Abstract
The utility model relates to the field of automobiles, in particular to an automobile constant speed cruise system. The automobile constant speed cruise system comprises a signal acquisition module, a control module, and an output execution module. The signal acquisition module is connected with the control module and the control module is connected with the output execution module. The control module comprises a surface mounted device type MEGA8L single chip microcomputer and the signal acquisition module comprises a vehicle speed sensor. By means of the scheme, a constant speed cruise switch can be turned on merely at the beginning and automobile speed can be stabilized in two seconds, and then the constant speed system can achieve automatic constant speed.
Description
Technical field
The utility model relates to automotive field, refers 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 to stepped on throttle for a long time, and to keep posture constant, easily causes fatigue.
Therefore, the inventor makes further research this, develops a kind of automobile fixed speed cruise system, and this case produces thus.
The utility model content
The purpose of this utility model is to provide a kind of automobile fixed speed cruise system, only needs open when beginning the cruise switch, and in 2 seconds of stabilizing speed, the constant speed system can automatic constant speed.
To achieve these goals, the technical solution of the utility model is as follows:
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 utility model 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, without fast or slow sensation, especially in the countryside or running on expressway, it is more obvious that the traveling comfort of passenger riding embodies.In addition, because chaufeur need not frequently be stepped on stepping on accelerator pedal, degree of fatigue can alleviate greatly.
3, can improve 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, for experienced chaufeur, can save fuel oil 15%, and reduce the content of toxic ingredient in the exhaust.
Description of drawings
Fig. 1 is schematic diagram of the present utility model;
Label declaration
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described.
As shown in the figure, a kind of automobile fixed speed cruise system that the utility model 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 by signal acquisition module 1, when signal is delivered to, in the control module 2 after, the vehicle speed signal that collects and the fixed speed signal of current setting are compared, and carry out controlled reset by pid algorithm and calculate, draw current controlling quantity.
The current controlling quantity that then will calculate by output execution module 3 changes into pwm pulse output, controls air throttle of car 4 switches with this, finally determines car speed.
Above-mentioned only is specific embodiment of the utility model, but design concept of the present utility model is not limited to this, allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
