[0019] Problem Overview

[0020] Figure 1 is a block diagram of a conventional vehicle wireless communication unit (WCU) 100 according to an embodiment. The WCU 100 includes a communication processor circuitry 101, a wireless transceiver 102, a main power supply 103, and a backup power supply 104 (hereinafter also referred to as "WCU components"). The wireless transceiver 102 is coupled to an antenna 105 via a wiring harness 106. Some examples of the wiring harness 106 include, but are not limited to, unshielded twisted pair, shielded twisted pair, coaxial cable, unshielded parallel pair, shielded parallel, and optical media or any combination thereof.

[0021] WCU 100 provides wireless services (e.g., internet connectivity, vehicle-to-vehicle (V2V) communication) using remote devices and resources external to the vehicle. WCU 100 can be included in any type of vehicle, including autonomous vehicles. As used herein, "vehicle" includes devices for transferring goods or people. Examples include cars, buses, trains, airplanes, drones, trucks, boats, ships, submersibles, spacecraft, mobile robots, etc. Driverless cars are an example of AVs. As used herein, an autonomous vehicle (AV) is a vehicle with autonomous capabilities. As used herein, the term "autonomy" refers to the functions, features, or facilities that enable a vehicle to operate partially or fully without real-time human intervention, including but not limited to fully autonomous vehicles, highly autonomous vehicles, and conditionally autonomous vehicles.

[0022] The communication processor unit 101 is coupled to the communication interface 107 for receiving data from a vehicle data network. For example, the communication interface 107 may include circuitry for coupling to one or more vehicle bus systems, including but not limited to: Controller Area Network (CAN) bus, Local Area Network (LIN), FlexRay, and Ethernet. The data may include, but is not limited to, the status of various vehicle components, sensor data, and perceptions of the vehicle's surrounding environment captured by the vehicle's sensors (e.g., object detection data). The vehicle may include one or more sensors for detecting passenger presence, airbag activation, tire pressure, vehicle location, road conditions, etc., and outputting sensor data to the data network. The communication processor circuitry 101 analyzes the data and establishes a wireless communication session with a responder outside the vehicle to receive the data. For example, if the data indicates that the airbags have been activated and multiple passengers are present inside the vehicle, the communication processor circuitry 101 initiates an emergency call to the eCall emergency alarm system.

[0023] Wireless transceiver 102 includes circuitry (e.g., a wireless receiver and a transmitter) and software / firmware (e.g., a TCP / IP stack) for establishing and maintaining a bidirectional communication channel with one or more responders. For example, wireless transceiver 102 can establish a real-time voice / video channel with an emergency call center, allowing passengers within the vehicle to communicate with personnel at the emergency call center.

[0024] Main power supply 103 supplies power to WCU 100 to ensure the normal operation of the WCU components. In this example, main power supply 103 draws power from the vehicle's power network using power interface 108, monitors input / output voltages and / or the current levels of the WCU components, and adjusts the power delivery to each WCU component. In an emergency, main power supply 103 may cease operation due to loss of connection to the vehicle's power network. Furthermore, it may be unsafe for main power supply 103 to continue drawing power from the vehicle's power network due to the risk of damage to the vehicle. In these situations, backup power supply 104 allows WCU 100 to continue operating after main power supply 103 is disabled. For example, a battery interruption system (e.g., a power switch, a fuse) in WCU 100 may be configured to disconnect main power supply 103 from power interface 112 and use backup power supply 104 to supply power to the WCU components in an emergency.

[0025] In one embodiment, the WCU 100 is installed in a collision safety area within the vehicle to reduce the likelihood of component damage in the event of an accident. For example, the WCU 100 may be installed in a passenger area, such as the space between the front and rear seats. On the other hand, the antenna 105 is typically mounted above the top of the vehicle to maximize signal strength. Thus, a wiring harness 106 is used to couple the antenna 105 to the WCU 100 at the wireless transceiver 102. However, this configuration incurs additional cost due to the requirements of the wiring harness 106, and also introduces signal interference due to the distance between the antenna 105 and the wireless transceiver 102. In another embodiment, the WCU 100 is mounted adjacent to the antenna 105 to reduce the length of the wiring harness 106. For example, the WCU 100 may be installed below the top of the vehicle, adjacent to the antenna 105. However, in this configuration, the WCU 102 is susceptible to temperature damage because the top of the vehicle can become a heated environment.

