Referring to FIG. 1, Fig. 1 is fast according to the vehicle mounted guidance based on dual system provided of a preferred embodiment of the invention
Fast driving method, this method are completed by vehicle electronic device, which includes RS232 interface, pass through RS232 interface
It is connected with the ECU of vehicle, as shown in Figure 1, including the following steps:
Step S101, vehicle electronic device obtains the air-conditioning information in the ECU of vehicle by RS232 equipment；
Vehicle electronics is on automobile for increasing the electronic system and product of automobile function.Vehicle electronics includes vehicle-mounted sound
Acoustic system, navigation system, vehicle information system and vehicle-mounted household appliances etc..Vehicle-mounted computer (Car PC), In-vehicle networking and cruise
Automobile is become a new IT and communication center by system, and vehicle audio, in-car TV, car refrigerator etc. also meet user
To the needs of vehicle-mounted household appliance.Vehicle audio is that the highest equipment of popularity rate, successive generations of products are in vehicle electronics product
The important motivity of market development.In existing on-vehicle acoustic apparatus, the popularity rate of CD player is more than 80%, but DVD player and MP3 sound
The factory assembly rate of frequency equipment or at a fairly low, has a high potential.
One of communication interface of S232, by Electronic Industries Association (Electronic Industries Association,
EIA) prepared asynchronous transmission standard interface.Usual RS-232 interface is with 9 pins (DB-9) or 25 pins (DB-25)
Kenel occur, have two groups of RS-232 interfaces in general personal computer, be referred to as COM1 and COM2.
RS-232-C is that American Electronics Industry Association EIA (Electronic Industry Association) is formulated
A kind of serial physical interface standards.RS is the abbreviation of English " proposed standard ", and 232 be identification number, and C indicates modification number.RS-
232-C bus standard is equipped with 25 signal lines, including a main channel and an accessory channel.
Main channel is mainly used in most cases, for general duplex communication, it is only necessary to which several signal lines achieve that, such as
One transmission line, a reception line and a ground wire.
Message transmission rate as defined in RS-232-C standard be 50,75,100,150,300,600,1200,2400,4800,
9600,19200,38400 baud.
RS-232-C standard regulation, the capacitive load that driver allows to have 2500pF, communication distance will be limited by this capacitor,
For example, using 150pF/m communication cable when, maximum communication distance 15m；If the capacitance of every meter of cable reduces, communication away from
From can increase.Short another of transmission range there are total Earth noise and cannot inhibit the reason is that RS-232 belongs to single-ended signal transmission
The problems such as common mode interference, therefore be generally used within 20m
Rs232 (9 needle) interface
Communication.Specific communication distance is also related with traffic rate, for example, in 9600pbs, when common twisted-pair shielded wire,
Distance is up to 30-35 meters.
ECU (Electronic Control Unit) electronic control unit, also known as " car running computer ", " vehicle-mounted computer " etc..
It is then automobile specified microcomputerized controller from purposes, is also automobile specified single-chip microcontroller.It is as common single-chip microcontroller, by micro-
Processor (CPU), memory (ROM, RAM), input/output interface (I/O), analog-digital converter (A/D) and shaping, driving
Equal large scale integrated circuits composition.
The voltage power supply range of ECU is generally in 6.5-16V (internal key aspect has stable-pressure device), operating current in 0.015-
0.1A, operating temperature are in subzero 40-80 degree.1000Hz vibration below can be born, therefore the probability of ECU damage is very small,
CPU is core in ECU, it has the function of operation and control, and at runtime, it acquires the letter of each sensor to engine
Number, operation is carried out, and the result of operation is changed into control signal, controls the work of controlled device.It is also carried out to memory
The control of (ROM, RAM), input/output interface (I/O) and other external circuits；The program stored in memory ROM be by
Based on accurately calculating the data taken with many experiments, this intrinsic program when the engine is working, is constantly come with acquisition
The signal of each sensor is compared and calculates.Compare and calculate the result control igniting of engine, air-fuel ratio, idling,
The control of the multiple parameters such as exhaust gas recycling.There are also fault self-diagnosis and defencive function for it, and when system generates failure, it can also
Fault code is automatically recorded in RAM and reads alternative program from above-mentioned intrinsic program using safeguard measure to maintain to start
The operating of machine, enables automobile to reach repair shop.
Step S102, the virtual key for generating air conditioner operation, which is shown on touching display screen；
The method that the virtual key of air conditioner operation is generated in above-mentioned steps can use interface creating method, and the present invention is not
Limit the generation method of above-mentioned virtual key.
Step S103, the control command for receiving user's input, is converted into CAN bus order for the control command, and CAN is total
Line order is sent to vehicle ECU to realize the control of air-conditioning.
The conversion regime of the order of above-mentioned steps S103 can be realized by conventional order conversion regime.
CAN is the abbreviation of controller local area network (Controller Area Network, CAN), is by research and develop and give birth to
The famous German BOSCH company exploitation of automobile electronics is produced, and eventually becomes international standard (ISO 11898), is international
One of upper most widely used fieldbus.In North America and West Europe, CAN bus agreement has become Computer Controlled System for Vehicle
With the STD bus of built-in industrial control area net(CAN), and possesses and aim at large-sized truck and heavy industry machine by underlying protocol of CAN
The J1939 agreement of tool Car design.
CAN is the abbreviation (hereinafter referred to as CAN) of Controller Area Network, is the serial of ISO International standardization
Communication protocol.It is various for the requirement to safety, comfort, convenience, low nuisanceless, low cost in automobile industry
Electronic control system be developed.Due to communicating data type used between these systems and to the requirement of reliability
There are many case where being not quite similar, being made of multiple bus, and the quantity of harness is consequently increased." number of harness is reduced for adaptation
Amount ", the needs of " by multiple LAN, carrying out the high-speed communication of mass data ", electrical quotient Bosch, Germany in 1986 develops
CAN communication agreement towards automobile.Hereafter, CAN is standardized by ISO11898 and ISO11519, has been vapour in Europe
The standard agreement of vehicle network.
The high-performance and reliability of CAN is accepted, and be widely used in industrial automation, ship, Medical Devices,
Industrial equipment etc..Fieldbus is one of the hot spot of nowadays automatic field technology development, is known as automatic field
Computer LAN.Its appearance realizes that real-time, reliable data communication provides between each node for dcs
Strong technical support.
Technical solution provided by the invention realizes the control that vehicle electronic device realizes air-conditioning, so it makes with user
With convenient, the high advantage of user experience.
Referring to FIG. 2, Fig. 2 is the vehicle mounted guidance based on dual system provided according to another preferred embodiment of the present invention
Fast driving method, this method are completed by vehicle electronic device, which includes RS232 interface, are connect by RS232
Mouth is connected with the ECU of vehicle, as shown in Fig. 2, including the following steps:
