Brief description of the drawings
Fig. 1 represents the attachment structure schematic diagram of the clock system of automobile in the embodiment of the present invention.
Specific embodiment
It is right below in conjunction with the accompanying drawings and the specific embodiments to make the object, technical solutions and advantages of the present invention clearer The present invention is described in detail.
Shown in reference picture 1, the invention provides a kind of automobile, including:Host computer system (EHC) 1;Gateway (GW) 2, with main frame System 1 is connected by entertainment systems bus (IBUS) 10;Car body controller (BCM) 3, bodywork system bus is passed through with gateway (EBUS) 20 connection;Electronic clock (EC) 4, is connected, institute with the car body controller 3 by LIN (local interconnect network) line 30 The time signal of the transmission of host computer system 1 is stated, the entertainment systems bus 10, the gateway 2, bodywork system bus is passed sequentially through 20th, car body controller 3 and LIN lines 30 are transmitted to electronic clock 4, the electronic clock 4 receive the time signal and pair when Between synchronize.
In automobile of the invention, host computer system 1 by entertainment systems bus 10, gateway 2 and bodywork system bus 20 by when Between signal be sent on car body controller 3, after car body controller 3 receives time signal, forwarding electronic clock 4, electronic clock 4 Synchronized after receiving time signal so that the time of electronic clock 4 is identical with the time of host computer system 1.The present invention is used The flexibility of bussing technique, it is ensured that independence, the reliability of time signal interaction, solve electronic clock and host computer system when Between nonsynchronous problem.
Wherein, entertainment systems bus 10 and bodywork system bus 20 are a part for vehicle CAN.
Specifically, electronic clock 4 includes:Local internet LIN interfaces, the car body controller 3 by LIN lines 30 with The LIN interfaces connection;LIN transceivers, are connected with the LIN interfaces, obtain the time signal.
Electronic clock 4 also includes:Power line and ground wire;Electronic clock 4 is connected by power line with the storage battery of automobile, institute Electronic clock 4 is stated by the ground connection.
Wherein, LIN transceivers are used for receiving and transmitting signal.LIN transceivers receive what car body controller 3 sent by LIN lines 30 Time signal.After LIN transceivers receive LIN signals, the in house software of electronic clock 4 first judge whether LIN time services correct (when, Point, whether the second is virtual value).When correct, into clock adjustment modes, program internal judgment LIN time services and original clock itself The time difference of internal clocking, position, direction that minute hand is rotated are judged by the time difference.
In order to realize the connection of host computer system 1, gateway 2 and car body controller 3 and bus in CAN network, to gateway 2, car Connection between body controller 3 and host computer system 1 and bus is set.Gateway 2 is respectively by terminal resistance and amusement system System bus 10 and bodywork system bus 2 are connected;Host computer system 1 is connected by separate terminal with entertainment systems bus 10;Vehicle body control Device processed 3 is connected by separate terminal with bodywork system bus 20.Wherein, the communications speed of gateway 2 and host computer system 1 is 500kbps, gateway 2 and the communications speed of car body controller 3 are 125kbps.The hardware of electronic clock 4 is upgraded, LIN interfaces and LIN transceivers are added in electronic clock 4, the LIN communications speed of 19.2kbps (kbit/s), electronics is supported Clock 4 is articulated on the LIN nodes of car body controller 3.
Wherein, host computer system 1 includes navigator, in-car TV or electronic equipment etc. vehicle-mounted computer, and host computer system 1 is connected to In the entertainment systems bus 10 of CAN network.
The workflow of the clock system of automobile of the present invention is introduced below by specific form of implementation.
Host computer system 1 is when every task (such as start to navigate, browse webpage etc.) by time signal with message Form sends.Time message includes:The first frame of hour signal is recorded, the second frame of minute signal is recorded and is recorded second signal 3rd frame.Time message totally three frame, the entitled EHC_3 of time message, comprising time signal have hour, minute and second.When Between three frames of message EHC_3 be respectively EHC3_N_Hour, EHC3_N_Minute, EHC3_N_Second.By time signal with three The time message of frame sends, it is ensured that after electronic clock 4 receives time signal, according to the small of the accurate adjustment time of each frame When, minute and second, be conducive to the accuracy of clock system.Simultaneously after the time signal of wherein a certain frame is lost, electricity is not influenceed The time adjustment that sub-clock is carried out according to remaining other frames of time message, so as to be conducive to the stability of whole clock system.
The time message EHC_3 that gateway 2 sends host computer system 1 is forwarded to bodywork system bus from entertainment systems bus 10 20。
Car body controller 3 receives message EHC_3, and the message is forwarded when message EHC_3 changes to LIN lines 30, turns It is dealt into signal respectively BCM_N_Hour, BCM_N_Minute, BCM_N_Second on LIN.
Electronic clock 4 is receiving the time signal that car body controller 3 sends by LIN lines 30:BCM_N_Hour、BCM_ N_Minute, BCM_N_Second, update the time of itself, and directly voluntarily adjustment display immediately.So pass through CAN skill Art realizes electronic clock and is adjusted with large-size screen monitors time synchronized.
Each embodiment in this specification is described by the way of progressive, what each embodiment was stressed be with The difference of other embodiment, between each embodiment identical similar part mutually referring to.
Above-described is the preferred embodiment of the present invention, it should be pointed out that the ordinary person for the art comes Say, some improvements and modifications can also be made under the premise of principle of the present invention is not departed from, and these improvements and modifications also exist In protection scope of the present invention.
