Problems solved by technology

[0002] In the prior art, the car's instrument and car technology will time separately, but the two will cause inconsistent time due to various reasons. The inconsistent time will cause two times in the vehicle system, which is unfriendly to the user experience. , with the development of intelligent technology, the whole vehicle needs to realize the unification of clock display
However, there is no relevant public document on the unified instrument and vehicle technology clock in the prior art

Embodiment Construction

[0014] The specific implementation manner of the present invention will be described in further detail below by describing the best embodiment with reference to the accompanying drawings.

[0015] The design time reference of the present invention is an instrument, and the instrument and the locomotive are timed separately;

[0016] 2. When│instrument time-vehicle time│≥5s, the vehicle receives the instrument time;

[0017] 3. After the user sets the time from the car terminal, the instrument needs to display the time sent by the car;

[0018] 4. In the same power-on cycle, after the network wakes up, the car will send the time to the meter with a delay of about 10s (the time sent by the meter will not be processed within 10s).

[0019] figure 1 It is a flow chart of a clock synchronization method based on an automobile instrument and a vehicle machine according to the present invention, and the flow is based on a clock signal without GPS. The system block diagram involves ...

Abstract

The invention discloses a clock synchronization method for an automobile instrument and an automobile machine, which comprises the following steps of: after the automobile machine and the instrument are electrified, comparing the system time of the automobile machine with the system time of the instrument, and when the difference between the system time of the automobile machine and the system time of the instrument is less than a set time threshold value, timing the automobile machine and the instrument by adopting respective system time; otherwise, unifying the system time of the vehicle machine and the instrument. The method has the advantages that the method is simple and fast, the method can be integrated in the vehicle machine and the instrument through software, unification and updating of the time and the instrument are fast, hardware is not added, only software updating is needed, cost is low, and applicability is high.

Description

technical field [0001] The invention relates to the field of automobile system control, in particular to a method for synchronizing an automobile instrument and an automobile clock. Background technique [0002] In the prior art, the car's instrument and car technology will time separately, but the two will cause inconsistent time due to various reasons. The inconsistent time will cause two times in the vehicle system, which is unfriendly to the user experience. , with the development of intelligent technology, the whole vehicle needs to realize the unification of clock display. And there is not the open document of relevant unified meter and vehicle technology clock in the prior art. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art, and provide a method for synchronizing the clocks of the car instrument and the car machine, which is used to realize the unification of the time of the car instrument and...
