[0002] With the improvement of the level of social intelligence, people are becoming more and more demanding on the intelligence of cars. From traditional mechanical physical keys to today's physical car keys that integrate low-power Bluetooth and UWB technology, physical car keys are moving towards a more convenient and intelligent direction.

[0003] However, with the integration of new technologies, the power consumption brought by low-power Bluetooth and UWB in physical car keys is very large, and the power consumption of UWB is several times that of low-power Bluetooth. In addition, the physical car keys are powered by button batteries. If Bluetooth and UWB are turned on for a long time, the life of the button batteries will be greatly shortened, resulting in the need to frequently replace the batteries, affecting the user experience.

[0004] Therefore, how to reduce the power consumption of physical car keys is an urgent problem that needs to be solved. Summary of the invention

[0080] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0081] In this application, relational terms such as first and second, etc. are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the statement "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0082] The present application embodiment provides a method for processing key power consumption, such as Figure 1 As shown, the specific steps include:

[0083] S101. When it is detected that the physical key is powered on, the current state of the physical key is switched to a wake-up state.

[0084] It is understandable that when it is detected that the key is inserted or touches the power source, that is, when the key is powered on, the key state will become awake so that it can subsequently start communicating with other devices or perform specific operations, thereby ensuring that the key can respond immediately when needed and minimize energy consumption when not in use.

[0085] Optionally, once it detects that the key is powered on, it can send a specific wake-up signal to the vehicle or establish a connection to start authentication, unlocking the vehicle, etc. This approach ensures that the physical key can respond quickly and communicate with the vehicle when needed while maintaining low power consumption.

[0086] S102: Detect whether the physical key is connected to the Bluetooth of the vehicle within a first preset time period.

[0087] It should be noted that in the embodiment of the present application, when the state of the physical key is the awake state, it is necessary to combine the connection between the key and Bluetooth to understand the user's usage scenario, and then switch the key to different working states, so that the purpose of low power consumption can be achieved in different working states, and by detecting the Bluetooth connection, the vehicle system can determine whether there is an authorized physical key nearby, and can allow the use of specific functions under certain conditions, such as unlocking the door, starting the engine, etc. Therefore, when the state of the physical key is the awake state, it is necessary to immediately detect whether the physical key is connected to the vehicle's Bluetooth within the first preset time period. If the physical key is not connected to the vehicle's Bluetooth within the first preset time period, it means that the owner currently does not have a scenario to use the physical key, so step S103 is executed.

[0088] Optionally, the first preset time period is 30 seconds, and of course it can also be other time thresholds, which can be set specifically according to requirements.

[0089] S103: Switch the wake-up state of the physical key to the sleep state.

[0090] Specifically, when the physical key is not connected to the vehicle's Bluetooth within the first preset time period, it means that the owner does not need to use the vehicle at present. In order to reduce the power consumption of the physical key, it is necessary to switch the wake-up state of the physical key to the sleep state, which can also reduce the use of the battery and thus increase the service life of the key battery.

[0091] It should be noted that when the physical key is in sleep mode, the physical key's Bluetooth broadcast and other functions such as UWB are turned off. At this time, the vehicle task is suspended and only the button and motion sensor functions are retained.

[0092] S104: Determine, by means of a motion sensor, whether the current posture of the physical key is moving.

[0093] It should be noted that when the physical key is in sleep mode, in order to ensure timely response and communication with the vehicle, the motion sensor needs to determine whether the current posture of the physical key is moving, which helps to improve the user experience and ensure that the vehicle can start or perform other operations normally when the physical key is carried. For example, if the owner puts the physical key in his pocket or holds it in his hand, it means that the current posture of the physical key is moving.

[0094] Therefore, if the current posture of the physical key moves, it means that the owner may need to use the car, so step S105 is executed. Optionally, if the current posture of the physical key does not move, it means that the owner still does not need to use the car, so the physical key remains in a dormant state.

[0095] Optionally, in another embodiment of the present application, a specific implementation of step S104 includes the following steps:

[0096] Get the corresponding acceleration values ​​in the three-dimensional direction that have been pre-collected when the physical key is in the awake state.

