Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings.

[0016] The corner meeting scene described in the present invention is as attached figure 1 shown. The meeting reminder system arranges a road test unit (1) on the side of the curve, and arranges an on-board unit (2) on the top of the center of the vehicle, and obtains relevant information through communication between the road test unit and the on-board unit.

[0017] The flow of the present invention's prompting method for meeting cars in blind spots on highway curves is in accordance with the appended figure 2 shown. First, the camera at the middle position in front of the vehicle is used to detect the lane line of the road ahead. If there is a curve, it will judge the turning of the curve. The OBU releases the road information ahead obtained by the vehicle vision system. If the measured distance between OBUs is less than a certain threshold, it indicates that th...

Abstract

The invention discloses a meeting prompting method for a curve blind area, which relates to the field of vehicle safety, in order to overcome the defect that an existing convex mirror curve blind areameeting prompting method is prone to being affected by severe weather, driving of a driver is influenced by mirror reflection, and other methods adopting radar or visual detection cannot correctly prompt the curve road condition, especially under the condition that a blind area exists due to barrier shielding. The invention provides a curve blind area meeting prompting method based on vision andV2X. Front road information is detected through a vehicle-mounted visual system, a road test unit receives vehicle information and measures the distance with the vehicle, the vehicle in a curve is screened out, whether meeting occurs or not is judged according to turning information of the curve in front of the vehicle, and when meeting is judged to be about to occur, prompting information is sentout. The method is not influenced by external conditions such as weather, illumination, road conditions, front vehicle shielding and the like, and accurate meeting prompting information can be givenat the curve.

Description

technical field [0001] The invention relates to a vehicle meeting warning method, in particular to a vehicle meeting warning method at a curve where there is a blind spot blocked by an obstacle. Background technique [0002] At present, the safety reminder measures used to meet cars on curves are mainly to arrange a convex mirror at the intersection of the curve. The driver can observe whether there is a vehicle approaching in the blind area through the convex mirror. Inclement weather, and the reflected light from the convex mirror at night may dazzle oncoming drivers. The rest of the warning methods, such as the radar or visual detection method used in the more commonly used vehicle forward collision warning technology, can only measure the straight-line distance between the vehicle and the vehicle in front, so it has a better warning prompt for vehicles on the straight road. However, for curved road conditions, especially when there are obstacles and blind spots, the veh...
