Description

Time mapping method, system and mobile device applied to internet of vehicles

The invention relates to a time mapping method, system and mobile device, in particular to a time mapping method, system and mobile device applied to the Internet of Vehicles.

Generally speaking, the IoV device mounted on the vehicle can record the driving record of the vehicle. These driving records can be any data related to driving or the state of the vehicle. Common driving records include: total mileage, instantaneous speed, instantaneous acceleration, number of throttles, braking times, acceleration time, battery voltage value, engine speed, steam /Information on locomotive fuel consumption, ground slope, or error codes of electronic control units... Once you have a driving record, you can easily view or manage the driving status and count the user's usage habits.

In order to facilitate the management or analysis of each driving record, each driving record must also be accompanied by the current time of the data in order to effectively analyze the user's usage habits or the vehicle itself. In the existing technology, the IOV device uses an internal timing circuit to attach each driving record to a time stamp generated by the timing circuit. However, because the IoV device may not have a separate communication module to connect to the Internet to obtain the accurate time, when reading the driving records, the sequence and time of each driving record can only be judged from the time stamp Interval, but there is no way to immediately determine the current time of each driving record, so the driving record often cannot effectively count the user's usage habits or driving status, and because the time stamp of the driving record is not the same as the current time format It's so easy to identify, which causes trouble in the inspection of driving records.

Therefore, there is a need for a time mapping method and system applied to the Internet of Vehicles to solve the problems in the prior art.

Please refer to Figures 1 to 3 of the drawings, which show the time mapping method, system and mobile device of the present invention applied to the Internet of Vehicles.

FIG. 1 is a schematic diagram of a connected vehicle system 100 according to an exemplary embodiment of the present invention. In FIG. 1, the connected car system 100 includes a mobile device 102 and a connected car device 106. The mobile device 102 has an application 104 installed therein, and the mobile device 102 can be connected to the Internet 112 to obtain Coordinated Universal Time (UTC). It should be noted that Coordinated Universal Time (UTC) is one of the world standard time formats, but the present invention is not limited to the use of UTC time. The IOV device 106 includes a timer 108 and a management device 110, and the IOV device 106 is disposed on the vehicle 114. The IOV device 106 can obtain various driving records after the vehicle 114 is started, and store the driving records in the management device 110. In addition, the IoV device 106 and the mobile device 102 can be paired and connected with each other to transmit driving records and corresponding time stamps, and time map each driving record. The starting of the vehicle may be an alternative form in which a key is inserted into a key hole of a car or a locomotive to make the electric door open or the engine is started.

FIG. 2 is a schematic diagram of paired connection between the connected vehicle device 106 and the mobile device 102, and time mapping of each driving record. The timer 108 of the IoV device 106 starts counting after each start of the vehicle 114, and when each driving record of the vehicle 114 is generated, the current counted time when the driving record is generated (that is, after the vehicle is started this time to the generation The time of driving records) is appended to each driving record in the form of time stamp. For the convenience of illustration, the time stamp here is in seconds (sec). Subsequently, the management device 110 can store each driving record and its corresponding time stamp.

According to some embodiments, the timer 108 can also use an internal circuit design to separate each driving record of the vehicle 114 each time it is started, and also give a different number to distinguish it, that is, each driving record In addition to the time stamp recorded after starting, a number corresponding to the vehicle starting at different times will be additionally attached, and this number can be carried out in a cyclic numbering manner. For example: when the vehicle 114 is started for the fifth time, the generated driving record will start from 5-1, and the serial numbers are 5-1, 5-2, 5-3... and so on, and these numbers are also The mobile device 102 can be identified. For example, when the mobile device 102 receives a driving record with a number of 3-1, the application program 104 can learn that the driving record is the first driving record for the third start of the vehicle 114. The numbering system shown above is for illustrative purposes only and is not limited to this.

After the vehicle 114 is started for the fifth time, the timer starts counting and the management device 110 also starts to store various driving records; suppose that when the timer 108 counts to the 180th second, the connected vehicle device 106 and the mobile device 102 are paired and connected. Once the IoV device 106 and the mobile device 102 are paired and connected, the IoV device 106 sends the current counted 180 seconds as the current timestamp to the mobile device 102, and notifies the application 104 that the 180th timestamp is the vehicle 114 The current time stamp of the paired connection at the 5th start.

