Description
Technical Field
The present invention relates to the field of automobiles, and more particularly, to an automobile time system, a time control method thereof, and a control system thereof.
Background
Time occupies a very important position in human life. Under the social environment of rapid development of science and technology and continuous improvement of life quality, the time is also more and more important in daily life of people. The human life can be seen from time to time and plays a great role in life. The reservation and timing functions of household appliances, such as air conditioners, are lacking in the metering of time. It is also desirable that the time be known at any time to plan for the trip.
With the development and progress of science and technology, the functions of the automobile are more and more perfect. Air conditioning and air purification are common functions of automobiles. An instrument panel is arranged on a common automobile so as to facilitate automobile users to know the automobile speed, the automobile energy storage condition, the automobile hand brake state, whether an automobile door is closed or not, the use condition of a safety belt and the like. In addition, the dashboard may also be used to display time information. The time displayed by the instrument panel can generally reflect the time of the air conditioner, the air purifier and other equipment of the automobile.
With the continuous development of internet technology and electronic technology, the internet technology and electronic technology bring great convenience to the life of people and are deeply loved by consumers. With the continuous innovation and progress of the automobile industry, internet automobiles are gradually entering the visual field of vast consumers and are expected by the vast consumers.
Internet automobiles are a derivative of internet + automobiles, but are by no means a simple addition of internet and automobiles. Mutual control and driving can be realized after the internet and the automobile are fused, and mutual convenience is provided. A common Internet automobile is provided with at least one automobile machine. The vehicle machine can provide internet service and various service functions, and music, videos, calls, navigation, social contact and learning are all available. The automobile machine can also control the functional system of the automobile. The intelligent vehicle-mounted intelligent air conditioner and purifier control and reservation of functional systems such as an automobile air conditioner and a purifier through the intelligent vehicle-mounted intelligent.
In many cases, the start of the car body and the start of the car unit are not performed simultaneously, so it is difficult to ensure that the two are synchronized in time. If the time information is acquired from the instrument by the automobile, the automobile cannot acquire the clock source when the instrument fails.
The actuation of many functional systems of a motor vehicle requires a matching time. For example, if the reservation and timing of the air purifier of the automobile are required, it is necessary to match the time provided by the command transmission module thereof with the time of the functional system. In this case, it is very important to achieve time synchronization of each functional system of the vehicle. For example, when a car air conditioning system is controlled by operating a car machine, if the car machine cannot obtain a time parameter or the time parameter provided by the car machine cannot be matched with the time of the car air conditioning system, the car machine may improperly control or fail to control the car air conditioning system.
Sometimes, the consumer may need to set the time by himself, and at this time, if the car machine and the meter are set separately, it is difficult to ensure the time synchronization between the car machine and the meter.

Detailed Description
The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art. The basic principles of the invention, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents, and other technical solutions without departing from the spirit and scope of the invention.
It is understood that the terms "a" and "an" should be interpreted as meaning that a number of one element or element is one in one embodiment, while a number of other elements is one in another embodiment, and the terms "a" and "an" should not be interpreted as limiting the number.
Description of the drawings fig. 1 of the accompanying drawings illustrates a vehicle time system according to a first preferred embodiment of the present invention. As shown in fig. 1, the car time system includes a time setting initiation module 10, a time service module 20, a first clock module 30 and a second clock module 40. According to the first preferred embodiment of the present invention, the first clock module 30 is embodied as a first clock chip RTC (Real-Time clock). The second clock module 40 is embodied as a second clock chip RTC. The first clock module 30 is installed in a vehicle control module M of a vehicle. The second clock module 40 is disposed in an instrument module N of the vehicle.
According to the first preferred embodiment of the present invention, a vehicle of the automobile employs a Linux system. That is to say, a vehicle system S of the vehicle is a Linux system. The Linux system time is adopted for the screen time of the automobile machine. It should be noted that the Linux system time is used for the car screen time of the car, which is only an example and not a limitation of the present invention. According to other embodiments of the present invention, when the car machine of the car adopts other systems, the car machine screen time of the car can also adopt other system times. The present invention is not limited in this respect as long as the object of the present invention can be achieved.
According to the first preferred embodiment of the present invention, the second clock module 40 disposed on the meter module N is used to save the entire vehicle time, so as to solve the problem of the time source when the vehicle is powered on. The first clock module 30 provided to the entire vehicle control system M is used to save GPS time, so that when the meter module N fails, the time of the first clock module 30 is used as the vehicle-on-board power-on time. Therefore, the problem that the vehicle machine does not have a clock source when the instrument module N fails is solved.
