Embodiment Construction

[0034] Below, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of not conflicting, the various embodiments described below or the technical features can be combined arbitrarily to form new embodiments. .

[0035] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or there can also be an intervening component. When a component is said to be "connected" to another component, it may be directly connected to the other component or there may be intervening components at the same time. When a component is said to be "set on" another component, it may be set directly on the other component or there may be an intervening component at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only.

Abstract

The invention discloses a safety guarantee method for automatic driving vehicles in rainy days. A camera obtains a real-time image of a windshield, a light-responsive rain sensor collects the rain of the windshield and generates sensory rain data; a control unit receives the real-time image of the windshield. image, and filter out raindrop images with smooth edges, ignore invalid raindrop images, and analyze and generate camera rainfall data in real time; the control unit analyzes the sensory rainfall data and camera rainfall data to obtain real-time rainfall grades; the safe speed of the vehicle. The rain level is identified through the fusion of the camera and the photoreactive rain sensor, and a peer-to-peer relationship is established between the two to ensure that in a rainy environment, the perception ability of the vehicle is estimated according to the rain level detected by the rain sensor, so the maximum driving safety is limited. The speed of the vehicle ensures that the vehicle can accurately identify obstacles and ensure driving safety.

Description

technical field [0001] The present invention relates to the field of automatic driving, and in particular to a safety guarantee system and method for driving an automatic driving vehicle in rainy weather. Background technique [0002] At present, with the rapid development of society, more and more cars have entered people's daily work and life, and people's demand for cars has also increased, and research on unmanned driving has gradually deepened. [0003] Patent Document 1 (Application No. CN201210427353) discloses a variable speed limit control system and method for highways in rainy weather, including vehicle detectors, rain gauges, variable speed limit signs and overspeed capture systems. The traffic control machine is used to receive and judge the dynamic bottleneck road section according to the traffic flow detected by the vehicle detector and the rainfall measured by the rain gauge, using the quadratic programming algorithm of nonlinear programming and combining the...
