DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] In view of the above problems, the present invention provides a method for updating the time of a car, so that the on-board system of the car can achieve stable and reliable time updating. Figure 1 FIG. 1 is one of the flow charts of the time updating method of the automobile provided by the present invention, such as Figure 1 As shown, the method includes: Step 110, when the calling interval is not less than the updating interval threshold, obtaining the current round positioning position; Step 120, determining a position change distance based on the current round positioning position and the previous round positioning position, and comparing the position change distance and the position radius to obtain a positioning drift result; Step 130: automatically updating the current time of the vehicle based on the positioning drift result.

[0020] Here, the call interval duration refers to the interval time between the current time and the last call to the time update process during the driving process of the car. Here, the update interval threshold refers to the interval time between two adjacent calls to the time update process during the driving process of the car, which can be preset and can be adjusted according to the actual driving conditions. For example, the update interval threshold can be 1 minute. Here, the current round positioning position refers to the car positioning information obtained when the time update process is called for the current time, which can be expressed in longitude and latitude. Therefore, the last round positioning position refers to the car positioning information obtained when the time update process was called for the last time.

[0021] In addition, the location radius here refers to a preset length with the current vehicle as the center. The location radius here can be 500 meters or 1000 meters.

[0022] Specifically, the current round positioning position of the car can be obtained by obtaining the call interval duration, and when the call interval duration is not less than the update interval threshold. For example, satellite positioning data, such as GPS positioning data, can be obtained. Then, the position change distance can be calculated by the current round positioning position and the previous round positioning position. For example, the longitude and latitude change distance can be calculated.

[0023] Further, the position change distance is compared with the position radius to obtain a positioning drift result. Specifically, when the position change distance exceeds the position radius, the positioning drift result of the car is that there is drift. When the position change distance does not exceed the position radius, the positioning drift result of the car is that there is no drift.

[0024] It is understandable that the position change distance can be reflected in the size of the position change of the car in the satellite positioning data within the call interval, and the position radius can be reflected in the size of the theoretical position change of the car within the call interval. Therefore, when the position change of the car in the satellite positioning data is greater than the size of the theoretical position change, it means that the current round positioning position of the car may drift, that is, the longitude and latitude information of the current round positioning position may be inaccurate. For example, the area corresponding to the time zone A of the actual car, due to the existence of drift, the current round positioning position obtained is the area corresponding to the time zone B. If the time is updated directly based on the current round positioning position at this time, it will cause inaccurate time.

[0025] Finally, the current time of the vehicle multimedia system can be automatically updated based on the positioning drift result. Specifically, when the positioning drift result indicates that there is drift, the current time of the vehicle is not updated; when the positioning drift result indicates that there is no drift, the current time of the vehicle is updated based on the time zone corresponding to the current round of positioning position.

[0026] It should be noted that when the positioning drift result shows that there is drift, if the current time of the car is updated, and there may also be positioning drift in the next round of automatic time update, the time zone will jump back to the original time zone, and then cause the time to jump back and forth between multiple time zones.

[0027] Therefore, the method provided by the embodiment of the present invention determines the position change distance through the current round positioning position and the previous round positioning position, compares the position change distance and the position radius, and obtains the positioning drift result, so as to automatically update the current time of the car based on the positioning drift result, thereby realizing reliable and stable automatic time update and avoiding the situation of chaotic car time jumps.

[0028] Based on any of the above embodiments, in step 120, comparing the position change distance and the position radius to obtain a positioning drift result includes: When the position change distance exceeds the position radius, the positioning drift result is obtained as drift exists; When the position change distance does not exceed the position radius, the positioning drift result is obtained as no drift exists.

[0029] Specifically, when the position change distance exceeds the position radius, the positioning drift result is obtained as drift exists; when the position change distance does not exceed the position radius, the positioning drift result is obtained as drift does not exist. It should be noted that the position radius can be modified based on the actual situation, and can be comprehensively adjusted based on the update interval threshold and the speed limit of the car's driving area. In this way, the positioning drift result obtained by judgment can be made more accurate, thereby making the current time of the car more stable and avoiding the situation of time jump confusion.