Specifically, when the vehicle of the vehicle is started, the vehicle control module M first updates the time of the vehicle system S of the vehicle through the first clock module 30. And after receiving the time of the instrument module N, the whole vehicle control module M synchronizes to synchronize the time of the whole vehicle control module M to the time of the instrument module N, and further synchronize the time of the instrument module N to the vehicle system S of the vehicle. In the above manner, the time of the vehicle system S and the time of the meter module N are kept synchronized, so that the time used by the vehicle system S and the time used by the meter module screen are kept consistent.
The first preferred embodiment of the present invention provides another implementation of time synchronization. When the vehicle of the vehicle is started, the vehicle control module M obtains the time of the second clock module 40 of the meter module N from the second clock module 40 of the meter module N through the first time module 30. The vehicle control module M synchronizes the acquired time of the second clock module 40 of the instrument module N with the time of the vehicle system S through the first time module 40. In this way, the time used by the vehicle machine system S is consistent with the time used by the meter module N. If the vehicle control module M cannot acquire the time of the second clock module 40 set in the instrument module N through the first time module 40, the vehicle control module M synchronizes the time of the first time module 40 with the time of the vehicle system S.
When the time service module 20 is activated, the time service module 20 acquires GPS time and synchronizes the acquired GPS time to the first clock module 30 disposed in the vehicle control system M. If the time is in the starting state automatically and synchronously, the GPS time is set to the vehicle-mounted machine system S through a vehicle-mounted machine system interface. Meanwhile, the time service module 20 sets the GPS time synchronized with the vehicle control system M to the meter module N.
When the user sets the time by himself, the time service module 20 calls the vehicle system interface, and sets the GPS time to the vehicle system S through the vehicle system interface. Meanwhile, the time service module 20 sets the GPS time synchronized with the vehicle control system M to the meter module N.
If the automatic time switch is turned on, the time service module 20 obtains the GPS time, calls the in-vehicle system interface, and sets the obtained GPS time to the in-vehicle system S through the in-vehicle system interface. Meanwhile, the time service module 20 sets the GPS time acquired by the vehicle control system M to the meter module N.
More specifically, as shown in fig. 2, when the vehicle of the vehicle starts, the vehicle of the vehicle obtains time from the vehicle control module M. And the time service module 20 sends the acquired GPS time to the vehicle control module M, so that when the vehicle of the vehicle is started, the vehicle system S synchronizes the GPS time of the vehicle control module M. The instrument module N can send a time signal to the vehicle control module M. If the whole vehicle control module M receives the time signal sent by the instrument module N, the whole vehicle control module M sends the received time signal from the instrument module N to the vehicle machine system S, so that the time of the vehicle machine system S is synchronized with the time of the instrument module N, and the display time of the vehicle machine screen of the automobile is synchronized with the display time of the automobile instrument screen. The time service module 20 can acquire GPS time and synchronize the acquired GPS time to the vehicle control system M. It is worth mentioning that the time service module 20 can continuously acquire GPS time, thereby maintaining the accuracy of the time it provides. If the time automatic synchronization function of the vehicle is in the on state, both the vehicle system S and the vehicle control system M can obtain the GPS time from the time service module 20. The vehicle control system M synchronizes the acquired GPS time to the meter module N. Thus, the time of the vehicle system S and the time of the meter module N are synchronized with the GPS time acquired by the time service module 20, and the vehicle screen display time is synchronized with the vehicle meter screen display time.
As shown in fig. 2, when the user sets the time by himself, the time setting initiation module 10 initiates a time setting instruction to the time service module 20 to provide a user time. The time service module 20 receives the user time provided by the time setting initiation module 10, and synchronizes the user time with the meter module N through the vehicle control system M. Thus, the time of the car machine system S and the time of the meter module N are synchronized with the user time provided by the time setting initiating module 10 and acquired by the time service module 20, and further the car machine screen display time and the car meter screen display time are synchronized with the user time set for the user. That is, the time displayed by the car machine and the time displayed by the car meter are both the time set by the user. Therefore, the automobile machine and the automobile instrument can display time according to the setting of the user. That is to say, the user can change the time that its car machine and instrument show according to own demand to satisfy user's individualized demand.
The time system of the automobile also has the function of automatically setting time so as to keep the time of the automobile accurate. As shown in fig. 2, when the user needs to set or correct the time to GPS time, he can start the function of automatically setting the time through the time setting initiation module 10. When the function of automatically setting time is in the activated state, the time service module 20 can obtain the GPS time and synchronize the GPS time obtained by the time service module to the vehicle control system M and the vehicle system S. The vehicle control system M further synchronizes the GPS time acquired by the vehicle control system M to the meter module N. That is, after the user initiates the instruction for automatically setting the time, the time of the in-vehicle system S and the time of the meter module N are synchronized with the GPS time. So that the time of the car is changed by the user and kept consistent with the GPS time.

