Description

The invention relates to a system for determining and checking the payload of a single-track motor vehicle.

In the case of single-track motor vehicles, which can in particular be motorcycles, the payload, particularly determined by luggage, and its distribution on the vehicle are highly relevant to driving behavior.

In the prior art, it has often only been provided to adapt the motor vehicle to a payload, for example by adjusting its spring-damper system, without monitoring the payload or its distribution.

In motor vehicles in general and, for example, according to the Scripture DE 10 2014 214 926 A1 In addition, the known system often only records the load of passengers and, if necessary, secondarily the load of luggage. Comparatively complex weighing systems are then provided for this purpose, which often cannot take into account the arrangement of the luggage on a single-lane motor vehicle.

In addition, items of luggage or containers for single-track motor vehicles usually have a maximum payload or a maximum weight and/or a maximum speed, which may not be exceeded, since the containers are only designed and approved up to these respective limit values.

The invention is therefore based on the object of overcoming the aforementioned disadvantages and of providing a system for determining and testing or monitoring the payload of a single-track motor vehicle, through which an impermissible payload can be prevented in a simple manner.

This task is achieved by the combination of features according to claim 1.

According to the invention, a system for determining and checking the payload of a single-track motor vehicle is therefore proposed, the motor vehicle preferably being a motorcycle and the payload preferably being a payload of the motor vehicle determined by luggage. The system accordingly includes the single-track motor vehicle, which has at least one mechanical interface for the releasable attachment of a container to the motor vehicle. The at least one container can in particular be pieces of luggage intended for attachment to the vehicle, such as motorcycle cases or top cases. The system further comprises at least one container attached to one of the interfaces on the motor vehicle, which has a storage space for holding objects that determine the payload, at least one sensor for determining a weight of objects stored in the storage space, and an evaluation unit, which is preferably in the Motor vehicle is integrated and designed to compare the weight determined by the at least one sensor with at least one predetermined limit value and to generate a visual and / or acoustic warning if the limit value is exceeded.

If the vehicle or single-track motor vehicle only has one interface to which the container is attached, or the vehicle has several interfaces, with a container being attached to only one of the interfaces, the evaluation unit can calculate the weight of the container corresponding to this one container Compare the load contained in the container with the at least one limit value.

If the vehicle has several interfaces and a container is provided at several of these interfaces, the weight determined by a respective sensor for a respective container can be compared with a limit value specific to each container and/or interface. Additionally or alternatively, the individual weights of the loads of some or all containers can be added up and compared with an overall limit value.

If several interfaces are also provided, with a container being attached to the vehicle at at least one of the interfaces, the permissibility of the load distribution on the vehicle can be determined from the weight of the load of this container and a position of the interface on the vehicle to which the container is attached .

The limit value, the specific limit values and/or the overall limit value of the interfaces and/or the containers can be stored in the evaluation unit, the interfaces or the containers.

If the limit value or one of the limit values is exceeded, a visual and/or acoustic warning is triggered, which can be output, for example, on a vehicle instrument cluster or another optical display unit.

The system proposed according to the invention can accordingly prevent an impermissibly high load on the vehicle and/or the containers. If several interfaces are also provided, each with a container, an impermissible load distribution on the vehicle can be detected and displayed to a user or driver.

An advantageous variant provides that the at least one sensor is provided on or integrated into a base plate of the at least one container, which determines a base of the storage space. The floor is preferably understood to be the wall or plate of the storage space, which faces the ground in a neutral position or when used as intended. The sensor is also designed to determine a weight force acting on the base plate by the objects and thereby the weight of the objects.

Furthermore, it can be provided that the container has an outer housing and a trough that determines the storage space and is decoupled from the outer housing and that the base plate forms a section of the trough. What is meant by decoupled is that the tub can move at least to a limited extent relative to the outer housing, so that the weight of the objects in the tub can be determined via the sensor through the relative movement of the tub to the outer housing.

