Abstract
The invention relates to the field of automobiles, in particular to a cruise control system of an automobile. The cruise control system comprises a signal acquisition module, a control module and an output execution module, wherein the signal acquisition module is connected with the control module which is connected with the output execution module and comprises an SMD (Surface Mounted Device) type MEGA8L singlechip, and the signal acquisition module comprises an automobile speed sensor. With the adoption of the scheme, a cruise control switch is required to be turned on at the beginning, and the automobile speed is stabilized for 2 seconds, so that the cruise control system can perform cruise control automatically.
Description
Technical field
The present invention relates to automotive field, refer in particular to a kind of automobile fixed speed cruise system.
Background technology
Automobile is a kind of very important vehicle in people's daily life, and for a long time during the journey, in order to keep certain speed, chaufeur need stepped on throttle for a long time, and to keep posture constant, causes fatigue easily.
Therefore, the inventor does further research to this, develops a kind of automobile fixed speed cruise system, and this case produces thus.
Summary of the invention
The object of the present invention is to provide a kind of automobile fixed speed cruise system, only need when beginning, open the cruise switch, in 2 seconds of stabilizing speed, the constant speed system can automatic constant speed.
To achieve these goals, technical scheme of the present invention is following:
A kind of automobile fixed speed cruise system comprises signal acquisition module, control module, output execution module; Described signal acquisition module is connected with control module, and control module is connected with the output execution module; Described control module comprises SMD MEGA8L micro controller system, and signal acquisition module comprises car speed sensor.
After adopting such scheme, the present invention compared with prior art has the following advantages:
1, keep automobile driving speed stable.No matter running car still go up a slope at level road, descending, no matter be bright and sunny also or hurricane, as long as in the scope that engine power allows, the moving velocity of automobile all can keep invariable.
2, improve the traveling comfort of running car.Because its speed of a motor vehicle is stable, does not have fast or slow sensation, especially in the countryside or running on expressway, the traveling comfort embodiment that the occupant takes more obvious.In addition, because chaufeur need not frequently be stepped on stepping on accelerator pedal, degree of fatigue can alleviate greatly.
3, can improve the fuel economy and the feature of environmental protection.After adopting cruising constant speed system, can make the supply of engine fuel and cooperating of power be in optimum regime, under same driving conditions,, can save fuel oil 15%, and reduce the content of toxic ingredient in the exhaust for experienced driver.
Description of drawings
Fig. 1 is a scheme drawing of the present invention;
Label declaration
Signal acquisition module 1, control module 2, output execution module 3, air throttle of car 4.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is further described.
A kind of automobile fixed speed cruise system as shown in the figure, that the present invention discloses comprises signal acquisition module 1, control module 2, output execution module 3; Signal acquisition module 1 is connected with control module 2, and control module 2 is connected with output execution module 3; Control module 2 comprises SMD MEGA8L micro controller system, and signal acquisition module 1 comprises car speed sensor.
At first gather the car speed sensor impulse singla through signal acquisition module 1; When signal is delivered to, in the control module 2 after, the fixed speed signal of GES that collects and current setting is compared; And carry out controlled reset through pid algorithm and calculate, draw current controlling quantity.
The current controlling quantity that will calculate through output execution module 3 then changes into pwm pulse output, with these Control of Automobile throttle gate 4 switches, finally confirms car speed.
Above-mentionedly be merely specific embodiment of the present invention, but design concept of the present invention is not limited thereto, allly utilizes this design that the present invention is carried out the change of unsubstantiality, all should belong to the behavior of invading protection domain of the present invention.
