Abstract
The utility model relates to a vehicle maintenance prompting device which comprises a microprocessor, a storage device, a display device, a timer and a CAN bus communication module. According to the vehicle maintenance prompting device, it is unnecessary to additionally arranging a gyroscope and an engine rotating speed sensor, and relative data for calculating vehicle speed can be obtained by utilizing the CAN bus communication module, so that a structure of the vehicle maintenance prompting device is simplified, and cost is reduced.
Description
Technical field
The utility model relates to a kind of vehicle maintenance reminding device.
Background technology
The Chinese patent document of CN201890192 has disclosed a kind of vehicle maintenance reminding device, comprise microprocessor, memory device, gyroscope, velocity pulse module, voltage module, display control circuit and display panel, microprocessor is connected with memory device, gyroscope, velocity pulse module respectively, and microprocessor is connected with display panel by display control circuit.
Microprocessor receives the electrical signal information from gyroscope, velocity pulse module, and calculate the automobile accumulative total milimeter number that travels according to this data message, receive the time electrical signal data information from clock chip simultaneously, by memory device, carry out data maintenance and refresh; In memory device, preserve maintenance warning and the setting value parameter of milimeter number under reminding, when travel milimeter number or Time of Day reach the setting value that maintenance reminds, microprocessor is triggered, and controls display panel display alarm information.
Above scheme, when calculating the speed of a motor vehicle, rely on gyroscope and velocity pulse module, and velocity pulse module is the output of engine speed sensor, owing to not considering transmission device, so what calculate is not actual vehicle speed.
Utility model content
The purpose of this utility model is to provide a kind of vehicle maintenance reminding device, in order to solve prior art due to the data deficiencies of collecting, can not measure the problem of the time speed of a motor vehicle.
For achieving the above object, scheme of the present utility model is: a kind of vehicle maintenance reminding device, comprise microprocessor, memory device, telltale, time meter and CAN bus communication module, described microprocessor connected storage, time meter and CAN bus communication module, output control linkage described in telltale.
Described time meter is timing chip.
Due to the direct various control conveniences of the CAN bus on vehicle, comprise main motor ECU, electrical generator ECU, Engine ECU, instrument, ABS, ECAS etc., so the utility model can not only can collection calculate to base ratio, change speed gear box transmitting ratio, base ratio the various data that rear-end ratio is relevant by CAN communication module, but also can directly obtain the impulse singla that engine speed sensor is exported, thereby calculate actual vehicle speed, and then realize maintenance prompting.So the utility model does not need additionally to increase gyroscope, engine speed sensor, only need can obtain the related data that the speed of a motor vehicle is calculated by CAN communication module, simplified the structure of vehicle maintenance reminding device, reduced cost.
Accompanying drawing explanation
Fig. 1 is structured flowchart of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in more detail.
A kind of vehicle maintenance reminding device as shown in Figure 1, comprises microprocessor, memory device, telltale, time meter and CAN bus communication module, microprocessor connected storage, time meter and CAN bus communication module, output control linkage described in telltale.Telltale can adopt the read-out of read out instrument on existing vehicle, also can adopt special-purpose display equipment.Time meter is timing chip.
Main improvement of the present utility model is directly to obtain engine impulse information and the various transmission information relevant to vehicle speed measurement by CAN bus communication module, so the speed of a motor vehicle and the travelled distance that calculate are also more accurate.About how, by transmission information and the engine impulse calculated signals speed of a motor vehicle and travelled distance, belong to routine techniques, do not repeat them here.
In the process of Vehicle Driving Cycle, CAN bus communication module can receive the speed of a motor vehicle message that CAN bus sends always, and this message calculates the mileage of Vehicle Driving Cycle through microprocessor, and meanwhile, microprocessor can calculate the service time of vehicle.Maintenance content is by judging that travelled distance and the service time of vehicle determines whether the region of interest of vehicle needs maintenance.For example transmission center cross 3 months or the 20000 kilometers of needs that travel are lubricated, as long as these two conditions have one of them to meet, it is transmission center cross that electronic vehicle maintenance assistant will point out driver to maintain position, and maintenance content is lubricated.Before driver checks emm message, electronic vehicle maintenance assistant's button can glimmer always, after driver checks, clicks reset button, and emm message can be clear, and the assistant of electronic vehicle maintenance simultaneously gives tacit consent to the representative that resets and need to maintain to such an extent that position has been maintained complete.
According to tyre model, can find vehicle and select the rear-end ratio of tire, the theoretical running radius of tire of tire, the pulse count simultaneously circling according to output shaft of gear-box is 8, and sensor transmitting ratio is 1 can calculate theoretical velocity ratio.In actual vehicle speed, be for example 40KM/H, the speed ratio that mileage calculation module is set and actual theory are that the speed ratio of setting calculates, 40 * (setting speed ratio/theoretical velocity ratio), can find out that speed meter is all accurate at last, if inaccurate, adjust to set speed ratio value until speed of a motor vehicle accurate location, mileage calculation module is carried out integration to the speed of a motor vehicle can calculate Vehicle-Miles of Travel data.
What timing chip adopted is the RX-8025 chip that EPSON company produces, it is a kind of chip of real-time timing, by the adjustable 37.768khz quartz crystal of its built-in high precision, there is interruption generating function, vibration stops measuring ability, supply voltage monitoring measuring ability and clock accuracy are adjusted function, can bring into operation by sart fire judgement vehicle on vehicle, according to vehicle, disconnect the operation of on fire judgement vehicle stop simultaneously, calculate the time of a vehicle operating, Time Calculation module is by the total time of vehicle each run Time Calculation vehicle operating, judgement data are provided to maintenance vehicle processing module, judge whether vehicle meets temporal maintenance condition.
Vehicle maintenance reminding device can judge whether vehicle needs maintenance from time and travelled distance two aspects simultaneously, and service time interval and service cycle interval, which condition first meets, and just usings which condition as basis for estimation, all can remind driver need to maintain to obtain position and maintenance procedure.There are the position of emphasis maintenance in transmission shaft cross axle, transmission shaft flange yoke, storage battery, engine assembly, air filtering core, magnetic clutch, withdrawal bearing, back axle assembly, hub bearing, steering assembly, power steerig pump, 12 traditional vehicle of fire extinguisher and the position that main drive motor system, generator system, 3 new forms of energy car new forms of energy part emphasis of motor three-phase electricity cable maintain in maintenance position.All maintenance division of teaching contents become driving system emm message, driving system emm message, steering swivel system emm message, brake system emm message, electric system emm message and other system emm message.
The utility model can allow vehicle be maintained timely, in servicing operations, can get rid of the wearing and tearing that may occur or the position of fault, avoid vehicle because maintaining other performance that causes not in time unnecessary wearing and tearing or affect vehicle, improve the safety factor of vehicle, reduce the service expenditure of vehicle, extend the period of service of vehicle.