If the automatic update switch 7121 is turned off, the GPS time module 7111 obtains the GPS time, and then the GPS time module 7111 performs time synchronization with the clock chip RTC of the vehicle control module M. If the automatic update switch 7121 is turned on, the GPS time module 7111 performs time synchronization with the clock chip RTC of the vehicle control module M after the automatic update command receiving module 7122 receives the automatic update command. Further, the clock chip RTC of the vehicle control module M is used to synchronize the acquired GPS time with the vehicle system S and the meter module N, respectively.
According to the fifth preferred embodiment of the present invention, the instruction for automatically updating the time may be a manual instruction issued by the user, or an automatic instruction automatically issued by the system according to a preset program, for example, an instruction for automatically issuing the automatic update time when the system is powered on, and an instruction for issuing the automatic update time every preset time. As shown in fig. 6, the auto-update command receiving module 7122 includes a manual command receiving module 71221 and an auto command recognition module 71222. The manual instruction receiving module 71221 is used to receive a manual instruction issued by a user. The automatic command recognition module 71222 is used to recognize automatic commands.
As shown in fig. 6, the onboard time module 90 includes a first time signal receiving module 91 and an onboard time presenting module 92. The first time information receiving module 91 is configured to receive a time signal, so that the car time presenting module 92 presents the car time.
The meter time module 80 includes a second time information receiving module 81, a first clock module 82, and a meter time presenting module 83. The second time information receiving module 81 receives a time signal so that the meter time presenting module 83 presents the meter time. The first clock module 82 can measure time, thereby ensuring that the meters of the automobile can normally display time during the period of no time signal input.
As shown in fig. 6, the meter time module 80 further includes a first time signal output module 84. The first time signal output module 84 can output the signal of the meter time, thereby realizing the sharing of the meter time.
As shown in fig. 6, the vehicle body time module 72 includes a third time signal receiving module 721, a second clock module 722 and a second time signal output module 723. The third time receiving module 721 is used for receiving a time signal. The third time receiving module 721 is transmitted to the second clock module 722, so that the second clock module 722 clocks according to the time signal received by the third time receiving module 721, thereby generating a vehicle main body time. The second time signal output module 723 outputs the car body time, thereby implementing the sharing of the car body time.
According to the fifth preferred embodiment of the present invention, when the vehicle of the vehicle is powered on and started, the vehicle body time recorded by the second clock module 722 of the vehicle body time module 72 is outputted to the vehicle body time module 90 by the second time signal output module 723, and is received by the first time signal receiving module 91 and is further presented by the vehicle body time presenting module 92. At this time, the car time displayed by the car machine is synchronized with the car body time outputted by the car body time module 72. When the third time signal receiving module 721 of the vehicle body time module 72 receives the meter time outputted by the meter time module 80, the second time signal outputting module 723 of the vehicle body time module 72 outputs the signal of the meter time received by the third time signal receiving module 721 to the first time signal receiving module 91 of the vehicle time module 90, and then presents the signal through the vehicle time presenting module 92. At this time, the on-board time presented by the on-board time module 90 is synchronized with the meter time presented by the meter time module 80.
When the GPS time module 7111 of the time signal module 711 obtains GPS time, the time signal module 711 sends a GPS time signal to the third time signal receiving module 721 of the automobile main body time module 72 and counts time through the second clock module 722 to update the automobile main body time. If the automatic update switch 7121 is in the on state when the GPS time module 7111 obtains the GPS time, the GPS time module 7111 can be synchronized with the on-board time module 90 and the meter time module 80 and presented through the on-board time presentation module 92 and the meter time presentation module 83, respectively. Thus, the vehicle time and the meter time progress is synchronized to the GPS time.
When the user needs to set the time by himself, he can obtain the user time set by the user through the user time module 7112. When the user time module 7112 obtains the user time, the time signal module 711 synchronizes the user time to the vehicle time module 90 and the meter time module 80 and respectively displays the user time through the vehicle time display module 92 and the meter time display module 83. Thus, the vehicle time and the meter time progress are synchronized to the user time.
If the auto-update switch 7121 is turned on, the car machine time and the meter time may be updated and kept synchronized. Specifically, when the automatic update switch 7121 is turned on, after the automatic update instruction receiving module 7122 receives the time update instruction, the GPS time module obtains the GPS time and synchronizes it to the onboard vehicle time module 90 and the meter time module 80 through the vehicle body time module 72, so that the onboard vehicle time and the meter time can be synchronized in real time.
