Description
Technical field
The present invention relates to a kind of automotive electronics accessory, related in particular to a kind of automobile GSS Gear Select Switch of the CAN of having communication function.
Background technology
Country supported the development of new forms of energy bus energetically in recent years, and the new forms of energy bus seldom adopts manual transmission, generally adopts driving switch to replace original gear shifting handle.Existing driving switch comprises 3 driving switch, and R, N, D represent reversing, neutral gear respectively, advance, and generally uses industrial interlock switch; Mechanical interlocked mechanism guarantees when a switch is pressed; Other switches can be upspring, and this type construction of switch is simple and reliable, but have some problems.
When 1. traffic safety requires R shelves and D shelves to switch, necessary earlier through the N shelves, and to slam braking.Existing driving switch can't be realized the protection of this respect.
2. traffic safety requires vehicle in motion, cannot press N shelves and R gear switch, and existing driving switch can't be realized the protection of this respect.
3. existing driving switch, its gear signal is passed to other controllers through electric wire, when a plurality of controllers need this signal, can increase the quantity of electric wire, and controller also need increase by 3 input ports and gather gear signal.Driving switch needs the part signal on the car simultaneously, and such as the brake pedal signal, existing corresponding electric wire connects.
4. work as a plurality of controllers applied signal voltage is required not simultaneously, need to increase extra regulating circuit and mate the Different control device.
Summary of the invention
The present invention mainly is the deficiency to prior art, and a kind of automobile GSS Gear Select Switch with CAN communication function of simple to operate, safe ready is provided.
To achieve these goals, the present invention provides following technical scheme:
A kind of automobile GSS Gear Select Switch with CAN communication function; It comprises driving switch button, driving switch controller and lockable mechanism; Said driving switch button comprises that said driving switch button comprises backing car gear switch key, neutral driving switch button, drive shift bit switch button and motion driving switch button; Said driving switch controller comprises a single-chip microcomputer; Said lockable mechanism comprises electromagnet, spring and lock pin, and said locking system is arranged on each said driving switch button.
As a preferred embodiment of the present invention, said backing car gear switch key, neutral driving switch button, drive shift bit switch button and motion driving switch button use respectively to R button, N button, D button and S button and identify identification.
As a preferred embodiment of the present invention, a breach is arranged all on the said driving switch button.
As a preferred embodiment of the present invention, it is the single-chip microcomputer of P80C592 that said driving switch controller has adopted the master chip model.
Can find out that from technique scheme the automobile GSS Gear Select Switch with CAN communication function that the present invention discloses, its utilization driving switch controller are collected and fed back gear information; Send other controllers then to; So not only can avoid the direct switching between the driving switch, prevent the potential safety hazard that the misoperation youngster causes, and the present invention is easy to and other controller butt joints; Need not to increase circuit, reduced the waste of cost and resource.
Description of drawings
Fig. 1 is the structural representation of lockable mechanism one preferred embodiment according to the invention;
Among the 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 set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
Consult Fig. 1, Fig. 1 is the structural representation of lockable mechanism one preferred embodiment according to the invention.
A kind of automobile GSS Gear Select Switch with CAN communication function; It comprises driving switch button 1, driving switch controller and lockable mechanism; Said driving switch button comprises that said driving switch button comprises backing car gear switch key, neutral driving switch button, drive shift bit switch button and motion driving switch button; Said driving switch controller comprises a single-chip microcomputer; Said lockable mechanism comprises electromagnet 2, spring 4 and lock pin 3, and said locking system is arranged on each said driving switch button.
Said backing car gear switch key, neutral driving switch button, drive shift bit switch button and motion driving switch button use respectively to R button, N button, D button and S button and identify identification.
A breach is all arranged on the said driving switch button 1, can let said lock pin 3 be urged in the breach of button, make button to press, can prevent misoperation, and handled easily, fail safe increase; Through control electromagnet 2, can pin driving switch, prevent misoperation, can realize the logic of shifting gears simultaneously; When said electromagnet 2 no powers, under the effect of said spring 4, said lock pin 3 is urged in the breach of button, and this moment, button can't be pressed; When said electromagnet 2 had electricity, electromagnetic force overcame spring force, and said lock pin 3 is drawn onto the left side, leaves the breach of button, and button can be pressed.
It is the single-chip microcomputer of P80C592 that said driving switch controller has adopted the master chip model; Single-chip microcomputer is gathered information such as gear signal, control electromagnet; And pass to other controllers to information through the CAN network; Share gear information with other controllers, the information such as obtaining brake pedal, the speed of a motor vehicle of reentrying; Single-chip microcomputer can feed back the information such as the speed of a motor vehicle on the CAN network, pins driving switch during driving, prevents misoperation.
After automobile key powered on, said gear controller will send to gear information on the CAN, and engine controller is accepted gear information, and only when neutral gear, engine could start; The speed of a motor vehicle is 0, and the driver steps on brake pedal, and D shelves and R shelves are locking not, and the driver can shift gears; After the driver pressed the D shelves, the speed of a motor vehicle was 0 o'clock, and locking reverse gear, the speed of a motor vehicle are not 0 o'clock, and locking reverse gear and neutral gear can be avoided the direct switching between R and the D, press other buttons when avoiding driving a vehicle simultaneously.
The automobile GSS Gear Select Switch that the present invention discloses with CAN communication function; Its utilization driving switch controller is collected and is fed back gear information, sends other controllers then to, so not only can avoid the direct switching between the driving switch; Prevent the potential safety hazard that the misoperation youngster causes; And the present invention is easy to and other controllers dock, and need not to increase circuit, has reduced the waste of cost and resource.
The above; Be merely 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 that the present invention disclosed, and variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.
