Background
With the development of intelligent technology, in order to ensure safe driving of vehicles and reduce accidents, advanced driving assistance systems (hereinafter referred to as ADAS) are used for more and more automobiles. In order to realize ADAS on the instrument, a large-screen color instrument is often used as the first choice of a host factory and is influenced by the size and the color of a screen, a small-screen monochromatic instrument can only perform some simple ADAS functions such as blind spot monitoring, collision early warning, fatigue driving reminding and the like, and the ADAS comprises a higher part: development of adaptive cruise, lane line assist, and the like is limited.
Therefore, the existing meter ADAS function development has the following disadvantages:
1. in order to realize the ADAS function as much as possible, a color large-screen instrument is selected, so that the cost is high and the development period is long;
2. if a monochromatic small-screen instrument is selected, ADAS development is limited, and only part of simple functions can be developed, such as simple text reminding or alarm signal lamps.
Disclosure of Invention
The invention aims to provide a driving assistance method based on a black-white-gray screen instrument, which can realize a driving assistance function by using the black-white-gray screen instrument and reduce the cost.
In order to solve the technical problems, the invention adopts the following technical scheme:
a driving assistance method based on a black-white-gray screen instrument adopts the black-white-gray screen instrument to perform driving assistance display, and comprises the following steps:
the front vehicle distance is assisted: displaying a front vehicle and a plurality of spaced white vehicle distance lines behind the front vehicle on a black-white-gray screen instrument, and prompting the corresponding front vehicle distance according to the number of the vehicle distance lines and the flashing frequency of the corresponding vehicle distance lines;
lane assistance: and displaying a left lane line and a right lane line on the black-white-gray screen instrument in gray or white to respectively indicate that no lane is detected or a lane is detected, and indicating corresponding lane departure early warning by the flicker frequency of the two white lane lines.
Further comprising: time interval setting is assisted: and thickened short transverse lines are additionally arranged below two ends of the white space lines of the front space display page to represent the set time space.
In the front vehicle time distance assistance, at least four time distance scene displays are set according to the distance of the front vehicle time distance, and the four time distance scene displays are sequentially as follows from far to near: four white space lines and no flicker; three white lane lines, no flicker; two white lane lines and a front lane twinkle at the frequency of 1 HZ; one white lane line and twinkling at a frequency of 2 HZ.
In the lane assistance, at least two deviation scene displays are set according to the lane deviation height, and the deviation scene displays are respectively from low to high: the two white lane lines flash at the frequency of 1 HZ; the two white lane lines flash at a frequency of 2 HZ.
Compared with the prior art, the driving assistance method based on the black-white-grey-screen instrument has the following advantages that:
1. the black-white-gray screen is low in cost compared with a color screen, so that the development period is saved, and the development cost is reduced;
2. the flicker frequency of the grey and white lane lines, the distance lines and the white lines is different to replace the corresponding color lines in the ADAS, so that the ADAS function integrity as a color screen can be realized.
Drawings
The invention is described in detail below with reference to the following figures and detailed description:
FIGS. 1 a-1 d are schematic diagrams of four front vehicle pitch scenarios respectively displayed by the black and white gray screen meter of the present invention;
FIG. 2 is a schematic diagram of the set time interval for the black and white gray screen meter display of the present invention;
fig. 3 a-3 d are schematic diagrams of four lane assist scenarios respectively for the black, white and grey screen instrument display of the present invention.
Detailed Description
The invention relates to a driving auxiliary method based on a black-white-grey screen instrument, which adopts the black-white-grey screen instrument to carry out driving auxiliary display and comprises the following steps:
1. the front vehicle distance is assisted: the display device is characterized in that a front vehicle 2 and a plurality of spaced white vehicle distance lines 3 behind the front vehicle 2 are displayed on a black-white-gray screen instrument 1, the corresponding front vehicle 2 time distance is prompted by the number of the vehicle distance lines 3 and the flashing frequency of the corresponding vehicle distance lines 3, and specifically, as shown in fig. 1 a-1 d, at least four time distance scene displays are set according to the distance of the time distance of the front vehicle 2, and the display is sequentially performed from far to near: four white space lines 3, no flicker; three white lane space lines 3, no flicker; the two white lane distance lines 3 and the front lane twinkle at the frequency of 1 HZ; a white headway line 3 and blinks at a frequency of 2 HZ.
2. Lane assistance: the method comprises the steps of displaying a left lane line 4 and a right lane line 4 on a black-white-gray screen instrument 1 in gray or white to respectively show that no lane is detected or a lane is detected as shown in fig. 3 a-3 b, and displaying corresponding lane departure early warning through the flashing frequency of the two white lane lines 4, wherein at least two departure scene displays can be set according to the lane departure height and are respectively as follows from low to high: as shown in fig. 3c, the two white lane lines 4 blink at a frequency of 1 HZ; as shown in fig. 3d, the two white lane lines 4 blink at a frequency of 2 HZ.
3. Time interval setting is assisted: as shown in fig. 2, thick dash lines 5 are additionally provided under both ends of the several white lane lines 3 on the preceding lane display page to indicate the set time interval.