[0030] Based on any of the above embodiments, step 130 includes: When the positioning drift result is that there is no drift, automatically updating the current time of the vehicle based on the current round positioning position; When the positioning drift result indicates that there is drift, the current time is obtained based on the historical time.

[0031] Specifically, when the positioning drift result is that there is no drift, the current time of the car is automatically updated based on the current round positioning position. For example, the time zone corresponding to the current location of the car can be obtained by accessing the time zone library, and the time of the car can be adjusted according to the obtained time zone to automatically update the current time of the car. In addition, when the positioning drift result is that there is drift, the current time is updated based on the time zone information of the historical time, that is, the time zone information of the car is kept unchanged, and the time is automatically moved according to the historical time.

[0032] Based on any of the above embodiments, the method of automatically updating the current time of the vehicle based on the current round positioning position includes: The target time information corresponding to the current round positioning position is selected from the time zone library to automatically update the current time of the car based on the target time information.

[0033] Here, the time zone library may be an online time zone library, which may contain time zone information corresponding to each area divided by longitude and latitude.

[0034] Specifically, the target time information corresponding to the current round positioning position can be selected from the time zone library by accessing the time zone library. Then, the current time of the car is automatically updated according to the time zone reflected by the target time information, and the updated time is the time zone standard that meets the driving area of ​​the car.

[0035] Based on any of the above embodiments, step 110 includes: When the calling interval duration is not less than the updating interval threshold, or when the vehicle is powered on for the first time, the current round positioning position is obtained.

[0036] Here, when the car is powered on for the first time, it may be when the car is powered on, for example, when a start button of the car is pressed.

[0037] Specifically, when the car is driving or preparing to drive, the current time of the car needs to be automatically updated. Therefore, when the call interval is not less than the update interval threshold, or when the car is powered on for the first time, the current round positioning position is obtained to perform the subsequent automatic update process. It should be noted that when the car is activated for the first time, after the car is connected to the network, the current time of the car can be automatically updated based on the current round positioning position of the car.

[0038] It can be understood that the accuracy of the time of the automobile during the entire process of preparing for driving and driving can be guaranteed thereby.

[0039] Based on any of the above embodiments, the current time at least includes time zone information and summer and winter time information.

[0040] It is understandable that due to the different longitudes of various countries and regions, some regions contain multiple time zones, or there is winter and summer time information switching. It is understandable that in order to make the on-board time of the car consistent with the local time, it is necessary to automatically update the current time of the car based on the time zone and winter and summer time information of the area where the car is located, so as to ensure that the time of the car is consistent with the time of the area where the car is located, which is conducive to improving the driving experience of the driver.

[0041] Based on any of the above implementations, Figure 2FIG. 2 is a flow chart of the method for updating the time of a vehicle provided by the present invention. Figure 2 As shown, the method includes: It should be noted that the time when the car leaves the factory is the factory default time, such as 0:0:00 on January 1, 1970. First, the car leaves the factory, and then obtains the network. The network of T-BOX (Telematics BOX, car networking system) can be obtained through the TCP (Transmission Control Protocol) protocol. At this time, if the network is not obtained, the default factory time will be automatically set to update the current time of the car. If the network is detected later, or the network is successfully obtained after leaving the factory, the key, location radius and call interval duration can be obtained. For example, the TSP (Telematics Service Provider, car remote service provider) can be accessed through the Token interface to obtain the key, location radius and call interval duration. If the acquisition fails, the current time zone of the car will not be updated.

[0042] During the use of the vehicle, determine whether the call interval duration reaches the update interval threshold, or whether the car is powered on for the first time. If the call interval duration does not reach the update interval threshold, or the car is not powered on for the first time, the current time zone of the car will not be updated; if the call interval duration reaches the update interval threshold, or the car is powered on for the first time, determine whether the position change distance exceeds the position radius. If the position change distance exceeds the position radius, the current time zone of the car will not be updated. If the position change distance does not exceed the position radius, determine the time zone, winter and summer time information and other time information corresponding to the current round of positioning from the time zone library to automatically update the current time of the car.