As an alternative to the sensor provided in the container, at least one sensor can be provided at each of the mechanical interfaces, which is designed to detect a weight force that acts on the respective interface from a respective container that can be attached or attached to the respective interface, and thus that To record the weight of the container with the items stored in it. In particular, if the weight of the containers is known in advance, the weight of the objects in the container can be easily calculated. Alternatively, the limit can also take into account the weight of the containers.

In an advantageous embodiment variant, the single-track motor vehicle has a first mechanical interface and a second mechanical interface for releasably attaching a container to the motor vehicle. In particular, it is provided that the two interfaces or the two containers are arranged opposite one another in the transverse direction of the vehicle, i.e. transversely to the longitudinal direction of the vehicle. Accordingly, a first container is attached to the first mechanical interface and a second container is attached to the second mechanical interface. Furthermore, a first sensor is provided for determining a first weight of objects stored in the storage space of the first container and a second sensor for determining a second weight of objects stored in the storage space of the second container. In this variant, the evaluation unit is also designed to compare the first weight with the second weight and to issue a visual and/or acoustic warning in the event of a deviation that exceeds a tolerance or a tolerance limit value, so that an unequal load distribution on the vehicle is prevented can.

Such an evaluation is optionally also possible if a container is only attached to one of the two opposite interfaces, whereby a predetermined weight of, for example, 0 kg can be assumed for the free interface to which no container is attached.

Furthermore, it can also be provided that the evaluation unit is designed to detect which mechanical interfaces containers are attached to.

The containers can each be, for example, a top case, a suitcase or a bag, which preferably have connection sections corresponding to the mechanical interface.

The at least one sensor can also be a force sensor or a pressure sensor or a strain gauge or a load cell.

Furthermore, the system can have an acceleration sensor for determining an orientation of the at least one container or generally of the single-track motor vehicle and thus of the containers attached to it, wherein the at least one sensor for determining the weight is designed to increase the weight in a predetermined orientation of the at least one container determine. Alternatively, the evaluation unit can be designed to compare the weight determined by the at least one sensor with a predetermined limit value only in the predetermined orientation of the at least one container. This is to ensure that the weight or the measurement in general is not distorted by, for example, an inclined position of the vehicle. Accordingly, the vertical axis of the vehicle in the predetermined orientation is preferably parallel to the acceleration due to gravity or at least approximately parallel to the acceleration due to gravity.

In addition, the system can have a speed sensor for determining a speed of the motor vehicle, which can also be integrated in the vehicle. The evaluation unit is then designed to compare the speed of the motor vehicle with a maximum speed predetermined for the weight of the payload and to generate a visual and/or acoustic warning or to display it to the driver if the maximum speed is exceeded. Alternatively or additionally, the maximum speed can depend on the type of container and can be stored, for example, in or on the container or in the evaluation unit.

Furthermore, it can be provided that the predetermined limit value or the respective specific limit value of the container and / or the interfaces and / or the tolerance limit value and / or the overall limit value and / or the maximum speed permissible for the respective container in one Data storage provided in the respective container is stored, the data storage can also be, for example, a QR or bar code or another optically readable code. A reading device for reading out the data memory is then provided on the motor vehicle and in particular at the mechanical interfaces, which is designed to read the limit value from the data memory and transmit it to the evaluation unit.

The features disclosed above can be combined in any way, as long as this is technically possible and they do not contradict each other.

• 2 zwei einander gegenüberliegende Behälter.

Other advantageous developments of the invention are characterized in the subclaims or are shown in more detail below together with the description of the preferred embodiment of the invention with reference to the figures. Show it:

• 1 a single-track motor vehicle with containers attached;
• 2 two containers opposite each other.

The figures are exemplary schematic. The same reference numbers in the figures indicate the same functional and/or structural features.

