Privileged vehicle passage method, device and system

Abstract

The invention provides a privileged vehicle passage method, device and system. Avoiding information is calculated and obtained through unprivileged vehicles according to second position information of current running of the unprivileged vehicles, planned route information, first position information and speed information; the unprivileged vehicles perform corresponding avoiding treatment according to the avoiding information; the unprivileged vehicles are made to obtain the planned route information and the like of privileged vehicles as early as possible and avoid the privileged vehicles in advance according to the information. Thus, the roads ahead of privileged vehicles are free of the congestion caused by gathering of unprivileged vehicles and the privileged vehicles can arrive at destinations in time.

Description

technical field [0001] The present invention relates to communication technology, in particular to a privileged vehicle access method, device and system. Background technique [0002] Privileged vehicles refer to police cars, ambulances, fire engines or other vehicles that require priority passage. [0003] In the prior art, due to the particularity and importance of the tasks performed by privileged vehicles, vehicles generally need to avoid vehicles along the way during driving, so as to ensure that they can reach the destination in the shortest time. Though, the roof of the privileged vehicle is equipped with siren or warning light class sound and light alarm device, the effective range of action of this type of device is all very limited. When the road in front of the privileged vehicle is very congested, even if the task to be performed by the privileged vehicle is urgent, it can only pass after waiting patiently for the vehicle in front to be cleared. This will undou...
