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,
