Description
Technical Field
The invention relates to the technical field of car networking, in particular to a bearing device of V2X equipment and an automobile.
Background
Currently, with the development of autonomous driving technology and car networking technology, autonomous fleets of vehicles can travel together in close and safe fashion. An autonomous vehicle fleet, i.e. all vehicles of a vehicle fleet, have the ability to autonomously drive and, under the lead of the leading vehicle, the following vehicles follow each other closely in turn. The interval of 10 meters or less before and after the automatic driving fleet can be kept at the speed of 100km/h, so that the efficiency of the vehicle can be improved, and the traffic jam, pollution and passenger pressure can be reduced. In addition to the requirement for each vehicle to be autonomous, vehicle-to-vehicle communication is a key technology for implementing autonomous fleet vehicles, and its communication performance directly affects the minimum separation distance that can be achieved between fleets of vehicles. V2X (Vehicle to X, information interaction from Vehicle to outside) is an efficient wireless communication technology, and can realize identification and bidirectional communication of moving objects in high-speed motion in a specific small area. For example, V2X can realize wireless communication with end-to-end delay of less than 100ms of maximum 300m to 1000m, is not obstructed by line of sight, is a relatively mature vehicle-to-vehicle communication scheme, and can be applied to an automatic driving vehicle fleet.
To apply the V2X technology, it is necessary to install the V2X device inside the vehicle, and as shown in fig. 1, it is necessary to install the V2X antenna 10 on the top of the head of the vehicle 11. However, for trucks, especially container trucks, the rear wall box 12 is mostly made of metal, which can cause metal shielding, and the shielding of the transmission and reception of the wireless signals of the V2X antenna is particularly obvious. If the height of the V2X antenna is increased, there may be a risk of being ultra high (e.g., typical container trucks have a roof height of 3.8m, while typical height limits are typically 4 m).

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to make the present invention better understood by those skilled in the art, some concepts appearing in the embodiments of the present invention are explained below:
V2X: vehicle to X, meaning Vehicle to Everything, Vehicle to outside information exchange. The method is a key technology of a future intelligent transportation system. It enables communication between cars, between cars and base stations, and between base stations. Therefore, a series of traffic information such as real-time road conditions, road information, pedestrian information and the like is obtained, so that the driving safety is improved, the congestion is reduced, the traffic efficiency is improved, and the vehicle-mounted entertainment information is provided.
CAN bus: controller Area Network, a widely used field bus.
In the process of implementing the embodiment of the invention, the inventor finds that the V2X antenna of the current V2X equipment is generally installed on the top of a vehicle, the signals transmitted and received by the antenna are easily blocked by a metal container, and the height limit requirement of the vehicle cannot be met by increasing the length of the V2X antenna on the top of the vehicle. Therefore, in some current application scenarios, for example, in an automatic driving fleet, V2X devices are relatively relied on among vehicles, and if signals transmitted and received by the V2X antenna are blocked, communication delay and communication packet loss among vehicles are easily caused, and accidents are easily caused during automatic driving. Therefore, it is important to solve the problem of communication signals between V2X devices.
In order to solve the above-mentioned drawbacks, as shown in fig. 2, an embodiment of the present invention provides a carrier 20 of a V2X apparatus, including: V2X shell 21 and bracket 22; the bracket 22 connects the V2X casing 21 with the vehicle head 31 of the vehicle to fix the V2X casing 21 to the side of the vehicle head 31; the V2X device 40 is disposed inside the V2X housing 21; the V2X device 40 is connected with a V2X antenna 41, the V2X antenna 41 extending outside the V2X housing 21; the V2X device 40 is connected to the power supply system device 32 and the bus system device 33 inside the vehicle through the connection line 42.
Specifically, as shown in fig. 3, the V2X casing 21 may be a casing 34 of a rear view mirror of a vehicle, and a reflective mirror 35 is provided on a rear side of the casing 34 of the rear view mirror of the vehicle. Sufficient space can be reserved in the casing 34 of the vehicle rear view mirror so that the V2X device 40 can be placed therein, so that the casing 34 of the vehicle rear view mirror serves as the V2X casing 21, thus making full use of the space in the casing 34 of the vehicle rear view mirror, and not affecting the normal use of the reflective mirror 35, and no additional V2X casing 21 is required.
