Abstract
Description
Technical Field
[0001] The present application relates to the technical field of vehicles, and in particular, to an intelligent keyless system and a vehicle. Background Art
[0002] In the related art, there are many Bluetooth modules in the PEPS system (Passive Entry Passive Start, intelligent keyless system, i.e., intelligent entry and start system) and the TPMS system (tire pressure monitoring system) on the whole vehicle. The PEPS system generally has a communication topology of one master and multiple anchor points. Among them, the master node mainly communicates with the Bluetooth key, and the multiple anchor points are used to assist in positioning the position of the Bluetooth key. Each of the master node and each anchor point requires a Bluetooth module; for example, the Bluetooth master node module and multiple Bluetooth anchor point modules in the Bluetooth key system. The TPMS system generally consists of multiple tire pressure sensors and a receiver. In heavy truck vehicles, because the tire pressure sensors are far from the receiver, a repeater is also added to ensure the effective transmission of data. If the trailer also needs to add tire pressure sensors, the number of sensors is too large, and even multiple repeaters need to be added. The more the number of Bluetooth modules, the higher the cost of the whole vehicle. Summary of the Invention

By integrating the tire pressure monitoring system and the intelligent keyless system, while realizing the functions of tire pressure monitoring and keyless entry and start, the number of Bluetooth modules is reduced, and thus, the cost of the whole vehicle is effectively reduced.

After receiving the MAC address of the tire pressure sensor, the corresponding Bluetooth anchor stores it.
[0013] In some examples, multiple of the Bluetooth anchors are connected to the main node through Bluetooth.
[0014] In some examples, when multiple of the Bluetooth anchors are connected to the main node through Bluetooth, it further includes:
[0015] The Bluetooth anchor acts as a broadcaster and communicates with the main node;
[0016] The master node provides a scanning connection with the Bluetooth anchor points to scan according to the MAC addresses of the preset Bluetooth anchor points and establish communication with the Bluetooth anchor points.

[0024] Figure 1 It is a structural block diagram of the intelligent keyless system provided by the embodiment of the present application;
[0025] Figure 2Topological diagram of the intelligent keyless system provided by the embodiments of the present application. Detailed implementation manners
[0026] The present application will be further described in detail below in conjunction with embodiments and the accompanying drawings. It can be understood that the specific embodiments described herein are only used to explain the related application, rather than limiting the application. Additionally, it should be noted that for the convenience of description, only the parts related to the application are shown in the drawings.
[0027] It should be noted that, without conflict, the embodiments and features of the embodiments in the present application can be combined with each other. The present application will be described in detail below with reference to the drawings and in conjunction with the embodiments.
[0028] The intelligent keyless system and vehicle according to the embodiments of the present application will be described in detail below with reference to the drawings.
[0029] Figure 1 is a structural block diagram of an intelligent keyless system according to an embodiment of the present application. As Figure 1 shown, the intelligent keyless system according to the embodiments of the present application includes: a Bluetooth anchor point 110 and a main node 120, wherein:
[0030] There are multiple Bluetooth anchor points 110, and the multiple Bluetooth anchor points 110 are used to monitor the field strength value of the Bluetooth signal of the Bluetooth key. Each Bluetooth anchor point 110 is further used to perform Bluetooth communication with at least one tire pressure sensor to relay the corresponding tire pressure data. The main node 120 is used to monitor the Bluetooth key signal, and is connected to the multiple Bluetooth anchor points 110 to locate the Bluetooth key according to the field strength value of the Bluetooth signal of the Bluetooth key sent by the multiple Bluetooth anchor points 110, and to respond to the Bluetooth key according to the positioning result and the Bluetooth key signal, and to forward the tire pressure data relayed by each Bluetooth anchor point 110 to the CAN network.
