Detailed Description
It should be noted that, without conflict, the embodiments of the present application and features of the embodiments may be combined with each other.
The application will be described in detail below with reference to the drawings in connection with embodiments.

As shown in fig. 1, a wireless receiver 10 of a vehicle according to an embodiment of the present application includes: a receiving component 100, a transmitting component 200 and a control component 300.
Wherein the receiving component 100 is configured to receive a wireless signal of a vehicle. The transmitting component 200 is configured to transmit communication data to a target vehicle-mounted device corresponding to the wireless signal. The control unit 300 is configured to recognize an actual type of the wireless signal, and generate communication data according to the wireless signal to control the transmission unit 200 to transmit the communication data while determining the target in-vehicle device according to the actual type.
Alternatively, in some embodiments, the communication data may be LIN data, or K communication data, which is not specifically limited herein.
The receiving component 100 may be an RF receiver, the RF receiver may receive a wireless signal through an RF antenna, the transmitting component 200 may be a LIN transceiver, the target vehicle-mounted device may be a PEPS system of a vehicle, or may be a tire pressure monitoring system of a vehicle, which is not limited herein; the actual kind of the wireless signal may be a function of the current wireless signal, for example, a tire pressure function, or a key function, etc.
To facilitate further understanding of the wireless receiver 10 of the vehicle according to an embodiment of the present application, a detailed description is provided below in conjunction with fig. 2.
For example, as shown in fig. 2, fig. 2 is a block schematic diagram of a wireless receiver of a vehicle according to an embodiment of the application. The wireless receiver of the vehicle includes: an RF Receiver (RF Receiver), an MCU (Microcontroller Unit, micro control unit) and a LIN transceiver (LIN transmitter). The RF receiver, i.e. the receiving component 100, the MCU, i.e. the control component 300, the LIN transceiver, i.e. the transmitting component 200, the LIN transceiver may be configured to receive and transmit bus data (i.e. wireless signals), the interface circuit of LIN meets international standards, serial communication is performed between the LIN transceiver and the MCU, and the RF receiver and the MCU communicate through SPI (Serial Peripheral Interface ).
Specifically, the RF receiver according to the embodiment of the present application may receive a wireless signal through an RF antenna, the MCU identifies an actual type of the wireless signal, obtains a function of the wireless signal, determines a corresponding target in-vehicle device according to the obtained function of the wireless signal, for example, if the function of the wireless signal is a tire pressure function, the corresponding target in-vehicle device is a tire pressure monitoring system of a vehicle, if the function of the wireless signal is a tire key function, the corresponding target in-vehicle device is a PEPS system of the vehicle, and generates communication data from the wireless signal after determining the corresponding target in-vehicle device.
Wherein, in some embodiments, the control assembly 300 comprises: a first generation unit and a second generation unit. The first generation unit is used for generating a function code of communication data according to the actual type; and the second generating unit is used for obtaining the communication data of the data area in the communication data according to the wireless signal.
It should be understood that, because the actual types of the wireless signals are different, the corresponding data lengths (such as the lengths of the key data and the tire pressure data) are also different, the embodiment of the application can generate the function code of the communication data according to the actual types, so that the function (i.e. the actual types) of the currently transmitted data frame, such as the key function and the tire pressure function, is represented by the function code.
It should be noted that, taking the key data and the tire pressure data as examples, since the lengths of the key data and the tire pressure data are not fixed lengths, and the communication data are standard lengths, when the LIN data is transmitted, the effective data length of the current frame needs to be noted in the data, and in order to ensure the reliability of each transmission data, the maximum data should not exceed 100 bytes. Thus, the decline of the function execution efficiency caused by the long data time-sharing transmission can be avoided.
Further, in some embodiments, the control assembly 300 further comprises: and a third generation unit. The third generating unit is used for generating an error check code of the communication data according to the wireless signal.
It should be understood that, in order to ensure accuracy during transmission of communication data, the embodiment of the present application may generate an error check code of the communication data to generate an error check code of the communication data, for example, increase a CRC (Cyclic Redundancy Check ) check in the process of transmitting the communication data, where the check position is from the function code to the valid data before the CRC.
Further, in some embodiments, the control assembly 300 further comprises: and a fourth generation unit. The fourth generating unit is used for determining an address code of the communication data according to the identity of the target vehicle-mounted device and the identity of the wireless signal.
The identity of the target vehicle-mounted device and the identity of the wireless signal can be set by a user, for example, the identity of the target vehicle-mounted device and the identity of the wireless signal are set at the head of the communication data.
Specifically, since the transmission of the communication data requires a receiving party, the receiving party confirms whether to receive the data by the identification ID (Identity document, identification number), and thus the header of the communication data may contain a data ID in which the transmission ID and the target reception ID may be specified in order to avoid erroneous reception of the data by an irrelevant receiving party.
Further, in some embodiments, the sending component 200 is further configured to match the best sending mode according to the actual priority of the communication data, and send the communication data according to the best sending mode.
It should be understood that, considering that there are multiple nodes (parts) of the transmission bus, in order to avoid collision of data transmission, each node needs to make priority judgment when transmitting data, the master node of the LIN has priority higher than the slave node, and confirms whether there is collision of data transmission by way of read-back when transmitting communication data, and if there is collision, enables priority policy for data retransmission.
For example, assuming that there are communication data of the key function, communication data of the tire pressure function, and communication data of the engine function, the embodiment of the present application may preset priorities among the communication data of the key function, the communication data of the tire pressure function, and the communication data of the engine function, for example, the communication data of the key function has a priority greater than that of the communication data of the engine function, and the communication data of the engine function has a priority greater than that of the communication data of the tire pressure function; when data is transmitted through the node, if the communication data of the key function, the communication data of the tire pressure function and the communication data of the engine function are simultaneously received, the embodiment of the application preferentially transmits the communication data of the key function, then transmits the communication data of the engine function and finally transmits the communication data of the tire pressure function.
It should be noted that the foregoing examples are merely exemplary, and are not intended to limit the present application, and those skilled in the art may set the priority according to actual situations, which are not specifically limited herein.
In addition, the software protocol layer of the embodiment of the application does not use the LIN protocol layer, but performs data filling according to the data content and sends the data to the LIN transceiver, and the LIN transceiver performs data analysis according to the format after receiving the data with the same format.
According to the wireless receiver of the vehicle, which is disclosed by the embodiment of the application, the wireless signal of the vehicle can be received, the actual type of the wireless signal is identified, the target vehicle-mounted device is determined according to the actual type, and meanwhile, the communication data is generated according to the wireless signal, so that the transmission component is controlled to transmit the communication data, and the communication data is transmitted to the target vehicle-mounted device corresponding to the wireless signal. Therefore, the problems that in the related art, the vehicle is complex to arrange due to the fact that different radio frequency receiving devices are required for different system settings, and the vehicle cost is high are solved, the different radio frequency receiving devices are not required for different system settings, and the vehicle cost is effectively reduced.

According to the wireless communication method of the vehicle, which is provided by the embodiment of the application, the wireless signal of the vehicle is received, the actual type of the wireless signal is identified, the target vehicle-mounted device is determined according to the actual type, and meanwhile, communication data is generated according to the wireless signal, so that the transmission component is controlled to transmit the communication data and the communication data is transmitted to the target vehicle-mounted device corresponding to the wireless signal.
