[0040] The term "comprising" and variations thereof as used herein are used inclusively, that is, "comprising but not limited to." The term "based on" is "based at least in part on." The term "one embodiment" means "at least one embodiment." The term "another embodiment" means "at least one additional embodiment." The term "some embodiments" means "at least some embodiments." Related definitions of other terms will be given in the description below.

[0041] It should be noted that the terms "first", "second", and the like in the present disclosure are merely used to distinguish different devices, modules or units, and do not limit the functions performed by these devices, modules or units.

[0042] It should be noted that the terms "one", "multiple" in the present disclosure are illustrative and not restrictive, and those skilled in the art should understand that unless otherwise explicitly stated in the context, it should be understood as "one or more".

[0043] As described above, the current multi-node Bluetooth key (a Bluetooth key composed of one Bluetooth master module and multiple Bluetooth antennas) realizes positioning through the strength of the Bluetooth signal, but the strength of the Bluetooth signal is disturbed by factors such as human bodies and the environment, and the positioning accuracy has errors. At present, the positioning accuracy has a deviation range of 1-5m. This leads to the Bluetooth key constantly waking up the vehicle network in the preset critical area, such as within a range of 50m from the vehicle, resulting in an increase in the static power consumption of the vehicle, thereby increasing the risk of power supply to the vehicle.

[0044] Based on the above problems, the preset critical region is considered comprehensively in combination with other working conditions, such as a Bluetooth connection state, a CAN network, a positioning mode and the like, so that the working mode is switched according to different working conditions in the critical region, thereby avoiding the influence of the positioning accuracy on the condition of using the preset critical region and the influence of the need to constantly wake up the vehicle network. In this way, the risk of vehicle power supply is reduced.

[0045] In order to better illustrate the embodiments of the present application, first, the application scenario of the mode switching method provided by the present application is introduced.

[0046] Referring to Figure 1 The application scenario of the mode switching method provided by the present application is shown in the figure. In the embodiments of the present application, the mode switching method is applied to a Bluetooth low energy (BLE) system. The BLE system includes:

[0047] A mobile phone 103 on the mobile phone side, a vehicle control unit 101 on the vehicle side, a Bluetooth module 102, and a Bluetooth antenna. In the embodiments of the present application, the number of Bluetooth antennas is 3, which is only illustrative, and can be adjusted as needed.

[0048] The vehicle control unit 101 transmits data with the Bluetooth module 102 through CAN communication, and combines the Bluetooth antenna to jointly complete the positioning of the vehicle by the mobile phone through 2.4G Bluetooth communication.

[0049] In the embodiments of the present application, the Bluetooth module includes a Bluetooth master chip and a security chip, wherein the Bluetooth master chip is used to wake up the Bluetooth work, and the security chip is used to determine the security connection of the Bluetooth. The CAN communication is completed through the CAN bus. In the embodiments of the present application, the CAN bus includes a release state and a request state. The release state indicates that the CAN bus has no communication, and the request state indicates that the CAN bus is in communication. The Bluetooth module 102 wakes up the vehicle network through CAN communication, and the vehicle control unit 102 performs mobile phone positioning through CAN communication.

[0050] In the embodiments of the present application, the mobile phone 103 and the Bluetooth module 102 communicate with each other through 2.4G high-frequency communication to realize mobile phone positioning. The 2.4G high-frequency communication can be adjusted as needed.

[0051] The mode switching method provided by the present application is introduced below in combination with the BLE system. Referring to Figure 2 The mode switching method provided by the present application includes the following steps:

[0052] S201: When the connection distance of the mobile phone from the vehicle is lower than a preset threshold, the current working condition and the first working mode are obtained.

[0053] In the embodiment of the present application, when the vehicle BLE system acquires the connection distance of the mobile phone from the vehicle, the relationship between the connection distance and the preset threshold is determined. When the connection distance is lower than the preset threshold, the BLE system acquires the current working condition and the current working mode, i.e., the first working mode.

[0054] In a possible implementation, the vehicle is provided with a radar, and the radar acquires the connection distance of the mobile phone from the vehicle through a radar signal and sends the connection distance to the BLE system.