[0097] It should be noted that in order to ensure that the physical key can be promptly informed of whether it moves when it is in the sleep state, it is necessary to use the motion sensor module to periodically detect the acceleration value of the sensor physical key on the three mutually perpendicular axes xyz (that is, three-dimensional directions) with the surface plane of the sensor chip as the xoy plane when the physical key is in the sleep state, that is, when it is awakened, so as to determine whether the physical key has moved.

[0098] In the sleep state, the motion sensor periodically collects the current acceleration value corresponding to the physical key in the three-dimensional direction, and calculates the difference between the corresponding acceleration in each direction and the current acceleration.

[0099] It is understandable that in order to determine whether the physical key has moved in the sleep state, it is also necessary to periodically collect the acceleration values ​​of the physical key on the three mutually perpendicular axes xyz (that is, three-dimensional directions) through the motion sensor in the sleep state, and calculate the difference between the corresponding acceleration in each direction and the current acceleration. The difference is used to determine whether the physical key has moved.

[0100] Compare whether the difference in any direction is greater than a preset threshold within a preset time period.

[0101] It should be noted that in the embodiment of the present application, in order to prevent the physical key from being accidentally touched and moving, it is necessary to compare whether the difference in any direction is greater than a preset threshold within a preset time period. If the difference in any direction is greater than the preset threshold within the preset time period, it is more certain that the current posture of the physical key has moved. If the difference in any direction is less than the preset threshold within the preset time period, it can be basically determined that the current posture of the physical key has not moved.

[0102] or,

[0103] When the motion sensor detects that a button on the physical key is triggered, it is determined that the current posture of the physical key moves.

[0104] It should be noted that when a button on the physical key is triggered by the car owner, it means that the car owner may use the physical key to perform relevant operations on the vehicle at this time, such as starting the engine or unlocking the door. Therefore, it can also be determined that the current posture of the physical key is moving. Therefore, when the motion sensor detects that the button on the physical key is triggered, it is determined that the current posture of the physical key is moving.

[0105] S105: Switch the sleep state of the physical key to a standby state, and in the standby state, detect whether the physical key is connected to the vehicle via Bluetooth within a first preset time period.

[0106] It should be noted that when the current posture of the physical key moves, in order to prevent the physical key from being accidentally touched, thereby detecting that the physical key has moved, the sleep state of the physical key can be switched to the waiting state first, and then in the embodiment of the present application, in order to further know whether the physical key has actually moved or been accidentally touched, the system can confirm through Bluetooth, that is, detect whether the physical key is connected to the vehicle's Bluetooth within a first preset time period. If the physical key is connected to the vehicle's Bluetooth within the first preset time period, the owner can use the physical key to communicate with the vehicle and determine that the functions of the physical key still need to be used, so step S106 is executed at this time.

[0107] Optionally, if the physical key is not connected to the vehicle's Bluetooth within a first preset time period, the acceleration value of the physical key in the current xyz direction is recorded by a motion sensor, and then the waiting state of the physical key is switched to a sleeping state.

[0108] S106: Switch the physical key's standby state to a moving state, and detect whether the UWB ranging function of the physical key is turned on.

[0109] It should be noted that when the physical key is connected to the vehicle's Bluetooth within the first preset time period, it means that the car owner needs to use the car at this time and needs to use the button function on the physical key. Therefore, it is necessary to switch the physical key's standby state to the motion state. However, since the physical key needs to be at a certain distance from the vehicle, the function on the button can be sensed by the vehicle, thereby triggering the vehicle to perform corresponding actions. Therefore, it is necessary to locate the vehicle's position information, which can be achieved through the UWB ranging function on the physical key. However, since the UWB ranging function consumes a lot of power, the physical key must meet certain requirements before the UWB ranging function can be turned on. Therefore, after switching the physical key's standby state to the motion state, it is necessary to determine whether to turn on the UWB ranging function of the physical key. If the UWB ranging function of the physical key is turned on, it means that the physical key has met the requirements for turning on the UWB ranging function. Therefore, step S107 is executed at this time.

