Abstract
The present disclosure relates to a device for attachment to a vehicle, an assembly of a device and a vehicle, and a vehicle for attachment of a device thereto. Embodiments of the present disclosure relate to providing an improvement relative to the prior art. Thereby, generally, the device is enabled to transmit processed or raw signals from its distance sensor to the vehicle and the vehicle is capable of accepting said signals, whereby the sounds or images associated with or generated based on these signals are fed into a vehicle's integrated system for display of a schematic or camera image on the integrated display, thus obviating a need for an additional display.
Description
DEVICE FOR ATTACHMENT TO A VEHICLE, AN ASSEMBLY OF A VEHICLE AND A DEVICE, AND A VEHICLE FOR ATTACHMENT OF A DEVICE THERETO
The present disclosure relates to a device for attachment to a vehicle, an assembly of a device and a vehicle, and a vehicle for attachment of a device thereto.
In the relevant technical field of the prior art it is known to provide at least one distance sensor on a device, such as a trailer, a bicycle carrier and a box or coffer. Such devices are configured for attachment to for instance a rear hitch of a vehicle carrying or dragging such devices.
If a vehicle, such as a car, van, truck or the like, has at least one distance sensor, for instance integrated in a rear bumper or fender, a dashboard integrated display can supply a driver with a presentation of a rear view image indicating obstacles, if any, located behind the vehicle based on signals from the at least one vehicle mounted distance sensor. However, with the device carried or dragged by the vehicle, there’s no free line of sight for the car integrated distance sensor, and the display will continuously and annoyingly present a proximity alarm corresponding with an obstacle, caused by the device. To date, vehicle manufacturers have only implemented detection if a device is carried or dragged by the vehicle, and to switch of the at least one distance sensor and/or the display. Such measures are based on detection of for instance connection of a power and control cable of the dragged or carried device to a power and control connector of the vehicle.
Superfluously, it is noted here that the display can comprise any one or more than one of a sound generator, a graphic image display to present a schematic positional representation of obstacles in relation to a rear side of the vehicle, and a camera display if the vehicle is provided with a backing-up camera.
In the relevant field, also add-on systems are known.
In one known configuration such an add-on system may comprise a camera and screen, where the camera is to be mounted at, on or to a rear side of the vehicle, if the vehicle does not have any proximity detection or camera image system. This is known to help camper or RV drivers to manoeuvre, when backing-up the camper or RV, which is often longer than a length of a vehicle that the drivers of such campers and RV’s are accustomed to. Systems are also known to comprise acoustic sensor for distance determination relative to obstacles and the like. The same benefit can be realised for drivers of a regular car, truck or vehicle in general, when an appended device (carried or dragged) is attached to the car, even if the car has an integrated distance system, such as park distance control (PDS). When images from the camera or based on signals from acoustic sensors are to be displayed on a screen to be arranged on the vehicle’s dashboard, such a screen is known to reduce a field of view in forward direction for the driver.
The present disclosure relates to providing an improvement relative to the prior art in relation to any of the above discussed respects, or to any other not-mentioned respect, through assemblies of features defined in the appended independent claims.
Thereby, generally, the device is enabled to transmit processed or raw signals from its distance sensor to the vehicle, and the vehicle is capable of accepting said signals, whereby the sounds or images associated with or generated based on these signals are fed into a vehicle’s integrated system for display of a schematic or camera image on the integrated display, thus obviating a need for an additional display.
This may require adaptation to the vehicle, or to the device to be carried or dragged by the vehicle, or to both. Consequently the present disclosure may be embodied in the device to be carried/dragged by the vehicle, in the vehicle carrying or dragging the device, or in both, and consequently appended independent claims are directed at each of these possible embodiments.