[0055] Exemplary illustration: assuming that the preset threshold is 50 m, when the connection distance acquired by the BLE system is 10 m, which is lower than the preset threshold, the BLE system acquires the current working condition and the first working mode.

[0056] In the embodiment of the present application, the current working condition involves the current Bluetooth connection state, the positioning method, the CAN network state, etc. Among them, the Bluetooth connection state includes whether the pairing is successful, whether the Bluetooth identity authentication is passed, etc., the positioning method includes the functional area where the mobile phone is located, the time when the mobile phone is located in the functional area, and whether the positioning changes in the functional area, etc. The CAN network includes whether the CAN is in the release state or in the request state, etc.

[0057] For the division of the functional area, see Figure 3 , which will not be discussed here.

[0058] The first working mode is the working mode of the current BLE system. In the embodiment of the present application, the BLE system works from sleep to normal work to sleep, and its working mode can be subdivided into five working modes according to the Bluetooth connection state, the positioning method, and the CAN network, including the first pre-working mode, the second pre-working mode, the normal mode, the low-power mode, and the sleep waiting mode. The specific conditions of the first pre-working mode, the second pre-working mode, the normal working mode, the low-power mode, and the sleep waiting mode are shown in Table 1 below. Here, they will not be discussed.

[0059] S202: determining the first switching relationship between the preset working condition and the working mode according to the first working mode.

[0060] In the embodiment of the present application, the BLE system pre-sets the corresponding relationship between the working mode and the switching relationship, and the switching relationship is the switching relationship between the preset working condition and the working mode. According to the first working mode and the corresponding relationship between the preset working mode and the switching relationship, the first switching relationship corresponding to the first working model is determined. That is, the first switching relationship between the preset working condition and the working mode is determined.

[0061] In a possible implementation, when the first working mode is the low-power mode, the first switching relationship is that, when the preset working condition is a Bluetooth wake-up condition, such as vehicle power-on or other Bluetooth wake-up conditions, the low-power mode is switched to the first preset working mode.

[0062] In a possible implementation, when the first working mode is the first preset working mode, the first switching relationship is that, if the preset working condition is a safe connection condition, such as Bluetooth authentication, the first preset working mode is switched to the second preset working mode. When the preset working condition is a first sleep waiting condition, such as an illegal Bluetooth connection and a CAN network in a release state, a Bluetooth wake-up time exceeding a preset time threshold, and the like, the first preset working mode is switched to the sleep waiting mode.

[0063] In a possible implementation, when the first working mode is the second preset working mode, the first switching relationship is that, if the preset working condition is a second sleep waiting condition, such as a legal Bluetooth connection and a Bluetooth wake-up time exceeding a preset time threshold, but the CAN network is in a release state, the second preset working mode is switched to the sleep waiting mode; if the preset working condition meets a first normal working condition, such as a CAN network in a request state, the second preset working mode is switched to the normal working mode. When the preset working condition is a first return condition, such as the Bluetooth not being in a safe connection state, the second preset working mode is switched to the first preset working mode.

[0064] In a possible implementation, when the first working mode is the normal working mode, the first switching relationship is that, if the preset working condition meets a third sleep waiting condition, such as the normal working mode lasting more than 1 s, the normal working mode is switched to the sleep waiting mode. When the preset working condition meets the first return condition, the normal working mode is switched to the first preset working mode.

[0065] In a possible implementation, when the first working mode is the sleep waiting mode, the first switching relationship is that, if the preset working condition meets a second return condition, such as Bluetooth wake-up and not being in a node mode, the sleep waiting mode is switched to the first preset working mode. If the preset working condition meets a second normal working condition, such as a legal Bluetooth access and Bluetooth authentication, and the CAN network is in a request state, the sleep waiting mode is switched to the normal working mode. If the preset working condition meets a low-power condition, the sleep waiting mode is switched to the low-power mode.

[0066] In the embodiment of the application, the process of switching the sleep waiting mode to the low-power mode is irreversible, and when the low-power mode is switched to the sleep waiting mode, the BLE system needs to be reset.

[0067] S203: Switching the first working mode to the second working mode based on the first switching relationship according to the current working condition.

