Fig. 1 is a block diagram illustrating an in-vehicle antenna apparatus according to an exemplary embodiment, and as shown in fig. 1, the in-vehicle antenna apparatus 100 includes a first signal conversion module 101 and an antenna module 102.
The first signal conversion module 101 is configured to receive a first digital signal sent by the vehicle-mounted remote communication terminal 200, convert the first digital signal into a first radio frequency signal, and send the first radio frequency signal to an antenna.

The antenna module 102 is a device for transmitting/receiving radio frequency signals to/from the outside. For example, the antenna module 102 may be a bluetooth antenna, a WIFI antenna, a 4G antenna, a 5G antenna. The antenna module 102 may include a variety of antennas. For example, the antenna module 102 may include two or more antennas of a bluetooth antenna, a WIFI antenna, a 4G antenna, and a 5G antenna.
The first signal conversion module 101 is a circuit for converting a radio frequency signal into a digital signal and/or converting a digital signal into a radio frequency signal. Fig. 2 is a block diagram of an in-vehicle antenna apparatus according to another exemplary embodiment. As shown in fig. 2, the first signal conversion module 101 may include a first switch, a first filter (e.g., a Surface Acoustic Wave (SAW) filter), a duplexer, a Power Amplifier (PA), a second switch, a second filter (e.g., SAW), a third filter (e.g., SAW), a Low Noise Amplifier (LNA), and a signal transceiver. The antenna module 102 may include a Long Term Evolution (LTE) host antenna, a Global Navigation Satellite System (GNSS) receiving antenna, and a diversity receiving antenna. In such an embodiment, functions and connection modes of the components (the first switch, the first filter, the duplexer, the power amplifier, the second switch, the second filter, the third filter, the low noise amplifier, the signal transceiver, the LTE host antenna, the GNSS receiving antenna, and the diversity receiving antenna) are well known to those skilled in the art and will not be described herein too much.
The first digital signal refers to a digital signal transmitted from the in-vehicle telecommunication terminal 200 to the first signal conversion module 101. The first radio frequency signal is a radio frequency signal generated after the first digital signal is converted by the first signal conversion module 101. The first signal conversion module may be a circuit that converts a radio frequency signal into a digital signal and converts the digital signal into a radio frequency signal. The second rf signal refers to an rf signal received from the outside by the antenna module 102. The second digital signal is a digital signal obtained by converting the second radio frequency signal through the first signal conversion module 101.
Specifically, the vehicle-mounted antenna device 100 includes a first signal conversion module 101 and an antenna module 102. The antenna module 102 acquires a second radio frequency signal from the outside and transmits the second radio frequency signal to the first signal conversion module 101; the first signal conversion module 101 converts the second radio frequency signal into a second digital signal. The first signal conversion module 101 receives a first digital signal transmitted by the vehicle-mounted remote communication terminal 200, and converts the first digital signal into a first radio frequency signal. After receiving the first rf signal transmitted by the first signal conversion module 101, the antenna module 102 sends the first rf signal to the outside. In other words, the rf signals (the first rf signal and the second rf signal) and the digital signals (the first digital signal and the second digital signal) can be mutually converted inside the vehicle-mounted antenna device 100. When signal transmission is performed between the in-vehicle antenna device 100 and the in-vehicle remote communication terminal 200, the signal may be transmitted in the form of a digital signal (first digital signal, second digital signal).
Through the technical scheme, in the vehicle-mounted antenna device, the antenna module and the first signal conversion module are included, mutual conversion between radio-frequency signals and digital signals can be completed inside the vehicle-mounted antenna device, and therefore when signal transmission is performed between the vehicle-mounted antenna device and the vehicle-mounted remote communication terminal, the signals can be transmitted in a digital signal mode, and the problem of large line loss caused by long-distance transmission of the radio-frequency signals is solved. In addition, because the signal transmitted between the vehicle-mounted antenna device and the vehicle-mounted remote communication terminal is a digital signal, the anti-interference capability in the signal transmission process can be improved, and the stability and the reliability of a vehicle-mounted communication system are improved.
In still another embodiment, the vehicle-mounted antenna apparatus 100 further includes a first digital connector through which the first signal conversion module 101 is connected with the vehicle-mounted telecommunication terminal 200.

