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 cargo vehicles. In particular, the present disclosure relates to a system and a method for monitoring a cargo space of a vehicle. The present invention also relates to a computer program and a computer program product.

Background

A 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. A cargo or load on a cargo vehicle may include everything from large pallets with goods to small packages with goods. They may be placed separately, or be stacked. Different strategies for loading a cargo vehicle can be applied, and it is often hard for the driver of the vehicle to have full insight in the weight distribution of the load, the sensitivity of the load and thus how the vehicle should be conducted to not jeopardize the integrity of the goods.

During transportation the load may be exposed to acceleration forces in

longitudinal and lateral directions, as well as rotational forces. These forces are particularly noticeable during a starting procedure with heavy acceleration and low gears, as well as at sharp changes of direction. High accelerations in combination with insufficiently secured cargo may lead to damaged goods as well as a risk of personal injury or damage to property in the external environment of the cargo vehicle 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 the cargo of a vehicle. From WO2014133436, US6452487 and US2009138191 systems are known that warns the driver if loose cargo is detected. The loose cargo is detected by means of e.g. a gravity sensor. From WO2014133436 it is known 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 of a 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 velocity that is appropriate for the vehicle, such that the cargo of the vehicle is not compromised or becomes a hazard. The mentioned prior art is arranged to detect changes in the cargo state, but when a change to the cargo has happened it is of course too late to avoid the change.

It is thus an object of the disclosure to alleviate at least some of the drawbacks with the prior art. It is a further object of the disclosure to provide a system and a method that aids the driver in conducting the cargo vehicle in a secure way. It is a further 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 method according to the independent claims, and by the embodiments of the dependent claims.

According to a first aspect, the disclosure relates to a system for monitoring a cargo space of a cargo vehicle. The system includes a device with a processor and a memory, and at least one detector arranged to monitor the cargo space of the cargo vehicle and to generate and send data describing a property of the cargo space and/or cargo in the cargo space to the device. The device is further configured to:

- determine a cargo state of the cargo space based on the property;

- determine a recommended velocity for the cargo vehicle based on the cargo state; and to

- communicate the recommended velocity to the driver of the vehicle. By the system the driver gets support in choosing an appropriate velocity for the vehicle suited for the current cargo. Transportation with the vehicle then becomes more secure and the risk of damaged cargo and injuries can be reduced. Further may the system be used as an educational tool to guide the driver to choose an appropriate 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 current velocity is greater than the recommended velocity, communicate a first action to the driver of the vehicle. The current velocity of the vehicle is thus continuously monitored to detect if the driver does not follow the recommended velocity. If so, the driver may be warned.

According to one embodiment, the device is arranged to again compare the current velocity with the recommended velocity a time period At after the first action was communicated, and if the current velocity is still greater than the recommended velocity, to determine a second action including a restricted driving parameter for a driving unit of the vehicle and communicating the restricted driving parameter to the driving unit, wherein the vehicle is restricted according to the restricted driving parameter. Thus, if the driver neglects the first action, the action is escalated to this second action where at least one function of the vehicle is affected. The second action is thus at least one restricted driving parameter. The restricted 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 first action and/or the second action to a remote computer for tracking of the driver performance. According to one embodiment, the device is configured to determine a cargo state being 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 state being shift of cargo by comparing data of the cargo space and/or cargo in the cargo space obtained at different time points, and determine if a shift of cargo as taken place based on the comparison. According to a second aspect, the disclosure relates to a vehicle including a system according to any of the embodiments as described herein.

According to a third aspect, the disclosure relates to a method for monitoring a cargo space of a cargo vehicle. The cargo vehicle including a device with a processor and a memory, and at least one detector arranged to monitor the cargo space and/or cargo in the cargo space of the cargo vehicle and to send data describing a property of the cargo space and/or cargo in the cargo space to the device. The method includes:

- determining a cargo state of the cargo space based on the property;

- determining a recommended velocity for the vehicle based on the cargo state;

- communicating the recommended velocity to the driver of the vehicle.

The same positive effects as from the system may achieved with the method. According to one embodiment, the method further includes:

- obtaining data of the current velocity of the vehicle;

- comparing the current velocity with the recommended velocity, and if the current velocity is greater than the recommended velocity, communicate a first action to the driver of the vehicle.

