Virtual warning sign processing method, device and system and medium

Abstract

The invention discloses a virtual warning sign processing method, device and system and a medium, and the method comprises the steps that whether the speed of a vehicle is smaller than a preset threshold value or not is determined in response to a pressing action of a danger alarm lamp after the vehicle is powered on if a first terminal is a vehicle-mounted terminal; if YES, the vehicle state is determined to be an emergency stop state; if the vehicle state is the emergency stop state, vehicle information is obtained, a warning message is generated according to the vehicle information, and thewarning message is reported to a cloud platform; the cloud platform generates a virtual warning sign according to the warning message and pushes the virtual warning sign to at least one second terminal; and the second terminal displays the virtual warning sign. According to the invention, the danger caused by using a physical warning sign is avoided, the method is not limited by the position relation between the vehicle and the coming vehicle or the sight of a driver, and a more reliable warning effect is achieved.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a method, device, system and medium for processing a virtual warning sign. Background technique [0002] If a vehicle breaks down or other emergencies require an emergency stop during the driving process, the driver should usually drive the car into the emergency lane to stop, turn on the hazard alarm flashing lights, and quickly set the warning sign in the direction of the coming vehicle.