For example, the first digital connector may be an RJ11 connector, and for example, the first digital connector may be an RJ45 connector.
In this embodiment, the vehicle-mounted antenna device includes the first digital connector, so that when signal transmission is performed between the vehicle-mounted antenna device and the vehicle-mounted remote communication terminal, a signal transmission channel can be established through the first digital connector, so that signals are transmitted between the vehicle-mounted antenna device and the vehicle-mounted remote communication terminal in a digital signal form, and the anti-interference capability in the signal transmission process is improved.
In yet another embodiment, the first digital connector comprises a twisted pair interface or a fiber interface.
For example, the twisted pair interface may be an interface of an RJ11 connector or an interface of an RJ45 connector. The optical fiber interface can be an SC type optical fiber interface or an FC type optical fiber interface. That is, the interface type (twisted pair interface or fiber interface) of the first digital connector may be selected according to design requirements. In one embodiment, the vehicle-mounted antenna device can perform digital signal transmission with the vehicle-mounted remote communication terminal through the optical fiber, so that the transmission rate of the digital signal transmission between the vehicle-mounted antenna device and the vehicle-mounted remote communication terminal is faster (compared with the transmission of the digital signal through the twisted pair).
In this embodiment, the first digital connector may include an optical fiber interface, so that when signal transmission is performed between the vehicle-mounted antenna device and the vehicle-mounted remote communication terminal, the signal transmission rate is faster, and the communication performance between the vehicle-mounted antenna device and the vehicle-mounted remote communication terminal is improved.
In yet another embodiment, the vehicle-mounted antenna apparatus 100 further includes a first power module for supplying power to the antenna module 102 and the first signal conversion module 101.
The first power supply module may be a power supply integrated in the vehicle-mounted antenna apparatus 100 for supplying power to the antenna module and the first signal conversion module. In this embodiment, the vehicle-mounted antenna apparatus is equipped with the power supply module itself, and thus, the possibility of crosstalk with the power supply of the vehicle-mounted antenna apparatus and other power supplies is reduced, and the stability of the vehicle-mounted communication system is improved.

That is to say, when signal transmission is carried out between the vehicle-mounted remote communication terminal and the vehicle-mounted antenna device, signals can be transmitted in a digital signal mode, and the problem of large line loss caused by long-distance transmission of radio frequency signals is solved. Moreover, the anti-interference capability in the signal transmission process can be improved, and the stability and the reliability of the vehicle-mounted wireless communication system can be improved.
In still another embodiment, the in-vehicle remote communication terminal 200 further includes a second digital connector through which the second signal conversion module 202 is connected with the in-vehicle antenna device 100.

For example, the second digital connector may be an RJ11 connector; also for example, the second digital connector may be an RJ45 connector. In one embodiment, the second digital connector of the in-vehicle remote communication terminal 200 and the first digital connector of the in-vehicle antenna device may be connected by a twisted pair wire, so that the in-vehicle remote communication terminal 200 and the in-vehicle antenna device 100 are electrically connected.
In this embodiment, the vehicle-mounted remote communication terminal includes the second digital connector, so that when signal transmission is performed between the vehicle-mounted antenna device and the vehicle-mounted remote communication terminal, a signal transmission channel can be established through the second digital connector, so that signals are transmitted between the vehicle-mounted remote communication terminal and the vehicle-mounted antenna device in a digital signal form, and the anti-interference capability in the signal transmission process is improved.
In yet another embodiment, the second digital connector comprises a twisted pair interface or an optical fiber interface.
The interface type (twisted pair interface or fiber interface) of the second digital connector may be selected according to design requirements. In one embodiment, the vehicle-mounted remote communication terminal can perform digital signal transmission with the vehicle-mounted antenna device through the optical fiber, so that the transmission rate of the digital signal transmission between the vehicle-mounted remote communication terminal and the vehicle-mounted antenna device is faster (compared with the transmission of the digital signal through the twisted pair).

