The automobile-gear judging device disclosed by the utility model has the advantage that the gears can be displayed.
Description
Technical field
The utility model relates to the automobile shift decision maker.
Background technology
Manual car comprises that five forward, 1 neutral and 1 reverses gear.Do not have the automobile shift Presentation Function on the gauge panel of automobile at present, automobile driver is easily forgotten gear, the especially new hand that oneself is hung in steering vehicle, in a rush phenomenon easily occurs.
The utility model content
The technical problems to be solved in the utility model is that a kind of automobile shift decision maker that can show gear is provided.
Technical solution of the present utility model is, a kind of automobile shift decision maker with following structure is provided, and comprises micro controller system, power circuit and display circuit; Described micro controller system is connected with reversing automobile switch, automobile neutral position switch, automobile rotating speed sensor and car speed sensor; Described micro controller system also is connected with display circuit; Described power circuit is connected with automotive battery, and described power circuit also is connected with micro controller system.
After adopting above structure, automobile shift decision maker of the present utility model compared with prior art, has the following advantages:
When automobile suspension reverses gear, the reversing automobile switch is just closed, and micro controller system just detects reversing information, and micro controller system can be presented at reversing information on the display circuit, when the automobile suspension neutral, the automobile neutral position switch is just closed, and micro controller system just detects neutral information, and micro controller system can be presented at neutral information on the display circuit, when the automobile suspension forward gear, micro controller system can calculate gear according to the speed of a motor vehicle and engine speed, the gear that calculates can be presented on the display circuit, and the mode that the speed of a motor vehicle is calculated gear is:
, wherein i is the change speed gear box transmitting ratio, and n is engine speed (r/min), and I is rear-axle gear ratio, and PI is π, and r is tire radius (m), and v is the speed of a motor vehicle (km/h); By calculating the value of change speed gear box transmitting ratio i, inquiry change speed gear box gear transmitting ratio, automobile shift just can show like this, read-out in the display circuit is located in the automobile instrument panel, just can watch the instruments when forgetting the gear of oneself the hanging gear of the interior demonstration of dish of automobile driver just can, avoid occurring in a rush phenomenon, improve the safety of driving.