[0068] In the embodiments of the present application, for the current working condition satisfying the safe connection condition and the first working mode being the first pre-working mode, the second working mode is the second pre-working mode. For the current working condition satisfying the first sleep waiting condition and the first working mode being the first pre-working mode, the second working mode is the sleep waiting mode. For the first working mode being other working modes, such as the second pre-working mode, the normal working mode, etc., the second working mode is obtained according to the switching relationship of step S202.

[0069] Table 1 BLE system working mode division table

[0070]

[0071] Referring to Table 1, a BLE system working mode division table provided in the embodiments of the present application is provided. The first pre-working mode is that the main module is in an awake state, there is a Bluetooth connection, but no safe connection is established (at this time, the security chip is in a normal working state), and no CAN message is actively sent (the CAN is in a released state), at this time, the Bluetooth antenna is closed.

[0072] The second pre-working mode is that the main module is in an awake state, there is a legal mobile phone Bluetooth connection, i.e., the pairing is successful, and a safe connection is established (at this time, the security chip is in a normal working state), at this time, the Bluetooth antenna is opened, but no CAN message is actively sent. At this time, no mobile phone positioning is performed.

[0073] The normal mode is that the main module is in an awake state, there is a legal mobile phone Bluetooth connection, the Bluetooth antenna is opened, the CAN communication is started, and the mobile phone is positioned through multiple Bluetooth antennas.

[0074] The low-power mode is that the main module is in a low-power state, at this time, no CAN message is actively sent. At this time, according to the Bluetooth safe connection state, it is determined whether the security chip is in a normal working state, and the Bluetooth antenna is closed.

[0075] The sleep waiting mode is that the system notifies the Bluetooth main module to enter a low-power state, and waits for several seconds to ensure that the Bluetooth is in a low-power state. At this time, no CAN message is actively sent, and the Bluetooth antenna state is consistent with the previous state. At this time, according to the Bluetooth safe connection state, it is determined whether the security chip is in a normal working state.

[0076] Referring to Figure 3Fig. 1 is a schematic diagram of the division of the functional area provided by the embodiment of the present application. Among them, region 1 is the in-vehicle area, region 2 is the main driver passive unlocking and automatic unlocking area, region 3 is the co-driver passive unlocking and automatic unlocking area, region 6 is the rear door passive unlocking area, and region 7 is the wake-up area, including regions 2, 3 and 6.

[0077] Other areas are all areas except regions 1 and 7, and Bluetooth unconnected areas.

[0078] Among them, region 2 is the area within 1.5m from the main driver door of the vehicle; region 3 is the area within 1.5m from the co-driver door of the vehicle; and region 6 is the area within 1.5m from the rear door of the vehicle.

[0079] The mode switching method disclosed by the present application first acquires the current working condition and the first working mode when the distance between the mobile phone and the vehicle is lower than the preset threshold. The first working mode is used to indicate the working mode of the Bluetooth BLE system. The switching relationship between the working condition and the working mode in the first working mode is determined. According to the current working condition, the first working mode is switched to the second working mode based on the switching relationship. In this way, the Bluetooth BLE system is switched when the preset switching condition and the distance from the vehicle are met. The influence of the positioning accuracy on the distance from the vehicle is avoided, the influence of the constant wake-up of the vehicle network is avoided, and the risk of vehicle power supply is reduced.

[0080] In order to switch the Bluetooth module between different working modes through software adjustment, the present application embodiment counts the specific working conditions involved in the BLE system working, and designs the following working mode switching relationship diagram according to the specific working conditions.

[0081] Table 2 Working condition table

[0082]

[0083] Referring to Table 2, the working condition table provided by the present application embodiment. Among them, the working condition includes at least one of A, B, C, D, E, G, H, J, K, L, N, P, Q, R, S or T conditions. The above conditions are specifically shown in Table 2, which will not be discussed here.

[0084] According to Table 2, the logical relationship between the BLE system built-in working condition and the working mode switching. Referring to Figure 4 A schematic diagram of the working mode switching relationship provided by the embodiment of the present application. That is, by constructing the above working table and the switching relationship of the working mode, and embedding the above switching relationship in the BLE system, so that the BLE system determines the current working mode switching mode according to the current working condition and the current corresponding relationship.

