DETAILED DESCRIPTION

[0038] The embodiments of the present application are described in detail below with reference to the accompanying drawings. The embodiments described below are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0039] The method, device, vehicle and storage medium for reminding of a mobile terminal left in a vehicle according to the embodiments of the present application are described below with reference to the accompanying drawings. In view of the technical problems in the related art mentioned above, the reminding based on sensor data is prone to be triggered by the large action amplitude of the carrier, the reminding function of the mobile terminal dedicated rack is single, and the normal use of the mobile terminal is affected, and the convenience is low, etc. The present application provides a method for reminding of a mobile terminal left in a vehicle. In the method, whether the mobile terminal is left outside the vehicle can be determined by comparing the displacement path of the mobile terminal and the actual movement path of the vehicle, and when it is determined that the mobile terminal is left outside the vehicle, a search prompt is generated according to the displacement path of the mobile terminal, so as to facilitate the recovery of the mobile terminal, avoid the triggering by the large action amplitude of the carrier, and the mobile terminal does not need to be placed in a fixed position, thereby improving the user experience. Thus, the technical problems in the related art, such as the reminding based on sensor data being prone to be triggered by the large action amplitude of the carrier, the reminding function of the mobile terminal dedicated rack being single, the normal use of the mobile terminal being affected, and the convenience being low, etc. are solved.

[0040] Specifically, Figure 1 A flowchart of a method for reminding of a mobile terminal left in a vehicle according to an embodiment of the present application.

[0041] As Figure 1 shown, the method for reminding of a mobile terminal left in a vehicle includes the following steps:

[0042] In step S101, the displacement path of the mobile terminal is acquired.

[0043] In actual implementation, the embodiment of the present application can record the displacement path of the mobile terminal through an acceleration sensor of the mobile terminal, so as to transmit the displacement path to the vehicle end.

[0044] The mobile terminal can be a smart device such as a vehicle smart key, a mobile phone, a tablet computer, a smart watch, etc.

[0045] Optionally, in an embodiment of the present application, the displacement path of the mobile terminal is acquired, including: judging whether the mobile terminal satisfies a preset motion state judgment condition; if the mobile terminal satisfies the preset motion state judgment condition, receiving a device motion state signal of the mobile terminal; and calculating the displacement path based on the device motion state signal.

[0046] Specifically, the embodiment of the present application can pre-set a signal sampling frequency in the mobile terminal, so as to collect an acceleration signal at the moment when the mobile terminal changes from a stationary state to a moving state, that is, at the moment when the mobile terminal satisfies the preset motion state judgment condition, the device motion state signal is obtained, and the device motion state signal is sent to the vehicle end connected with the mobile terminal, wherein the connection mode can be Bluetooth connection, WIFI connection or data line connection, etc., so that the embodiment of the present application can calculate the displacement path of the mobile terminal after receiving the device motion signal.

[0047] Optionally, in an embodiment of the present application, the displacement path is calculated based on the device motion state signal, including: acquiring an acceleration value in each motion direction according to the device motion state signal; and based on the acceleration value in each motion direction, using a preset displacement algorithm model to acquire a cumulative displacement in a preset time length, to generate the displacement path.

[0048] As a possible implementation manner, the embodiment of the present application can obtain the acceleration values of the mobile terminal in X, Y and Z directions based on the device motion state signal, and when the acceleration value detected in any direction is ≤ threshold value N, it can be judged that the mobile terminal is in a stationary state, and when the acceleration value detected in any direction is > threshold value N, it can be judged that the mobile terminal is in a moving state.

[0049] The value of the threshold value N can be adjusted and calibrated according to actual conditions, and the embodiment of the present application can adjust the sensitivity of the mobile terminal state judgment through the N value.

[0050] The embodiment of the present application can construct an algorithm model of X=V0t+0.5at2, wherein a is a sampling signal value (i.e. acceleration value) in X\Y\Z direction, t is the sampling signal duration, and V0 is the initial speed of the smart device. The embodiment of the present application can superimpose the vectors in the infinite directions of the smart device movement, thereby obtaining the cumulative displacement X m =X1+X2+X3+…+X n The displacement path of the smart device is calculated and drawn.

[0051] Optionally, in one embodiment of the present application, before the acceleration value in each movement direction is obtained according to the device movement state signal, the embodiment further comprises: judging whether the duration of the device movement state signal exceeds a preset time; and if the duration does not exceed the preset time, setting the signal value of the device movement state signal to zero.