[0026] Partitioned wireless communication system

[0027] Figure 2This is a block diagram of a partitioned vehicle wireless communication system (PWCS) 200 with redundant data links 209 and redundant power lines 210 according to an embodiment. As used herein, the term "partitioned" refers to being divided into several parts. For example, a single hardware communication unit may be "partitioned" into two physically independent hardware units coupled together by data links and power lines and placed at different locations within the vehicle.

[0028] In the illustrated embodiment, the PWCS 200 includes a communication gateway unit (CGU) 201 coupled to a remote wireless transceiver unit (RWTU) 202 via a redundant data link 209 and a redundant power line 210. The CGU 201 and RWTU 202 are placed at different locations within the vehicle. For example, the CGU 201 may be placed in the lower region of the vehicle, and the RWTU 202 may be placed below the top of the vehicle, adjacent to antennas 215a-215c. In this embodiment, each of the CGU 201 and RWTU 202 includes a housing covering one or more integrated circuit chips or chipsets for wireless communication data interfaces and power. Any number or type of transmitters, receivers, or transceivers, and any number or type of antennas 215a-215c (e.g., omnidirectional, directional, MIMO, antenna arrays) may be included or coupled to the RWTU 202. One or more of antennas 215a-215c may be configurable, allowing the antenna bundle to be manually or automatically pointed in any desired direction. Multiple cellular antennas can be used for network connectivity, Global Navigation Satellite System (GNSS) antennas for navigation to emergency call systems, and other location-based applications for vehicle-to-vehicle / infrastructure applications, satellite radio, radar, AM / FM radio, WiFi hotspot connectivity, and Dedicated Short Range Communications (DSRC).

[0029] In the example shown, CGU 201 includes communication processor circuitry 203 (e.g., a central processing unit, controller, ASIC), a data interface 204a, a main power supply 206, and a backup power supply 205. Data interface 204a includes circuitry (e.g., amplifiers, buffers, processors) for coupling CGU 201 to redundant data link 209. CGU 201 is further coupled to redundant communication interface 207 for interfacing with a dual-loop data network (e.g., a dual-loop self-healing network) in the vehicle. CGU 202 is further coupled to redundant power interface 208 for interfacing with a dual-loop power network in the vehicle.

[0030] CGU 201 is responsible for analyzing vehicle data and routing data and power to RWTU 202. In this embodiment, communication processor circuitry 203 receives vehicle data from redundant communication interface 207 coupled to the vehicle data network. Main power supply 206 draws power from redundant power interface 208 coupled to the vehicle power network. In the event of data and / or power loss or interruption, redundant communication interface 207 and redundant power interface 208 select different wiring paths for delivering data and / or power to CGU 201.

[0031] The RWTU 202 includes a data interface 204b, a cellular transceiver 211, a WLAN transceiver 212 (e.g., Bluetooth (BT), WiFi), a broadcast receiver 213 (e.g., AM / FM radio, satellite radio), and a power supply 214. The data interface 204b includes circuitry for coupling the RWTU 202 to a redundant data link 209. The transceiver 211 supports multiple communication standards, including but not limited to: FM, AM, DAB, Sirius XM, Bluetooth, wireless LAN, 4G / 5G, DSRC, etc. Compared to the WCU 100 shown in Figure 1, the PWCS 200 has an optimized structure that partitions the communication processor circuitry 203 from the transceiver 211. Therefore, the RWTU 202 can be mounted close to antennas 215a-215c to reduce costs associated with the use of wiring harness 109. In an embodiment, the RWTU 202 can be mounted below the top of a vehicle.

[0032] In this embodiment, CGU 201 is coupled to RWTU 202 at data interfaces 204a and 204b. This coupling can be implemented using a high-speed redundant data link 209. In the event of loss or interruption in one of the data links, data interfaces 204a and 204b jointly select a different data link for data transmission. Examples of data interfaces include, but are not limited to, Ethernet, HDBaseT, and PCIe. Examples of data links include, but are not limited to, unshielded twisted pair, shielded twisted pair, coaxial cable, unshielded parallel pairs, shielded parallel cables, and optical media.

