Problems solved by technology

It can be seen from the above that the perception and detection of targets by active safety technology is mainly realized by sensors such as on-board cameras or on-board millimeter-wave radars. Under such circumstances, it is easy to be disturbed by the environment, resulting in a decrease in detection accuracy, and it is impossible to ensure that pedestrians and vehicles pass through intersections without signal lights in a safe and efficient manner, which brings great safety hazards to pedestrians and drivers, and may cause unnecessary traffic damage

Embodiment 1

[0034] like Figure 1-Figure 4 As shown, this embodiment provides a method for safely passing through an intersection without signal lights, and the implementation of the method is mainly based on the roadside unit 1 , the vehicle-mounted V2X communication module and the wearable device carried by the pedestrian 2 . Wherein, the wearable device, the vehicle-mounted V2X communication module and the roadside unit 1 are communicatively connected to each other, so that the pedestrian 2 can actively participate in the V2X communication system and realize information exchange with the vehicle 3 . The wearable device mentioned here includes but is not limited to a mobile phone or a watch, and the wearable device is provided with a trigger button or a virtual button, and the wearable device is also provided with an instruction input module. Of course, the wearable device mentioned in this technical solution can also be directly understood as a wearable device equipped with a VRU modul...

Embodiment 2

[0050] like figure 1 and figure 2 As shown, this embodiment discloses an early warning system for safely passing through unsignalized intersections, which is used to implement the method for safely passing through unsignaled intersections mentioned in Embodiment 1, specifically including a roadside unit 1 and a vehicle-mounted V2X communication module. And the wearable device carried by pedestrian 2. The wearable device is used to input the crossing request and collect the driving parameters of the pedestrian 2, and transmit the crossing request and driving parameters to the vehicle-mounted V2X communication module and the roadside unit 1. The vehicle-mounted V2X communication module is used to receive crossing requests and driving parameters, judge the collision risk according to the driving parameters of the pedestrian 2, and send reminder information to the vehicle 3 . The roadside unit 1 is used to receive crossing requests and driving parameters, and perform collision ...

Abstract

The invention relates to a method for safely passing through an intersection without a signal lamp. The method comprises the following steps: a pedestrian sends an intersection passing request and driving parameters through wearable equipment; a vehicle-mounted V2X communication module obtains an intersection passing request and calculates a pedestrian movement track according to the driving parameters; and the pedestrian movement track is compared with the driving track of the current vehicle, whether a collision risk exists or not is judged, if so, an avoidance prompt is sent to the current vehicle, and otherwise, the intersection passing request is ignored. According to the method, the pedestrian can pass through the intersection in a pre-judgment mode, reference is provided for the driving behavior of a driver, sufficient operation time is reserved for parking or deceleration, the defect that the detection accuracy of a vehicle-mounted sensor is low under the conditions of rainstorm weather or dark night light and the like can be effectively overcome, the safety of vehicle driving is remarkably improved, and the method has a very important practical value.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a method for safely passing through intersections without signal lights. Background technique [0002] With the continuous increase of car ownership and the increasingly complex urban road traffic conditions, the intersection area has become a high-incidence area of ​​traffic accidents. According to statistics, about 90% of major traffic accidents occur at intersections. In order to improve driving safety, more and more cars have been equipped with active safety technology in recent years. Active safety technology generally uses on-board cameras or millimeter-wave radars to detect objects around the vehicle. When the surrounding objects are too close to the vehicle, or are on the driving route of the vehicle, it will actively prompt or alarm, even when it is expected that there will be an accident. When there is a risk of collision, the vehicle controller wil...
