Abstract
The utility model discloses a motor meter and a diagnostic system thereof. The motor meter comprises a single-chip microcomputer of which the input end is connected with a signal acquisition interface and the output end is connected with an indicator light, a display screen and a motor drive respectively, the motor drive is connected with a state table, the utility model is also characterized in that the motor meter also comprises a diagnostic device for detecting whether the indicator light, the display screen and the state table can work normally, the diagnostic device is connected with the single-chip microcomputer through a CAN bus. The diagnostic system communicates with a meter controller through a CAN line, the line connection is simple, and a meter can be forced to perform a diagnostic mode and perform a diagnostic test to each function through the communication between the diagnostic system and the meter when the meter loses the self-diagnostic function.
Description
Technical field
The utility model relates to a kind of instrument and diagnostic system thereof of automobile, and relates in particular to the instrument diagnostic system of hybrid vehicle or electric motor car.
Background technology
In order to make the user can grasp the working condition of automobile and each system thereof at any time, various indicating instruments and various warning device are housed on the instrument panel of automobile cab, comprise speedometer, mileometer, fuel gauge, car speed alarm device, status indicator lamp and alarm lamp etc. on the instrument panel on the automobile usually.
The in good time indication of combination instrument is reminded with caution traffic safety is played very important pre-suggesting effect, can notify human pilot to make measures areput in good time.So various indications and information warning for instrument should carry out the necessary function self check when powering on, to guarantee that normally whether the every indication of instrument, alarm function, the local detection certainly that powers on of traditional instrument, but a lot of detection indications are not to be controlled by instrument, the detection certainly that is actually external module from the detection state is indicated, and instrument is indicated, whether the caution partial function normally can not embody.
The utility model content
The purpose of this utility model provides a kind of automobile instrument and diagnostic system thereof, controller can be selected to enter diagnostic mode and carries out comprehensive self diagnosis process when instrument powers on, and the personnel that maintain easily carry out fault to it and get rid of and before driving whether the instrument running status is well confirmed.
A kind of automobile instrument and diagnostic system thereof, comprise single-chip microcomputer, described single-chip microcomputer input end connects the signals collecting interface, output terminal connects pilot lamp, display screen and motor-driven respectively, described motor-driven connection status table, it is characterized in that: also comprise and detect the diagnostic device that can described pilot lamp, described display screen and described state table operate as normal, described diagnostic device links to each other with described single-chip microcomputer by the CAN bus.
Automobile instrument described in the utility model and diagnostic system thereof pass through the CAN bus communication with instrument controller, and line is simple, can be when the instrument self-diagnostic function loses, by the communication of diagnostic system and instrument, allow instrument force to carry out diagnostic mode, and every function is carried out diagnostic test.
Description of drawings
Fig. 1 is the structural drawing of a kind of embodiment of instrument system of the present utility model;
Fig. 2 has shown the control method process flow diagram of instrument system of the present utility model.
Embodiment
Describe the utility model in detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of automobile instrument and diagnostic system thereof, comprise single-chip microcomputer 1, described single-chip microcomputer input end connects the signals collecting interface, output terminal connects pilot lamp 2, display screen 3 and motor-driven 4 respectively, described motor-driven 4 connection status tables is characterized in that: also comprise and detect the diagnostic device 5 that can described pilot lamp 2, described display screen 3 and described state table operate as normal, described diagnostic device links to each other with described single-chip microcomputer 1 by CAN bus 6.Described state table comprises voltameter 7, speedometer 8, fuel gauge 9 and mileometer 10, and described signals collecting interface is gathered input switch amount input signal and analog quantity input signal.Described single-chip microcomputer is controlled described pilot lamp 2, described display screen 3 and described state table operate as normal according to the switching value signal and the analog signals that collect through the signal conversion module conversion.
Described diagnostic device comprises keyboard, and whether to the single-chip microcomputer input command, can detect described pilot lamp 2, described display screen 3 and described state table can operate as normal by the CAN bus for described keyboard.Described diagnostic device also comprises display, and described display can be used for showing the input information by keyboard, so that the control personnel compare the structure that input information and instrument show, to judge the quality of instrument.
As shown in Figure 2, described single-chip microcomputer 1 carries out the work self check earlier when work, detecting current mode of operation then is normal mode of operation or diagnostic mode, when normally entering mode of operation, then instrument, display screen and state table operate as normal show the state of current vehicle; When entering diagnostic mode, whether described single-chip microcomputer 1 is normal by keyboard input command measuring instrument, display screen and state table.
When described single-chip microcomputer 1 is operated in the described normal mode of operation, vehicle normally moves, this single-chip microcomputer 1 is correspondingly controlled voltameter 7, speedometer 8, fuel gauge 9 and mileometer 10 and is shown, single-chip microcomputer 1 control voltameter 7 shows current electric quantity, control speedometer 8 shows the current speed of a motor vehicle, control fuel gauge 9 shows the oil mass of current vehicle, and control mileometer 10 shows the distance travelled of vehicle, and state of a control pilot lamp 2 shows the current vehicles state.
When single-chip microcomputer 1 is operated in described diagnostic mode, whether detect vehicular meter can operate as normal, described diagnostic device comprises keyboard and display, the control personnel use keyboard to need data presented to controller input instrument, the data presentation of being imported is on display, data-signal is input to single-chip microcomputer by the CAN bus, video data by state table compares with the data of being imported, to judge that state table whether can operate as normal, if instrumentation is unusual, can change instrument; Can also brighten by input media input of control commands such as keyboard control pilot lamp, if pilot lamp does not brighten, can change, to avoid the generation of accident to pilot lamp.
Claims (4)
1, a kind of automobile instrument and diagnostic system thereof, comprise single-chip microcomputer, described single-chip microcomputer input end connects the signals collecting interface, output terminal connects pilot lamp, display screen and motor-driven respectively, described motor-driven connection status table, it is characterized in that: also comprise and detect the diagnostic device that can described pilot lamp, described display screen and described state table operate as normal, described diagnostic device links to each other with described single-chip microcomputer by the CAN bus.
2, system according to claim 1 is characterized in that: described diagnostic device comprises keyboard.