After receiving the time stamp of the 180th second, the mobile device 102 performs time mapping between the 180th second and the current time of the mobile device according to the current UTC time of the mobile device 102. In this example, the UTC time corresponding to the 180th second of the timestamp is 10:23:0 on January 2, 2018. After that, when the mobile device 102 receives the driving record of the vehicle 114 also at the fifth start, it will be based on the 180-second timestamp and its corresponding UTC time on January 2, 2018 at 10:23:0 To obtain the mapping time corresponding to the time stamp of each driving record of the vehicle 114 after this start.

For example, after the mobile device 102 connects with the connected vehicle device 106, when the mobile device 102 receives the driving record numbered 5-1 (20a in FIG. 2), the mobile device 106 confirms the driving number 5-1 The record is the driving record at the start of the current (ie the fifth), and the time stamp of the driving record number 5-1 is 60 seconds. Therefore, the driving record number 5-1 is generated 120 seconds earlier than when pairing and connecting. Since the UTC time corresponding to the pairing connection is 10:23:0 on January 2, 2018, the mapping time of the driving record number 5-1 should be the time of the pairing connection minus 120 seconds, so the application 104 The mapping time showing the driving record number 5-1 will be 10:21:0 on January 2, 2018 (20b in Figure 2).

When the mobile device 102 receives the driving record with the number 5-2, the application 104 confirms that the driving record with the number 5-2 is also the driving record at the time of this (5th) startup, and learns that the driving record number 5 The time stamp of -2 is 720 seconds (20c in Figure 2). Therefore, the driving record number 5-2 is generated 540 seconds later than when pairing and connecting. Since the UTC time corresponding to the pairing connection is 10:23:0 on January 2, 2018, the mapping time of the driving record number 5-2 should be the time of the pairing connection plus 540 seconds, so the application 104 The mapping time for displaying the driving record number 5-2 is 10:32:0 on January 2, 2018 (20d in Figure 2).

In another case, when the mobile device 102 receives the driving record with the number 3-1, the application 104 confirms that the driving record with the number 3-1 does not belong to the action record at the start of this (5th) time; and It is because when the vehicle 114 is started for the third time, since the connected vehicle device 106 and the mobile device 102 are not paired and connected, there is no driving record transmitted to the mobile device 102 at the third start. Since the vehicle 114 does not have a paired connection when it is started for the third time, the application 104 will not receive the time stamp of the third paired connection. In this case, the application 104 of the mobile device 106 will obtain the latest trip record that has been paired and connected before the third activation of all the trip records received by the mobile device 102. In this example, the latest trip record that has been paired and connected before the third start is the trip record number 2-2.

In order for the number 3-1 to correspond to a mapping time, the application 104 obtains the mapping time of the driving record number 2-2 from the mobile device 102, which is 8:19:0 on January 1, 2018 (Figure 2 20e), and learned that the time stamp of driving record number 3-1 is 540 seconds. After that, the application 104 will directly use the time of 8:19:0 on January 1, 2018 as the reference, and directly add it to the timestamp of 540 seconds. Therefore, the mapping time of driving record number 3-1 is 8:28:0 on January 1, 2018.

In summary, as long as the IOV device 106 and the mobile device 102 are paired and connected, the application 104 can time-stamp the paired connection to correspond to the UTC time of the mobile device 102. When the mobile device 102 receives the driving record of the vehicle 114 starting at the same time, the timestamp attached to the driving record will obtain the corresponding mapping time according to the UTC time of the paired connection. Even if the mobile device 102 receives the driving records of the vehicle 114 activated at different times, the application 104 can obtain the mapping times corresponding to the driving records of different activations according to the mapping times of other driving records. Since each driving record is based on the viewpoint of the present invention and the above embodiment, the mapping time can be derived and expressed in UTC time. Therefore, when the application 104 uploads each driving record to the cloud or presents it to the user of the vehicle 114 in the future, the time record of the driving record can be more easily identified, so as to achieve the effect of the present invention.
