Refer to the vehicle mounted guidance based on dual system that Fig. 1, Fig. 1 are the offer according to a preferred embodiment of the invention fast
Speed driving method, the method is completed by vehicle electronic device, and this vehicle electronic device includes RS232 interface, by RS232 interface
It is connected with the ECU of vehicle, as it is shown in figure 1, comprise the steps:
Step S101, vehicle electronic device are by the air-conditioning information in the ECU of RS232 equipment and vehicle；
Vehicle electronics is for increasing electronic system and the product of automobile function on automobile.Vehicle electronics includes vehicle-mounted sound
Acoustic system, navigation system, vehicle information system and vehicle-mounted household appliances etc..Vehicle-mounted computer (CarPC), In-vehicle networking and cruise system
Automobile is become a new IT and communication center by system, and vehicle audio, in-car TV, car refrigerator etc. also meet user couple
The needs of vehicle-mounted home appliance.Vehicle audio is the equipment that in vehicle electronics product, popularity rate is the highest, and model change is city
The important motivity of field development.In existing on-vehicle acoustic apparatus, the popularity rate of CD player is more than 80%, but DVD player and MP3 audio frequency
The assembly rate or at a fairly low of dispatching from the factory of equipment, has a high potential.
One of communication interface of S232, by Electronic Industries Association (Electronic Industries Association,
EIA) the asynchronous transmission standard interface formulated.Generally RS-232 interface is with 9 pins (DB-9) or 25 pins (DB-25)
Kenel occur, general personal computer has two groups of RS-232 interface, is called COM1 and COM2.
RS-232-C is that EIA EIA (Electronic Industry Association) formulates
A kind of serial physical interface standards.RS is the abbreviation of English " proposed standard ", and 232 is identification number, and C represents amendment number of times.RS-
232-C bus standard is provided with 25 signal line, including a main channel and an accessory channel.
Mainly use main channel, for general duplex communication, it is only necessary to several signal line achieve that, as
Article one, send line, a reception line and a ground wire.
The message transmission rate that RS-232-C standard specifies is 50,75,100,150,300,600,1200,2400,4800,
9600,19200,38400 baud.
RS-232-C standard specifies, driver allows the capacitive load of 2500pF, and communication distance will be limited by this electric capacity,
Such as, when using the communication cable of 150pF/m, maximum communication distance is 15m；If every meter of cable capacitance reduce, communicate away from
From increasing.Short another reason of transmission range is that RS-232 belongs to single-ended signal transmission, there is common Earth noise and can not suppress
The problems such as common mode disturbances, within being therefore generally used for 20m
Rs232 (9 pin) interface
Communication.Concrete communication distance is also relevant with traffic rate, such as, when 9600pbs, during common twisted-pair shielded wire,
Distance is up to 30-35 rice.
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 microcomputer.It is the same with common single-chip microcomputer, by micro-
Processor (CPU), memorizer (ROM, RAM), input/output interface (I/O), analog-digital converter (A/D) and shaping, driving
Form in large scale integrated circuit.
The voltage power supply scope of ECU typically at 6.5-16V (internal key aspect have stable-pressure device), operating current at 0.015-
0.1A, operating temperature are at subzero 40-80 degree.Can bear the vibration of below 1000Hz, the probability that therefore ECU damages is the least,
In ECU, CPU is core, and it has the function of computing and control, and operationally, it gathers the letter of each sensor to electromotor
Number, carry out computing, and the result of computing is changed into control signal, control the work of controlled device.It is also carried out memorizer
(ROM, RAM), input/output interface (I/O) and the control of other external circuit；The program deposited in memorizer ROM be through
Based on accurately calculating the data taken with great many of experiments, this intrinsic program, when electromotor works, is constantly come with collection
The signal of each sensor compares and calculates.The igniting of output control electromotor compared and calculate, air-fuel ratio, idling,
The control of the multiple parameters such as waste gas recirculation.It also has fault self-diagnosis and defencive function, and when system produces fault, it can also
Automatic record failure code use protective measure to read alternative program from above-mentioned intrinsic program to maintain and start in RAM
The operating of machine, makes automobile can reach repair shop.
Step S102, the virtual key of generation air conditioner operation, show this virtual key on touching display screen；
The method of the virtual key generating air conditioner operation 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 of reception user's input, be converted into CAN order by this 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 with research and development and life
Produce the famous German BOSCH company exploitation of automobile electronics, and eventually become international standard (ISO 11898), be international
One of upper most widely used fieldbus.In North America and West Europe, CAN agreement has become as Computer Controlled System for Vehicle
With the STD bus of built-in industrial control area net（CAN）, and have and aim at high capacity waggon and heavy industry machine with CAN for underlying protocol
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.In automobile industry, for safety, comfortableness, convenience, low public hazards, the requirement of low cost, various
Electronic control system be developed.Due to data type used and the requirement to reliability of communicating between these systems
Being not quite similar, situation about being made up of multiple bus is a lot, and the quantity of wire harness is consequently increased.For adapting to " reduce the number of wire harness
Amount ", the needs of " by multiple LAN, carry out the high-speed communication of mass data ", within 1986, electrically business Bosch of Germany develops
CAN communication agreement towards automobile.Hereafter, CAN has carried out standardization by ISO11898 and ISO11519, has been vapour in Europe
The standard agreement of car network.
The high-performance of CAN and reliability are admitted, and be widely used in industrial automation, boats and ships, armarium,
The aspects such as industrial equipment.Fieldbus is one of focus of nowadays automatic art, is described as automatic field
LAN.Its dcs that appears as realizes data communication real-time between each node, reliable and provides
Strong technical support.
The technical scheme that the present invention provides achieves vehicle electronic device and realizes the control of air-conditioning, makes so it has user
With convenient, the advantage that user experience is high.