[0110] Optionally, if the UWB ranging function of the physical key is not enabled, it means that the physical key does not meet the requirements for enabling the UWB ranging function, and therefore further testing is required.

[0111] Optionally, in another embodiment of the present application, a specific implementation of step S106 is as follows: Figure 2 As shown, the following steps are included:

[0112] S201. Measure the distance between the physical key and the vehicle through Bluetooth technology.

[0113] It should be noted that since the UWB ranging function of the physical key consumes too much power, when the physical key is in motion, the car and the physical key are connected via Bluetooth. The two can first measure the distance via Bluetooth, thereby avoiding turning on the UWB ranging function for ranging at the beginning, which can effectively reduce the power consumption of the car's physical key.

[0114] S202: Determine whether the distance between the physical key and the vehicle is less than a preset distance.

[0115] Specifically, since the UWB ranging accuracy is much higher than the Bluetooth RSSI ranging, in order to further accurately measure the vehicle's location information, the key's UWB can be turned on for more accurate ranging after the distance measured by the Bluetooth technology is less than a certain distance. Therefore, it is necessary to further determine whether the distance between the physical key and the vehicle is less than the preset distance. If the distance between the physical key and the vehicle is less than the preset distance, it means that the physical key's UWB ranging function will be turned on for ranging, so step S203 is executed.

[0116] Optionally, if the distance between the physical key and the vehicle is greater than a preset distance, it means that the UWB ranging function of the physical key cannot be activated to avoid consuming the power consumption of the physical key.

[0117] S203: Determine whether to enable the UWB ranging function of the physical key.

[0118] Specifically, when the distance between the physical key and the vehicle is less than the preset distance, the UWB ranging function of the physical key needs to be enabled. For details, please refer to Figure 3 The content shown, Figure 3 Slave modules are installed at the four corners of the CRRC train, supporting ble (RSSI ranging) and UWB ranging. The one in the middle is the master module. After obtaining the distance values ​​between the four nodes in the car and the physical key, the location information of the physical key can be obtained by solving the positioning equation.

[0119] S107: After the USB ranging function is turned on for longer than a preset time, the UWB ranging function is turned off.

[0120] It should be emphasized that after turning on the UWB ranging function of the physical key, it is necessary to turn off the USB ranging function after using it for a certain period of time, so as to effectively reduce the power consumption of the physical key. Therefore, it is necessary to obtain the turning-on time of the USB ranging function, and then turn off the UWB ranging function after the turning-on time of the USB ranging function is greater than the preset time.

[0121] Optionally, the preset time is 2 minutes, and of course it can also be other time thresholds, which can be specifically set according to needs.

[0122] Optionally, UWB can also be turned off due to actual working conditions. For example, after the car starts, the main module of the vehicle will notify the physical key to turn off UWB.

[0123] Optionally, the physical key may be automatically disconnected from the vehicle's Bluetooth. In order to switch the state of the physical key in a timely manner to reduce power consumption, in another embodiment of the present application, the Bluetooth connection status is also detected. Figure 4 As shown, another embodiment of the present application provides a method for detecting disconnection of a physical key, comprising the following steps:

[0124] S401, detecting whether the current physical key is disconnected from the vehicle's Bluetooth.

[0125] It should be noted that when the physical key is in motion, the physical key will automatically disconnect from the vehicle's Bluetooth. Therefore, it is necessary to periodically check whether the current physical key is disconnected from the vehicle's Bluetooth. If the current physical key is disconnected from the vehicle's Bluetooth, it is necessary to switch the current state of the physical key in time to avoid turning on the UWB ranging function of the physical key again. Therefore, step S402 is executed at this time.

[0126] S402: Collect the acceleration values ​​corresponding to the current physical key in three-dimensional directions through a motion sensor, and switch the motion state of the physical key to a sleep state.

[0127] It should be noted that when the current physical key is disconnected from the vehicle's Bluetooth, it is also necessary to collect the acceleration values ​​corresponding to the current physical key in the three-dimensional direction through the motion sensor, and switch the motion state of the physical key to the sleep state, so as to subsequently determine whether the physical key moves again when the physical key is in the sleep state.

