Abstract
The invention provides a method for automatic steering indication of a motor vehicle. The method comprises the following steps that (a), a voltage signal proportional to a turning angle of a steering wheel is output through a slide rheostat coaxially arranged with the steering wheel; (b), the voltage signal output through the slide rheostat is converted into a signal of a digital mode through an A/D conversion module; (c), a first preset value and a second preset value are stored in an internal storage of a single-chip microcomputer, when the voltage signal is larger than the first preset value of the internal storage, a starting signal is output, and when the voltage signal is smaller than the second preset value of the internal storage, a stopping signal is output; (d), steering lamps are turned on according to the starting signal and the steering lamps are turned off according to the stopping signal.
Description
Technical field
The present invention relates to detection technique field, refer to especially a kind of motor turning auto instruction method.
Background technology
Existing motor turning indication is all that the deflecting bar of stirring under bearing circle by chaufeur starts steering indicating light, and some chaufeur is forgotten and held steering indicating light when can or turn in lane change, causes unnecessary traffic accident.
Summary of the invention
The present invention proposes a kind of motor turning auto instruction method, solved that chaufeur turns to or forgotten out the problem of steering indicating light during lane change.
Technical scheme of the present invention is achieved in that
A motor turning auto instruction method, comprises the following steps: step (a), by slide rheostat output and the proportional voltage signal of steering wheel angle to the coaxial setting of bearing circle; Step (b), is converted to digital form by A/D modular converter by the voltage signal of slide rheostat output; Step (c), in micro controller system internal register, store the first preset value and the second preset value, when voltage signal is greater than the first preset value of internal register, output actuation signal, when voltage signal is less than the second preset value of internal register, output closing signal; Step (d), lights steering indicating light according to described actuation signal, according to described closing signal, extinguishes steering indicating light.
The invention has the beneficial effects as follows: the size by steering wheel angle judges whether lane change or turns to, and automatically controls the opening and closing of steering indicating light.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the diagram of circuit of motor turning auto instruction method of the present invention.
The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, a kind of motor turning auto instruction method of the present invention, is characterized in that, comprises the following steps: step (a), by slide rheostat output and the proportional voltage signal of steering wheel angle to the coaxial setting of bearing circle; Step (b), is converted to digital form by A/D modular converter by the voltage signal of slide rheostat output; Step (c), in micro controller system internal register, store the first preset value and the second preset value, when voltage signal is greater than the first preset value of internal register, output actuation signal, when voltage signal is less than the second preset value of internal register, output closing signal; Step (d), lights steering indicating light according to described actuation signal, according to described closing signal, extinguishes steering indicating light.
The invention has the beneficial effects as follows: the size by steering wheel angle judges whether lane change or turns to, and automatically controls the opening and closing of steering indicating light.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
