Problems solved by technology

When the vehicle is driving in the leftmost or rightmost lane of the road, if the lane markings on the curb side are not clear, or there are objects or shadows from the curb around the lane markings on the curb side, the lane departure warning system may fail. Inspection lane lines, can not provide timely alarm for the driver

Embodiment Construction

[0038] In order to make the object, technical solution and advantages of the present invention clearer, specific embodiments will be described in detail below in conjunction with the accompanying drawings.

[0039] figure 1 It is a processing flowchart of a method for preventing a vehicle from colliding with a curb provided by an embodiment of the present invention. Such as figure 1 As shown, a method for preventing a vehicle from colliding with a curb at least includes steps S102 to S108.

[0040] Step S102, collecting distance signals generated by at least two distance sensors disposed on the same side of the vehicle, reflecting the distance between the vehicle and the curb; collecting vehicle speed signals generated by the vehicle speed sensors.

[0041] Step S104, judge whether the vehicle has a tendency to collide with the curb according to the distance signal, if yes, execute step S106; otherwise, return to step S102.

[0042] Step S106, calculating the estimated time...

Abstract

The invention provides a method and a device for preventing a vehicle from colliding with a road edge. The method comprises the following steps: S1, collecting distance signals for reflecting the distance between the vehicle and the road edge, wherein the distance signals are generated by at least two distance sensors arranged at the same side of the vehicle; acquiring vehicle speed signals generated by a vehicle speed sensor; S2, judging whether the vehicle has a tendency of colliding with the road edge or not according to the distance signals, if yes, executing the step 3; if not, returning to the step 1; S3, calculating estimated time that the vehicle collides with the road edge according to the vehicle speed signals; S4, judging whether the estimated time is greater than a threshold value or not, and if yes, giving an alarm; if not, performing aided driving intervention while the alarm is given. The method and the device provided by the invention aim to prevent the vehicle from colliding with the road edge when the vehicle runs on a left-most or right-most lane.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a method and device for preventing a vehicle from colliding with a roadside. Background technique [0002] Along with the increase of automobile usage, traffic safety is more and more subject to people's attention and attention. In the prior art, in order to prevent the vehicle from deviating from the lane during driving, a lane departure warning system is usually used for detection. The existing lane departure warning system collects road surface images through a camera, and uses digital image processing algorithms to determine whether a driving vehicle deviates from the lane. [0003] Since the existing lane departure warning system judges whether the vehicle deviates from the roadside according to the lane lines in the image, the system has high requirements for the clarity of the lane lines in the road. When the vehicle is driving in the leftmost or rightmost lane of the road, if th...
