Embodiment Construction

[0026] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings of the embodiments:

[0027] The crossing traffic status prompt system provided by the present invention is as follows: figure 1 As shown, the system framework includes: a high-precision positioning map module, a visual sensor module, a central processing unit module and a human-computer interaction module.

[0028] see figure 2 , the specific data processing is:

[0029] The high-precision positioning map module can provide information such as whether there are traffic lights at the current intersection, the lane position of the vehicle, the type of the left lane of the vehicle, the type of the right lane of the vehicle, and the type of the lane ahead of the lane. The high-precision positioning map module is an existing mature technology, and products from companies such as NavInfo and AutoNavi can be used.

[0030] The vision sensor can pro...

Abstract

The invention discloses a crossing passing state prompt method and system. High-precision map positioning information is fused with visual sensor information, when a vehicle is started, a high precision positioning map module plans a driving track according to a destination set by a driver, before that the vehicle reaches a crossing, a man-machine interaction system forecasts present road information of the crossing, when the vehicle approaches the crossing, a visual sensor identifies the present road information and traffic lamp state of the crossing, the information is fused and then the driver is prompted by the interaction system, and the driver can pass the crossing smoothly.

Description

technical field [0001] The invention relates to the technology in the field of automobile automatic driving, in particular to a technology for accurately and detailedly providing intersection road information and signal light status in automatic driving. Background technique [0002] With the rapid development of urban road construction, the problem of driving vehicles to the correct lane and accurately following the signal lights when driving through the intersection has become increasingly prominent. With the continuous development of automatic assisted driving technology, it is of great significance to accurately identify intersection lights and vehicle traffic status. At present, the conventional navigation can only realize the advance warning of the positions of intersections and signal lights, and has the disadvantages of high error rate and inaccurate vehicle traffic status. [0003] At present, the high-precision map and positioning technology has gradually matured ...