[0052] In some embodiments, the embodiment of the present application can judge whether the duration of the device movement state signal exceeds a preset time (e.g. 1s) when continuously obtaining the acceleration value, i.e. whether the duration of the signal value in X\Y\Z direction exceeds the preset time, and set the signal value of the device movement state signal to zero when the duration does not exceed the preset time, thereby filtering the signal.

[0053] In step S102, the displacement path is compared with the actual movement path of the vehicle to obtain the matching threshold of the displacement path and the actual movement path.

[0054] In actual execution process, the embodiment of the present application can obtain the positioning signal of the vehicle end, and memorize the driving path in the map database of the vehicle end to obtain the actual movement path of the vehicle, so as to compare the displacement path of the mobile terminal with the actual movement path of the vehicle to obtain the matching threshold of the displacement path and the actual movement path.

[0055] In step S103, when the matching threshold is less than a preset first coincidence threshold, it is determined that the mobile terminal is lost, the user is reminded of the device loss, and a search prompt is generated according to the displacement path.

[0056] It can be understood that when the positioning signal of the vehicle end is obtained, due to positioning drift, algorithm error, etc., the actual movement path of the vehicle obtained by the embodiment of the present application does not completely match the driving path of the vehicle, therefore, the preset coincidence threshold of the embodiment of the present application can be set according to the actual situation of the vehicle by the person skilled in the art, when the matching threshold is less than the first coincidence threshold, such as less than 5%, the embodiment of the present application can determine that the mobile terminal is not in the vehicle, and then remind the user of the device loss and generate a search prompt according to the displacement path of the mobile terminal.

[0057] Optionally, in an embodiment of the present application, the finding prompt is generated according to the displacement path, comprising: obtaining current first positioning information of the mobile terminal; obtaining current second positioning information of the vehicle; inputting the current first positioning information and the current second positioning information into a preset positioning algorithm model to output a distance between the mobile terminal and the vehicle; and generating a finding path of the mobile terminal based on the distance.

[0058] In some embodiments, the embodiment of the present application can construct a positioning algorithm model to calculate the distance between two GPS coordinate points of the vehicle. In the main function, two GPS coordinate points are defined to represent the initial position and the coordinate position of the displacement within T time, respectively. The distance between the two points is calculated by calling the calculate_distance function and outputting the result D, i.e., outputting the distance between the mobile terminal and the vehicle, so as to generate the finding path of the mobile terminal based on the distance.

[0059] Optionally, in an embodiment of the present application, after obtaining the matching threshold of the displacement path and the actual moving path, the method further comprises: when the matching threshold is greater than or equal to a preset second coincidence threshold, determining that the mobile terminal is in the vehicle, and prohibiting the vehicle from generating the finding prompt.

[0060] In actual execution process, when the matching threshold is greater than or equal to a preset second coincidence threshold, such as 90%, the embodiment of the present application can determine that the mobile terminal is in the vehicle, so that no prompt is needed, the vehicle is prohibited from generating the finding prompt, and false alarm is avoided.

[0061] As a possible implementation manner, the embodiment of the present application can use at least one acoustic reminding device of the vehicle, such as a buzzer, a horn, etc., to remind the device loss by means of alarm sound prompt or voice prompt; the embodiment of the present application can also use at least one optical reminding device of the vehicle, such as an instrument panel indicator light, a center console text reminder, etc., to remind the device loss; and the embodiment of the present application can also use at least one vibration reminding device, such as a steering wheel vibration, a smart cockpit vibration, etc., to remind the device loss.

[0062] While reminding the device loss, the embodiment of the present application can also display the displacement path of the mobile device and the finding planning path obtained from the current position of the vehicle and the actual position of the mobile terminal through the display end of the vehicle, so as to facilitate the user to find the mobile terminal.

[0063] In addition, the embodiment of the present application can also call the mobile terminal through the vehicle end, so that the mobile terminal can communicate with the user after being picked up by others.

[0064] In combination withFigure 2 and Figure 3 The working principle of the lost reminding method of the in-vehicle mobile terminal according to an embodiment of the present application is described in one embodiment as shown in the following.

[0065] For example, the embodiment of the present application can implement the lost reminding method of the in-vehicle mobile terminal by using a framework as shown in the following. Figure 2

[0066] The framework as shown in the following can include two parts of a mobile terminal, i.e., a smart device, and a vehicle terminal. Figure 2

[0067] The smart device can include an acceleration sensor A1 and a communication transmission module A2.