Based on the above general indications of the breadth and width of the present disclosure in terms of the expressions and definitions according to the appended independent claims to indicate a scope of protection for the present disclosure, it should immediately be evident that a multitude of potential and possibly even preferred embodiments lie therein. These may be described below in an embodiment description, referring to appended drawings, and/or may be defined in appended dependent claims. However, the present disclosure is only restricted by the definitions and expressions according to the appended independent claims, and may include obvious equivalents for as yet unforeseen alternative embodiments, whereas the following indications of preferred embodiments are by no means provided or should by no means be interpreted as limiting on the scope of the present disclosure.
In a preferred embodiment, the device may comprise a wireless transmitter configured to transmit, to the vehicle, signals from the at least one rearward oriented distance sensor, and the vehicle may comprise a wireless receiver configured to receive, from the device, signals from the at least one rearward oriented distance sensor of the device.
In an alternative preferred embodiment, the device may comprise rearward oriented lighting and a power and control cable for connection with the vehicle, the power and control cable comprises at least a data transmission conductor configured for transmission to the vehicle of signals from the at least one rearward oriented distance sensor, whereas the vehicle may further comprising a power and control connector for power supply to and control over rearward oriented lighting of the device, wherein the power and control connector comprises at least a data transmission conductor configured for receipt from the device of signals from the at least one rearward oriented distance sensor of the device. Alternative wired configurations are also to be considered to lie with the scope of the present disclosure.
In any such a wired embodiment the device may be such that the power and control cable is configured to carry power for the least one rearward oriented distance sensor from the vehicle to the device, and the vehicle may be such that the power and control connector is configured to carry power for the least one rearward oriented distance sensor from the vehicle to the device.
In such a device, a lighting power conductor of the cable may comprise a branch with a leg connecting to the at least one rearward oriented distance sensor.
In an alternative preferred embodiment, the device may be such that the power and control cable is a thirteen pole cable, and the vehicle may be such that the power and control connector is a thirteen pole connector.
In any wired configuration, the device may be such that a CAN bus is integrated into the power and control cable, whereas a vehicle may be such that a CAN bus is integrated into the power and control connector.
The at least one rearward oriented distance sensor may comprise a backing-up camera.
The above described features may equally well be employed in a combination of a vehicle and a device to be carried or dragged by the vehicle, designated herein as an assembly thereof.
After the above description in more generic terms and expressions, following the terms and expressions used in the appended claims, herein below a detailed embodiment description will follow, referring to the appended drawing, in which:
Figure 1 shows a perspective view of a device, a care and consequently also an assembly thereof; and
Figure 2 shows a schematic, partially broken open view of the embodiments of figure 1.
Figure 1 shows trailer 1 as an embodiment of a device according to the present disclosure. Alternative embodiments could relate to a bicycle carrier, a coffer or a box, or the like which can be carried on or dragged by hitch 4. Although a trailer would be dragged along while coupled to such a hitch 4, a bicycle carrier or coffer or box could be configured to be carried on such a hitch 4. Hitch 4 can be arranged to or on car 2, forming an embodiment of the vehicle according to the present disclosure. Alternatives of vehicles, relative to the disclosed car, can be a truck, a van or the like. The present disclosure could even relate to a motor cycle with a trailer. In a coupled state, trailer 1 and car 2 form an assembly 3.
Car 2 is equipped with either or both of camera 5 and acoustic distance sensor 6. A plurality of acoustic distance sensors 6 can be provided. Camera 5 and/or acoustic distance sensors 6 can be connected to controller 12 in figure 2, to process data signals therefrom and generate auditory or image information, for example for presentation on display 13, which is integrated into dashboard 14 of car 2, next to for example a steering wheel 15.
Likewise, trailer 1 is also equipped with either or both of camera 7 and acoustic distance sensor 8. A plurality of acoustic distance sensors eight can be provided at the rear side of trailer 1.
Further, trailer 1 comprises rear lights 9, which can comprise a backup light, brake light and a constantly illuminating light, or the like.
Normally, trailer 1 will receive electrical energy from car 2 via a cable 10. Such a cable 10 will normally form part of the trailer 1, whereas car 2 will normally be equipped with a connector 11 for electrical connection of trailer 1 to car 2. Connector 11 will normally be driven by the controller 12 in figure 2, to selectively illuminate any number of the rear lights 9 necessary under prevailing circumstances. For example, a rear light for backing up should be illuminated, when a driver in car 2 is backing up the assembly 3 in a rearward direction. Brake lights should illuminate, when the driver is slowing down.
By extending the number of poles of cable 10 and connector 11, such a wired electrical connection between trailer 1 and car 2 can serve to provide power to acoustic distance sensors 8 and/or camera 7 at the rear side of trailer 1. Additionally or alternatively, such an extension of the number of poles of cable 10 and connector 11 can provide an ample number of conductors for transmission of data from camera 7 and/or distance sensors 8 to controller 12 from trailer 1 to car 2. Controller 12 can form a kind of central controller of car 2. Alternatively, separate controllers can be provided for rear lighting 9 of trailer 1 and for processing data received from distance sensors 8 and/or camera 7 of trailer 1. Preferably, controller 12 is in any case the same controller used for processing data signals from acoustic distance sensor 6 and/or from camera 5.
In a situation, where trailer 1 is coupled with hitch 4, it will be necessary to also connector cable 10 to connector 11; otherwise rear lights 9 won't work. Such a connection is detectable, and can result in the controller 12 disregarding signals from camera 5 and/or distance sensors 6. On the other hand in a possible embodiment, distance signals indicating a distance between car 2 and trailer 1 can provide an indication of an angle between an orientation of car 2 and orientation of trailer 1. When backing up, a driver can thereby be provided with trajectory information, expected to result from such a detected angle.
Regardless of whether distance indicating signals from distance sensors 6 or image signals from camera 5 are disregarded by controller 12, when trailer 1 is coupled with car 2, controller 12 can be configured to select distance indicating signals from distance sensors 8 or image signals from camera 7 for presentation on the car’s display 13 in dashboard 14, thus obviating the need for any additional screen, to be placed on dashboard 14.
In case, where display 13 is configured to represent, under control of controller 12, a schematic or graphic representation of distances relative to obstacles, normally signals from distance sensors 6, 8 will be employed by controller 12. However, also images from anyone of cameras 5, 7 can yield, after appropriate image processing, distance information for such a graphic representation of distances relative to obstacles. However, when image signals from a camera are available, it seems preferable to present camera images on display 13.
Cable 10 and connector 11 are preferably upgraded, relative to conventional cables and connectors, to comprise conductors or the like for transmission of distance signals from distance sensors 8 and/or image signals from camera 7. This could be achieved by simply adding conductors, for example by upgrading from a seven pole cable and connector to a 13 pole cable and connector, but additionally or alternatively a CAN bus could be incorporated into cable 10 and connector 11. Within the framework of the present disclosure, it is even not excluded that a separate cable in addition to power and control cable 10 is employed for transmission of distance and/or image signals. In contrast, an integrated embodiment with additional conductors and/or an arbitrary type of data bus for information transmission is considered preferable. Even if a separate cable is employed in addition to power and control cable 10, then such an additional separate cable could be dedicated to data transport, whereas power and control cable 10 could still be employed to supply electrical power to distance sensors 8 and/or camera 7 at the rear of trailer 1. In the schematic representation of figure 2, a node 17 forming a branch is exhibited, where legs 16 split off from cable 10 to enable power supply to camera 7 and/or distance sensors 8.
From the indicated possibilities in the latter portions of the above description it is already immediately evident to the skilled person, that many additional and alternative embodiments are conceivable and readily implementable, relative to the details and particulars of the embodiments that are explicitly shown and described in the appended drawing and the embodiment description above. On the basis of this insight, it is also already self evident, that embodiments of the present disclosure are by no means limited or restricted to any particular embodiment from the appended drawing or the above embodiment description, and that all conceivable alternatives, also for specific features in the appended independent claims, lie within the scope of the present disclosure as defined in the appended independent claims.