[0128] Optionally, when it is detected that the physical key is powered on, the current state of the physical key is switched to the awake state. There is also a situation where the physical key is immediately connected to the Bluetooth of the vehicle, so after executing step S102, optionally, as Figure 5 As shown, another embodiment of the present application provides another method for processing key power consumption, comprising the following steps:

[0129] S501. If the physical key is connected to the vehicle via Bluetooth within a first preset time period, the distance between the physical key and the vehicle is measured using Bluetooth technology.

[0130] Specifically, after the physical key is powered on, the current state of the physical key is switched to the awake state, and if the physical key is connected to the vehicle's Bluetooth within a first preset time period, it means that the owner is holding the key close to the door, and the key itself can sense the vehicle within a certain distance, thereby automatically unlocking the door. Therefore, it is necessary to measure the distance between the physical key and the vehicle through Bluetooth technology.

[0131] S502: Determine whether the distance between the physical key and the vehicle is less than a preset distance.

[0132] It should be noted that the specific implementation of step S502 may refer to step S202 in the above method embodiment, and will not be described in detail here.

[0133] It should also be noted that if the distance between the physical key and the vehicle is less than the preset distance, step S503 is executed.

[0134] S503, turning on the UWB ranging function of the physical key, and turning off the UWB ranging function after the USB ranging function is turned on for longer than a preset time.

[0135] It should be noted that the specific implementation of step S503 may refer to step S107 in the above method embodiment, and will not be described in detail here.

[0136] S504: After turning off the UWB ranging function, when it is detected that the physical key is disconnected from the vehicle's Bluetooth, the corresponding acceleration value of the physical key in the three-dimensional direction is collected through the motion sensor, and the motion state of the physical key is switched to the sleep state.

[0137] It should be noted that the specific implementation of step S504 may refer to step S402 in the above method embodiment, and will not be described in detail here.

[0138] S505: Determine whether the current posture of the physical key is moving according to the acceleration values ​​corresponding to the physical key in the three-dimensional directions.

[0139] It should be noted that before the physical key goes to sleep each time, the motion sensor needs to collect the acceleration values ​​gx, gy, gz in the xyz direction (that is, in the three-dimensional direction) for a period of time, and use this acceleration value as the reference value. After the physical key goes to sleep, the motion sensor will periodically collect the acceleration values ​​fx, fy, fz in the xyz direction, and compare fx, fy, fz with gx, gy, gz to determine whether the physical key has moved. That is, when the difference between the acceleration value in any direction and the reference value is greater than a threshold for a certain period of time, it can be considered that the physical key has moved, so step S506 is executed at this time.

[0140] Optionally, if the current posture of the physical key does not move, the acceleration value in the xyz direction continues to be periodically collected through the motion sensor.

[0141] S506: Switch the sleep state of the physical key to the standby state, and detect whether the physical key is connected to the vehicle's Bluetooth.

[0142] Specifically, when the current posture of the physical key moves, it is necessary to promptly switch the sleep state of the physical key to the standby state and turn on the Bluetooth broadcast.

[0143] It should be noted that the specific implementation method of detecting whether the physical key is connected to the vehicle's Bluetooth can be referred to step S105 in the above method embodiment, which will not be repeated here.

[0144] It should also be noted that if it is detected that the physical key is not connected to the vehicle's Bluetooth, step S507 is executed. If the physical key is connected to the vehicle's Bluetooth, step S508 is executed.

[0145] S507: Switch the physical key's standby state back to the sleep state.

[0146] Specifically, before switching back to the sleep state, the acceleration value corresponding to the physical key in the three-dimensional direction is collected through the motion sensor.

[0147] S508: Switch the waiting state of the physical key to the moving state.

[0148] It should be noted that when switching the physical key's standby state to the motion state, it is necessary to return to step S501, that is, measure the distance between the physical key and the vehicle through Bluetooth technology, so as to switch the physical key to different working modes according to the user's usage scenario.