According to one embodiment, the method further includes to again compare the current velocity with the recommended velocity a time period At after the first action was communicated, and if the current velocity is still greater than the recommended velocity, to determine a second action including a restricted driving parameter for a driving unit of the vehicle and communicating the restricted driving parameter to the driving unit, wherein the vehicle is restricted according to the restricted driving parameter.

According to one embodiment, the method includes communicating the first action and/or the second action to a remote computer for tracking of the driver performance.

According to one embodiment, the method further including determining a cargo state being 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 method further includes determining a cargo state being shift of cargo by comparing data of the cargo space and/or cargo in the cargo space obtained at different time points, and determine if a shift of cargo as taken place based on the comparison. According to a fourth aspect, the disclosure relates to a computer program P, wherein the computer program P includes a computer program code to cause a device, or a computer connected to the device, to perform the method steps as disclosed herein. According to a fifth aspect, the disclosure relates to a computer program product including a computer program code stored on a non-transitory computer-readable medium to perform the method steps as disclosed herein, when the computer program code is executed by a device or by a computer connected to the device. Preferred embodiments are described in the dependent claims and in the detailed description. Short description of the appended drawings

Detailed description of preferred embodiments of the invention

In Fig. 1 a cargo vehicle in the shape of a truck 1 is illustrated. The truck 1 includes a trailer connected to a powered tractor unit or truck. The trailer may be detachable or non-detachable from the powered tractor unit. The trailer has a cargo space 6 that may be enclosed as illustrated in the Fig. 1 , the trailer is then an 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 to automatically set the velocity of the truck 1 according to a set velocity. The cruise controller is arranged to control the throttle of the vehicle 1 to set the vehicle 1 to a desired set speed, and often also the clutch of the vehicle 1 may be automatically controlled in order to change gear when necessary. The cruise controller may also be arranged to control braking of the vehicle 1 in order to decrease the velocity of the vehicle 1 . The functionality of the cruise controller may be implemented in an Electronic Control Unit (ECU) of the vehicle 1 .

The vehicle 1 is further arranged with a communication unit 4 for communicating information to the driver of the vehicle 1 . The communication unit 4 may be a display or a loud speaker, or even a tactile unit arranged e.g. to vibrate to catch the attention of the driver. The display may be integrated into the dashboard of the cabin of the vehicle 1 or be a Head Up Display (HUD) integrated in the front window. The loud speaker may be integrated into the cabin of the vehicle 1 . The tactile 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 the cargo space 6 of the cargo vehicle 1 . The at least one detector 2 monitors the cargo space 6 and thus also any cargo residing inside the cargo space 6. The at least one detector 2 may be a video camera, may include a laser, a radar, may be a weight detector or any other detector that can produce data that indicates a property of the cargo space 6 and/or cargo in the cargo space 6. Based on the property, a cargo state of any cargo in the cargo space 6 can be determined. The state of the cargo is here also referred to as the state of the cargo space 6. The trailer in Fig. 1 is arranged with two detectors 2, e.g. video cameras 2. Each video camera 2 is arranged to the upper part of the inside of the enclosed trailer, here at oblique opposite positions of the enclosed trailer. The video cameras 2 are directed such that they together can record the state of the cargo space 6, and any changes to the cargo state. Each detector 2 is arranged to generate data that describes at least one property of any cargo in the cargo space 6. A property may e.g. be a visual appearance of the cargo in the cargo space 6 or a weight or weight distribution of the cargo in the cargo space 6 if the detector is a weight detector. The at least one detector 2 is arranged to send the data describing the at least one property to a device 3. The device 3 may be included in a system 5. The device 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 of other communication protocols that may be used are TTP (Time-Triggered