In 1 a system 1 with a motorcycle is shown as a single-track motor vehicle 2, to which several containers 4 are releasably attached via a respective interface 3 of the motor vehicle 2. Due to the side view of the vehicle 2 shown, so that a plane is visible in which the longitudinal axis X and the vertical axis Z of the vehicle 2 lie, a motorcycle case shown on the side of the vehicle 2 is one of the containers 4 and one shown at the top of the vehicle 2 Top case visible as another container 4.

The system 1 according to the invention is intended in particular to prevent overloading of the containers 4 and also of the interfaces 3 via which the containers 4 are attached to the vehicle 2. This can also prevent the vehicle from being overloaded in terms of the permissible weight of the luggage.

For this purpose, in the advantageous embodiment variant shown, a sensor 7 is provided in each of the containers 4 for determining the weight of the objects 6, which are each arranged in the storage space 5 determined by the containers 4.

The weight or the weight force of the objects 6 act in the respective storage space 5 on a base plate 9 of the respective container 4, with the sensor 7 being integrated into the base plate 9 or arranged on it, so that the sensor 7 detects the effects caused by the objects 6 acting weight force or its weight can be determined.

The sensors 7 are each connected to the evaluation unit 8 via a communication interface provided for this purpose, which is provided in the vehicle 2 and can also be integrated in a control unit of the vehicle 2.

The evaluation unit 8 is designed in the present case to compare the weights determined by the sensors 7 with a respective assigned specific limit value, whereby if the specific limit value, i.e. container-dependent limit value, is exceeded, it is indicated via the combination instrument 12 that one of the containers 4 is overloaded. Furthermore, the individual weights determined by the sensors 7 are summed up by the evaluation unit 8 and compared with an overall limit value. If the sum of the individual weights exceeds the overall limit value, this excess can also be displayed via the instrument cluster 12.

In 2 is one opposite the 1 Rotated view is shown, so that a plane is visible in which the vertical axis Z and the transverse axis Y of the vehicle 2 lie. This can be a simplified representation of the in 1 system 1 shown.

In particular, two containers 4 lying opposite each other (a first container) are visible 4A and a second container 4B), each of which is releasably held or releasably attached to the vehicle 2 via an interface 3 (a first interface 3A and a second interface 3B).

According to 2 the system 1 is designed to monitor a load distribution of the load determined by the luggage or objects 6. For this purpose, a first sensor 7A is provided in the first container 4A and a second sensor 7B is provided in the second container 4B.

The containers 4A, 4B each have a trough 11, which are decoupled from a respective outer housing 10 of the respective container 4A, 4B in such a way that the trough 11 each move at least slightly relative to the outer housing 10 and a weight or a weight of each Objects 6 arranged in the tub 11 can act on the respective sensor 7A, 7B via the base plate 9 of the tub 11.

Accordingly, the first sensor 7A determines a first weight of the objects 6 in the first container 4A and the second sensor 7B determines a second weight of the objects 6 in the second container 4B, the first and second weights being transmitted to the evaluation unit 8.

The evaluation unit 8 compares the first weight and the second weight, for example by subtracting the weights, and thus determines a deviation of the weights from one another. If the deviation is small and preferably less than 0.5 kg, the load distribution is approximately balanced and therefore permissible. However, if the deviation exceeds a permissible tolerance, i.e. a tolerance or distribution limit of, for example, 5 kg, the load distribution is impermissible and a warning is displayed to the driver, for example via the instrument cluster 12.

Preferably, the weights are determined by the sensors 7A, 7B only in a predetermined orientation in order to avoid measurement errors. For this purpose, an acceleration sensor 13 can determine the orientation of the vehicle 2, whereby the vehicle vertical axis Z must be at least approximately parallel to the effective gravitational acceleration g, so that the weight forces of the objects 6 can be completely detected via the sensors 7, 7A, 7B.

The implementation of the invention is not limited to the preferred exemplary embodiments given above. Rather, a number of variants are conceivable, which make use of the solution presented even in fundamentally different designs.
