Description

Technical Field

[0001] The present disclosure generally relates to information transfer from a Telecommunication Control Unit (TCU) to a compensator by time-keying a transmit / receive (TX / RX) switch signal. Background Art

[0002] As vehicles become more data-driven, the need to communicate with the outside world becomes increasingly important. Individuals in vehicles often rely on personal mobile devices to stream music, communicate with others, and navigate. The vehicle itself may also be in contact with external systems. This communication allows for over-the-air updates from a central server, information about external conditions related to the vehicle through vehicle-to-everything (V2X) communications, and navigation information. If the vehicle is intended to have autonomous driving features, having the ability to provide sensory data to a central server can allow for the receipt of improved driving algorithms. Therefore, there are many reasons to provide data to and from a vehicle.

[0003] However, as can be appreciated, the design of the vehicle is not well suited for transmitting RF signals because the extensive use of metal acts to significantly attenuate the signal. To address the attenuation, a compensator or signal amplifier device (e.g., a Molex compensator) may be provided. TM (Molex Compenser TM ) signal amplifier device) to eliminate signal loss within the vehicle. Summary of the invention

[0004] This section provides a general summary of the disclosure, and is not a comprehensive disclosure of its full scope or all of its features.

[0005] Disclosed are exemplary embodiments of methods, systems, and devices configured to time-key a transmit / receive (TX / RX) switch signal (e.g., a pilot tone signal, pulses on a phantom power supply, other modulation on a coaxial connecting cable, etc.) sent from a first device (e.g., a telecommunications control unit (TCU), etc.) to a second device (e.g., a compensator, etc.).

[0006] Further areas of applicability will become apparent from the description provided herein.The description and specific examples in this summary are intended for purposes of illustration only and are not intended to limit the scope of the present disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The following detailed description describes exemplary embodiments, and the disclosed features are not intended to be limited to the explicitly disclosed combinations. Therefore, unless otherwise stated, the features disclosed herein may be combined to form additional combinations that are not otherwise shown for the sake of brevity.

[0013] Time keying is a technique for controlling the timing of signals used to control or encode information. Time keying a transmit / receive switch signal is a technique for managing the timing of signals used to transmit and receive data.

[0014] In various types of communication devices, such as radios or transceivers, a single antenna is often used for both transmitting and receiving signals. However, transmission and reception cannot occur simultaneously on the same antenna without interference.

[0015] Time-keyed switching is used to switch the system between transmit mode and receive mode alternately. Timing signals (often called switch signals) control when the system sends data and when the system receives data.

[0016] For systems that share a single channel or resource between multiple operations (such as in a shared antenna system for both transmitting and receiving), time keying controls the exact moment when the switch between the two operating modes occurs, ensuring that each operation occurs at its designated time without overlap.

[0017] For example, in Time Division Multiplexing (TDM) or Time Division Duplexing (TDD), time keying is used to switch between different operations (e.g., transmission and reception) based on precise timing. For example, in a TDD system, the transmitter and receiver share the same frequency channel but operate at different times, where time keying controls when the switch between transmission and reception occurs.

[0018] For time keying modulation, time keying is used to encode data into a signal by varying the timing of certain signal events. For example, in a simple form of pulse modulation, the presence or absence of a pulse in a given time slot can represent different data bits.

[0019] In some aspects, a compensator (also referred to as a signal amplifier device) eliminates signal loss within a vehicle. A compensator (e.g., a dedicated short range communication (DSCR) compensator, a V2X compensator, a cellular to V2X (c-V2X) compensator, etc.) is used to compensate for cable losses between a telematics control unit (TCU) and an antenna. Although some examples are described with reference to using a compensator in a vehicle, the same principles can be used in any situation where cable losses are an issue in a system with a transmit / receive switch signal.

[0020] Figure 1 A compensator 104 (eg, Molex Compenser 104) is shown connected to a TCU 108 within a vehicle 112. TM signal amplifier device, etc.). The compensator 104 is a bidirectional signal amplifier device. Although some examples are described with reference to Molex devices, the same principles can be used for any other type of TCU.

[0021] The transmit / receive compensator 104 is a device or circuit used to improve the performance of both the transmission and reception of signals. The compensator helps to correct or adjust for various defects and distortions in the signal that may occur during the transmission and reception process.

[0022] During transmission, the compensator 104 can adjust the power level of the transmitted signal to ensure that it is strong enough to reach the receiver without being too strong, which may cause interference or signal distortion. The compensator can also linearize the power amplifier to reduce distortion in the transmitted signal. In addition, the compensator can ensure that the impedance of the transmission line matches the output impedance of the transmitter to minimize reflections and power losses.