Some or all of the functionality of the vehicle 600 is controlled by the computing platform 650. Computing platform 650 can include at least one processor 651, which processor 651 can execute instructions 653 stored in a non-transitory computer-readable medium, such as memory 652. In some embodiments, computing platform 650 may also be a plurality of computing devices that control individual components or subsystems of vehicle 600 in a distributed manner.
The processor 651 may be any conventional processor, such as a commercially available CPU. Alternatively, processor 651 may also comprise a processor such as a Graphics Processing Unit (GPU), Field Programmable Gate Array (FPGA), System On Chip (SOC), Application Specific Integrated Circuit (ASIC), or a combination thereof. Although fig. 4 functionally illustrates a processor, memory, and other elements of a computer in the same block, those skilled in the art will appreciate that the processor, computer, or memory may actually comprise multiple processors, computers, or memories that may or may not be stored within the same physical housing. For example, the memory may be a hard drive or other storage medium located in a different enclosure than the computer. Thus, references to a processor or computer are to be understood as including references to a collection of processors or computers or memories which may or may not operate in parallel. Rather than using a single processor to perform the steps described herein, some components, such as the steering component and the retarding component, may each have their own processor that performs only computations related to the component-specific functions.
In various aspects described herein, the processor 651 can be located remotely from the vehicle and in wireless communication with the vehicle. In other aspects, some of the processes described herein are executed on a processor disposed within the vehicle and others are executed by a remote processor, including taking the steps necessary to perform a single maneuver.
In some embodiments, the memory 652 may contain instructions 653 (e.g., program logic), which instructions 653 may be executed by the processor 651 to perform various functions of the vehicle 600. The memory 652 may also contain additional instructions, including instructions to send data to, receive data from, interact with, and/or control one or more of the infotainment system 610, the perception system 620, the decision control system 630, the drive system 640.
In addition to instructions 653, memory 652 may also store data such as road maps, route information, the location, direction, speed, and other such vehicle data of the vehicle, as well as other information. Such information may be used by the vehicle 600 and the computing platform 650 during operation of the vehicle 600 in autonomous, semi-autonomous, and/or manual modes.
Computing platform 650 may control functions of vehicle 600 based on inputs received from various subsystems (e.g., drive system 640, perception system 620, and decision control system 630). For example, computing platform 650 may utilize input from decision control system 630 in order to control steering system 633 to avoid obstacles detected by perception system 620. In some embodiments, the computing platform 650 is operable to provide control over many aspects of the vehicle 600 and its subsystems.
Optionally, one or more of these components described above may be mounted or associated separately from the vehicle 600. For example, the memory 652 may exist partially or completely separate from the vehicle 600. The above components may be communicatively coupled together in a wired and/or wireless manner.
Optionally, the above components are only an example, in an actual application, components in the above modules may be added or deleted according to an actual need, and fig. 4 should not be construed as limiting the embodiment of the present disclosure.
An autonomous automobile traveling on a roadway, such as vehicle 600 above, may identify objects within its surrounding environment to determine an adjustment to the current speed. The object may be another vehicle, a traffic control device, or another type of object. In some examples, each identified object may be considered independently, and based on the respective characteristics of the object, such as its current speed, acceleration, separation from the vehicle, etc., may be used to determine the speed at which the autonomous vehicle is to be adjusted.
Optionally, the vehicle 600 or a sensory and computing device associated with the vehicle 600 (e.g., computing system 631, computing platform 650) may predict behavior of the identified object based on characteristics of the identified object and the state of the surrounding environment (e.g., traffic, rain, ice on the road, etc.). Optionally, each identified object depends on the behavior of each other, so it is also possible to predict the behavior of a single identified object taking all identified objects together into account. The vehicle 600 is able to adjust its speed based on the predicted behavior of the identified object. In other words, the autonomous vehicle is able to determine what steady state the vehicle will need to adjust to (e.g., accelerate, decelerate, or stop) based on the predicted behavior of the object. In this process, other factors may also be considered to determine the speed of the vehicle 600, such as the lateral position of the vehicle 600 in the road being traveled, the curvature of the road, the proximity of static and dynamic objects, and so forth.
In addition to providing instructions to adjust the speed of the autonomous vehicle, the computing device may provide instructions to modify the steering angle of the vehicle 600 to cause the autonomous vehicle to follow a given trajectory and/or to maintain a safe lateral and longitudinal distance from objects in the vicinity of the autonomous vehicle (e.g., vehicles in adjacent lanes on the road).
The vehicle 600 may be any type of vehicle, such as a car, a truck, a motorcycle, a bus, a boat, an airplane, a helicopter, a recreational vehicle, a train, etc., and the disclosed embodiment is not particularly limited.
Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the disclosure. This application is intended to cover any variations, uses, or adaptations of the disclosure following, in general, the principles of the disclosure and including such departures from the present disclosure as come within known or customary practice within the art to which the disclosure pertains.
