Security passing system and security prewarning method

Abstract

A security prewarning method comprises the following steps: monitoring the speed of a second vehicle (20) approaching in the rear side direction of a first vehicle (10) through a tail radar (120) mounted at the tail part of the first vehicle (10) as well as the distance between the first vehicle (10) and the second vehicle (20); when the speed of the second vehicle (20) is not in a safe speed range, or the distance between the first vehicle (10) and the second vehicle (20) is not in a safe distance range, sending prewarning to pedestrians passing right ahead of the first vehicle (10) through a prewarning device (124) mounted at the head part of the first vehicle (10), so as to remind the pedestrians of the approaching vehicle. The invention further provides a security passing system. By using the method and the system, when passing right ahead of the vehicle, the pedestrians can be reminded of the rear approaching vehicles, so that the passing safety of the pedestrians can be ensured.

Description

technical field [0001] The invention relates to a safe passage system and method, in particular to a safe passage system installed on a large vehicle and a method for reminding pedestrians to pass safely by using the safety system. Background technique [0002] With the continuous improvement of people's living standards, the number of vehicles has increased year by year. At present, safe passage has become one of the social focuses. In order to improve driving safety, vehicle manufacturers will install various safety devices on vehicles, for example, install airbags on vehicles, which will pop up when the vehicle collides to protect the safety of drivers. However, these safety devices are mainly designed and developed from the perspective of protecting the driver or passengers in the vehicle, and are not designed and developed from the perspective of protecting pedestrians. For example, when a pedestrian walks in front of a stopped large vehicle (such as a bus, large bus,...

However, these safety devices are mainly designed and developed from the perspective of protecting the driver or passengers in the vehicle, and are not designed and developed from the perspective of protecting pedestrians

For example, when a pedestrian walks in front of a stopped large vehicle (such as a bus, large bus, large truck, etc.), the pedestrian may not see that there are other vehicles coming from behind the large vehicle due to the large size of the large vehicle. Pedestrians are coming, and the drivers of other vehicles cannot see pedestrians passing by large vehicles due to the occlusion of large vehicles. If the speed of other vehicles is too fast at this time, it is easy to cause traffic accidents and cause loss of life and property.
