will now know which velocity that is therecommended velocity for the vehicle 1 with the current cargo in the cargo space6. ll The driver now has the possibility to drive according to the recommended velocity.The driver may self set the recommended velocity as the set velocity of the cruisecontroller. Alternatively, the device 3 may be configured to set the recommendedvelocity as the set velocity of the cruise controller. ln order to monitor if the vehicle 1 is conducted according to the recommendedvelocity, the device 3 is arranged to obtain data of the current velocity of thevehicle 1. The current velocity may be retrieved e.g. from the rotations of thecrank shaft. The device 3 is then configured to compare the current velocity withthe recommended velocity, and if the current velocity is greater than therecommended velocity, to communicate a first action to the driver of the vehicle 1.The first action may be e.g. a warning to the driver that the driver is driving toofast and should lower the velocity to the recommended velocity. This first actionmay also be communicated to an operation centre e.g. a computer 11 of theoperation centre via e.g. wireless communication, together with identification dataof the vehicle 1 and/or driver. The vehicle 1 may for the purpose of wirelesscommunication be equipped with a unit for wireless communication (not shown).The first action may there be collected for judgement of the driver, for basis ofsalary for the driver, for basis of determining the skill of the driver, for determiningtraining needs etc.

The device 3 is further arranged to again compare the current velocity with therecommended velocity a time period At after the first action was communicated tothe driver. The time period At may e.g. be 1, 2, 3, 4, 5 or 10 minutes. lf the currentvelocity is still greater than the recommended velocity, the device 3 is configuredto determine a second action including a restricted driving parameter for a drivingunit 10 of the vehicle 1 and communicating the restricted driving parameter to thedriving unit 10. The vehicle 1 is then restricted according to the restricted drivingparameter. The restricted driving parameter may be the recommended velocity ora lower velocity than the recommended velocity, and the driving unit 10 may bethe cruise controller. The recommended velocity is then set as the set velocity ofthe cruise controller. The restricted driving parameter may instead be a restricted 12 gear choice, e.g. only the high gears 1-3 can be used, and the driving unit 10 theautomated gear box of the vehicle 1. The low gears may then not be allowed tochoose. The restricted driving parameter may alternatively be a restricted highestacceleration, and the driving unit 10 is then the ECU controlling the gas throttlevalve. The vehicle 1 may be restricted according to a plurality of restricted drivingparameters simultaneously. The restricted driving parameter may also becommunicated to the operation centre, i.e. the computer 11 of the operationcentre. The restricted driving parameter may also here be collected for judgementof the driver, for basis of salary for the driver, for basis of determining the skill ofthe driver, for determining training need etc.

The first action may be the first step in an escalating warning sequence to thedriver, and several warnings may be sent to the driver before the second action ofrestricting one or several driving parameters is made. The driver may also bewarned that the one or several driving parameter are going to be restricted, inwhat way and when. This may be communicated to the driver via any of the communication devices 4 in the vehicle 1.

The first and second actions including any warnings may, as has been explained,be sent to a computer 11 of the operation center, where it may be used fortracking of the driver performance. The computer 11 is thus a computer remotefrom the vehicle 1. The first and second actions including any warnings etc. maybe sent to the operation center directly when they occur, or may be saved in acomputer of the vehicle 1, e.g. a “black box”, and sent to the operation center at alater stage, e.g. when the cargo has been delivered and the assignment iscompleted. The first and second actions including any warnings may be sent tothe computer 11 as part of an escalating warning. For example, a warning mayfirst be sent to the driver. lf the driver neglects the warning, e.g. does not lowerthe velocity within a certain time period, a second warning may be communicatedto the driver and the first and second warnings may be communicated to thecomputer 11. lnstead, only second actions may be communicated to the remotecomputer 11. As understood, a variety of combinations is here possible. 13 For tracking the driver performance, a judgement of the driver can be madeindicating how well the driver is managing the cargo vehicle with the currentcargo, based on any or all of the first and second actions including any warnings.This judgement may be one basis e.g. for actions such as determining salary forthe driver, for determining the skill of the driver or for determining any trainingneed in e.g. techniques for correctly securing cargo or correctly driving with cargo.The judgement and/or any determined actions may be communicated to thedriver, either directly or at a later occasion. The judgement may be made byappropriate software algorithms in the remote computer 11, or manually by anoperator of the remote computer 11.

The disclosure also relates to a method for monitoring of a cargo space 6 of acargo vehicle 1, which will now be described with reference to the flowchart in Fig.5. The method may be implemented as program code and saved in the memory 9of the device 3 (Fig. 3). The method may thus be implemented with the abovedescribed hardware of the system 5 (Fig. 1) in the vehicle 1. The method includesin a step A1 : determining a cargo state of the cargo space 6 based on the datadescribing a property of the cargo space 6 and/or cargo in the cargo space 6. Thismay be done by means of the detectors 2 and the device 3 as previouslyexplained. For example, the method may include determining a cargo state beingan initial cargo state of the vehicle 1 determined when the vehicle 1 is standingstill or is driving with a very low velocity. The method may also includedetermining a cargo state being shift of cargo by comparing data of the cargospace and/or cargo in the cargo space obtained at different time points, anddetermine if a shift of cargo as taken place based on the comparison. The methodfurther includes in a step A2: determining a recommended velocity for the vehicle1 based on the cargo state. The recommended velocity may be determined basedon an initial cargo state, or on a detected shift of cargo. The method furtherincludes the step A3 of communicating the recommended velocity to the driver ofthe vehicle 1. This can be done by any of the described examples of communication devices 4, or by several communication devices 4 simultaneously. 14 The method may further include obtaining data of the current velocity of thevehicle 1, comparing the current velocity of the vehicle 1 with the recommendedvelocity, and if the current velocity is greater than the recommended velocity,communicate a first action to the driver of the vehicle 1. The first action may be arecommendation to the driver to slow down the velocity of the vehicle 1 to therecommended velocity. The detectors 2 and the device 3 continuously monitorsthe velocity of the vehicle 1, to see if the vehicle 1 is driven faster than therecommended velocity. The method may further include to again compare thecurrent velocity with the recommended velocity a time period At after the firstaction was communicated. lf the current velocity is still greater than therecommended velocity, the device 3 is configured to determine a second actionincluding a restricted driving parameter for the driving unit 10 of the vehicle 1 andcommunicating the restricted driving parameter to the driving unit 10. The vehicle1 is then restricted according to the restricted driving parameter.

The present invention is not limited to the above-described preferredembodiments. Various alternatives, modifications and equivalents may be used.Therefore, the above embodiments should not be taken as limiting the scope ofthe invention, which is defined by the appending claims.
