Abstract
An automobile rotating speed regulating system comprises a single-chip microcomputer as well as a four-position knob switch, a memory button, a rotating speed increase button, a rotating speed decrease button, a shutoff button and a manual accelerator button which are connected to the single-chip microcomputer, wherein the single-chip microcomputer is connected to an instrument and a vehicle ECU (electronic control unit) through a CAN (controller area network) communication module. Through limitation of the rotating speed value of an engine, the single-chip microcomputer enables the ECU to control the fuel injection quantity of the engine through a CAN bus so as to control the rotating speed of the engine within a required rotating speed value stably and provide continuous power for an assembly system safely and efficiently. The idle speed of the engine can be regulated to a reasonable value conveniently by regulation of the idle speed of the engine. Through the limitation of the rotating speed of the engine, the maximum rotating speed of the engine can be regulated, so that dangerous conditions caused by over-high rotating speeds can be avoided. During the rotating speed regulation, the single-chip microcomputer sends rotating speed regulation information to the instrument through the CAN communication module to facilitate the display of corresponding operation results by the instrument, so that the usage safety factor is improved.
Description
Technical field
The utility model relates to automobile control technology field, is specifically related to a kind of automobile rotational speed adjustment System.
Background technology
Engineering truck is the trunk strength of building engineering industry, doubles because their appearance makes the progress of building engineering, has greatly reduced manpower.In a lot of application, need engine running under a certain constant rotational speed, to provide power for the rear dress engineer operation system of vehicle.Existing speed governing system is to adjust manual accelerator by chaufeur at outdoor manual to carry out control engine rotating speed mostly, and precision is lower, and does not adopt other technologies measure to avoid excessive speeds, likely causes dangerous situation to occur.
Summary of the invention
The utility model, in order to overcome the deficiency of above technology, provides one to realize constant engine speed running, and the automobile rotational speed adjustment System of continuous driving force is provided for upper assembling system safely and efficiently.
The utility model overcomes the technical scheme that its technical matters adopts:
This automobile rotational speed adjustment System, comprises micro controller system; Four position rotor switchs, memory button, the rotating speed that is connected in micro controller system increases button, rotating speed subtracts button, X button and hang throttle button, described micro controller system is connected in instrument and vehicle ECU by CAN communication module, and four positions of described four position rotor switchs respectively corresponding engine idle adjustment gear, engine speed limit value arrange gear, engine speed adjustment gear and outdoor manual accelerator adjustment of rotational speed gear.
The beneficial effects of the utility model are: by the restriction to engine speed value, can make micro controller system make ECU control engine fuel charge reach tachometer value that control engine stabilization of speed operates at requirement safely and efficiently for upper assembling system provides continuous driving force by CAN bus.Utilize engine idle adjustment, can conveniently engine idle be adjusted to reasonable numerical value.Arrange by engine speed limit value, can adjust the maximum speed of revolution of driving engine, avoid excessive speeds, cause the generation of dangerous situation.In the time carrying out adjustment of rotational speed, micro controller system utilizes CAN communication module to send adjustment of rotational speed information to instrument, and to facilitate instrument to show corresponding operating result, chaufeur is in operation, can know clearly very much current adjustment modes and adjustment value, improve the safety factor using.
Brief description of the drawings
Fig. 1 is structural principle block diagram of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing 1, the utility model is described further.
This automobile rotational speed adjustment System, comprises micro controller system; Four position rotor switchs, memory button, the rotating speed that is connected in micro controller system increases button, rotating speed subtracts button, X button and hang throttle button, and described micro controller system is connected in instrument and vehicle ECU by CAN communication module.Four position knobs can be distinguished corresponding engine idle adjustment, the setting of engine speed limit value, engine speed adjustment and four gears of outdoor manual accelerator adjustment of rotational speed.
Four position rotor switchs are threaded to engine idle adjustment, under idling mode, can increase button, rotating speed and subtract button by micro controller system processing by pressing rotating speed, utilize CAN bus communication module and ECU communication after processing, ECU synchronously increases or reduces engine speed.Press after memory button, the engine speed value of micro controller system memory current request and recover the rotational speed limit of preserving last time, and to utilize CAN bus communication module to make ECU keep engine speed be setting value.
Four position rotor switchs are threaded to the setting of engine speed limit value, are ensureing that engine speed, in controlled range, can carry out limit value control to engine speed, its acquiescence limit value is 1800rpm.Can increase button, rotating speed and subtract button and increase or reduce engine speed limit value by pressing rotating speed, micro controller system can make to be limited to setting value on the rotating speed of driving engine by CAN bus communication module control ECU.Can remember current engine speed limit value and recover the rotational speed limit of preserving last time by pressing memory button.
Engine speed limit value setting up procedure can show by instrument, in the time four position rotor switchs be threaded to engine speed limit value arrange, micro controller system starts flickering display " engine speed limit value arranges XXrpm " by CAN bus communication module control instrument, represent that preparing to enter rotational speed limit arranges pattern, chaufeur can increase button by pressing rotating speed, rotating speed subtracts button and enters adjustment of rotational speed pattern, and regulate, instrument shows " engine speed limit value arranges XXrpm " simultaneously.XX is the rotating speed of target limit value that will arrange.
Four position rotor switchs are threaded to engine speed adjustment, and the rotating speed that now can shut by Multifunction open increases button, rotating speed subtracts button, and utilizing micro controller system to pass through CAN bus communication module control ECU increases or reduce engine speed.By pressing the memory button engine speed value that can remember current request and the rotating speed value request that recovers to preserve last time.Engine speed adjustment value is subject to engine speed limit value the restriction that keeps off the rotational speed limit of setting is set.Engine speed adjustment process can show by instrument, when each condition meets, when adjustment of rotational speed switch is placed in engine speed adjustment, instrument starts flickering display " engine speed is adjusted XXrpm ", represent to prepare to enter adjustment of rotational speed pattern, chaufeur can increase button by rotating speed, rotating speed subtracts button and enters adjustment of rotational speed pattern, and regulates, and micro controller system shows " engine speed is adjusted XXrpm " by CAN bus communication module control instrument simultaneously.XX is adjustment aim tachometer value.When chaufeur is pressed X button, engine speed adjustment modes exits.
Four position rotor switchs are threaded to outdoor manual accelerator adjustment of rotational speed, turn manual accelerator knob, micro controller system opponent throttle signal utilizes ECU to adjust engine speed by CAN bus communication module after processing.Manual accelerator engine speed adjustment value is subject to equally engine speed limit value a grade restriction for the rotational speed limit of setting is set.
