Abstract
The invention discloses an automobile electronic accessory and particularly relates to an automobile gear selection switch with a CAN communication function, which comprises gear switch buttons, a gear switch controller and locking mechanisms, wherein the gear switch buttons comprise a reverse gear switch button, a neutral gear switch button, a drive gear switch button and a sport gear switch button, the gear switch controller includes a single chip microcomputer, each locking mechanism comprises an electromagnet, a spring and a lockpin, and each gear switch buttons is provided with one locking mechanism. The automobile gear selection switch with the CAN communication function can not only avoid direct switchover between gear switches and prevent faulty switching but also be connected with other controllers easily without addition of circuits so as to reduce cost and waste of energy.
Description
Technical field
The present invention relates to a kind of automotive electronics accessory, particularly relate to a kind of automobile gears selector switch with CAN communication function.
Background technology
Country supported that new forms of energy bus developed energetically in recent years, and new forms of energy bus seldom adopts manual transmission, and the general driving switch that adopts replaces original gear shifting handle.Existing driving switch comprises 3 driving switch, and R, N, D represent reversing, neutral gear, advance respectively, generally uses industrial interlock switch, mechanical interlocking mechanism ensures when a switch is pressed, other switches can be upspring, and this kind of construction of switch is simple and reliable, but there are some problems.
1., when traffic safety requires that R shelves and D shelves switch, first through N shelves, and braking to must be slammed.Existing driving switch cannot realize the protection of this respect.
2. traffic safety requires vehicle in motion, and cannot press N shelves and R gear switch, existing driving switch cannot realize the protection of this respect.
3. existing driving switch, its gear signal passes to other controllers by electric wire, when multiple controller needs this signal, can increase the quantity of electric wire, and controller also needs increase by 3 input ports to gather gear signal.Driving switch needs the part signal on car simultaneously, such as brake pedal signal, and existing corresponding electric wire connects.
4., when multiple controller requires different to applied signal voltage, need to increase extra regulating circuit to mate different controllers.
Summary of the invention
The present invention, mainly for the deficiencies in the prior art, provides a kind of automobile gears selector switch with CAN communication function of simple to operate, safe ready.
To achieve these goals, the invention provides following technical scheme:
A kind of automobile gears selector switch with CAN communication function, it comprises driving switch button, driving switch controller and lockable mechanism, described driving switch button comprises described driving switch button and comprises backing car gear switch key, neutral driving switch button, drive shift bit switch button and motion driving switch button, described driving switch controller comprises a single-chip microcomputer, described lockable mechanism comprises electromagnet, spring and lock pin, and described locking system is arranged on each described driving switch button.
As a preferred embodiment of the present invention, described backing car gear switch key, neutral driving switch button, drive shift bit switch button and motion driving switch button identify with carrying out mark for R button, N button, D button and S button respectively.
As a preferred embodiment of the present invention, described driving switch button all there is a breach.
As a preferred embodiment of the present invention, described driving switch controller have employed the single-chip microcomputer that master chip model is P80C592.
As can be seen from technique scheme, the automobile gears selector switch with CAN communication function that the present invention discloses, it uses driving switch controller collect and feed back gear information, then other controllers are sent to, so not only can avoid the direct switching between driving switch, prevent the potential safety hazard that misoperation youngster causes, and the present invention is easy to dock with other controllers, without the need to increasing circuit, decrease the waste of cost and resource.
Accompanying drawing explanation
Fig. 1 is the structural representation of lockable mechanism one of the present invention preferred embodiment;
In figure: 1, driving switch button, 2, electromagnet, 3, lock pin, 4, spring.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Consult Fig. 1, Fig. 1 is the structural representation of lockable mechanism one of the present invention preferred embodiment.
A kind of automobile gears selector switch with CAN communication function, it comprises driving switch button 1, driving switch controller and lockable mechanism, described driving switch button comprises described driving switch button and comprises backing car gear switch key, neutral driving switch button, drive shift bit switch button and motion driving switch button, described driving switch controller comprises a single-chip microcomputer, described lockable mechanism comprises electromagnet 2, spring 4 and lock pin 3, and described locking system is arranged on each described driving switch button.
Described backing car gear switch key, neutral driving switch button, drive shift bit switch button and motion driving switch button identify with carrying out mark for R button, N button, D button and S button respectively.
Described driving switch button 1 all has a breach, described lock pin 3 can be allowed to be pushed in the breach of button, button cannot be pressed, can misoperation be prevented, and handled easily, fail safe increase; By controlling electromagnet 2, can driving switch be pinned, prevent misoperation, logic of shifting gears can be realized simultaneously; When described electromagnet 2 no power, under the effect of described spring 4, described lock pin 3 is pushed in the breach of button, and now button cannot be pressed; When described electromagnet 2 has electricity, electromagnetic force overcomes spring force, and described lock pin 3 is drawn onto the left side, leaves the breach of button, and button can be pressed.
Described driving switch controller have employed the single-chip microcomputer that master chip model is P80C592, single-chip microcomputer is to informations such as gear signal, control electromagnet, and by CAN network, information is passed to other controllers, share gear information with other controllers, reentry and obtain the information such as brake pedal, the speed of a motor vehicle; Single-chip microcomputer can feed back the information such as the speed of a motor vehicle in CAN network, pins driving switch, prevent misoperation during driving.
After automobile key powers on, described gear controller will be sent on CAN gear information, and engine controller accepts gear information, and only when neutral gear, engine could start; The speed of a motor vehicle is 0, and driver steps on brake pedal, D shelves and R shelves not locking, and driver can shift gears; After driver presses D shelves, when the speed of a motor vehicle is 0, locking reverse gear, when the speed of a motor vehicle is not 0, locking reverse gear and neutral gear, can avoid the direct switching between R and D, avoids pressing other buttons during driving simultaneously.
The automobile gears selector switch with CAN communication function that the present invention discloses, it uses driving switch controller collect and feed back gear information, then other controllers are sent to, so not only can avoid the direct switching between driving switch, prevent the potential safety hazard that misoperation youngster causes, and the present invention is easy to dock with other controllers, without the need to increasing circuit, decreases the waste of cost and resource.
The above; be only the embodiment of the preferred embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by the present invention; the change can expected without creative work or replacement, all should be encompassed within protection scope of the present invention.
