Description
Technical Field
The invention belongs to a vehicle speed alarm technology, and particularly relates to an overspeed alarm method based on an automobile instrument.
Background
At present, the safe driving of the automobile is more and more emphasized, and particularly, serious traffic accidents are often brought about when the automobile runs at an overspeed. At present at the automobile driving in-process, there are the signboard of roadside, have measures such as speed limit sign to the warning of speed of a motor vehicle, however, to vehicle self function, only under the condition that has the navigation, just can alternate there is the pronunciation speed of a motor vehicle limit to remind, reports driver's vehicle and exceeds a speed limit.
Therefore, the existing vehicle speed alarm has the following defects:
for a vehicle without navigation: the speed limit signboard needs to shift a visual angle to observe, so that potential safety hazards exist, and the defects that the position of the speed limit guideboard is uncertain, the number of the speed limit guideboards is not large, and the overspeed of a vehicle cannot be alarmed exist.
Secondly, for the vehicle with navigation:
1. because the voice navigation also comprises the vehicle driving direction and road condition information, the vehicle speed limiting information can not be intercepted in time often. 2. The method has influence on drivers with poor hearing, noisy environment, and voice navigation broadcasting in modes of listening to songs, broadcasting and the like. 3. The overspeed cannot be alarmed at any moment.
Disclosure of Invention
The invention aims to solve the technical problem of providing an overspeed alarm method based on an automobile instrument, which can realize overspeed alarm through a mechanical or liquid crystal instrument under the condition that the road condition is unclear and only the instrument is observed.
In order to solve the technical problems, the invention adopts the following technical scheme:
an overspeed alarm method based on an automobile instrument adopts a mechanical or liquid crystal instrument to perform alarm display, and comprises the following steps:
s1, acquiring current road section speed limit information in real time on a CAN network of a whole vehicle;
s2, comparing the current actual speed with the current actual speed, and judging whether the current overspeed state exists;
s3, according to whether overspeed exists or not, corresponding alarm display is carried out by controlling the color of a pointer of a machine or a liquid crystal instrument;
s4, circulating S1-S4.
In S3: the mechanical instrument is provided with a pointer and a plurality of green and red LED background lamps arranged below the pointer, and when the mechanical instrument judges that the current speed is not over speed, the green LED background lamps are controlled to be lightened, and the pointer is made to be green through a pointer light-transmitting body; and when the current overspeed is judged, the red LED background lamp is controlled to be lightened, and the pointer is made to be red through the pointer light-transmitting body so as to carry out alarm display.
In S3: the liquid crystal instrument is provided with a pointer and a real-time vehicle speed display, and when the liquid crystal instrument judges that the current speed is not overspeed, the pointer and the real-time vehicle speed are controlled to be green; and when the current overspeed is judged, the pointer and the real-time vehicle speed are controlled to be red so as to carry out alarm display.
Further comprising: and when the current road section speed limit information acquired in the S1 and the S2 is abnormal or the current vehicle speed is abnormal, controlling the mechanical or liquid crystal instrument to continue the previous display state.
Compared with the prior art, the overspeed alarm method based on the automobile instrument has the following advantages that:
1. the color display warning function is added on the pointer of the mechanical instrument or the liquid crystal instrument to remind a driver of safe driving;
2. comparing the obtained road speed limit information with the actual speed, and controlling the pointer to present different colors so as to alarm for overspeed;
3. and the real-time vehicle speed colors of the liquid crystal instrument are different, so that overspeed alarm is performed.
Drawings
The invention is described in detail below with reference to the following figures and detailed description:
FIG. 1 is a block flow diagram of a mechanical gauge based overspeed warning method of the present invention;
FIG. 2 is a flow chart diagram of an overspeed warning method based on a liquid crystal instrument of the present invention;
FIGS. 3-4 are graphs showing the non-overspeed and overspeed, respectively, of the mechanical gauge of the present invention;
fig. 5-6 are graphs showing the non-overspeed and overspeed, respectively, of the liquid crystal meter of the present invention.
Detailed Description
The overspeed alarm method based on the automobile instrument, disclosed by the invention, adopts a mechanical or liquid crystal instrument to perform alarm display as shown in figures 1 and 2, and comprises the following steps of:
s1, acquiring current road section speed limit information in real time on a CAN network of a whole vehicle;
s2, comparing the current actual speed with the current actual speed, and judging whether the current overspeed state exists;
s3, according to whether overspeed exists or not, corresponding alarm display is carried out by controlling the color of a pointer of a machine or a liquid crystal instrument;
s4, circulating S1-S4.
Taking a mechanical meter as an example, in S3: the mechanical instrument is provided with a pointer and a plurality of green and red LED background lamps arranged below the pointer, and when the mechanical instrument judges that the current speed is not over speed, the green LED background lamps are controlled to be lightened, and the pointer is made to be green through a pointer light-transmitting body; and when the current overspeed is judged, the red LED background lamp is controlled to be lightened, the pointer is made to be red through the pointer light-transmitting body, and alarm display is carried out through different backlight effects. For example, the speed limit of the current road section is 80km/h, as shown in fig. 3, and the current vehicle speed is measured to be 70km/h, and the current vehicle speed is not overspeed, the pointer 1 points to 70km/h on the instrument panel and is green; as shown in fig. 4, when the current vehicle speed is 110km/h and overspeed is detected, the pointer 1 points to 110km/h on the instrument panel and is red, and overspeed alarm is performed.
Taking a liquid crystal meter as an example, in S3: the liquid crystal instrument is provided with a pointer and a real-time vehicle speed display, and when the liquid crystal instrument judges that the current speed is not overspeed, the pointer and the real-time vehicle speed are controlled to be green; and when the current overspeed is judged, the pointer and the real-time vehicle speed are controlled to be red so as to carry out alarm display. For example, when the speed limit of the current road section is 80km/h, as shown in fig. 5, the pointer 1 points to 70km/h on the instrument panel and is green, and the real-time vehicle speed digital display 2 is also green; as shown in fig. 6, when the pointer 1 points to 110km/h on the instrument panel and is red, and the real-time vehicle speed digital display 2 is also red, overspeed alarm is performed.
In addition, when the current road section speed limit information acquired in S1 and S2 is abnormal or the current vehicle speed is acquired to be abnormal, the mechanical or liquid crystal instrument is controlled to continue the previous display state as an abnormal processing scheme.
In conclusion, the overspeed alarm method based on the automobile instrument can display and warn overspeed driving on the automobile instrument panel at any time, and remind a driver of safer driving, and is more convenient and quicker.
However, those skilled in the art should realize that the above embodiments are illustrative only and not limiting to the present invention, and that changes and modifications to the above described embodiments are intended to fall within the scope of the appended claims, provided they fall within the true spirit of the present invention.
