Description
Technical field
The invention belongs to field of automobile electronic control, more particularly, it relates to which one kind prevents automobile chassis from scraping
Device.
Background technology
At present, with expanding economy, the ownership that the world gets on the car is increasing, while plays and focus in all trades and professions
The effect wanted.Because the requirement of automobile handling, the chassis height of passenger car usually will not be too high, plus many roads not
It is very smooth, especially construction section, often has some zanjons or bump.When vehicle is by these road surfaces, warp
Often chassis and road surface can be not enough caused to scrape because of chassis height, severe patient can cause chassis part to damage and influence vehicle
Performance.
The content of the invention
The purpose of the present invention is to propose to a kind of device for preventing automobile chassis from scraping.
The present invention prevent device that automobile chassis scrapes include control unit, the alarm unit that is connected with control unit and
First distance measuring sensor, first distance measuring sensor are installed on below vehicle front bumper, and ranging direction is front lower towards automobile
Side；When automobile chassis minimum altitude, zero load and the tire pressure that described control unit is pre-stored with extreme condition are in maximum
Automobile chassis maximum height.When the extreme condition is in minimum value for specified maximum load and tire pressure.
When automobile is advanced, the first distance measuring sensor detects its distance with ground, and the range information is sent to control
Unit processed, control unit are scraped according to the range information and pre-stored automobile chassis height to determine whether chassis can occur,
And it will determine that result sends related prompting by alarm unit to driver.Since automobile chassis is highly possible to doughnut
Pressure, carload situation and change, therefore pre-stored automobile chassis is highly including at least the automobile bottom under extreme condition
Disk minimum altitude, zero load and tire pressure are in automobile chassis maximum height during maximum, if the first distance measuring sensor and ground
Distance is less than automobile chassis minimum altitude, then is certain to that chassis scraping occurs, if the distance on the first distance measuring sensor and ground exists
Between automobile chassis minimum altitude and automobile chassis maximum height, it is likely that chassis occurs and scrapes, if the first ranging passes
The distance on sensor and ground is more than automobile chassis maximum height, then chassis scraping will not occur certainly, alarm unit is according to above-mentioned
Three kinds of situations send different information warnings.
Further, to ensure that ranging is accurate, described control unit is also associated with least two second distance measuring sensors, institute
State the second distance measuring sensor to be installed at the threshold of chassis lower part both sides, ranging direction is towards automobile front lower place；The control is single
Member is also associated with the 3rd distance measuring sensor, and the 3rd distance measuring sensor is installed on the front lower portion of automobile front longitudinal beam, ranging side
To towards automobile front lower place；Described control unit is also associated with the 4th distance measuring sensor, and the 4th distance measuring sensor is installed on
The rear end lower of automobile front longitudinal beam, ranging direction is towards automobile front lower place.
Further, described control unit is connected with vehicle speed sensor.Control unit can not only judge according to speed
The time of chassis scraping may occur, referred to for driver, each ranging sensing can also be turned on and off automatically according to speed
Device, after speed is higher than some particular value, that is, closes each distance measuring sensor.
Further, described control unit is equipped with controlling switch, and the controlling switch is arranged in car steering room, driver
Each distance measuring sensor can be voluntarily turned on and off according to actual conditions.
Further, the alarm unit is made of display and loudspeaker, so can not only be carried out by loudspeaker
Alarm, can also show specific range information by display, be referred to for driver.
The present invention's prevents that the apparatus structure that automobile chassis scrapes is simple, easy to control, can effectively measure in real time
Vehicle chassis severe road surface passability, so as to avoid the scraping of automobile chassis and road surface and cause chassis part to be damaged.
Brief description of the drawings
Attached drawing 1 is the schematic diagram of the device for preventing automobile chassis scraping of the present invention.
Embodiment
Below against attached drawing, by the description to embodiment, for example involved to the embodiment of the present invention is each
Mutual alignment and connection relation, the effect of each several part and operation principle between the shape of component, construction, each several part etc. are made into one
The detailed description of step.
Embodiment 1：
As shown in Figure 1, the present embodiment prevent automobile chassis scrape device include control unit 1, with control unit phase
2 and first distance measuring sensor 3 of alarm unit even, at least two second distance measuring sensors 4, the 3rd distance measuring sensor the 5, the 4th are surveyed
Away from sensor 6, wherein the first distance measuring sensor 3 is installed on below vehicle front bumper, the second distance measuring sensor 4 is installed on chassis
At the threshold of lower part both sides, the 3rd distance measuring sensor 5 is installed on the front lower portion of automobile front longitudinal beam, and the 4th distance measuring sensor 6 is pacified
Rear end lower loaded on automobile front longitudinal beam, the ranging direction of each distance measuring sensor is towards automobile front lower place；Control unit 1 is pre-
It is stored with specified maximum load and when automobile chassis minimum altitude, zero load and tire pressure when tire pressure is in minimum value are in maximum
Automobile chassis maximum height.
Further, control unit 1 is also associated with vehicle speed sensor 7.Control unit 1 can judge possibility according to speed
Occur the time that chassis scrapes, to refer to for driver, each distance measuring sensor can also be turned on and off automatically according to speed, when
After speed is higher than some particular value, that is, close each distance measuring sensor.
Further, alarm unit 2 is made of display 21 and loudspeaker 22, so not only can by loudspeaker 22 into
Row alarm, can also show specific range information by display 21, be referred to for driver.
When automobile is advanced, each distance measuring sensor detects its distance with ground, and the range information is sent to control
The distance on unit 1, each distance measuring sensor of 1 Integrated comparative of control unit and ground, and draw the ground clearance of minimum, according to this
Minimum ground clearance and pre-stored automobile chassis height are to determine whether can occur chassis scraping, and will determine that result passes through
Alarm unit 2 sends related prompting to driver.
If minimum ground clearance is less than automobile chassis minimum altitude, it is certain to that chassis scraping occurs；If it is minimum from
Ground distance is between automobile chassis minimum altitude and automobile chassis maximum height, it is likely that occur chassis scrape, it is necessary to
Driver checks in person；If minimum ground clearance is more than automobile chassis maximum height, chassis scraping will not occur certainly；It is alert
Show that unit 2 sends different information warnings according to above-mentioned three kinds of situations.