[0085] As Figure 4 shown, when the Bluetooth module is in low power consumption mode, and the condition!E||N||G||J (i.e. Bluetooth wake-up condition) is met, including CAN being in request state, or Bluetooth wake-up, or receiving Bluetooth operation control instruction, or Bluetooth identity verification passing, the Bluetooth module will be woken up, and the BLE system will enter the first pre-working mode.

[0086] When the BLE system is in the first pre-working mode, if the condition A&L (safe connection condition) is met, i.e. Bluetooth pairing is successful, and Bluetooth identity verification is passed, the BLE system enters the second pre-working mode. If the condition!A&K&E||R&E (i.e. first sleep waiting condition) is met, the first sleep waiting time includes two cases, one is that pairing is not successful, the master module is started or woken up for more than 5s, and the CAN is in BUS SLEEP or BUS OFF condition, and the other is that the CAN signal of receiving node mode signal is not in normal working mode, and the CAN is in BUS SLEEP or BUS OFF condition. At this time, the BLE system enters the sleep waiting mode.

[0087] When the Bluetooth module is in the second pre-working mode, if the Bluetooth module meets the condition A&L&D&K&E||R&E (i.e. second sleep waiting condition), i.e. including two cases, one is that pairing is successful, and Bluetooth identity verification is passed, and the mobile phone is in other area for more than 10 min, and the MCU is started or woken up for more than 5s, and the CAN is in BUS SLEEP or BUS OFF condition. The second is that pairing is successful, and Bluetooth identity verification is passed, and the mobile phone is in other area for more than 10 min, and the CAN signal of receiving node mode signal is not in normal working mode, and the CAN is in BUS SLEEP or BUS OFF condition. At this time, the BLE system enters the sleep waiting mode.

[0088] If the condition A&L&(B||G) (i.e. first normal working condition) is met, including pairing is successful, and Bluetooth identity verification is passed, and the mobile phone is in any one of 1 / 2 / 3 / 6 area, or receiving Bluetooth operation control instruction. At this time, the BLE system enters the normal working mode.

[0089] If the condition!A||!L (i.e. first return condition) is met, i.e. pairing is not successful, or Bluetooth identity verification is not passed, the Bluetooth module returns to the first pre-working mode.

[0090] When the BLE system is in the sleep waiting mode, if the condition E||(N&S) (i.e., the second return condition) is met, i.e., the CAN NM is in the request state, or the Bluetooth is woken up and is not in the node mode, the BLE system enters the first pre-working mode. When the condition A&L&(Q&S||G) (i.e., the second normal working condition) is met, i.e., the pairing is successful, and the Bluetooth identity authentication is passed, and the positioning of the mobile phone in any one of 1 / 2 / 3 / 6 areas changes, and the mobile phone is not in the node mode, or the pairing is successful, and the Bluetooth identity authentication is passed, and the positioning of the mobile phone in any one of 1 / 2 / 3 / 6 areas changes, and a Bluetooth operation control instruction is received, the BLE system enters the normal working mode.

[0091] If the low-power consumption condition is met, i.e., P (a BLE sleep response is received or 10 s is timed out), the BLE system enters the low-power consumption condition.

[0092] In the embodiment of the application, the Bluetooth module is switched between different working modes through software adjustment without changing the whole vehicle architecture, so that the whole vehicle power consumption is reduced, and the vehicle reliability is improved. Relying on the normal use habit of the vehicle owner, the product is optimized as much as possible under the premise of meeting the driving demand of the vehicle owner through software adjustment.

[0093] In addition, the embodiment of the application further provides a mode switching device. Referring to Figure 5 A mode switching device 500 provided by the embodiment of the application is shown in FIG. 5. The device 500 includes:

[0094] A response unit 501 is configured to acquire a current working condition and a first working mode in response to the connection distance between the mobile phone and the vehicle being lower than a preset threshold value; the first working mode is used to indicate the current working mode of the Bluetooth BLE system.

The response unit 501 is configured to acquire a current working condition and a first working mode when a distance between the mobile phone and the vehicle is less than a preset threshold.