Protocol), Flexray, etc. In that way signals and data described herein may be exchanged between different units, devices, sensors and/or detectors in the vehicle 1 . Signals and data may instead be transferred wirelessly between the different units, devices, sensors and/or detectors. As shown in Fig. 4 the device 3 includes a processor 8 and a memory 9. The processor 8 may include at least one processing unit e.g. a Central Processing Unit (CPU). The memory 9 may include at least one memory unit. A memory unit may include a volatile and/or a non-volatile memory, such as a flash memory or Random Access Memory (RAM). The memory 9 further includes a computer program P including a computer program code to cause the device 3, or a computer connected to the device 3, to perform any of the method steps that will be described in the following. The computer program product includes a computer program code stored on a non-transitory computer-readable medium to perform any of the method steps as disclosed herein when the computer program code is executed 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. The device 3 is further configured to determine a cargo state of the cargo space 6 based 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 door removed to illustrate the cargo 7 inside. The cargo 7 here includes three smaller packages stacked in a pile to the left innermost corner of the trailer, and a larger package located to the right of the trailer closer to the back door opening. Fig. 2 is illustrating an initial cargo state of the vehicle 1 where the vehicle 1 is standing still or has just started and is driving with a very low velocity. The detectors 2 are monitoring the cargo space 6 including the cargo 7 therein and here sends a video stream or pictures of the cargo space 6 to the device 3. The device 3 may also be configured to receive data of the current velocity of the vehicle 1 . The current velocity may be retrieved from a rotating crank shaft or another source in the vehicle 1 , and be readily available on the CAN bus. If the velocity is zero or close to zero within a margin, thus very low, the simultaneous data from the detectors 2 is determined to describe an initial state of the cargo, thus an initial cargo 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 state may be updated if some of the cargo is removed, e.g. for delivery, or if more cargo 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 are not related to unloading or loading of the cargo, e.g. fallen or slidden cargo. The device 3 is configured to compare data describing one or several properties of the cargo space 6 or cargo obtained at different time points, and determine if a shift of cargo as taken place based on the comparison. The detectors 2 continuously monitor the cargo in the cargo space 6 and sends data of the detected property of the cargo and/or cargo space 6 to the device 3. If a difference in the detected data can be determined, e.g. as can be seen in Fig. 3 where the packages 7 on both sides have fallen from the positions they had in Fig. 2, the cargo state of shift of cargo is determined. For example, the device 3 may use object-identification algorithms to identify objects in a picture from a detector 2, and if the object has changed 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 determine a recommended velocity for the cargo vehicle 1 . The characteristics of the determined cargo state may be compared to predefined characteristics related to a recommended velocity of the vehicle 1 , e.g. saved in a table. If for example the cargo state indicates an empty cargo space 6, the recommended velocity may be determined to be the highest allowed velocity for the vehicle. According to another example, if the cargo states indicates high stacked items without support, or other unstable cargo such as high and narrow items, the recommended velocity may be determined to be at most 50 km/h. According to another example, if the cargo states indicates that the cargo is not secured, the recommended velocity may be determined to be at most 50 km/h. According to another example, if the cargo state indicates that the cargo is unequally distributed in the cargo space, the recommended velocity may be determined to be at most 50 km/h. According to another example, if the cargo state shift of cargo has been determined, the recommended velocity may be a set to a lower velocity than the current velocity of the vehicle 1 , or to a predetermined low velocity, e.g. 40 km/h. A characteristic of a 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 restriction along the road. A detector of the vehicle 1 may be arranged to detect any such speed restriction signs, or the maximum velocity of the vehicle 1 along the current road may be predetermined, and the device 3 may based on any of these data be configured to determine an adapted recommended velocity for the vehicle 1 .

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

The determined recommended velocity may also be adapted to the future road topography or a weather parameter. For example if the road is slippery because it is 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 to the driver of the vehicle 1 . The recommended velocity may be communicated to the driver via one or several of the communication devices 4 of the vehicle 1 . The device 3 may be configured to generate a velocity signal describing the

recommended velocity, and send the signal to the one or several communication devices 4. The driver of the vehicle 1 will now know which velocity that is the recommended velocity for the vehicle 1 with the current cargo in the cargo space 6. 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 cruise controller. Alternatively, the device 3 may be configured to set the recommended velocity as the set velocity of the cruise controller.

In order to monitor if the vehicle 1 is conducted according to the recommended velocity, the device 3 is arranged to obtain data of the current velocity of the vehicle 1 . The current velocity may be retrieved e.g. from the rotations of the crank shaft. The device 3 is then configured to compare the current velocity with the recommended velocity, and if the current velocity is greater than the

recommended 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 too fast and should lower the velocity to the recommended velocity. This first action may also be communicated to an operation centre e.g. a computer 1 1 of the operation centre via e.g. wireless communication, together with identification data of the vehicle 1 and/or driver. The vehicle 1 may for the purpose of wireless communication be equipped with a unit for wireless communication (not shown). The first action may there be collected for judgement of the driver, for basis of salary for the driver, for basis of determining the skill of the driver, for determining training needs etc.

