Specifically, as shown in fig. 2, in the driving process of the user, when the vehicle encounters an abnormal condition, for example, the vehicle passes through a road surface with an obstacle or a road surface protrusion, which cannot be avoided, at this time, the actual speed of the current vehicle needs to be acquired by a speed sensor in the vehicle, so as to determine whether the obstacle exists at the bottom of the vehicle.
In step S102, when the actual vehicle speed is less than the preset vehicle speed, the current vehicle is controlled to enter a chassis obstacle early warning mode, so as to control the detection element to acquire the vertical distance of the obstacle at the bottom of the vehicle.
The preset vehicle speed may be a speed threshold set by a user, or may be a threshold obtained through multiple simulations by a computer, and is not specifically limited herein.
Preferably, the detection member of the embodiment of the application may be a laser radar, and one or more laser radars may be installed in the center of the vehicle chassis for scanning obstacle information of the vehicle chassis, so as to improve detection accuracy.
Specifically, if the actual vehicle speed of the current vehicle is collected to be less than the preset vehicle speed (such as 30 km/h), it is determined that an obstacle exists at the bottom of the vehicle, the laser radar is involved to detect the obstacle at the moment, and the current vehicle is controlled to enter a chassis obstacle early warning mode, so that the situation that the front end of the vehicle can normally pass through and the chassis at the rear end of the vehicle can touch the obstacle due to the problem of the inclination angle of the vehicle when the user passes through the obstacle is avoided, and the economic loss of the user is caused.
Further, in one embodiment of the present application, the controlling the detecting member to collect a vertical distance of an obstacle located at the bottom of the vehicle includes: judging whether the barrier is in a preset area or not; and if the obstacle is in the preset area, acquiring related information of the obstacle, otherwise, disregarding the obstacle.
As shown in fig. 3, the predetermined area is the remaining vehicle area except 4 tires on the entire vehicle chassis.
Furthermore, when the vehicle passes through the obstacle, the data information of the obstacle is scanned through the laser radar, whether the obstacle is in the preset area or not is judged, if the obstacle is in the preset area, the vertical distance between the obstacle and the vehicle chassis is calculated, if the obstacle is not in the preset area, the obstacle cannot touch the vehicle chassis, and at the moment, the data information of the obstacle is removed and the obstacle is ignored, so that the calculation efficiency is improved.
In step S103, a chassis safety distance of the current vehicle is calculated, and when the vertical distance is greater than the chassis safety distance, the current vehicle is controlled to perform a chassis obstacle early warning prompt.
Further, in one embodiment of the present application, calculating a safe distance to the chassis of the current vehicle includes: collecting the whole vehicle mass of the current vehicle; the safe distance of the chassis is matched based on the mass of the whole vehicle.

The vehicle mass may include a vehicle mass and a mass of a front-row user and/or a rear-row user inside the vehicle, and the relational mapping model of the vehicle mass and the safe distance of the vehicle chassis may be set by a person skilled in the art according to models and purposes of different vehicles, which is not specifically limited herein.
Further, a coordinate system is established based on a laser radar in the center of the vehicle chassis, the center of the laser radar is used as a coordinate origin, and the plane of the vehicle chassis is divided into 4 areas by the coordinate system, wherein the areas correspond to 4 quadrants of a coordinate axis respectively; secondly, obstacle data information acquired by the laser radar is fed back to a calculation center of the vehicle, and the angle and the length of the obstacle corresponding to the laser radar can be obtained through the received multiple pieces of feedback information; finally, the coordinate quadrant of the vehicle chassis where the obstacle correspondingly falls can be obtained according to the angle between the obstacle and the laser radar, meanwhile, the specific coordinate information of the x axis and the y axis corresponding to the obstacle can be calculated through a trigonometric function according to the angle between the obstacle and the laser radar, and the coordinate calculation formula is as follows:
X＝L*sinα；
Y＝L*cosα；
wherein, alpha is the angle between the obstacle and the laser radar, and L is the distance length between the obstacle and the laser radar.
Further, after obtaining coordinate information corresponding to the obstacle, the embodiment of the application further determines whether the obstacle is located in a preset area of the vehicle chassis, and if the obstacle is located in the preset area of the vehicle chassis, a linear distance and an angle between the obstacle and the laser radar can be obtained through scanning of the laser radar, and a vertical distance between the obstacle and the vehicle chassis is obtained through a trigonometric function according to the linear distance and the angle, and a calculation formula of the calculation formula is as follows:
H＝L*sinα；
wherein H is the vertical distance between the obstacle and the vehicle chassis.
Further, the obtained vertical distance between the obstacle and the chassis of the vehicle is compared with the safe distance of the chassis of the current vehicle, and if the vertical distance is larger than the safe distance of the chassis, the current vehicle is controlled to carry out early warning prompt on the obstacle of the chassis.
Further, in an embodiment of the present application, controlling the current vehicle to perform a chassis obstacle warning prompt includes: matching the optimal reminding mode according to the vertical distance; and controlling at least one acoustic reminding device and/or at least one optical reminding device of the current vehicle to remind according to the optimal reminding mode.

Specifically, when the vertical distance between the obstacle and the vehicle chassis is greater than or equal to the safe distance between the chassis, at least one acoustic reminding device is matched for reminding, for example, reminding information such as "please pay attention to, the obstacle exists on the vehicle chassis, please drive carefully" is sent to a user through a sound system; when the perpendicular distance of barrier and vehicle chassis is less than chassis safe distance, then indicate that the barrier has the risk of scratching vehicle chassis, can remind this moment through at least one acoustics reminding device and/or at least one optics reminding device, for example, send "notice" to the user through sound system, vehicle chassis has the barrier, and the vehicle angle of having regulated and prudent driving is avoided scraping "and through showing" notice "in the LED display screen, vehicle chassis has the barrier, and the vehicle angle of having regulated and prudent driving is avoided scraping" and so on warning information.
It should be noted that, when there is an obstacle in the vehicle chassis, and an appropriate reminding device is selected according to the vertical distance between the obstacle and the vehicle chassis, for example, the vehicle can be reminded by an acoustic reminding device or an optical reminding device alone, or can be reminded by a combination of the acoustic reminding device and the optical reminding device, which is not limited specifically herein.
Further, in an embodiment of the present application, after controlling the current vehicle to perform the chassis obstacle warning prompt, the method further includes: detecting whether the barrier leaves a preset area or not; and stopping chassis obstacle early warning prompting when the chassis obstacle early warning prompting is detected to leave the preset area.
Specifically, after the current vehicle is controlled to perform chassis obstacle early warning prompting, a user adjusts the vehicle angle through obstacle information detected by the laser radar and the obtained obstacle position, whether the obstacle leaves a preset area or not is detected in real time through the laser radar in the adjustment process, when the obstacle leaves the preset area is detected, the vehicle can be restored to a normal driving state, and at the moment, the chassis obstacle early warning prompting is stopped.
According to the early warning method for the vehicle chassis obstacle provided by the embodiment of the application, when the actual vehicle speed of the current vehicle is acquired to be smaller than the preset vehicle speed, the current vehicle is controlled to enter a chassis obstacle early warning mode so as to control the detection piece to acquire the vertical distance of the obstacle at the bottom of the vehicle and calculate the safe chassis distance of the current vehicle, and when the vertical distance is larger than the safe chassis distance, the current vehicle is controlled to perform chassis obstacle early warning prompt.