Of course, not limited to this, as shown in fig. 4, the V2X housing 21 may be a separate sealed housing 211 instead of the housing 34 of the rear view mirror, and the sealed housing 211 may be disposed on any side except the side where the mirror 35 is disposed, i.e. 5 positions ①, ②, ③, ④ and ⑤ shown in fig. 4, respectively on the upper side, the lower side, the left side, the right side and the front side of the housing 34 of the rear view mirror, as long as the sealed housing 211 is disposed on the rear side of the housing 34 of the rear view mirror to prevent the mirror 35 from being affected by the sealed housing 211, the bracket 22 fixes the sealed housing 211 and the housing 34 of the rear view mirror to the side of the vehicle head, for example, as shown in fig. 5 and fig. 6, two structures of ① and ③ positions shown in fig. 4 are listed respectively, other structures are similar to those shown in fig. 5 and fig. 6, and it is not listed one by one another, and it is seen that the sealed housing 211 may also carry the V2 device 40, because the position of the sealed housing 211 is similar to the antenna 732 of the antenna 34 of the vehicle rear view mirror, thereby preventing the antenna 732 from being extended signal from being over.
Specifically, the V2X casing 21 and the casing 34 of the vehicle rearview mirror (or both of the same structure, as shown in fig. 3) in the embodiment of the present invention may be made of a plastic material, such as ABS plastic (Acrylonitrile butadiene styrene plastic), TPE (Thermoplastic Elastomer), PA plastic (Polyamide), or the like, to avoid shielding the signals of the V2X device with a metal material.
It is noted that, as shown in fig. 2, 3, 5, and 6, the stent 22 is a hollow tubular stent; in this way, the connection line 42 is connected to the power supply system device 32 and the bus system device 33 in the vehicle through the inside of the hollow tubular bracket after being led out from the V2X device 40. It should be noted that, since the casing 34 of the rear view mirror needs to be fixed by a bracket originally, the hollow tubular bracket herein can directly fix the casing 34 of the rear view mirror and the casing 21 of V2X (or both are of the same structure, as shown in fig. 3) at the same time on the side of the head 31. The hollow tubular support can avoid the exposure of the connecting wire 42 and avoid the problem that the circuit is easy to damage.
Specifically, the connection line 42 includes a power connection line (as shown in fig. 2, 5, and 6, the connection line connected to the power supply system device 32 is a power connection line) and any one of the following buses (as shown in fig. 2, 5, and 6, the connection line connected to the bus system device 33 is a bus): a controller area network bus, an Ethernet bus and a vehicle-mounted Ethernet bus; the power supply connection line is connected to a power supply system device 32 inside the vehicle, and the controller area network bus, the ethernet bus, or the vehicle-mounted ethernet bus is connected to a bus system device 33 inside the vehicle. The power system device 32 may provide power to a V2X device, such as a 24V power supply. The Ethernet bus related by the invention refers to a common traditional Ethernet bus; and the vehicle ethernet bus is a physical network for connecting various electrical devices in the automobile. The onboard ethernet is designed to meet some special requirements in an onboard environment. For example: the requirements of the vehicle-mounted equipment on the electrical characteristics are met; the requirements of the vehicle-mounted equipment on the applications such as high bandwidth, low delay, audio and video synchronization and the like are met; the requirements of the vehicle-mounted system on network management are met, and the like. Therefore, it can be understood that the vehicle-mounted ethernet changes the electrical characteristics of the physical interface based on the common traditional ethernet protocol, and specifically customizes some new standards according to the requirements of the vehicle-mounted network.