[0033] In this embodiment, the main power supply 206 of CGU 201 receives power from the vehicle's power network at a redundant power interface 208 and delivers power to RWTU 202 using redundant power lines 210. For example, each of the redundant power lines 210 may employ a different wiring path within the vehicle. If one of the power lines is damaged or interrupted, the main power supply 206 selects a different power line to supply power to power supply 214 of RWTU 202. Similarly, a backup power supply 205 may be coupled to power supply 214 using redundant power lines 210.

[0034] In one embodiment, redundant data links 209 and redundant power lines 210 are routed within the vehicle for easy inspection and replacement. For example, each data link may be located along a path within the vehicle carrying the power lines. In another example, a harness may deliver both power and vehicle data.

[0035] In this embodiment, RTWU 202 is expandable and can operate with additional wireless communication protocols or standards. For example, RTWU 202 may include an IC kit (e.g., for receiving a dual in-line package) to allow the addition of new chips to support new or newer wireless communication protocols or standards. In this embodiment, antennas 215a-215c may be configured to couple to additional wireless transceivers to communicate with other devices outside the vehicle using added or newer communication standards.

[0036] Example process

[0037] Figure 3 This is a flowchart of a process 300 in which redundant data links and power lines are used in a wireless communication system, according to an embodiment, to transmit data and power respectively from a CGU (e.g., CGU 201) to an RWTU (e.g., RWTU 202). Process 300 can be implemented using hardware (e.g., a central processing unit (CPU), a controller, an ASIC), software, firmware, or any combination thereof.

[0038] Process 300 begins by monitoring a loss or interruption (e.g., quality of service (QoS) degradation) in a first data link or power line in the redundant data link or power line of the CGU and RWTU in the coupled vehicle (301). For example, the loss or interruption of the first data link between the CGU and RWTU could be due to an accident that physically damages the first data link. The data interfaces in the CGU and RWTU include circuitry that monitors data traffic on the first data link and reports any detected loss or interruption to the communication processor circuitry in the CGU. For example, if the data interface in the CGU stops receiving data from the data interface in the RWTU for a specific period of time, or if there is a decrease in data rate, an increase in data errors, and / or a QoS degradation, the data interface in the CGU may report the data loss or interruption to the communication processor circuitry. In an embodiment, monitoring includes port mirroring with a network switch to send a copy of the network packets seen on one switch port to a network monitoring connection on another switch port.

[0039] Process 300 continues by determining, based on monitoring, whether there is loss or interruption in the first data link or the first power line (302). Based on the determination of loss or interruption in the first data link, process 300 continues by selecting a second data link for data transmission between the CGU and the RWTU (303). For example, in response to a reported potential interruption of the first data link, the communication processor circuitry and / or data interface circuitry system in the CGU selects a second data link for transmitting data to the RWTU. The communication processor circuitry and / or data interface circuitry system may first verify that the first data link has been lost or interrupted. For example, the communication processor circuitry and / or data interface circuitry system may enable test data to be transmitted between two data interfaces in the CGU and the RWTU, and if the test data transmission fails, the communication processor circuitry and / or data interface in the CGU selects a second data link for transmitting data between the CGU and the RWTU.

[0040] If there is more than one redundant data link, selection can be based on a priori criteria, where the next highest-ranking data link can be selected to replace the first data link for data transmission. Any desired priori criteria can be used, such as (operational) availability and the electrical or performance characteristics of the data link (e.g., bandwidth, data rate).

[0041] In an embodiment, switching from a first data link to a second data link can be accomplished by one or more managed (e.g., smart switches) or unmanaged network switches in response to commands or instructions from a processor or controller using, for example, Simple Network Management Protocol (SNMP) or any other desired protocol.

[0042] Based on the determination of a loss or interruption in the first power line (302), process 300 continues by selecting a second power line (303) from the main power supply (or backup power supply) in the CGU to the power supply in the RWTU. The second power line can be selected from one or more redundant power lines. For example, the power supply in the RWTU can be configured to monitor (e.g., using a smart power switch) the power delivered from the main power supply in the CGU (e.g., monitoring current and / or voltage input / output), and if a loss or interruption in the first power line is detected, a second power line for coupling to the power supply in the RWTU is selected.

[0043] Process 300 continues by transmitting data on the second data link from CGU to RWTU or by transmitting power on the second power line (304).