[0031] As a specific example, as Figure 2 shown, the multiple Bluetooth anchor points 110 include a left anchor point arranged on the left side of the vehicle (such as the left anchor point on the left side of the vehicle shown in Figure 2 ) and a right anchor point arranged on the right side of the vehicle (such as the right anchor point on the right side of the vehicle shown in Figure 2 ). Among them, the left anchor point is used to perform Bluetooth communication with the tire pressure sensors of the wheels on the left side of the vehicle (such as one or more tire pressure sensors on the left side of the vehicle shown in Figure 2 ) to relay the tire pressure data of the tire pressure sensors of the wheels on the left side of the vehicle, and the right anchor point is used to perform Bluetooth communication with the tire pressure sensors of the wheels on the right side of the vehicle (such as one or more tire pressure sensors on the right side of the vehicle shown in Figure 2 ) to relay the tire pressure data of the tire pressure sensors of the wheels on the right side of the vehicle.
[0032] Specifically, as shown in Figure 2 , the tire pressure repeater in the existing Tire Pressure Monitoring System (TPMS) is cancelled, and the Bluetooth anchor of the Passive Entry Passive Start system (PEPS) is used to implement the function of tire pressure data relay. In addition, the receiver in the TPMS system is cancelled, and the main node in the PEPS system is used to receive the tire pressure data.
[0033] As shown in Figure 2 , the vehicle is divided into left and right parts by the vehicle's central axis. The left anchor relays the tire pressure sensor on the left to the main node, and the right side is similar. Each Bluetooth anchor transmits the tire pressure data and the field strength data (field strength value) of the monitored Bluetooth key to the main node. After receiving the data, the main node forwards the tire pressure data to the CAN network of the whole vehicle. The instrument can obtain the tire pressure data from the CAN network for display. At the same time, the main node locates the Bluetooth key using the received field strength value and forwards the location information to the CAN network of the whole vehicle. The main node communicates with the Bluetooth key and forwards the key information of the Bluetooth key to the CAN network of the whole vehicle.
[0034] In an embodiment of the present application, the main node is integrated on the Body Control Module (BCM), that is: the main node is not a separate ECU, but is integrated into the BCM. The key information of the Bluetooth key does not need to be forwarded to the CAN network of the whole vehicle, but is transmitted to the BCM, and the BCM controls the locking and unlocking of the vehicle.
[0035] In an embodiment of the present application, the multiple Bluetooth anchors are connected to the main node through a CAN bus or a LIN bus. Among them, the tire pressure sensor acts as a broadcaster and broadcasts the tire pressure data at a predetermined first time period. When the Bluetooth anchor communicates with the corresponding tire pressure sensor, it acts as a scanner and scans according to the pre-stored MAC address of the tire pressure sensor to obtain the tire pressure data. When the tire pressure data of the corresponding tire pressure sensor is not received within a preset time, it diagnoses the tire pressure sensor failure and issues an alarm. When the Bluetooth anchor monitors the Bluetooth key, it acts as a listener and obtains the field strength value of the Bluetooth signal of the Bluetooth key according to the preset MAC address of the Bluetooth key. The Bluetooth key acts as a broadcaster and broadcasts data at a predetermined second time period. The main node acts as a scanner and scans according to the preset MAC address of the Bluetooth key to communicate with the Bluetooth key.
[0036] In the above example, the preset method for the MAC address of the Bluetooth key is as follows: The MAC address of the Bluetooth key is written to the master node on the diagnostic CAN node through the UDS protocol. After receiving the MAC address of the Bluetooth key, the master node stores it and forwards the MAC address of the Bluetooth key to the Bluetooth anchor point. After receiving the MAC address of the Bluetooth key, the Bluetooth anchor point stores it. The preset method for the MAC address of the tire pressure sensor is as follows: The MAC address of the tire pressure sensor is sent to the master node on the diagnostic CAN node through the UDS protocol. The master node forwards the MAC address of the tire pressure sensor to the corresponding Bluetooth anchor point, and the corresponding Bluetooth anchor point stores the MAC address of the tire pressure sensor after receiving it.