Specifically, as shown in fig. 7, the V2X antenna 41 includes a V2X vertical antenna 411 and a V2X horizontal antenna 412. The V2X vertical antenna 411 protrudes outside the V2X housing 21 through a vertical antenna hole 212 vertically disposed at the upper end of the V2X housing 21; the V2X horizontal antenna 412 extends outside the V2X housing 21 through a horizontal antenna hole 213 provided in the horizontal direction of the V2X housing 21. The dual-antenna mode of the V2X vertical antenna 411 and the V2X horizontal antenna 412 is adopted here to satisfy the requirement that the vehicle realizes reliable signal transmission in a complex sheltering environment. The V2X vertical antenna 411 may be a high-gain omnidirectional antenna, the length is 20cm to 60cm, the feed length of the V2X vertical antenna 411 increases with the increase of the gain, the distance from the vertical antenna hole 212 to the V2X device 40 is generally not more than 20cm, and the V2X vertical antenna 411 is mainly used for ensuring long-distance transmission of signals. The V2X horizontal antenna 412 may be a low-gain omnidirectional antenna, and the length is usually short, the feed length of the V2X horizontal antenna 412 is the distance from the horizontal antenna hole 213 to the V2X device 40, and generally does not exceed 20cm, and the V2X horizontal antenna 412 is mainly used to ensure that there is more wireless signal energy coverage in a short distance. Therefore, signal coverage in the horizontal direction and the vertical direction of the lane plane can be ensured through a double-antenna mode, so that the polarity of the antenna can be ensured under the conditions of bumping and the like of a vehicle, and better communication quality and lower packet loss rate are ensured.
In addition, as shown in fig. 7, for example, the right side in fig. 7 is the position of the vehicle head, the horizontal antenna hole 213 is arranged on the side of the V2X casing 21 close to the vehicle, and the V2X horizontal antenna 412 protrudes from the horizontal antenna hole 213 and faces the side far away from the vehicle, and the protruding direction of the V2X horizontal antenna 412 is perpendicular to the vehicle traveling direction. The arrangement in this way takes into account that the side facing the vehicle may be in short space and that there may be a greater chance of the side facing the vehicle being obscured from signals by a subsequent metallic container.
In addition, in order to ensure the sealing performance, so that the Protection safety level of the V2X casing 21 and the casing 34 of the vehicle rearview mirror reaches the IP67(Ingress Protection Rating, solid Protection Rating 6, liquid Protection Rating 7), rubber pads or waterproof adhesive layers (not shown in the figure) are provided at the joints of the vertical antenna hole 212, the horizontal antenna hole 213, the V2X casing 21 and the bracket 22, and the boundary of the casing 34 of the vehicle rearview mirror and the reflective lens 35, so that rainwater or dust can be prevented from entering the inside of the casing.
In addition, as shown in fig. 8, an embodiment of the present invention further provides an automobile 50, which includes a towing vehicle head 51 and a carriage 52 connected to a rear end of the towing vehicle head 51. The carrying device 20 of the V2X equipment described above is arranged on either or both sides of the towing vehicle head 51 (here, the carrying device 20 of the V2X equipment is arranged on only one side in fig. 8 as an example), and both sides herein may refer to the left and right sides of the towing vehicle head 51, for example, referring to the positions of the vehicle rearview mirrors on both sides of the vehicle head. As shown in fig. 2, the V2X device 40 is disposed inside the V2X housing 21; the V2X device 40 is connected with a V2X antenna 41, the V2X antenna 41 extending outside the V2X housing 21; the V2X device 40 is connected to the power supply system device 32 and the bus system device 33 inside the vehicle through the connection line 42.
According to the carrying device of the V2X equipment and the automobile, the V2X shell is arranged on the side face of the automobile head, and the V2X equipment is placed in the shell, so that the V2X antenna cannot be too high when extending upwards. And, similar to the position of the rearview mirror of the vehicle, because the rearview mirror is on both sides of the vehicle head, its width is wider than the container in the rear of the vehicle, so can look over the field of vision behind the vehicle through the rearview mirror. In the embodiment of the invention, the bearing device of the V2X equipment is arranged on the side surface of the vehicle head, and the position of the bearing device is similar to that of a rearview mirror, so that the V2X equipment also protrudes out of the vehicle, and is convenient for communication with front and rear vehicles, particularly in an automatic driving fleet, the V2X equipment of each vehicle can be arranged on the same side of the vehicle head, and therefore, when the vehicle runs on a straight road, signals of the V2X antenna are basically not shielded by a metal container, and the signal strength is ensured. In addition, compared with the V2X device arranged in the locomotive in the prior art, the bearing device of the V2X device is arranged on the side face of the locomotive, and the length of a feeder line between the V2X device and the V2X antenna is shorter, so that the attenuation of signal strength on the feeder line is greatly reduced, and meanwhile, the expensive feeder line cost is reduced. The invention can ensure the communication signal strength of the V2X equipment under the condition that the V2X antenna is not ultrahigh, and avoid the adverse effect on the communication of the V2X equipment caused by the signal being shielded by a metal hanging box at the rear part of the vehicle.
