Abstract
The invention discloses a kind of test methods of automobile combination meter, it is related to automobile combination meter technical field, specially a kind of test method of automobile combination meter, including combination instrument and combination instrument replacing part, by conducting wire and combination instrument replacing part, electrically output connects the combination instrument, and is electrically connected in series between combination instrument and combination instrument replacing part by conducting wire.Alternative combinations instrument: the test method of the automobile combination meter substitutes this measurand of automobile combination instrument using PC computer and CAN box completely；The configuration of CANoe host computer: VCU node is simulated by CANoe to issue various test signals；This test method can be introduced in the initial development stage of combination instrument, dramatically reduces the test period of combination instrument, can be solved the problems, such as at the research and development initial stage of combination instrument, vehicle is reduced and researches and develops cost.
Description
Technical field
The present invention relates to automobile combination meter technical field, specially a kind of test method of automobile combination meter.
Background technique
As the vehicle R&D cycle is constantly compressed, the novel compositions instrument of industrial personal computer, CAN box and liquid crystal display composition is used
Table quietly rises, a kind of to use CANoe, PC computer, CAN box as the combination instrument test of hardware for this combination instrument
Method, not needing true combination instrument hardware just can make the functional test coverage rate of combination instrument reach 100%.
But existing automobile combination meter internal structure external structure is more unified, mode of operation in use is more
Simply, the disadvantages of and cost of manufacture of a combination thereof instrument is higher, cannot meet the use demand of people very well.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of test methods of automobile combination meter, solve above-mentioned
The problem of being proposed in background technique.
In order to achieve the above object, the present invention is achieved by the following technical programs: a kind of test of automobile combination meter
Method, including combination instrument and combination instrument replacing part, the combination instrument are electrically defeated by conducting wire and combination instrument replacing part
It connects, and is electrically connected in series between combination instrument and combination instrument replacing part by conducting wire out.
Optionally, the combination instrument includes microcomputer, liquid crystal display and CAN box, and microcomputer, liquid crystal display and
Electrically be connected in parallel between CAN box by conducting wire, and microcomputer, liquid crystal display and CAN box pass through conducting wire with combine instrument
It is electrically connected in series between table replacing part.
Optionally, the combination instrument replacing part is internally provided with PC computer, and microcomputer, liquid crystal display and CAN
Box passes through electrically output connection between conducting wire and PC computer.
The present invention provides a kind of test method of automobile combination meter, have it is following the utility model has the advantages that
1, alternative combinations instrument: this measurand of automobile combination instrument is substituted completely using PC computer and CAN box；
2, CANoe host computer configures: simulating VCU node by CANoe to issue various test signals；
3, this test method can be introduced in the initial development stage of combination instrument, dramatically reduces combination instrument
Test period can solve the problems, such as at the research and development initial stage of combination instrument, reduce vehicle and research and develop cost.
Detailed description of the invention
Fig. 1 is the electrical flow diagram of the present invention；
Fig. 2 is alternative combinations instrument electrical property flow diagram of the present invention.
In figure: 1, combination instrument；101, microcomputer；102, liquid crystal display；103, CAN box；2, combination instrument replacing part；
3, PC computer.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
Fig. 1 to Fig. 2 is please referred to, the present invention provides a kind of technical solution: a kind of test method of automobile combination meter, including
Combination instrument 1 and combination instrument replacing part 2, by conducting wire and combination instrument replacing part 2, electrically output connects combination instrument 1, and
It is electrically connected in series between combination instrument 1 and combination instrument replacing part 2 by conducting wire；
Combination instrument 1 includes microcomputer 101, liquid crystal display 102 and CAN box 103, and microcomputer 101, liquid crystal display
It is electrically connected in parallel between 102 and CAN box 103 by conducting wire, and microcomputer 101, liquid crystal display 102 and CAN box 103 are equal
By being electrically connected in series between conducting wire and combination instrument replacing part 2；
Combination instrument replacing part 2 is internally provided with PC computer 3, and microcomputer 101, liquid crystal display 102 and CAN box
103 pass through electrically output connection between conducting wire and PC computer 3.
In conclusion the test method of the automobile combination meter is as follows:
Principle 1: alternative combinations instrument:
Including: PC computer and CAN box substitute automobile combination instrument completely: industrial personal computer is exactly PC computer, so journey
Sequence is used directly for PC computer, and liquid crystal display is only intended to show, the display function of liquid crystal display may be implemented in the display of PC computer
Can, it is illustrated in fig. 2 shown below；
The configuration of principle 2:CANoe host computer:
VCU node is simulated by CANoe to issue various test signals, and test signal content includes: signal light control, text
Prompt, motor speed, speed, residual fuel amount etc.；
CANoe host computer configures See Figure explanation: including an IG module, sends various letters required for combination instrument
Number, various information can be shown on the host computer picture of PC, functional test is carried out to combination instrument；Such as
VCUVehDrivemode=1 while VCUGearSt=3；Vehicle gear is represented at P grades, ECO economic model, on combination instrument
It can show ECO mode.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