[0037] Specifically, for the tire pressure sensor: As a broadcaster, it broadcasts tire pressure data at a time period of seconds. The anchor point (i.e., the Bluetooth anchor point): When communicating with the tire pressure sensor, as a scanner, it scans according to the pre-stored MAC address of the tire pressure sensor, communicates with the tire pressure sensor, and obtains the tire pressure data. It can also diagnose the absence of a certain tire pressure sensor. For example, if 5 MAC addresses are preset in the installation order and the tire pressure data of the first MAC address cannot be obtained for a certain period of time, it means that the tire pressure sensor is faulty and an alarm is issued. When monitoring the Bluetooth key, it actually exists as a listener, does not communicate with the Bluetooth key, and only obtains its field strength value according to the preset key MAC address.
[0038] For the Bluetooth key: As a broadcaster, it broadcasts data at a cycle of 50 ms. The master node: As a scanner, it scans according to the preset Bluetooth key mac and communicates with the Bluetooth key.
[0039] The scheme for presetting the MAC address: Whether the master node is integrated into the BCM or not, it needs to be connected to the vehicle's diagnostic CAN. When the vehicle is off the production line, the MAC addresses are preset and written to the master node and the anchor point. Presetting the key MAC address: The key MAC address is written to the master node on the diagnostic CAN through the UDS protocol. After receiving the key MAC address, the master node stores it and forwards the key MAC address to the left and right anchor points. After receiving the MAC address, the anchor points store it, as shown in Table 1:
[0040] Table 1
[0041] Byte0 Byte1-byte6 Byte7 Key Number Key MAC Address Crc Check
[0042] Presetting the MAC address of the tire pressure sensor: The MAC address of the tire pressure sensor is sent to the master node on the diagnostic CAN through the UDS protocol. The master node forwards the MAC address of the tire pressure sensor to the corresponding anchor point, and the anchor point stores the MAC address after receiving it, as shown in Table 2:
[0043] Table 2
[0044]
[0045] In the above example, the Bluetooth anchor points and the master node are connected through the CAN bus / LIN bus. If the wired connection is changed to a Bluetooth connection, the connection of the CAN bus / LIN bus can be saved, achieving the purpose of further reducing costs. Therefore, the embodiments of the present application also need to add the following settings:
[0046] When the multiple Bluetooth anchor points are connected to the master node via Bluetooth, it further includes: the Bluetooth anchor points act as broadcast parties to communicate with the master node; the master node provides a scanning connection with the Bluetooth anchor points to scan according to the preset MAC address of the Bluetooth anchor points and establish communication with the Bluetooth anchor points. Among them: before the MAC address of the preset Bluetooth key and the MAC address of the tire pressure sensor, the MAC address of the preset Bluetooth anchor point is added. The method of adding the MAC address of the preset Bluetooth anchor point is: writing the MAC address of the Bluetooth anchor point to the master node on the diagnostic CAN node through the UDS protocol. After receiving the MAC address of the Bluetooth anchor point, the master node stores it and triggers the master node to scan the Bluetooth anchor point to establish communication with the Bluetooth anchor point.
[0047] Specifically, for the anchor points: the role of the broadcast party needs to be added to communicate with the master node; for the master node: the scanning connection processing with the anchor points needs to be added. According to the preset MAC address of the anchor points, scanning is performed and a connection is established with the anchor points for communication.
[0048] Before the MAC address of the preset key and the MAC address of the tire pressure sensor (must), the MAC address of the preset anchor point needs to be supplemented and added.
[0049] Adding the MAC address of the preset anchor point: writing the MAC address of the anchor point to the master node on the diagnostic CAN through the UDS protocol. After receiving the MAC address of the anchor point, the master node stores it and triggers the master node to scan the anchor point to establish a connection for communication. As shown in Table 3:
