[0026] Vehicle-assisted driving systems (AVSs) are a key technology for active safety in modern vehicles, providing assistance and support to drivers in complex traffic environments and during vehicle maneuvers. Using vehicle sensors and computer algorithms, AVSs collect data on the vehicle's internal and external environments, performing technical processing such as static and dynamic object recognition, detection, and tracking. This allows drivers to proactively identify potential hazards, effectively improving driving comfort and safety. Examples of AVSs include lane keeping assist systems, automatic parking assist systems, brake assist systems, reverse assist systems, and driving assistance systems.

[0027] The assisted driving controller is a core component of the vehicle's assisted driving system. It acquires and processes data from the vehicle's internal and external environments collected by the vehicle's sensors, and controls the execution of assisted driving functions. The assisted driving controller typically includes a positioning module, which is used for vehicle navigation and precise positioning and plays a vital role in the assisted driving controller. In existing assisted driving controllers, the positioning module is typically located on the same circuit board as the other modules of the assisted driving controller. Therefore, when testing the positioning module, the circuit board needs to be redesigned and placed on it for testing.

[0028] refer to Figure 1 , which shows a structural schematic diagram of a vehicle-mounted positioning module 100 proposed according to an embodiment of the present application. In the figure, the solid line refers to the electrical connection wire, and the dotted line refers to the communication connection wire. The vehicle-mounted positioning module 100 includes a circuit board 1 independent of the assisted driving controller, and a board-to-board connector 2 is provided on the circuit board 1. The vehicle-mounted positioning module 100 is connected to the assisted driving controller through the board-to-board connector 2, and in particular, they are not only electrically connected but also communicatively connected to each other, so that the positioning signal in the vehicle-mounted positioning module 100 is transmitted to the assisted driving controller through the board-to-board connector 2. Positioning modules 31, 32 connected to the board-to-board connector 2 and an antenna connector 4 connected to the positioning modules 31, 32 are also provided on the circuit board 1. In this way, the antenna signal of the antenna connector 4 is transmitted to the board-to-board connector 2 after being processed by the positioning modules 31, 32, and is transmitted to the assisted driving controller via the board-to-board connector 2.

[0029] Optionally, the circuit board 1 is provided with solder pads for a standard positioning module and operating circuitry compatible with the standard positioning module. The positioning modules used in assisted driving controllers are generally standardized and have the same package dimensions. This allows the circuit board to be compatible with various positioning modules. Installation requires simply soldering the positioning module to the solder pads and matching it with the corresponding operating circuitry.

[0030] In one embodiment of the present application, the vehicle-mounted positioning module 100 includes at least two different positioning modules 31 and 32, which are respectively used to process antenna signals of different frequency bands. The positioning modules include, for example, at least two of the following: GPS (Global Positioning System) positioning module, Beidou positioning module, GNSS (Global Navigation Satellite System) positioning module and GLONASS (Global'naya Navigatsionnaya Sputnikovaya Sistema) positioning module. Figure 1 In the embodiment, the vehicle-mounted positioning module 100 includes two positioning modules 31 and 32, and the two positioning modules 31 and 32 are respectively connected to an antenna connector 4. It is understood that the vehicle-mounted positioning module 100 can have different numbers of positioning modules in different application scenarios, such as one positioning module or more than two positioning modules, and multiple positioning modules can be connected to one antenna connector or to multiple antenna connectors.

[0031] In one embodiment of the present application, power conversion modules 51 and 52 are electrically connected between the board-to-board connector 2 and the positioning modules 31 and 32 to supply power to the positioning modules 31 and 32 via the auxiliary driving controller via the power conversion modules 51 and 52. The power conversion modules 51 and 52 can be configured as DC / DC converters, for example, which convert the higher voltage DC power transmitted from the auxiliary driving controller into a lower DC power supply to supply power to the positioning modules 31 and 32. In the case of multiple positioning modules, for example, a power conversion module can be provided for each positioning module. It should be understood that multiple positioning modules can also share one power conversion module.

[0032] Alternatively, an independent power supply module may be provided on the circuit board 1 of the vehicle-mounted positioning module 100, which independently supplies power to the positioning modules 31 and 32 via a power conversion module. With this configuration, the vehicle-mounted positioning module does not require an external power supply, nor does it require power from the controller, and can independently complete testing without an external power supply. Alternatively, if the power supply module is configured as a DC power supply that can provide a suitable and accurate power supply to the positioning module, the power conversion module on the circuit board can be omitted.

[0033] In one embodiment of the present application, the power conversion modules 51 and 52 include a power chip component, and a replaceable voltage feedback resistor is provided on the power chip component to adjust the output voltage of the power chip component. In this case, if you want to adjust the output voltage of the power chip component, you only need to replace the voltage feedback resistor provided thereon. The voltage feedback resistor is preferably connected in series with the positioning modules 31 and 32 in the circuit. At this time, if you want to reduce the output voltage of the power chip component, you need to increase the resistance of the voltage feedback resistor.

[0034] In one embodiment of the present application, the power conversion modules 51 and 52 are also configured to monitor the voltage and current output by the power chip components with the help of the voltage monitoring module and the current monitoring module of the assisted driving controller to prevent the output voltage and current from being too large and damaging the positioning module or other circuit board components. In an optional case, the voltage output end of the power conversion modules 51 and 52 is connected to the voltage monitoring module of the assisted driving controller via the board-to-board connector 2 to monitor the output voltage of the power conversion modules 51 and 52. When the voltage monitoring module detects that the output voltage of the power conversion modules 51 and 52 is too large, it reduces the voltage output by the controller to the vehicle positioning module 100 or disconnects the electrical connection between the controller and the vehicle positioning module 100. In another optional case, a current sensor is provided on the power conversion modules 51 and 52, which is connected to the board-to-board connector 2. The current sensor monitors the output current of the power conversion modules 51 and 52 and transmits it to the current monitoring module of the assisted driving controller via the board-to-board connector 2 to monitor the output current of the power conversion modules 51 and 52. When the current monitoring module detects that the output current of the power conversion modules 51 and 52 is too large, the current output by the controller to the vehicle positioning module 100 is reduced or the electrical connection between the controller and the vehicle positioning module 100 is disconnected.

[0035] In one embodiment of the present application, a POC circuit for powering the antenna and a filter circuit for processing RF signals are connected between the positioning modules 31, 32 and the antenna connector 4. Figure 1 Not shown, it is arranged in the form of an integrated circuit on the circuit board 1. In a preferred embodiment, the distance between the positioning modules 31, 32 and the antenna connector 4, in particular the length of the signal line between the positioning modules 31, 32 and the antenna connector 4, is set as small as possible, in particular, less than the length of the signal line between the positioning modules 31, 32 and the board-to-board connector 2. The signal lines are spaced apart from each other to ensure insulation, thereby ensuring the transmission of the RF signal from the antenna connector 4 to the positioning modules 31, 32.

[0036] In one embodiment of the present application, the positioning modules 31 and 32 are connected to the board-to-board connector 2 via a serial communication line or a low-speed signal line. The positioning modules 31 and 32 receive radio frequency signals from the antenna connector 4, process them, and transmit them to the board-to-board connector 2 via the serial communication line or the low-speed signal line.

[0038] Another aspect of the present application further provides a vehicle comprising the aforementioned assisted driving controller. The vehicle also has all the technical advantages of the aforementioned vehicle-mounted positioning module 100, which will not be further elaborated herein.