[0023] During reception, compensator 104 adjusts the gain of the received signal to ensure that the signal is neither too weak nor too strong. In addition, compensator 104 filters out noise and unwanted signals, thereby improving the signal-to-noise ratio (SNR) and making the received signal clearer. In addition, compensator 104 can correct for phase and frequency errors introduced during transmission, thereby helping to align the received signal with the original transmitted signal.

[0024] In the example shown, the compensator 104 is located on or adjacent to the windshield of the vehicle 112 (e.g., behind a rearview mirror, etc.) to provide communication with the vehicle ahead and other devices nearby in the area where the vehicle is traveling or parked. The compensator 104 also interacts with an antenna 102 (e.g., a roof-mounted antenna, etc.). A cable 110 connects the compensator 104 to the TCU 108, and a cable 106 connects the TCU 108 to the antenna 102.

[0025] The transmitted data may be used for safety, navigation, and autonomous driving purposes. Although the compensator 104 and TCU 108 are shown along the windshield and under the seat of the vehicle, respectively, the compensator 104 and TCU 108 may be located elsewhere. For example, the TCU 108 may be located on the roof of the vehicle or under the vehicle dashboard instead of under the vehicle seat, and the compensator 104 may also be located at other locations, such as in the roof antenna, in the front grille, or near the rear of the vehicle, but is not limited thereto.

[0026] The system including the TCU 108, cables 106, 110 and compensator 104 is preferably configured to comply with the standard. In addition to other parameters, the output power of the compensator 104 is also preferably controlled in the compensator 104 within the limits defined by the standard. Therefore, the gain of the compensator 104 is preferably adjusted so that the cable loss, temperature and frequency response of the system are compensated. To achieve this, a feedforward loop can be used, in which the TCU 108 sends the requested output power to the compensator 104, and the compensator 104 is configured (for example, but not limited to, configured with local closed-loop feedback measured after the compensator) to ensure that the resulting output matches the requested power level. Information including the requested output power from the TCU 108 to the compensator 104 can be sent in various ways, such as by implementing a serial protocol, a parallel protocol, etc.

[0027] Disclosed herein are exemplary embodiments of methods, systems, and devices (e.g., circuits, compensators, signal amplifier devices, etc.) configured to be operable to exchange information between a TCU 108 and a compensator 104 (e.g., a V2X compensator, a c-V2X compensator, etc.) by time-keying a transmit / receive switch signal. Advantageously, according to some examples, the exemplary embodiments disclosed herein provide a cost-effective alternative to transmitting information from the TCU 108 to the compensator 104 by time-keying the TX / RX switch signal (which can be achieved by using a non-complex timer in a control unit of the compensator 104).

[0028] A switching signal is a type of electrical signal used to control the operation of an electronic circuit, device, or system by turning them on or off, or by switching them between different states. The signal is typically digital or binary, meaning that it can have one of two possible values: high (1) or low (0), corresponding to the "on" or "off" state, respectively. A switching signal is typically represented by a voltage level that is either high (e.g., +5V, +3.3V) or low (e.g., 0V, ground). A switching signal is used to control the operation of another circuit or device. For example, a switching signal can turn a transistor on or off, enable or disable a function in a microcontroller, or switch between different operating modes in a larger system. A switching signal can occur at a specific time or frequency. For example, in a pulse width modulation (PWM) system, the switching signal determines the duty cycle, which controls the amount of power delivered to the load. Switching signals are used in circuits such as power supplies, amplifiers, digital logic circuits, and communication systems, and can be used to switch power to different components, modulate signals, or control the flow of data in a digital system.

[0029] Figure 2 is a block diagram of a system 200 including a compensator 104 having a time-keyed feed-forward loop configured to time-key a transmit / receive switch signal according to an exemplary embodiment.

[0030] The compensator 104 includes several components for managing RF signals. The compensator 104 is coupled to the TCU 108 via a cable 110. In the exemplary embodiment, the compensator 104 includes a time-keyed feed-forward loop that is configured to be operable to time-key the transmit / receive switch signal. In some examples, the compensator 104 may include a V2X compensator, a c-V2X compensator, etc., but other examples may use other types of compensators.

[0031] The compensator 104 is configured to be operable to use a pilot signal (broadly referred to as a transmit / receive switch signal) from the TCU 108 that indicates that the transmit (TX) mode is active. The compensator 104 includes a receive / transmit (RX / TX) detector 216 and a control unit 220 coupled to the receive / transmit detector 216. In other exemplary embodiments, the compensator 104 may be configured to be operable to use other transmit / receive switch signals, such as pulses on phantom power, other modulations on the coaxial connection cable 110, etc.