The device 3 is further arranged to again compare the current velocity with the recommended velocity a time period At after the first action was communicated to the driver. The time period At may e.g. be 1 , 2, 3, 4, 5 or 10 minutes. If the current velocity is still greater than the recommended velocity, the device 3 is configured to determine a second action including a restricted driving parameter for a driving unit 10 of the vehicle 1 and communicating the restricted driving parameter to the driving unit 10. The vehicle 1 is then restricted according to the restricted driving parameter. The restricted driving parameter may be the recommended velocity or a lower velocity than the recommended velocity, and the driving unit 10 may be the cruise controller. The recommended velocity is then set as the set velocity of the cruise controller. The restricted driving parameter may instead be a restricted gear choice, e.g. only the high gears 1 -3 can be used, and the driving unit 10 the automated gear box of the vehicle 1 . The low gears may then not be allowed to choose. The restricted driving parameter may alternatively be a restricted highest acceleration, and the driving unit 10 is then the ECU controlling the gas throttle valve. The vehicle 1 may be restricted according to a plurality of restricted driving parameters simultaneously. The restricted driving parameter may also be communicated to the operation centre, i.e. the computer 1 1 of the operation centre. The restricted driving parameter may also here be collected for judgement of the driver, for basis of salary for the driver, for basis of determining the skill of the driver, for determining training need etc.

The first action may be the first step in an escalating warning sequence to the driver, and several warnings may be sent to the driver before the second action of restricting one or several driving parameters is made. The driver may also be warned that the one or several driving parameter are going to be restricted, in what 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 1 1 of the operation center, where it may be used for tracking of the driver performance. The computer 1 1 is thus a computer remote from the vehicle 1 . The first and second actions including any warnings etc. may be sent to the operation center directly when they occur, or may be saved in a computer of the vehicle 1 , e.g. a "black box", and sent to the operation center at a later stage, e.g. when the cargo has been delivered and the assignment is completed. The first and second actions including any warnings may be sent to the computer 1 1 as part of an escalating warning. For example, a warning may first be sent to the driver. If the driver neglects the warning, e.g. does not lower the velocity within a certain time period, a second warning may be communicated to the driver and the first and second warnings may be communicated to the computer 1 1 . Instead, only second actions may be communicated to the remote computer 1 1 . As understood, a variety of combinations is here possible. For tracking the driver performance, a judgement of the driver can be made indicating how well the driver is managing the cargo vehicle with the current cargo, 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 for the driver, for determining the skill of the driver or for determining any training need in e.g. techniques for correctly securing cargo or correctly driving with cargo. The judgement and/or any determined actions may be communicated to the driver, either directly or at a later occasion. The judgement may be made by appropriate software algorithms in the remote computer 1 1 , or manually by an operator of the remote computer 1 1 .

The disclosure also relates to a method for monitoring of a cargo space 6 of a cargo 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 9 of the device 3 (Fig. 3). The method may thus be implemented with the above described hardware of the system 5 (Fig. 1 ) in the vehicle 1 . The method includes in a step A1 : determining a cargo state of the cargo space 6 based on the data describing a property of the cargo space 6 and/or cargo in the cargo space 6. This may be done by means of the detectors 2 and the device 3 as previously explained. For example, the method may include determining a cargo state being an initial cargo state of the vehicle 1 determined when the vehicle 1 is standing still or is driving with a very low velocity. The method may also include

determining a cargo state being shift of cargo by comparing data of the cargo space and/or cargo in the cargo space obtained at different time points, and determine if a shift of cargo as taken place based on the comparison. The method further includes in a step A2: determining a recommended velocity for the vehicle 1 based on the cargo state. The recommended velocity may be determined based on an initial cargo state, or on a detected shift of cargo. The method further includes the step A3 of communicating the recommended velocity to the driver of the vehicle 1 . This can be done by any of the described examples of

communication devices 4, or by several communication devices 4 simultaneously. The method may further include obtaining data of the current velocity of the vehicle 1 , comparing the current velocity of the vehicle 1 with the recommended velocity, 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 a recommendation to the driver to slow down the velocity of the vehicle 1 to the recommended velocity. The detectors 2 and the device 3 continuously monitors the velocity of the vehicle 1 , to see if the vehicle 1 is driven faster than the recommended velocity. The method may further include to again compare the current velocity with the recommended velocity a time period At after the first action was communicated. If the current velocity is still greater than the recommended velocity, the device 3 is configured to determine a second action including a restricted driving parameter for the driving unit 10 of the vehicle 1 and communicating the restricted driving parameter to the driving unit 10. The vehicle 1 is then restricted according to the restricted driving parameter.