[0068] The vehicle terminal can include a communication transmission module B1, a positioning sensor B2, a central processing unit B3, a display unit B4, and a map database B5.

[0069] The acceleration sensor A1 can acquire a device motion state signal of the smart device, which is used for calculating a moving path.

[0070] The communication transmission module A2 of the smart device and the communication transmission module B1 of the vehicle terminal can establish a connection between the smart device and the vehicle, providing a channel for signal transmission.

[0071] The positioning sensor B2 is used for acquiring a terminal positioning signal and memorizing a path.

[0072] The central processing unit B3 is responsible for completing calculation, logical judgment, and the like.

[0073] The display unit B4 provides interface display and information presentation for a user.

[0074] The map database B5 is used for path information basic comparison, facilitating accurate reference.

[0075] Based on the above framework, the embodiment of the present application can include the following steps as shown in the following. Figure 3

[0076] Step S1: After the vehicle is started, initialization is started.

[0077] Step S2: The vehicle terminal starts receiving the acceleration signal sent by the smart device. The smart device can be preset with a signal sampling frequency, and the system starts to collect the acceleration signal and starts displacement path calculation based on the acceleration signal at the moment when the state changes from static to moving.

[0078] ​​​Step S3: the acceleration sensor acquires the state information of the current smart device, detects the X\Y\Z direction acceleration value, and detects the acceleration in any direction > threshold value N, enters step S4 for path calculation, and the N value of the X\Y\Z direction can be adjusted and calibrated according to the actual situation, and the sensitivity of the system can be adjusted through the N value.

[0079] Step S5: the vehicle end memorizes the driving path in the map database B5 based on the positioning signal.

[0080] Step S6: the central computing unit B3 is used to calculate the displacement path of the smart device, specifically, an algorithm model of X = V0t + 0.5at2 is constructed, wherein a is the sampling signal value (i.e. acceleration value) in the X\Y\Z direction, t is the sampling signal duration, and V0 is the initial speed of the smart device. The embodiment of the application can superimpose the infinite directions of the smart device movement into a vector, so as to obtain the cumulative displacement X = X1+X2+X3+…+Xn. m n The displacement path of the smart device is calculated and drawn.

[0081] Step S7: in the central computing unit B3, the actual path of the vehicle and the displacement path of the smart device are compared, considering the positioning drift and algorithm error, if the preset coincidence threshold is ≥ 90%, step S8 is entered, the smart device is considered to be in the vehicle, and the vehicle is in a safe state, the vehicle does not give any reminder, and the process is terminated. If the preset coincidence threshold is < 5%, step S9 is entered, and the smart device is not in the vehicle, and movement occurs.

[0082] Step S8: judging that the smart device is in the vehicle.

[0083] Step S9: judging that the smart device is not in the vehicle.

[0084] Step S10: the path value is converted into a navigation signal value by the central computing unit B3, the current smart device position is displayed on the display unit B4, and a positioning algorithm model is constructed, which can calculate the distance between two GPS coordinate points of the vehicle. The calculate_distance function uses the Haversine formula to calculate the great circle distance between two GPS coordinate points, and the return value is in meters. In the main function, two GPS coordinate points are defined to represent the initial position and the coordinate position of the displacement within T time, the distance between the two points is calculated by calling the calculate_distance function, and the result D is output.

[0085] Step S11: generating navigation information.

[0086] Step S12: controlling the vehicle to reach the vicinity of the smart device.

[0087] ​According to the method for reminding a mobile terminal left in a vehicle proposed in the embodiments of the present application, whether the mobile terminal is left outside the vehicle can be determined by comparing the displacement path of the mobile terminal and the actual moving path of the vehicle, and when it is determined that the mobile terminal is left outside the vehicle, a searching prompt is generated according to the displacement path of the mobile terminal, so as to facilitate the searching of the mobile terminal and avoid the false triggering due to the large action amplitude of the carrier, and the mobile terminal does not need to be placed in a fixed position, thereby improving the user experience. Thus, the technical problems in the prior art that the reminder based on the sensor data is prone to false triggering due to the large action amplitude of the carrier, the reminder function of the special mobile terminal rack is single, the normal use of the mobile terminal is affected, and the convenience is low are solved.