[0032] The input signal 228 is processed by the signal separator 280 and the attenuator 224 to condition the signal for further processing. The receive / transmit detector 216 is coupled to the signal separator 280 to receive the RF signal and determine the mode of operation (transmit or receive).

[0033] The compensator 104 further includes a first switch 232 coupled to the attenuator 224, a low noise amplifier 236 (LNA), a power amplifier 240 (PA), and a second switch 244. The second switch 244 is coupled to the first switch 232, the low noise amplifier 236, the power amplifier 240, and a band pass filter 248 (BPF).

[0034] The bandpass filter 248 is also coupled to the output 252 of the compensator 104. In some examples, the signal on the input signal 228 includes three signal domains: an operating signal (e.g., at about 5.9 GHz), a pilot signal (e.g., 125 MHz), and a DC phantom power supply. The frequencies of 5.9 GHz and 125 MHz are examples only, as the exemplary embodiments disclosed herein are not limited to any particular frequencies.

[0035] A pilot signal is a continuous low-level signal of a specific frequency used as a reference or control signal. The pilot signal itself does not usually carry any information, but plays a role in maintaining the quality and reliability of the transmitted or processed signal. A DC phantom power signal (also called phantom power) delivers a DC voltage over the same wire that carries other signals.

[0036] The signal separator 280 uses passive filters to separate the three signals of the three domains. The separated pilot signal is rectified in the receive / transmit detector 216 and then analyzed in the control unit 220. For practical reasons, it is helpful if the operating frequency band and the pilot signal frequency have a significant difference to facilitate signal separation in the second device.

[0037] In the transmit path, the conditioned RF signal is amplified by a power amplifier 240 before being routed through a second switch 244 to a bandpass filter 248 , which filters the amplified signal for transmission through an antenna coupled to an output 252 .

[0038] In the receive path, the signal received by the antenna is filtered by the BPF 248 and routed to the low noise amplifier 236 for amplification through the second switch 244. The amplified signal is then directed back to the attenuator 224 on its way to the signal separator 280 and output to the cable 110 and TCU 108.

[0039] Control unit 220 within compensator 104 includes measurement unit 256, timer 268, reconstructor 264, comparator 272, and low pass filter 276. Control unit 220 is coupled to receive / transmit detector 216 and diode detector 260, which is an electronic circuit that uses a diode to detect or demodulate a signal.

[0040] The control unit 220 is configured to keep the transmit-on (TX-on) signal active during the pilot signal time gap and measure its length. Figure 3 Describes more details about the pilot gap. The TX-on signal is used to indicate that the transmitter is active and is sending data. TX-on is only active when sending data and is turned off when not sending data to save power and reduce interference.

[0041] The measuring unit 256 is used to measure the current of the output power from the TCU 108 to the compensator 104. The reconstructor 264 is used to reconstruct the TX-on signal, and the timer 268 measures the pilot gap. The reconstructed TX-on signal from the reconstructor 264 is sent to the node 270 to set the first switch 232 and the second switch 244 in the transmit / receive path.

[0042] The digital value of the gap length representing the target power is compared with the actual measured RF power provided by the measurement unit 256 in the comparator 272. The comparator 272 is a circuit that subtracts the target power from the actual power to achieve the regulation standard of the control loop. The output signal from the comparator 272 passes through the low pass filter 276 and closes the power control loop by adjusting the output of the attenuator 224.

[0043] The control unit 220 includes a feedback loop having a function h(t) that compares the measured power output to a target power (P-target) to dynamically control the time response of the control loop.

[0044] Figure 3 Internal timing of a compensator including a time-keyed feed-forward loop configured to be operable to time-key a transmit / receive switch signal is shown according to an exemplary embodiment. Figure 3The example shown in includes compensator internal timing, where the transmit / receive control signal 302 (eg, a 125 MHz pilot signal from a TCU) is not turned off but remains on during the entire transmit cycle 312 (TX cycle).

[0045] exist Figure 3 In the method shown in , the compensator is configured to receive a pilot signal 304 (eg, 125 MHz) from the TCU as an indicator of whether the transmit (TX) mode is active or inactive. Figure 3 As shown in trace 1 in FIG. 3 , the pilot signal 304 is turned off for a certain period of time after the TX mode is activated. This period of time is called a pilot gap 314.

[0046] The duration of the pilot gap 314 (during which the pilot signal 304 is turned off) is proportional to the requested output power of the compensator. In some examples, the maximum duration of the pilot gap 314 is less than the duration of the shortest possible (possible, or available) transmission frame. In addition, the duration of the pilot gap 314 is measured by the timer 268 of the control unit 220 in the compensator 104.

