The utility model embodiment adds self-checking function in combination instrument, when instrument shows fault, save the complicated processes that the maintainer investigates one by one to each parts.
The automobile combination meter automatic trouble locating arrangements of the utility model embodiment is the hardware cell that runs in the combination instrument of various automobiles, can be used as also independently that suspension member is integrated into automobile, perhaps in the automobile combination meter.
The constructional drawing of the automobile combination meter automatic trouble locating arrangements that Fig. 1 provides for the utility model embodiment comprises:
Self check starts control unit 81, is connected with combination instrument, is used for according to the self check enabled instruction, and the control combination instrument enters the self check state;
Self-test unit 82 is connected control unit with combination instrument with self check and is connected, and being used for after combination instrument enters the self check state item by item, the function to combination instrument checks;
Unit in the automobile combination meter automatic trouble locating arrangements that the utility model embodiment provides is all realized with hardware, is simply described as follows.
Start control unit such as self check and have an interface, be used for receiving and outsidely press the self check enabled instruction of rear transmission by hardware button, perhaps detect by interface and judge and to enter self check that brief description is as follows behind the state of external hardware unit.
Self check starts control unit and detects key state and mileage reset button, judges that needs enter self check according to the time sequential routine of key and mileage reset button.
When being in the tail-off shelves such as key, detecting the mileage reset button and be pressed, then detect key and be transformed into the engine starting shelves from the tail-off shelves, the mileage reset button unclamps after the last schedule time, then judges to enter self check.
Above-mentioned only is the sequential judgement of button, key state, can realize by various hardware circuits, does not elaborate at this.
Self check starts control unit can send a low level signal to combination instrument, and then combination instrument can enter the self check state.
And self-test unit, only need to generate control command by hardware circuit, send in the combination instrument, and receive the response data of current detection instrument by hardware circuit after, then generate control command and the transmission of another instrument, by the response data of hardware circuit reception current detection instrument ... so move in circles, realize detecting.
After self-test unit detects and finishes, change the level of an interface, and after self check withdraws from control unit and can withdraw from by the electrical level judging self check that detects this interface, the control combination instrument transfers normal condition to from the self check state, as sending a high level signal to combination instrument, then combination instrument can transfer normal condition to from the self check state.
Certainly, a kind of possible hardware simplicity that more than only is said units realizes that the utility model embodiment is not limited to upper type.
Fig. 2 shows the diagram of circuit of the automobile combination meter self checking method that the utility model embodiment provides, and details are as follows:
In step S101, according to the self check enabled instruction, the control combination instrument enters the self check state; As send the electric signal of a specific time sequence to combination instrument, such as a low level signal.
As an embodiment of the present utility model, the self check enabled instruction can be when key is in the tail-off shelves, pins the mileage reset button of combination instrument, key is got to the engine starting shelves again, combination instrument enters the self check state after waiting for setting-up time, unclamps the mileage reset button.
In step S102, item by item the function of combination instrument checked;
In the utility model embodiment, combination instrument comprises coolant temperature alert light, average speed indicator, read-out etc.The inspection item of self check comprises coolant temperature alert light self check, average speed indicator self check, the self check of display screen functions information etc.
In step S103, receive the self check exit instruction, the control combination instrument transfers normal condition to from the self check state.As send the electric signal of another specific time sequence to combination instrument, such as a high level signal.
As an embodiment of the present utility model, the self check exit instruction can also under the self check state by the mileage reset button to setting-up time (can realize in conjunction with the state of mileage reset button by a time meter), perhaps the self check state continuance is perhaps got to key tail-off shelves (can realize by a key state reading device) to setting-up time threshold value (can realize by a time meter).
The utility model embodiment has reduced maintainer's manual operation by for combination instrument adds self-checking function, has not only simplified the investigation failure process, also helps the very fast understanding source of trouble of maintainer, improves investigation efficient.
Shown in Fig. 3 is the detailed process of the automobile combination meter process of self-test that provides of the utility model embodiment, and details are as follows:
In step S201, start combination instrument and enter the self check state;
Start combination instrument and enter the self check state specifically in the following manner:
When key is in the OFF gear, pin first the mileage reset button of combination instrument, again key is got to the ON shelves, enter Auto-Sensing Mode behind the 5s, unclamp the mileage reset button.
In step S202, carry out item by item the function self check of combination instrument;
In step S203, the coolant temperature alert light self check;
In step S204, the average speed indicator self check;
The average speed indicator indication that circulates between 10km/h → 45km/h → 85km/h → 125km/h → 165km/h → 125km/h → 85km/h → 45km/h → 10km/h, each transformation period is 2s, as shown in Figure 4.
In step S205, the self check of display screen functions information;
In step S206, enter the self check state after, short mileage reset button (button time t＜3s) for example, the switching screen content press.
In the utility model embodiment, read-out has four kinds of show states, is described as follows:
The first screen: fuel oil, water temperature, clock are normally indicated, and the mileage district shows 011500, enters this value of self check state at every turn and remains unchanged.The rotating speed district shows 70, and numeral 7 is with the 0.5Hz frequency scintillation, and numeral 0 is not glimmered, as shown in Figure 5.
The second screen: read-out shows full section segment encode, such as Fig. 6.
The 3rd shields such as Fig. 7: fuel oil, water temperature, clock are normally indicated, and the mileage district shows the sampled value of current fuel sensor resistance value.As shown in Figure 7, speed gage shows 70, and numeral 7 is with the 0.5Hz frequency scintillation, and numeral 0 is not glimmered.
The 4th screen: fuel oil, water temperature, clock are normally indicated, and mileage meter shows the sampled value of current cooling-water temperature sensor resistance value.As shown in Figure 8, the rotating speed district shows 70, and numeral 7 is with the 0.5Hz frequency scintillation, and numeral 0 is not glimmered.
In step S207, withdraw from the self check state, recover the combination instrument normal condition.Concrete operations are as follows:
Length is pressed mileage reset button 5s under the self check state, and perhaps self check reaches 5 minutes, after perhaps key reaches the OFF shelves, can withdraw from the self check state.
The utility model embodiment has realized the self check of combination instrument function, when the maintainer runs into the instrument fault phenomenon, need not to change one by one combination instrument or related components, namely know source of trouble, remove the in the past complicated processes of investigation from, improved simultaneously investigation efficient.
The above only is preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