[0047] The pilot signal 304 is demodulated via the receive / transmit detector 216 of the compensator 104 and the reconstructor 264 in the control unit 220. Signal 306 (Trace 2) is the signal resulting from the demodulated pilot signal 304. Signal 306 is "off" (low voltage) during the pilot gap 314. However, the duration of the off period on signal 306 may vary and may be adjusted via a feed-forward loop so the off period of signal 306 may end before or after the end of pilot gap 314.

[0048] In order to improve the robustness of the evaluation of the duration of the pilot gap 314, the pilot gap 314 is optionally divided into two parts of equal duration (sub-gap 315 and sub-gap 316) for error detection. The sub-gap 315 and 316 are separated by the period when the pilot signal 304 is on. When the difference between the measured durations of the sub-gap 315 and the sub-gap 316 is within a predetermined threshold limit, the evaluation result is considered valid.

[0049] Error detection circuits can be used in several ways, depending on the type and application of the system. Error detection can be used for several purposes:

[0050] - Error correction, e.g., automatic correction if the system includes error correction capabilities (e.g., in digital communication systems with error correction codes). For example, if a parity check fails, the system can use additional data bits to correct the error.

[0051] -Request retransmission, request retransmission of data from the sender.

[0052] - Error flagging, triggering an indicator (such as a light emitting diode (LED) or an alarm) to notify the user that an error has been detected or logging the error in the system.

[0053] - System recovery, resetting the system or components that may have caused the error, or for fallback mode, where the output can be initiated to switch to a fallback or safe mode.

[0054] -Fault tolerance in systems with redundant components, or error masking that masks errors and continues to operate, possibly with degraded performance, until the problem can be resolved.

[0055] - User feedback, for example, an error may trigger a display or screen message to inform the user that a specific error has been detected, or an audible alarm.

[0056] In the example shown, the durations of sub-gap 315 and sub-gap 316 are compared during detection. In some examples, the lengths of the two signal gaps are measured in real time by a timer internal to the gating control unit.

[0057] To avoid the transmit mode (TX-on mode) from being deactivated or turned off during the pilot gap 314, an internal hold signal 308 (Trace 3) is used to take over the TX activation during the pilot gap 314. The internal hold signal 308 has a minimum duration equal to the minimum TX burst duration.

[0058] In some examples, the duration of the on period of the internal hold signal 308 is configured to keep TX on during the feedforward pilot gap 314. Thus, despite the presence of the pilot gap 314, the TX-on mode is maintained throughout the pilot gap 314.

[0059] The combination (eg, addition or using a logical OR function) of signal 306 and internal hold signal 308 produces internal TX-on signal 310 (Trace 4), which is the minimum length of internal TX-on signal covering TX-on.

[0060] Thus, the internal TX-on signal 310 "masks" the fact that the pilot signal 304 includes a gap, so the transmission continues for at least the minimum required length.

[0061] Signal 306 is used to control attenuator 224; that is, the value of signal 306 is used to control the power output of attenuator 224. This means that pilot gap 314 and the feed-forward loop are used to control the power of the attenuator. The TCU can control pilot gap 314 to direct the compensator to adjust the power level of the signal.

[0062] Therefore, exemplary embodiments of methods, systems, and devices configured to time-key a transmit / receive switch signal (e.g., a pilot signal 304, pulses on a phantom power supply, other modulations on a coaxial connecting cable, etc.) sent from a first device (e.g., a TCU, etc.) to a second device (e.g., a compensator, etc.) are disclosed.

[0063] Figure 4 4 is a flow chart of a method 400 for time-keying a transmit / receive switch signal according to some embodiments. Although various operations in the flow chart are presented and described sequentially, a person of ordinary skill will appreciate that some or all of the operations may be performed in a different order, combined or omitted, or performed in parallel.

[0064] Operation 402 is for receiving, by a compensator, an input signal including a pilot signal and an operating signal.

[0065] From operation 402, the method 400 proceeds to operation 404 for detecting a transmission period based on a pilot signal.

[0066] From operation 404, the method 400 proceeds to operation 406 for measuring pilot gaps during a transmission period in which the pilot signal is turned off.

[0067] From operation 406, the method 400 proceeds to operation 408 for generating an internal transmit on signal based on the pilot signal. The internal transmit on signal is active during the pilot gap to keep the compensator in the transmit mode during the pilot gap.

[0068] From operation 408, the method 400 proceeds to operation 410 for adjusting the output power level of the compensator based on the pilot gap.

[0069] In view of the above disclosure, various examples are described below. It should be noted that one or more features of the examples taken alone or in combination should be considered within the disclosure of the present application.
